Comparison of the intake of food and nutrients between the residents in areas with different incidence of lung cancer

目的：了解和比较肺癌低发地区（江苏省南京市）和肺癌高发地区（辽宁省本溪市）居民的膳食营养素摄入状况。方法：在南京和本溪2个地区随机选取年龄35～55岁的居民各200人,男女约占半数。采用连续7日24小时膳食回顾法,实地入户进行膳食调查,并比较两地居民膳食营养素的摄取情况。结果：与南京居民相比,本溪居民谷类、根茎类、油类、能量、脂肪、碳水化合物、膳食纤维、维生素B1、维生素E、钾、钠、镁摄入量明显较高,而深色蔬菜、畜肉类、家禽类、奶类、水产类、坚果类、糖类、糕点类、蛋白质、胡萝卜素、视黄醇、烟酸、铁、硒摄入量明显较低。结论：不同肺癌发生地区居民的硒、胡萝卜素、蛋白质、铁、能量、脂肪、畜肉类、家禽类、水产类、深色蔬菜、谷类、油类、坚果的摄入量有明显差异。

Objective：To learn and compare the intake of food and nutrients between the inhabitants in Nanjing（with low incidence of lung cancer） and in Benxi（with high incidence of lung cancer）.Methods： Residents aged between 35 to 55 years old were randomly selected,200 were from Nanjing and 200 were from Benxi,the ratio for male to female was about 1：1.A dietary survey was made for continuous 7 days with the method of 24 hours recalling,the intake of food and nutrients was then compared.Results： Compared with the residents in Nanjing,the intake was obviously higher for cereals,roots,oil,energy,fat,carbohydrates,fiber,vitamin B1,vitamin E,potassium,sodium and magnesium in the residents of Benxi,while it was significantly lower for dark green leafy vegetables,meat,poultry,milk,marines,nuts,sugar,cakes,protein,carotene,vitamin A,niacin,iron and selenium.Conclusions：There is obvious difference between the inhabitants in areas with different incidence of lung cancer for the intake of selenium,carotene,protein,iron,energy,fat,meat,poultry,marines,dark green leafy vegetables,cereals,oil and nuts.
