Original Article Santos et al. Arterial hypertension in quilombola communities Arq Bras Cardiol. 2019; 113(3):383-390 In the univariate logistic regression analysis, the risk factors associated with arterial hypertension were: smoking (p = 0.02) and BMI (p = 0.04). In the multivariate analysis, the the odds ratio with statistical significance for arterial hypertension were found for the predictors age and BMI. For systolic arterial hypertension alone, the only significant statistic preditor was age; as for diastolic arterial hypertension, the predictors were age, BMI and, primarily, economic class (Table 3). The logistic regression model enabled us to identify the probability of developing arterial hypertension through increased BMI. Among the sexes, the number of women was higher. According with the age and sex, it was noticeable that, as the quilombola population grows older, the number of hypertensives tends to increase, especially among women (Figure 1). The Hosmer-Lemeshow test showed good adjustment/ calibration of the final model (p = 0.14). To assess the discrimination capacity of the model, the C-statistics was performed through calculation of the area under the ROC curve, presenting a value equal to 0.77, which was considered a satisfactory value.
