RESUMEN

BACKGROUND: Data collection and cleaning procedures to exclude bot-generated responses are used to maintain the data integrity of samples from online surveys. However, these procedures may be time-consuming and difficult to implement. Thus, we aim to evaluate the validity of a single-step geolocation algorithm for recruiting eligible gay, bisexual, and men who have sex with men in Philadelphia for an online study. METHODS: We used a 4-step approach, based on common practices for evaluating bot-generated and fraudulent responses, to assess the validity of participants' Qualtrics survey data as our referent standard. We then compared it to Qualtrics' single-step geolocation algorithm that used the MaxMind commercial database to map participants' Internet protocol address to their approximate location. We calculated the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the single-step geolocation approach relative to the 4-step approach. RESULTS: There were 826 respondents who completed the survey and 440 (53%) were eligible for enrollment based on the 4-step approach. The single-step geolocation approach yielded a sensitivity of 91% (95% CI = 88%, 93%), specificity of 79% (95% CI = 74%, 83%), PPV of 83% (95% CI = 80%, 86%), and NPV of 88% (95% CI = 85%, 91%). CONCLUSIONS: Geolocation alone provided a moderately high level of agreement with the 4-step approach for identifying geographically eligible participants in the online sample, but both approaches may be subject to additional misclassification. Researchers may want to consider multiple procedures to ensure data integrity in online samples.

RESUMEN

Objectives. To evaluate the occurrence of HIV and COVID-19 infections in Philadelphia, Pennsylvania, through July 2020 and identify ecological correlates driving racial disparities in infection incidence. Methods. For each zip code tabulation area, we created citywide comparison Z-score measures of COVID-19 cases, new cases of HIV, and the difference between the scores. Choropleth maps were used to identify areas that were similar or dissimilar in terms of disease patterning, and weighted linear regression models helped identify independent ecological predictors of these patterns. Results. Relative to COVID-19, HIV represented a greater burden in Center City Philadelphia, whereas COVID-19 was more apparent in Northeast Philadelphia. Areas with a greater proportion of Black or African American residents were overrepresented in terms of both diseases. Conclusions. Although race is a shared nominal upstream factor that conveys increased risk for both infections, an understanding of separate structural, demographic, and economic risk factors that drive the overrepresentation of COVID-19 cases in racial/ethnic communities across Philadelphia is critical. Public Health Implications. Difference-based measures are useful in identifying areas that are underrepresented or overrepresented with respect to disease occurrence and may be able to elucidate effective or ineffective mitigation strategies.

RESUMEN

BACKGROUND: In 2015, approximately 50,000 new HIV infections occurred in the United States, 2,400 of which were attributable to injection drug use. Preexposure prophylaxis (PrEP) has the potential to curb HIV acquisition; however, uptake remains low among persons who inject drugs (PWID). The purpose of the study is to describe PrEP eligibility, willingness to use PrEP, and ability to access PrEP among PWID recruited from a pilot program that paired screening and treatment of sexually transmitted infections with mobile syringe exchange program (SEP) services. METHODS: Between 2015 and 2016, 138 PWID 18 years or older were recruited from a mobile SEP in Camden, New Jersey. Participants completed a survey assessing sociodemographics and HIV risk and underwent chlamydia and gonorrhea screening. Centers for Disease Control clinical guidelines were used to calculate PrEP eligibility. Differences by sex were examined using inferential statistics. RESULTS: Most women (95.4%) and men (84.5%) were considered PrEP eligible (P < 0.04). More women than men were willing to take PrEP (88.9% vs. 71.0%; P < 0.02). Participants reported substantial barriers to PrEP including feeling embarrassed (45.0%) or anxious (51.6%) about taking PrEP, nondisclosure to partners (51.4%), limited engagement with health care providers where PrEP might be provided (43.8%), and lacking health insurance (32.9%). CONCLUSIONS: Despite reporting behavior that warrants the use of PrEP to prevent HIV and finding the concept acceptable, PWID face multiple barriers to PrEP access. Without tailored interventions to promote PrEP, uptake will likely remain suboptimal. Packaging PrEP with SEP services could provide a viable option for reaching eligible and interested PWID.

RESUMEN

BACKGROUND: Little is known about cardiovascular health disparities for lesbian, gay, or bisexual (LGB) persons and whether these disparities are mediated by mental health disorders due to sexual minority stress. We hypothesize LGB identity is associated with an increased risk of cardiovascular disease (CVD) and that major depressive disorder (MDD) and generalized anxiety disorders (GAD) may mediate this association. METHODS: The National Epidemiologic Survey on Alcohol and Related Conditions is a longitudinal, nationally-representative study of non-institutionalized U.S. adults. We cross-sectionally analyzed the second wave data (2004-2005) comparing 577 self-identified LGB persons to 33,598 heterosexuals. Multiple logistic regression modeling and mediation analysis (the product of coefficients approach) were performed. RESULTS: LGB persons had significantly higher CVD prevalence [adjusted odds ratio (AOR): 1.5, 95% CI: 1.2-1.9], and were more likely to be diagnosed with MDD (AOR: 1.9, 1.8-2.1), GAD (AOR: 2.2, 1.9-2.4), or co-occurring MDD and GAD (AOR: 2.2, 2.0-2.5). MDD, GAD, and co-occurrence of MDD and GAD significantly mediated 14.3%, 22.2%, and 33.3% of the association of LGB status with increased CVD prevalence, respectively. CONCLUSIONS: Our findings identified a 50% increased CVD prevalence among LGB persons and this increased risk was mediated in part by MDD and GAD, both being more prevalent in sexual minority adults.

RESUMEN

BACKGROUND: Men who have sex with men (MSM) continue to be overrepresented for new HIV infections compared with non-MSM. This disparity becomes even more alarming when considering racial groups. We describe the race-specific effects in HIV prevalence among MSM relative to non-MSM and explore the causes of disagreement among estimates. METHODS: We used data from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative longitudinal survey conducted in the US Bayesian learning corrected for potential misclassification of MSM status and adjusted for residual confounding, hypothesized to explain the MSM racial disparity in HIV. We articulated the structure and strength of the latent confounders that would make race-specific risk gradients equivalent. RESULTS: Compared with non-MSM, the adjusted prevalence odds ratio (POR) and 95% credible interval for black MSM having self-reported HIV infection was 5.8 (2.0, 16), while the POR for white MSM was 12 (4.2, 31). For all MSM, the POR for HIV infection was 9.3 (3.6, 23) with black men having 2.6 times the odds of prevalent infection compared with white men. CONCLUSIONS: The observed race-specific associations in MSM are likely not due to misclassification alone, but represent a constellation of factors that differ between racial groups. We recommend specific risk factors in surveys needed to further identify the behavioral characteristics that lead to the observed differences when the estimates are stratified by race.

RESUMEN

Depression is a barrier to employment among low-income caregivers receiving Temporary Assistance for Needy Families (TANF), and adverse childhood experiences (ACEs) and exposure to community violence (ECV) are often associated with depression. Using baseline data of 103 TANF caregivers of young children of the Building Wealth and Health Network Randomized Controlled Trial Pilot, this study investigated associations of two forms of employment-related resilience-self-efficacy and employment hope-with exposure to adversity/violence and depression, measured by the Center for Epidemiologic Studies Depression (CES-D) short form. Using contingency table analysis and regression analysis, we identified associations between ACEs and depression [OR = 1.70 (1.25-2.32), p = 0.0008] and having high levels of ECV with a 6.9-fold increased risk for depression when compared with those without ECV [OR = 6.86 (1.43-33.01), p = 0.02]. While self-efficacy and employment hope were significantly associated with depression, neither resilience factor impacted the association of ACE level and depression, whereas self-efficacy and employment hope modestly reduced the associations between ECV and depression, 13 and 16%, respectively. Results suggest that self-efficacy and employment hope may not have an impact on the strong associations between adversity, violence, and depression.

RESUMEN

Diagnosis of pertussis remains a challenge, and consequently research on the risk of disease might be biased because of misclassification. We quantified this misclassification and corrected for it in a case-control study of children in Philadelphia, Pennsylvania, who were 3 months to 6 years of age and diagnosed with pertussis between 2011 and 2013. Vaccine effectiveness (VE; calculated as (1 - odds ratio) × 100) was used to describe the average reduction in reported pertussis incidence resulting from persons being up to date on pertussis-antigen containing vaccines. Bayesian techniques were used to correct for purported nondifferential misclassification by reclassifying the cases per the 2014 Council of State and Territorial Epidemiologists pertussis case definition. Naïve VE was 50% (95% confidence interval: 16%, 69%). After correcting for misclassification, VE ranged from 57% (95% credible interval: 30, 73) to 82% (95% credible interval: 43, 95), depending on the amount of underreporting of pertussis that was assumed to have occurred in the study period. Meaningful misclassification was observed in terms of false negatives detected after the incorporation of infant apnea to the 2014 case definition. Although specificity was nearly perfect, sensitivity of the case definition varied from 90% to 20%, depending on the assumption about missed cases. Knowing the degree of the underreporting is essential to the accurate evaluation of VE.

RESUMEN

BACKGROUND: Families with children under age six participating in the Temporary Assistance for Needy Families Program (TANF) must participate in work-related activities for 20 h per week. However, due to financial hardship, poor health, and exposure to violence and adversity, families may experience great difficulty in reaching self-sufficiency. The purpose of this report is to describe study design and baseline findings of a trauma-informed financial empowerment and peer support intervention meant to mitigate these hardships. METHODS: We conducted a randomized controlled trial of a 28-week intervention called Building Wealth and Health Network to improve financial security and maternal and child health among caregivers participating in TANF. Participants, recruited from County Assistance offices in Philadelphia, PA, were randomized into two intervention groups (partial and full) and one control group. Participants completed questionnaires at baseline to assess career readiness, economic hardship, health and wellbeing, exposure to adversity and violence, and interaction with criminal justice systems. RESULTS: Baseline characteristics demonstrate that among 103 participants, there were no significant differences by group. Mean age of participants was 25 years, and youngest child was 30 months. The majority of participants were women (94.2 %), never married (83.5 %), unemployed (94.2 %), and without a bank account (66.0 %). Many reported economic hardship (32.0 % very low household food secure, 65.0 % housing insecure, and 31.1 % severe energy insecure), and depression (57.3 %). Exposure to adversity was prevalent, where 38.8 % reported four or more Adverse Childhood Experiences including abuse, neglect and household dysfunction. In terms of community violence, 64.7 % saw a seriously wounded person after an incident of violence, and 27.2 % had seen someone killed. Finally, 14.6 % spent time in an adult correctional institution, and 48.5 % of the fathers of the youngest child spent time in prison. CONCLUSIONS: Baseline findings demonstrate that caregivers participating in TANF have suffered significant childhood adversity, adult violence exposure, and poverty-related stressors that can limit workforce success. High prevalence of housing and food insecurity, exposure to adversity, violence and criminal justice systems demands comprehensive programming to support families. Trauma-informed approaches to career readiness such as the Building Wealth and Health Network offer opportunities for potential success in the workforce. TRIAL REGISTRATION: This study is retrospectively registered with ClinicalTrials.gov. The Identifier is: NCT02577705 The Registration date is October 13, 2015.

RESUMEN

BACKGROUND: Inferring sexual behavior of a stigmatized minority through self-reported sexual identity is subject to misclassification and can lead to biased results. We quantify the degree of this misclassification and perform a Bayesian correction of the risk of HIV infection in relation to self-reported sexual behavior. METHODS: Sensitivity and specificity of self-reported men who have sex with men in ascertaining sexual behavior was derived from validation data, as was the informative prior on the association of same-sex behavior with self-reported HIV infection. Using these priors, we performed two separate Bayesian analyses of National Epidemiologic Survey on Alcohol and Related Conditions data for the odds of self-reported HIV positivity, adjusting for differential misclassification of self-reported same-sex behavior indicated by either partner gender or sexual identity. RESULTS: We found differential exposure misclassification with specificity exceeding sensitivity, and higher misclassification rates based on sexual identity compared with partner gender. Sexual identity and partner gender displayed different associations with HIV infection in the raw data but these became virtually identical when adjusted for estimates of misclassification of sexual behavior by these two indicators. The estimate of prevalence of same-sex behavior associated with an elevated risk of HIV infection decreased after adjustment for misclassification. CONCLUSIONS: Studies of risk due to same-sex behavior are likely biased when they rely on self-identification for ascertainment of risk factors, especially when self-reported identity is used. The implications of our findings on risk modeling cannot be assumed to be trivial due to substantial shifts in distributions of risk and prevalence of exposure.

RESUMEN

Clostridium difficile-associated disease (CDAD) constitutes a large majority of nosocomial diarrhea cases in industrialized nations and is mediated by the effects of two secreted toxins, toxin A (TcdA) and toxin B (TcdB). Patients who develop strong antitoxin antibody responses can clear C. difficile infection and remain disease free. Key toxin-neutralizing epitopes have been found within the carboxy-terminal receptor binding domains (RBDs) of TcdA and TcdB, which has generated interest in developing the RBD as a viable vaccine target. While numerous platforms have been studied, very little data describes the potential of DNA vaccination against CDAD. Therefore, we created highly optimized plasmids encoding the RBDs from TcdA and TcdB in which any putative N-linked glycosylation sites were altered. Mice and nonhuman primates were immunized intramuscularly, followed by in vivo electroporation, and in these animal models, vaccination induced significant levels of both anti-RBD antibodies (blood and stool) and RBD-specific antibody-secreting cells. Further characterization revealed that sera from immunized mice and nonhuman primates could detect RBD protein from transfected cells, as well as neutralize purified toxins in an in vitro cytotoxicity assay. Mice that were immunized with plasmids or given nonhuman-primate sera were protected from a lethal challenge with purified TcdA and/or TcdB. Moreover, immunized mice were significantly protected when challenged with C. difficile spores from homologous (VPI 10463) and heterologous, epidemic (UK1) strains. These data demonstrate the robust immunogenicity and efficacy of a TcdA/B RBD-based DNA vaccine in preclinical models of acute toxin-associated and intragastric, spore-induced colonic disease.

RESUMEN

More than three decades after the first cases of HIV were recognized in the United States and worldwide, Africa remains a remarkable example of both public health successes and remaining challenges. Although many African countries initially lacked the resources and sociopolitical will to advance HIV treatment and prevention strategies, world governments, a committed scientific community, and activists have made tremendous advances. We present a public health perspective on the history of the HIV epidemic in Africa, combining summaries of the epidemiology of HIV infection rates and risk factors for horizontal and vertical HIV transmission, along with a historic perspective on programmatic and funding initiatives that have strongly reduced levels of HIV infection across the continent. In our preparation of this review two clear themes emerged: that (1) the HIV epidemic in Africa remains geographically and culturally heterogeneous, so that treatment and prevention strategies need to be thoughtfully tailored for maximal effectiveness; and (2) a lack of openness to recognize and discuss infection disparities in high risk groups, disseminate prevention information, and enact policies to partner with these highly stigmatized risk groups. This is especially true of female sex workers, people who inject drugs, and men who have sex with men, communities that are often not recognized or typically undercounted when HIV testing and prevention policies are developed by many African governments. Without changes to recognize and de-stigmatize these high-risk groups, a lack of sociopolitical will to alter public health perspectives will likely hinder advances to further curb the HIV epidemic.

RESUMEN

Doxycycline post-exposure prophylaxis (PEP) holds the potential to mitigate increasing rates of syphilis among sexual minority men (SMM) in the US yet has received limited attention. Since evaluation of this intervention in actual populations is not currently feasible, we used agent-based models (ABM) to assess the population-level impact of this strategy. We adapted ABM of HIV and HPV transmission, representing a population of 10,230 SMM in Philadelphia, Pennsylvania, US. Parameter inputs were derived from the literature, and ABM outputs during the pre-intervention period were calibrated to local surveillance data. Intervention scenarios varied doxycycline uptake by 20, 40, 60, 80 and 100%, while assuming continued condom use and syphilis screening and treatment. Under each intervention scenario, we incorporated treatment adherence at the following levels: 0, 20, 40, 60, 80 and 100%. Long-term population impact of prophylactic doxycycline was measured using the cumulative incidence over the 10-year period and the percentage of infections prevented attributable to doxycycline at year 10. An uptake scenario of 20% with an adherence level of 80% would reduce the cumulative incidence of infections by 10% over the next decade, translating to 57 fewer cases per 1000 SMM. At year 10, under the same uptake and adherence level, 22% of infections would be prevented due to doxycycline PEP in the instances where condoms were not used or failed. Findings suggest that doxycycline PEP will have a modest impact on syphilis incidence when assuming a reasonable level of uptake and adherence. Doxycycline PEP may be most appropriate as a secondary prevention measure to condoms and enhanced syphilis screening for reducing infections among SMM.

RESUMEN

Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was recently approved for HIV prevention as an alternative to daily oral PrEP. We explored preferences and attitudes toward LAI-PrEP among Black, Hispanic/Latino, and White gay, bisexual, and other men who have sex with men (GBM) using focus groups (n = 13) and in-depth interviews (n = 17). Participants expressed differing levels of interest in LAI-PrEP. While important benefits of LAI-PrEP included convenience, provider-facilitated PrEP discussion, and expansion of PrEP options, participants raised concerns about treatment efficacy and side effects, discomfort with needles/injections, cost, and frequency of clinic visits. Our findings highlight ongoing challenges with accessing HIV-prevention tools and provide guidance for developing strategies to enhance LAI-PrEP uptake among GBM.

RESUMEN

BACKGROUND: Chorioamnionitis is a risk factor for fetal and neonatal outcomes. Therefore, predicting histological chorioamnionitis (HCA) and neonatal outcomes using clinical parameters could be helpful in management and preventing morbidities. OBJECTIVE: To determine if parameters of clinical chorioamnionitis (CCA) would be associated with HCA and neonatal outcomes. STUDY DESIGN: In this cohort study using a retrospective design, we analyzed the performance of signs of CCA in predicting HCA, and neonatal outcomes. Data were extracted from the electronic health record for all neonates with documented CCA delivered at our institution from 2011 to 2016. We compared our findings based on the old ACOG definition of CCA and the new definition released in 2017 - maternal fever plus any of fetal tachycardia, maternal leukocytosis, and purulent vaginal discharge. Maternal tachycardia and uterine tenderness were removed from the new criteria. Neonatal laboratory samples on admission, 12 h and 24 h were used to define the three time points of neonatal suspected sepsis. RESULTS: There were 530 mothers-infant dyads with chorioamnionitis. Seventy-three were preterm, and 457 were term. Eighty-eight percent of the preterm mothers had CCA, and HCA was present in 62.5% of 72 preterm placentas. Preterm infants with placental HCA significantly had lower birth weight, gestational age, placental weight, and more infants with lower 5-minute Apgar scores, compared to those with no HCA. In preterm infants, maternal urinary tract infection was significantly associated with decreased odds for HCA (OR 0.22, CI 0.10 - 0.71). More preterm babies with suspected sepsis criteria at the 3 time points had HCA (all p ≤ .01). In the term cohort, 95.4% and 65.6% had CCA and HCA, respectively. In term infants (n = 457), maternal leukocytosis (p = .002) and prolonged rupture of membranes (PROM; p = 002) were associated with HCA. Suspected sepsis was associated with PROM (p = .04), HCA (p = .0001), and maternal leukocytosis (p ≤ .05) in at least 1 of the 3 time points. CONCLUSION: Though maternal leukocytosis was significantly associated with the presence of HCA in the term cohort, there were no CCA criteria that accurately predicted presence of HCA in either the preterm or the term infants.

RESUMEN

Little is known about the prevalence of intimate partner violence (IPV) among men who have sex with men (MSM) or about childhood adversity as a predictor of IPV among MSM. Studies have documented high rates of childhood sexual abuse among MSM. To evaluate associations of early-life sexual and physical abuse with IPV among African American heterosexual men or MSM, prevalence of early-life (≤ 21 years) sexual and physical abuse was measured among 703 nonmonogamous African American men. Men were classified as (1) MSM who disclosed male sex partners; (2) MSM who initially denied male sex partners but subsequently reported oral-genital and anal-genital behaviors with men; (3) non-MSM. MSM who initially disclosed male sex partners reported significantly (P < 0.0001) higher rates of early physical abuse (36%) and lifetime abuse (49%) compared with non-MSM (15 and 22%), respectively. These MSM reported significantly higher rates of sexual abuse by age 11, age 21, and over a lifetime compared with non-MSM (P < 0.0001). Being an MSM who initially disclosed male sex partners (OR: 2.1; 95% CI: 1.2, 3.6) and early-life sexual abuse (OR: 2.8; 95% CI: 1.8, 4.3) was associated with IPV victimization in current relationships. Similarly, being an MSM with early-life physical and sexual abuse was associated (0.0004 ≤ P ≤ 0.07) with IPV perpetration. Early-life physical and sexual abuse was higher among MSM who disclosed male sex partners compared with heterosexual men; however, all MSM who experienced early-life abuse were more likely to be IPV victims or perpetrators.

RESUMEN

OBJECTIVE: To investigate associations between healthcare-associated Clostridioides difficile infection and patient demographics at an urban safety-net hospital and compare findings with national surveillance statistics. METHODS: Study participants were selected using a case-control design using medical records collected between August 2014 and May 2018 at Hahnemann University Hospital in Philadelphia. Controls were frequency matched to cases by age and length of stay. Final sample included 170 cases and 324 controls. Neighborhood-level factors were measured using American Community Survey data. Multilevel models were used to examine infection by census tract, deprivation index, race/ethnicity, insurance type, referral location, antibiotic use, and proton-pump inhibitor use. RESULTS: Patients on Medicare compared to private insurance had 2.04 times (95% CI, 1.31-3.20) the odds of infection after adjusting for all covariables. Prior antibiotic use (2.70; 95% CI, 1.64-4.46) was also associated with infection, but race or ethnicity and referral location were not. A smaller proportion of hospital cases occurred among white patients (25% vs 44%) and patients over the age of 65 (39% vs 56%) than expected based on national surveillance statistics. CONCLUSIONS: Medicare and antibiotics were associated with Clostridioides difficile infection, but evidence did not indicate association with race or ethnicity. This finding diverges from national data in that infection is higher among white people compared to nonwhite people. Furthermore, a greater proportion of hospital cases were aged <65 years than expected based on national data. National surveillance statistics on CDI may not be transportable to safety-net hospitals, which often disproportionately serve low-income, nonwhite patients.

RESUMEN

Few behavioral interventions have been conducted to reduce high-risk sexual behavior among HIV-positive Men who have Sex with Men (HIV+ MSM). Hence, we lack well-proven interventions for this population. Positive Connections is a randomized controlled trial (n = 675 HIV+ MSM) comparing the effects of two sexual health seminars--for HIV+ MSM and all MSM--with a contrast prevention video arm. Baseline, 6-, 12- and 18-month follow-up surveys assessed psychosexual variables and frequency of serodiscordant unprotected anal intercourse (SDUAI). At post-test, intentions to avoid transmission were significantly higher in the sexual health arms. However, SDUAI frequency decreased equally across arms. HIV+ MSM engaging in SDUAI at baseline were more likely to leave the study. Tailoring interventions to HIV+ MSM did not increase their effectiveness in this study. A sexual health approach appeared as effective as an untailored video-based HIV prevention intervention in reducing SDUAI among HIV+ MSM.

RESUMEN

OBJECTIVES: We assessed rates of childhood sexual abuse and its demographic and mental health correlates among HIV-positive men who reported unsafe anal intercourse with other men in the past year. METHODS: We conducted a cross-sectional analysis of baseline data from 593 HIV-positive men who have sex with men enrolled in the Positive Connections intervention. RESULTS: Childhood sexual abuse was reported by 47% of participants; 32% reported frequency as often or sometimes. Men reporting abuse were more likely to be Latino (odds ratio [OR] = 2.6; 95% confidence interval [CI] = 1.6, 4.2; P < .001) or African American (OR = 1.8; 95% CI = 1.2, 2.7; P = .005) than White. Among those who were abused, more frequent abuse was associated with more sexual contacts (for each, rate ratio [RR] = 1.3; P < .001) and unsafe anal intercourse (often, RR = 1.5; sometimes, RR = 2.0; P < .001) compared with men who were not abused. CONCLUSIONS: History of childhood sexual abuse is highly prevalent among HIV-positive men who engage in risky sexual behavior with other men and appears to be more common among men of color. Our findings suggest that abuse is associated with a significantly increased risk of sexually transmitted infections.

RESUMEN

The EXPLORE study evaluated a behavioral intervention to prevent HIV infection among MSM. We examined depressive symptoms, utilization of mental health care, substance use and HIV risk taking behaviors in YMSM aged 16-25 years compared with their older counterparts. YMSM were more likely to report depressive symptoms (OR = 1.55) and less likely to report use of counseling (OR = 0.39) or medication (OR = 0.20) for psychiatric conditions. YMSM were more likely to report heavy alcohol and drug use. YMSM more often reported engaging in unprotected insertive (OR = 1.60) and receptive (OR = 2.07) anal intercourse with presumed HIV-uninfected partners, and unprotected receptive (OR = 1.72) anal intercourse with partners of unknown-HIV status. These findings suggest the need for more appropriate and accessible mental health care and substance use services for YMSM. Additionally, HIV prevention work with this population should provide comprehensive education about HIV testing and risk reduction counseling that focuses on communication about serostatus and safety in sexual situations.

RESUMEN

Potential items to be included in an HIV Treatment Optimism scale were reviewed by 17 HIV-positive gay and bisexual men (GBM), resulting in a 21-item test instrument. After pilot testing, data were collected from a multi-city sample of high-risk HIV-positive GBM (n=346), who were currently on treatment and were recruited to attend a two-day sexual health seminar. The scale items were analyzed utilizing Principal Components Analysis and reliability testing. The factor analysis resulted in the development of three separate scales. The Susceptibility scale contained 10 items associated with a belief that HIV is less transmissible while on HIV treatment. The Condom Motivation scale contained five items addressing a decreased motivation to use condoms while on treatment and the Severity scale contained four items associated with a decreased sense of the severity of an HIV diagnosis. Reliability coefficients (alpha) and mean inter-item correlations (M) for the three scales were acceptable (Susceptibility, alpha = 0.86, M=0.39; Condom Motivation, alpha = 0.84, M = 0.50; Severity, alpha = 0.71, M=0.37). Combined as one scale,the reliability coefficient was respectable (alpha = 0.76), but the mean inter-item correlation was 0.14. Based on this analysis, use of a single measure was not supported and three separate scales were developed. The scales were equivalent across racial groups except White men were more like to report a decreased motivation to use condoms compared to Black or Latino men. Three separate scales addressing beliefs about the transmissibility of HIV while on treatment (Susceptibility), the quality of life while on HIV treatment (Severity) and the motivation to use condoms consistently while on treatment (Condom Motivation) may be better markers for assessing optimistic beliefs about HIV treatment among HIV-positive GBM.
