Multivariate linear mixed models, adjusted for context-specific wear time, age, meteorology, social economic status of the neighborhood, and nested structure of days within children and children within schools. Dependent variables are log-transformed and independent variables were standardized. -: Variable not statistically significant and therefore not part of final multivariate model. 1 -2 log likelihood= 669.3; 2 -2 log likelihood= 992.6; 3 Unstandardized coefficients represent the relative area of that variable, as a percentage of a child’s total activity space.
