Effects of breastfeeding on postpartum weight change in Japanese women: The Japan Environment and Children's Study (JECS).

ABSTRACT:

Aim

The aim of this study was to examine the relationship between breastfeeding and postpartum maternal weight change.

Method

This study used data from the Japan Environment and Children's Study (JECS), an ongoing nationwide birth cohort study. Participants were categorized into two groups: full breastfeeding (FB) and non-full breastfeeding (NFB) groups. Postpartum weight changes between the FB (n = 26,340) and NFB (n = 38,129) groups were compared.

Results

At 6 months postpartum, mean weight retention was significantly lower in the FB group than in the NFB group (0.2 vs 0.8 kg, respectively, p<0.001). Weight retention differed by pre-pregnancy body mass index (BMI), with postpartum weights of overweight (pre-pregnancy BMI 25.0-29.9) and obese (pre-pregnancy BMI ≥30.0
