摘要
本文应用中美心血管病流行病学合作研究在北京和广州35～54岁工人农民中进行心血管病基线调查时的膳食调查813例资料,对比分析北京和广州工农男女共八个组的营养素摄入量和血脂水平,并在北京和广州两大组人群内分析有关营养因素和血脂的关系。结果表明,在控制年龄、性别、工农、体重指数及饮酒量等混杂变量的条件下,“膳食脂质分值”与血清总胆固醇及高密度脂蛋白胆固醇均呈显著正关联,饱和脂肪酸在北京人群内、膳食胆固醇在广州人群内与血清总胆固醇呈显著正关联。饱和及单不饱和脂肪酸与高密度脂蛋白胆固醇呈正关联,而碳水化合物则呈负关联。未见上述各营养素与血清甘油三酯有显著关联。
Using a standardized 24-hr recall method, baseline dietary surveys were done in a total of 813 workers and farmers of Beijing and Guangzhou in autumn of 1983—84 and spring of 1985-86 under the PBC-US cooperative study on CVD epidemiology. A common food table was used to estimate the nutrients intake. The relationship between nutrition factors and serum lipids within population was studied by multiple regression analyses adjusted for age, sex, occupation (workers or farmers), body mass index and alcohol intake. For each subject, the mean intake of nutrients in 6 days (3 in autumn and 3 in spring) was used as independent variables, and the mean serum lipids from two measurements was taken as dependent variable. Results showed that the Keys 'dietary lipid score' was positively associated with TC and HDL-C, and specifically, saturated fatty acid within Beijing group and dietary cholesterol within Cuangzhou group were positively associated with serum TC. Saturated and monounsaturated fatty acids were found to he related positively and carbohydrates negatively to HDL-C.
