STUDY ON THE RELATIONSHIP BETWEEN DIETARY CARBOHYDRATE AND GLYCEMIC LOAD AND DYSLIPIDEMIA RISK IN ADULTS / 营养学报

ABSTRACT

Objectives To analyze the relationship between dietary carbohydrate and glycemic load(GL) and the plasma lipid level and dyslipidemia risk. Method The sample of adults above 18y of age from "National Survey on Nutrition and Health Status of the Chinese People 2002" was used,excluding pregnant women,mothers and people who controled their diets. Data of GI from China Food Composition 2002 and International Glycemic Index Table 2002 were used. The dietary GL as the indicator of dietary carbohydrate was calculated by multiplying the carbohydrate content of each food by its glycemic index,then multiplied by frequency of consumption and summed up from all food. Correlation analysis,multiple regression and Logistic regression were used to analyze the relationship between dietary GL and plasma lipid level and dyslipidemia risk. Results Dietary GL remained inversely associated with plasma total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) . With the increase of dietary GL,the risk of hypercholesterolemia and high blood LDL-C decreased. In the meantime dietary GL remained negatively associated with plasma high density lipoprotein cholesterol(HDL-C) . With the increase of dietary GL,the risk of low blood HDL-C increased. Dietary GL remained inversely associated with plasma triglyceride(TG) ,but showed no significant influence on risk of hypertriglyceridemia. Conclusion The traditional Chinese dietary pattern which is characterized by cereals as staple food is helpful to decrease dyslipidemia risk.
