RESUMO
In a cross section study performed in Rauch in 1997 we found a high prevalence of hypertension and low levels of treatment and control. To evaluate the impact of the community-based intervention activities on blood pressure (BP), we made a cohort study in 1526 inhabitants aged between 15 and 75 years in 2003. The initial study, the advice to consult the family doctor when alterations were found, the free provision of antihypertensive drugs, the press diffusion of the study results and a healthy lifestyle were included among the intervention activities. BP was measured in the subjects' residence by especially trained nurses, considering systolic BP (SBP) and diastolic BP (DBP) as the average of three measurements in one occasion. A total of 1307 subjects (85.65%) were re-interviewed. SBP decreased from 137.98 +/- 0.57 to 132.49 +/- 0.53 mm Hg (p < 0.01) and DBP from 88.73 +/- 0.38 to 81.87 +/- 0.33 mm Hg (p < 0.01). Pressure decrease was observed in all the age groups, in both sexes and in the subgroup without receiving antihypertensive drugs. The percentage with antihypertensive drugs increased from 12.2 to 20.4 (p < 0.01). A significant relationship was observed between the percentiles of the BP changes and weight changes in subjects with and without antihypertensive drugs. Community-based intervention strategies were effective to BP control and, probably, to decrease the cardiovascular risk in a community with high prevalence of hypertension.

RESUMO
We conducted a study in a random sample of 1523 inhabitants (15-75 years old) of Rauch city to determine risk factors prevalence to development hypertension and cardiovascular diseases. We measured blood pressure, weight, height, waist circumference, cholesterol and glucose levels, sodium excretion, and alcohol and tobacco consumption. We found a high prevalence of hypertension (43.20 per cent in men and 28.50 per cent in women), and obesity-overweight (54.81 per cent in men and 44.65 per cent in women), both of them augmented with aging. Only 4 per cent of hypertensive subjects were being controlled and only 32 per cent of them were aware of their condition. Men showed a marked increment of prevalence of hypertension and obesity-overweight between groups of 15-24 years and 25-34 years. Women had delayed and more gradual increments. In male and female respectively, the prevalence of hypercholesterolemia was 26.86 and 13.81, the prevalence of diabetes was 3.42 and 1.53, and the prevalence of tobacco consumption was 34.61 and 20.83. Higher BMI and waist circumference identified subjects with higher blood pressure up to 54 and 65 years, in men and women, respectively. Age and waist circumference in the whole group, and alcohol consumption in men, were independently correlated with blood pressure; sodium excretion had no correlation. High prevalence of hypertension and obesity-overweight and their association suggest that the most important primary prevention measure in this community should be to prevent obesity. Low levels of awareness indicate the need of ongoing detection programs, and low grade to control of hypertension could be modified with education programs for health providers. (Au)
