Notes: ANCOVA models were fitted with Generalized Linear Model procedure in Stata, version 13. Analyses were adjusted for complex survey design, sex, age, self-reported usual daily physical activity (usually sit versus others), education and household income. Model-based coefficients (b) show relationship between physical activity and health-related measures and weekly hours of utilitarian walking; for example, compared with those who reported walking less than 1 hour per week, those who reported more than 5 hours per week accumulated an additional 9.3 minutes of moderate-to-vigorous activity per day. Moderate-to-vigorouss physical activity data were square root-transformed for analyses; C-reactive protein and triglycerides were log-transformed (non-transformed coefficients are provided for ease of interpretation, but p-values were calculated with the transformed data).
