Background: The World Health Organization recommends that children should be informed of their HIV status at age 6– 12 years. However, disclosure of HIV status among children is very low in resource-limited areas, particularly in Ethiopia. So, the aim of this study was to determine the prevalence of disclosure and associated factors among a cohort of HIV-infected children in southwest Ethiopia.
Methods: A facility-based cross-sectional study design was employed among caregivers of HIV-positive children aged 6– 15 in Bench sheko and West Omo zone Southwest Ethiopia, from March 1 to April 20, 2020. Study participants were included using a consecutive sampling technique. Data were collected using a pretested interviewer administered questionnaire and checklist. A multivariable logistic regressions model was used to identify independent predictors of disclosure. The significance of association was declared by AOR at 95% confidence and a p-value < 0.05.
Results: A total of 327 participants were involved in the study yielding a 95% response rate. The prevalence of HIV-positive status disclosure was 45.6% (95% CI=41.01– 51.02). Caregiver secondary education and above (AOR=3.16, 95% CI=1.07– 9.34), caregiver discussed about disclosure with health professionals (AOR= 9.56, 95% CI=4.88– 18.74), child age 10– 15 year old (AOR=3.64, 95% CI=1.64– 8.08), duration on ART > 5 years (AOR=5.08, 95% CI=1.57– 16.37), treatment follow-up at hospital (AOR=2.23, 95% CI=1.27– 5.01) and having treatment support for Children (AOR=3.84, 95% CI=1.88– 7.85) were independent predictors of HIV-positive status disclosure.
Conclusion: Disclosure of HIV status to children is low. Caregivers educational status, caregivers discussion with health professional, older child, duration on ART of more than 5 year, getting treatment service from hospital, and having a treatment support group are factors that enable disclosure. Therefore, concerted efforts based on the findings of this study will be required to improve the disclosure status among HIV-positive children.

Introduction

HIV has a devastating impact on both adults and children. Globally the number of people living with HIV was 38 million, of these 1.8 million were children (<15 years old) in 2019. Most (90%) of them were from sub-Saharan Africa.1 In Ethiopia, nearly 710,000 people were living with HIV; of these 59,000 were children less than 15 years old. However, only 38% of them were on antiretroviral therapy (ART).2

Disclosure has been defined as a state in which a child has knowledge about his/her HIV status.3 While there is convincing evidence on the benefits of developmentally appropriate pediatric HIV disclosure, the prevalence report is low because of different factors. It is challenging for healthcare providers, families, and caregivers as they face challenges on the decision when and how to disclose. Informing children of their HIV-positive status is important in the long-term management of HIV infection.4 However, the rate of disclosure to infected children varies widely throughout the world. In developed countries such as in the United States, a prospective study conducted among above 5 years old children shows that HIV diagnosis disclosure was reported up to 100%.5 In contrast, in resource-limited settings documented findings revealed very low levels of disclosure.6–8 Findings from low and middle income countries revealed that the level of HIV status disclosure ranges from 0–69%.5 In sub-Sahara Africa, 67.3% of caregivers did not disclose to the child about their HIV status.7

The World health organization (WHO) in 2011 released guidelines on HIV status disclosure for children should be from 6–12 years old.4 The African Network for the Care of Children Affected by HIV/AIDS (ANECCA) also recommends that pediatric HIV disclosure should start as early as 5–7 years old.9 Similarly, Ethiopian national HIV/AIDS treatment guidelines recommend the process of disclosure should begin as early as 4–6 years of age and it should be done over time.10 However, in Ethiopia, studies indicated that children who know their HIV-positive status range from 28.5–49.4%.11–14 Literature shows that disclosure of HIV status helps children to seek social support, free from the situation of accidental disclosure, and may decrease disruptive behaviors. Additionally, it would help to improve medication adherence, coping skills, and practice safer sex to prevent secondary transmission. The benefitis not limited to the child but also for caregivers by relieving the stress and anxiety that accompanies secrecy and deception, creating the opportunity to develop a trusting relationship and more open communication with the child.15–17

Studies conducted in Bale, North Gondar, and East Gojjam in Ethiopia show the prevalence of HIV disclosure to be 28.5%, 39.5%, and 33.3%, respectively. However, this study was not done in Bench sheko and West Omo zone Southwest Ethiopia. This area is a cash crop area and people are commonly engaged in traditional gold mining work. A study done in this area among gold mining workers shows that HIV preventive behavior of the mining workers was low.18 Therefore, this study intends to examine the magnitude and determinants of HIV disclosure status among children in Bench sheko and West Omo zone, Southwest Ethiopia. The study will help for evidence-based interventions and will fill the research gap in the study area as well for local evidence.

Methods and Materials

Study Area, Design, and Period

A facility-based cross-sectional study design was employed from March 1–April 20, 2020 in Bench sheko and West Omo zone, south west Ethiopia. The area is located 585 km from Addis Ababa, which is the center of Ethiopia. In Bench sheko and West Omo zone there are three public hospitals and 41 health centers. Among these facilities only three hospitals and 10 health centers are currently providing ART services. The total ART users in the study area were 4,148. Among those, 427 were children under 15 years old.

Population, Sample Size, and Sampling Methods

The study population included caregivers of HIV-positive children aged 6–15 years, on ART for at least 6 months and clinical monitoring charts of children. Sample size was determined taking the prevalence of HIV status disclosure among children from a study conducted in Bale,14 which was 28.5% and considering assumptions: alpha of 5% and 10% nonresponse rate. Then the final sample size became 344 caregivers of HIV-positive children aged 6–15 with their respective records. The calculated sample size was distributed proportionally to size for each health facility. Study participants were included using a consecutive sampling technique. Finally, all participants provided written informed consent prior to enrollment into the study.

Data Collection Tool, Procedures, and Quality Control

Structured questionnaires were developed after reviewing relevant literature. The questionnaire was prepared in English language, translated to the local language (Amharic and sheka) and then back to English to check its consistency. Two supervisors and six data collectors were recruited and offered 2 days of training on how to collect the data and clarification of the questionnaire before the actual task was undertaken. Then data were collected by interviewer administered questions using a structured questionnaire. Secondary data were extracted from records and a data base using a checklist which was prepared based on the patient monitoring chart.

Data Management and Analysis

Filled questionnaires were checked for completeness, cleaned, coded, and entered into EPI data statistical software version 3.1 and exported to SPSS windows version 23 for further analysis. Frequencies, proportions, and summary statistics were used to describe the study population in relation to relevant variables and presented using narration and tables. The Bivariate analysis was employed to identify candidate variables for multivariable analysis. Then variables found to have p-values of less than 0.25 were entered into the Multivariable Logistic regression for controlling the possible effects of confounders. Finally, variables which had significant associations were identified at a p-value <0.05 and Adjusted OR with 95% CI were determined to see the strength of the associations. Hosmer and Lemeshow test was used to check the fitness of the model.

Results

Sociodemographic Characteristics of Caregivers and HIV-Positive Children on ART

A total of 327 caregivers of HIV-positive children aged from 6–15 years participated in the study, yielding a 95% response rate. About three-fourths of the respondents were female and the mean age of the respondents was 36.39 years (SD=±6.798) (Table 1).

Table 1 Sociodemographic Characteristics of Caregivers of Bench Sheko and West Omo Zone, Southwest Ethiopia 2020 (n=327)

The mean age of the children was 10.39 (±2.394). The mean duration of stay on ART was 6.7 years (±2.413). More than half, 192 (58.7%) of the children on ART take medication with help from their caregivers. Seventy-eight (24%) of the HIV-positive children had lost his/her family because of HIV (Table 2).

Prevalence of HIV Status Disclosure to Infected Children

The prevalence of HIV disclosure to infected children was 45.6% (95% CI=41–1). The mean age among disclosed and non-disclosed infected children was 12.02 years (±1.769) and 9.03 years (±1.958), respectively. About 80 (53.7%) of HIV status disclosures were made by biological family, followed by 61 (40.9%) health professionals.

Factors Associated with HIV-Positive Status Disclosure to Infected Children

In bi-variable analysis 12 variables; age of caregivers, age of the child, residence, educational status of the caregivers, place of ART follow-up, presence of treatment support, history of admission, caregivers discussion with the health professionals about disclosure, caregivers knew other people who had a disclosure experience, age of the child at initiation of ART, duration on ART, and child questioning about their illness were found to be a candidate for the multivariable logistic regression model. Finally, six variables explained the final regression model. Educational status of the caregivers, caregivers discussion with health professionals about disclosure, age of the child, duration on ART, place of ART follow-up, and presence of treatment support for the child were independent predictors of HIV-positive status disclosure to infected children (Table 3).

Discussion

In this study the overall disclosure status of ART user’s children was 45.6% (95% CI=41–51). This finding was in line with studies done in Dire Dawa and Harari (49.4%), Gondar (44%), and West shoa (43.6%) in Ethiopia.12,13,19 This could be because of methodological similarities and possibly because the age groups studied were similar in Gondar and west shoa studies. But, this finding is lower than a study done in Uganda (56%) and Zimbabwe (66.9%).20,21 The possible justification might be a difference in study population selection. A study done in Uganda includes older adolescents, which overestimate the prevalence of disclosure. This might be due to older adolescents being able to get reach information through school or media and they are perceived matured to understand. On the other hand a study done in Zimbabwe used a prospective cohort design which allows a room to follow participants. Additionally there is a sociocultural difference. However, the prevalence of this study seems higher when compared to studies done in Nigeria (33%), Ghana (23.3%), Tanzania (33%), South Africa (27%), and also studies done in Ethiopia at Hawassa (33.3%) and Bale (28.5%).11,14,22–25 The possible reason could be due to sociocultural differences and methodological differences.

In this study, caregivers of HIV-positive children with secondary education were significantly more likely to have disclosed HIV status to their children compared to those with less education. This study is consistent with a study from Gondar Ethiopia.13 This could be that those educated caregivers may get reach information on the benefit of disclosure and may have a better understanding and problem-solving skills. However, this is in contrast with a study done in South Africa.26 Probably those educated might fear that children would inadvertently disclose their HIV status to others and thereby bring dishonor on the family despite their better understanding of the problem. On the other hand the sociocultural difference might confound the difference.

In this study, caregivers’ discussions with health professionals increase the chance of disclosure. Possible justification might be caregivers who had the opportunity to discuss disclosure with healthcare providers have more information and skills to inform the HIV status of their children. This was consistent with a study conducted in Tanzania.27

The age of the child was one independent predictor of disclosure. The odds of disclosure to HIV-positive children increase as the age of the child increases. Children in the age group between 10–15 years had an increased chance of disclosure. This could be explained that, as their age increases their maturity would increase and there was a higher opportunity for information. Therefore they would be expected to understand the condition. This study is supported by studies conducted in Bale, Gondar, Nigeria, South Africa, Tanzania, and Zimbabwe.13,14,21–23,25

In this study children on ART for more than 5 years had a significant association to disclosure. Those children who stayed on ART for a long period of time might have a possibility to ask questions about their illness and medication they use. In addition to this, repeated follow-up may create an opportunity for caregivers to disclose. This finding was in agreement with studies conducted in Hawassa and Bale, Ethiopia.11,14

ART follow-up at hospital was significantly associated to disclosure compared to health centers. This could be explained as commonly hospitals are found in a town, where there is high chance of access to information, whereas mainly health centers are found in remote areas to increase the accessibility of service. Additionally there might be a high turnover of staff from remote areas and a high chance of a cohort of skilled professionals in hospitals. This finding is in line with a study conducted in Gondar, northern Ethiopia.13

In this study having treatment support had an association with disclosure of HIV infection among children. This might be due to the reason that disclosure is a process which could take time. The presence of active treatment support would provide continuous guidance and facilitation to ease disclosure. This finding is in agreement with a previous study conducted in Bale, southeast Ethiopia.14

Disclosure of HIV status to infected children would have a great contribution to reduce HIV transmission in the population, improve drug adherence and enables psychosocial readiness and coping mechanism among HIV-positive children. Therefore, this would have a contribution for sustainable development goal 3 which aims to ensure healthy lives and promote well-being for all at all ages, including people living with HIV.  

A limitation of this study is that sociocultural factors have been missed. A further prospective study on a large size of study participants or randomized clinical trials is needed to better understand the actual predictors of disclosure among children living with HIV.

Conclusion

This study concludes that the prevalence of HIV-positive serostatus disclosure to infected children is low. The educational status of caregivers, caregivers discussion with health professionals, age of the child, duration on ART, place of ART follow-up and treatment support for the child were significantly associated with HIV-positive status disclosure among children on ART. Therefore, health professionals should strengthen disclosure counseling for caregivers as well as children and link children to treatment support groups. The zonal health office with health centers should strengthen the quality of ART service at health centers and they should take lessons from hospitals. Finally, the Ministry of Education should work on addressing education for all and should work more to end illiteracy in Ethiopia.
