Effect of infant feeding on maternal body composition.

Bottom Line: However, mixed feeding mothers lost slightly more percent body fat than exclusively breastfeeding mothers (1.90 +/- 4.18 kg versus 1.71 +/- 3.48 kg), but the difference was not statistically significant.The trend in percent body fat loss was significant among exclusively breastfeeding mothers (p = 0.034) but not mixed feeding mothers (p = 0.081).This suggests that there is the need to encourage mothers to exclusively breastfeed as a means of overweight and obesity prevention.

ABSTRACT

Background: Women gain total body weight and accrue body fat during pregnancy. Breastfeeding has been suggested as an efficient means of promoting postpartum weight loss due to its high energy cost. We investigated the effect of infant feeding mode on maternal body composition.

Methods: 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. Twenty four mothers aged 19 - 42 years were studied. Participants were recruited from Athens-Clarke County and surrounding areas of the State of Georgia, USA. The study was conducted between November 2005 and December 2006.

Results: Prepregnancy weight was higher in mixed feeding mothers than in exclusively breastfeeding mothers (68.4 kg vs. 61.4 kg) but the difference was not statistically significant. At 12 weeks postpartum, exclusively breastfeeding mothers had lost more total body weight than mixed feeding mothers (4.41 +/- 4.10 kg versus 2.79 +/- 3.09 kg; p = 0.072). There was no significant difference in fat weight change between the two groups (4.38 +/- 2.06 kg versus 4.17 +/- 2.63 kg). However, mixed feeding mothers lost slightly more percent body fat than exclusively breastfeeding mothers (1.90 +/- 4.18 kg versus 1.71 +/- 3.48 kg), but the difference was not statistically significant. The trend in percent body fat loss was significant among exclusively breastfeeding mothers (p = 0.034) but not mixed feeding mothers (p = 0.081). Exclusively breastfeeding mothers consumed more calories than mixed feeding mothers (1980 +/- 618 kcal versus 1541 +/- 196 kcal p = 0.08). Physical activity levels were, however, higher in mixed feeding mothers than exclusively breastfeeding mothers.

Conclusion: Our results provide further evidence that exclusive breastfeeding promotes greater weight loss than mixed feeding among mothers even in the early postpartum period. This suggests that there is the need to encourage mothers to exclusively breastfeed as a means of overweight and obesity prevention.

Figure 1: a – Maternal postpartum weight change with respect to prepregnancy weight. b – Maternal postpartum weight change with respect to weight at delivery.

Mentions: Mean self-reported prepregnancy weight for study participants was 63.4 ± 10.9 kg. MF mothers weighed more than EBF mothers (68.4 kg vs. 61.4 kg; p = 0.159) and also had higher BMIs (25.9 kg/m2 vs. 22.1 kg/m2; p = 0.04). There was no significant difference in infant birth weight between the two groups (Table 2). Weight change among the two groups was compared with respect to self-reported prepregnancy weight and total weight at delivery. Although there was weight loss within both groups, the weight loss with respect to prepregnancy weight within the EBF group was significantly (p < 0.05) and consistently more at all time points than in the MF group (Figure 1a). There was no significant difference in weight loss both within and between groups with weight at delivery as the reference (Figure 1b). With respect to maternal weight at 2 weeks postpartum, the rate and amount of weight loss was greater for EBF than MF mothers throughout the duration of the study except at 4 weeks when weight loss was higher among MF groups (Figure 2; p = 0.072). Although, the difference in weight loss between the two groups was not significantly different, the magnitude of weight loss was greater among EBF mothers than MF mothers.
