A small but consistent literature from the United States suggests increased risk for smoking among lesbians and men who have
sex with men (MSM). Few studies have investigated smoking among MSM in other countries where different social norms and restrictions
on smoking in public apply. We measured smoking behaviours in a convenience sample of urban-dwelling young Canadian MSM (median
age 28 years). We compared the prevalence of smoking among MSM with that among other men in British Columbia (BC) using National
Population Health Survey data to compute an age-adjusted standardized prevalence ratio (SPR). Independent predictors of smoking
among MSM were identified using adjusted odds ratios (OR) with 95% confidence intervals (CI). Smoking during the previous
year was reported by twice as many MSM (54.5% of 354) as other men in BC (25.9%) (SPR = 1.94, 95% CI 1.48–2.59), with largest
differentials observed among men under 25 years of age. In multivariable analyses, smoking among MSM was significantly associated
with younger age (OR 0.94, CI 0.88–1.00 per year), greater number of depressive symptoms (OR 1.12, CI 1.06–1.19 per symptom)
and Canadian Aboriginal ethnicity (OR 2.64, CI 1.05–6.60). In summary, MSM in our study were twice as likely to smoke as other
men in BC; the greatest differences were observed among the youngest men. The design of effective prevention and cessation
programs for MSM will require identification of the age-dependent determinants of smoking initiation, persistence, and attempts
to quit.

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. 相似文献

Population-based estimates of human immunodeficiency virus (HIV) prevalence and risk behaviors among men who have sex with
men (MSM) are valuable for HIV prevention planning but not widely available, especially at the local level. We combined two
population-based data sources to estimate prevalence of diagnosed HIV infection, HIV-associated risk-behaviors, and HIV testing
patterns among sexually active MSM in New York City (NYC). HIV/AIDS surveillance data were used to determine the number of
living males reporting a history of sex with men who had been diagnosed in NYC with HIV infection through 2002 (23% of HIV-infected
males did not have HIV transmission risk information available). Sexual behavior data from a cross-sectional telephone survey
were used to estimate the number of sexually active MSM in NYC in 2002. Prevalence of diagnosed HIV infection was estimated
using the ratio of HIV-infected MSM to sexually active MSM. The estimated base prevalence of diagnosed HIV infection was 8.4%
overall (95% confidence interval [CI] = 7.5–9.6). Diagnosed HIV prevalence was highest among MSM who were non-Hispanic black
(12.6%, 95% CI = 9.8–17.6), aged 35–44 (12.6%, 95% CI = 10.4–15.9), or 45–54 years (13.1%, 95% CI = 10.2–18.3), and residents
of Manhattan (17.7%, 95% CI = 14.5–22.8). Overall, 37% (95% CI = 32–43%) of MSM reported using a condom at last sex, and 34%
(95% CI = 28–39%) reported being tested for HIV in the past year. Estimates derived through sensitivity analyses (assigning
a range of HIV-infected males with no reported risk information as MSM) yielded higher diagnosed HIV prevalence estimates
(11.0–13.2%). Accounting for additional undiagnosed HIV-infected MSM yielded even higher prevalence estimates. The high prevalence
of diagnosed HIV among sexually active MSM in NYC is likely due to a combination of high incidence over the course of the
epidemic and prolonged survival in the era of highly active antiretroviral therapy. Despite high HIV prevalence in this population,
condom use and HIV testing are low. Combining complementary population-based data sources can provide critical HIV-related
information to guide prevention efforts. Individual counseling and education interventions should focus on increasing condom
use and encouraging safer sex practices among all sexually active MSM, particularly those groups with low levels of condom
use and multiple sex partners

The purpose of the study was to determine the potential contribution of bisexual men to the spread of HIV in Los Angeles.
We compare the characteristics and behaviors of men who have sex with men and women (MSMW) to men who have sex with only women
(MSW) and men who have sex with only men (MSM) in Los Angeles. Men (N = 1,125) who participated in one of the two waves of data collection from 2005 to 2007 at the Los Angeles site for NIDA’s
Sexual Acquisition and Transmission of HIV—Cooperative Agreement Program were recruited using Respondent Driven Sampling.
Participants completed Audio Computer Assisted Self Interviews and received oral HIV rapid testing with confirmatory blood
test by Western Blot and provided urine specimens for detection of recent powder cocaine, crack cocaine, methamphetamine,
or heroin use. MSM, MSW, or MSMW were defined by the gender of whom they reported sex with in the past 6 months. Chi-square
tests and ANOVAs were used to test independence between these groups and demographic characteristics, substance use, and sexual
behaviors. We fit generalized linear random intercept models to predict sexual risk behaviors at the partner level. Men were
mostly of low income, unemployed, and minority, with many being homeless; 66% had been to jail or prison, 29% had ever injected
drugs, and 25% had used methamphetamine in the past 30 days. The sample had high HIV prevalence: 12% of MSMW, 65% of MSM,
and 4% of MSW. MSMW were behaviorally between MSW and MSM, except that more MSMW practiced sex for trade (both receiving and
giving), and more MSMW had partners who are drug users than MSW. Generalized linear random intercept models included a partner-level
predictor with four partner groups: MSM, MSMW-male partners, MSMW-female partners, and MSW. The following were significantly
associated with unprotected anal intercourse (UAI): MSW (AOR 0.15, 95% CI 0.08, 0.27), MSMW-female partners (AOR 0.4, 95%
CI 0.27, 0.61), HIV-positive partners (AOR 2.03, 95% CI 1.31, 3.13), and being homeless (AOR 1.37, 95% CI 1.01, 1.86). The
factors associated with giving money or drugs for sex were MSMW-female partners (AOR 1.70, 95% CI 1.09, 2.65), unknown HIV
status partners (AOR 1.72, 95% CI 1.29, 2.30), being older (AOR 1.02, 95% CI 1.00, 1.04), history of incarceration (AOR 1.64,
95% CI 1.17, 2.29), and being homeless (AOR 1.73, 95% CI 1.27, 2.36). The following were associated with receiving money or
drugs for sex: MSW (AOR 0.53, 95% CI 0.32, 0.89), African American (AOR 2.42, 95% CI 1.56, 3.76), Hispanic (AOR 1.85, 95%
CI 1.12, 3.05), history of incarceration (AOR 1.44, 95% CI 1.04, 2.01), history of injecting drugs (AOR 1.57, 95% CI 1.13,
2.19), and had been recently homeless (AOR 2.14, 95% CI 1.57, 2.94). While overall HIV-positive MSM had more UAI with partners
of any HIV status than MSMW with either partner gender, among HIV-positive MSMW, more had UAI with HIV-negative and HIV status
unknown female partners than male partners. Findings highlight the interconnectedness of sexual and drug networks in this
sample of men—as most have partners who use drugs and they use drugs themselves. We find a concentration of risk that occurs
particularly among impoverished minorities—where many men use drugs, trade sex, and have sex with either gender. Findings
also suggest an embedded core group of drug-using MSMW who may not so much contribute to spreading the HIV epidemic to the
general population, but driven by their pressing need for drugs and money, concentrate the epidemic among men and women like
themselves who have few resources. 相似文献

Men who have sex with men (MSM) carry the burden of HIV infection in China. Outside of China, a history of childhood sexual abuse (CSA) has been associated with HIV-related risks (behavioral, sexual, and mental health outcomes) among MSM. We therefore evaluated the relationship between CSA and these HIV-related risks among MSM in China. Cross-sectional data were collected via a survey from gay websites and social networking applications from MSM in 30 provinces in mainland China during a 3-month period in 2014 and 2015. Overall, 999 screened MSM who responded to questions on CSA were included. Multinomial logistic regression models—adjusted for sociodemographic confounders—showed that men who reported experiencing regular CSA and contact CSA, respectively, were more likely to use substances (adjusted odds ratio [AOR], 1.91; 95% confidence interval [CI] 1.39–2.62 and AOR, 1.70; 95% CI 1.25–2.31), had a history of sexually transmitted infections (AOR, 1.81; 95% CI 1.29–2.55 and AOR, 1.65; 95% CI 1.18–2.96), had more male sexual partners (AOR, 1.06; 95% CI 1.04–1.09 and AOR, 1.05; 95% CI 1.03–1.08), engaged in more condomless sex with men (AOR, 1.89; 95% CI 1.39–2.56 and AOR, 1.72; 95% CI 1.29–2.30), and experienced more psychological distress (AOR, 1.05; 95% CI 1.02–1.08 and AOR, 1.05; 95% CI 1.03–1.08). Both frequent and contact forms of CSA were positively associated with HIV-related risks among MSM, suggesting that general CSA prevention strategies and interventions are needed to support this population. 相似文献

Circumcision and HIV Infection among Men Who Have Sex with Men in Britain: The Insertive Sexual Role
Rita Doerner Eamonn McKeown Simon Nelson Jane Anderson Nicola Low Jonathan Elford 《Archives of sexual behavior》2013,42(7):1319-1326
The objective was to examine the association between circumcision status and self-reported HIV infection among men who have sex with men (MSM) in Britain who predominantly or exclusively engaged in insertive anal intercourse. In 2007–2008, a convenience sample of MSM living in Britain was recruited through websites, in sexual health clinics, bars, clubs, and other venues. Men completed an online survey which included questions on circumcision status, HIV testing, HIV status, sexual risk behavior, and sexual role for anal sex. The analysis was restricted to 1,521 white British MSM who reported unprotected anal intercourse in the previous 3 months and who said they only or mostly took the insertive role during anal sex. Of these men, 254 (16.7 %) were circumcised. Among men who had had a previous HIV test (n = 1,097), self-reported HIV seropositivity was 8.6 % for circumcised men (17/197) and 8.9 % for uncircumcised men (80/900) (unadjusted odds ratio [OR], 0.97; 95 % confidence interval [95 % CI], 0.56, 1.67). In a multivariable logistic model adjusted for known risk factors for HIV infection, there was no evidence of an association between HIV seropositivity and circumcision status (adjusted OR, 0.79; 95 % CI, 0.43, 1.44), even among the 400 MSM who engaged exclusively in insertive anal sex (adjusted OR, 0.84; 95 % CI, 0.25, 2.81). Our study provides further evidence that circumcision is unlikely to be an effective strategy for HIV prevention among MSM in Britain. 相似文献

We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of,
perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP)
and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed
and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted
to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using
a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were
found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that
HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI:
2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR,
95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied
with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic
MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential
experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM.

Criminal justice practices in the USA disproportionately affect sexual and racial/ethnic minority men, who are at higher risk of incarceration. Previous research demonstrates associations between incarceration and sexual risk behaviors for men who have sex with men (MSM). However, little of this work focuses on young MSM (YMSM), particularly HIV-infected YMSM, despite nearly one-third reporting engagement in sexual risk behaviors, such as transactional sex. We therefore explored the association between incarceration and transactional sex among HIV-infected YMSM. We recruited 97 HIV-infected YMSM across 14 clinical sites in urban centers from August 2015 to February 2016. We used multivariate logistic regression to examine the relationship between incarceration and transactional sex among YMSM. The majority was 24 years old (78%) and racial/ethnic minority (95%); over half were not in school and reported an annual income of <?$12,000. In the multivariate model, having ever been incarcerated (aOR?=?3.20; 95% CI 1.07–9.63) was independently associated with a history of transactional sex. Being 24 years vs. younger (aOR?=?9.68; 95% CI 1.42–65.78) and having ever been homeless (aOR?=?3.71, 95% CI 1.18–11.65) also remained independently associated with a history of transactional sex. This analysis fills a gap in the literature by examining the relationship between incarceration and transactional sex among HIV-infected YMSM. Facilitating youths’ engagement with social services available in their HIV clinic may serve as a key strategy in promoting health. Public health efforts need to address social-structural factors driving disproportionate rates of arrest and incarceration and related harms among this population. 相似文献

Although criminal justice involvement has repeatedly been associated with human immunodeficiency virus (HIV)/sexually transmitted
infection prevalence and sexual risk behaviors, few studies have examined whether arrest or incarceration uniquely contributes
to sexually risky behavior. We examined the temporal relationship between criminal justice involvement and subsequent sexual
HIV risk among men in methadone maintenance treatment in New York City. A random sample of 356 men was interviewed at baseline
(time 1), 6-month (time 2), and 12-month (time 3) follow-ups. Propensity score matching, negative binomial, and multiple logistic
regression were used to isolate and test the effect of time 2 arrest and incarceration on time 3 sexual risk behaviors. Incidence
of time 2 criminal justice involvement was 20.1% for arrest and 9.4% for incarceration in the prior 6 months. Men who were
arrested at time 2 demonstrated increased number (adjusted incidence rate ratio [IRR] = 1.62; 95% confidence intervals [CI] = 1.11,
2.37) and proportion (IRR = 1.36; 95% CI = 1.07, 1.72) of unprotected vaginal sex acts at time 3. Men incarcerated at time
2 displayed increased number (IRR = 2.07; 95% CI = 1.23, 3.48) and proportion (IRR = 1.45; 95% CI = 1.06, 1.99) of unprotected
vaginal sex acts at time 3. Within this sample of drug-involved men, arrest and incarceration are temporally associated with
and may uniquely impact successive sexual risk-taking. Findings underscore the importance of HIV prevention interventions
among individuals with low-intensity criminal justice involvement. Developing prevention efforts aimed at short-term incarceration,
community reentry, and alternatives to incarceration settings will address a large and under-researched segment of the criminal
justice population. Alternative approaches to current criminal justice policy may result in public health benefits. 相似文献

This study analyzed data from a large prospective epidemiologic cohort study among men who have sex with men (MSM), the Multicenter AIDS Cohort Study, to assess syndemic relationships among Black MSM in the cohort (N = 301). We hypothesized that multiple interconnections among psychosocial health conditions would be found among these men, defining syndemic conditions. Constituents of syndemic conditions measured included reported depression symptoms, sexual compulsiveness, substance use, intimate partner violence (IPV), and stress. We found significant evidence of syndemics among these Black men: depression symptoms were independently associated with sexual compulsiveness (odds ratios [OR]: 1.88, 95% CI = 1.1, 3.3) and stress (OR: 2.67, 95% CI = 1.5, 4.7); sexual compulsiveness was independently associated with stress (OR: 2.04, 95% CI = 1.2, 3.5); substance misuse was independently associated with IPV (OR: 2.57, 95% CI = 1.4, 4.8); stress independently was associated with depression symptoms (OR: 2.67, 95% CI = 1.5, 4.7), sexual compulsiveness (OR: 2.04, 95% CI = 1.2, 3.5) and IPV (OR: 2.84, 95% CI = 1.6, 4.9). Moreover, men who reported higher numbers of syndemic constituents (three or more conditions) reportedly engaged in more unprotected anal intercourse compared to men who had two or fewer health conditions (OR: 3.46, 95% CI = 1.4–8.3). Findings support the concept of syndemics in Black MSM and suggest that syndemic theory may help explain complexities that sustain HIV-related sexual transmission behaviors in this group. 相似文献

Many men who have sex with men (MSM) in low and middle income countries search for male sexual partners via social media in part due to societal stigma and discrimination, yet little is known about the sexual risk profiles of MSM social media users. This cross-sectional study investigates the prevalence of social media use to find male sex partners in Hanoi, Vietnam and examines associations between social media use and sociodemographic and behavioral characteristics, including levels of internalized, perceived and enacted stigma, high-risk sexual behaviors, and HIV testing. 205 MSM were recruited from public venues where MSM congregate as well as through snowball sampling and completed an anonymous survey. MSM who found their male sexual partners using social media in the last year were more likely to have completed a university or higher degree (aOR 2.6; 95% CI 1.2–5.7), experience high levels of MSM-related perceived stigma (aOR 3.0; 95% CI 1.1–8.0), and have more than ten lifetime male sexual partners (aOR 3.2; 95% CI 1.3–7.6) compared to those who did not use social media. A niche for social media-based interventions integrating health and stigma-reduction strategies exists in HIV prevention programs for MSM. 相似文献

Studies have found that between 14% and 46% of US men who have sex with men (MSM) consistently report “barebacking” behavior
(i.e., intentional unprotected anal intercourse) with other men. This is of public health significance because MSM continue to constitute more
than 50% of new HIV infections in the USA. Men who self-identify as barebackers may represent a different and unique subset
of MSM with distinct HIV prevention needs. In 2007, 227 HIV seronegative MSM recruited through modified respondent-driven
sampling completed an interviewer-administered survey which assessed barebacker identity (i.e., personally identifying with
the barebacker scene), demographics, sexual risk behaviors, psychosocial variables, and drug/alcohol use. Bivariate and multivariable
logistic regression procedures were used to examine predictors of barebacker identity in relation to HIV risk behavior. Overall,
31% of participants identified as a barebacker. In bivariate analyses, lower education (OR = 1.76; 95% CI = 0.99–3.13; p < 0.05), a current drinking problem (OR = 2.34, 95% CI = 1.29–4.23; p < 0.01), higher levels of HIV treatment optimism (OR = 1.06; 95% CI = 1.01–1.12; p < 0.05), meeting sexual partners at private sex parties (OR = 2.47; 95% CI = 1.28–4.74; p < 0.01) or at bars/cubs (OR = 1.97; 95% CI = 1.10–3.52; p < 0.05), and engaging in serodiscordant unprotected insertive anal sex (OR = 3.42; 95% CI = 1.27–9.21; p < 0.01) significantly predicted barebacker identification compared to those with no barebacker identification. In a multivariable
model, barebackers were more likely to screen in for alcohol abuse (adjusted OR = 2.16; 95% CI = 1.09–4.27; p < 0.05) and engage in serodiscordant unprotected insertive anal sex (adjusted OR = 3.17; 95% CI = 1.09–9.20; p < 0.05) compared to their non-barebacker counterparts. No significant differences were found in serodiscordant unprotected
receptive anal sex between barebackers and non-barebackers. These findings suggest that barebacker identity is related to
intentional HIV sexual risk taking and alcohol abuse. Furthermore, strategic positioning (i.e., engaging in insertive rather
than receptive sex) might be associated with barebacker identification and may indicate a harm-reduction strategy being used
among some HIV-uninfected MSM to reduce their risk of becoming infected. Additional research is warranted to understand the
social identity of barebacking among MSM in order to develop more nuanced prevention strategies. 相似文献

Little is known about the patterns and types of intimate partner abuse in same-sex male couples, and few studies have examined
the psychosocial characteristics and health problems of gay and bisexual men who experience such abuse. Using a cross-sectional
survey sample of 817 men who have sex with men (MSM) in the Chicago area, this study tested the effect of psychological and
demographic factors generally associated with intimate partner abuse and examined their relationship to various health problems.
Overall, 32.4% (n = 265) of participants reported any form of relationship abuse in a past or current relationship; 20.6% (n = 168) reported a history of verbal abuse (“threatened physically or sexually, publicly humiliated, or controlled”), 19.2%
(n = 157) reported physical violence (“hit, kicked, shoved, burned, cut, or otherwise physically hurt”), and 18.5% (n = 151) reported unwanted sexual activity. Fifty-four percent (n = 144) of men reporting any history of abuse reported more than one form. Age and ethnic group were unrelated to reports
of abuse. Depression and substance abuse were among the strongest correlates of intimate partner abuse. Men reporting recent
unprotected anal sex were more likely to also report abuse, Wald (1, n = 773) = 9.02, p < .05, Odds Ratio (OR) = 1.61, Confidence Interval (CI) = 1.18–2.21. We discuss psychosocial issues faced by gay and bisexual
men who experience intimate partner abuse as they may pertain to interventions among this group. 相似文献

Incarceration is strongly associated with HIV infection and may contribute to viral transmission by disrupting stable partnerships
and promoting high-risk partnerships. We investigated incarceration and STI/HIV-related partnerships among a community-based
sample recruited for a sexual behavior interview while frequenting venues where people meet sexual partners in a North Carolina
city (N = 373). Men reporting incarceration in the past 12 months were more likely than men without recent incarceration to experience
multiple new sexual partnerships (unadjusted prevalence ratio [PR] 1.8, 95% confidence interval [CI]: 1.1–3.1) and transactional
sex defined as trading sex for money, goods, or services (unadjusted PR: 4.0, 95% CI: 2.3–7.1) in the past 4 weeks. Likewise,
women who were ever incarcerated were more likely than never-incarcerated women to experience recent multiple new partnerships
(unadjusted PR: 3.1, 95% CI: 1.8–5.4) and transactional sex (unadjusted PR: 5.3, 95% CI: 2.6–10.9). Sexual partnership in
the past 12 months with someone who had ever been incarcerated versus with partners with no known incarceration history was associated with recent multiple new partnerships (men: unadjusted PR
2.0, 95% CI 1.4–2.9, women: unadjusted PR 4.8, 95% CI 2.3–10.1) and transactional sex (men: unadjusted PR 3.3, 95% CI 1.7–6.6,
women: unadjusted PR 6.1, 95% CI 2.4–15.4). Adjustment for demographic and socioeconomic variables had minimal effect on estimates.
However, the strong overlap between incarceration, partner incarceration, and substance abuse had substantial effects in multivariable
models. Correctional-facility and community-based HIV prevention, with substance abuse treatment, should reach currently and
formerly incarcerated individuals and their sexual partners.

During the last decade, the incidence of male urethritis stopped declining in France. Risk factors associated with unprotected
intercourse have been extensively studied in men who have sex with men, but not in men in general. The purpose of the study
was to determine major risk factors for urethritis among men and to describe the sociodemographic and medical characteristics
of this population in 2005. We conducted a prospective case-crossover study of sexual behaviors among men with acute urethritis
attending at general practitioners or sexually transmitted infection (STI) clinics in France. Each patient filled out a selfcompleted
questionnaire focusing on sociodemographic characteristics, and on sexual behaviors for the month before urethritis onset
and for the preceding 3 months. The doctor reported medical information on a separate questionnaire. Between January and September
2005, 121 cases of male urethritis, defined as recent-onset pain on micturition and/or purulent or mucoid discharge, were
included. Median age was 33 years, 22.3% were MSM, 55.1% were single, and 72.0% had at least high school education. Conditional
logistic regression analysis showed that intercourse with only casual partners or with both casual and steady partners (OR = 2.6,
CI 95%: 0.8–8.7, and OR = 8.7, CI 95%: 2.7–28.0), as well as inconsistent condom use (OR = 5.8, CI 95%: 1.7–19.2) significantly
increased the risk of male urethritis. STI prevention campaigns should continue to focus on consistent condom use and should
not neglect men over 30 years of age. 相似文献

Race-based sexual preferences in the online profiles of men who have sex with men (MSM) may be relevant for understanding the sexual health of this population, including racial/ethnic disparities in HIV infection. In October 2011, a content analysis was conducted of the profiles of Boston-area members of a racially diverse website for MSM. The present analysis formatively examined the use of demographic and partner selection criteria by race/ethnicity appearing in the profiles of men who indicated race-based partner preferences (n = 89). Latino men were the most frequently preferred race (54 %), followed by White (52 %), Black (48 %), and Asian (12 %) men. In separate multivariable models adjusted for age and HIV status disclosure, wanting low-risk foreplay was associated with a preference for White men (aOR) = 4.27; 95 % CI = 1.70–10.75; p = 0.002), while wanting group sex was associated with a preference for Black (OR = 2.28; 95 % CI = 1.08–4.81; p = 0.03) and Latino men (OR = 2.56; 95 % CI = 1.25–5.23; p = 0.01). Future studies are needed to replicate findings in larger online samples. Mixed-methods research should explore how racial and behavioral preferences impact the sexual mixing patterns and health of MSM online in urban areas. 相似文献
