Background: The health benefits of antiretroviral treatment greatly depend on the extent to which people living with HIV/ AIDS adhere to the prescribed daily dosing regimens. Peer support groups are expected to have a high impact on adherence to medication among people living with HIV/AIDS. Objectives: This study was designed to determine factors affecting adherence to medication among people living with HIV/ AIDS in peer support and non-support groups attending antiretroviral clinics in Enugu State, Nigeria. Method: This was a cross-sectional, comparative study using qualitative and quantitative instruments among 840 people living with HIV/AIDS attending antiretroviral clinics in Enugu, Nigeria. Quantitative data was analysed using IBM SPSS version 22. A Chi-square test of statistical significance, a student t-test and multivariate analysis using binary logistic regression were used in the analysis. Manual content analysis was done for the qualitative data. Results: The mean age of respondents was comparable in both study groups: support group 38.5±9.6; and non-support group 38.5±10.1. A significantly higher proportion of respondents in the support group (91.9%) achieved good adherence compared with those in the non-support group (87.1%). A good medication adherence self-rating was a predictor of adherence in both study groups: support group (AOR 5.8, 95% CI: 2.7-12.2, p=<0.001) and non-support group (AOR 0.2, 95% CI: 0.1-0.4, p=<0.001). Conclusion: The peer-based intervention is a viable and effective tool for maintaining optimal adherence among people living with HIV/AIDS in resource-limited settings; hence, research should concentrate on interventions that do not focus on individuals alone, but rather on those that strengthen the capacity of groups to collectively participate in HIV programmes.

BackgroundHIV infection and AIDS are majorpublic health challenges in Nigeria, a country with one of the highest rates of new infection in sub-Saharan Africa and the second largest HIV epidemic in the world.Non-adherence to medication and defaulting from treatment are the two major challenges faced by anti-retroviral therapy (ART) programs in resource-constrained settings. This study was undertaken to determine the rate and predictors of adherence to medication and retention among people living with HIVin Enugu State, Nigeria.MethodsThis was a cross-sectionalretrospective study conducted among adults living with HIV(PLHIV) receiving ARTs in eightcomprehensive health facilities in Enugu, Nigeria. We used self-reported adherence and recorded clinic visits to assess adherence and retention, respectively. Descriptive statistics (frequencies, proportions, mean and standard deviation) and regression analysis were then conducted to identify the association between adherence, retention and demographic and health-related factors. ResultsThe mean age of respondents was 38.5±9.8 years. Predictors of good adherence to medication includedbeing male(adjusted odds ratio [AOR]:2.08; 95% confidence interval [CI]:1.12–3.85), having been on anti-retroviral medications for more than 5 years (AOR:1.92; 95% CI: 1.17–3.16), the non-consumption of alcohol(AOR: 3.67; 95% CI: 2.01–6.70),not usingtraditional medicine (AOR: 2.76; 95% CI:1.33–5.73) and having a baseline CD4count exceeding 500 cells/μl (AOR: 5.67; 95% CI: 1.32–24.32).Adequate retention was predicted by being resident in the urban area (AOR: 1.90; 95% CI: 1.17–3.06). Being away from home (41.8%) and forgetfulness (35.0%) were reported as the major reasons for missing medication.ConclusionThe rates of adherence and retention found in this study were similar to those reported forother resource-limited settings. Health education and behavioural modification interventions should be intensified to reduce the consumption of alcohol and the use of traditional medicine by people living with HIV. Identifying other factors may help to design effective strategies to ensure that people living with HIV adhere to their medications and remain in care.
