This study aimed to estimate mean daily sitting-time and to identify correlates of sitting-time in adults living in the urban area of Ribeirão Preto-SP, in 2006. A cross-sectional population-based epidemiological study was carried out using three-stage cluster sampling. From a sample of 1,205 individuals, 930 attended the interviews. The variability introduced in the third sampling fraction was corrected by attributing sampling weights taking into account the non-response rate and the number of eligible units in each household, resulting in a weighted sample of 2,197 participants. To identify sitting time correlates, multiple linear regression models were used. The design effect was considered when calculating all estimates. The reported overall mean sitting-time/day was 280.9 minutes. In the multivariate analysis, the following correlates were kept in the final model: gender; years of education; smoking; metabolic waste (Mets*·min*·week-1); working/day hours, and number of familial antecedents of obesity. The results pointed out sitting-time correlates and the need for health planning related to promotion and prevention policies.
