广东居民抗氧化维生素摄入量与个体特征因素的关系

为找出膳食抗氧化维生素摄入量与年龄、性别、文化程度、家庭总收入、工作状况等个体特征之间的关系 ,1995年在广东省调查了 92 1人 ,其中男性 418人 ,女性 5 0 3人 ,年龄 2 5～ 84岁 ,收集了社会经济状况资料 ,及用食物频数法收集了调查对象最近 1年食物摄入状况资料。结果显示 ,多种抗氧化维生素和热量的摄入量男性高于女性 ;年龄较大者各种抗氧化维生素的摄入量较低 ;较高文化程度者及家庭每年总收入高者摄入维生素 E较多 ;个体户和农民各种抗氧化维生素的摄入量普遍较其他职业者低 ,男性待业者及女性退休者维生素 E的摄入量明显高于其余各组 ;除肥胖组以外 ,体重指数高者膳食各种抗氧化维生素摄入量较多。本研究表明 ,由于社会经济环境不同 ,抗氧化维生素的摄入量各有差异 ,老年人、文化程度低者及农村地区需要加强健康饮食的指导 ,如增加豆类、水果和蔬菜的摄入量。

Dietary intake of antioxidant vitamins and personal demographic characteristics of Guangdong residents

The study aim at revealing the associations between the intake of dietary antioxidant vitamins and personal characteristics on age, sex, education, working status and household gross income etc. The intake of antioxidant vitamins in a population of Guangdong Province was studied. A total of 418 males and 503 females, aged 25-84 year were interviewed, and questionnaires on socio demography and on a 12-month food intake frequency (FFQ) were completed in 1995 The daily average intake of antioxidant vitamins and energy was higher in male than in female. Older subjects consumed lesser antioxidant vitamins. The vitamin E intake of higher education persons as well as high family income females (>15001RMB) was higher. Individual business owners and farmers consumed lesser antioxidant vitamins than the other counterparts. The highest vitamin E intake was found in the currently unemployed men and retired women. BMI was positively associated with the intake of antioxidant vitamins excepted for the obesity group. The result suggests that the consumption of antioxidant vitamins varies with characteristics of socio demographic status. Health promotion programs, such as suggestions on eating more fruits and vegetables should be targeted at the elderly, the less educated, lower income families and rural community.
