Nutrition, metabolism, and hypertension. A comparative survey between dietary variables and blood pressure among three nationalities in China.
The prevalence of hypertension among Kazak, Han, and Uygur nationalities living in Xinjiang Autonomous Region was 15.3%, 4.2%, and 2.1%, respectively; 257 men (92, 92, 83 subjects, respectively), aged 40-59 years were studied. The variables analyzed were serum total cholesterol, total protein, albumin, alpha-GT, triglyceride, plasma fibrinogen, and glucose concentrations; and urinary Na, K, Ca, Mg, urea nitrogen, taurine, sulfate, and NaCNS (an index of smoking), content. The data on nutritional variables indicated that Kazak subjects have a higher intake of sheep meat and milk, add salt to milk and tea, and take little starchy food, fresh fruits, and vegetables, as compared with Han and, especially, Uygur subjects. Statistical analysis showed Na intake (Na/K) exerted a prehypertensive effect; Ca (Ca/Mg) was implicated in blood pressure regulation; an antihyperlipidemic factor may exist in the Kazak diet; animal protein is correlated with elevated blood pressure; alcohol consumption may contribute to hypertension; and a mosaic model of metabolic disturbances, including high blood pressure, high blood sugar, impaired fibrinolytic activity, and hyperlipidemia, appear to exist.
