RESUMO

Food insecurity is an established barrier to antiretroviral therapy (ART) adherence among people living with HIV (LWHIV). While insufficient access to food reliably impedes medication adherence, the link between food insecurity and ART nonadherence has not been fully explained. In addition, depression is reliably associated with both food insecurity and ART nonadherence, but again the link between food insecurity and depression is not understood. A potential explanatory mechanism in the associations among food insecurity, depression and ART nonadherence is the experience of food insecurity stigma (FI-stigma). The current study tested FI-stigma in relation to depression as explanatory mechanisms in the association between food insecurity and ART nonadherence. Men and women (n = 495) LWHIV in the southeastern United States completed confidential surveys that included measures of food insecurity, FI-stigma, depression, and ART adherence. Results from the serial mediation model indicated significant direct effects of food insecurity and depression on ART adherence. In addition, food insecurity was indirectly associated with ART adherence through FI-stigma and depression symptoms. Results suggest that the stigmatization of food insecurity predicts increased depression which in turn predicts ART nonadherence, with both FI-stigma and depression symptoms partially mediating the relationship between food insecurity and ART nonadherence. Interventions aimed to reduce food insecurity should include it's associated stigma to improve treatment adherence among people LWHIV.

RESUMO

Cross-sectional studies have reported that people living with HIV experienced disruptions to social relationships and healthcare during the first year of the COVID-19 pandemic. Furthermore, individuals with less trust in public health sources of COVID-19 information as well as those who held greater COVID-19 prejudicial attitudes experienced greater healthcare disruptions in the early months of COVID-19. To examine changes in trust and prejudicial attitudes in relation to healthcare disruptions during the first year of COVID-19, we followed a closed cohort of 115 men and 26 women ages 18 to 36 living with HIV over the first year of the COVID-19 pandemic. Findings confirmed that a majority of individuals continued to experience disruptions to their social relationships and healthcare over the course of the first year of COVID-19. In addition, trust in COVID-19 information from the CDC and state health department diminished over the year as did COVID-19 prejudicial attitudes. Regression models showed that lower trust in the CDC and health department and greater prejudicial attitudes toward COVID-19 early in the pandemic predicted greater healthcare disruptions over the year. In addition, greater trust in the CDC and health department early in COVID-19 predicted better antiretroviral therapy adherence later in the year. Results support an urgent need to regain and sustain trust in public health authorities among vulnerable populations.

RESUMO

This study tested the hypothesis that the co-occurrence of alcohol use and depressive symptoms predicts HIV suppression and antiretroviral therapy (ART) adherence among people living with HIV. Baseline cross-sectional results showed a significant interaction between depressive symptoms and alcohol use in predicting HIV suppression; individuals who drank more alcohol and had higher depressive symptoms demonstrated poorer HIV suppression relative to those who had fewer depressive symptoms. In a one-year longitudinal analysis of ART adherence, alcohol use and depressive symptoms measured in daily text-message assessments demonstrated that neither alcohol use nor depressive symptoms alone predicted ART adherence. However, the intersection of alcohol use on days when experiencing depressive symptoms did significantly predict ART non-adherence, for both moderate and heavy alcohol drinkers. Findings suggest that the co-occurrence of alcohol use and depressive symptoms is a robust predictor of poor HIV treatment outcomes.

RESUMO

Patient initiated decisions to forgo taking medications (i.e. intentional nonadherence) pose significant challenges to managing chronic health conditions. Identifying factors and their underlying mechanisms that impede medication adherence is essential to designing treatment improvement interventions. This study tested a conceptual model that posits the effects of perceived sensitivity to medicines on adherence can be explained by the experience of side-effects, leading to intentionally nonadherent behaviors. Patients receiving HIV care in the southern United States (N = 209) completed measures of perceived sensitivity to medicines, antiretroviral therapy (ART) side-effects, intentional nonadherence and overall adherence. Patients also provided consent to access their electronic medical records to collect subsequent reports of HIV viral load tests. Results indicated that more than one in four participants were intentionally nonadherent to ART. Mediation modeling showed that perceived sensitivity to medicines was associated with greater experience of ART side-effects and intentional nonadherence, which impacted overall ART adherence and HIV viral load. There were also significant indirect effects of perceived sensitivity to medicines on HIV viral load through side-effects and intentional nonadherence. Patients with increased perceived sensitivity to medicines are at risk for poor treatment outcomes and these negative outcomes are partly explained by experiencing greater side-effects and intentional nonadherence.

RESUMO

BACKGROUND: SARS-CoV-2 infection (COVID-19) is potentially severe for individuals with compromised immune systems, including people living with HIV. Along with the direct health threats of COVID-19, there are disruptions to social relationships and health services resulting from mitigation efforts instituted by public health authorities. This study examined the relationship between trust in the government and trust in COVID-19 health information from the US CDC, state health departments, and social media on the experience of COVID-19 social and health services-related disruptions. METHODS: People living with HIV (N = 459) recruited through social media advertisements and chain referrals completed confidential surveys delivered through an online platform. RESULTS: Participants experienced high-levels of disruptions to social relationships and health services attributable to COVID-19 mitigation efforts. We also observed high-rates of inaccurate information and low-levels of trust in government and sources of COVID-19 information. Greater disruptions to social relationships were predicted by more concern about oneself and others contracting COVID-19, whereas disruptions to health services were predicted by greater concern for oneself contracting COVID-19, greater general medical mistrust, and less trust in information from the CDC. CONCLUSIONS: Findings have implications for the necessity of rebuilding public trust in credible sources of health information and stepping up efforts to counter sources of inaccurate information.

RESUMO

BACKGROUND: Lower health literacy is associated with poorer health outcomes in people living with HIV (PLWH), but the explanatory mechanisms for these associations are not well understood. Factors such as drug use and life chaos may at least in part account for the relationship between lower health literacy and poor health outcomes. The current study tested the hypothesis that lower health literacy would predict drug use, which in turn would predict life chaos, and that all three factors would be related to poorer heath, defined by higher concentrations of HIV viremia. Methods: Patients receiving HIV care (N = 251) at an HIV clinic in the southeastern United States completed computerized interviews and permission to access their medical records. Process modeling tested direct and indirect effects of all variables in a serial mediation model. Results: The direct effects of lower health literacy and drug use were significantly related to HIV viremia. In addition, the indirect effect of health literacy on HIV viremia through drug use was significant. However, results did not demonstrate any effect, direct or indirect, of life chaos on HIV viremia. Conclusion: Findings from this study bolster previous research demonstrating lower health literacy and drug use as barriers to HIV care, and show that lower health literacy impacts HIV viremia, at least in part, through drug use. Interventions aimed to improve HIV treatment outcomes in lower health literacy populations may be enhanced by integrating evidence-based approaches to reducing drug use.

RESUMO

The life-saving effects of antiretroviral therapy (ART) in treating HIV infection are compromised by alcohol use. A growing body of research shows that both unintentional (e.g., memory lapses) and intentional (e.g., forgoing ART to avoid mixing with alcohol) contribute to ART non-adherence. Beliefs that it is harmful to mix alcohol with ART (alcohol-ART interactive toxicity beliefs) contribute to intentional non-adherence, but their role in overall adherence is not clear. This study conducted a clinic-based survey with 100 men and 193 women (mean age = 36) to examine the prevalence of alcohol-ART interactive toxicity beliefs and whether they contribute to treatment non-adherence in South Africa. One in three (36%, n = 106) participants reported no current alcohol use and 64% (n = 187) reported current alcohol use. The majority of participants, including current alcohol drinkers, endorsed beliefs that it is harmful to mix ART and alcohol, with 57% who currently drink reporting that they forgo taking ART when they are drinking. Participants reported being warned not to mix alcohol and ART from family, friends, and health care providers. In addition, 62% of participants who do not drink, as well as 36% of those who do drink, tell others not to mix alcohol and ART. Mediation modelling found that alcohol use directly predicts ART adherence, and that this relationship is partially mediated by alcohol-ART interactive toxicity beliefs. Health care providers can play a critical role in disputing interactive toxicity beliefs and encouraging patients to take ART even when they are drinking.

RESUMO

OBJECTIVES: We aimed to identify individual and sexual partnership characteristics associated with partner notification (PN) among people with STI. We hypothesised that PN would be less likely in more casual sexual partnerships and in partnerships with intimate partner violence (IPV). METHODS: We conducted an observational study among the first 330 patients with STI enrolled in a trial of a behavioural intervention to reduce STI incidence, at a clinic in a poor, Cape Town community. We included 195 index patients (those reporting STI symptoms), and conducted longitudinal analyses using participant-completed questionnaires on the day of diagnosis and 2 weeks later. Using partnership data for five recent sexual partners, we assessed factors associated with reported PN with logistic regressions, adjusting for repeated measurements on the same participant for each partner. RESULTS: The sample included 99 males with 303 partners and 96 females with 158 partners. Males reported perpetrating IPV in 46.2% of partnerships. Females reported being IPV victims in 53.2% of partnerships. Males notified 58.1%, females 75.4% of partners during the 2 weeks following diagnosis. Type of partner was an independent correlate of PN for males and females, with the odds of PN lower in more casual partnerships. For males, reporting physical IPV perpetration in the partnership was an independent correlate of PN. For females, there was no association between IPV victimisation in a partnership and PN. CONCLUSIONS: Efforts to decrease the pool of infectious partners need to have a strong focus on the promotion of PN in casual relationships and one-night stands. IPV was not identified as a barrier to PN. In future, we need to investigate the association between IPV with an objective measure of PN success such as partner testing or treatment, or index patient reinfection.

RESUMO

OBJECTIVES: Novel interventions to address sexual risk taking and slow rates of STIs are urgently needed, in particular among black men who have sex with men (MSM) in the USA. Serosorting, or limiting condomless sex acts to partners of the same HIV status, is commonly practised among MSM, yet can lead to STI and remains largely unaddressed by public health agencies. METHODS: A two-arm, randomised controlled trial was conducted from 2012 to 2015. This trial assessed the effects of a single-session, sexual partner selection and risk decision intervention (experimental arm) versus a single-session, Centers for Disease Control and Prevention-based, sexual risk reduction intervention (control arm) on psychosocial measures, sexual risk taking and STI. RESULTS: At study follow-ups, multiple beneficial changes were observed on sexual risk beliefs measures (ie, changes in serosorting and condom use beliefs, and HIV risk perceptions) and sexual risk taking among the experimental arm relative to the control arm. Overall main effects, however, of the intervention on STI outcomes on year-long follow-ups were non-significant. There was evidence for short-term effects on STI outcomes, and self-report of multiple STIs and STI symptoms demonstrated positive effects over the follow-up period. CONCLUSIONS: Brief interventions to address sexual risk taking can result in short-term beneficial outcomes and can be incorporated into currently existing infrastructure at healthcare agencies. Additional intervention will be necessary for demonstrating long-term results. TRIAL REGISTRATION NUMBER: NCT02128594.

RESUMO

As people living with HIV experience longer life-expectancies resulting from antiretroviral therapy, comorbid conditions are increasing, particularly metabolic disorders. There is potential for psychosocial factors such as stigma experiences, depression, and alcohol use to complicate both HIV infection and metabolic disorders, including diabetes mellitus and hyperlipidemia. While the impact of these psychosocial factors on HIV infection alone are widely studied, their role in potentially complicating HIV co-morbid metabolic conditions has received little attention. This study examined the association between HIV-related stigma and depression, and the potential role of alcohol use as a mediating factor in a clinical sample of patients with comorbid HIV infection and metabolic conditions. Results demonstrated that HIV stigma is associated with depression and this relationship is in part accounted for by alcohol use. Our results indicate that interventions aiming to improve the health of people living with HIV and co-morbid metabolic disorders should prioritize addressing alcohol use as it is related to sources of stress, such as stigma, and depression.

RESUMO

HIV infection is now clinically manageable with antiretroviral therapy (ART). However, a significant number of people with HIV do not benefit from ART because of non-adherence. This study examined the use of adherence strategies and barriers to adherence among persons at substantial risk for developing resistant virus (less than 75% adherent). People living with HIV (n = 556) who were less than 95% adherent to ART completed computerized interviews, were screened for active drug use, provided medical records for HIV viral load, and completed unannounced pill counts to monitor ART adherence and an assessment of adherence barriers. Based on pill counts, participants were defined as severely non-adherent (≤75% medications taken) and moderately non-adherent (>75% and <95% adherent). Results showed a broad array of memory devices were used to no avail across non-adherence groups. Individuals who were severely non-adherent were significantly more likely to attribute missing medications due to substance use and structural barriers, including running out of medications, inability to get to pharmacy, and inability to afford medications. Results suggest that interventions focused on memory lapses will be insufficient and should rather concentrate on substance use treatment and providing case management to resolve structural barriers to adherence.

RESUMO

Antiretroviral therapy (ART) has transformed HIV into a manageable illness. However, high levels of adherence must be maintained. Lack of access to basic resources (food, transportation, and housing) has been consistently associated with suboptimal ART adherence. Moving beyond such direct effects, this study takes a hierarchical resources approach in which the effects of access to basic resources on ART adherence are mediated through interpersonal resources (social support and care services) and personal resources (self-efficacy). Participants were 915 HIV-positive men and women living in Atlanta, GA, recruited from community centers and infectious disease clinics. Participants answered baseline questionnaires, and provided prospective data on ART adherence. Across a series of nested models, a consistent pattern emerged whereby lack of access to basic resources had indirect, negative effects on adherence, mediated through both lack of access to social support and services, and through lower treatment self-efficacy. There was also a significant direct effect of lack of access to transportation on adherence. Lack of access to basic resources negatively impacts ART adherence. Effects for housing instability and food insecurity were fully mediated through social support, access to services, and self-efficacy, highlighting these as important targets for intervention. Targeting service supports could be especially beneficial due to the potential to both promote adherence and to link clients with other services to supplement food, housing, and transportation. Inability to access transportation had a direct negative effect on adherence, suggesting that free or reduced cost transportation could positively impact ART adherence among disadvantaged populations.

RESUMO

For almost two decades, researchers have explored the relationship between online partner seeking (OPS) and HIV/STI transmission risk behavior among men who have sex with men (MSM), including gay- and bisexual-identified men. A dichotomy has emerged with some findings that OPS is associated with greater sexual risk behavior, and a sparser but emerging literature that men may use OPS for sexual risk reduction. This study examined the association between proportion of partners met online and sexual risk behavior in a sample of 170 HIV-positive gay- and bisexual-identified men. Participants completed assessments including psychosocial factors and a comprehensive assessment of sexual behavior, including total number of male partners, and condomless insertive and receptive anal sex with HIV-negative/unknown serostatus partners or HIV-positive male partners. Our findings support taking a dialectical stance and indicate that OPS may impact risk differently given different individual and contextual circumstances.

RESUMO

Alcohol-antiretroviral therapy (ART) interactive toxicity beliefs reflect perceived adverse outcomes of mixing alcohol and ART. Previous research has shown a significant relationship between alcohol-ART interactive toxicity beliefs and ART non-adherence, over and above other correlates of non-adherence such as human immunodeficiency virus (HIV)symptoms and frequency of alcohol use. Most past studies have collected data over extended periods and have not determined if alcohol use and missed medications occur at the day-level among people holding interactive toxicity beliefs. Previous daily analyses, however, have been limited by self-reported adherence and relatively short periods of observation. To address these gaps in the literature, men and women living with HIV in Atlanta, GA, were enrolled in a 45-day observational cohort study. Daily alcohol use was collected using two-way interactive text message surveys and daily adherence was collected via the Wisepill device. Fifty-seven participants completed a measure of alcohol-ART interactive toxicity beliefs and contributed 2565 days of daily data. Participants who endorsed high levels of interactive toxicity beliefs had significantly more days when they missed doses of medication. Alcohol-antiretroviral toxicity beliefs predicted missing doses of medication on days when participants were drinking and on days when they were not drinking. Multilevel multivariate regressions showed that these toxicity beliefs predicted daily missed doses of medication over and above quantity of alcohol consumed, depression and general medication concerns. This study replicates and extends previous literature and indicates the necessity of addressing alcohol-ART toxicity beliefs within adherence interventions.

RESUMO

Gay, bisexual, and other men who have sex with men (MSM) remain the highest risk group for HIV infection. One reason is the increased use of the Internet to meet potential sex partners, which is associated with greater sexual risk behavior. To date, few studies have investigated psychosocial predictors of sexual risk behavior among gay and bisexual men seeking sex partners online. The purpose of the current study was to test a conceptual model of the relationships between trauma symptoms indexed on the event of HIV diagnosis, internalized HIV stigma, and social support on sexual risk behavior among gay and bisexual MSM who seek sex partners online. A sample of 142 gay and bisexual MSM recruited on- and offline completed a comprehensive online assessment battery assessing the factors noted above. A number of associations emerged; most notably internalized HIV stigma mediated the relationship between trauma-related symptoms indexed on the event of HIV diagnosis and sexual risk behavior with HIV-negative and unknown serostatus sex partners. This suggests that gay and bisexual MSM who are in greater distress over their HIV diagnosis and who are more sensitive to HIV stigma engage in more HIV transmission risk behavior. As sexual risk environments expand with the increasing use of the Internet to connect with others for sex, it is important to understand the predictors of sexual risk behavior so that tailored interventions can promote sexual health for gay and bisexual MSM seeking sex online.

RESUMO

Antiretroviral therapy (ART) improves the health of people living with HIV and can reduce infectiousness, preventing HIV transmission. The potential preventive benefits of ART are undermined by beliefs that it is safe to have condomless sex when viral load is below levels of detection (infectiousness beliefs and risk perceptions). In this study, we hypothesized that infectiousness beliefs and HIV transmission risk perceptions would prospectively predict people living with HIV engaging in more condomless sex with HIV-negative and unknown HIV status sex partners. Sexually active HIV-positive men (n = 538, 76 %) and women (n = 166, 24 %) completed computerized interviews of sexually transmitted infection (STI) symptoms and diagnoses, unannounced pill counts for medication adherence, medical chart-abstracted HIV viral load, and 28 daily cell-phone-delivered prospective sexual behavior assessments. Results showed that a total of 313 (44 %) participants had engaged in condomless sex with HIV-negative/unknown status sex partners, and these individuals demonstrated higher rates of STI symptoms and diagnoses. Two-thirds of participants who had condomless sex with HIV-negative/unknown status partners had not disclosed their HIV status. Multivariable logistic regression models showed that beliefs regarding viral load and HIV infectiousness and perceptions of lower risk of HIV transmission resulting from HIV viral suppression predicted condomless sex with potentially uninfected partners over and above sex behaviors with HIV-positive partners and STI symptoms/diagnoses. Interventions that address HIV status disclosure and aggressively treat STI in sexually active people living with HIV should routinely accompany the use of HIV treatments as prevention.

RESUMO

Race-based medical mistrust significantly predicts non-adherence to antiretroviral therapy (ART) in people living with HIV. The current study builds on previous research that shows beliefs about medication necessity (i.e., "My medicines protect me from becoming worse") and concerns (i.e., "Having to take my medicines worries me") mediate the association between race-based medical mistrust and medication adherence. Racial and ethnic minority men and women living with HIV and receiving ART (N = 178) in a southern US city completed computerized measures of demographic and health characteristics, telephone interviews of race-based medical mistrust and medication beliefs, and unannounced phone-based pill counts for ART adherence. Multiple mediation modeling showed that medical mistrust is related to medication necessity and concerns beliefs and ART adherence. Furthermore, medication necessity beliefs predicted ART adherence. The indirect effect of medical mistrust on adherence through medication necessity beliefs was also significant. Results confirm that medication necessity beliefs, although not concerns beliefs, mediate the association between medical mistrust and ART adherence. Medication necessity beliefs offer a viable target for interventions to improve ART adherence in the context of mistrust that patients may have for medical providers and health care systems.

RESUMO

A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

HIV treatment depends on high-levels of antiretroviral therapy (ART) adherence, which is severely impeded by poverty. Men and women living with HIV infection (N = 92) completed computerized interviews of demographic and health characteristics, poverty markers, stressful life events, and life chaos, as well as unannounced pill counts to determine prospective medication adherence and medical record chart abstractions for HIV viral load. Poverty markers were associated with both stressors and chaos, and the direct effects of all three factors predicted ART non-adherence. The multiple mediation model showed that accounting for stressors and chaos resulted in a non-significant association between poverty markers and ART adherence. The indirect effect of poverty markers on adherence through life chaos was significant, whereas the indirect effect of poverty markers on adherence through stressors was not significant. Factors that render HIV-related stress and create chaos offer intervention targets that are more amenable to change than poverty itself.

RESUMO

Beliefs about medication necessity and concerns predict treatment adherence in people with a wide-array of medical conditions, including HIV infection. However, medication beliefs have not been examined in people dually treated with psychotropic medications and antiretroviral therapy. In the current study, we used a prospective design to investigate the factors associated with adherence to psychotropic medications and antiretrovirals among 123 dually treated persons living with HIV. We used unannounced phone-based pill counts to monitor adherence to psychiatric and antiretroviral medications over a 6-week period. Hierarchical regression models included demographic, health and psychosocial characteristics as predictors of adherence followed by medication necessity and concerns beliefs. Results showed that medication necessity beliefs predicted both antiretroviral and psychiatric medication adherence over and above established predictors of adherence. Medication concerns also predicted psychotropic adherence, but not antiretroviral adherence. These models accounted for 31 and 22 % of the variance in antiretroviral and psychotropic adherence, respectively. Findings suggest that the necessity-concerns medication beliefs framework has utility in understanding adherence to multiple medications and addressing these beliefs should be integrated into adherence interventions.
