Long-acting removable contraceptives prevent teen pregnancy

Current evidence of contraceptive uptake, pregnancy and continuation rates in young women: a systematic review and Meta-analysis

OBJECTIVE

Half of all pregnancies worldwide are unintended, and the rate is even higher in women aged ≤25 years. We sought to identify which method of contraception was the most effective option to prevent unintended pregnancy in young women and adolescents.

METHODS

Systematic searches, without language restrictions, were carried out of the PubMed, Embase, Lilacs and Cochrane databases from inception to July 2020. Abstracts and full-text articles of observational studies and randomised controlled trials comparing the use of multiple methods of long-acting reversible contraception (LARC) and short-acting reversible contraception (SARC) in young women and adolescents were screened and reviewed. Risk ratios (RRs) and mean differences with their 95% confidence interval (CI) were derived using a random-effects meta-analytical model. Meta-analyses provided pooled estimates for adverse events, continuation rates and efficacy of LARC methods in young women and adolescents. Nine of the 25 included studies compared LARC with SARC, and 16 compared LARC methods only.

RESULTS

At 12 months, young women had better adherence with LARC compared with SARC (n = 1606; RR 1.60; 95% CI 1.21, 2.12; I ² = 88%), which suggests a better unintended pregnancy prevention outcome for young women. However, more young women chose SARC (n = 2835; RR 0.37; 95% CI 0.17, 0.80; I ² = 99%). Pregnancy during LARC use was rare.

CONCLUSION

LARC methods are the most efficacious in preventing pregnancy, and women should be informed of this if pregnancy prevention is their priority. The evidence, however, is of low quality.

Pregnancy Ambivalence and Long-Acting Reversible Contraceptive (LARC) Use Among Young Adult Women: A Qualitative Study

CONTEXT

Many young adults are unclear about how much they want to have, or prevent having, a baby. However, pregnancy ambivalence is an underexamined factor in the uptake of long-acting reversible contraceptive (LARC) methods-IUDs and implants-the most effective methods available.

METHODS

In 2014, investigators conducted six focus groups and 12 interviews with 50 women aged 18-29 in Dane County, Wisconsin; participants were either university students or community residents receiving public assistance. A modified grounded theory approach was used to analyze the data.

RESULTS

Four themes emerged. First, participants described a pregnancy desire spectrum: Those strongly motivated to avoid pregnancy were most receptive to LARC methods, while those with less clear or mixed desires worried that these methods would prevent "accidental" pregnancies that might not be unwelcome. Second, women within a few years of wanting children perceived LARC methods as too "permanent," despite awareness of their reversibility. Third, age and life stage were important factors: Younger women and those attending school or beginning careers were more likely than others to consider these methods because they had clearer motivations to avoid pregnancy. Finally, relationship stage influenced receptiveness to LARC methods: Women in newer relationships were more receptive than were those in longer term relationships who imagined having a baby with their partner someday.

CONCLUSION

Effectiveness is not the only factor in women's selection and use of contraceptive methods. Individual preferences will lead some women to choose non-LARC methods even when fully informed of their options.

Beyond the Surface

Purpose: To describe rates of and reasons for follow-up among adolescents and adults receiving contraceptive implants in a Federally Qualified Health Center (FQHC). Methods: Retrospective comparison of patient-initiated implant-related contacts during the 6 months postinsertion among adolescents (110) and adults (154) who had implants placed at a FQHC network. Results: Forty percent of adolescents and 26% of adults initiated follow-up ( P = .016). Bleeding changes and discussing removal were the most common reasons for follow-up for both groups. Adolescents (5.5%) and adults (9.0%) had similar removal rates ( P = .348). However, among patients who discussed implant removal, adults were more likely to have removals compared with adolescents ( P = .002). Conclusions: Other FQHCs may anticipate a similar experience to ours, where adolescents may be more likely than adults to initiate implant-related follow up, with removal rates of less than 10% at 6 months. Further study of physician decision making and patient autonomy regarding implantable contraception removal requests is warranted.

The intimate link: a systematic review of highly effective reversible contraception and women's sexual experience

Contraception is expressly designed for nonprocreative sexual activity, but we know little about how methods shape women's sexual experience. To systematically review the literature on highly effective reversible contraception (HERC) and sexual experiences. MEDLINE, SCOPUS, and Google Scholar were searched for relevant literature. Eleven studies met the inclusion criteria; all were conducted outside of the United States. All studies reviewed found either improvements or no change in sexual experience and function outcomes with HERC use. A need exists for more prospective studies with a wider range of measures to assess HERC methods' impact on women's sexual experiences.

Exploring clinician confidence in the management of adolescent menstrual and reproductive health problems

PURPOSE

A high incidence of menstrual problems is reported in adolescent girls, with significant attendant morbidity. The majority are likely to be seen and managed by doctors other than specialist gynaecologists. This study aimed to survey the practice of doctors other than gynaecologists, to establish their chosen therapeutic options and confidence levels and to explore knowledge, using clinically challenging scenarios.

METHODS

A questionnaire designed to fulfil the above aims was distributed to a wide range of clinicians across paediatric disciplines and primary care.

RESULTS

The questionnaire was returned by 306 clinicians. General practitioners and paediatric endocrinologists were more confident in management and were more likely to self-manage patients (p < 0.01). The oral contraceptive pill was the most frequently chosen first-line therapy by all clinicians, followed by transdermal oestrogen/progesterone, etonorgestrel implant, progesterone-only pills, levonorgestrel-intrauterine system and depot medroxyprogesterone acetate injections. General, community and subspecialist paediatricians were more likely to choose suboptimal management strategies for each of five clinical scenarios.

CONCLUSIONS

Low confidence levels, suboptimal therapy choices and high referral rates are common among general paediatricians, community paediatricians and subspecialists for adolescents with menstrual and reproductive health concerns. Targeted education for these clinician groups, towards optimizing management for these patients, would enhance care.

Celebration meets caution: LARC's boons, potential busts, and the benefits of a reproductive justice approach

Recent years have witnessed an outpouring of research and funding pertaining to long-acting reversible contraception (LARC). The time is ripe to contextualize LARC’s hype within our broader reproductive health goals and tools—that is, how we can best address the needs of individuals who benefit from the reproductive health services we provide. After reviewing LARC’s major benefits, this commentary presents three potentially problematic aspects of LARC promotion: 1) the notion that increasing LARC use could singlehandedly end unintended pregnancies and their associations with poverty, 2) the clinical emphasis on LARC methods over all others, and 3) inadvertently failing to acknowledge the ways in which poor women of color will experience LARC promotion through legacies of racism and eugenics. The comment concludes by highlighting the benefits of a reproductive justice approach to LARC: an approach devoted to making LARC affordable and accessible while simultaneously respecting women’s decisions not to use LARC, their ability to have LARC removed when they wish, and their ability to determine for themselves where contraception and pregnancies fit into their lives.
