^a All models were adjusted for area of residence to account for oversampling from rural areas. Illicit drug use, private health insurance, and household income were entered into all models. Illicit drug use and private health insurance were not significant in any of the models and household income was not significant in Models B and C.
^b All women that also completed 2006 survey regardless of pregnancy/breastfeeding status.
^c Only women who were not pregnant or breastfeeding at the 2006 survey.
