Currently, chronic noncommunicable diseases occupy priority space in healthcare. In 2007, approximately 72% of the deaths occurred in Brazil were attributed to these diseases. This study aims to estimate the prevalence of some risk factors for chronic noncommunicable diseases in adults living in the municipality of Alta Floresta, Mato Grosso state, Brazil. This is a population-based cross-sectional study with 292 adults. Obesity was classified according to the standardization of the World Health Organization (BMI ≥ 30kg/m 2). All individuals with blood pressure ≥ 140/90mmHg and/or those who reported the use of antihypertensive medication were considered hypertensive; while those who reported having no physical activity during leisure time were considered sedentary. Alcohol consumption was expressed in grams of ethanol, considering consumption above 30g and 15g per day as risk values for men and women, respectively. Individuals who reported smoking cigarettes at the time of the survey were considered smokers. The risk factor with the highest prevalence was sedentary leisure. Men showed higher percentages for smoking and alcohol consumption, while women did for obesity. Hypertension and obesity were the most prevalent risk factors in the older age group.

Study Design: Cross-sectional. Objective: Estimating the prevalence of hypovitaminosis D in a group of severely obese subjects referred to bariatric surgery. Methods: This study evaluated severely obese patients aged ≥18 years assisted by a specialized team in bariatric surgery. Clinical, anthropometric, and laboratory data were obtained from patient records. Plasma 25 (OH) D was determined by chemiluminescence and levels ≤ 20 ng/mL was considered as Hypovitaminosis D. The data were analyzed using the Statistical Package for Social Sciences® (SPSS) 20.0. Variables were described using descriptive statistics. For the comparison of the three groups, ANOVA, Kruskal-Wallis, and Pearson's chi-square tests were used. Spearman correlation test was performed to assess correlations between 25(OH)D and the other variables. P-values <0.05 were considered to be significant. Results: The study included 400 individuals, 71% were female with the mean age (SD) and BMI (SD) of 35.6 (9.1) years and 41.4 (5.1) kg/m², respectively. The vitamin D ranged from 4.5 to 62.4 ng/mL and the mean (SD) was 24.7 (7.9) ng/mL. In this sample, 117 (29.3%) individuals had hypovitaminosis D. There was a negative correlation between 25(OH)D and BMI (r= -0.110; p=0.028) and parathormone (r= -0.152; p=0.006) and positive correlation with serum calcium (r= 0.132; p=0.013) and phosphorus (r= 0.116; p=0.027). Conclusion: Severely obese subjects had a high prevalence of hypovitaminosis D even living in a sunny state.
