Regression analyses for possible mediators of the associations between physical/social environmental perceptions and mental health-related quality of life.

SE = standard error; CI = confidence interval; MVPA = moderate-to-vigorous physical activity.
Note 1: α–coefficients were estimated by regressing the potential mediators onto the physical/social environmental perceptions.
Note 2: β-coefficients were estimated by regressing mental health-related quality of life onto the physical/social environmental characteristics and potential mediators.
Note 3: αβ-coefficients represent the mediated effect.
Note 4: all possible mediators were positively scored (higher score = more physical activity).
Note 5: all analyses were adjusted for individual-level BMI, marital status, smoking status, educational level and employment status, work-related and household-related total physical activity.
