^*Adjusted for age (using age-standardized weights, based on the US 2000 Census Population distribution, as well as age as a categorical variable) and gender.

^†Additional adjustment for race/ethnic groups (black, Mexican American, other vs. white)

^‡Additional adjustment for smoking (now, former vs. never) and physical activity (overall moderate and vigorous activity score).
