To the Editor Calcium, vitamin D, or combined calcium and vitamin D supplements were associated with a lower fracture incidence in community-dwelling older adults in a systematic review and meta-analysis.1 The authors suggested that these findings did not support the routine use of these supplements in community-dwelling older people.
Calcium plus vitamin D supplementation has been widely recommended to prevent osteoporosis. Therefore, the research question should be whether calcium, vitamin D, or combined calcium and vitamin D supplements are associated with a lower incidence of osteoporotic fracture in community-dwelling older adults. There are many reasons for fracture. Falls is an independent factor influenced by living environment, eating habits, disease, age, and balance, among other factors.
