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

Objective The 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 Design We 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. Results LARC 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. Conclusion Increasing knowledge of IUD among certain groups may improve LARC use among young, unmarried adults and in turn decrease unintended pregnancy.
