The effect of youth-friendly health services on risk of pregnancy among adolescent girls and young women in Lilongwe, Malawi: a secondary analysis of the girl power-Malawi study.

In sub-Saharan Africa, adolescent girls and young women aged 15-24 (AGYW) experience high risk of early and unintended pregnancy. We assessed the impact of youth-friendly health services (YFHS) on pregnancy risk among AGYW who participated in the Girl Power study. In 2016, Girl Power randomly assigned four government-run health centers in Lilongwe, Malawi, to provide a standard (n=1) or youth-friendly (n=3) model of service delivery. At six and 12 months, study participants (n=250 at each health center) self-reported their current pregnancy status and received a urine pregnancy test. Because of missing pregnancy test results, we used multiple imputation to correct for outcome misclassification in self-reported pregnancy status, and applied the parametric g-formula on the corrected data to estimate the effect of YFHS on the 12-month risk of pregnancy. After correcting for outcome misclassification, the risk of pregnancy under the scenario where all health centers offered YFHS was 15.8% compared to 23.2% under the scenario where all health centers offered standard of care (risk difference: -7.3%, 95% CI: -15.5%, 0.8%). Access to a model of YFHS that integrates provider training with youth-friendly clinic modifications and community outreach activities may decrease risk of pregnancy among AGYW relative to standard of care.

Intimate Partner Violence and Contraception among Adolescent Girls and Young Women: A Longitudinal Analysis of the Girl Power-Malawi Cohort.

PURPOSE: In sub-Saharan Africa, sexually active adolescent girls and young women (AGYW) experience high rates of intimate partner violence (IPV) and low levels of contraceptive use, but the effect of IPV on contraceptive use is not well understood. METHODS: In the Girl Power-Malawi study, AGYW aged 15-24 were recruited from 4 health centers in Lilongwe, Malawi, and followed for 1 year. At baseline, AGYW were assessed for IPV using the modified Conflict Tactics Scale. AGYW reported contraceptive method use at 6 and 12 months, characterized as barrier, non-barrier, or any modern method. Modified Poisson regression was implemented to estimate risk ratios (RRs) and 95% confidence intervals (CIs) to examine the effect of IPV on contraceptive use. RESULTS: One thousand AGYW were enrolled, and 954 non-pregnant participants were included. Baseline prevalence of IPV with the most recent partner was 35.5% (physical), 46.2% (sexual), and 76.9% (emotional). Baseline IPV did not affect contraceptive use at 6 months (aRR [95% CI]: physical 0.98 [0.91-1.05]; sexual 1.00 [0.94-1.07]; emotional 1.03 [0.94-1.12]) or 12 months (physical 0.95 [0.89-1.02]; sexual 0.96 [0.90-1.02]; emotional 0.98 [0.91-1.05]). None of the 3 IPV categories affected contraceptive use when the outcome was restricted to either barrier or non-barrier methods. CONCLUSIONS: In this cohort, IPV was not a key driver of contraceptive use in longitudinal analyses. Interventions are needed to address the alarming rates of IPV in this population, but addressing IPV alone might be insufficient to address low contraceptive use, and multifaceted youth-friendly health services might be necessary.

Socioeconomic Predictors of Transactional Sex in a Cohort of Adolescent Girls and Young Women in Malawi: A Longitudinal Analysis.

Transactional sex is associated with incident HIV infection among adolescent girls and young women (AGYW) in sub-Saharan Africa. Evidence on the dimensions of socioeconomic status (SES) which predict transactional sex are mixed and primarily come from cross-sectional studies. This study examined the association between SES and transactional sex in a longitudinal cohort (n = 844) of AGYW ages 15-24 years enrolled in a quasi-experimental study in Lilongwe, Malawi. Prevalence of transactional sex was 22% at baseline, 15% at 6-months and 20% at 12-months. Being divorced or widowed, being food insecure, living in a home without electricity or running water, and having few assets were associated with transactional sex. Higher educational attainment and school enrollment were protective. Having 6-7 socioeconomic risk factors increased odds of transactional sex (AOR = 4.13, 95% CI 2.45, 6.98). Structural interventions which address multiple dimensions of SES may reduce transactional sex and ultimately prevent HIV transmission among AGYW.

Comparing Youth-Friendly Health Services to the Standard of Care Through "Girl Power-Malawi": A Quasi-Experimental Cohort Study.

BACKGROUND: Adolescent girls and young women (AGYW) face challenges to seeking HIV and sexual and reproductive health services in sub-Saharan Africa. Integrated approaches designed for AGYW may facilitate service uptake, but rigorous evaluation is needed. METHODS: Four comparable public-sector health centers were selected in Malawi and randomly assigned to a service delivery model. One offered "standard of care" (SOC), consisting of vertical HIV testing, family planning, and sexually transmitted infection management in adult-oriented spaces, by providers without extra training. Three offered youth-friendly health services (YFHS), consisting of the same SOC services in integrated youth-dedicated spaces and staffed by youth-friendly peers and providers. In each health center, AGYW aged 15-24 years were enrolled and followed over 12 months to determine use of HIV testing, condoms, and hormonal contraception. The SOC and YFHS models were compared using adjusted risk differences and incidence rate ratios. FINDINGS: In 2016, 1000 AGYW enrolled (N = 250/health center). Median age was 19 years (interquartile range = 17-21 years). Compared with AGYW in the SOC, those in the YFHS models were 23% [confidence interval (CI): 16% to 29%)] more likely to receive HIV testing, 57% (CI: 51% to 63%) more likely to receive condoms, and 39% (CI: 34% to 45%) more likely to receive hormonal contraception. Compared with AGYW in the SOC, AGYW in the YFHS models accessed HIV testing 2.4 (CI: 1.9 to 2.9) times more, condoms 7.9 (CI: 6.0 to 10.5) times more, and hormonal contraception 6.0 (CI: 4.2 to 8.7) times more. CONCLUSIONS: A YFHS model led to higher health service use. Implementation science is needed to guide scale-up.
