Extended breast-feeding (BF) significantly enhances postpartum weight loss compared to limited breast-feeding (FF). Mothers who breast-fed for at least 6 months experienced greater weight reduction and fat loss.

Area of Science:

  • Maternal Health
  • Human Lactation
  • Postpartum Recovery

Background:

  • Postpartum weight retention is a significant concern for many mothers.
  • Breast-feeding is often recommended for maternal health benefits, including weight management.

Purpose of the Study:

  • To investigate the impact of breast-feeding duration on postpartum weight loss and body composition.
  • To determine the relationship between breast-feeding frequency, milk output, and maternal weight changes.

Main Methods:

  • A matched cohort study comparing women who breast-fed for >= 12 months (BF) versus <= 3 months (FF).
  • Measurements included weight and triceps-skinfold thickness until 24 months postpartum.
  • Breast-feeding frequency and milk energy output were monitored in the BF group.

Main Results:

  • BF women showed significantly greater weight loss (4.4 kg vs 2.4 kg) from 1 to 12 months postpartum compared to FF women.
  • BF mothers experienced a net loss in triceps-skinfold thickness, while FF mothers gained fat at this site.
  • Breast-feeding frequency and duration correlated with weight loss between 6 and 12 months postpartum.

Conclusions:

  • Lactation promotes postpartum weight loss, particularly when breast-feeding continues for at least 6 months.
  • Extended breast-feeding is associated with reduced maternal adiposity postpartum.
