A 5-year follow-up study of hypertension in a rural community.
A follow-up study of hypertension was carried out among adults, in the age group between 25 to 64 years, in a rural population of Gurgaon district, Haryana, five years after an initial community based epidemiological survey of the same population. The progress of 77 out of 98 hypertensives detected at the initial survey could be reassessed. The treatment and severity of hypertension found at the initial survey has been compared with that observed on follow-up. The percentage of cases with blood pressure (BP) controlled on treatment increased from 2.6 percent to 45.4 percent on follow-up. An electrocardiogram could be obtained in 66 out of 77 subjects reexamined and was abnormal in 21 cases (31.8%). The electrocardiographic abnormalities found were: myocardial infarction in one, left ventricular hypertrophy in 5, left ventricular hypertrophy with ischaemic ST-T changes in 6, isolated ST-T abnormalities in 5 and conduction defects or arrhythmias in 4 cases. In a cohort of 1,334 subjects who were normotensive at the initial survey, 19 new cases were detected to have hypertension. The overall annual incidence of hypertension was 2.8/1000 (male: 3.8/1000 and female: 2.4/1000). In these hypertensives, a family history of hypertension was present in 10.5 percent and obesity in 42.1 percent.
