Effect and cost-effectiveness of human-centred design-based approaches to increase adolescent uptake of modern contraceptives in Nigeria, Ethiopia and Tanzania: Population-based, quasi-experimental studies

Around half of adolescent pregnancies in low- and middle-income countries are unintended, contributing to millions of unsafe abortions per year. Adolescents 360 (A360), a girl-centred initiative, aimed to increase voluntary uptake of modern contraceptives among adolescents in Nigeria, Ethiopia and Tanzania. We evaluated the effectiveness and cost-effectiveness of A360 in increasing modern contraceptive use in selected geographies. We used before-and-after cross-sectional studies of adolescent girls in four settings. Two Nigerian settings had purposefully selected comparison areas. Baseline and endline household surveys were conducted. The primary study outcome was modern contraceptive prevalence rate (mCPR). Secondary outcomes mapped onto the A360 Theory of Change. Interpretation was aided by a process evaluation along with secular mCPR trends and self-reported A360 exposure data. Incremental design and implementation costs were calculated from implementer systems, site visits, surveys, and interviews. mCPR change was modelled into maternal disability-adjusted life years (DALY) averted to calculate incremental cost-effectiveness ratios. In Oromia, Ethiopia, mCPR increased by 5% points (95% CI 1-10; n = 1,697). In Nigeria, there was no evidence of an effect of A360 on mCPR in Nasarawa (risk ratio: 0·96, 95% CI: 0·76-1·21; n = 5,414) or in Ogun (risk ratio: 1·08, 95% CI: 0·92-1·26; n = 3,230). In Mwanza, Tanzania, mCPR decreased by 9% points (-17 to -0.3; n = 1,973). Incremental cost per DALY averted were $30,855 in Oromia, $111,416 in Nasarawa, $30,114 in Ogun, and $25,579 in Mwanza. Costs per DALY averted were 14-53 times gross domestic product per capita. A360 did not lead to increased adolescent use of modern contraceptives at a population level, except in Oromia, and was not cost-effective. This novel adolescent-centred design approach showed some promise in addressing the reproductive health needs of adolescents, but must be accompanied by efforts to address the contextual drivers of low modern contraceptive use.

The financial lives of female sex workers in Addis Ababa, Ethiopia: Implications for economic strengthening interventions for HIV prevention

Understanding the financial context of the lives of female sex workers (FSWs) is essential to address structural drivers of HIV risk. We used a financial diary methodology to record daily financial transactions over six weeks from a stratified purposive sample (n = 34) of FSWs in Addis Ababa, Ethiopia. FSWs also provided information on their experience with gender-based violence and condom use. FSWs generated 90.1% of total cash from sex work, with a median weekly income of USD 60.53. They engaged mostly in protected vaginal sex, earning approximately USD 4.57 per act. Food, housing, and clothing represented the largest areas of expenditure. Around 17% of expenses were recorded as costs of sex work (e.g., alcohol). Median weekly expenditures accounted for 62% of median weekly income. Nearly all participants reported depositing money into savings at least once over six weeks, while 71% reported a loan transaction during the six-week period, most as borrowers. Findings suggest that financial literacy and formalized savings activities, with life skills and empowerment training, have potential to build FSW's economic resilience, mitigating a structural driver of sex work and HIV risk.

Exploring the Use and Appeal of Playpens to Protect Infants from Exposure to Animals, Animal Feces, and Dirt in Rural Ethiopia

The persistence and pervasiveness of growth stunting in low- and middle-income countries spur reexamination of disease transmission pathways related to water, sanitation, and hygiene. Animal feces constitute a more important reservoir of enteric pathogens in homes in low-income countries than previously recognized, and exploratory object mouthing and direct ingestion of soil and animal feces represent underexplored exposure pathways. The effectiveness, adoption, constraints, and scale-up potential of measures for reducing infant and young children's exposure to fecal pathogens are recently beginning to be systematically explored. This mixed methods study tested the feasibility and appeal of using playpens to establish a hygienic "safe zone" for infants in rural Ethiopia. We conducted home trials of three playpen designs, including two models made from locally available materials through user-centered design. After using playpens for several weeks, caregivers reported extensive benefits, ranging from perceived safety to developmental and hygiene benefits for infants and relief from physical stress and worry for caregivers. We observed many playpens contaminated with Escherichia coli after weeks of use, though at concentrations below those of the common room floor on which infants might otherwise have played. Caregivers reported daily playpen use, but for intervals likely insufficient to protect infants from pathogen exposure affecting growth. We determine that playpens alone cannot plausibly protect infants from environmental contamination, but our results support further exploration of the potential benefits and commercial viability of scaling up use of playpens in rural, agricultural households as part of a comprehensive approach to child development and women's empowerment.

Factors Associated With Delayed Contraceptive Implant Removal in Ethiopia

Women receiving implant insertion at the community level were significantly more likely to report keeping their implant for more than 3 years. Even when a referral or back-up system for removals existed, efforts to task-shift the provision of contraceptive implants may have inadvertently led to extended implant use.

Background:

In 2009, the Government of Ethiopia initiated the implant scale-up initiative, which expanded contraceptive access by training health extension workers (HEWs) to insert single-rod etonogestrel contraceptive implants (Implanon) at rural health posts. Removals were provided by referrals to higher levels of the health system. However, little was known about whether women were getting their implants removed at the recommended 3-year postinsertion date or what barriers they faced to removal.

Methods:

Between June and July 2016, 1,860 Ethiopian women, who had a 1-rod etonogestrel implant inserted by either an HEW or another health care provider between 3 and 6 years prior, were surveyed. We describe the characteristics of the sample and use multivariable logistic regression to predict factors associated with keeping implants inserted beyond 3 years.

Results:

Women who had received their implants from HEWs were significantly more likely to report keeping them inserted for more than 3 years (adjusted odds ratio=2.50; 95% confidence interval=1.19, 5.24), compared with those who got their implant from another health care provider. Women who reported distance to the facility or transportation as a barrier were also significantly more likely to keep their implant for more than 3 years. Married and educated women were less likely to keep their implants for an extended duration. Among women who had their implant for 3 years or less, women who had had it inserted by an HEW were significantly more likely to report that the provider was unable or refused to provide removal as a barrier.

Discussion:

Efforts to expand lower level and community-based access to contraceptive implants that do not ensure reliable access to removals at the same level as insertions may lead to women using implants beyond the recommended duration.
