IntroductionFalls are a major threat among the older population, as they cause morbidity and mortality, as well as expensive healthcare costs. After menopause, women have a greater risk of falls than men. One indispensable intrinsic factor is reduced muscle strength. Reduced muscle mass occurs in almost 30% of the population aged >60 years, and more than 50% in those who aged >80 years. Some studies have shown the correlation between vitamin D deficiency and the loss of muscle strength, as well as its function in older people. A study in Indonesia by Rinaldi et al. found a positive correlation between 25(OH)D3 serum level and muscle strength of femoral quadriceps in older women (r = 0.327; P = 0.009).Despite being located in a region with supposedly abundant sunlight exposure, older adults in Indonesia are still at great risk of vitamin D deficiency, as they have reduced synthesis of 25(OH)D3 in their skin, low vitamin D in their diet, lack of sunlight exposure, reduced hydroxylation in their kidneys and polymorphism of vitamin D receptors (VDR). A study carried out by Setiati et al. found that the prevalence of vitamin D deficiency in Indonesian older women living in nursing homes was 35.1%.
