2 Mean ± standard error, P-value from ANOVA models, adjusted for age, education level and baseline value of the corresponding variable (i.e. baseline: LTPA duration, LTPA score, LTPA low, moderate or vigorous intensity, leisure walking duration, time spent watching TV, BMI, or waist circumference, respectively).
