RESUMO

In December 2021, long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was approved for the prevention of HIV in at-risk adults and adolescents. LAI-PrEP may address adherence issues of daily oral daily PrEP and PrEP stigma. However, studies assessing LAI-PrEP willingness among PrEP naive Black and Hispanic sexual and gender minority (SGM) persons- a group disproportionately impacted by the HIV epidemic in the United States - is rare. To assess the extent of and characteristics of willingness to use LAI-PrEP in a national sample of Black and Hispanic SGM who are self-reported that they have never used PrEP. We analyzed data from a national sample of Black and Hispanic SGM collected between March and August 2020. We used log-binomial regression models to assess characteristics associated with willingness to use LAI-PrEP. Of the overall sample (N = 380), the mean age was 24 (SD = 2.8) and the majority of the sample (54%, n = 205) reported willingness to use LAI-PrEP. In multivariable log-binomial regression models, PrEP stigma was independently associated with less [prevalence ratio (PR) = 0.7, 95% confidence interval (CI) = 0.6, 0.9], while number of sexual partners in the past 12 months was associated with a more willingness to use LAI-PrEP (PR = 1.1, 95% CI = 1.0, 1.2). Our findings highlight the persistence of PrEP stigma as a potential barrier to willingness to use LAI-PrEP in this sample of Black and Hispanic SGM who have never used PrEP. Additional work needs to be done to reduce PrEP stigma more broadly.

RESUMO

Among sexual minority men (SMM), internalized homophobia (IH) has been consistently associated with increased depression symptoms. However, some SMM experiencing IH demonstrate resilience to buffer against depression symptoms. In this analysis, we used the Stress Process Model (SPM) as a conceptual framework to explore individual-level psychosocial resilience (ILPR) factors serving as a buffer of the IH-depression relationship. To utilize the SPM to explore whether four ILPR factors, including volunteerism, optimism, religiosity/spirituality, and global resiliency measure mediate the relationship between IH and depression symptoms among middle-aged and older SMM living with and without HIV. We used exploratory and confirmatory factor analysis to construct measurement models for the four ILPR factors. We examined whether the four ILPR factors mediated the IH-depression relationship. IH was significantly and positively associated with depression symptoms. There was a partial mediation of the IH-depression association by the four ILPR. Specifically, we found statistically significant indirect effects of optimism and the global resilience measure and supporting buffering effects of the IH-depression association. Although, the indirect effects religiosity/spirituality on the IH-depression relationship was significant, it did not support a buffering of effect. The indirect effects of volunteerism were not statistically significant. Our findings highlight the potential role of ILPR factors in the development of resilience against the negative effects of IH. Implications of these results for future research and practice are discussed.

RESUMO

Objectives: Studies have shown that grit-defined as perseverance and passion for achieving one's long-term goals-is associated with improved health outcomes, including lower levels of psychological distress. However, the psychometric properties of the original Grit Scale (Grit-O Scale) has not been validated among sexual minority men (SMM). The present study aimed to validate the Grit-O Scale among a sample of older SMM and assess the relationships between the Grit-O Scale factors and symptoms of psychological distress.Method: We used data from a single visit of participants in the Multicenter AIDS Cohort Study (MACS) Healthy Aging longitudinal study. The sample included 981 older SMM (mean age = 61, SD = 8.5) with and without HIV. We conducted confirmatory factor analysis (CFA) to identify the two factors of the Grit-O Scale: consistency of interest and perseverance of effort. We also conducted a latent profile analysis (LPA) to identify distinct profiles of psychological distress from self-reported scales of depression, anxiety, and perceived stress.Results:The Grit-O Scale showed acceptable reliability estimates for the items with Cronbach's alpha reliability coefficients ranging from 0.77 to 0.82. The CFA identified the two factors of the Grit-O Scale with acceptable model fit (root mean square error of approximation = 0.058 [95% CI = 0.050, 0.067], comparative fit index = 0.95, Tucker-Lewis Index = 0.93, standardized root mean square residual = 0.07). The LPA yielded three mutually exclusive profiles of psychological distress (profile 1: low stress, anxiety, and depression; profile 2: high stress and depression and low anxiety; and profile 3: high stress, anxiety, and depression). In adjusted multinominal logistic regression analysis, we found that both higher levels of consistency of interest and perseverance of effort factors of the Grit-O Scale were significantly associated with decreased odds of being in profiles 2 and 3 compared with being in profile 1.Conclusion: Our findings support the use of the Grit-O Scale among older SMM. Grit factors could explain variability in the negative psychological symptoms among older SMM and warrant further investigation.Supplemental data for this article is available online at http://dx.doi.org/10.1080/13607863.2022.2032594.

RESUMO

BACKGROUND: Social genomics has demonstrated altered inflammatory and type I interferon (IFN) gene expression among people experiencing chronic social adversity. Adverse social experiences such as discrimination and violence are linked to stimulant misuse and HIV, conditions that dysregulate inflammatory and innate antiviral responses, leading to increased HIV viral replication and risk of chronic diseases. PURPOSE: We aimed to determine whether methamphetamine (MA) use, unsuppressed HIV viral load (VL) (≥200 c/mL), and experienced intimate partner violence (IPV) (past 12 months) predicted inflammatory and type I IFN gene expression in HIV-positive Black and Latinx men who have sex with men (MSM). METHODS: Participants were 147 HIV-positive Black and Latinx MSM recruited from the mSTUDY, a cohort of 561 MSM aged 18-45 in Los Angeles, CA, of whom half are HIV-positive and substance-using. Transcriptomic measures of inflammatory and type I IFN activity were derived from RNA sequencing of peripheral blood mononuclear cells and matched to urine drug tests, VL, and survey data across two time points 12 months apart. Analysis used linear random intercept modeling of MA use, unsuppressed VL, and experienced IPV on inflammatory and type I IFN expression. RESULTS: In adjusted models, MA use predicted 27% upregulated inflammatory and 31% upregulated type I IFN expression; unsuppressed VL predicted 84% upregulated type I IFN but not inflammatory expression; and experienced IPV predicted 31% upregulated inflammatory and 26% upregulated type I IFN expression. CONCLUSIONS: In Black and Latinx MSM with HIV, MA use, unsuppressed VL, and experienced IPV predicted upregulated social genomic markers of immune functioning.

RESUMO

Men who have sex with men (MSM) experience high rates of homophobic victimization, which is linked to myriad chronic physical and mental health disparities. Social adversity such as rejection, isolation, and racial discrimination can induce a conserved transcriptional response to adversity (CTRA) involving upregulation of proinflammatory genes and downregulation of type I interferon and antibody synthesis genes. This study specifically examines whether homophobic victimization is associated with expression of CTRA profiles in Black and Latino MSM living in Los Angeles. Analyses linked behavioral survey data with quantified RNA from leukocytes from blood samples of 70 participants over 12 months. CTRA gene expression was increased by 3.1-fold in MSM who experienced homophobic victimization while adjusting for major leukocyte subsets and sociodemographics. Accounting for all these factors, CTRA gene expression was significantly enhanced in MSM who identified as Black compared to Latino. Our findings identify experiences of homophobic victimization as drivers of inflammatory and type I interferon gene expression profiles, which can contribute to physical and mental health challenges in Black and Latino MSM.

RESUMO

We assessed whether disclosure of HIV status is significantly associated with reported HIV sexual risk behaviors among HIV positive Black/African American men who have sex with men (MSM) (Black MSM) in six cities in the USA. Participants from the BROTHERS (HIV Prevention Trials Network [HPTN 061]) study focused on assessing the feasibility and acceptability of a multifaceted HIV prevention intervention to reduce HIV infections among Black MSM enrolled between July 2009 and October 2010. All participants completed a behavioral assessment using an audio computer-assisted self-interview that included questions about HIV status disclosure, HIV sexual risk behaviors, and other behaviors. Biological samples were also collected. This analysis focused on baseline data of HIV-positive Black MSM in the HPTN 061 study. Of the 143 HIV-positive Black MSM (majority ≥ 35 years of age) included in this analysis, 58% reported disclosing their HIV status to their last male anal sex partner. Forty-three percent and 42% reported condomless insertive and receptive anal intercourse respectively with their last male partner; whereas, 17% and 18% of the sample engaged in condomless insertive and receptive anal intercourse with a serodiscordant/unknown status partner, respectively. In multivariable logistic regression models, there was no statistically significant association between HIV status disclosure and condomless insertive anal intercourse (aOR = 0.35, 95% CI 0.11, 1.08; p = 0.30), condomless receptive anal intercourse (aOR = 2.48, 95% CI 0.94, 6.52; p = 0.20), or condomless receptive anal intercourse with a serodiscordant/unknown status partner (aOR = 0.55, 95% CI 0.20, 1.49; p = 0.45). However, HIV status disclosure was significantly associated with lower odds of reporting condomless insertive anal intercourse with a serodiscordant/unknown status partner (aOR = 0.19, 95% CI 0.06, 0.68; p ≤ 0.01). Among this multi-city sample of HIV-positive Black MSM, disclosure of HIV status was common and associated with lower HIV sexual risk behaviors. These findings should motivate and guide research to develop prevention messages to increase HIV status disclosures.

RESUMO

BACKGROUND: The long-term effects of marijuana on cognition, particularly in the context of HIV is not clear, as extant research shows mixed findings. OBJECTIVE: To determine associations between current and cumulative exposure to marijuana and changes in cognitive processing speed and flexibility in 788 HIV-seropositive (HIV+) and 1,132 HIV-seronegative (HIV-) men followed for up to 17 years in the Multicenter AIDS Cohort Study. RESULTS: Among HIV+ men only, current daily marijuana use compared to none-use, was significantly associated with a greater annual percentage decline in cognitive processing speed assessed with the Trail Making Test A (TMTA) (ß=-0.41, 95% confidence interval (CI): -0.88, -0.03, p=0.03)] and Symbol Digit Modalities Test (SDMT) (ß= -0.14, 95% CI: -0.28, -0.01, p=0.04). Further, monthly marijuana use was associated with greater annual percentage decline in cognitive flexibility assessed with the Trail Making Test B (TMTB) (ß= -0.70, 95% CI: -1.34, -0.05; p=0.03] and cognitive processing speed (SDMT) (ß= -0.21, 95% CI: -0.40, -0.01, p=0.03). Among the HIV- men only, each 5-marijuana use-years (equivalent to 5-years of daily marijuana use) was significantly associated with a 0.17 annual percentage decline in cognitive processing speed only (TMTA) (ß= -0.18, 95% CI: -0.36, -0.01; p=0.04). CONCLUSIONS: Our findings suggest that marijuana use, particularly current use, may be associated with worse cognitive processing speed, but the magnitude of the estimates was not clinically meaningful.

RESUMO

Young men in South Africa experience several adverse socio-structural and psychosocial factors that may contribute HIV risk behaviors. This study applied a syndemic framework to explore whether these syndemic factors are interconnected and work in synergy to increase HIV risk behaviors. Five syndemic factors were assessed including: binge drinking, polydrug use, depressive symptoms, violence and food insecurity on two HIV risk behaviors: multiple sex partners and transactional sex. Participants were (N = 1233) young men aged 18-29 years from a township in Cape Town, South Africa. Bivariate logistic regression analysis demonstrated that many of the syndemic factors were related to one another. Pairwise interactions (on an additive scale) among the syndemic factors revealed significant positive interactions between binge drinking and violence on greater odds of reporting multiple sex partners (aOR = 5.10, 95% CI 3.10, 8.29; p = < .001) compared to reporting neither factor. Also, food insecurity and violence (aOR = 2.89, 95% CI 1.63, 5.11; p = < .001) as well as food insecurity and polydrug use (aOR = 2.73, 95% CI 1.54, 4.84; p = < .001) were significantly associated with greater odds of transactional sex compared to reporting neither factor. Our findings highlight a synergistic relationship between some adverse socio-structural and psychosocial factors on HIV risk behaviors. HIV prevention programs that address multiple syndemic factors simultaneously may achieve greater impact on HIV risk reduction.

RESUMO

To construct longitudinal trajectories of marijuana use in a sample of men who have sex with men living with or at-risk for HIV infection. We determined factors associated with distinct trajectories of use as well as those that serve to modify the course of the trajectory. Data were from 3658 [1439 HIV-seropositive (HIV+) and 2219 HIV-seronegative (HIV-)] participants of the Multicenter AIDS Cohort Study. Frequency of marijuana use was obtained semiannually over a 29-year period (1984-2013). Group-based trajectory models were used to identify the trajectories and to determine predictors and modifiers of the trajectories over time. Four distinct trajectories of marijuana use were identified: abstainer/infrequent (65 %), decreaser (13 %), increaser (12 %) and chronic high (10 %) use groups. HIV+ status was significantly associated with increased odds of membership in the decreaser, increaser and chronic high use groups. Alcohol, smoking, stimulant and other recreational drug use were associated with increasing marijuana use across all four trajectory groups. Antiretroviral therapy use over time was associated with decreasing marijuana use in the abstainer/infrequent and increaser trajectory groups. Having a detectable HIV viral load was associated with increasing marijuana use in the increaser group only. Future investigations are needed to determine whether long-term patterns of use are associated with adverse consequences especially among HIV+ persons.

RESUMO

We assessed socio-structural and behavioral correlates of preexposure prophylaxis (PrEP) for HIV infection among a sample of high-risk HIV-negative men who have sex with men (MSM) in Los Angeles, California. Participants from an ongoing 5-year prospective cohort study investigating the direct impacts of substance use on HIV transmission dynamics were enrolled between February 2015 and January 2017. All men completed a computer-assisted self-interview every 6 months that assessed recent (past 6 months) PrEP use and socio-structural and behavioral factors. Of the total 185 MSM (mean age = 29 years) included in the study, majority were African American (40%) or Hispanic (41%) and reported current health insurance coverage (80%). In multivariable analysis using log-binomial regression, having health insurance coverage [adjusted prevalence ratio (aPR) 2.02; 95% confidence interval (CI) 1.01 to 4.01, p = 0.04] was associated with recent PrEP use. Unstable housing (aPR = 0.44, 95% CI 0.22 to 0.90, p = 0.02) was associated with lower PrEP use. Behavioral factors associated with recent PrEP use include sex with a HIV-positive partner (aPR = 3.63, 95% CI 1.45 to 9.10, p = 0.01), having six or more sex partners (aPR = 2.20, 95% CI 1.26 to 3.82, p = <0.01), and popper use (aPR = 2.76, 95% CI 1.58 to 4.84, p = <0.01). In this sample of predominantly racial/ethnic minority MSM, socio-structural and behavioral factors were important factors associated with recent PrEP use. These findings provide considerations for intervention development to promote PrEP use among key groups of MSM.

RESUMO

BACKGROUND: Marijuana use is common among persons living with HIV (PLWH), but studies on its effect on HIV clinical outcomes are limited. OBJECTIVES: We determined the association between marijuana use and HIV viral suppression among PLWH. METHODS: Data came from five repeated cross-sections (2009-2013) of the Florida Medical Monitoring Project, a population-based sample of PLWH in Florida. Data were obtained via interview and medical record abstraction (MRA). Weighted logistic regression models were used to determine the association between marijuana use (past 12 months) and durable viral suppression (HIV-1 RNA value of ≤ 200 copies/milliliter in all measurements within the past 12 months). RESULTS: Of the 1,902 PLWH receiving antiretroviral therapy, completed an interview, and had a linked MRA, 20% reported marijuana use (13% less than daily and 7% daily use) and 73% achieved durable viral suppression. In multivariable analysis, marijuana use was not significantly associated with durable viral suppression in daily [Adjusted Odds Ratio (AOR): 0.87, 95% confidence interval (CI): 0.58, 1.33] or in less than daily [AOR: 0.83, 95% CI: 0.51, 1.37] users as compared to non-users when adjusting for sociodemographic factors, time since HIV diagnosis, depressive symptoms, alcohol, cigarette and other substance use. CONCLUSION: In this sample of PLWH receiving medical care in Florida, there was no statistically significant association between marijuana use and viral suppression. However, as the limits of the confidence intervals include effects that may be considered to be clinically important, there is a need for additional evidence from other samples and settings that include more marijuana users.

RESUMO

BACKGROUND: Marijuana use is common among HIV+ individuals, but few studies have examined long-term trends in prevalence and correlates of use. METHODS: We evaluated trends (1984-2013) in the annual prevalence of current (past 6-month use) and daily (among current users) marijuana use and determined correlates of use among 2742 HIV-seropositive (HIV+) and 3172 HIV-seronegative (HIV-) men who have sex with men in the Multicenter AIDS Cohort Study (MACS). Poisson regression models were used to estimate prevalence ratios of marijuana use separately for the men who were enrolled before 2001 (early-cohort) and after 2001 (late-cohort). RESULTS: Over the 29 years of the study, the prevalence of current marijuana use declined significantly, whereas daily use among users increased among all men in the early and late-cohorts. A HIV+ status was associated with higher prevalence of marijuana use among the men in the early-cohort (adjusted prevalence ratio [aPR] = 1.53, 95% confidence interval [CI]:1.42, 1.64, p = <0.0001), but not in the men in the late-cohort (aPR = 0.90, 95% CI: 0.79, 1.03, p = 0.1424). Alcohol use and cigarette smoking were being positively associated with marijuana use. CONCLUSIONS: Although the annual prevalence of current marijuana use decreased significantly over time in the MACS, daily use among users increased significantly. Further, among the HIV+ men, our study did not show clinically significant adverse effects of marijuana use on highly active antiretroviral therapy use, CD4+ count, or HIV viral load.

RESUMO

To determine the relationships among body mass index (BMI), and HIV-associated neurocognitive impairment and the potential mediating effects of inflammatory cytokines. Among the HIV-infected individuals (N = 90) included in this study, obesity was associated with slower processing speed (ß = -.229, standard error (SE) = 2.15, p = .033), compared to participants with a normal BMI, after controlling for psychosocial and HIV clinical factors. Serum concentrations of the interleukin-16 (IL-16) cytokine were significantly associated with slowed processing speed (ß = -.235, SE = 1.62, p = .033) but did not mediate the relationship between obesity and processing speed These findings suggest that obesity may contribute to cognitive processing speed deficits in HIV-infected adults. Elevated concentrations of IL-16 are also associated with slowing, though the results suggest that obesity and IL-16 may exert independent effects.

RESUMO

Background: The relationship between cannabis and inflammation among persons with HIV (PWH) remains unclear. We examined whether the cannabis metabolite 11-nor-9-carboxy THC (THC-COOH) is associated with lower levels of plasma biomarkers of inflammation, immune activation, and microbial translocation in PWH. We hypothesized that cannabis use would be associated with lower levels of plasma inflammatory biomarkers than noncannabis use. Methods: We quantified THC-COOH in plasma, with THC-COOH levels between 5.1-69.9 µg/L and ≥70 µg/L being classified as moderate and heavy cannabis use, respectively, with noncannabis use defined as undetected THC-COOH. We measured a panel of plasma biomarkers of inflammation (interleukin [IL]-1-ß, tumor necrosis factor-alpha, IL-18, IL-6, and C-reactive protein), immune activation (CD14 and CD163), and microbial translocation (iFABP2 and lipopolysaccharide binding protein [LBP]), with all biomarkers collected on the same day. We used a cross-sectional design and linear regression models to test whether cannabis use is associated with lower biomarker levels. Results: Participants were (N=107) sexual minority men with HIV (median age=32 years, IQR=28, 38), of whom 65% were virally suppressed; 36%, 44%, and 20% were classified as nonuse, moderate, and heavy cannabis, respectively. In linear regression models adjusted for viral suppression, stimulant use, and CD4 counts, heavy cannabis use was significantly associated with lower levels of log10 LBP (ß=-0.14, 95% confidence interval: -0.24 to -0.04; false discovery rate=0.0029; partial eta squared=0.07) than noncannabis users. No precise associations were observed for other biomarkers (all p>0.05). Conclusions: Our findings suggest that cannabis use may be associated with lower plasma LBP. Further work is needed to clarify the relationship between cannabis use and biomarkers of microbial translocation in PWH.

RESUMO

Background: There has been a significant increase in methamphetamine use and methamphetamine use disorder (Meth UD) in the United States, with evolving racial and ethnic differences. Objectives: This secondary analysis explored racial and ethnic differences in baseline sociodemographic and clinical characteristics as well as treatment effects on a measure of substance use recovery, depression symptoms, and methamphetamine craving among participants in a pharmacotherapy trial for Meth UD. Methods: The ADAPT-2 trial (ClinicalTrials.gov number, NCT03078075; N=403; 69% male) was a multisite, 12-week randomized, double-blind, trial that employed a two-stage sequential parallel design to evaluate the efficacy of combination naltrexone (NTX) and oral bupropion (BUP) vs. placebo for Meth UD. Treatment effect was calculated as the weighted mean change in outcomes in the NTX-BUP minus placebo group across the two stages of treatment. Results: Of the 403 participants in the ADAPT-2 trial, the majority (65%) reported non-Hispanic White, while 14%, 11% and 10% reported Hispanic, non-Hispanic Black, and non-Hispanic other racial and ethnic categories respectively. At baseline non-Hispanic Black participants reported less severe indicators of methamphetamine use than non-Hispanic White. Treatment effects for recovery, depression symptoms and methamphetamine cravings did not significantly differ by race and ethnicity. Conclusions: Although we found racial and ethnic differences at baseline, our findings did not show racial and ethnic differences in treatment effects of NTX-BUP on recovery, depression symptoms and methamphetamine cravings. However, our findings also highlight the need to expand representation of racial and ethnic minority groups in future trials.

RESUMO

Aging gay and bisexual men may have negative self-images due to body image dissatisfaction and internalized ageism, resulting in psychological distress. Gay and bisexual men with HIV may be at greater risk for distress because of research linking HIV to accelerated aging. We examined associations between self-image and psychological distress, and potential mediating effects (resilience, fitness engagement), and whether these relationships were moderated by HIV serostatus. We tested our hypotheses with structural equation modeling using data from gay and bisexual men with HIV (n = 525, Mage = 57.6) and without HIV (n = 501, Mage = 62.2). We observed significant positive associations between self-image and distress and significant mediation effects (resilience, fitness engagement) that were moderated by HIV serostatus (resilience was only significant for men with HIV). We conclude that resilience interventions may be beneficial in alleviating distress from negative self-image among aging gay and bisexual men with HIV.

RESUMO

Objectives To determine whether self-perception of aging is an important marker of health and hypertension among older sexual minority men. Methods We evaluated associations between self-perception of aging (chronologic-subjective age discrepancy and aging satisfaction) and hypertension among 1,180 sexual minority men (51.6% with HIV/48.4% without HIV) from the Multicenter AIDS Cohort Study using a manifest Markov chain model adjusted for HIV status, age, race/ethnicity, education, smoking status, inhaled nitrite use, diabetes, dyslipidemia, kidney and liver disease. Results The overall prevalence of hypertension increased from 73.1% to 82.6% over three years of follow-up. Older age discrepancy (aOR (adjusted odds ratio): 1.13 95% CI: 0.35-3.69) and low aging satisfaction (aOR: 0.88; 95% CI: 0.31-2.52) were not associated with an increased prevalence of hypertension, regardless of HIV status. Discussion More than 80% of sexual minority men had a diagnosis of hypertension but self-perception of aging was not predictive of incident hypertension.

RESUMO

Background and Objectives: Loneliness is associated with frailty among older adults (60+), and there is evidence suggesting that this association may be bidirectional. However, there is limited evidence of this relationship over time among middle-aged and aging sexual minority men. We explored the bidirectional relationship between loneliness and frailty over 2 years among sexual minority men living with or without human immunodeficiency virus (HIV) from the Healthy Aging substudy of the Multicenter AIDS Cohort Study. Research Design and Methods: We used data from 1 118 men (561 living with HIV; 557 living without HIV) aged 40 years or older with measurement of frailty or loneliness at Times 1 (September 2016 to March 2017) and 2 (September 2018 to March 2019). Descriptive statistics were generated. We used autoregressive cross-lagged panel analysis to examine the bidirectional association between frailty and loneliness at both time points while adjusting for time-stable and time-dependent covariates at Time 1. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were generated. Results: The estimated prevalence of loneliness at both time points was 35.5%. The estimated prevalence of frailty at Times 1 and 2 were 7.8% and 12.1%, respectively. Participants reporting loneliness at Time 1 had greater odds of being frail at Time 2 (aOR = 2.14; 95% CI: 1.23-3.73). Frailty at Time 1 was not associated with loneliness at Time 2 (aOR = 1.00; 95% CI: .44-2.25). The autoregressive effects of frailty (aOR = 23.43; 95% CI: 11.94-46) and loneliness (aOR = 13.94; 95% CI: 9.42-20.61) were large. Discussion and Implications: Men who felt lonely had higher odds of being frail 2 years later while the reciprocal association was not shown. This suggests that loneliness preceded frailty and not the other way around. Early and frequent assessments of loneliness may present opportunities for interventions that minimize the risk of frailty among sexual minority men living with and without HIV.

RESUMO

PURPOSE: To determine the association between cigarette use (i.e., never-use - reference group, exclusive e-cigarette users, exclusive cigarette smoking, and dual use of both products) with cardiometabolic risk biomarkers. METHODS: Data came from two cycles (2015-2016 and 2017-2018) of the National Health and Nutrition Examination Survey. We used weighted logistic regression models to determine the association of cigarette use and reduced high-density lipoprotein cholesterol (HDL-C; <40 mg/dL, for men and <50 mg/dL for women), elevated low-density lipoprotein cholesterol (LDL-C; ≥130 mg/dL), elevated triglycerides (TG; ≥150 mg/dL), elevated fasting blood glucose (FBG; (≥100 mg/dL), and high blood pressure (HBP; Systolic ≥130 mm Hg/Diastolic ≥85 mm Hg). RESULTS: Of the 8688 adults 18+ years of age included, 2.7%, 3.2%, and 14.9% self-reported exclusive e-cigarette, dual use, and exclusive cigarette smoking respectively. After adjusting for covariates, exclusive e-cigarette use was significantly associated with increased odds of HBP (adjusted odds ratio [aOR] = 2.05, 95% confidence interval [CI] = 1.03, 4.08). Dual use was associated with increased odds of reduced HDL-C (aOR = 1.64, 95% [CI] = 1.01, 2.70). Exclusive cigarette smoking was significantly associated with reduced HDL-C (aOR=1.80, 95% [CI]=1.45, 2.23) and elevated TG (aOR = 1.59, 95% [CI] = 1.01, 2.52). CONCLUSIONS: Results are preliminary and warrant replication from larger samples with longitudinal follow-up.
