**Total sample size for analysis 6375, variables unknown drinking status (n= 225) and unknown physical activity (n= 97) were excluded from final analysis due to small sample size. A sensitivity analysis with the variables included showed no difference in outcomes.

***Data sources National health interview survey 2002, weighted percents extrapolated from the to the U.S. census (2000) for the adult civilian, non-institutionalized household population.
