A Cost Effectiveness Model of Long-Acting Reversible Contraceptive Methods in the Brazilian National Health System

Cost Savings and Effectiveness of Long-Acting Reversible Contraception (LARC) on the Prevention of Pregnancy in Adolescents: A Systematic Review

Adolescent pregnancy is a major public health issue with profound implications for health and socioeconomic factors. The use of long-acting reversible contraception (LARC) could be an interesting strategy to reduce the unintended pregnancy rate. However, the cost of LARC is still a barrier to widespread adoption. This study aimed to analyze the effectiveness and economic impact of LARC compared with non-LARC methods in preventing unintended pregnancy among adolescent girls. This systematic review was registered in PROSPERO (CRD42023387735) and conducted following the PRISMA guidelines. We included articles covering adolescents aged 10-19 years without language restrictions that evaluated the use of LARC compared with non-LARC in terms of effectiveness and the public health costs of unintended pregnancy. The search for articles included the databases MEDLINE/PubMed, Cochrane Library, Embase, and Lilacs, using the entry terms "Adolescent" and "Long-Acting Reversible Contraception." We evaluated the risk of bias and the certainty of the evidence for each outcome of interest. The search retrieved a total of 1,169 articles and, after the title and abstract, we identified 40 articles for full-text analysis. Out of the 40 studies evaluated, 4 articles met the eligibility criteria for cost evaluation, and 1 met the eligibility criteria for effectiveness as an outcome. In conclusion, LARC emerges as the most effective and cost-effective contraceptive method. The cost of utilizing LARC, especially the copper IUD, is significantly lower than the costs attributable to unintended pregnancies in adolescence.

Subdermal contraceptive implants and repeat teenage motherhood: Evidence from a major maternity hospital-based program in Uruguay

Teenage fertility is a social problem because of its private and public costs in countries of different development levels. Reductions in adolescent birth rates do not necessarily follow drops in overall fertility due to the demographic transition model. This paper analyses the impact of a subdermal contraceptive program on repeat teenage motherhood. Using a regression discontinuity design, we find that the intervention reduced mothers' likelihood of having another child in the next 48 months by 10 percentage points. This reduction is not random, and we also identify small positive selection in subsequent births.

Low Use of Long-Acting Reversible Contraceptives in Tanzania: Evidence from the Tanzania Demographic and Health Survey

We aimed to determine the prevalence and factors associated with the use of long-acting reversible contraceptives (LARCs) among women of reproductive age in Tanzania. We analyzed the Tanzania Demographic and Health Survey (DHS) data from 2015 to 2016. The study included 8189 women aged 15–49 years. The relationship between various factors and LARC use was determined through various analyses. Among women with a partner/husband, 7.27% used LARCs, 21.07% were grand multiparous, and 20.56% did not desire more children. Women aged 36–49 years (adjusted odds ratio (AOR)-2.10, 95% confidence interval (CI): 1.11–3.96), who completed secondary education (AOR-1.64, 95% CI: 1.05–2.55), who did not desire more children (AOR-2.28, 95% CI: 1.53–3.41), with a partner with primary level education (AOR-2.02, 95% CI: 1.34–3.02), or living in richer households (AOR-1.60, 95% CI: 1.12–2.27) were more likely to use LARCs. Further, women with a partner who wanted more children were less likely to use LARCs (AOR-0.69, 95% CI: 0.54–0.90). Tanzania has a low LARC usage rate. Women’s age, wife and partner’s education status, couple’s desire for more children, and household wealth index influenced the use of LARCs, highlighting the need to reach more couples of lower socioeconomic status to improve LARC utilization.
