摘    要:目的描述绝经期妇女动物性食品摄入情况,探讨摄入动物类食品对骨质疏松的影响。方法随机抽取哈尔滨市区281名年龄在50岁至65岁之间的绝经期妇女。采用CRF健康问卷表进行调查;并使用双能X线骨密度仪(NorlandXR-36型)测量腰椎骨的骨密度。利用SAS9.1统计软件对绝经期妇女动物性食品摄入情况进行描述;控制混杂因素后,使用logistic回归分析骨质疏松与摄入动物性食品之间的关系。结果绝经期妇女平均每日肉类摄入量为82.25g,海产品为44.51g,蛋类为56.70g,奶制品为205.59g;单因素分析显示:年龄、肥胖、学历、收入、生育个数、蔬菜类及牛肉类食物与骨质疏松的患病有关(P<0.05)。多因素分析显示,动物性食物中的牛肉为骨质疏松发生的保护因素、蛋类为骨质疏松发生的危险因素(P<0.05)。结论绝经期妇女肉类、蛋类平均每日摄入量高于推荐摄入量,水产品、奶类平均每日摄入量低于推荐摄入量;食用动物性食品中的牛肉可能预防骨质疏松的发生,但过多的摄入蛋类可能增加骨质疏松的患病风险,未发现饮用牛奶与骨质疏松的患病存在关联。

Abstract:Objective The objective of the study was to describe the status of dietary intake in animal food of postmenopausal females,and also ascertain the kinds of animal food which affecting osteoporosis. Methods Postmenopausal women ( n = 281 ) aged 50 - 65 were randomly selected in urban areas of Harbin. General condition,diet,exercise,reproductive history,and psychological aspects were obtained by CRF ( Case report form) questionnaire survey. Using dual-energy X-ray absorptiometry at the lumbar spine to measure Bone mineral density( BMD) . The diagnosis of osteoporosis based on the diagnostic criteria which was formulated by WHO in1994. We described the status of dietary intake in animal food and the influencing factors using single-factor regression by statistical software SAS9. 1. Adjusted for mixed factors,using logistic regression to analyze the relationship between animal food and Osteoporosis. Results The average food consumption per day of postmenopausal females: meat 82. 25 g,fisheryproducts 44. 51 g,eggs 56. 70 g,dairy 205. 56 g. Singlefactor regression analysis revealed that factors associated with osteoporosis were Age,number of births,Obesity,high education,high income,vegetable and beef ( P < 0. 05) . Multiple-logistic regression analysis showed that egg could increase the risk of osteoporosis; beef and vegetable could reduce the risk of osteoporosis; Milk has no effect on osteoporosis ( P < 0. 05 ) . Conclusion The consumption of meat and eggs,both higher than the recommended,the consumption of milk,fish and Seafood below the recommended ; adequate amounts of beef could prevent the occurrence of osteoporosis,excessive amounts of eggs could increase the risk of osteoporosis, we did not find the milk on the impact of osteoporosis.
Keywords:Animal food  Postmenopausal  Osteoporosis  Logistic regression
