^*Statistically significant estimates at α = 0·05 are indicated.

^†Numbers may not sum to group totals due to missing data.

^‡All percentages are weighted.

^§Chi-square tests were used for sex, race/ethnicity, vigorous recreational activity, moderate recreational activity, sedentary time, smoking, HH respondent education and HH respondent marital status. Simple linear regressions were used for age and income-to-poverty ratio.
