Effect of infant feeding on maternal body composition
MetadataShow full item record
This study evaluated maternal weight and percent body fat changes in exclusively breastfeeding versus mixed feeding mothers during the first 12 weeks postpartum, using the BOD POD. 24 mothers aged 19-42 years were studied. Pre-pregnancy weight was higher in mixed feeding mothers than in exclusively breastfeeding mothers (68.4 kg vs. 61.4 kg). At 12 weeks postpartum exclusively breastfeeding mothers had lost more total body weight than mixed feeding mothers (4.41 4.10 versus 2.79 3.09 kg; p<0.35). There was no significant difference in fat weight change between the two groups (4.38 2.06 versus 4.17 2.63 kg; p<0.89). Mixed feeding mothers lost more percent body fat than exclusively breastfeeding women (1.90 4.18 versus 1.71 3.48 kg p<0.91). Exclusively breastfeeding mothers consumed more calories than mixed feeding mothers (1980.01 618 kcal versus 1541.26 196 kcal p<0.08). Exercise levels were however higher in mixed feeding mothers than exclusively breastfeeding mothers. Our results suggest that exclusively breastfeeding leads to greater weight loss than mixed feeding.
