Prevalence of hypertension and risk factors in Sinop city (Mato Grosso/Brazil)

Hypertension is a chronic disease considered an important risk factor to high level of morbidity and mortality in the world. The objective was to evaluate the prevalence of hypertension and cardiovascular risk factors in Sinop (MT/Brazil). This cross-sectional study was conducted in 2014 between February and November. Data collection included self-reported behavioral risk factors and clinical measurements comprising blood pressure and anthropometry, totaling 649 adult subjects. The prevalence of hypertension was 39%, being higher in men (23%) than women (16%). Overall, 33.4% were obese and 39.9% were overweight; 12.5% smoke one or more packs of cigarettes per day; 68.9% were sedentary; 50.5% demonstrated altered waist/hip ratio; 22.8% and 50.8%, respectively, presented high and very high cardiovascular risk by waist circumference measure. Odds ratio analyses demonstrated that hypertension was associated with male subjects, increased age, excess weight and high waist/hip ratio as well altered waist circumference. This study showed high prevalence of hypertension, overweight and obesity in Sinop/MT. In addition, many hypertensive patients under anti-hypertensive treatment showed uncontrolled blood pressure levels. There was a significant association between hypertension and age, gender, body mass index, waist circumference and waist/hip ratio.
