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
BMI 0.180 <0.001
Marriage status −0.101 <0.001
Social environment Physical activity status −0.152 0.002 0.037 0.001
BMI 0.112 0.024
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
BMI 0.146 0.003
Educational level −0.110 0.023

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.
