1 Introduction ​

Premature birth, defined as birth occurring before 37 weeks of gestation, represents a significant global health challenge, affecting approximately 10% of live births annually[1][2]. Advances in neonatal care have markedly improved survival rates for preterm infants; however, these individuals often face a range of long-term health complications that can impact their physical, cognitive, and psychosocial development throughout their lives[2][3]. The transition from the intrauterine to the postnatal environment is particularly precarious for preterm infants, who may experience disruptions in organ development and increased vulnerability to various health conditions[4][5].

Understanding the long-term implications of premature birth is critical for healthcare providers, policymakers, and families, as it informs strategies aimed at improving health outcomes and quality of life for this vulnerable population[1]. The significance of this research lies not only in addressing the immediate medical needs of preterm infants but also in recognizing the potential for chronic health issues that may emerge later in life. These issues include, but are not limited to, chronic respiratory conditions, cardiovascular diseases, metabolic disorders, and neurodevelopmental impairments[2][4]. Furthermore, psychosocial factors such as mental health concerns and social integration challenges can exacerbate the difficulties faced by individuals born preterm[1][6].

Current literature indicates that the long-term health outcomes associated with premature birth are multifaceted, often resulting from a complex interplay of biological, environmental, and social determinants[1][3]. Chronic respiratory conditions, such as bronchopulmonary dysplasia (BPD), and cardiovascular complications have been well-documented, highlighting the need for ongoing medical surveillance and intervention[3][4]. Neurodevelopmental issues, including cognitive impairments and learning disabilities, further complicate the life trajectory of individuals born preterm[1][6]. The psychosocial implications, including increased rates of anxiety and depression, necessitate a comprehensive approach to care that encompasses not only physical health but also mental and emotional well-being[1][6].

This review aims to synthesize current knowledge on how premature birth affects long-term health outcomes, focusing on various dimensions, including chronic health conditions, neurodevelopmental issues, and psychosocial factors. We will begin by defining premature birth and discussing its epidemiology, including global and regional statistics, as well as the risk factors associated with premature birth. Following this, we will delve into the long-term physical health outcomes, highlighting chronic respiratory conditions, cardiovascular health, and metabolic disorders. The neurodevelopmental outcomes will be examined in detail, focusing on cognitive impairments, learning disabilities, and behavioral and emotional issues. We will then explore the psychosocial implications of premature birth, addressing social relationships, mental health concerns, and the impact on family dynamics. Finally, we will discuss interventions and support strategies, including early intervention programs, educational support, and healthcare follow-up and monitoring, before summarizing the key findings and highlighting areas for future research.

In conclusion, understanding the long-term implications of premature birth is crucial for developing effective interventions and support systems for affected individuals. By examining the interplay between various health outcomes and the factors influencing them, we can better address the needs of this population and improve their overall quality of life. The gaps in current literature will also be identified, underscoring the necessity for ongoing research in this critical area of public health.

2 Definition and Epidemiology of Premature Birth ​

2.1 Definition of Premature Birth ​

Premature birth, defined as birth before 37 weeks of gestation, has significant implications for long-term health outcomes. The epidemiology of premature birth indicates that it remains a prevalent concern, with approximately 10% of births classified as preterm. As advances in neonatal care have improved survival rates, particularly for extremely preterm infants, there is a growing recognition of the associated long-term health risks that these individuals face.

Research has consistently shown that individuals born preterm are at a heightened risk for various chronic health conditions later in life. For instance, preterm birth is linked to an increased likelihood of developing respiratory, cardiovascular, and metabolic diseases, as well as neurodevelopmental disorders and psychiatric conditions. Specifically, Casey Crump et al. (2016) noted that survivors of preterm birth may experience elevated risks of respiratory, cardiovascular, and kidney diseases, alongside diabetes and metabolic syndrome, indicating a multifaceted burden of adult morbidities that stems from early life complications associated with prematurity [7].

Moreover, studies have demonstrated that the effects of prematurity can manifest early in life and persist into adulthood. For example, research by Elaine M. Boyle et al. (2012) found that children born moderate/late preterm (32-36 weeks) and early term (37-38 weeks) had poorer health outcomes at ages 3 and 5 compared to full-term peers, suggesting a "dose-response" effect of prematurity on health [8]. Additionally, Nick L. Dobson et al. (2024) highlighted that preterm birth is associated with long-term alterations in skeletal muscle health, potentially impacting physical function and quality of life [1].

The long-term consequences of prematurity are compounded by the complexities of growth and nutrition during the early stages of life. Alexandre Lapillonne and Ian J. Griffin (2013) emphasized that even brief periods of undernutrition during critical developmental windows can adversely affect later health outcomes, particularly in terms of cardiovascular and metabolic health [9]. This indicates the necessity for targeted nutritional interventions in preterm infants to mitigate long-term health risks.

In summary, premature birth is a significant public health issue with enduring implications for long-term health. The interplay of early developmental challenges, nutritional factors, and the resultant chronic health conditions underscores the need for ongoing research and improved healthcare strategies to support individuals born preterm throughout their life course. The awareness of these long-term health consequences is essential for healthcare providers to ensure appropriate monitoring and intervention strategies for this vulnerable population [2][10].

2.2 Global and Regional Statistics ​

Premature birth significantly impacts long-term health outcomes across various domains, including metabolic, cardiovascular, respiratory, and neurodevelopmental health. Infants born preterm face an increased risk of chronic illnesses and conditions that can persist into adulthood, thereby affecting their quality of life and overall health trajectory.

Preterm birth, defined as birth before 37 weeks of gestation, continues to contribute disproportionately to neonatal morbidity and long-term disabilities. Epidemiological studies indicate that individuals born preterm are at a heightened risk for several adverse health outcomes, including hypertension, insulin resistance, diabetes, obesity, and various neurodevelopmental disorders [1][7][9]. The long-term consequences of these conditions can lead to increased all-cause mortality and a diminished quality of life in young adults [1].

The health risks associated with preterm birth are not limited to the neonatal period. Studies have shown that the burden of disease is significant even among those born moderately or late preterm (32-36 weeks gestation). For instance, a cohort study revealed that health outcomes for children born late/moderate preterm are worse than those for full-term infants, indicating a "dose-response" effect of prematurity on health [8]. The data suggest that children born between 32-36 weeks have a higher likelihood of experiencing hospital admissions and long-standing illnesses compared to their full-term counterparts [8].

Moreover, the relationship between preterm birth and adult morbidities is complex and multifaceted. Early life events, such as nutritional status and growth rates during infancy, play a critical role in shaping long-term health outcomes. For example, evidence suggests that reduced growth during hospitalization adversely affects neurodevelopment, while growth during late infancy and childhood is a significant determinant of later metabolic and cardiovascular health [9].

In addition to metabolic and cardiovascular concerns, the impact of preterm birth extends to respiratory health. Individuals born preterm are more susceptible to chronic respiratory conditions later in life, and the onset of such conditions often emerges during adulthood, tracing back to early life vulnerabilities [3].

As the survival rates of preterm infants continue to improve due to advancements in neonatal care, it becomes increasingly important for healthcare providers to be aware of the potential long-term effects of prematurity. This awareness is crucial for enabling early detection of diseases and implementing targeted lifestyle modifications that can mitigate the risks associated with prematurity [2][7].

In summary, premature birth has profound and lasting implications for health, with evidence indicating increased risks for a range of chronic conditions. Continued research is essential to further understand these long-term effects and to develop effective interventions aimed at improving health outcomes for individuals born preterm.

2.3 Risk Factors Associated with Premature Birth ​

Premature birth, defined as birth before 37 weeks of gestation, significantly impacts long-term health outcomes across various domains, including physical, metabolic, and neurodevelopmental health. The epidemiology of premature birth indicates that approximately 10% of all births are preterm, a figure that remains concerning given the increasing survival rates of these infants due to advances in neonatal care [7].

The long-term health consequences of premature birth are profound. Research has demonstrated that individuals born preterm are at a heightened risk for a range of chronic conditions, including respiratory diseases, cardiovascular disorders, diabetes, metabolic syndrome, and neuropsychiatric disorders [7][9]. Specifically, preterm infants face increased susceptibility to hypertension and insulin resistance in adulthood, which can lead to significant morbidity and mortality [9]. Moreover, studies indicate that the risk of developing conditions such as obesity and diabetes is markedly elevated in individuals born preterm [1].

The effects of prematurity on health are not limited to physical ailments; they extend to mental health as well. Extremely preterm infants, those born before 28 weeks of gestation, are particularly vulnerable to neurodevelopmental impairments, intellectual disabilities, and psychiatric disorders that can persist into adulthood [6]. The long-term psychiatric outcomes for these individuals often reflect a trajectory of difficulties that begin in early childhood and can evolve into more complex challenges during adolescence and adulthood [6].

Several risk factors are associated with premature birth, including maternal health conditions (such as hypertension and diabetes), lifestyle factors (like smoking and poor nutrition), and socio-economic determinants [10]. The implications of these risk factors are multifaceted, influencing not only the likelihood of preterm delivery but also the subsequent health trajectories of the affected infants. The role of early nutrition has also been highlighted as a critical factor that can influence long-term outcomes, suggesting that interventions during hospitalization and after discharge could potentially mitigate some of the adverse effects associated with prematurity [10].

Furthermore, the impact of gestational age at birth on health outcomes has been studied extensively. Research indicates a "dose-response" relationship between gestational age and health outcomes, with those born late or moderate preterm (32-36 weeks) and early term (37-38 weeks) experiencing worse health outcomes compared to full-term infants [8]. This underscores the importance of understanding the continuum of prematurity and its associated risks, as the majority of preterm births fall into these categories rather than being classified as extremely preterm [8].

In summary, the consequences of premature birth extend well beyond the neonatal period, affecting various aspects of health and well-being throughout the lifespan. Awareness of these long-term effects is crucial for healthcare providers, enabling better management and care strategies for individuals born preterm as they transition into adulthood.

3 Long-term Physical Health Outcomes ​

3.1 Chronic Respiratory Conditions ​

Premature birth is significantly associated with various long-term health outcomes, particularly chronic respiratory conditions. Research indicates that preterm birth, especially among infants born before 32 weeks of gestation, can lead to persistent respiratory morbidity throughout childhood and into adulthood.

Survivors of preterm birth frequently exhibit adverse respiratory outcomes, including an increased incidence of chronic obstructive pulmonary disease (COPD) and other respiratory illnesses. Specifically, the development of bronchopulmonary dysplasia (BPD)—a chronic lung disease commonly seen in premature infants—exacerbates the risk of long-term respiratory complications. BPD is characterized by impaired lung development, which leads to airflow obstruction and ongoing respiratory symptoms that can persist into adulthood (McGrath-Morrow & Collaco, 2019) [4].

A nationwide cohort study revealed that preterm birth occurs in approximately 6.43% of deliveries, and there is a negative correlation between gestational age at birth and respiratory morbidity. As gestational age increases, the rates of respiratory hospitalizations decrease, and the duration of hospital stays shortens, indicating that the earlier the birth, the higher the likelihood of respiratory complications (Sompolinsky et al., 2025) [11].

Moreover, even among those who are moderately and late preterm, there is an increased susceptibility to respiratory issues, suggesting that the implications of prematurity extend beyond the most extreme cases (Tsang et al., 2025) [3]. Infants born late preterm (34-37 weeks) are also at risk for respiratory distress and other complications, as their lung development is prematurely interrupted, leading to long-term respiratory morbidity (Pike & Lucas, 2015) [12].

The mechanisms underlying these long-term respiratory issues include not only the initial disruption of normal lung development due to preterm birth but also the effects of neonatal interventions, such as mechanical ventilation and oxygen therapy, which can cause further lung injury (Briana & Malamitsi-Puchner, 2023) [13].

It is crucial to recognize that while some survivors of BPD may show improvement with age, many continue to experience chronic lung dysfunction, highlighting the importance of monitoring and addressing these health challenges throughout their lives (El Mazloum et al., 2014) [14]. The long-term respiratory outcomes of preterm birth underscore the necessity for early interventions and continuous healthcare support to mitigate the lasting impacts on lung health.

In conclusion, the long-term health consequences of premature birth, particularly concerning chronic respiratory conditions, are profound and multifaceted. These outcomes necessitate a comprehensive approach to neonatal care and ongoing follow-up to manage and potentially alleviate the long-term burden of respiratory morbidity in this vulnerable population.

3.2 Cardiovascular Health ​

Premature birth, defined as delivery before 37 weeks of gestation, significantly impacts long-term cardiovascular health. The prevalence of preterm birth has been on the rise, affecting approximately 9.6% of all births globally, which translates to nearly 13 million births annually[15]. This condition is associated with a spectrum of adverse cardiovascular outcomes that persist into adulthood.

Research indicates that preterm infants exhibit distinct cardiovascular characteristics compared to their term-born counterparts. These infants often present with higher heart rates and lower blood pressure, alongside altered autonomic control, which is reflected in abnormalities in heart rate variability and baroreflex control[15]. Such instability in systemic cardiovascular parameters can impose stress on the developing neonatal brain, increasing the risk of complications such as cerebral hemorrhage or hypoxia due to immature cerebral hemodynamics[15].

As individuals born preterm transition into adulthood, they face an elevated risk of developing cardiovascular diseases. Studies have shown that preterm birth is linked to a reduced cardiac reserve, smaller ventricular volumes, and increased vascular stiffness[16]. For instance, follow-up studies have demonstrated that preterm-born individuals are at greater risk for ischemic heart disease and heart failure as they age[17]. The alterations in cardiac structure and function observed in this population, such as smaller cardiac chamber sizes and impaired ventricular function, further contribute to their heightened cardiovascular risk[17].

Additionally, a systematic review and meta-analysis encompassing over 5.8 million women revealed that women who experienced preterm deliveries have a significantly increased risk of future cardiovascular diseases. The risk ratios for conditions such as coronary heart disease and stroke were notably elevated, with a two-fold increase in deaths caused by coronary heart disease[18]. These findings underscore the importance of recognizing preterm birth as a critical factor in assessing long-term cardiovascular health risks.

The physiological stressors associated with premature birth, including exposure to chorioamnionitis and intra-uterine growth restriction, can disrupt normal cardiovascular development[19]. The resultant long-term effects manifest as increased mean arterial pressure and abnormal cardiac morphology, which may predispose these individuals to cardiovascular complications later in life[19].

In conclusion, the implications of premature birth extend far beyond the neonatal period, significantly influencing cardiovascular health in adulthood. Continuous monitoring and proactive management of cardiovascular risk factors in individuals born preterm are essential to mitigate the long-term health consequences associated with this condition. The emerging understanding of the cardiovascular sequelae of preterm birth calls for an integrated approach to healthcare for these individuals, ensuring that their unique health challenges are addressed throughout their lifespan[20].

3.3 Metabolic Disorders ​

Premature birth has significant long-term health implications, particularly concerning metabolic disorders. The evidence indicates that individuals born preterm are at an increased risk for various metabolic and cardiovascular conditions in adulthood.

Research shows that preterm birth is associated with a heightened risk of developing components of metabolic syndrome, which includes obesity, hypertension, and insulin resistance. A systematic review and meta-analysis encompassing 43 studies highlighted that adults born preterm exhibited significantly higher fat mass, elevated systolic and diastolic blood pressure, and increased fasting glucose and insulin levels compared to their term-born counterparts. Specifically, preterm individuals showed higher values for body mass index, waist circumference, and other markers of metabolic health, indicating a strong association between prematurity and metabolic syndrome in later life [21].

Moreover, preterm birth can lead to chronic health issues such as type 2 diabetes mellitus and cardiovascular disease. This correlation is attributed to several factors, including the altered intrauterine environment and growth patterns during early life. The impact of prematurity on metabolic health may also stem from disruptions in normal organogenesis, leading to long-term dysfunction in metabolic regulation [22].

In addition to direct metabolic consequences, premature birth has been linked to a range of other health challenges, including increased oxidative stress, which is a risk factor for hypertension and metabolic syndrome. The association between oxidative stress and chronic diseases emphasizes the multifaceted nature of health outcomes following preterm birth [23].

Furthermore, specific studies have noted that metabolic bone health is also adversely affected by preterm birth, as evidenced by lower bone mineral density and altered metabolic bone profiles in children born very preterm [24]. These skeletal issues can further compound the risk of metabolic disorders, as bone health is intricately linked to overall metabolic function.

Overall, the literature underscores that preterm birth is a significant risk factor for a variety of metabolic disorders, which may manifest as chronic health issues later in life. These findings highlight the importance of monitoring and potentially intervening in the health of individuals born preterm to mitigate these long-term risks.

4 Neurodevelopmental Outcomes ​

4.1 Cognitive Impairments ​

Premature birth significantly impacts long-term health, particularly in the realm of neurodevelopmental outcomes and cognitive impairments. The survival rates of infants born extremely preterm (before 28 weeks of gestation) have improved due to advancements in neonatal care; however, these infants are at an increased risk for a range of neurodevelopmental disorders and cognitive deficits that can persist throughout childhood and into adulthood (Johnson et al., 2019) [6].

One of the most notable consequences of preterm birth is the heightened vulnerability to cognitive impairments. Studies indicate that infants born preterm often exhibit reduced volumes of critical brain regions associated with cognitive functions, such as the parietal and sensorimotor cortices. These anatomical changes correlate with poorer cognitive outcomes, including lower intelligence quotients (IQs) compared to their term-born peers (Peterson, 2003) [25]. The neurodevelopmental trajectory of preterm infants is further complicated by factors such as early gestational age, low birth weight, and complications during the neonatal intensive care unit (NICU) stay, which all contribute to adverse cognitive outcomes (Xiong et al., 2012) [26].

Furthermore, preterm birth is associated with an increased incidence of learning disabilities and psychiatric disorders. Research has shown that the risk of developing these conditions is significantly higher in individuals who were born preterm compared to those born at term (Ream & Lehwald, 2018) [27]. The cognitive impairments often manifest as difficulties in language acquisition and social interaction, which are critical for overall development and educational achievement (Kratimenos et al., 2025) [28].

Longitudinal studies have revealed that the cognitive impairments observed in early childhood can persist into adolescence and adulthood. While some individuals may show improvements over time, a significant number continue to face challenges related to cognitive functioning, highlighting the need for ongoing support and intervention (Rogers & Hintz, 2016) [29]. The complex interplay of biological, environmental, and socio-economic factors further complicates the long-term outcomes for preterm infants, necessitating a multifaceted approach to intervention and support (Fraiman et al., 2022) [30].

In summary, premature birth has profound implications for long-term neurodevelopmental outcomes, particularly in cognitive domains. The increased risk of cognitive impairments and associated disorders underscores the importance of early identification and targeted interventions to improve the quality of life for individuals affected by prematurity. Continued research is essential to elucidate the mechanisms underlying these impairments and to develop effective strategies for neuroprotection and rehabilitation in this vulnerable population.

4.2 Learning Disabilities ​

Premature birth is a significant factor influencing long-term health, particularly in relation to neurodevelopmental outcomes and learning disabilities. Infants born preterm, especially those born extremely preterm (before 28 weeks of gestation), are at a markedly increased risk for a variety of neurodevelopmental disorders, including cognitive impairments and learning disabilities that can persist throughout childhood and into adulthood.

Research indicates that preterm birth remains a leading cause of lifelong neurodevelopmental disability globally, which poses substantial challenges not only for the affected individuals but also for their families and society at large (Benavente-Fernández et al., 2020) [31]. Neurodevelopmental challenges associated with preterm birth encompass a range of issues such as functional motor impairment, cognitive and speech delays, neurobehavioral disorders, and atypical social development (Fraiman et al., 2022) [30].

Longitudinal studies have shown that children who were born preterm are more likely to experience learning disabilities compared to their term-born peers. These disabilities can manifest in various forms, including difficulties with attention, memory, and processing information, which are crucial for academic success. The prevalence of learning disabilities in this population is often linked to the extent of brain injury or disruption in brain maturation that occurs during the neonatal period, exacerbated by factors such as infection, low birth weight, and prolonged hospitalization in neonatal intensive care units (Xiong et al., 2012) [26].

Furthermore, socioeconomic status (SES) has been identified as a critical modifier of neurodevelopmental outcomes in children born preterm. Lower SES is associated with variations in brain development and has been shown to influence the severity of neurodevelopmental impairments following early-life brain injuries (Benavente-Fernández et al., 2020) [31]. This underscores the need for targeted interventions that consider both biological and social determinants to improve long-term outcomes for preterm infants.

In summary, the impact of premature birth on long-term health, particularly concerning neurodevelopmental outcomes and learning disabilities, is profound. The challenges faced by preterm infants extend beyond the neonatal period, influencing their cognitive and educational trajectories well into adulthood. Continued research and intervention strategies are necessary to mitigate these risks and enhance developmental outcomes for this vulnerable population.

4.3 Behavioral and Emotional Issues ​

Premature birth significantly impacts long-term health, particularly concerning neurodevelopmental outcomes, behavioral, and emotional issues. Infants born preterm, especially those born extremely preterm (before 28 weeks of gestation), face heightened risks for a range of neurodevelopmental disorders that can persist throughout their lives.

The long-term consequences of preterm birth include cognitive impairments, behavioral problems, and psychiatric disorders. Research indicates that these children are at an increased risk for neurodevelopmental challenges such as functional motor impairment, cognitive and speech delays, neurobehavioral disorders, and atypical social development compared to their term-born peers[30]. Specifically, extremely preterm infants have been found to exhibit a higher incidence of psychiatric symptoms and disorders as they transition into young adulthood, with studies highlighting ongoing mental health challenges at 19 years of age[6].

The neurodevelopmental sequelae of preterm birth can be attributed to various factors, including the degree of prematurity, birth weight, and exposure to adverse conditions in the neonatal period. Infants born preterm are particularly vulnerable to brain injuries related to hypoxia-ischemia, inflammation, and other stressors encountered during early development[28]. These injuries can disrupt critical developmental processes, leading to neuronal and oligodendrocyte injury, which is linked to cognitive impairments and behavioral issues[28].

Moreover, brain imaging studies have revealed structural abnormalities in the brains of preterm infants, including reduced volumes of gray matter in regions associated with cognitive and emotional functioning. These anatomical changes are correlated with long-term cognitive outcomes, indicating that early brain development is crucial for future behavioral and emotional health[25]. The association between abnormal brain development and psychiatric disorders, including psychosis, underscores the complexity of the neurodevelopmental trajectories of individuals born preterm[32].

Furthermore, the socio-environmental context plays a significant role in the long-term outcomes of preterm infants. Racial and ethnic disparities have been documented in the prevalence of preterm birth and its associated morbidities, which may exacerbate inequities in health and development[30]. Access to post-discharge support services is critical in addressing these disparities and improving long-term neurodevelopmental outcomes[30].

In summary, the implications of premature birth on long-term health are profound, with significant risks for neurodevelopmental disorders and associated behavioral and emotional issues. Understanding the mechanisms underlying these outcomes is essential for developing targeted interventions to improve the health trajectories of preterm infants.

5 Psychosocial Implications ​

5.1 Social Relationships and Integration ​

Premature birth has significant implications for long-term health, particularly concerning psychosocial outcomes, social relationships, and integration. Infants born preterm and with low birth weight face an increased risk of neurodevelopmental challenges later in life compared to their term-born peers. These challenges encompass functional motor impairment, cognitive and speech delays, neurobehavioral disorders, and atypical social development, all of which can adversely affect social relationships and integration into society[30].

The literature indicates that preterm birth is linked to an elevated risk of developmental and adult psychiatric disorders, including psychosis. The neurodevelopmental sequelae of preterm birth, such as abnormal brain development and neuroinflammation, can result in persistent alterations in brain structure and function into adulthood. These alterations may impair functional connectivity in brain networks crucial for social interaction, leading to executive, social, and motor dysfunctions. Such dysfunctions may create behavioral vulnerabilities that contribute to difficulties in establishing and maintaining social relationships, ultimately impacting integration into social settings[32].

Moreover, the social brain circuitry, which is essential for processing social information, is particularly sensitive to the adverse effects of prematurity. Research suggests that infants born preterm are at a heightened risk for adverse neurologic, psychiatric, and cognitive outcomes, which can hinder their social-cognitive development. This may affect their ability to engage effectively in social interactions and establish relationships with peers, further complicating their integration into various social contexts[33].

The implications of these neurodevelopmental challenges extend into adulthood, where individuals who were born preterm may face difficulties in forming and maintaining social connections. This can result in social isolation, lower quality of life, and challenges in professional and personal relationships, emphasizing the importance of early intervention strategies aimed at enhancing social-cognitive development in this vulnerable population[30].

In summary, premature birth has profound and lasting effects on psychosocial outcomes, influencing social relationships and integration through a combination of neurodevelopmental challenges, psychiatric disorders, and difficulties in social-cognitive functioning. Addressing these issues through targeted interventions and support services is crucial for improving long-term health and social outcomes for individuals born preterm.

5.2 Mental Health Concerns ​

Premature birth has significant implications for long-term health, particularly concerning mental health and psychosocial development. The association between preterm birth and the increased risk of developmental and adult psychiatric disorders, including psychosis, is well-documented. Preterm birth is linked to abnormal brain development due to early exposure to the extra-uterine environment, compounded by factors such as neuroinflammation, neonatal brain injury, and genetic vulnerabilities. These factors can lead to lasting alterations in brain structure and function that persist into adulthood. Specifically, abnormal regional brain volumes and changes in white matter macro- and micro-structure can impair functional connectivity in networks critical for cognitive and social functioning, which is characteristic of psychotic illnesses. The resultant executive, social, and motor dysfunctions may underlie behavioral vulnerabilities that can culminate in psychotic symptoms later in life (Vanes et al. 2022) [32].

Furthermore, individuals born preterm exhibit heightened risks for neurodevelopmental disorders and psychiatric sequelae that extend throughout childhood and adolescence. Studies indicate that extremely preterm birth (before 28 weeks of gestation) significantly increases the likelihood of these adverse outcomes, raising questions about whether such challenges persist or evolve as these individuals transition into adulthood (Johnson et al. 2019) [6]. The long-term effects on mental health may also be influenced by the quality of neonatal care received and the psychosocial environment during development.

In addition to psychiatric concerns, preterm birth is associated with a variety of physical health challenges that can further complicate mental health outcomes. For instance, preterm infants are at increased risk for lung and brain health issues, diabetes, and obesity, all of which can negatively impact long-term quality of life and contribute to increased all-cause mortality in young adults (Dobson et al. 2024) [1]. The interplay of these physical health conditions with mental health outcomes suggests a multifaceted approach is necessary to understand the full impact of preterm birth on an individual's life course.

The recognition of preterm birth as a significant risk factor for later mental health issues is crucial, particularly in light of its prevalence; in 2014, approximately 10.6% of live births globally were preterm, underscoring the importance of addressing the psychosocial and mental health needs of this population (Kennedy et al. 2021) [34]. Advances in neonatal care have improved survival rates, yet the long-term implications for mental health remain a pressing concern that warrants ongoing research and attention in both clinical and community settings.

In summary, premature birth poses a substantial risk for a range of long-term health issues, particularly in the psychosocial domain, where it can lead to significant mental health concerns. Understanding these risks and their underlying mechanisms is vital for developing targeted interventions to support individuals born preterm throughout their lifespan.

5.3 Impact on Family Dynamics ​

Premature birth has significant long-term health implications, not only for the individual but also for family dynamics. Infants born preterm are at increased risk for a variety of chronic health conditions, which can profoundly affect family life and relationships.

Research indicates that individuals born preterm may experience a range of health issues as they grow older, including neurodevelopmental disorders, intellectual impairments, and psychiatric sequelae that persist throughout childhood and adolescence. These challenges can extend into adulthood, impacting not only the individual's quality of life but also their families' emotional and psychological well-being. Families often face the stress of managing ongoing medical needs, educational challenges, and potential behavioral issues associated with the child’s condition [6].

Moreover, the psychosocial implications of premature birth can alter family dynamics significantly. The emotional burden of caring for a child with health complications can lead to increased stress and anxiety among family members. Parents may experience feelings of guilt, frustration, or helplessness, particularly if their child faces developmental delays or health issues that require long-term care and support [34]. Siblings of preterm infants may also feel neglected or overwhelmed by the family's focus on the child with special needs, potentially leading to sibling rivalry or emotional distress [6].

Additionally, the economic burden associated with the healthcare needs of preterm infants can strain family resources. The costs of ongoing medical care, therapies, and potential educational support can be substantial, which may lead to financial stress and impact family cohesion [2].

The need for additional support services and interventions can further complicate family dynamics. Families may require assistance from healthcare professionals, social services, or educational specialists, which can create a reliance on external resources that might not always be readily available or accessible [1].

In summary, the long-term health effects of premature birth extend beyond the individual to influence family dynamics significantly. The emotional, psychological, and financial stresses associated with managing the health and developmental needs of preterm infants can alter relationships within the family, necessitating a comprehensive support system to address these multifaceted challenges.

6 Interventions and Support Strategies ​

6.1 Early Intervention Programs ​

Premature birth significantly impacts long-term health outcomes, influencing various aspects of physical and neurobehavioral development. Infants born preterm are at increased risk for chronic illnesses and developmental disorders, which can manifest throughout their lives. The evidence indicates that the effects of prematurity often extend into adulthood, with implications for both physical health and psychological well-being.

Research has shown that children born preterm are vulnerable to adverse long-term neurobehavioral outcomes, including cognitive, motor, and behavioral impairments. Early developmental interventions initiated within the first year after preterm birth are designed to positively influence the developmental trajectory of these children. Such interventions have been found to have a moderate effect on cognitive and behavioral outcomes up to preschool age, with some evidence supporting improved motor outcomes as well. Key components of effective early developmental interventions include starting as early as possible, ideally in the neonatal intensive care unit, and promoting developmental skills over time in an enriched environment. Parental involvement is also critical, as the parent-infant relationship significantly affects developmental outcomes, especially given the increased mental health challenges faced by parents following preterm birth (Spittle & Treyvaud, 2016) [35].

The long-term effects of interventions for preterm birth are still being explored. Strategies such as antenatal magnesium sulfate for fetal neuroprotection and corticosteroids for fetal lung maturation have shown short-term benefits; however, there is a notable lack of large-scale follow-up data assessing their long-term impact on childhood outcomes. Future research is necessary to establish the long-term efficacy of these interventions, ideally utilizing consistent outcome measures for comprehensive meta-analyses (Murray et al., 2017) [36].

Moreover, the significance of addressing modifiable risk factors through early interventions cannot be overstated. These interventions may help mitigate the increased risk of respiratory morbidity and other health complications associated with moderate and late prematurity. As highlighted by Tsang et al. (2025), understanding the health outcomes of this population is crucial, particularly given their higher prevalence compared to those born extremely or very preterm [3].

In summary, early intervention programs are essential in improving the long-term health outcomes of children born preterm. By addressing developmental challenges and supporting parental involvement, these programs can significantly enhance the quality of life for preterm infants and their families. Continued research and focus on effective strategies will be vital in reducing the long-term health burdens associated with prematurity.

6.2 Educational Support ​

Premature birth has significant implications for long-term health, influencing various aspects of physical and mental well-being. Research indicates that individuals born preterm are at increased risk for chronic conditions that can persist into adulthood. These conditions include respiratory diseases, cardiovascular issues, diabetes, and neuropsychiatric disorders, which may emerge due to the disruption of normal organogenesis associated with preterm birth [3][5][7].

In terms of educational support, children born preterm often face challenges that can affect their academic performance and overall development. Studies show that preterm infants are more likely to experience motor delays, cognitive impairments, and behavioral issues compared to their full-term counterparts [37]. For instance, extremely preterm infants (born before 28 weeks of gestation) are particularly vulnerable to neurodevelopmental disorders, which can lead to difficulties in learning and social interactions as they grow [6].

Interventions aimed at improving outcomes for preterm infants have been identified, focusing on both immediate and long-term strategies. These include providing early developmental support, such as tailored educational programs that cater to the specific needs of preterm children, as well as fostering environments that encourage their cognitive and emotional development [36][38]. Additionally, recognizing and addressing modifiable risk factors during early life can help mitigate some of the adverse effects associated with prematurity. This includes implementing support systems for families to enhance the educational experiences of these children [3].

Long-term follow-up studies are crucial to assess the effectiveness of these interventions and support strategies. Future research should aim to establish a comprehensive understanding of how educational support can be optimized for children born preterm, ultimately enhancing their quality of life and educational outcomes as they transition into adulthood [36].

6.3 Healthcare Follow-up and Monitoring ​

Premature birth significantly influences long-term health outcomes, necessitating tailored interventions and continuous healthcare follow-up to mitigate these effects. Research indicates that individuals born preterm are at an increased risk for a variety of chronic conditions, including respiratory, cardiovascular, and metabolic diseases, as well as neurodevelopmental disorders. This multifaceted risk profile underscores the importance of comprehensive healthcare strategies throughout the life course of these individuals.

Longitudinal studies have demonstrated that preterm infants face an elevated risk of chronic illnesses such as hypertension, diabetes, and metabolic syndrome in adulthood, with the origins of these conditions tracing back to early life. For instance, a review by Crump et al. (2016) highlights that improved early survival rates of preterm infants may lead to increased health risks later in life, including respiratory and cardiovascular diseases, underscoring the need for awareness among healthcare providers regarding the long-term outcomes associated with preterm birth [7]. Furthermore, Dobson et al. (2024) discuss the adverse skeletal muscle adaptations in individuals born preterm, indicating a potential impact on physical health and fitness that can extend into adulthood [1].

To effectively manage these risks, healthcare follow-up and monitoring are critical. Regular assessments should include evaluations of growth and development, screening for chronic conditions, and interventions aimed at promoting optimal health. For example, early nutrition plays a pivotal role in the health outcomes of premature infants, particularly those with very low birth weight or extremely low gestational age [10]. Thus, nutritional interventions during hospitalization and after discharge are essential components of follow-up care.

Moreover, the healthcare system should facilitate multidisciplinary approaches that encompass not only medical assessments but also psychosocial support. As evidenced by Pravia and Benny (2020), awareness of a patient’s birth history can lead to early detection of diseases and targeted lifestyle modifications, which are crucial for improving long-term health outcomes [2]. The need for continuous education and training for healthcare providers about the implications of prematurity is paramount, as it enables them to provide informed care that addresses the unique needs of this population.

In conclusion, the long-term health effects of premature birth necessitate a proactive approach to healthcare follow-up and monitoring. Interventions should be comprehensive, addressing both physical and psychosocial aspects of health to optimize outcomes for individuals born preterm. Enhanced awareness among healthcare providers, coupled with targeted interventions, can significantly improve the quality of life and health trajectories for this vulnerable population.

7 Conclusion ​

The long-term health implications of premature birth are profound and multifaceted, affecting individuals across various domains, including physical, cognitive, and psychosocial health. Key findings indicate that preterm infants face heightened risks for chronic respiratory conditions, cardiovascular diseases, metabolic disorders, and neurodevelopmental impairments. These health issues often persist into adulthood, leading to a complex interplay of medical and psychosocial challenges. Current research underscores the necessity for continuous healthcare follow-up and tailored interventions to address these risks effectively. Furthermore, understanding the intricate relationships between early-life experiences, growth patterns, and long-term health outcomes is essential for developing effective support strategies. Future research should focus on identifying specific interventions that can mitigate the adverse effects of prematurity and enhance the quality of life for this vulnerable population. There is also a critical need to explore the psychosocial dimensions of living with the consequences of premature birth, as family dynamics and mental health concerns play a significant role in the overall well-being of affected individuals. By prioritizing comprehensive care approaches that integrate physical health, developmental support, and psychosocial resources, we can better serve those impacted by premature birth and improve their long-term health trajectories.
