Effect of Lactation and Weaning on Calcium Status

Kalkwarf, Heidi J.

Abstract

The objectives of this study are to determine whether there are significant changes in bone mineral density during lactation and the post-weaning periods, and whether these changes are influenced by dietary calcium intake. Two randomized calcium supplementation trials have been conducted, one during the first 6 months of lactation and the other during 6 months' post-weaning. Changes in total body, distal forearm and lumbar spine bone mineral content were determined by dual energy x-ray absorptiometry. The effects of lactation and calcium intake on calcium homeostasis and bone metabolism were also examined.
