Abstract
Background HIV disproportionately affects sexual minority men, and developing strategies to reduce transmission risk is a public health priority. Purpose The goal was to empirically test a newly developed, Information, Motivation, Behavioral skills (IMB) theoretically derived, online HIV sexual risk reduction intervention (called HINTS) among a sample of sexual minority men living with HIV. Methods Participants were 167 men randomized to either the four-session online HINTS intervention or to a time-matched, online control condition. Participants were assessed at baseline and at 6-month follow-up for demographic, medical and psychosocial factors, and sexual risk behavior. Analyses examined group differences in incidence rates of condomless anal sex (CAS) at follow-up with all male sex partners and by partner serostatus, either seroconcordant or serodiscordant for HIV infection. Results Men assigned to the HINTS intervention reported decreased CAS with serodiscordant partners, a behavior that confers high risk of HIV transmission, compared to the control group. Men assigned to the HINTS intervention also reported increased CAS with seroconcordant partners, a behavior indicative of serosorting. Although the IMB model did not appear to mediate these intervention effects, some IMB components were associated with behavioral outcomes at 6-month follow-up. Conclusions A new group-based sexual risk reduction intervention conducted exclusively online was successful in reducing HIV transmission risk behavior in a sample of gay and bisexual men living with HIV. Future work should consider utilizing this intervention with other groups living with HIV, perhaps in combination with biomedical HIV prevention strategies.

Abstract
BACKGROUND Limited access to resources can significantly impact health behaviors. Previous research on food insecurity and HIV has focused on establishing the relationship between lacking access to nutritious food and antiretroviral (ARV) medication non-adherence in a variety of social contexts. PURPOSE This study aims to determine if several aspects of food insecurity co-occur with missed doses of medication on a daily basis among a sample of people living with HIV who have recently experienced hunger. METHODS The current study utilized a prospective, observational design to test the daily relationship between food insecurity and medication non-adherence. Participants were followed for 45 days and completed daily assessments of food insecurity and alcohol use via interactive text message surveys and electronic medication adherence monitoring using the Wisepill. RESULTS Fifty-nine men and women living with HIV contributed a total of 2,655 days of data. Results showed that severe food insecurity (i.e., hunger), but not less severe food insecurity (i.e., worrying about having food), significantly predicted missed doses of medication on a daily level. Daily alcohol use moderated this relationship in an unexpected way; when individuals were hungry and drank alcohol on a given day, they were less likely to miss a dose of medication. CONCLUSIONS Among people living with HIV with recent experiences of hunger, this study demonstrates that there is a daily relationship between hunger and non-adherence to antiretroviral therapy. Future research is needed to test interventions designed to directly address the daily relationship between food insecurity and medication non-adherence.

Abstract
Disclosure of HIV-positive status to sex partners is critical to protecting uninfected partners. In addition, people living with HIV often risk criminal prosecution when they do not inform sex partners of their HIV status. The current study examined factors associated with nondisclosure of HIV status by men living with HIV in Atlanta, GA (92% African African, mean age = 43.8), who engage in condomless sex with uninfected sex partners. Sexually active HIV-positive men (N = 538) completed daily electronic sexual behavior assessments over the course of 28 days and completed computerized interviews, drug testing, medication adherence assessments, and HIV viral load retrieved from medical records. Results showed that 166 (30%) men had engaged in condomless vaginal or anal intercourse with an HIV-uninfected or unknown HIV status sex partner to whom they had not disclosed their HIV status. Men who engaged in nondisclosed condomless sex were less adherent to their HIV treatment, more likely to have unsuppressed HIV, demonstrated poorer disclosure self-efficacy, enacted fewer risk reduction communication skills, and held more beliefs that people with HIV are less infectious when treated with antiretroviral therapy. We conclude that undisclosed HIV status is common and related to condomless sex with uninfected partners. Men who engage in nondisclosed condomless sex may also be more infectious given their nonadherence and viral load. Interventions are needed in HIV treatment as prevention contexts that attend to disclosure laws and enhance disclosure self-efficacy, improve risk reduction communication skills, and increase understanding of HIV infectiousness.

Online Partner Seeking and Sexual Risk Among HIV+ Gay and Bisexual Men: A Dialectical Perspective. ARCHIVES OF SEXUAL BEHAVIOR 2017; 46:1079-1087. [PMID: 27671781 DOI: 10.1007/s10508-016-0833-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Revised: 07/09/2016] [Accepted: 08/08/2016] [Indexed: 06/06/2023]
Abstract
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.

Abstract
In the U.S., there has been a rise in overweight and obesity among persons living with HIV (PLWH). The aim of this study was to examine dietary intake and body mass index (BMI) in PLWH in Atlanta Georgia relative to the U.S. POPULATION Dietary intake among PLWH was compared with recommended standards as well as estimated dietary intake for adults in the U.S. Over 31% of the study participants were overweight [BMI = 25-29.9 kg/m2], and 33.1% obese [BMI ≥ 30 kg/m2]. Results indicated significant dietary differences between participants in our sample and U.S. daily recommendations for adults as well as estimated intakes of the U.S. POPULATION Both males and females consumed more percentage of energy from fat and less fiber as well as fruit and vegetables servings than what is recommended. Results suggest that overweight and obesity are an additional health burden to PLWH in our sample and that their daily dietary practices are not meeting the U.S. government-recommended nutritional standards.

Sexual Behaviors and Transmission Risks Among People Living with HIV: Beliefs, Perceptions, and Challenges to Using Treatments as Prevention. ARCHIVES OF SEXUAL BEHAVIOR 2016; 45:1421-30.

Abstract
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.

Abstract
Limited health literacy has been shown to contribute to poor adherence to antiretroviral therapy (ART) in people living with HIV/AIDS. Given the mixed results of previous interventions for people with HIV and low health literacy, investigating possible targets for improved adherence is warranted. The present study aims to identify the correlates of optimal and suboptimal outcomes among participants of a recent skills-based medication adherence intervention. This secondary analysis included 188 men and women living with HIV who had low health literacy and who had complete viral load data. Adherence was assessed by unannounced pill count and follow-up viral loads were assessed by blood draw. Results showed that higher levels of health literacy and lower levels of alcohol use were the strongest predictors of achieving HIV viral load optimal outcomes. The interplay between lower health literacy and alcohol use on adherence should be the focus of future research.

Abstract
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.

Abstract
Food insecurity is associated with HIV treatment non-adherence and poor health outcomes for people living with HIV/AIDS. Given the poor nutritional status common to people who drink alcohol, food insecurity may be particularly problematic for HIV positive individuals who drink alcohol. To examine food insecurity among HIV positive men and women who drink alcohol and its association with antiretroviral therapy (ART) adherence, health outcomes and health service utilization. Adults living with HIV (N = 183) in Atlanta, Georgia who reported alcohol use in the previous week and were receiving ART participated in a 12-month cohort. Participants were recruited from infectious disease clinics and social services to complete computerized interviews, monthly-unannounced pill counts to monitor ART adherence, and daily cell-phone delivered interactive-text assessments for alcohol use. Forty-three percent of participants experienced food insecurity during at least one month of the study period. Food insecurity was independently associated with suboptimal ART adherence and less suppressed HIV viral load over. Individuals who experienced food insecurity also had histories of more medical and psychiatric hospitalizations, and greater mental health problems. Food insecurity is prevalent among alcohol using people receiving ART and food insecurity is associated with treatment non-adherence, poor health outcomes, and increased medical and psychiatric hospitalizations.

Abstract
BACKGROUND Substance use is a known predictor of poor adherence to antiretroviral therapies (ART) in people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome. Less studied is the association between substance use and treatment outcomes, namely, suppression of HIV replication. METHODS Adults living with HIV (N = 183) who reported alcohol use in the previous week and receiving ART were observed over a 12-month period. Participants completed computer interviews, monthly unannounced pill counts to monitor ART adherence, and daily cell-phone delivered interactive-text assessments for alcohol use. HIV viral load was collected at baseline and 12-month follow-up from medical records. Analyses compared participants who had undetectable HIV viral loads at baseline and follow-up (sustained viral suppression) to those with unsustained viral suppression. Analyses also compared participants who were adherent to their medications (>85 % pills taken) over the year of observation to those who were nonadherent. RESULTS Fifty-two percent of participants had unsustained viral suppression; 47 % were ART nonadherent. Overall results failed to demonstrate alcohol use as a correlate of sustained viral suppression or treatment adherence. However, alcohol use was associated with nonadherence among participants who did not have sustained viral suppression; nonadherence in unsustained viral suppression patients was related to drinking on fewer days of assessment, missing medications when drinking, and drinking socially. CONCLUSIONS Poor HIV treatment outcomes and nonadherence were prevalent among adults treated for HIV infection who drink alcohol. Drinking in relation to missed medications and drinking in social settings are targets for interventions among alcohol drinkers at greatest risk for poor treatment outcomes.

Abstract
INTRODUCTION Food insecurity is a well-established predictor of poor health outcomes. Antiretroviral therapies (ARTs) that should be taken with food to increase bioavailability may further challenge food insecure patients. This study examined factors associated with antiretroviral adherence and HIV viral suppression among people living with HIV who are food insecure and prescribed medications that require food. METHODS A community sample of 313 men and 105 women who experienced food insecurity in the previous month and were currently taking ART completed computerized interviews, urine screening for drug use, prospective biweekly unannounced pill count adherence assessments, and obtained their HIV viral load and CD4 cell counts from medical records. RESULTS Individuals taking ART regimens that should be taken with food were significantly more likely to be unemployed, were living longer with an HIV diagnosis, had lower CD4 cell counts, poorer HIV suppression, and endorsed more beliefs that taking medications was necessary for their health. Multivariable regression models controlling for potential confounding factors showed that receiving ART that requires food was significantly related to poorer ART adherence and unsuppressed HIV in this food insecure sample. CONCLUSION People living with HIV who are food insecure likely experience multiple facets of poverty that challenge their medication adherence, but food insecurity is the only such factor that is directly related to the pharmacokinetics of some antiretroviral medications. Achieving optimal treatment outcomes for HIV infection will require routine assessment of access to food when determining patient-tailored ART regimens.

Abstract
BACKGROUND Co-infection with human immunodeficiency virus (HIV) and Hepatitis-C virus (HCV) poses a significant threat to personal and public health. Substance use among co-infected persons leads to increased morbidity and mortality. The purpose of this study is to examine the continued substance use of people living with HIV-HCV co-infection and receiving antiretroviral therapy (ART). METHODS Individuals living with HIV infection in Atlanta, GA and currently receiving ART (N = 678) completed audio-computer-assisted self-interviews for demographic, health, and behavior characteristics; unannounced pill counts to assess ART adherence over one month; finger-stick blood specimens collected for HCV antibody testing and urine specimens for drug use screening; and obtained HIV viral load and CD4 cell counts from their medical provider. We performed cross-sectional analyses for behavioral and biological markers of health, health behaviors, and substance use. RESULTS Among participants, 131 (19%) were HIV-HCV co-infected; 53% were HIV-mono-infected, and 60% of HIV-HCV co-infected participants tested positive for use of at least one non-alcohol drug: tetrahydrocannabinol (THC) and cocaine were most prevalent. HIV-HCV co-infected individuals were older, with no other significant differences. Within the HIV-HCV co-infected participants, drug users (N = 87) did not differ from non-drug users (N = 53) in terms of ART adherence. However, drug users were significantly more likely to have uncontrolled HIV (17%) compared with those who did not test drug positive (4%). CONCLUSIONS Substance use is prevalent in persons with HIV-HCV co-infection and may interfere with ART. Research with a larger and more representative sample is needed to replicate and confirm these results.

Abstract
BACKGROUND Food insecurity is a known barrier to medication adherence among people living with HIV. Antiretroviral therapies (ART) that require food likely pose added challenges to patients who do not have reliable access to food. This study examines the health implications of prescribing ART that requires food to patients who are food insecure. METHOD A community sample of 538 men and 221 women currently taking ART to treat their HIV infection completed computerized interviews, biweekly unannounced pill count adherence assessments, and obtained their HIV RNA (viral load) and CD4 cell count from medical records. RESULTS Sixty-three percent of participants experienced at least 1 indicator of food insecurity during the previous month, of which 274 (57%) were prescribed an ART regimen that requires food. Among participants who were food insecure, individuals taking ART requiring food indicated significantly greater HIV symptoms, had lower CD4 cell counts, and poorer HIV suppression. For participants who were food secure, those taking ART that requires food were significantly less adherent than those whose ART regimen does not require food. CONCLUSIONS People living with HIV who experience food insecurity are significantly more likely to be prescribed ART regimens that require food and experience poorer treatment outcomes. Determination of optimal ART regimens should take patient access to food into account and treatment guidelines should explicitly highlight the importance of food access in selecting ART regimens.

Abstract
Local genital tract inflammation stimulates leukocyte activity and causes HIV shedding, potentially increasing HIV sexual infectiousness. Although there are available clinical markers for genital tract inflammation, such as urinary leukocyte esterase, none have yet been examined in relation to HIV sexual risk behaviours. We sought to examine the association between urinary leukocyte esterase and sexual practices. Sexually active men living with HIV and receiving antiretroviral therapy (ART, N = 290) provided urine specimens and completed behavioural health assessments. HIV RNA tests and CD4 cell counts were abstracted from medical records. Urine specimens were analysed for leukocyte esterase using a standard point-of-care dipstick test. Thirty-one (10.6%) participants tested positive for leukocyte esterase. Logistic regression models did not indicate differences between men with elevated and un-elevated leukocyte activity on demographic, health, recent sexually transmitted infection symptoms and diagnoses or substance use. However, men with elevated leukocyte activity indicated significantly greater sexual behaviour in the previous three months, including more recent unprotected sexual intercourse. A simple over-the-counter urine test may serve as an indicator of sexual HIV infectiousness to inform further evaluation and treatment of genital tract inflammation, as well as condom use decisions during times of increased genital tract inflammation.

Abstract
BACKGROUND Antiretroviral therapy (ART) adherence is key to successful treatment of HIV infection and alcohol is a known barrier to adherence. Beyond intoxication, ART adherence is impacted by beliefs that mixing alcohol and medications is toxic. PURPOSE To examine prospective relationships of factors contributing to intentional medication non-adherence when drinking. METHODS People who both receive ART and drink alcohol (N = 178) were enrolled in a 12-month prospective cohort study that monitored beliefs about the hazards of mixing ART with alcohol (interactive toxicity beliefs), alcohol consumption using electronic daily diaries, ART adherence assessed by both unannounced pill counts and self-report, and chart-abstracted HIV viral load. RESULTS Participants who reported skipping or stopping their ART when drinking (N = 90, 51 %) demonstrated significantly poorer ART adherence, were less likely to be viral suppressed, and more likely to have CD4 counts under 200/cc(3). Day-level analyses showed that participants who endorsed interactive toxicity beliefs were significantly more likely to miss medications on drinking days. CONCLUSIONS Confirming earlier cross-sectional studies, the current findings from a prospective cohort show that a substantial number of people intentionally skip or stop their medications when drinking. Interventions are needed to correct alcohol-related interactive toxicity misinformation and promote adherence among alcohol drinkers.

Abstract
OBJECTIVES The success of antiretroviral therapy (ART) for treating HIV infection is now being turned towards HIV prevention. The Swiss Federal Commission for HIV/AIDS has declared that HIV-positive persons who are treated with ART, have an undetectable viral load, and are free of co-occurring sexually transmitted infections (STIs) should be considered noninfectious for sexual transmission of HIV. This study examined the implications of these assumptions in a sample of HIV-positive individuals who drink alcohol. METHODS People living with HIV/AIDS (n = 228) were recruited through community sampling. They completed confidential computerized interviews and underwent monthly unannounced pill counts for ART adherence. HIV viral loads were obtained from medical records. RESULTS One hundred and eighty-five HIV-positive drinkers were currently receiving ART and 43 were untreated. Among those receiving ART, one in three were not virally suppressed and one in five had recently been diagnosed with an STI. Adherence was generally suboptimal, including among those assumed to be less infectious. As many as one in four participants reported engaging in unprotected intercourse with an HIV-uninfected partner in the past 4 months. There were few associations between assumed infectiousness and sexual practices. CONCLUSIONS Less than half of people who drank alcohol and took ART met the Swiss criteria for noninfectiousness. Poor adherence and prevalent STI threaten the long-term potential of using ART for prevention. In the absence of behavioral interventions, the realities of substance use and other barriers call into question the use of ART as prevention among alcohol drinkers.

Abstract
Affordable and effective antiretroviral therapy (ART) adherence interventions are needed for many patients to promote positive treatment outcomes and prevent viral resistance. We conducted a two-arm randomized trial (n = 40 men and women receiving and less than 95% adherent to ART) to test a single office session followed by four biweekly cell phone counseling sessions that were grounded in behavioral self-management model of medication adherence using data from phone-based unannounced pill counts to provide feedback-guided adherence strategies. The control condition received usual care and matched office and cell phone/pill count contacts. Participants were baseline assessed and followed with biweekly unannounced pill counts and 4-month from baseline computerized interviews (39/40 retained). Results showed that the self-regulation counseling delivered by cell phone demonstrated significant improvements in adherence compared to the control condition; adherence improved from 87% of pills taken at baseline to 94% adherence 4 months after baseline, p < 0.01. The observed effect sizes ranged from moderate (d = 0.45) to large (d = 0.80). Gains in adherence were paralleled with increased self-efficacy (p < 0.05) and use of behavioral strategies for ART adherence (p < 0.05). We conclude that the outcomes from this test of concept trial warrant further research on cell phone-delivered self-regulation counseling in a larger and more rigorous trial.

Abstract
OBJECTIVE To examine the association of social, health, and poverty-related stressors in relation to antiretroviral therapy adherence in a sample of people with low-literacy living with HIV/AIDS in the southeastern United States. Emotional distress is among the more common factors associated with HIV treatment adherence. Typical barriers to adherence may be overshadowed by poverty experiences in the most disadvantaged populations of people living with HIV/AIDS, such as people with lower-literacy skills. METHODS One hundred eighty-eight men and women living with HIV/AIDS who demonstrated poor health literacy completed measures of social and health-related stress, indicators of extreme poverty, as well as other factors associated with nonadherence. HIV treatment adherence was monitored prospectively, using unannounced pill counts. RESULTS Two-thirds of the sample demonstrated adherence <85% of pills taken. Multivariable analyses showed that food insufficiency and hunger predicted antiretroviral therapy nonadherence over and above depression, internalized stigma, substance use, and HIV-related social stressors. CONCLUSIONS Interventions for HIV treatment nonadherence with the most socially disadvantaged persons in developed countries should be reconceptualized to directly address poverty, especially food insufficiency and hunger, as both a moral and public health imperative.

Abstract
HIV transmission may be prevented by effectively suppressing viral replication with antiretroviral therapy (ART). However, adherence is essential to the success of ART, including for reducing HIV transmission risk behaviors. This study examined the association of nonadherence versus adherence with HIV transmission risks. Men (n = 226) living with HIV/AIDS and receiving ART completed confidential computerized interviews and telephone-based unannounced pill counts for ART adherence monitoring. Data were collected between January 2008 and June 2009. Results showed that nonadherence to ART was associated with greater number of sex partners and engaging in unprotected and protected anal intercourse. These associations were not moderated by substance use. The belief that having an undetectable viral load leads to lower infectiousness was associated with greater number of partners, including nonpositive partners, and less condom use. Men who had an undetectable viral load and believed that having an undetectable viral load reduces their infectiousness, were significantly more likely to have contracted a recent STI. Programs aimed at testing and treating people living with HIV/AIDS for prevention require attention to adherence and sexual behaviors.
