Abstract: Objective To investigate the relationship between the proportion of carbohydrate intake and the morbidity of hypertension in middle aged and elderly people in Zhang Fang village, Fang Shan District, Beijing. Methods Totally 150 middle aged and elderly villagers were selected randomly in Zhang Fang Village,Fang Shan District, Beijing. The blood pressure and parameters of anthropometry were measured and the diet intake was investigated. According to the criterion we selected 132 villagers as the objects of our study. According to the proportion of carbohydrate intake,we separated the villagers into two groups,high proportion of carbohydrate intake group (the proportion of carbohydrate intake was more than 60%,high carbohydrate group,HC group),and none high proportion of carbohydrate intake group (the proportion of carbohydrate intake was less than 60%,none high carbohydrate group,NHC group). Results The morbidity of hypertension in this village in aged and elderly people was 59.1%. The morbidity of hypertension in HC group was higher than in NHC group significantly,especially the systolic blood pressure. There were no significant differences in age, gender, smoking, drinking, parameters of anthropometry,the intake of energy,carbohydrate,calcium,sodium and potassium between two groups. But the intake of fish, meat, nut and oil was significantly higher than those in HC group. And the intake of protein and fat was significantly higher than those in NHC group by conversion of nutrient. Conclusion When the proportion of carbohydrate intake was more than 60%,the morbidity of hypertension increased significantly,especially the systolic blood pressure. This phenomenon is related to the lower proportions of protein and fat,and has nothing to do with age, smoking, drinking, parameters of anthropometry and the intake of energy,carbohydrate,calcium,sodium and potassium.
