Predictors of medication adherence in high risk youth of color living with HIV

The role of multiple identities in adherence to medical appointments among gay/bisexual male adolescents living with HIV

Adolescents living with HIV require engagement with care providers in order to access the critical medical and psychosocial services they need. The current study sought to explore developmental determinants of adherence to medical appointments as one aspect of engagement in care among a geographically diverse sample of 200 gay/bisexual male adolescents (16-24 years) living with HIV, with a specific focus on ethnic identity, sexual orientation identity, and identity as a young man living with HIV. Ethnic identity affirmation (OR = 0.6; 95% CI: 0.3, 0.9), morality of homosexuality (OR = 1.7; 95% CI: 1.2, 2.5), and HIV-positive identity salience (OR = 1.5; 95% CI: 0.9, 2.4) were associated with significantly higher risk for missed appointments in the past 3 months. These findings highlight the importance of attending to developmental factors, such as the development of multiple identities, when attempting to increase engagement in care for gay/bisexual male adolescents living with HIV.

Hepatitis A/B vaccine completion among homeless adults with history of incarceration

Hepatitis B virus (HBV) vaccination rates for incarcerated adults remain low despite their high risk for infection. This study determined predictors of vaccine completion in homeless adults (N= 297) who reported histories of incarceration and who participated in one of three nurse-led hepatitis programs of different intensity. Moreover time since release from incarceration was also considered. Just over half of the former prisoners completed the vaccine series. Older age (≥40), having a partner, and chronic homelessness were associated with vaccine completion. Recent research has documented the difficulty in providing vaccine services to younger homeless persons and homeless males at risk for HBV. Additional strategies are needed to achieve HBV vaccination completion rates greater than 50% for formerly incarcerated homeless men.

A biopsychosocial approach to asthma in adolescents encountering child protective services

OBJECTIVE

To further test the validity of the Biobehavioral Family Model (BBFM), a biopsychosocial approach to explaining the effects of family processes on illness, by testing the model with adolescents with asthma involved in child protective services (CPS), a sample for whom the model's constructs are highly relevant.

METHODS

Data are from the National Survey of Child and Adolescent Well-Being, CPS sample (n = 5,501). Adolescents with asthma (n = 101, ages 11-15 years) self-reported their negative family emotional climate (NFEC; caregiver psychological aggression and caregiver relationship quality), caregiver-adolescent relational security, and depressive symptoms. Caregivers rated adolescent health quality. Models were tested using path analyses and bootstrapping.

RESULTS

Path analyses and bootstrapping results demonstrate support for the BBFM in explaining health quality for this sample.

CONCLUSIONS

Applying the BBFM to families involved with CPS demonstrates pathways by which family processes affect health quality of adolescents with asthma, underscoring the need for biopsychosocial assessments and services.

Behavioral health risks in perinatally HIV-exposed youth: co-occurrence of sexual and drug use behavior, mental health problems, and nonadherence to antiretroviral treatment

In a sample of perinatally HIV-infected (PHIV+) and perinatally HIV-exposed, uninfected (PHEU) adolescents, we examined the co-occurrence of behavioral health risks including mental health problems, onset of sexual and drug use behaviors, and (in PHIV+ youth) nonadherence to antiretroviral therapy (ART). Participants, recruited from 2007 to 2010, included 349 youth, ages 10-16 years, enrolled in a cohort study examining the impact of HIV infection and ART. Measures of the above behavioral health risks were administered to participants and primary caregivers. Nearly half the participants met study criteria for at least one behavioral health risk, most frequently, mental health problems (28%), with the onset of sexual activity and substance use each reported by an average of 16%. Among the sexually active, 65% of PHIV+ and 50% of PHEU youth reported unprotected sex. For PHIV +youth, 34% reported recent ART nonadherence, of whom 45% had detectable HIV RNA levels. Between 16% (PHIV+) and 11% (PHEU) of youth reported at least two behavioral health risks. Older age, but not HIV status, was associated with having two or more behavioral health risks versus none. Among PHIV+ youth, living with a birth mother (versus other caregivers) and detectable viral load were associated with co-occurrence of behavioral health risks. In conclusion, this study suggests that for both PHIV+ and PHEU youth, there are multiple behavioral health risks, particularly mental health problems, which should be targeted by service systems that can integrate prevention and treatment efforts.

Strategies to improve HIV treatment adherence in developed countries: clinical management at the individual level

REMARKABLE ADVANCES IN THE TREATMENT OF HUMAN IMMUNODEFICIENCY VIRUS (HIV) DISEASE HAVE BEEN BLUNTED BY WIDESPREAD SUBOPTIMAL ADHERENCE (IE, NONADHERENCE), WHICH HAS EMERGED AS A MAJOR BARRIER TO ACHIEVING THE PRIMARY GOAL OF ANTIRETROVIRAL (ARV) THERAPY: suppression of HIV viral load. Nonsuppressed HIV viral load is associated with drug resistance, increased morbidity and mortality, and a higher risk of person-to-person HIV transmission. For HIV-infected individuals who are failing HIV treatment due to nonadherence, becoming adherent is a life-saving behavior change. However, overcoming nonadherence is one of the most daunting challenges in the successful management of HIV disease. The purpose of this paper is to provide clinicians with a better understanding of nonadherence to ARV treatment and to review the various factors that have been associated with either adherence or nonadherence. Strategies are presented that may help the nonadherent individual become ready to take HIV medications as prescribed.

Situational temptation for HIV medication adherence in high-risk youth

Abstract This study explored the role of situational temptation, a component of self-efficacy, in adolescent and young adult (ages 16-24) HIV medication adherence by assessing participants' perceptions of their temptation to miss medications in various situations (e.g., when medication causes physical side effects, when there is fear of disclosure of HIV status). Youth (n = 186; 83% African American) were participants in a multisite clinical trial examining the efficacy of a motivational intervention. Data were collected using computer-assisted personal interviewing. Youth believed the most tempting reasons or situations that might lead them to miss their HIV medications to be symptoms (if the medicine caused you to have other physical symptoms) and sick (if the medicine made you sick to your stomach or made you throw up or if it tasted bad), but these were not significantly associated with nonadherence. This suggests disconnection between youths' expectations of temptation and actual tempting situations associated with nonadherence. Situational temptations associated with nonadherence included lack of social support, needing a break from medications, and not seeing a need for medications. Interventions to improve adherence should consider perceptions of HIV medications, particularly the benefits of taking medications and expectations of physical symptoms. Interventionists and clinicians should consider situations that may tempt youth to miss doses of medication and help youth gain insight into these temptations. Emerging methods, such as Ecological Momentary Assessment (e.g., daily diaries, cell phone text messaging), may be useful in gaining insight into the day-to-day experience of youth living with HIV.

Improving health outcomes for youth living with the human immunodeficiency virus: a multisite randomized trial of a motivational intervention targeting multiple risk behaviors

OBJECTIVE

To determine if Healthy Choices, a motivational interviewing intervention targeting multiple risk behaviors, improved human immunodeficiency virus (HIV) viral load.

DESIGN

A randomized, 2-group repeated measures design with analysis of data from baseline and 6- and 9-month follow-up collected from 2005 to 2007.

SETTING

Five US adolescent medicine HIV clinics.

PARTICIPANTS

A convenience sample with at least 1 of 3 risk behaviors (nonadherence to HIV medications, substance abuse, and unprotected sex) was enrolled. The sample was aged 16 to 24 years and primarily African American. Of the 205 enrolled, 19 did not complete baseline data collections, for a final sample size of 186. Young people living with HIV were randomized to the intervention plus specialty care (n = 94) or specialty care alone (n = 92). The 3- and 6-month follow-up rates, respectively, were 86% and 82% for the intervention group and 81% and 73% for controls. Intervention Healthy Choices was a 4-session individual clinic-based motivational interviewing intervention delivered during a 10-week period. Motivational interviewing is a method of communication designed to elicit and reinforce intrinsic motivation for change. Outcome Measure Plasma viral load.

RESULTS

Youth randomized to Healthy Choices showed a significant decline in viral load at 6 months postintervention compared with youth in the control condition (beta = -0.36, t = -2.15, P = .03), with those prescribed antiretroviral medications showing the lowest viral loads. Differences were no longer significant at 9 months.

CONCLUSION

A motivational interviewing intervention targeting multiple risk behaviors resulted in short-term improvements in viral load for youth living with HIV. Trial Registration clinicaltrials.gov Identifier: NCT00103532.
