Carter SA, Parsons CM, Robinson SM, et al. - Researchers used data from the Hertfordshire cohort study (HCS) to investigate the impact of infant milk feeding on bone health in later life by contrasting the effect of breastfeeding and bottle feeding on lumbar spine and femoral neck bone mineral content (BMC) and bone mineral density (BMD). Health visitors collected information on infant milk intake, birth weight (kg), and weight at 1 (kg) in Hertfordshire between 1931 and 1939. Between 1998 and 2004, BMC and BMD measurements were taken by DXA scan. Significant correlations in males between infant milk feeding and lumbar spine BMD suggest that breastmilk may be beneficial to male babies' bone health. No significant connections were found between infant milk feeding and bone health for females. The evidence presented here underlines the possible lifelong benefits of breastfeeding, and may illustrate the differences between male and female osteoporotic risk factors.
