In men and women 65 years of age or older who are living in the community, dietary supplementation with calcium and vitamin D moderately reduced bone loss measured in the femoral neck, spine, and total body over the three-year study period and reduced the incidence of nonvertebral fractures.
Recall of early menstrual history and menarcheal body size: after 30 years, how well do women remember?

Overall, a woman's recall of menarcheal age and body size was better than recall of cycle length and occurrence of regularity, and the failure to identify certain menstrual characteristics as exposures for subsequent disease may reflect limitations in the accuracy and precision of the recalled measures.
Vitamin D and Its Role in Skeletal Muscle
This review discusses the clinical and laboratory studies that have examined a role of vitamin D in skeletal muscle and indicates that vitamin D status is positively associated with muscle strength and physical performance and inversely associated with risk of falling.
Association between serum osteocalcin and markers of metabolic phenotype.

Serum osteocalcin concentration was inversely associated with blood markers of dysmetabolic phenotype and measures of adiposity, and these findings should be considered hypothesis generating, and they need to be replicated in human studies designed to test the hypothesis that osteocalin affects metabolism.
The Vitamin D Receptor Start Codon Polymorphism (FokI) and Bone Mineral Density in Premenopausal American Black and White Women

The SCP polymorphism, detected with the endonuclease FokI, appears to influence peak bone density, particularly at the femoral neck, particularly in premenopausal American women.
Calcium intake influences the association of protein intake with rates of bone loss in elderly men and women.

Increasing protein intake may have a favorable effect on change in BMD in elderly subjects supplemented with calcium citrate malate and vitamin D.
Vitamin D and African Americans.
- S. Harris
- MedicineJournal of NutriLife
- 1 April 2006
Clinicians and educators should be encouraged to promote improved vitamin D status among blacks (and others) because of the low risk and low cost of vitamin D supplementation and its potentially broad health benefits.
Effect of vitamin D supplementation on wintertime and overall bone loss in healthy postmenopausal women.
- B. Dawson-Hughes, G. Dallal, E. Krall, S. Harris, L. Sokoll, G. Falconer
- MedicineAnnals of Internal Medicine
- 1 October 1991
At latitude 42 degrees, healthy postmenopausal women with vitamin D intakes of 100 IU daily can significantly reduce late wintertime bone loss and improve net bone density of the spine over one year by increasing their intake of vitamin D to 500 IU daily.
Plasma calcidiol, season, and serum parathyroid hormone concentrations in healthy elderly men and women.

- MedicineAmerican Journal of Clinical Nutrition
- 1997
The high prevalence of lower wintertime calcidiol values may increase risk of bone loss in elderly men and women.
Seasonal changes in plasma 25-hydroxyvitamin D concentrations of young American black and white women.

- MedicineAmerican Journal of Clinical Nutrition
- 1 June 1998
Although it is well established that blacks have denser bones and lower fracture rates than whites, elevated parathyroid hormone concentrations resulting from low 25-hydroxyvitamin D concentrations may have negative skeletal consequences within black populations.
