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。
In this study, we used the epidemiological study of cardiovascular disease between China and the United States to study 813 cases of dietary survey of baseline survey of cardiovascular diseases among worker peasants aged 35-54 years in Beijing and Guangzhou. The data of eight groups of workers and peasants in Beijing and Guangzhou were compared and analyzed. Intake and blood lipid levels, and in Beijing and Guangzhou, two groups of people in the analysis of nutritional factors and the relationship between blood lipids. The results showed that there was a significant positive correlation between dietary lipid score and serum total cholesterol and high density lipoprotein cholesterol under the control of mixed variables such as age, gender, worker and peasant, body mass index and alcohol consumption. Saturated fatty acids in Beijing Within the population, dietary cholesterol was positively correlated with serum total cholesterol in Guangzhou population. Saturated and monounsaturated fatty acids and high-density lipoprotein cholesterol were positively correlated, while carbohydrates were negatively correlated. None of the above nutrients and serum triglycerides were significantly associated.
