Abbreviations: CI, confidence interval; CVH, cardiovascular health.

^a Values are percentage (95% confidence interval) unless otherwise indicated. Because of survey weighting, proportions differ from calculations based on the unweighted number. Percentages may not total to 100% because of rounding.

^b Binge drinking was defined as more than 4 drinks per day for women or more than 5 drinks per day for men.

^c Mean score excluded those who were missing 1 or more CVH components.
