目的分析苏州地区绝经后妇女的骨质疏松发生情况及相关影响因素。方法采用随机整群抽样方法从苏州市抽取261例45~70岁的绝经后妇女进行流行病学调查,收集相关资料,测定桡骨远端骨密度,分析骨质疏松患病情况及其影响因素。结果 261例中,骨质疏松92例(35.25%)(A组),骨量减少117例(44.83%)(B组),骨量正常52例(19.92%)(C组)。A组的绝经年限、分娩次数、腰围、腰臀比(WHR)、胆固醇、甘油三酯、低密度脂蛋白等指标均高于B、C组(P<0.05)。绝经年限(OR=2.29)和WHR(OR=3.79)是骨质疏松的危险因素(P<0.01)。结论绝经时间长、中心性肥胖和多产妇女是骨质疏松的高风险人群。
Objective To analyze the incidence and related factors of osteoporosis in postmenopausal women in Suzhou area. Methods A total of 261 premenopausal women aged 45-70 years were collected from Suzhou City by randomized cluster sampling method to collect epidemiological data. The bone mineral density was measured and the prevalence of osteoporosis and its influencing factors were analyzed. Results Among the 261 cases, 92 cases (35.25%) of osteoporosis (group A), 117 cases (44.83%) of osteopenia (group B) and 52 cases (19.92%) of normal bone mass (group C). The number of menopause, number of deliveries, waist circumference, WHR, cholesterol, triglyceride and low density lipoprotein in group A were higher than those in group B and C (P <0.05). Menopausal years (OR = 2.29) and WHR (OR = 3.79) were risk factors for osteoporosis (P <0.01). Conclusions Long postmenopausal women with central obesity and prolonged labor are at high risk of osteoporosis.
