1、中老年人饮食营养状况调查与分析1994?中老年人饮食营养状况调查与分析洪忠新，武力，张立红,黄金茹9调查研究？【摘要】FI的了解屮老年人饮食，营养状况，针对存在的问题,提供改进措施•方法使用体重计和便携式牛物电阻抗分析仪分别测定225名中老年人的身高，体重，体质指数(BMI)和体脂(BF).按照体脂将调查对象分为体脂正常组(BF<30%,n=108)和体脂超标组(BF〜30%,n=117)採用半定量食物频度调查表(SFFQ)调查两组中老年人平均每周所进食物的频率，同时对他们的户外活动，唾眠情况及慢性病患病率进行调查•结果受试对象的B
2、MI为(24.4±2.6)ks/m2,BF为(30.4±6.2)%(其中BF930%者占52%);体脂正常组和体脂超标组慢性病患病率分别为28.0%与66.7%;半定量食物频度调查结果发现体脂超标组猪肉和硬果类摄入频率明显高于体脂正常组(P<0.05).而西红柿，茶，粥和粗粮的摄入频率均显着低于体脂正常组(P<0.01).两组受试者均有喝牛奶，吃绿叶蔬菜和水果的习惯,但鱼类，海产品及豆类的摄入频率均较少•两组受试者户外活动和睡眠间差异无显着性意义(P>0.05).结论中老年人群中体脂超标者所占比例较犬，慢性病患病率也较高
3、.这可能与他们猪肉和硬果类的摄入频率较高及西红柿，蔡，粥和粗粮的摄入频率较低有关.【关键词】营养;中老年人;半定量食物频度调查;生物电阻抗分析【中图分类号】R151.42【文献标识码】A【文章编号】1007—9572(2006)23—1994—03ASurveyonDietaryandNutritionalStatusoftheMiddleandOldAgedPeopleHONGZhong—xin,ULi,ZHANGLi—hong,etal.DepartmentofClinicalNutritionofFriendshipHospitaL
