Dual use of condoms with other contraceptive methods among adolescents and young women in the United States.
OBJECTIVE
To estimate the prevalence of and factors associated with dual method use (i.e., condom with hormonal contraception or an intrauterine device) among adolescents and young women in the United States.


METHODS
We used 2006-2010 National Survey of Family Growth data from 2,093 unmarried females aged 15-24 years and at risk for unintended pregnancy. Using multivariable logistic regression, we estimated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to assess the associations between dual method use at last sex and sociodemographic, behavioral, reproductive history, and sexual behavior factors.


RESULTS
At last sex, 20.7% of adolescents and young women used dual methods, 34.4% used condoms alone, 29.1% used hormonal contraception or an intrauterine device alone, and 15.8% used another method or no method. Factors associated with decreased odds of dual method use versus dual method nonuse included having a previous pregnancy (aOR = .44, 95% CI .27-.69), not having health insurance coverage over the past 12 months (aOR = .41, 95% CI .19-.91), and having sex prior to age 16 (aOR = .49, 95% CI .30-.78).


CONCLUSIONS
The prevalence of dual method use is low among adolescents and young women. Adolescents and young women who may have a higher risk of pregnancy and sexually transmitted infections (e.g., those with a previous pregnancy) were less likely to use dual methods at last sex. Interventions are needed to increase the correct and consistent use of dual methods among adolescents and young women who may be at greater risk for unintended pregnancy and sexually transmitted infections.
