Impact of armed conflicts on HIV treatment outcomes in sub-Saharan Africa: protocol for a systematic review and meta-analysis

Bridging the gap: Enhancing HIV care pathways for young key populations in Chad

Young key populations-sex workers and men who have sex with men (MSM)-face significant barriers to accessing HIV care in Chad due to stigma, discrimination, and socio-economic challenges. Although legal protections exist, gaps in enforcement continue to undermine care efforts. This study explored care pathways for young key populations in Chad to identify their specific challenges and propose targeted strategies to strengthen the HIV care continuum. Conducted in April 2025 in N'Djamena Chad, the qualitative study involved ten in-depth interviews with sex workers and MSM, aged 15-24 years, recruited through snowball sampling. Framework analysis revealed key themes across the HIV care continuum, specifically in testing, linkage to care, and retention in antiretroviral therapy (ART). Three major themes and 13 sub-themes emerged: (1) HIV testing and diagnosis, (2) linkage to care and ART initiation, and (3) retention in care and adherence to ART. Stigma-both externalized and internalized-was a significant barrier at every stage. Fear of disclosure, discrimination in healthcare settings, and financial constraints further hindered care engagement. Conversely, community-based awareness programs in faith-based institutions, and peer support networks were crucial in facilitating access to services. Addressing these challenges requires a comprehensive, multi-level approach that includes stigma-reduction training for healthcare workers, enforcement of anti-discrimination laws, targeted financial aid mechanisms, and integrated psychosocial counseling. Strengthening community-based interventions and peer-led outreach can further enhance engagement and retention, thereby improving health outcomes and reducing new infections among young key populations in Chad while aligning with global HIV targets.

The impact of armed conflicts on HIV treatment outcomes in Sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Despite the fact that Sub-Saharan Africa bears a disproportionate burden of armed conflicts and HIV infection, there has been inadequate synthesis of the impact of armed conflict on HIV treatment outcomes. We summarized the available evidence on the impact of armed conflicts on HIV treatment outcomes in Sub-Saharan Africa from 2002 to 2022.

METHODS

We searched four databases; MEDLINE, PubMed, CINHAL, and Scopus. We also explored grey literature sources and reviewed the bibliographies of all articles to identify any additional relevant studies. We included quantitative studies published in English from January 1, 2002 to December 30, 2022 that reported on HIV treatment outcomes for patients receiving antiretroviral therapy (ART) in conflict and post-conflict areas, IDP centers, or refugee camps, and reported on their treatment outcomes from sub-Saharan Africa. Studies published in languages other than English, reporting on non-ART patients and reporting on current or former military populations were excluded. We used EndNote X9 and Covidence to remove duplicates, extracted data using JBI-MAStARI, assessed risk of bias using AHRQ criteria, reported results using PRISMA checklist, and determined Statistical heterogeneity using Cochran Q test and Higgins I2, R- and RevMan-5 software were used for meta-analysis.

RESULTS

The review included 16 studies with participant numbers ranging from 102 to 2572. Lost To Follow-Up (LTFU) percentages varied between 5.4% and 43.5%, virologic non-suppression rates ranged from 25 to 33%, adherence rates were over 88%, and mortality rates were between 4.2% and 13%. A pooled meta-analysis of virologic non-suppression rates from active conflict settings revealed a non-suppression rate of 30% (0.30 (0.26-0.33), I2 = 0.00%, p = 0.000). In contrast, a pooled meta-analysis of predictors of loss to follow-up (LTFU) from post-conflict settings identified a higher odds ratio for females compared to males (1.51 (1.05, 2.17), I2 = 0%, p = 0.03).

CONCLUSION

The review highlights a lack of research on the relationship between armed conflicts and HIV care outcomes in SSA. The available documents lack quality of designs and data sources, and the depth and diversity of subjects covered.

Understanding the Effects of Trauma Exposure, Life Stress, Intimate Partner Violence, and Depression on Sexually Transmitted Infection Risk in Post-Conflict Liberia

In sub-Saharan Africa, sexually transmitted infections (STIs) are a public health concern. The impact of STIs are exacerbated in post-conflict low- and middle-income countries, such as Liberia, where exposure to traumatic events is prevalent and access to mental health services are limited. Following a syndemics framework, this study used regression analyses to explore the independent, additive, and multiplicative effects of four psychosocial conditions (exposure to war-related traumatic events, intimate partner violence [IPV], stressful life events, and depressive symptoms) on self-reported STIs. Data were collected from 379 youth aged 18-30 years (n = 170 women; n = 179 men) in Montserrado County, Liberia. Results revealed that psychosocial variables correlated with each other and STI risk. In multivariable analysis, stressful life events, depressive symptoms, and IPV were statistically significant predictors of STI risk. We found support for an additive effect between the number of psychosocial conditions reported and STI risk, as well as a multiplicative effect (interaction) between IPV and depressive symptoms on STI risk. Our results suggest a synergy between experiencing psychosocial conditions and STI risk and point to the potential benefit of multi-level sexual health approaches that simultaneously address mental health and IPV among youth in Liberia.
