Some authors argue that there are no predictors of adherence to medication, while others proffer indicators of likely adherence. These contextual factors are wide-ranging and may be interdependent. There are few studies of adherence in resource-poor settings. Of these, many were linked to particular trials whose conditions were highly controlled. For instance, the number of participants in the trial was small, the participants were strictly selected and they were offered much adherence support. These conditions will largely fall away with wider access to antiretroviral drugs (ARVs) such as South Africa is undertaking. Poor adherence remains one of the challenges to scaling-up access to ARVs, and, as such, the likely barriers to adherence need to be understood and countered. This study explores contextual factors - such as disclosure, preparation for treatment, treatment meaning and treatment acceptance - as aspects of lifestyle that can bear on adherence. Those who had disclosed were largely supported at household level, and after initial problems with adherence, participants adjusted and were able to include ARV treatment in their daily repertoire. Although the anticipation of stigma remains an obstacle to wide disclosure, antiretroviral therapy offers new hope and has the potential to impact on stigma.
Background: To explore adolescent HIV risk perception, HIV vaccine knowledge, willingness to participate in future HIV vaccine clinical trials, and the factors that influence willingness to participate among high school students in Soweto, South Africa, we recruited school-going youth through randomly selected local high schools. All pupils within the selected schools from whom parental consent and child assent could be obtained were eligible for participation. A selfadministered, facilitated questionnaire was completed by all participants.
Recent data indicate that the worldwide rate of HIV infection in adolescents is steadily increasing. Internationally, more than 7000 youths between 15 and 24 years of age are infected with HIV daily, resulting in more than 2.5 million new infections annually. Almost two thirds (1.7 million) of these new infections occur in Africa. Estimates in 2000 showed that the number of South Africans between 15 and 49 years of age infected with HIV was 4.7 million. This number equates to a prevalence rate of 15.4% in those younger than 20 years. Adolescents form an important target group not only for preventative efforts but also for HIV vaccine trials. This article focuses on the social and psychological factors that affect adolescent decision making by considering adolescent risk-taking behaviors, problems associated with predicting adolescent behavior, peer relationships and decision making, sexual disinhibition, and the role of family relationships in adolescent decision making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
