Fatty acid composition of breastmilk during lactation may be a factor in the development of childhood overweight later in life. 96 mother/infant pairs at 3 months postpartum were interviewed, and anthropometrics were measured onsite. There were no statistically significant differences in maternal percent body fat according to infant feeding practice. EBF infants were significantly fatter than MF but not FF infants. Mothers who consumed at least 4.5 grams of trans fatty acids/day were more likely to have body fat •30% than those consuming less (OR=7.57; 95% CI: 1.44, 39.76), and their infants were also more likely to have body fat •24% (OR=3.29; 95% CI: 1.08, 10.03). Fatty acid composition of the maternal diet may affect both maternal and infant body composition. More research is warranted regarding maternal dietary and breastmilk fatty acid composition, their affects on maternal and infant body composition, and the development of childhood overweight later in life.
