Birthweight, gestational age, and early school trajectory.

Area of Science:

• Child Development
• Public Health
• Pediatrics

Background:

• Birthweight and gestational age are critical determinants of newborn health and long-term child development, potentially influencing cognitive abilities.
• Existing research has not comprehensively examined the simultaneous association of birthweight and gestational age with multiple aspects of school trajectory.

Purpose of the Study:

• To analyze the association between birthweight and gestational age with school entry.
• To explore the relationship between birthweight and gestational age with grade repetition and school dropout.

Main Methods:

• Utilized longitudinal data from the Ouagadougou Health and Demographic Surveillance System (2008-2014 births).
• Employed discrete-time survival models for school entry, grade repetition, and dropout analyses.
• Used Poisson regression to assess the association with age at school entry.

Main Results:

• Low birthweight (<2000g and 2000-2499g) was significantly associated with a decreased probability of school entry and an increased age at school entry.
• Children weighing <2000g had a 31% lower probability of school entry and entered school 7% later.
• Gestational age, grade repetition, and school dropout were not significantly associated with birthweight or gestational age.

Conclusions:

• Low birthweight negatively impacts school entry and age at school entry in Ouagadougou.
• Maternal and prenatal care initiatives to prevent low birthweight are crucial for mitigating long-term developmental challenges.
• Further longitudinal research is recommended to deepen the understanding of birth development and school trajectory relationships.
