The aim of the present study was to determine the disease course of hypertensive male university students followed for 8 to 26 years (average, 17 years) after graduation. Subjects were classified into two groups. 1) A hypertensive group (H-group) consisting of 338 conclusively hypertensive male students followed from 1973 to 1990 at the Institute of Health Science, Kyushu University. Their ages ranged from 20 to 27 years, and all had high blood pressure (BP) of 140 mmHg or greater in systole (SBP) and/or 90 mmHg or greater in diastole (DBP) at a regular health check. This was confirmed by BP measurements for 3 days within 1 week. 2) A normotensive control group (N-group) consisting of 732 normotensive students (110-124 SBP/60-74mmHg DBP) for whom faculty, age, sex, height, weight, and examination period were matched to the H-group as closely as possible. In 1997, each subject was sent a questionnaire with items on height, weight, sitting BP, pulse rate, family history of hypertension, lifestyle habits (such as drinking and smoking), stress and personality type. Completing the questionnaire were 177 (52.4%) of the H-group and 206 (28.1%) of the N-group subjects. Hypertension continued in 44.6% of the H-group subjects, whereas 9.2% of the N-group subjects became hypertensive. The rate of hypertension at the end of the investigation was significantly higher in those subjects who had a family history of hypertension than in those who did not. Weight gain (+15.1%) was the highest in H-group subjects who were initially normotensive. These subjects showed a significantly higher incidence of smoking and drinking than the other subjects. These results confirmed lifestyle to be one of the most important factors in keeping BP normal throughout life and also suggested that fundamental health education should be introduced at an early age.
