Objectives:
Low bone mineral density (LBMD) significantly contributes to global morbidity and mortality, especially in postmenopausal women. However, its burden in premenopausal women remains underrecognized. This study evaluated the global burden, temporal trends and future projections of LBMD-related outcomes.
Methods:
Data were obtained from the Global Burden of Disease 2021 dataset covering 204 countries. Premenopausal and postmenopausal women from 1990 to 2021 were included. Incidence, mortality and disability-adjusted life years (DALYs) were extracted, and age-standardized rates were calculated. The study explored demographic and epidemiologic changes, applied inequality indices and employed a Bayesian Markov chain Monte Carlo model to forecast trends through 2035.
Results:
Between 1990 and 2021, LBMD-related mortality rose by 27.39% (95% uncertainty interval [UI] 16.83-39.69) among premenopausal women and 138.73% (95% UI 98.45-186.25) among postmenopausal women. In 2021, the postmenopausal age-standardized rate (27.92 per 100,000) was 63.5 times higher than that of premenopausal women (0.44 per 100,000). By 2035, although rates may decline, overall deaths and DALYs will likely increase due to population growth and aging.
Conclusion:
Despite decreasing standardized rates, the absolute burden of LBMD continues to grow. Early screening and targeted prevention, especially for postmenopausal and underrecognized premenopausal women, is crucial to lessen its global impact.

01:29Bone Disorders
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...
