Insights
Infants born moderately preterm (32-33 weeks) and late preterm (34-36 weeks) face increased risks for short and long-term health issues. This challenges previous beliefs about outcomes for babies born near full term.
Area of Science:
- Neonatal Medicine
- Pediatric Health
- Developmental Pediatrics
Background:
- Historically, neonatal and pediatric clinicians believed outcomes for infants born near term were similar to full-term infants.
- Recent evidence challenges this assumption, indicating significant differences in short- and long-term morbidity and mortality.
- New terminology distinguishes moderately preterm (32-33 weeks) and late preterm (34-36 weeks) births, acknowledging associated immaturity.
Purpose of the Study:
- To review changing perceptions of gestational age in preterm infants.
- To explore emerging evidence on neonatal, childhood, adolescent, and adult outcomes for moderately and late preterm infants.
- To highlight morbidities and associated health, developmental, and educational challenges.
Main Methods:
- This is a review article.
- It synthesizes recent and emerging evidence from various studies.
- The review examines outcomes across different life stages.
Main Results:
- Infants born between 32-36 weeks gestation experience increased adverse outcomes compared to full-term infants.
- These outcomes include significant neonatal and childhood morbidities.
- Affected children face ongoing health care, developmental, and educational challenges.
Conclusions:
- The recognition of increased risks for moderately and late preterm infants necessitates a re-evaluation of healthcare and support services.
- Adverse outcomes span neonatal, childhood, and even adult life.
- Comprehensive primary, secondary, educational, and social support are crucial for this large, diverse population.
Abstract:
Until recently, there has been a strongly held belief on the part of neonatal and pediatric clinicians that outcomes for infants born close to term are not different from those of babies born at full term. In the last decade, however, this assumption has been challenged by reports suggesting that this is not correct, and highlighting differences in morbidity and mortality both in the short and long term. This has led to development of new terminology to more accurately reflect the impact of immaturity associated with birth at 32-33 weeks (moderately preterm) and 34-36 weeks (late preterm) of gestation. These babies account for around 5-7% of all births and more than 75% of the preterm births in developed countries, so this new recognition of the associated increase in adverse outcomes may have a substantial impact on health care services. This review article will discuss the changing perceptions and concepts of gestational age in the preterm population, and explore the recent and emerging evidence around neonatal, early childhood, school-age, adolescent and adult outcomes for babies who are born moderately preterm and late preterm. It highlights important neonatal and childhood morbidities and will summarize associated health care, developmental and educational problems of affected children. The implications for the provision of ongoing primary and secondary health care, educational and social support to this large and heterogeneous group of individuals will be discussed.
