With the widespread use of highly active antiretroviral therapy, the epidemic of HIV has evolved into a chronic disease. HIV is extremely stigmatizing, resulting in highly emotionally charged responses to disclosure. World Health Organization (WHO) recommends that children should be informed of their HIV status at ages of 6 to 12 years and full disclosure at about 8 to 10 years. Disclosure process is much more difficult when the person being disclosed to is an adolescent. However, disclosure of HIV to a child should be an ongoing process that may last several years depending on the cognitive development of the child. This study investigated the determinants of HIV status disclosure among HIV infected adolescents. A total of 209 HIV infected adolescents (10-19 years) who have been on treatment for at least six months, and are taking lifelong anti-retroviral therapy from Bondo County Hospital, Got Agulu and Uyawi Sub County Hospital in Bondo Sub County were enrolled. Simple random sampling was employed in selecting the adolescents. Data was collected using a structured questionnaire. Quantitative data was analysed using both descriptive and inferential statistics while statistical tests including Pearson Correlation analysis and multiple linear regression were used to test the hypotheses. Findings on the overall parental perceptions regarding risks and benefits of disclosure and disclosure of HIV status to adolescents show that 180 (86.12%) of the respondents had a negative attitude compared to 29 (13.88%) who held a positive attitude. 122 (58.37%) of the respondents believed that overall availability and quality of counselling was moderate. 10 (4.78%) of the respondents believed that the overall availability and quality of counselling was high. Quality services and perception of the parents have been found to be good predictors of disclosure of HIV status among the newly diagnosed adolescents in Bondo sub-County, p-value<0.05.This study identified quality of service and perception of the parents as the two factors determining the disclosure of HIV status. There is a correlation between the parental perceptions regarding risks and benefits of disclosure and the quality of counselling to parental disclosure of HIV status to adolescents. Therefore the study recommends deliberate efforts to ensure quality service delivery and age specific disclosure counselling to caregivers to equip them with adequate knowledge on disclosure.
