摘要:INTRODUCTION In recent years, global initiatives to address the AIDS epidemic have produced promising advances through access to effective treatment programs. However, lack of adherence to antiretroviral therapy is a problem for pediatric patients. OBJECTIVES Explore antiretroviral therapy adherence in children and adolescents living with HIV/AIDS in Cuba and examine its relationship with psychosocial, individual and treatment factors. METHODS A qualitative study was carried out of 21 caregivers of children and adolescents with HIV/AIDS. Demographics and information on treatment regimen were collected by chart review. Indepth interviews were conducted to assess adherence and examine its relationship with psychosocial, individual and treatment factors. Interviews were transcribed and the information was grouped by factor category. Adherence was analyzed in relation to these three sets of factors. RESULTS Caregivers interviewed reported adequate adherence in 17 of the 21 children. Lack of adherence was linked primarily to psychosocial factors such as additional responsibility taken on by the caregiver while grappling with his or her own illness, the presence of untreated psychological symptoms in the caregiver, perceived difficulties with family support, the child’s age, and assigning treatment responsibilities to the child without taking into account his/her psychological maturity. CONCLUSIONS The study revealed a high level of antiretroviral therapy adherence. It reconfirmed the fundamental importance of the caregiver and family support for therapeutic success in children and adolescents living with HIV/AIDS. These results, as well as the factors identified in cases of nonadherence, can contribute to a framework for assessment and specialized interventions to optimize pediatric antiretroviral adherence.
