PITANGA, F.J.G. et al. Patterns of physical activity in different domains and diabetes absence in adults. Motri. [online]. 2010, vol.6, n.1, pp.5-17. ISSN 1646-107X.

The objective was to analyse the patterns of physical activity (moderate and vigorous walking) in different domains (work, commuting, household, leisure time) as predictors of absence of diabetes. This was a cross-sectional study in the city of Lauro de Freitas, Bahia, Brazil, with a sample of 522 individuals, 57.8% of them female, over 18 years of age. Receiver Operating Characteristic curves (ROC) were constructed and compared to patterns of physical activity in differing domains and absence of diabetes. Cut-off points of physical activity (minutes/week) were established to predict the absence of diabetes. A 95% confidence interval was considered to find the largest areas under the ROC curves for leisure time physical activity and for the differing domains analysed altogether. Walking was not a good predictor of diabetes absence. Accumulated physical activity in different domains (185 minutes/week of moderate intensity or 285 minutes/week of moderate or vigorous intensity walking) presented the best cut-off points for predicting the absence of diabetes. Practicing physical activity, especially leisure time or accumulated in different domains, contributes to diabetes prevention.
