Disclosing the diagnosis of human immunodeficiency virus (HIV) or AIDS to a child is a controversial and emotionally charged issue among both the health care communities and parents and caregivers of these children. This paper provides a systematic review of research on disclosure of pediatric HIV infection. It begins with a brief discussion of disclosure drawing from research on pediatric cancer. Next, we review the available research including patterns of disclosure, factors associated with disclosure and nondisclosure, and the effect of disclosure on psychological health and adherence. A review of published intervention studies is also included. While no consensus on when the diagnosis of HIV should be disclosed to a child or the psychological outcomes associated with disclosure was found, clinical consensus on several issues related to working with families was identified. We apply this literature to clinical practice and suggest avenues and directions for future research.

Objective: To examine sexual health disparities between blacks and whites in a national sample of US college students. Participants and Method Summary: Analyses utilized secondary data from 44,165 nonmarried undergraduates (aged 18–24; M = 20.1) responding to the Spring 2007 American College Health Association–National College Health Assessment; 64% were female and 94.7% were white. Results: Whites reported more experience in oral and anal sex, were less likely to use condoms for oral, anal, and vaginal sex, and less likely to have been tested for HIV (human immunodeficiency virus) compared with blacks. However, blacks reported more sex partners, lower use of hormonal contraceptives, and higher rates of adverse sexual health outcomes, such as sexually transmitted infections (STIs) and unintended pregnancy. Sexual behaviors and outcomes also varied across gender. Conclusions: This study highlights a need to increase access to hormonal contraceptives and early STI screening/treatment among blacks, improve HIV testing among whites, and increase condom use promotion for all students.

Recommendations suggest that older children and adolescents perinatally infected with HIV (PHIV+) be informed of their HIV diagnosis; however, delayed disclosure is commonly reported. This study examined the prevalence and timing of HIV disclosure to PHIV+ adolescents and the associations between the timing of disclosure and psychological functioning and other behavioral outcomes. Recruitment took place at four medical centers in New York City between December 2003 and December 2008. This sample included data from 196 PHIV+ youth and their caregivers: 50% of youth were male, 58% African American, 42% Hispanic, with a mean age of 12.71 years. According to caregiver reports, 70% of the PHIV+ youth knew their HIV diagnosis. Youths who had been told were more likely to be older; youths with a Spanish-speaking Latino caregiver and whose caregivers had a grade school education were told at an older age. Youths who had been told their HIV status were significantly less anxious than those who had not been told; there were no other differences in psychological functioning. Youths who knew their status for longer reported higher intentions to self-disclose to potential sex partners. In multivariate analyses only demographic differences associated with timing of disclosure remained. In summary, PHIV+ youth who had been told their HIV status did not show an increase of psychological problems and were more likely to have intentions to self-disclose to sexual partners. Yet, almost one third was entering puberty without important information regarding their illness. Caregivers need support to address factors impeding HIV disclosure.

This study examines the relationship between adherence to pediatric HIV regimens and three family experience factors: (1) regimen responsibility; (2) barriers to adherence; and (3) strategies for remembering to give medications. Caregivers of 127 children ages 2–15 years in the PACTS-HOPE multisite study were interviewed. Seventy-six percent of caregivers reported that their children were adherent (taking ≥ 90% of prescribed doses within the prior 6 months). Most caregivers reported taking primary responsibility for medication-related activities (72%–95% across activities); caregivers with primary responsibility for calling to obtain refills (95%) were more likely to have adherent children. More than half of caregivers reported experiencing one or more adherence barriers (59%). Caregivers who reported more barriers were also more likely to report having non-adherent children. Individual barriers associated with nonadherence included forgetting, changes in routine, being too busy, and child refusal. Most reported using one or more memory strategies (86%). Strategy use was not associated with adherence. Using more strategies was associated with a greater likelihood of reporting that forgetting was a barrier. For some families with adherence-related organizational or motivational difficulties, using numerous memory strategies may be insufficient for mastering adherence. More intensive interventions, such as home-based nurse-administered dosing, may be necessary.
