Rates and Determinants of Retention on ART Among Orphans and Vulnerable Children Living With HIV in Tanzania

Despite the global progress in response to HIV and AIDS, notable challenges remain for children, especially identification, linkage, and retention in HIV care and treatment services. To succeed in pediatric HIV programming requires the linkage and retention of the children in those services over time. This study assessed the level of retention to antiretroviral therapy (ART) and its associated factors among orphans and vulnerable children living with HIV (OVCLHIV) in Tanzania. Data were obtained from the USAID Kizazi Kipya project that collected pediatric ART data from October 2017 to October 2019 in 81 district councils of Tanzania. Community-based volunteers supported the linkage and retention of the OVCLHIV on ART. Analysis of on-ART status was conducted in a cohort of OVCLHIV aged 0–20 years enrolled in the project and monitored for 24 months. OVCLHIV who remained on ART until the end of the follow-up period were referred to as “retained,” otherwise, “not retained”. Multivariable analysis was conducted using logistic regression, adjusting for baseline characteristics. Of the 5,304 OVCLHIV analyzed, the mean age was 13.1 years, 51.5% were female, and 72.2% were living with female caregivers. Their overall rate of retention on ART over the 24 months was 86.7%. Multivariable analysis showed that as the higher frequency of home visit by the project staff increased, the likelihood of retention increased by 8% [adjusted odds ratio (aOR) = 1.08, 95% CI 1.06–1.11, p < 0.001]. Membership in people living with HIV (PLHIV) support groups was associated with a higher likelihood of retention compared to nonmembership (aOR = 3.31, 95% CI 2.60–4.21, p < 0.001). Children in larger family size were 22% less likely to sustain ART (aOR = 0.78, 95% CI 0.72–0.84, p < 0.001). Urban OVCLHIV were 18% less likely to remain on ART than their rural counterparts (aOR = 0.82, 95% CI 0.69–0.98, p = 0.030). Remaining on ART was 49% more likely for OVC in economically better-off households than those in destitute households (aOR = 1.49, 95% CI 1.22–1.81, p < 0.001). Male OVC were 17% less likely to be retained on ART than their female counterparts (aOR = 0.83, 95% CI 0.71–0.99, p = 0.033). Community-based OVC support resulted in a high pediatric retention rate over the 24 months of follow-up. While key enablers of retention were higher frequency of home visits by the project volunteer, participation in PLHIV support groups, and better economic status, large family sizes, urban place of residence, and male gender of the OVC were barriers. This study brings useful evidence to inform strategies for advancing retention of OVCLHIV on ART for their better health outcomes and overall wellbeing

Factors Associated with HIV Status Disclosure to Orphans and Vulnerable Children Living with HIV: Results from a Longitudinal Study in Tanzania

Background. The Tanzanian national guideline for pediatric HIV disclosure recommends beginning disclosure as early as age 4–6 years; full disclosure is recommended at the age of 8–10 years. Despite clear procedures, the disclosure rate in Tanzania remains relatively low. This study assessed the factors associated with HIV status disclosure to orphans and vulnerable children living with HIV (OVCLHIV). Methods. Data for this analysis come from the USAID-funded Kizazi Kipya program in Tanzania that provides health and social services to OVC and caregivers of HIV-affected households. Data were collected between January 2018 and March 2019. Disclosure status was self-reported by caregivers of children aged 8 years or above. Beneficiary characteristics were included as independent variables. Generalized estimating equations took into account the clustering effect of the study design. Results. Of the 10673 OVCLHIV, most were females (52.43%), and 80.67% were enrolled in school. More than half (54.89%) were from households in rural areas. Caregivers were mostly females (70.66%), three quarters were between 31 and 60 years old and had a complete primary education (67.15%), and 57.75% were HIV-infected. Most of the OVCLHIV (87.31%) had a disclosed HIV status. Greater OVCLHIV age p<0.001, school enrollment (OR = 1.22; 95% CI 1.06, 1.41), urban location of household (OR = 1.64; 95% CI 1.44, 1.86), caregivers’ higher education level p<0.001, and caregiver HIV-positive status (OR = 1.25; 95% CI 1.09, 1.43) were positively associated with disclosure status. OVCLHIV of female caregivers were 27% less likely to have been disclosed than those of male caregivers. Conclusion. The disclosure rate among OVCLHIV in this study was high. Disclosure of HIV status is crucial and beneficial for OVCLHIV continuum of care. Caregivers should be supported for the disclosure process through community-based programs and involvement of health volunteers. Policymakers should take into consideration the characteristics of children, their caregivers, and location of households in making disclosure guidelines as adaptable as possible
