  1. Notes: Percentages and means are based on weighted and unadjusted data. P values for overall group comparison based on χ2 tests. All P values <0.001, except age between overweight and obese (<0.05). Differences in number of dependents between overweight and obese were non-significant. Differences among groups based on metropolitan area residency and whether spouse held a job with EBHI were non-significant. Column totals may not add up to 100 due to rounding.
