An epidemiology survey of bone mineral density and osteoporosis in 1204 elderly people in Xuzhou area / 中国综合临床

ABSTRACT

Objective To analyze the changes of bone mineral density (BMD) and the incidence of osteoporosis in elderly people in Xuzhou area by measuring BMD, and provide reference to osteoporosis prevention and control. Methods From 2005 to 2008, BMD were measured in 1204 elderly people by dual energy X-ray absorptiometry (DEXA). The measurement included the neck of femur and L2-4 of lumbar. All subjects were divided into multiple sections with every 5 year interval. Osteoporosis was diagnosed according to the criteria of BMD peak minus 2. 5 SD. BMD values and the incidence of osteoporosis were analyzed among different age and gender groups. Results BMD of different sites decreased year by year in both male and female in Xuzhou area. After 55years of age BMD decreased more in female than in male ( P ＜ 0. 01 ). The incidence of osteoporosis in female was higher than that in male. Conclusions We should reinforce the health education on osteoporosis prevention. Intervention should be conducted in females older than 55 years and males older than 65 years to decrease the occurrence of osteoporosis.
