西安市城区绝经后妇女骨密度与女性生理因素的相关性

目的探讨绝经后妇女女性生理因素与腰椎、髋部骨密度的关系。方法对西安市城区281名绝经后妇女进行了女性生理因素的流行病学调查,并测定了腰椎、髋部骨密度。结果相关分析显示年龄、绝经年限、生育活产子女数和骨密度均呈显著负相关(P<0.01),而行经年限、身高、体重及体重指数(BMI)和骨密度均呈显著正相关(P<0.01)。比较骨质疏松组、骨量减少组和骨量正常组,年龄、绝经年限、生育活产子女数等,骨质疏松组明显高于骨量减少组和正常组(P<0.05);而平均每次月经持续天数、行经年限、身高、体重、BMI等,骨质疏松组明显低于骨量减少组和正常组(P<0.05)。结论西安市城区绝经后妇女的年龄、行经年限、绝经年限、生育活产子女数、身高、体重和BMI等与其腰椎和髋部的骨密度有明显的相关性。

Correlational analysis between bone mineral density and physiological characters of postmenopausal women in Xi'an urban area

Objective To investigate the correlation of bone mineral density(BMD) in lumbar vertebrae and hips with physiological characters of postmenopausal women in Xi'an urban area.Methods Epidemiological investigations,including the factors related to development of osteoporosis,were carried out in 281 postmenopausal women.Their BMD in lumbar vertebrae and hips was measured.Results The correlational analysis showed that a negative correlation of BMD with age,years since menopause and number of viable births,but a positive correlation with years of menstruation,height,weight and body mass index(BMI).Results showed that age,years since menopause and number of viable births were significantly higher in osteoporosis group women than in osteopenia group and normal group,However,average menstruation period,years of menstruation,height,weight and BMI were significantly lower in osteoporosis group than in the other groups.Conclution There exist significant correlations of BMD of lumbar vertebrae and hips with age,years of menstruation,menopause period,number of viable births,height,weight and BMI of urban women from Xi'an urban area.
