A comparison of dietary and non-dietary factors of hypertension and normal blood pressure in a Chinese population.
The aim of this study was to compare the differences of dietary and non-dietary factors in hypertension and normal blood pressure (BP) of Chinese urban people. Two cross-sectional population surveys were carried out in Tianjin, one of the three largest cities in China. A total of 2068 subjects aged 35-64 years were selected by a random stratified cluster sampling, 367 men and 395 women were hypertensive, and 623 men and 683 women had normal BP. The diet was assessed by food weighing plus consecutive individual 3-day food records. Health status, health behaviours and anthropomentry were assessed. The whole population had a high sodium and low potassium consumption level. Hypertensive men and women had significantly higher daily dietary sodium intake (P < 0.05) and hypertensive women had higher dietary sodium-to-potassium ratio (P < 0.01) than men and women with normal BP. Age, body mass index, overweight and family history of hypertension were positively related to high BP. dietary sodium intake and dietary sodium-to-potassium ratio were positively associated with high BP. Education level in women and commuting physical activity in men were inversely associated with high BP.
