| Objective To conduct epidemiological survey and investigate the preventive measures of osteoporosis in the elderly. Methods From June 2017 to June 2018, 5432 elderly people in our area were investigated for osteoporosis. Results The incidence of osteoporosis was 12.44%. The average bone mineral density of lumbar spine L2-4 was (0.820±0.111) g/cm2, the average bone mineral density of the femoral neck was (0.818±0.103) g/cm2, the average bone density of the femoral neck trochanter was (0.712±0.100) g/cm2, and the average bone density at the Ward's triangle was (0.704±0.112) g/cm2. In those with osteoporosis, the proportion of women, age, and the percentage consuming alcohol, drinking milk daily, not taking oral calcium tablets and physical exercise < 30min/d were 59.17%, (75.20±9.28), 60.95%, 69.08%, 65.83% and 57.25%, respectively, which were significantly higher than those without osteoporosis (P<0.05). Logistic regression analysis showed that women and age were risk factors for osteoporosis (OR=1.761 and 1.964, P<0.05), and the amount of daily milk consumption, taking oral calcium tablets and physical exercise were protective factors of osteoporosis in the elderly (OR=0.725, 0.661 and 0.718, P<0.05). Conclusion The incidence of osteoporosis is relatively high in the elderly, targeted measures should be taken according to the relevant risk factors to reduce the incidence of osteoporosis. |
