The contribution of feeding mode to obesogenic growth trajectories in American Samoan infants
Hawlye NL, Johnson W, Nu'usolia O, McGarvey ST
What is already known about this subject
Samoan adults are recognized for their particularly high body mass index and prevalent obesity. While Polynesians are understudied, in other populations infancy is a critical period in the development of obesity. Breastfeeding has been shown to attenuate obesity risk.
What this study adds
Samoan infants show remarkably rapid gain in weight but not length in early infancy resulting in a prevalence of overweight and obesity far higher than has been previously reported elsewhere.
Breastfeeding is associated with slower weight gain in infancy suggesting that its protective benefits for obesity risk are generalizable outside of European-derived populations.
