Abstract:

This study sought to investigate the effect of race on measures of body fat (body mass index - BMI, waist circumference - WC and waist-hip ratio - WHR), as well as its relationship with diabetes, among elderly individuals living in urban areas in seven places in Brazil, according to gender. This is a cross-sectional study carried out with a probabilistic sample comprising 2,566 individuals with 65 years of age or more who participated in the FIBRA Study (Frailty in Elderly Brazilians). We used several self-reported sociodemographic variables (gender, age, race, schooling and family income), anthropometric measures of general (BMI) and abdominal obesity (WC and WHR) and self-reported diabetes. Adjusting for schooling and income, white race was associated with higher WC values (p = 0.001) and WHR (p > 0.001) for male gender, regardless of diabetes status. However, when we considered only diabetic individuals, black race became associated with general (BMI) (p = 0.007) and central obesity (CC) (p > 0.001), only among women.
