Diagnostic capabilities of self-reported psychoactive substance use among patients admitted to psychiatric consultations in Benin, West Africa. BMC Psychiatry 2022; 22:752. [PMID: 36451144 PMCID: PMC9714013 DOI: 10.1186/s12888-022-04394-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 11/15/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND There is a high prevalence of psychoactive substance use among patients with mental health disorders. The optimal treatment of patients with mental health disorders requires an awareness of their history pertaining substance use. Several methods are used to assess the use of substance. Each of them embodies its limitations. This study aimed at assessing the diagnostic capability of a self-report psychoactive substance use among patients at the National Psychiatric University Hospital of Cotonou, Benin. METHODS A cross-sectional survey was conducted from August 1, 2021 to November 24, 2021. A total of 157 consenting patients admitted to psychiatric consultations were successively enrolled in the ongoing study. They were screened for the use of psychoactive substance with Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), followed by urine test using the NarcoCheck® kit for qualitative detection of substances or its metabolites. To assess the diagnostic capability, the participants' self-responses were compared with their urine test results. The sensitivity, specificity, positive and negative predictive values, and kappa coefficient were also calculated. RESULTS The frequency of lifetime psychoactive substance use according to self-report was 81.5% (95% CI: 0.746-0.873), while over the past three months (recent use) was 52.2% (95% CI: 0.441-0.603) and 58.6% based on the urine test. Alcohol, tobacco and cannabis were the most prevalent psychoactive substance used. The overall concordance between self-reported psychoactive substance use and the urine test (gold standard) was moderate (sensitivity = 66%; kappa = 0.46). Self-report cocaine use compared with urine test showed the highest concordance (sensitivity = 100%; kappa = 79%), followed by tobacco (sensitivity = 58%, kappa = 41%). On an average 70% of urine test results were consistent with self-report (VPP). Participants' were more accurate when they were reporting no psychoactive substance use as suggested by the high negative predictive value (NPV). CONCLUSION Diagnostic capability of self-reporting of psychoactive substance use among patients admitted to psychiatric consultations was moderate. Therefore self-reporting may not estimate the exact prevalence of psychoactive substance use. Optimal identification of psychoactive substances use in psychiatric patients requires both history and urine testing. The integration of these two approaches is an excellent method to find out the level, frequency and nature of drug used.

Abstract
Objective: Scant research exists on the validity of self-reported marijuana use using biological assays among adolescents involved in the juvenile justice system. This exploratory study examined gender (sex) differences in underreporting of marijuana use and the impact of age, race/ethnicity, living situation, depression, family problems, sexual risk behaviors, previous drug treatment, and juvenile justice placement. Methods: Self-reports of past year marijuana use were validated with urinalysis, and those testing positive for marijuana use were selected for study. The sample was 256 females and 885 males, aged 12 to 18, entering an urban juvenile assessment center in a southeastern U.S. state between 2017 and 2019. Results: Results indicated significant differences in marijuana underreporting (tested positive but self-reported no use), with 37% of females and 55% of males underreporting use. For males, Hispanic ethnicity, African American race, sexually transmitted infection (STI), and secure detention placement increased the odds of underreporting, while having an incarcerate parent and previous drug treatment decreased the odds. For females, number of sexual partners decreased the odds of underreporting of marijuana use. Conclusion: These findings imply use of collateral information, such as urine tests, as a recommendation for juvenile justice intake to corroborate self-reports and guide risk assessment.

Abstract
BACKGROUND The aim of this study was to investigate the association of denture stomatitis prevalence with cigarette, hookah and opium consumption and also dose-response relationship between the cigarette smoking duration and odds of denture stomatitis in population of Rafsanjan cohort center. METHODS This cross-sectional study based on data of Rafsanjan Cohort Study (RCS) with 10,000 participants. After applying inclusion and exclusion criteria, 1619 participants were included in the analysis. Data were collected by oral examination and completion of pre-designed questionnaires to assess denture hygiene, smoking behavior, opium use and some other exposure variables. Multivariable logistic regression models were fitted to investigate possible association of cigarette, hookah and opium consumption and denture stomatitis. RESULTS Prevalence of denture stomatitis among all 1619 denture wearers was 21.6%. Cigarette smoking was associated with a higher odds of denture stomatitis, with the adjusted odds ratio (95% CI) of 2.29 (1.53-3.41). Also, dose-response increases were observed with the highest odds ratio in the 4th quartile for denture stomatitis (p-value < 0.001). Opium consumption was associated with a decreased odds of denture stomatitis (adjusted OR; 0.81, 95% CI 0.58-1.13) which was not statistically significant. Also interaction between opium consumption and cigarette smoking was not associated with higher odds of denture stomatitis (adjusted OR: 1.65, 95% CI 0.85-3.22). CONCLUSIONS Based on the findings of the present study, while cigarette smoking had a dose-response relationship with the increased odds of denture stomatitis; this association was not found with opium consumption.

Drug Alcohol Depend 2019; 200:161-167. [PMID: 31146203 PMCID: PMC6588496 DOI: 10.1016/j.drugalcdep.2019.04.008] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2019] [Revised: 04/10/2019] [Accepted: 04/11/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND Biological testing can be used to validate or detect underreported drug use. Since hair testing is increasingly used in survey research, we examined how the utility of hair testing compares to a more common method-urine testing. METHODS 532 adults (ages 18-29) reporting past-month heroin use and/or nonmedical prescription opioid use were surveyed about past-month use of various drugs. Participants were urine-tested and the majority (79.3%) provided a hair sample for analysis. We examined the utility of urine vs. hair-testing in detecting past-month use of various drugs. RESULTS Compared to hair testing, urine testing was able to confirm higher proportions of self-reported use of heroin/opioids (85.5% vs. 80.9%), marijuana (73.9% vs. 22.9%), benzodiazepines (51.3% vs. 15.1%), and methadone (77.0% vs. 48.7%), while hair testing was more likely to detect reported cocaine use (66.3% vs. 48.0%) (Ps<.01). Compared to hair testing, urine testing was more likely to detect unreported use of marijuana (11.3% vs. 0.9%), and benzodiazepines (14.4% vs. 5.4%), and hair testing was more likely to detect unreported use of cocaine (27.0% vs. 5.8%) and oxycodone (19.7% vs. 1.4%) (Ps<.001). When added to urine testing, hair testing increased detection of reported and non-reported use of cocaine and oxycodone ranging from 14 to 22%. CONCLUSIONS While hair testing is efficacious in detecting drug use in wide window periods (e.g., past-year use), it is less efficacious than urine testing when testing for past-month use of select drugs among opiate/opioid users. However, hair testing is particularly efficacious in detecting unreported use of cocaine and/or oxycodone.

Abstract
Remedial programs for impaired driving offenders have proved valuable in reducing subsequent alcohol and other drug use and preventing recidivism in this population. Many of these programs are based on a severity-based assignment scheme, where individuals assessed to have greater problems or be at higher risk are assigned to longer, more intensive interventions. Recent research, using regression discontinuity analyses, provided support for severity-based assignment schemes in demonstrating that those with higher problem or risk levels assigned to longer and more intensive programming showed a significant reduction in drinking days over a follow-up interval, attributable to program assignment. Regression discontinuity analyses can also be used to assess moderators of this assignment benefit. We report an assessment of the impact of eight potential moderators of assignment benefit, derived from a factor analysis of the Research on Addictions Self-Inventory screening instrument. Five of the eight factors were found to moderate the assignment benefit: Negative Affect, Sensation Seeking, High Risk Lifestyle, Alcohol Problems, and Family History. The significance of these results for developing more effective program assignment procedures is discussed.

Abstract
BACKGROUND Antisocial personality disorder often co-exists with drug and alcohol use disorders. METHODS This trial examined the effectiveness of offering psycho-education for antisocial personality disorder in community substance use disorder treatment centers in Denmark. A total of 176 patients were randomly allocated to treatment as usual (TAU, n = 80) or TAU plus a psycho-educative program, Impulsive Lifestyle Counselling (ILC, n = 96) delivered by site clinicians (n = 39). Using follow-up interviews 3 and 9 months after randomization, we examined changes in drug and alcohol use (Addiction Severity Index Composite Scores), percent days abstinent (PDA) within last month, and aggression as measured with the Buss-Perry Aggression Questionnaire-Short Form and the Self-Report of Aggression and Social Behavior Measure. RESULTS Overall engagement in psychological interventions was modest: 71 (76 %) of participants randomized to psycho-education attended at least one counselling session, and 21 (23 %) attended all six sessions. The Median number of sessions was 2. All patients reduced drug and alcohol problems at 9 months with small within-group effect sizes. Intention-to-treat analyses indicated significant differences between ILC and TAU in mean drugs composite score (p = .018) and in PDA (p = .041) at 3 months. Aggression declined in both groups, but no differences between ILC and TAU were observed in terms of alcohol problems or aggression at any follow-up. CONCLUSIONS Moderate short-term improvements in substance use were associated with randomization to Impulsive Lifestyle Counselling. The findings support the usefulness of providing psycho-education to outpatients with antisocial personality disorder. TRIAL REGISTRATION ISRCTN registry, ISRCTN67266318 , 17/7/2012.

Abstract
OBJECTIVE Women who sell sex and use drugs have dual risks for HIV infection. Despite increasing reports of drug use among female sex workers (FSW) in Vietnam, FSW HIV interventions remain focused mainly on sexual risk reduction. We assessed the impact of drug use and inconsistent condom use on HIV infection among FSW in Vietnam, which few studies have quantified. METHODS We surveyed 5298 women aged ≥18 years who had sold sex in the past month from ten geographically dispersed provinces. We performed multivariate logistic regression on data from provinces with high (≥10%) or low (<10%) HIV prevalence among FSW. RESULTS Compared to FSW who never used illicit drugs, the odds of HIV infection among FSW who had ever injected drugs and those who reported non-injection drug use were 3.44 (CI 2.32-5.09) and 1.76 (CI 1.14-2.71), respectively, in high-prevalence provinces. FSW who always used condoms with clients had lower odds of HIV infection than those who did not (AOR=0.71; CI 0.52-0.98). In low-prevalence provinces lifetime injection drug use (AOR 22.05, CI 12.00-40.49), but not non-injecting drug use or inconsistent condom use, was significantly associated with HIV infection. CONCLUSIONS Because injection drug use and inconsistent condom use were key risk factors for HIV infection in high-prevalence provinces, drug injection risk reduction should be as much a focus of HIV prevention as sexual risk reduction. Where HIV prevalence remains low in FSW, a more general emphasis on harm reduction for all drug users will benefit FSW.

Abstract
BACKGROUND Cannabis use and misuse have become a public health problem. There is a need for reliable screening and assessment tools to identify harmful cannabis use at an early stage. We conducted a systematic review of published instruments used to screen and assess cannabis use disorders. METHOD We included papers published until January 2013 from seven different databases, following the PRISMA guidelines and a predetermined set of criteria for article selection. Only tools including a quantification of cannabis use and/or a measurement of the severity of dependence were considered. RESULTS We identified 34 studies, of which 25 included instruments that met our inclusion criteria: 10 scales to assess cannabis use disorders, seven structured interviews, and eight tools to quantify cannabis use. Both cannabis and substance use scales showed good reliability and were validated in specific populations. Structured interviews were also reliable and showed good validity parameters. Common limitations were inadequate time-frames for screening, lack of brevity, undemonstrated validity for some populations (e.g., psychiatric patients, female gender, adolescents), and lack of relevant information that would enable routine use (e.g., risky use, regular users). Instruments to quantify consumption did not measure grams of the psychoactive compounds, which hampered comparability among different countries or regions where tetrahydrocannabinol concentrations may differ. CONCLUSIONS Current instruments available for assessing cannabis use disorders need to be further improved. A standard cannabis unit should be studied and existing instruments should be adapted to this standard unit in order to improve cannabis use assessment.

Abstract
Background There have been inconsistent findings on the association between current drug use and HIV disease progression and virologic suppression. Drug use was often measured using self-report of historical use. Objective measurement of current drug use is preferred. Methods In this cross-sectional study, we assessed drug use through Computer-Assisted Self Interviews (CASI) and point-of-care urine drug screen (UDS) among 225 HIV-infected patients, and evaluated the association between current drug use and virologic suppression. Results About half (54%) of participants had a positive UDS, with a lower self-reported rate by CASI (42%) (Kappa score = 0.59). By UDS, 36.0% were positive for marijuana, 25.8% for cocaine, 7.6% for opiates, and 2.2% for methamphetamine or amphetamine. Factors associated with virologic suppression (plasma HIV RNA <50 copies/mL) were Caucasian race (P = 0.03), higher CD4 count (P < 0.01), current use of antiretroviral therapy (ART) (P < 0.01), and a negative UDS (P < 0.01). Among 178 current ART users, a positive UDS remained significantly associated with lower likelihood of virologic suppression (P = 0.04). Conclusions UDS had good agreement with CASI in detecting frequently used drugs such as marijuana and cocaine. UDS at routine clinic visits may provide “real-time” prognostic information to optimize management.

BACKGROUND Men who have sex with men (MSM), particularly young black MSM, are disproportionately affected in the United States' HIV epidemic. Drug use may contribute to these disparities, yet previous studies have failed to provide evidence of elevated use among black MSM, relying exclusively on self-reported usage. This study uses biological assays to validate self-reports of drug use and explore the potential for misclassification to distort findings on racial patterns of use in this population. METHODS From an Atlanta-based cohort study of 454 black and 349 white MSM from 2010 to 2012, participants' self-reported drug use was compared to urine drug screening findings. The sensitivity of self-report was calculated as the proportion reporting recent usage among those who screened positive. Multivariable regression models were constructed to examine racial patterns in self-report, urine-detection, and self-report sensitivity of marijuana and cocaine usage, adjusted for socio-demographic factors. RESULTS In analyses that adjusted for age, education, income, sexual orientation, and history of arrest, black MSM were less likely to report recent use of marijuana (P<0.001) and cocaine (P=0.02), but equally likely to screen positive for either drug. This discrepancy between self-reported and urine-detected drug use was explained by significantly lower sensitivity of self-report for black participants (P<0.001 for marijuana, P<0.05 for cocaine). CONCLUSIONS The contribution of individual drug-related risk behaviors to the HIV disparities between black and white MSM should be revisited with methods that validate self-reports of illegal drug use.

Abstract
The objective of this study was to compare sociodemographic, behavioral and clinical characteristics associated with HIV among Men who have sex with Men (MSM) and men who have sex with women (MSW) in Puerto Rico. Data from a population-based cross-sectional study in PR (2005-2008) was analyzed. Descriptive statistics were used to describe the study sample and bivariate analyses were performed to identify differences of sociodemographic, behavioral and clinical characteristics between MSM and MSW. Exact logistic regression models adjusting for age were constructed for each risk behavior associated to MSM in bivariate analysis. Of the 674 men interviewed, 6.1% (n=41) reported ever having sex with men. Age-adjusted logistic regression models indicated that MSM were significantly more likely than MSW to have first sexual intercourse before the age of 15 (POR=2.6; 95%CI= 1.3, 5.3) and have at least 10 lifetime sex partners (POR=2.8; 95%CI= 1.4,5.9). Also, MSM were significantly more likely to report lifetime use of marihuana (POR=2.7; 95%CI= 1.3,5.8), cocaine (POR=2.5; 95%CI= 1.2,5.0), amphetamines (POR=3.8; 95%CI= 1.4,9.2) and sedatives or tranquilizers (POR=3.3; 95%CI= 1.4,7.2). Also, MSM were 13 times more likely to be HIV seropositive as compared to MSW (POR=13.3; 95%CI=1.7,102.0). In this population-based sample of men living in Puerto Rico, self-reported same-sex behavior is strongly associated with HIV, and other behavioral factors associated with HIV. Future targeted research is still necessary for the development of intervention programs among MSM in Puerto Rico.

Abstract
Brief interventions effectively reduce alcohol problems; however, it is controversial whether longer interventions result in greater improvement. This study aims to determine whether an increase in treatment for people with more severe problems resulted in better outcome. We employed regression-discontinuity analyses to determine if drinking driver clients (n = 22,277) in Ontario benefited when they were assigned to a longer treatment program (8-hour versus 16-hour) based on assessed addiction severity criteria. Assignment to the longer16-hour program was based on two addiction severity measures derived from the Research Institute on Addictions Self-inventory (RIASI) (meeting criteria for assignment based on either the total RIASI score or the score on the recidivism subscale). The main outcome measure was self-reported number of days of alcohol use during the 90 days preceding the six month follow-up interview. We found significant reductions of one or two self-reported drinking days at the point of assignment, depending on the severity criterion used. These data suggest that more intensive treatment for alcohol problems may improve results for individuals with more severe problems.

Abstract
During the last decade, the veterinary anesthetics have gained popularity as recreational drugs. The aim of this study was to document the use of "anestecia de caballo" (xylazine) and its consequences among drug users in Puerto Rico. The study combined a cross-sectional survey with 89 drug users and two focus groups conducted in Mayagüez with frontline drug treatment providers. Drug users were recruited from communities of the San Juan metropolitan area using a variety of ethnographic and outreach strategies. A short questionnaire developed for the study collected information on sociodemographics, xylazine use, and its consequences. The two focus groups were conducted to discuss the details related to xylazine use, its consequences, and utilization awareness. The sample comprised 63 males (70.8%) and 26 females with a mean age of 37.2 years. The mean number of years of drug use was 14.3, with a mean frequency of drug use of 5.9 times daily. More than 65% reported speedball as the principal drug of use. The prevalence of xylazine use was 80.7%. More than 42% of the sample used xylazine in a mixture with speedball. The main route of administration of xylazine was injection but 14% reported the use of xylazine by inhalation. More than 35% of the sample reported skin lesions and 21.1% reported at least one overdose episode. Multiple logistic regression analysis revealed that males (OR = 3.47, CI = 1.10-12.00) and those who reported speedball as their main drug of use (OR = 9.34, CI = 2.51-34.70) were significantly more likely to be xylazine users. Focus groups revealed that drug users claimed to recognize the presence of xylaxine in a mixture of speedball based on its effects, taste, the color of the drug (dark brown), and its odor. In conclusion, the use of xylazine among drug users in Puerto Rico seems to be an emerging trend with potentially serious health consequences.

Reports of past alcohol and drug use following participation in a motivation enhancing intervention: implications for clinical assessment and program evaluation.

Abstract
BACKGROUND There is significant interest in the value of motivational approaches that enhance participant readiness to change, but less is known about clients' self-reports of problematic behavior when participating in such interventions. METHODS We examined whether participants in a motivationally-based intervention for DUI offenders changed their reports of substance use at postintervention (when reporting on the same 30 days that they reported on at preintervention). Specifically, Study 1 (N = 8,387) tested whether participants in PRIME For Life (PFL) changed their reports about baseline substance levels when asked at postintervention versus at preintervention. Study 2 (N = 192) compared changes in self-reported baseline drinking between PFL and intervention as usual (IAU) participants. RESULTS Many participants in Study 1 did not change their reports about how much they used substances during the 30-day period before baseline. Among those who did, the most common change was an increase in reported amounts of baseline drug use, and typical and peak alcohol use. This sample also showed changes in reports of their baseline pattern of high-risk-use (consistent versus occasional). At postintervention, participants who were younger, single, or endorsing more indicators of alcohol dependence were more likely to later report greater frequency of baseline drug use, and greater peak and typical number of baseline drinks. Gender, education, and race were also associated with reporting inconsistency on some behaviors. In Study 2, PFL participants showed greater increases in reports of peak alcohol use compared to IAU, but both conditions showed similar increases for drugs and typical alcohol use. CONCLUSIONS In both research and clinical settings, a segment of participants may initially report less substance use than they do when asked later about the same baseline period. These preliminary findings suggest clinicians and researchers may find postintervention evaluations yield reports of greater baseline alcohol or drug use for some people. For some behaviors, this may occur more often in interventions that target client motivation. Future research should attempt to identify which reports - preintervention vs. postintervention - better reflect actual baseline substance use.

Abstract
Although primary prevention of HAV and HBV can be achieved through vaccination, the burden of HCV can only be reduced through behavioral interventions to reduce its risk factors. This study evaluated knowledge regarding transmission, clinical manifestations and prevention of viral hepatitis in Puerto Rico. We assessed the level of knowledge about HAV (six questions), HBV (12 questions) and HCV (eight questions) among non-institutionalized Puerto Rican adults aged 21-64 years. Demographic characteristics and self-reported knowledge of these infections were determined through a face-to-face interview. A mean knowledge score was computed by summing correct responses to each scale. Mean knowledge scores according to demographics were compared using ANOVA or the Kruskal-Wallis test. Mean knowledge scores for HAV, HBV and HCV infections were 2.6 ± 1.5, 6.1 ± 2.4, and 3.6 ± 1.1, respectively. For HAV and HBV infections, the mean knowledge score significantly (P < 0.05) increased with age, level of counseling received and number of sources of information. However, for HCV infection the mean knowledge score significantly increased with decreasing age, increased educational level and increased annual family income. Contrary to HBV, a higher HAV and HCV knowledge score was observed among individuals with history of vaccination for HAV and HBV, seropositive status for HAV and HCV, and history of drug use. A sizeable proportion of adults in this study demonstrated an inadequate level of knowledge, especially about transmission routes. Health education must be focused on transmission and prevention methods, including the availability of a vaccine for HAV and HBV, especially among those with chronic liver disease.

Abstract
INTRODUCTION Given changes in sexual behaviors and norms in the United States, there is a need for current and representative data on sexual behaviors with particular interest in gender, age, and racial/ethnic group differences. AIM Given the limited data for Hispanics and for Puerto Rico (PR), we described patterns of sexual behaviors and characteristics among a sexually active sample (n=1,575) of adults aged 21-64 years in PR. MAIN OUTCOME MEASURES The main outcome measures for this study are sexual behaviors including age at sexual initiation, number of sexual partners, vaginal and anal intercourse, and oral sex, among others. METHODS Data from a population-based cross-sectional study in PR (2005-2008) was analyzed. The prevalence of sexual behaviors and characteristics was described by age-group and gender during the lifetime and in the past 12 months. RESULTS Overall, 96.8%, 81.6%, and 60.9% of participants had ever engaged in vaginal, oral and anal sex, respectively, whereas 23.7% were seropositive to any of the sexually transmitted infections under study. Sexual initiation≤15 years was reported by 37.8% of men and 21.4% of women; whereas 47.9% of men and 13.2% of women reported to have had ≥7 sexual partners in their lifetime. Approximately, 3% of women and 6% of men reported same-sex sexual practices, while history of forced sexual relations was reported by 9.6% of women and 2.5% of men. Sexual initiation≤15 years was more common among individuals aged 21-34 years (41.4% men and 33.6% women) as compared with older cohorts. Although having had ≥7 sexual partners over a lifetime among men was similar across age groups, this behavior decreased in older women cohorts. In both genders, the prevalence of oral and anal sex was also lower in the older age cohorts. CONCLUSION This study provides essential information that can help health professionals understand the sexual practices and needs of the population of PR.

Abstract
OBJECTIVE Despite the growing impact of the human immunodeficiency virus (HIV) epidemic in Puerto Rico (PR), limited epidemiological research on men who have sex with men (MSM) has been conducted. The aim of this study was to describe HIV-related risk behaviors in a sample of MSM in PR. METHODS A secondary data analysis of a household survey of the adult population of PR was performed in order to describe substance use and sexual practices related to HIV transmission and seropositivity for hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), HIV, and type 2 herpes simplex virus (HSV-2) in MSM. Data regarding substance use and sexual practices were collected using audio computer-assisted self-interviewing (A-CASI). Descriptive statistics were used to examine lifetime and recent (12 months) prevalence of substance use and sexual practices. RESULTS Of the 640 men interviewed, 41 (6.4%) reported having ever had sex with another man on at least one occasion. Approximately one-fourth of MSM reported having used marijuana (24.4%) and cocaine (24.4%) in the past 12 months. Nearly 42% of the MSM reported an early age of sexual initiation (< 15 years), and 61% reported having had at least 10 sexual partners in their lifetime. Seropositivity rates for HAV, HSV-2, HIV, HCV, and HBV were 43.3%, 32.4%, 7.3%, 4.9%, and 4.9%, respectively. CONCLUSION This is the first study to attempt to examine high-risk behaviors related to HIV in a population-based sample of MSM in PR. Concurrent efforts that will help to intensify research and prevention initiatives among MSM are necessary, especially those that will enhance awareness of screening for HIV, HCV, and other sexually transmitted infections, access to HAV and HBV vaccinations, substance use, and identification of social barriers.

Abstract
BACKGROUND Viral hepatitis and sexually transmitted infections (STIs) are key public health problems that pose an enormous risk for disease transmission in the general population. This study estimated, for the first time, prevalence estimates of serologic markers of HCV, HBV, HAV, HIV and HSV-2 in the adult population of Puerto Rico and assessed variations across sociodemographic and behavioral characteristics. METHODS A seroepidemiologic survey was employed using a stratified cluster probability sample of households in Puerto Rico. Participants completed a face-to-face interview, a self-administered questionnaire using an ACASI system, and provided blood specimens for antibody testing. Prevalence estimates of viral hepatitis, HIV and HSV-2 were estimated using a logistic regression model weighting for the probability of participation in each household block and the inverse of the probability of selection according to geographic strata, households' blocks, and sex distribution. RESULTS A total of 1,654 adults participated in the study. Seroprevalence estimates for HCV (2.3%, 95% CI: 1.3%-4.2%), HBV (3.1%, 95% CI: 2.0%-4.7%), and HSV-2 (22.3%, 95% CI: 18.5%-26.7%) in Puerto Rico are roughly in agreement with estimates obtained in the US population; however, HAV (41.3%, 95% CI: 36.9%-45.8%) and HIV (1.1%, 95% CI: 0.5%-2.3%) seroprevalence estimates in Puerto Rico were higher. The proportion of individuals that were unaware of their serostatus was as follows: 80% for HCV, 98.3% for HBV, 96.4% for HAV, 36.4% for HIV, and 97.8% for HSV-2. Post-stratification estimates of seroprevalence varied significantly by demographic and risk related characteristics. CONCLUSION This data underscore the disproportionate impact of some viral infections across selected population subgroups in Puerto Rico. A concerted island-wide effort is needed to strengthen viral hepatitis and STIs prevention and control strategies, support surveillance to monitor chronic infections, and ensure appropriate counseling, testing, and medical management of infected persons. Integration of HCV, HBV, and HSV-2 counseling into HIV existing prevention services and outreach through social networks might represent a valuable approach to reach high-risk individuals.
