Determinants of nonsuppression of HIV viral load among children receiving antiretroviral therapy in the Simiyu region: a cross-sectional study.

BACKGROUND: Despite substantial antiretroviral therapy (ART) coverage among individuals with human immunodeficiency virus (HIV) infection in Tanzania, viral load suppression (VLS) among HIV-positive children receiving ART remains intolerably low. This study was conducted to determine factors affecting the nonsuppression of VL in children with HIV receiving ART in the Simiyu region; thus, an effective, sustainable intervention to address VL nonsuppression can be developed in the future. METHODS: We conducted a cross-sectional study including children with HIV aged 2-14 years who were currently presenting to care and treatment clinics in the Simiyu region. We collected data from the children/caregivers and care and treatment center databases. We used Stata™ to perform data analysis. We used statistics, including means, standard deviations, medians, interquartile ranges (IQRs), frequencies, and percentages, to describe the data. We performed forward stepwise logistic regression, where the significance level for removal was 0.10 and that for entry was 0.05. The median age of the patients at ART initiation was 2.0 years (IQR, 1.0-5.0 years), and the mean age at HIV VL (HVL) nonsuppression was 8.8 ± 2.99 years. Of the 253 patients, 56% were female, and the mean ART duration was 64 ± 33.07 months. In multivariable analysis, independent predictors of HVL nonsuppression were older age at ART initiation (adjusted odds ratio [AOR] = 1.21; 95% confidence interval [CI] 1.012-1.443) and poor medication adherence (AOR, 0.06; 95% CI 0.004-0.867). CONCLUSIONS: This study showed that older age at ART initiation and poor medication adherence play significant roles in HVL nonsuppression. HIV/AIDS programs should have intensive interventions targeting early identification, ART initiation, and adherence intensification.

Effectiveness of a community-based intervention (Konga model) to address factors contributing to low viral load suppression among children living with HIV in Tanzania: a preliminary, cluster, randomized clinical trial report.

BACKGROUND: Despite effective antiretroviral therapy (ART) coverage in other groups living with human immunodeficiency virus (HIV) in Tanzania, virologic suppression among HIV-positive children receiving ART remains unacceptably low. This study evaluated the effectiveness of a community-based intervention (Konga model) in addressing the factor contributing to low viral load suppression among children living with HIV in the Simiyu region, Tanzania. METHODS: This study used a parallel cluster randomized trial. The cluster was only eligible if the health facility provided HIV care and treatment. All eligible resident children aged 2‒14 years who attended the cluster with a viral load > 1,000 cells/mm were enrolled. The intervention included three distinct activities: adherence counseling, psychosocial support, and co-morbidity screening such as tuberculosis. The evaluation was based on patient-centered viral load outcomes measured at baseline and 6 months later. Using a pre- and post-test design, we compared the means of participants in the intervention and control groups. We performed an analysis of covariance. The effect of a Konga was calculated using omega-squared. We used F-tests, with their corresponding p-values, as measures of improvement. RESULTS: We randomly assigned 45 clusters to the treatment (15) and control (30) groups. We enrolled 82 children with amedian age of 8.8 years(interquartile range(IQR);5.5-11.2), and a baseline median viral load of 13,150 cells/mm (interquartile range (IQR);3600-59,200). After the study, both children in each group had good adherence, with children in the treatment group scoring slightly higher than those in the control group, 40 (97.56%) versus 31(75%61), respectively. At the end of the study, the difference in viral load suppression between the two groups was significant. The median viral load suppression at the end of the study was 50 cells/mm [IQR, (20-125)]. After adjusting for the viral load before the intervention, the effect size of the Konga intervention explained 4% (95% confidence interval [0%, 14.1%]) of the viral load variation at the end of the intervention. CONCLUSION: The Konga model demonstrated significant positive effects that improved viral load suppression. We recommend implementing the Konga model trial in other regions to improve the consistency of results.

Factors associated with low antiretroviral therapy enrollment of children in the Simiyu region: A cross-sectional Creswell mixed-methods sequential explanatory design.

Despite substantial antiretroviral therapy (ART) coverage in other groups with the human immunodeficiency virus (HIV) in Tanzania, there is a progressive decline in ART enrollment among HIV-infected children. This study aimed to determine the factors affecting the enrollment of children with HIV in ART and to identify an effective, sustainable intervention to address children's ART care enrollment. To achieve this, we conducted a cross-sectional study using a mixed-method sequential explanatory design, including children with HIV aged 2 to 14 years in the Simiyu region. Stata™ and NVIVO™ software were used to perform quantitative and qualitative data analyses, respectively. In the quantitative analyses, we considered 427 children, with a mean age of 8.54 ±â€…3.54 years and a median age of 3 years (interquartile range: 1-6 years). The mean length of ART initiation delay was 3.71 ±â€…3.21 years. Additionally, independent child enrollment predictors included distance to the facility (adjusted odds ratio [AOR]: 3.31; 95% confidence interval [CI]:1.14-9.58), caregivers' income (AOR: 0.17; 95% CI: 0.07-0.43), and fear of stigma (AOR: 3.43; 95% CI: 1.14-10.35). In qualitative analyses, 36 respondents reported that stigma, distance, and lack of HIV-positive status disclosure to their fathers were causes for low enrollment in ART. Overall, this study demonstrated that a caregiver's income, distance to obtain HIV care services, HIV-positive status non-disclosure to the father, and fear of stigma played a significant role in children's enrollment in HIV care. As such, HIV/acquired immunodeficiency syndrome programs would benefit from having intensive interventions to address distance, such as scaling up care and treatment centers, as well as techniques to reduce stigma in the population.

Dataset evaluating the effectiveness of the Konga model to address factors contributing to a low viral load suppression among children with HIV in Tanzania.

Data were collected for a cluster-randomized clinical trial of the Konga community-based intervention using a validated questionnaire for children and caregivers. The raw and analyzed data include 82 participants with the following information: sociodemographic characteristics (caregiver's age, sex, and level of education, income, and caregiver's marital status) and clinical characteristics of the children (weight, CD4 cell count, and viral load at baseline and after 6 months of follow-up. The other data included in this dataset were weight, medication adherence, and opportunistic infections. Analysis of covariance (ANCOVA) was performed using the baseline VL. The outcome was viral load at the end of the intervention. Additionally, Omega squared (ω2) was used to calculate the effect size as an estimation of the strength of the intervention. These data will help researchers analyze data from similar studies and evaluate the effectiveness of community-based interventions for viral load suppression.

Factors associated with adherence to oral HIV pre-exposure prophylaxis among female sex workers in the Mara Region, Tanzania: A 2022 cross-sectional study.

Female sex workers (FSWs) have a higher risk of acquiring human immunodeficiency virus (HIV) infection compared with the general female population. Tanzania adopted pre-exposure prophylaxis (PrEP) use for HIV-negative key populations in 2019 as a strategy to reduce HIV transmission. We aimed to identify factors associated with PrEP adherence among FSWs in Tanzania. We conducted a cross-sectional study of FSWs using oral HIV PrEP from June-July 2022 in 5 Mara Region districts. Stata software was used to analyze the quantitative data. Poor overall PrEP adherence was observed among FSWs, with adherence of 48.3% (174/360) and 43.3% (156/360) according to pill count and self-reports, respectively. Participants living with family members had 2.32 higher odds of PrEP adherence (adjusted odds ratio [aOR] = 2.32, 95% confidence interval [CI] = 1.27-42.23, P = .006) versus participants living alone or with friends. Moreover, FSWs who preferred pill packages had 1.41 higher odds of adherence (aOR = 2.43, [95% CI = 1.41-4.19, P = .001]); participants with a good perception of PrEP had 1.71 higher odds (aOR = 1.71, [95% CI = 1.01-2.91, P = .047]) of PrEP adherence. We found that living with family, pill packaging, and PrEP perception played significant roles in PrEP adherence among FSWs. Interventions to improve pill packaging, social support, and the perception of PrEP among FSWs should be intensified to increase adherence in this vulnerable population.
