Objective: To update the prior systematic review from studies published in the past 9 years that examine the effects of condom social marketing (CSM) programs on condom use in low- and middle-income countries. Data Sources: PubMed, CINAHL, PsycINFO, Sociological Abstracts, and EMBASE. Hand searching of AIDS, AIDS and Behavior, AIDS Care, and AIDS Education and Prevention. Study Inclusion and Exclusion Criteria: (a) Published from 1990 to January 16, 2019, (b) low- or middle-income country, (c) evaluated CSM, (d) analyses across preintervention to postintervention exposure or across multiple study arms, (e) measured condom use behavior, and (f) sought to prevent HIV transmission. Data Extraction: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 2 reviewers extracted citation, inclusion criteria, methods, study population, setting, sampling, study design, unit of analysis, loss to follow-up, comparison group characteristics, intervention characteristics, and eligible outcome results. Data Synthesis: The 2012 review found 6 studies (combined N = 23 048). In a meta-analysis, the pooled odds ratio for condom use was 2.01 (95% confidence interval [CI]: 1.42-2.84) for the most recent sexual encounter and 2.10 (95% CI: 1.51-2.91) for a composite of all condom use outcomes. Studies had significant methodological limitations. Of 518 possible new citations identified in the update, no new articles met our inclusion criteria. Conclusions: More studies are needed with stronger methodological rigor to help provide evidence for the continued use of this approach globally. There is a dearth of studies over the past decade on the effectiveness of CSM in increasing condom use in low- and middle-income countries (LMIC).

Objectives: We assessed the effectiveness of 2 environmental-structural interventions in reducing risks of HIV and sexually transmitted infections (STIs) among female sex workers in the Dominican Republic. Methods: Two intervention models were implemented over a 1-year period: community solidarity in Santo Domingo and solidarity combined with government policy in Puerto Plata. Both were evaluated via preintervention-postintervention cross-sectional behavioral surveys, STI testing and participant observations, and serial cross-sectional STI screenings. Results: Significant increases in condom use with new clients (75.3%-93.8%; odds ratio [OR] = 4.21; 95% confidence interval [CI] = 1.55, 11.43) were documented in Santo Domingo. In Puerto Plata, significant increases in condom use with regular partners (13.0%-28.8%; OR = 2.97;95% CI = 1.33, 6.66) and reductions in STI prevalence (28.8%-16.3%; OR = 0.50; 95% CI = 0.32, 0.78) were documented, as were significant increases in sex workers' verbal rejections of unsafe sex (50.0%-79.4%; OR = 3.86; 95% CI = 1.96, 7.58) and participating sex establishments' ability to achieve the goal of no STIs in routine monthly screenings of sex workers (OR = 1.17; 95% CI = 1.12, 1.22). Conclusions: Interventions that combine community solidarity and government policy show positive initial effects on HIV and STI risk reduction among female sex workers.

A recent Horizons study conducted jointly with two Dominican NGOs assessed the impact of two environmental-structural models in reducing HIV-related risk among female sex workers in the Dominican Republic and compared their cost-effectiveness. In the two cities studied, there were improvements from pre- to post-intervention in the key outcome variables, however the type and level of these changes varied by intervention approach. Based on our findings, program planners and policymakers involved in the study in the Dominican Republic agree that the integrated solidarity and policy model in conjunction with ongoing peer education and community mobilization activities is an appropriate, cost-effective, and ethical intervention package. The current dialogue is now focused on how to scale up this successful pilot experience in a way that continues to respect all members of the sex work community and to be effective in curbing the HIV epidemic.

Effective programs that avert new HIV infections among sex workers and their partners, and hence the general population, are critical components of national HIV-prevention strategies. Prevention efforts have frequently relied on interventions that reach members of these vulnerable groups as individuals, such as condom promotion and STI management. Now, many researchers and program implementers are increasingly turning to "environmental-structural" interventions that address the physical, social, and political contexts in which individual behavior takes place. A recent Horizons study conducted jointly with two Dominican NGOs—Centro de Orientación e Investigación Integral and Centro de Promoción e Solidaridad Humana—and the National Program for the Control of STDs and AIDS assessed the impact of two environmental-structural models in reducing HIV-related risk among female sex workers in the Dominican Republic and compared their cost-effectiveness. As detailed in this brief, the models, built on years of experience gained from sex worker peer education programs, drew from the strengths of both community solidarity and government policy initiatives and engaged community members in both program and policy development.

Programas efectivos para evitar nuevas infecciones del VIH entre trabajadoras sexuales y sus parejas, y por lo tanto la población en general, son componentes críticos de estrategias nacionales de prevención del VIH. Generalmente los esfuerzos de prevención se han concentrado en intervenciones que alcanzan a los miembros de estos grupos vulnerables al nivel individual, tal como promoción de condones y manejo de ITS. Actualmente, muchos investigadores y gerentes de programas se encuentran dirigiéndose a intervenciones "ambientales-estructurales" que toman en cuenta los contextos físicos, sociales y políticos en que el comportamiento individual ocurre. Un estudio reciente realizado por Horizons, en conjunto con dos ONGs dominicanas—Centro de Orientación e Investigación Integral y Centro de Promoción y Solidaridad Humana—y el Programa Nacional del Control de ITS y SIDA buscaba evaluar el impacto de dos modelos ambientales-estructurales en disminuir el riesgo de VIH entre trabajadoras sexuales en la República Dominicana y de comparar el costo-efectividad de los dos modelos. Como se detalla en este resumen, los modelos, construidos sobre la base de años de experiencia adquirida a través de programas de educación entre pares de trabajadoras sexuales, combinan las fortalezas de iniciativas de solidaridad comunitaria y de políticas gubernamentales, e involucran a miembros de la comunidad en el desarrollo de ambos programa y política. --- Effective programs that avert new HIV infections among sex workers and their partners, and hence the general population, are critical components of national HIV-prevention strategies.
