Breastfeeding protects against postmenopausal hip fracture in women

Several studies have reported that fetal development, and the hormonal hypoestrogenemia/hyperprolactinemia that occurs during lactation may result in reduced peak bone mass, bone loss, or both. However epidemiological studies reported that nulliparity is associated with higher risk for fracture and lower bone mineral density. The authors [1] studied the effect of parity and breastfeeding on risk for hip, wrist, and nonvertebral fragility fractures in 4681 postmenopausal women aged 50 to 94 years in the Tromso study from 1994 to 2010.

The risk for hip, wrist or fragility fractures did not differ between parous and nulliparous postmenopausal women. However, compared with women who did not breastfeed after birth, women who breastfed had a 50% lower risk of hip fracture and a 27% lower risk for fragility fractures after adjustments, in particular for age and body mass index. Similar risk for wrist fracture was observed for these two groups of women. The risk of hip fracture significantly decreased by 12% for every 10 months of breastfeeding duration. No significant variation of bone mineral density was observed for longer breastfeeding duration and multiparity.

These data indicate that pregnancy and breastfeeding have no long-term deleterious effects on bone fragility and fractures and that breastfeeding may contribute to a reduced risk for hip fracture after menopause.

Good stuff!
