Nutritional risk in the urban population of Ouro Preto, southeastern region of Brazil: the Ouro Preto heart study.
OBJECTIVE
To estimate the prevalence of combined nutritional risk according to sociodemographic and sedentarism characteristics of the urban population of Ouro Preto, state of Minas Gerais, Brazil.


METHODS
This cross-sectional study was conducted with a probability sampling of 768 subjects aged 15 years or older. Nutritional risk (NR) was defined according to the BMI and WC classification criteria adopted by the National Institutes of Health. Isolated NR (INR) was defined as women with WC > 80 cm and men with WC > 94 cm, and the combined nutritional risk (CNR) as the same WC values mentioned above and/or BMI > 25 kg/m(2). Binary logistic regression and the Hosmer & Lemeshow test were used to construct and adjust these models.


RESULTS
INR was observed in several BMI categories for both women and men, with the following results: 19.1% and 1.4% among those with normal weight, 91.7% and 56% in overweight patients, and 98.5% and 80% in obese patients, respectively. Age and level of education were independently associated with the CNR. Odds ratios (OR) for CNR in women and men over 60 years of age were 9.94 and 14.35, respectively, when compared to younger patients. For women with < 4 years of schooling, the OR was 1.83 compared to patients with more than 4 years of school attendance, while among men with an average number of years of school attendance, the OR was 2.55 relative to those with more years of schooling.


CONCLUSIONS
These findings show that age and education have an independent effect on the probability of CNR occurrence, and also that a joint analysis of BMI and WC is important in screening groups for nutritional risk.
