Predictors of long-acting reversible contraception use among unmarried young adults

ObjectiveThe objective of the study was to improve the understanding of long-acting reversible contraception (LARC) use patterns among unmarried, young adults at risk of unintended pregnancy.Study DesignWe performed a secondary data analysis of a national survey conducted by Guttmacher Institute of unmarried women and men aged 18-29 years. LARC is defined as an intrauterine device (IUD) or implant. Predictors of LARC use and IUD knowledge among those at risk for unintended pregnancy (n = 1222) were assessed using χ2 analysis and logistic regression models.ResultsLARC use was associated with older age, high IUD knowledge, and earlier onset of sexual activity. Respondents with high IUD knowledge were 6 times more likely to be current LARC users (odds ratio [OR], 6.3; 95% confidence interval [CI], 1.4-28.8). Sociodemographic variables did not predict use. Respondents with lower education (OR, 1.76; 95% CI, 1.0-3.0), an external locus of control (OR, 1.6; 95% CI, 1.1-2.3), male sex (OR, 2.8; 95% CI, 1.9-4.1), and foreign language had less knowledge of IUD.ConclusionIncreasing knowledge of IUD among certain groups may improve LARC use among young, unmarried adults and in turn decrease unintended pregnancy.
