Psychosocial and Environmental Correlates of Sedentary Behaviors in Spanish Children.

. To evaluate children's psychosocial and environmental factors associated with sedentary behavior (SB). . The study involved a total of 420 children (mean 9.2 years; 52.9% girls) from the community of Madrid, Spain. SB and physical activity (PA) were objectively measured using accelerometers. TV viewing and potential correlates were assessed by questionnaire. Mixed-model regression analysis, adjusted for clustering within school locations, evaluated the relation of each independent variable with SBs. . Girls showed higher levels of SB than boys, whereas boys reported more TV viewing ( < .001 in all cases). Regression analysis showed that MVPA levels were negatively related to objective SB measurement in both boys and girls ( < .001). Parent and friend support to PA were negatively associated with SB on weekdays in boys and girls, respectively ( < .05). In the boys' group, parental professional level was a positive predictor of SB on weekend days ( = .011). Boys with more positive neighborhood perceptions spent less time watching TV ( < .001), whereas mother's leisure-time PA level was a negative correlate of TV viewing in girls' group ( < .01). . Different psychosocial and environmental correlates of SB were identified. Present findings are promising targets for interventions to improve children's health.
