Adherence to antiretroviral therapy for pediatric HIV infection: review of the literature and recommendations for research.

This review described and compared empirical investigations of adherence to pediatric antiretroviral therapy (ART) and predictors/correlates of adherence with regard to methodology and outcome. Thirteen empirical studies of children's adherence to ART, conducted between the years 1981 and 2002 were identified. Investigations varied by age of participant, drug therapy regimen, method of adherence assessment, and by the reporting of predictors/correlates of adherence. Conclusions from the literature are limited by the lack of common sample characteristics and adherence assessment methodologies. Nevertheless, consistent with much of the pediatric adherence literature, adherence to antiretroviral medications among children and adolescents appears to be frequently suboptimal. Few investigations identified predictors/correlates of adherence, but these appear generally similar to those found in adult samples. Recommendations for future investigations are proposed.
