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% in men and 28.50% in women), and obesity-overweight (54.81% in men and 44.65% in women), both of them augmented with aging. Only 4% of hypertensive subjects were being controlled and only 32% 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.
