Abbreviations: OR, odds ratio; CI, confidence interval; MVPA, moderate to vigorous physical activity (as a continuous variable measured in hours per week)

^aSeparate models were examined for each domain of activity and for overall activity

^bAdjusted for number of children <18 in the household, anxiety, perceived stress

^cAdjusted for race/ethnicity, education, perceived stress

^dAdjusted for age, perceived stress

^eAdjusted for education

^fAdjustment for covariates did not alter the estimates by ≥10% for transportation MVPA. Only unadjusted estimates are reported.

^gAdjusted for race/ethnicity, body mass index, perceived stress

^hAdjusted for age
