|Multiple regression results of the subjects according to barrier domains and as a whole (n = 730)|
|Barrier domain||Predictor (s)||β coefficient||p value (predictor)||R2 (model)||p value (model)|
|Personal||Physical activity status||−0.215||<0.001||0.087||<0.001|
|Social environment||Physical activity status||−0.152||0.002||0.037||0.001|
|Physical environment||Educational level||−0.132||0.011||0.061||<0.001|
|Physical activity status||−0.130||0.008|
|Monthly household income||−0.112||0.031|
|Overall||Physical activity status||−0.210||<0.001||0.085||<0.001|
Note: Beta-coefficient (β) was used to describe to describe the extent of SD change in the physical activity barriers score if the predictor of interest changed by 1 SD (while the other predictors were held constant). R2 was used to describe the variation of barriers score
*significance level at p < 0.05.
