Being too large for gestational age precedes childhood obesity in African Americans

Area of Science:

• Pediatrics
• Public Health
• Maternal-Child Health

Background:

• Childhood obesity is a significant public health concern, particularly in urban, minority populations.
• Identifying infants at high risk for developing obesity early in life is crucial for intervention.

Purpose of the Study:

• To examine the association between large-for-gestational-age (LGA) infants and the risk of childhood obesity.
• To evaluate the effectiveness of different birthweight percentile methods in identifying at-risk children within an inner-city African American population.

Main Methods:

• Retrospective cohort study involving 195 mother-child pairs aged 2-5 years.
• Collection of maternal, neonatal, socioeconomic, and nutritional data.
• Analysis of associations between birthweight percentiles (Alexander and customized) and childhood body mass index (BMI).

Main Results:

• The prevalence of childhood obesity was 18% in the study cohort.
• Higher Alexander and customized birthweight percentiles were correlated with increased childhood obesity risk.
• Large-for-gestational-age (LGA) infants demonstrated a 2.5-fold higher likelihood of childhood obesity compared to average-sized newborns.

Conclusions:

• Large-for-gestational-age (LGA) infants face the highest risk of developing childhood obesity in this specific urban African American cohort.
• Customized fetal growth percentiles are superior in identifying infants at the greatest risk for subsequent obesity.
• Maternal smoking emerged as an additional risk factor associated with childhood obesity.
