Objective: To investigate the association of birth weight
(BW), and body composition (BC) in healthy, one-year-old
infants in Jamaica.
Methods: A cross-sectional study where body composition measured as fat-free mass (FFM) and fat mass (FM) was assessed by whole-body bioelectrical impedance analysis (BIA) and skinfold thickness measurements in a sample of 101 healthy one-year-old infants (58 girls and 43 boys). Pearson's correlation test and multiple linear regression were used to analyze the association between birth weight and body composition.
Results: Data on 101 infants was used in the analysis. Significant associations were observed between birth weight and fat-free mass(r=0.35.p=0.0001) and fat mass(r=0.25. p=0.013) at the simple bivariate level, weight and length significantly correlated with body composition using the multiple linear regression. Excess body fat was seen in 12% girls and 26% boys. Socioeconomic status did not impact the association of birth weight and body composition in this study.
Conclusion: In this sample of one-year-old infants, birth weight was associated with fat-free mass and fat mass, and weight and length were associated with fat-free mass, fat mass, and body fat.
