Notes: LS1 = Single Abstinent Women; LS2 = Consistently Covered Mothers; LS3 = Stable Users; LS4 = Sexually Active Nonusers; LS5 = Condom Users; LS6 = Intermittent Users; and LS7 = Transient Users. Probabilities were calculated from multinomial logistic regression models controlling for age, education, federal poverty level, race and ethnicity, and religion. All n entries are set in boldface to differentiate them from the probabilities.
