  1. Notes: bf = buffer eb = antilogarithm of regression coefficient; 95% CI = 95% confidence intervals. All analyses were adjusted for respondents’ age, gender, marital status, educational attainment, employment status, administrative-unit socio-economic status, study city, accelerometer wear time, time of the day, day of the week, and employment status by time of the day by time of the week interaction. eb is to be interpreted as the proportional increase in physical activity associated with a 1-unit increase in the predictor. a p < .05; b p < .01; c p < .001.
