This study sought to estimate the prevalence of the combination of Body Mass Index (BMI) plus Waist Circumference (WC) and of BMI plus Waist to Height Ratio (WHR) and to investigate associated factors. A two-stage random sample of adults (>20 years) living in former African slaves communities (Quilombos) was taken in Vitória da Conquista in the State of Bahia in 2011. Combined BMI+WHR nutritional risk was defined by the simultaneous presence of BMI > 25.0Kg/m2 or > 27.0Kg/m2, if aged > 60 years and WHR > 0.5. BMI + WC nutritional risk was defined by elevated BMI in addition to WC > 80cm for women, or > 94cm for men. Among the 739 participants, the prevalence of combined nutritional indicators were 35.3% (BMI + WHR) and 26.8% (BMI + WC). Female sex and hypertension increased the chances of a combination of both indicators, while being unmarried decreased the chances. The prevalence of BMI + WHR was higher in the 40-59 year age range and the prevalence of BMI + WC was higher in the 40-49 year age range. Less schooling increased the chances of the combined BMI + WHR indicator and watching television for more than two hours/day increased the chances of the BMI + WC indicator. The high prevalence of combined nutritional indicators indicate the need of diet promotion actions to prevent obesity.
