Bone loss and the rate of osteoporosis have been on the rise among menopausal women. Osteoporosis is a silent disease. Fracture may occur without warning if the disease is not detected and prevented early. Thus, all menopausal women are encouraged to engage in behavior modifications to prevent occurrence of osteoporosis. Of the lifestyle modifications, exercise is the only method that can simultaneously improve low bone mineral density (BMD), and raise muscle strength and endurance. Current studies have demonstrated that exercise can increase BMD or prevent bone loss among postmenopausal women. Therefore, a community nurse should understand the effects of exercise on bone health among menopausal women and establish suitable exercise model and prescription to assist women. In addition, regular exercise habit should be encouraged to prevent the occurrence of osteoporosis and fracture as well as achieve health promotion.
