  1. Note: Table presents spearman correlation coefficients for male and females. Coefficients for females are presented in parenthesis. *p < .05; **p < .01 All variables are on an interval or ordinal scale, ranging from low to high scores e.g. low mean sitting time to high mean sitting time); low job grade (other/Administrative) to high job grade (senior civil servant); low education (school certificate) to high education (higher degree).
