Ns are unweighted. Percentages are weighted.

¹Respondents with no lifetime partners (n=244) or no partners in the past year (n=142) were coded ‘no.’

OR=odds ratio. DK=don’t know

Unadjusted ORs from bivariable models. Adjusted ORs from models controlling for all sociodemographic, behavioral & health variables in Tables 1a & 2.

²Low level of education=less than a high school degree or, among those younger than age 20, being two or more years behind in school
