*Sample size for accelerometer variables 229 for SEP 1 and 2; 103 for SEP 3; 247 for SEP 4 and 5.
†χ² was used to test significance of association between categorical variables and SEP score.
‡ANOVA was used to test significance of association between continuous variables and SEP score.
ANOVA, analysis of variance; BMI, body mass index; MVPA, moderate-to-vigorous physical activity.
