a

Adjusted Prevalence from Model 2 in non-MML states (27 non-MML states by 2013).

b

Adjusted Prevalence from Model 2 in MML states before the enactment of MML (10 states have before MML data available).

c

Adjusted Prevalence from Model 2 in MML states after the enactment of MML (21 states have after MML data available, 11 that passed MML prior to 2004 and 10 that passed MML between 2005–2013)

All models were adjusted by: Individual-level covariates: sex, race/ethnicity, population density; State-level covariates: proportion of each state’s population male, white, aged 10–24, and at least high school education in population aged >25 years, state unemployment rate and median household income.
