上海地区绝经后妇女骨质疏松危险因素分析

目的 探讨上海地区绝经后妇女骨质疏松的危险因素.方法 2008年6月至2008年9月从上海城市社区中年龄在45～80岁的绝经后妇女中随机抽取曾经双能X线骨密度测量仪测定并经临床医生确诊为骨质疏松者250人作为患者组,随机抽取非骨质疏松者250人作为对照组进行病例-对照研究.结果 单因素Logistic回归分析结果显示,年龄、文化程度、职业、绝经年限、体质指数(BMI)、是否经常摄入高钙食物及晒太阳、既往有非外伤性骨折、经常跌倒、糖尿病、慢性胃病、胃肠切除和腹泻与骨质疏松有关.多元Logistic回归模型进行分析显示,年龄、绝经年限、营养状态与骨质疏松关系最密切.结论 上海地区绝经后妇女发生骨质疏松与多种因素有关,早绝经、BMI低及老年妇女尤其要注意骨质疏松的防治.

Risk factor analysis for postmenopausal osteoporosis in Shanghai

Objective To investigate the risk factors for postmenopausal osteoporosis in Shanghai.Methods Five hundred postmenopausal community-dwelling women aged 45-80 years were recruited. The case-control study was performed from June 2008 to September 2008.A total number of 250 women with postmenopausal osteoporosis identified with their bone mineral density (BMD) were selected as case group, and 250 non-osteoporosis women were selected as control group. BMD was measured by dual energy X-ray absorption (DEXA). Results Univariate logistic regression analysis showed that age, eduction level, occupation, years since menopause, BMI, use of calcium,historyofnon-violencefracture,fall,diabetesmellitus,chronicgastricdiseases, gastrointestinal resection and diarrhea were related to osteoporosis.Multiple logistic regression showed that age, years since menopause and nutritional status were the risk factors for osteoporosis. ConclusionsThe occurrence of osteoporosis is related with many factors in postmenopausal women in Shanghai, and women with early menopause, low BMI and older age should pay more attention to the prevention and treatment of osteoporosis.
