Awareness, knowledge, and misconceptions of adolescents and young people regarding long-acting reversible contraceptives: a systematic review and meta-analysis

To assess the awareness, knowledge, and misconceptions of young people regarding long-acting reversible contraceptives (LARCs).We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines of MEDLINE-Ovid, Embase, and Cumulative Index to Nursing and Allied Health Literature. A random-effects meta-analysis was performed with formal tests for heterogeneity and publication bias. Additional outcomes were summarized using thematic analysis.Not applicable.Adolescents and young adults (aged 12-25 years) with a uterus.Not applicable.Patient-reported outcomes related to awareness, knowledge, and misconceptions of LARCs (including intrauterine devices, subdermal implants, and injections) were analyzed.Of the 4,077 database citations, we included 40 studies encompassing 10,470 adolescents and young people. Twenty studies were eligible for meta-analysis. The pooled prevalence described that only 65.0% (95% confidence interval [CI], 51-78) of participants were aware of at least 1 type of LARC (I2 = 100). The meta-regression noted that the region, risk of bias, gravidity, sexual history, previous LARC experience, and postsecondary education were not associated with awareness. There were numerous misconceptions regarding eligibility, safety, and usage. Notably, 62% (95% CI, 20-91) did not understand that LARCs could be used in nulliparous individuals, and 37% (95% CI, 21-56) believed that LARCs could cause infertility.There are notable knowledge gaps among adolescents and young people regarding LARCs, such as eligibility criteria, the reversibility of long-acting options, and misconceptions regarding infertility. Clinicians should specifically counsel regarding the suitability for LARCs in nulliparous populations and that LARCs do not cause infertility.
