To investigate the association between trans fatty acid and adiposity, 96 mother-infant pairs (exclusive breastfed; mixed fed; and formula fed) at 3 months postpartum were interviewed; body composition was measured onsite using the BOD POD and PEA POD for mothers and infants, respectively.Subjects/Methods:This was a cross-sectional study. Participants were recruited via convenience sampling from Athens-Clarke and surrounding counties of the state of Georgia. Data were analyzed using 2, analysis of variance and regression.Results:There were no significant differences in maternal percent body fat by feeding group (32.70, 33.70, and 35.73%, for exclusive, mixed and formula feeding, respectively). Exclusively breastfed infants had higher percent body fat (24.87%) compared with their mixed-fed counterparts (22.15%) but not formula-fed infants (23.93). Mothers who consumed at least 4.5 g of trans fatty acids/day were 5.8 times more likely to have body fat ≥ 30% than those consuming less (odds ratio5.81; 95% confidence interval (CI), 1.05, 32.32), and their infants were over two times more likely (odds ratio2.13; 95% CI, 0.75, 6.01) to have body fat ≥ 24%.Conclusions:Trans fatty acid content of the maternal diet may be associated with both maternal and infant body composition in the early postpartum period. More research is warranted regarding maternal dietary and breastmilk fatty acid composition and their effects on maternal and infant body composition and the development of childhood overweight later in life. © 2010 Macmillan Publishers Limited All rights reserved.enAdiposityBody compositionBreastfeedingInfantMothersTrans fatty acidArticle
