[The incidence of hypertension and associated factors among middle aged workers and farmers in Beijing and Guangzhou].
3347 males and 3927 females aged 35-54 with normal blood pressure (not on antihypertensive medication) at entry were followed up for 4 years. The incidence of hypertension and associated factors were analyzed. There was a significant difference in incidence of hypertension between southern and northern population of China (2-5 times). The age-adjusted 4 year incidence of definite hypertension in Beijing male and female workers were 6.8% and 4.1% respectively, but only 0.7% and 2.1% respectively in Guangzhou, while in Beijing farmers were 10.1%, 5.0%, and in Guangzhou farmers were 2.3%, 0.5% respectively. The results also showed incidence of hypertension were significantly correlated with body mass index (BMI). BMI greater than or equal to 24 group had higher hypertension incidence than BMI less than 24 (2.1-3.2 times). Alcohol intake was correlated to hypertension incidence rather than nonalcoholics. But no significant relations were found with smoking, educational level and the intensity of physical labour.
