title: Blood pressure profile, urinary sodium and body weight in the 'Oraon' rural and urban tribal community.
abstract: Blood pressure and nutritional profiles in the 'Oraon' tribal community of India living in rural and urban areas were studied between 1981-85 after a house to house survey of 4523 rural tribal people (RT) and 935 of their urban tribal counterparts (UT). Prevalence of hypertension was found to be 4.8/1000 males and 4.3/1000 females in rural tribal group giving an overall rate of 4.6/1000. In contrast the same were 27.1/1000 males and 21.4/1000 females in UT group, overall rate being 25.6/1000. Average calorie consumption were 1750 and 2280 and mean 24 hour-urinary sodium excretions 58 and 118 milliequivalents in RT and UT groups respectively. Of the total of 21 subjects in RT and 24 in UT detected to be hypertensive, 7 had common family inheritance. Increased mean arterial pressure correlated with increased sodium consumption and body weight. Hypertensives from both the groups showed higher urinary sodium excretion (P < 0.05). This epidemiologic study proves the role of a genetic factor/defect complicated by higher salt consumption in causation of increased blood pressure.
