Vitamin D requirements during pregnancyBonny Specker
Ethel Austin Martin Program in Human Nutrition, South Dakota State University, Brookings, SD 57007
Am J Clin Nutr 80:1740S-7S. 2004..Results concerning benefits for fetal growth and bone development are inconclusive.

Ethel Austin Martin Program in Human Nutrition, South Dakota State University, Brookings, SD 57007, USA
J Nutr 134:691S-695S. 2004..There is evidence of calcium intake-by-gene and calcium intake-by-physical activity interactions among toddlers and young children. The long-term effects of these early nutritional influences on later bone health are unknown... - Bone response to jumping is site-specific in children: a randomized trialNeil Johannsen

Bone 33:533-9. 2003..10). We conclude that skeletal loading increases total body and leg BMC in children, but may not have a positive effect at sites that are predominantly trabecular bone during periods of rapid growth (i.e., peripubertal period)... - Randomized trial of physical activity and calcium supplementation on bone mineral content in 3- to 5-year-old childrenBonny Specker
