Dietary calcium intake and bone loss from the spine in healthy postmenopausal women

Abstract: Controversy exists over the relationship between calcium intake and axial bone loss. We measured bone density of the spine (L2-4) by dual photon absorptiometry (DPA) two times, 7 mo apart, in 76 healthy postmenopausal women aged 40-70 y. Ca intake was assessed by food-frequency questionnaire. Women with a Ca intake less than 405 mg/d lost spine density at a rate that was significantly greater than that of women with an intake greater than 777 mg/d, p = 0.026. There appears to be a threshold of Ca intake below … Show more

“…[17][18][19] The weaker association of adolescent milk consumption with bone mineral density may reflect less variation in intake (adults have greater independence in beverage choices), inaccuracies of longer recall, or the lower per capita milk consumption during the Great Depression, which coincided with many participants' adolescent years. Alternatively, it may reflect the fact that most members of this cohort were children or teenagers when vitamin 'D, which mediates the absorption of calcium,5 was first added to the US milk supply.0…”
