• Abstract:

  Objectives: To verify the association between body mass index (BMI) and bone mineral density (BMD) in an isolated population from a city in the interior of Rio Grande do Sul - Brazil. Methods: Cross-sectional study with patients who underwent densitometry through dual energy X-ray absorption (DEXA). Data were collected at a private diagnostic imaging clinic located in a city in the interior of the state of Rio Grande do Sul. BMI was calculated according to the World Health Organization (WHO). The BMD assessment was performed by DEXA and classified according to the WHO. The bone sites analyzed were the total lumbar spine and the hip (femoral neck and total femur). Statistical analysis was performed using prevalence ratios (PR) and their respective 95% confidence intervals for the factors under study. Results: data from 998 patients were collected and only female data were analyzed, totaling 975 patients, with a mean of 60.98 years. The eutrophic population has 1.63 times the prevalence of osteopenia compared to the obese (PR=1.63; 95% CI 1.17-2.26). Regarding Osteoporosis, in the eutrophic group, the PR was 1.89 times the PR of the obese (PR=1.89; 95% CI 1.33-2.70) and 2.39 in the Overweight group in relation to the category obese (PR=2.39; 95% CI 1.39-4.12). Conclusion: The obese population has a lower prevalence of osteopenia compared to eutrophic, as well as a lower prevalence of Osteoporosis compared to both eutrophic and overweight.
