大和高原三村における住民健診受診者の血圧値および血清脂質の推移 ： 1987年度から1991年度の連続受診者649名の解析

Abstract

Chronological changes in blood pressure and serum lipid levels were investigated in the people (232 men and 417 women) participating in annual community-based mass examinations which were carried out from 1987 to 1991 in three villages in the northern part of Nara Prefecture. The results obtained are summarized as follows ; 1) Around 40% of the people participating in the mass examinations in each year attended the examinations annually from 1987 to 1991. 2) Fourteen percent of men participating in the examinations annually had medical treatment for some kind of disease, of which 47% was hypertension. The corresponding figures for women were 16% and 70% respectively. 3) Prevalence of people judged to be hypertensive at the time of mass examinations decreased chronologically from 1987 to 1991. 4) Prevalence of the hypertensive people including under treatment for hypertension decreased chronologically in men, but increased in women. Prevalence of women with good controlled blood pressure increased chronologically. Among the hypertensives, prevalence of the persons without any treatment was the highest among men of their 50s. 5) Mean serum total cholesterol levels of both men and women were significantly higher at the last examination than the first one. 6) Serum HDL cholesterol levels showed no significant chronological change.
