Abstract
Few studies have reported on risk factors by blood pressure categories based on antihypertensive treatment in the general population. We examined the associations between blood pressure categories and other risk factors in Japan. Cross-sectional study, multicenter population-based study was designed. A total of 11,302 men and women were eligible. Data were obtained from April 1992 to July 1995 in 12 rural districts in Japan. Subjects were divided into three categories: normotensives (with blood pressure <140/90 mmHg), treated hypertensives (antihypertensive treatment regardless of current blood pressure), and nontreated hypertensives (blood pressure ≥140/90 mmHg without hypertensive treatment). The proportions of normotensives, treated hypertensives, and nontreated hypertensives were 63%, 10%, and 27% among men, and 67%, 13%, and 20% among women, respectively. Total cholesterol, triglyceride, blood glucose, and body mass index were higher in treated or nontreated hypertensives than in normotensives. Fibrinogen, factor VIIc, and physical activity index were higher in treated hypertensives than in normotensives. High-density lipoprotein (HDL) cholesterol was higher in normotensives than in treated or nontreated hypertensives in women; but no tendency was shown in men. The proportions of dyslipidemia, impaired glucose tolerance, and metabolic syndrome were significantly higher in treated and nontreated hypertensives than in normotensive men and women. In conclusion, cardiovascular risk factors were higher in hypertensives with or without treatment than in normotensives in a general population in Japan.
