2012
Abstract Objective We studied associations between social disadvantage and indicators of sedentary behavior and physical activity at preschool age. Methods Data from 4688 children enrolled in a birth cohort in Rotterdam, the Netherlands, between 2002 and 2006 were analyzed. Indicators of sedentary behavior (watching television ≥ 2 h/day and sitting in a buggy ≥ 0.5 h/day) and physical inactivity (playing outside Results Children with low-educated mothers (OR: 3.27, 95% CI 2.12–5.05) and non-Dutch children (OR nonWestern : 2.67, 95% CI 2.04–3.49, OR Western : 2.09, 95% CI 1.42–3.0) were more likely to watch television for at least 2 h/day. Similar results were seen for sitting in a buggy for at least 0.5 h/day. Non western children were more likely to play outside for less than 3 h/day (OR: 1.95, 95% CI: 1.39–2.73) than native Dutch children, while no differences were seen for other western children or children from mothers with a low educational level. Conclusions Socio-economic status and ethnicity are already associated with indicators of sedentary lifestyles at preschool age.
