Although nonadherence to prescribed therapies is widespread, it is particularly problematic with highly active antiretroviral therapy for HIV infection. This review of >50 studies in the area of pediatric HIV infection revealed varying methods for assessing antiretroviral adherence with a wide range of estimates of adherence. Correlates of adherence could be grouped as those relating to the medication, the patient, and the caregiver/family, with many conflicting findings and a lack of theory guiding the research. Only 8 studies, mainly small feasibility or pilot investigations, evaluated highly active antiretroviral therapy adherence interventions in pediatric populations. We conclude with specific recommendations for assessment and clinical management of adherence and discuss directions for future research in this area.

[4][5][6] The effects of nonadherence range from individual disability (eg, unrelieved pain) to global threat (eg, development of treatment-resistant bacteria or viruses). The yearly monetary costs of nonadherence exceed $100 billion. 7Adherence is particularly critical with highly active antiretroviral therapy (HAART) in the treatment of pediatric HIV infection. The data on HAART for pediatric HIV infection, although scarcer than for adults, suggest that medication adherence is a strong predictor of therapeutic impact. 8,9 For example, Wiener et al 10 observed that among children with an HIV-1 RNA viral load (VL) < 10 000, 75% had taken 100% of their medication doses in the previous week, whereas among those with a VL of ≥10 000, only 36% reported taking all of their medication.Despite the benefits of HAART in treating pediatric HIV infection [11][12][13][14][15] and the adverse consequences of nonadherence, adherence is reportedly suboptimal among children. [16][17][18][19][20] It is likely thwarted by multiple barriers 21,22 and complicated because, unlike with many other chronic illnesses, most children who are born with HIV in the United States are ethnic/racial minorities who live in chronic poverty with limited resources and face discrimination, family disruption, substance abuse, and the stressors of life in the inner city. 23 In addition, stigma is greater for HIV/AIDS than other chronic illnesses, which often leads caregivers to conceal the child's diagnosis a...
