Calcium and Osteoporosis

Effects of physical activity and dietary calcium intake on bone mineral density and osteoporosis risk in a rural Thai population.

Article Summary:

This is a review of the study that determines the effect of dietary calcium intake and physical activity on bone mineral density in postmenopausal Thai women. A total of 129 Thai women participated in the study. Dietary calcium intake, energy expenditure, and sunlight exposure were assessed. Bone mineral density at the femoral neck, lumbar spine, and distal radius were measure by using dual-energy X-ray absorptiometry. The result of the study shows that dietary calcium intake, energy expenditure, and years since menopause were significant and independent predictors of bone mineral density. The risk of osteoporosis was higher in women with lower dietary calcium intake, lower energy expenditure, and greater years since menopause. The study suggests that each of these three variables is an independent risk factor for low bone mineral density.
