Abstract:
Calcium is a requisite nutrient in maintaining bone health. High calcium intake has been recommended for osteoporosis prevention. However, the relationship of dietary calcium intake with bone mineral density (BMD) in the elderly remained controversial. We aimd to evaluate the association between them in older adults. Using data from the Nutrition and Health Examination Survey (NHANES, 2001-2006), we conducted multivariate logistic regression analyses to explore the association of dietary calcium intake with lumbar BMD in older adults. Subgroup analyses were also performed. We included 2904 older adults aged ≥ 60 (43.63% men) for analysis. Higher dietary calcium intake was associated with greater lumbar BMD after adjusting for other covariates. In the subgroup analysis stratified by sex, this positive association existed in women, but not in men. In conclusion, for older adults aged ≥ 60, higher dietary calcium intake is associated with a higher lumbar BMD in women, but not in men.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
