RESUMO

In the present study, we examined the associations between physical characteristics of neighborhoods and sleep health outcomes and assessed the mediating role of physical activity in these associations. A longitudinal study (the Pittsburgh Hill/Homewood Research on Eating, Shopping, and Health (PHRESH) Zzz Study; n = 1,051) was conducted in 2 low-income, predominately African-American neighborhoods in Pittsburgh, Pennsylvania, with repeated measures of neighborhood characteristics and sleep health outcomes from 2013 to 2018. Built environment measures of walkability, urban design, and neighborhood disorder were captured from systematic field observations. Sleep health outcomes included insufficient sleep, sleep duration, wakefulness after sleep onset, and sleep efficiency measured from 7-day actigraphy data. G-computations based on structural nested mean models were used to examine the total effects of each built environment feature, and causal mediation analyses were used to evaluate direct and indirect effects operating through physical activity. Urban design features were associated with decreased wakefulness after sleep onset (risk difference (RD) = -1.26, 95% confidence interval (CI): -4.31, -0.33). Neighborhood disorder (RD = -0.46, 95% CI: -0.86, -0.07) and crime rate (RD = -0.54, 95% CI: -0.93, -0.08) were negatively associated with sleep efficiency. Neighborhood walkability was not associated with sleep outcomes. We did not find a strong and consistent mediating role of physical activity. Interventions to improve sleep should target modifiable factors, including urban design and neighborhood disorder.

RESUMO

Perinatal depression has been shown to impede adherence to antiretroviral therapy (ART) and the prevention of mother-to-child transmission (PMTCT) care continuum; therefore, treating perinatal depression may result in increased viral suppression and PMTCT adherence. We examined the effects of the M-DEPTH (Maternal Depression Treatment in HIV) depression care model (including antidepressants and individual Problem Solving Therapy) on depression, maternal viral suppression and adherence to PMTCT care processes in an ongoing cluster-randomized controlled trial of 391 HIV-infected pregnant women (200 usual care; 191 intervention) with at least mild depressive symptoms enrolled across 8 antenatal care clinics in Uganda. At baseline, 68.3% had clinical depression and 41.7% had detectable HIV viral load. Adjusted repeated-measures multivariable regression models found that the intervention group was nearly 80% less likely to be clinically depressed [Adjusted OR (95% CI) 0.22 (0.05, 0.89)] at the 2-month post-pregnancy assessment, compared to the control group. However, the intervention and control groups did not differ meaningfully on maternal viral suppression, ART adherence, and other PMTCT care processes and outcomes. In this sample of women who were mostly virally suppressed and ART adherent at baseline, the depression care model had a strong effect on depression alleviation, but no downstream effects on viral suppression or other PMTCT care processes.Trial Registration NIH Clinical Trial Registry NCT03892915 (clinicaltrials.gov).

RESUMO

BACKGROUND: Black Americans have disproportionately higher rates and earlier onset of Alzheimer's disease and related dementias (ADRD) relative to White Americans. We currently lack a comprehensive understanding of how the lived experience and broader societal factors, including cumulative exposure to structural racism and the mechanisms underlying the risks, may contribute to elevated ADRD risk in Black Americans. METHODS: The Think PHRESH study builds on existing, community-based research infrastructure, from the ongoing Pittsburgh Hill/Homewood Research on Neighborhood Change and Health (PHRESH) studies, to examine the contributions of dynamic neighborhood socioeconomic conditions across the lifecourse to cognitive outcomes in mid- and late-life adults living in two historically disinvested, predominantly Black communities (anticipated n = 1133). This longitudinal, mixed-methods study rests on the premise that neighborhood racial segregation and subsequent disinvestment contributes to poor cognitive outcomes via factors including (a) low access to educational opportunities and (b) high exposure to race- and socioeconomically-relevant stressors, such as discrimination, trauma, and adverse childhood events. In turn, these cumulative exposures foster psychological vigilance in residents, leading to cardiometabolic dysregulation and sleep disruption, which may mediate associations between neighborhood disadvantage and ADRD risk. This premise recognizes the importance of potential protective factors that may promote cognitive health, including neighborhood social cohesion, safety, and satisfaction. The proposed study will leverage our existing longitudinal data on risk/protective factors and biobehavioral mediators and will include: (1) up to three waves of cognitive assessments in participants ages 50 years + and one assessment in participants ages 35-49 years; clinical adjudication of ADRD will be completed in participants who are 50+, (2) extensive surveys of risk and protective factors, (3) two assessments of blood pressure and objectively measured sleep, (4) a comprehensive assessment of life and residential history; and (5) two rounds of in-depth qualitative interviews to reveal lifecourse opportunities and barriers experienced by Black Americans in achieving optimal cognitive health in late life. DISCUSSION: Understanding how structural racism has influenced the lived experience of Black Americans, including dynamic changes in neighborhood conditions over time, is critical to inform multi-level intervention and policy efforts to reduce pervasive racial and socioeconomic disparities in ADRD.

RESUMO

BACKGROUND: Black adults in the U.S. experience significant health disparities related to tobacco use and obesity. Conducting observational studies of the associations between smoking and other health behaviors and indicators among Black adults may contribute to the development of tailored interventions. PURPOSE: We examined associations between change in cigarette smoking and alcohol use, body mass index, eating behavior, perceived stress, and self-rated health in a cohort of Black adults who resided in low-income urban neighborhoods and participated in an ongoing longitudinal study. METHODS: Interviews were conducted in 2011, 2014, and 2018; participants (N = 904) provided at least two waves of data. We fit linear and logistic mixed-effects models to evaluate how changes in smoking status from the previous wave to the subsequent wave were related to each outcome at that subsequent wave. RESULTS: Compared to repeated smoking (smoking at previous and subsequent wave), repeated nonsmoking (nonsmoking at previous and subsequent wave) was associated with greater likelihood of recent dieting (OR = 1.59, 95% CI [1.13, 2.23], p = .007) and future intention (OR = 2.19, 95% CI [1.61, 2.98], p < .001) and self-efficacy (OR = 1.64, 95% CI [1.21, 2.23], p = .002) to eat low calorie foods, and greater odds of excellent or very good self-rated health (OR = 2.47, 95% CI [1.53, 3.99], p < .001). Transitioning from smoking to nonsmoking was associated with greater self-efficacy to eat low calorie foods (OR = 1.89, 95% CI [1.1, 3.26], p = .021), and lower perceived stress (ß = -0.69, 95% CI [-1.34, -0.05], p = .036). CONCLUSIONS: We found significant longitudinal associations between smoking behavior and eating behavior, perceived stress, and self-rated health. These findings have implications for the development of multiple behavior change programs and community-level interventions and policies.

RESUMO

We evaluated the effects of a culturally adapted evidence-based HIV prevention intervention (Mpowerment), named "Tayf", on condom use and HIV testing among young men who have sex with men (YMSM) in Beirut. A 2-year implementation of Tayf was carried out independently and in parallel with a research cohort of 226 YMSM who were surveyed at baseline and months 6, 12, 18 and 24 after Tayf initiation. Primary outcomes were (1) any condomless anal sex with HIV-positive or unknown status partners in the past 3 months, and (2) HIV testing in the past six months. Hierarchical logistic regression models examined the association of Tayf participation with the outcomes averaged across all assessments, and the moderating effect of Tayf participation on change in the outcomes over the follow-up period. A total of 331 YMSM attended at least one event, including 33% of the cohort. Tayf participation was associated with a higher rate of any condomless sex with HIV-positive or unknown status partners averaged across the five assessments, but there was no moderating effect of Tayf participation on change in this outcome over time. Tayf participation was associated with higher HIV testing when averaged across all assessments, but its interaction with time showed that the strength of this association diminished over time. In conclusion, Tayf proved feasible and acceptable in Beirut, but with limited effects. Further work is needed, including innovative publicity and marketing strategies, to bolster effects in high stigma settings where security and legal risks are prominent.

RESUMO

Supporting Treatment Adherence Readiness through Training (START) is an HIV antiretroviral adherence intervention, based on the Information Motivation and Behavioral skills (IMB) model, that significantly improved adherence in our randomized controlled trial. To understand how and for whom START had its effects on adherence, we examined mediators and moderators. Ninety-nine HIV-patients (53 control, 46 intervention) who enrolled in the trial and provided month 6 electronic monitored adherence data. The intervention was associated with increased adherence-related knowledge and lower impulsive/careless problem solving, but had no effects on other IMB-related constructs. Neither of these variables mediated the adherence effects of the intervention (based on linear regression models with bootstraping for unbiased standard errors). Four variables interacted with the intervention to moderate its effects: the intervention group had consistent high adherence across the range of depression and time since HIV diagnosis, compared to lower adherence with higher values in the usual care control; those with unstable housing or frequent drug use had higher adherence if in the intervention group compared to the control group. These findings suggest that START provides support that enables its recipients to cope with and overcome challenges (e.g., depression, unstable housing, drug use) that would typically impede adherence.Trial registration: ClinicalTrials.gov identifier: NCT02329782.

RESUMO

Neighborhood socioeconomic conditions (NSECs) are associated with resident diet, but most research has been cross-sectional. We capitalized on a natural experiment in Pittsburgh, Pennsylvania, in which 1 neighborhood experienced substantial investments and a sociodemographically similar neighborhood that did not, to examine pathways from neighborhood investments to changed NSECs and changed dietary behavior. We examined differences between renters and homeowners. Data were from a random sample of households (n = 831) in each of these low-income Pittsburgh neighborhoods that were surveyed in 2011 and 2014. Structural equation modeling tested direct and indirect pathways from neighborhood to resident dietary quality, adjusting for individual-level sociodemographics, with multigroup testing by homeowners versus renters. Neighborhood investments were directly associated with improved dietary quality for renters (ß = 0.27, 95% confidence interval (CI): 0.05, 0.50) and homeowners (ß = 0.51, 95% CI: 0.10, 0.92). Among renters, investments also were associated with dietary quality through a positive association with commercial prices (ß = 0.34, 95% CI: 0.15, 0.54) and a negative association with residential prices (ß = -0.30, 95% CI: -0.59, -0.004). Among homeowners, we did not observe any indirect pathways from investments to dietary quality through tested mediators. Investing in neighborhoods may support resident diet through improvements in neighborhood commercial environments for renters, but mechanisms appear to differ for homeowners.

RESUMO

The START (Supporting Treatment Adherence Readiness through Training) intervention was examined for its effects on ART adherence and virologic suppression relative to usual care. A sample of 176 clients about to start or restart ART were randomized (83 to START, 93 to usual care) at HIV clinics in the Los Angeles area. Primary outcomes included electronically monitored dose-taking adherence and HIV viral load; primary end points were months 6 and 24, with group differences examined using nonresponse-weighted means or proportions, effect sizes, and significance testing. Item nonresponse was addressed using multiple imputation. 166 (94.3%) participants started ART, of whom 124 (74.7%) were still in care at month 6, and 90 (54.2%) at month 24. In comparison to the usual care control group, the START group had higher dose-taking adherence at month 6 (86.2% vs. 71.6%, d = 0.56, p = 0.01), which was sustained through month 24 (86.0% vs. 61.1%, d =1.01, p < 0.0001). While rates of undetectable viral load did not differ between groups at month 6 or 24, the mean reduction in viral load (log10 copies/mm3) at month 24 was significantly greater in the intervention arm (3.0 vs. 2.7; d = 0.40, p = 0.047). An estimated cost of $132 per person was needed to obtain a 10% increase in dose-taking adherence over 24 months from the intervention. These findings suggest that START is cost effective in producing a medium to large effect on dose-taking adherence that is durable over 24 months, and a modest long-term effect on viral reduction.Trial registration Clinicaltrials.gov NCT02329782 (registered December 22, 2014).

RESUMO

The Middle East and North Africa (MENA) is one of only two global regions where rates of HIV are currently on the rise. In Lebanon, new HIV infections are increasing most rapidly among young men who have sex with men (YMSM). While, the majority of YMSM in Lebanon report having recently engaged in condomless anal intercourse, many report reluctance to seek HIV prevention services for fear of stigma and discrimination. Pre-exposure prophylaxis (PrEP) is an effective alternative HIV prevention strategy but there is a dearth of research looking at willingness to take PrEP among YMSM in MENA. This study is the first to delineate factors associated with willingness to take PrEP among a cohort of 218 YMSM recruited from Beirut, Lebanon. Over half (55.5%) reported willingness to take PrEP. At the bivariate level, knowledge of HIV risk, awareness of PrEP, being in a relationship, greater judgementalism about sex in communication with peers, greater number of types of gay-related discrimination experienced, sense of community among YMSM, having had recent condomless anal sex with positive or unknown status partner, and the use of substances just prior to or during sex were each associated with greater willingness to take PrEP. When entered into a linear regression analysis, use of substances just prior to or during sex and sense of community among YMSM remained significant predictors of PrEP willingness. Intervention efforts focused on increasing PrEP uptake among YMSM in MENA should consider the influence substance use and social factors on willingness to take PrEP.

RESUMO

Studies have documented how levels and change in depression correspond to ART non-adherence. However, few studies have examined how levels of and change in adherence may relate to levels of and change in depression, although one might expect mental health to be related to physical health and how successful one is in managing disease. To assess the bidirectional nature of the association between these two constructs, we examined data from a prospective trial of an ART adherence intervention in Uganda that followed 143 participants over 20 months. Adherence was measured using electronic monitoring caps; non-adherence was defined as missing > 10% of prescribed doses; self-reported depression was measured using the Patient Health Questionnaire (PHQ-9), and PHQ-9 > 4 defined the presence of at least minor depression. Adjusted linear and logistic regression models were used to examine the longitudinal relationships between depression and non-adherence. At baseline, 40.6% had at least minor depression and 37.1% were non-adherent. Time varying change in the classification of depression (e.g., becoming depressed) predicted change in non-adherence status (e.g., becoming non-adherent), and this association remained when examining continuous measures of the constructs. Similarly, time varying measures of increases in non-adherence predicted increases in depression, regardless of whether continuous or binary classification measures were used. A temporal trend of increased non-adherence over time was observed, and this was accelerated by an increase in depression. Furthermore, those who had at least minor depression at baseline were more likely to be non-adherent at follow-up. These findings support the potential benefits of depression care and adherence support for improving adherence and mental health, respectively, and call for further research to examine such benefits.The trial has been registered with ClinicalTrials.gov (NCT02503072).

RESUMO

African Americans and socioeconomically disadvantaged individuals have higher rates of a variety of sleep disturbances, including short sleep duration, poor sleep quality, and fragmented sleep. Such sleep disturbances may contribute to pervasive and widening racial and socioeconomic (SES) disparities in health. A growing body of literature demonstrates that over and above individual-level SES, indicators of neighborhood disadvantage are associated with poor sleep. However, there has been scant investigation of the association between sleep and the most proximal environments, the home and residential block. This is the first study to examine the association between objective and self-reported measures of housing and block conditions and sleep. The sample included 634 adults (mean age = 58.7 years; 95% African American) from two low-income urban neighborhoods. Study participants reported whether they experienced problems with any of seven different housing problems (e.g., broken windows) and rated the overall condition of their home. Trained data collectors rated residential block quality. Seven days of wrist actigraphy were used to measure average sleep duration, efficiency, and wakefulness after sleep onset (WASO), and a sleep diary assessed sleep quality. Multivariate regression analyses were conducted for each sleep outcome with housing or block conditions as predictors in separate models. Participants reporting "fair" or "poor" housing conditions had an adjusted average sleep duration that was 15.4 min shorter than that of participants reporting "good" or "excellent" conditions. Those reporting any home distress had 15.9 min shorter sleep and .19 units lower mean sleep quality as compared with participants who did not report home distress. Poor objectively measured block quality was associated with 14.0 min shorter sleep duration, 1.95% lower sleep efficiency, and 10.7 additional minutes of WASO. Adverse housing and proximal neighborhood conditions are independently associated with poor sleep health. Findings highlight the importance of considering strategies that target upstream determinants of sleep health disparities.

RESUMO

In 2012, our research with young men who have sex with men (YMSM) in Beirut showed high rates of recent condomless anal sex and low rates of recent HIV testing. In 2017, we collected data from YMSM to assess for temporal changes and sociodemographic correlates. Propensity score weighting was used to eliminate any sociodemographic differences between the 2012 (n = 164) and 2017 (n = 226) samples of YMSM (age 18-29) recruited with long-chain peer referral sampling. Regression analysis was used to examine sociodemographic correlates of recent condomless anal sex and HIV testing using the 2017 sample, and whether these behaviors differed between the samples. Compared to the 2012 sample, the 2017 sample was about half as likely to report any condomless anal sex in the past 3 months with partners whose HIV status was positive or unknown (14% vs. 23%; OR [95%CI] 0.56 [0.32, 0.98]), and nearly 2.5 times as likely to report HIV testing in the past 6 months (48% vs. 27%; OR [95%CI] 2.44 [1.46, 4.10]). In the 2017 sample, any recent condomless anal sex with partners whose HIV status was positive or unknown was associated with employment and Christian religious affiliation. Low income was the sole correlate of having recently tested for HIV. These findings suggest a temporal trend toward increased HIV protective behaviors among YMSM in Beirut over the past 5 years. Further inroads could be secured if HIV prevention programming targeted economic influences.

RESUMO

Objective/Background: Food Insecurity (FI) can be a profound source of stress, which may increase the risk for sleep disturbance. This is the first study to examine the association between FI and objectively and subjectively measured sleep. Participants: The sample included 785 adults living in two low-income neighborhoods (mean age = 56; 95% African American). Methods: FI was measured using a validated 10-item survey that assesses conditions and behaviors that characterize households when they lack financial resources to meet basic food needs. Sleep duration, efficiency, wakefulness after sleep onset (WASO), and variability in sleep duration were measured via actigraphy. Sleep quality was assessed via sleep diary. Sleep outcomes were analyzed as a function of FI, adjusting for covariates. Psychological distress was tested as a potential mediator. Results: Greater FI was associated with shorter actigraphy-assessed sleep duration (B = -2.44; SE = 1.24; i.e., 24 minutes shorter for the most as compared to least insecure group), poorer sleep efficiency (B = -.27; SE = .13); p's < .05), and poorer subjective sleep quality (B = -.03; SE = .01; p < .01). Greater FI was also associated with greater likelihood of short (<7 hours; OR = 1.11; CI: 1.02-1.21) and long sleep (>9 hours; OR = 1.19; CI: 1.01-1.39), compared to the recommended sleep duration of 7-9 hours. Psychological distress partially mediated the association between FI and subjective sleep quality. Conclusions: Addressing or mitigating food insecurity may present a novel opportunity for improving sleep health among low-income populations.

RESUMO

BACKGROUND: Aspects of sexual identity development, including integration into gay community, have been found to be associated with sexual risk behavior among men who have sex with men (MSM), but not in the Middle East. METHOD: Drawing on the minority stress model and integrated theory of health behavior, we examined the relationships between measures of sexual identity development and HIV protective behaviors (condomless anal sex and HIV testing) and the mediating roles of HIV knowledge, peer judgmentalism, and discrimination, in a sample of 226 young MSM in Beirut, Lebanon. A cross-sectional, mediation analysis was conducted using a bootstrapping approach and logistic regression models. RESULTS: Fifteen percent of the sample reported recent condomless anal sex with partners whose HIV status was positive or unknown, and 82.3% had ever been tested for HIV. Multivariate logistic regression analysis showed that greater integration into the gay community was significantly associated with having recent condomless anal sex with positive/unknown HIV status partners and having any history of HIV testing, after controlling for covariates. Knowledge of HIV risk was associated with gay integration as well as both condomless anal sex with positive or unknown HIV status partners and any history of HIV testing, but it only served as a (partial) mediator of HIV testing. Peer judgmental communication about sex and sexuality-related discrimination were related in bivariate analysis to gay integration and condomless anal sex, but they too did not prove to be significant mediators of the relationship between these two constructs. CONCLUSION: These findings highlight the potential sexual health benefits and vulnerabilities associated with increased integration into the gay community for young MSM in Beirut and the need to better understand how to increase HIV knowledge while limiting its potential to increase sexual risk behavior.

RESUMO

Background: Research has demonstrated the adverse impact that discrimination has on physical and mental health. However, few studies have examined the association between discrimination and symptoms of posttraumatic stress disorder (PTSD). There is evidence that African Americans experience higher rates of PTSD and are more likely to develop PTSD following trauma exposure than Whites, and discrimination may be one reason for this disparity. Purpose: To examine the association between discrimination and PTSD among a cross-sectional sample largely comprising African American women, controlling for other psychosocial stressors (psychological distress, neighborhood safety, crime). Methods: A sample of 806 participants was recruited from two low-income predominantly African American neighborhoods. Participants completed self-report measures of PTSD symptoms, perceived discrimination, perceived safety, and psychological distress. Information on neighborhood crime was obtained through data requested from the city. Multivariate linear regression models were estimated to assess adjusted relationships between PTSD symptoms and discrimination. Results: Discrimination was significantly associated with PTSD symptoms with a small effect size, controlling for relevant sociodemographic variables. This association remained consistent after controlling for psychological distress, perceived safety, and total neighborhood crime. There was no evidence of a gender by discrimination interaction. Participants who experienced any discrimination were significantly more likely to screen positive for PTSD. Conclusions: Discrimination may contribute to the disparate rates of PTSD experienced by African Americans. PTSD is associated with a range of negative consequences, including poorer physical health, mental health, and quality of life. These results suggest the importance of finding ways to promote resilience in this at-risk population.

RESUMO

During the 1990s, the U.S. Department of Housing and Urban Development awarded more than $6 billion in competitive grants called HOPE VI to spur neighborhood redevelopment. We add to HOPE VI research by examining the impacts of a large set of public-private real estate investments, including HOPE VI, made over a 16-year period in a distressed Pittsburgh neighborhood called the Hill District. Specifically, we estimate the effects of the $468 million additional public-private investments that Hill District received compared to a demographically similar neighborhood on sale prices, rental prices, and crime. We find large and statistically significant impacts of the public-private investments on residential sales prices, commercial sales prices, and on rental prices, but only a marginally significant yet meaningful decline in non-violent arrests. For each additional $10 million of public-private investment, we find a 0.95 percent increase in residential sales prices, 2.7 percent increase in commercial sales prices, and 0.55 percent increase in rental prices. Because there was an accumulated difference over 16 years of $468 million in the amount of public-private investment across the two neighborhoods we examine, these percentage increases amount to large changes in real estate prices over that time. Commercial real estate investors and homeowners benefited the most, followed by residential landlords. Our analyses imply cities should anticipate the potential impacts of major neighborhood investment on low-income households, especially unsubsidized renters that most directly experience the brunt of rising rents.

RESUMO

Black people living with HIV (BPLWH) are less likely to adhere to antiretroviral treatment than are members of other racial/ethnic groups. Data were combined from two studies of BPLWH (n = 239) to estimate adherence trajectories using a semiparametric, group-based modeling strategy over three time-points (spanning 6 months). Analyses identified three groups of individuals (high-stable, moderately low-stable, low-decreasing). Multinomial logistic regressions were used to predict trajectory membership with multiple levels of socio-ecological factors (structural, institutional/health system, community, interpersonal/network, individual). Older age was associated with being in the high-stable group, whereas substance use, lower perceived treatment effectiveness, and lower quality healthcare ratings were related to being in the moderately low-stable group. In sum, multiple socio-ecological factors contribute to adherence among BPLWH and thus could be targeted in future intervention efforts.

RESUMO

OBJECTIVE: Pain affects millions of American adults. However, individuals from socioeconomically disadvantaged groups experience higher rates of pain, and individuals from racial/ethnic minorities report greater pain severity and pain-related disability. Some studies find an association between neighborhood socioeconomic status and pain. The present study aimed to further understand the association between neighborhood disadvantage and pain, including the role of objective (e.g., crime rates) and subjective neighborhood characteristics (e.g., perceived safety, neighborhood satisfaction), and to examine sleep and psychological distress as potential mediators of these associations. METHODS: The sample included 820 participants from two predominantly African American socioeconomically disadvantaged neighborhoods. Trained data collectors interviewed participants on a number of self-report measures, and objective neighborhood characteristics were obtained from city crime data and street segment audits. RESULTS: Subjective characteristics, specifically perceived infrastructure and perceived safety, were associated with pain. Based on bootstrapped regression models, sleep efficiency and psychological distress were tested as mediators of the association between these neighborhood factors and pain. Results of mediation testing indicated that psychological distress served as a significant mediator. Though sleep efficiency was not a mediator, it had a significant independent association with pain. CONCLUSIONS: Understanding the contribution of sleep problems and psychological distress to pain among at-risk individuals living in disadvantaged neighborhoods is important to identifying ways that individual- and neighborhood-level interventions may be leveraged to reduce pain-related disparities.

RESUMO

BACKGROUND: Evidence-based HIV treatment adherence interventions have typically shown medium-sized effects on adherence. Prior evidence-based HIV treatment adherence interventions have not been culturally adapted specifically for Black/African Americans, the population most affected by HIV disparities in the USA, who exhibit lower adherence than do members of other racial/ethnic groups. PURPOSE: We conducted a randomized controlled trial of Rise, a 6-month culturally congruent adherence counseling intervention for HIV-positive Black men and women. METHODS: Rise was delivered by a trained peer counselor who used a problem-solving approach to address culturally congruent adherence barriers (e.g., medical mistrust, HIV stigma) and assisted with linkage to supportive services. A total of 215 participants were randomized to the intervention group (n = 107) or a wait-list control group (n = 108). Adherence was assessed daily via electronic monitoring. RESULTS: In a repeated measures multivariate logistic regression model of dichotomous adherence (using a clinically significant cutoff of 85% of doses taken), adjusted for sociodemographic and medical covariates, adherence in the intervention group improved over time relative to the control group, (OR = 1.30 per month (95% CI = 1.12-1.51), p < 0.001), representing a large cumulative effect after 6 months (OR = 4.76, Cohen's d = 0.86). CONCLUSIONS: Rise showed a larger effect on adherence than prior HIV adherence intervention studies. For greater effectiveness, interventions to improve adherence among Black people living with HIV may need to be customized to address culturally relevant barriers to adherence.

RESUMO

With depression known to impede HIV care adherence and retention, we examined whether depression alleviation improves these disease management behaviors. A sample of 1028 depressed HIV clients in Uganda enrolled in a cluster randomized controlled trial of two depression care models, and were surveyed over 12 months. Serial regression analyses examined whether depression alleviation was associated with self-reported antiretroviral therapy (ART) adherence and clinic attendance at month 12, and whether these relationships were mediated by self-efficacy and motivation. Among those with major depression, depression alleviation was associated with better ART adherence and clinic attendance at month 12; these relationships were fully mediated by self-efficacy at month 12, while adherence motivation partially mediated the relationship between depression alleviation and ART adherence. When both mediators were entered simultaneously, only self-efficacy was a significant predictor and still fully mediated the relationship between depression alleviation and adherence. These findings suggest that depression alleviation benefits both ART adherence and clinic attendance, in large part through improved confidence and motivation to engage in these disease management behaviors.
