Evidence for Sexual Dimorphism in the Neonatal Fat Mass Response to Maternal Long-Chain PUFA Intake
This article at a glance
- Omega-3 long-chain polyunsaturated fatty acid (LCPUFA) intake during pregnancy has been associated with a small but significant increase in the average length of a healthy pregnancy, as well as the body weight of a newborn.
- In this study the investigators address the sex-specific effects of maternal LCPUFA intake during pregnancy on body compositon of healthy full-term babies.
- The results suggest that the ratio of omega-6 to omega-3 LCPUFA intake favors development of adipose tissue in newborn girls, and that higher DHA intake is associated with increased ponderal index of males at birth, a measure of larger body size unrelated to fat mass.
