Background: in light of evidence linking sedentary behaviors to health outcomes, there have been calls for the measurement of sedentary behavior in surveillance studies. This study examined the convergent validity of 2 self-report measures of sitting time and accelerometer-determined sedentary time (minutes/day of .05). Sitting time was significantly underestimated using the single-item specific-day question on weekdays (-173 +/- 18 mins/day) and weekend days (-219 +/- 23 mins/day, both P < .001). Conclusions: When assessed via self-report, the estimation of total sitting time is improved by summing sitting times reported across different domains. The continued improvement of self-report measures of sitting time will be important if we are to further our understanding of the links between sedentary behavior and health.
