Association of Chronic Disease With Sedentary Behavior in a Rural Community-Dwelling of Older Men from Southern Brazil
METHODS:
This is a cross-sectional, population-based household survey carried out in the county of Antônio Carlos, Southern Brazil (2010-2011). A total of 207 older men aged ≥ 60 years (random sample) were interviewed, and 202 participated in this study. Those women who were bedridden or non-ambulatory were not included in the analysis. Sitting time (questionnaire) identified sedentary behavior (≥ 6 hours/day). The chronic diseases included (self-report): hypertension, diabetes, cancer, pulmonary disease, coronary heart disease, stroke, osteoarthritis/rheumatic diseases, depression, osteoporosis, history of falls. Crude and adjusted analyzes (4 models) were carried out using Poisson regression; prevalence ratios (PR) and 95% confidence intervals (CI) were calculated.
RESULTS:
Mean age of participants was 73.3 ± 8.9years, and 45.5% of them showed sedentary behavior. According crude analyzes, hypertension, diabetes, cancer, and osteoarthritis/rheumatic diseases were associated with sedentary behavior. In the final model, after adjusting (age, schooling, living arrangements, smoking, alcohol consumption, waist circumference, disability, cognitive status, and all other chronic diseases), the associations between diabetes (PR 2.26; 95%CI: 1.35-3.38) and osteoarthritis/rheumatic diseases (PR 1.16; 95%CI: 0.89-1.51) with outcome remained significant. In addition, older men with cancer (PR 0.38; 95%CI: 0.16-0.62) and osteoporosis (PR 0.51; 95%CI: 0.29-0.89) showed lower prevalence of sedentary behavior.
CONCLUSIONS:
Diabetes and osteoarthritis/rheumatic diseases were associated with sedentary behavior whereas cancer and osteoporosis were inversely associated with the outcome. These associations occurred even when co-morbidity and other confounding factors were taken into account.
