Discordance between self-perceived HIV risk and actual risk-taking may impede efforts to promote HIV testing among young adult men-who-have-sex-with-men (YMSM) in the United States (US). Understanding the extent of, and reasons for, the discordance of HIV risk self-perception, HIV risk-taking and voluntary HIV testing among black, Hispanic and white YMSM could aid in the development of interventions to increase HIV testing among this higher HIV risk population. HIV-uninfected 18–24-year-old black, Hispanic, and white YMSM were recruited from across the US through multiple social media websites. Participants were queried about their voluntary HIV testing history, perception of currently having an undiagnosed HIV infection, and condomless anal intercourse (CAI) history. We assessed the association between previous CAI and self-perceived possibility of currently having an HIV infection by HIV testing status using Cochran-Mantel-Haenszel testing. Of 2275 black, Hispanic and white social media-using 18–24 year-old YMSM, 21% had never been tested for HIV voluntarily, 87% ever had CAI with another man, 77% believed that it was perhaps possible (as opposed to not possible at all) they currently could have an undiagnosed HIV infection, and 3% who reported CAI with casual or exchange partners, but had not been tested for HIV, self-perceived having no possibility of being HIV infected. Of 471 YMSM who had not been HIV tested, 57% reported CAI with casual or exchange partners, yet self-perceived having no possibility of being HIV infected. Per the Cochran-Mantel-Haenszel test results, among those reporting HIV risk behaviors, the self-perception of possibly being HIV-infected was not greater among those who had never been tested for HIV, as compared to those who had been tested. Future interventions should emphasize promoting self-realization of HIV risk and translating that into seeking and accepting voluntary HIV testing among this higher HIV risk population.  相似文献

Associations between individual- and family-level psychosocial factors and sexual behavior were examined among 325 adolescents ages 10–18 in rural Kenya. History of sexual activity was reported by 51% of males and 30% of females. Among those reporting sex within the past year, 64% of males and 32% of females had multiple partners; 85% of males and 54% of females reported not using a condom at last sex. Multivariate logistic regression modeling demonstrated sexually active adolescents were significantly more likely to be older, male, more accepting of risky behavior, and have greater perceived HIV risk, caregiver social support, social support related to HIV, and emotional problems. Youths reporting high-risk behavior (unprotected sex or multiple partners) were significantly more likely to be younger, male, and have lower sex-related self-efficacy, lower caregiver monitoring, and more externalizing problems. Future studies should evaluate HIV prevention interventions targeting improvements in mental health and family relationships.  相似文献

HIV infection rates are dramatically increasing in the Russian Federation. Epidemiological studies indicate that the greatest rise of HIV incidence has been among injection drug users (IDU). Young adults (N = 188) who reported injecting drug use completed surveys and interviews that assessed injection drug use behavior, sexual behavior, and HIV‐related knowledge. The average age of participants was 21.3 years. Multiple linear regression analysis found male gender and younger age at sexual debut was positively and significantly associated with having multiple sexual partners. Gender moderated the effects of sexual debut and number of times injected drugs were used in the past month. Males who initiate sex at a younger age were more likely to report multiple sex partners and females who reported higher frequency of drug use were more likely to report multiple sex partners. Gender is an important factor, as well as moderator of risk behavior among Russian injection drug users. Delaying sexual debut, particularly for males, may be an effective strategy to reduce subsequent risk behavior. Prevention efforts among IDUs need to address sexual risk behavior in conjunction with injection risk behavior.  相似文献

Many men who have sex with men (MSM) do not use condoms with their main partners, especially if both parties are of the same HIV status. However, significant proportions of MSM have never tested or recently tested and are unaware of their main partners’ HIV status. A cross-sectional survey was conducted among 524 MSM in Jiangsu, China in 2013–2014. Time-location sampling and online convenience sampling were used to recruit participants. We compared awareness of HIV status and recent HIV testing between participants who had main partners versus those who did not, and identified factors associated with recent HIV testing among men in main partnerships. Participants in main partnerships were significantly more likely to report recent HIV testing and being HIV-negative instead of HIV-unknown compared to participants in casual partnerships only. Overall, 74.5 % of participants were aware of their main partners’ HIV status. Among participants in main partnerships, those who had 2–5 male anal sex partners in the past 6 months and those who reported that their partners were HIV-negative had 2.36 (95 % CI 1.12, 4.97) and 4.20 (95 % CI 2.03, 8.70) fold greater odds of being tested in the past year compared to those who had main partners only and those whose partners were HIV-positive/unknown, respectively. Chinese MSM in main partnerships might be practicing serosorting and may be at lower risk for HIV infection due to increased awareness of main partners’ HIV status and higher uptake of recent testing.  相似文献

A significant minority of Australian men who have sex with men (MSM) have never been tested for HIV and many men do not test as often as recommended. Using data from 1770 HIV-negative and untested MSM collected in a national, online survey, we compared men who had never tested for HIV with those who had tested over 12 months ago and men who had tested over 12 months ago with those that had tested in the past year. Two multivariate logistic regression models were constructed. Compared with men tested over 12 months ago, untested men were younger, less educated, less likely to have unprotected anal intercourse with a regular male partner, less likely to have sought advice from a doctor, nurse or community organisation, more likely to expect HIV-negative disclosure, had fewer gay friends and spent more time using social networking websites. Compared with men who had tested over 12 months ago, men who had tested within the last year were younger, more likely to expect HIV-negative disclosure and disclose to casual partners, more likely to have sought advice from a doctor or nurse, had attended gay pools, gyms or beaches and had more gay friends and more male sex partners. Our findings suggest that the Internet and sex education in schools are important ways to promote HIV testing to untested MSM. Testing reinforcement messages delivered through gay community outreach and primary care will reach previously tested MSM.  相似文献

Little is known about the HIV testing behaviours among Caribbean youth. The purpose of this study was to determine the prevalence of and the factors associated with HIV testing in Caribbean youth. Data were used from population-based surveys in three Caribbean countries: Guyana, Haiti and the Dominican Republic. Chi-square tests and multiple logistic regression models were fitted to examine the associations between independent correlates and ever being tested of HIV. The proportion of youth reporting HIV testing ranged from 17% in Haiti to 48% in the Dominican Republic. Across all countries increased odds of ever being tested for HIV was associated with ever being married, having five or more lifetime partners, and knowing someone who was living with or had died from HIV. Male gender and rural residence were correlated with decreased odds of HIV testing. Low levels of HIV testing were observed among sexually experienced youth in three Caribbean countries. Men, younger and never married youth were less likely to be have been tested for HIV. Outreach and public health messages targeting these youth should be implemented. Programmes that assist youth in accurately assessing their risk behaviours are also required to improve HIV testing.  相似文献

Very little is currently known about factors impacting the prevalence of cervical cancer screening among women living with HIV-AIDS (WLHA). To better understand this issue, we surveyed low-income, medically underserved women receiving subsidized gynecologic care through an integrated HIV clinic. A self-administered questionnaire was completed by 209 women who self-identified as HIV positive. A total of 179 subjects (85.7%) reported having had a Pap test in the last three years. The majority of WLHA (95%) knew that the Pap test screens for cervical cancer. However, overall knowledge of cervical cancer risk factors, such as multiple sexual partners or sex with a man with multiple partners, was low (43% and 35%, respectively). Unscreened women were younger and more likely to be single with multiple current sexual partners. In multivariable analyses, the only factors associated with Pap testing were a woman's perception that her partner wants her to receive regular screening (aOR 4.64; 95% CI: 1.15–23.76; p?=?.04), number of clinic visits during the past year (aOR 1.36, 95% CI: 1.05–1.94; p?=?.04) and knowledge that the need for a Pap test does not depend on whether or not a woman is experiencing vaginal bleeding (aOR 6.52, 95% CI: 1.04–49.71; p?=?.05). We conclude that support from male partners in addition to effective contact with the health system and knowledge of cervical cancer risk factors influence Pap utilization among low-income WLHA. Future measures to improve the care for this population should increase knowledge of cervical cancer risk factors and encourage social support for cervical cancer screening among WLHA.  相似文献

HIV infections in Peru are concentrated among men who have sex with men (MSM) and transgender women (TW). HIV testing rates among them remain low, delaying entrance into care. We assessed the prevalence of frequent HIV testing (at least every 6 months) and associated factors among 310 MSM and TW who attend sexual health clinics in Lima, Peru, and who reported that they were HIV seronegative or unaware of their status. Only 39% of participants tested frequently, and 22% had never tested; 29% reported that they were at low or no risk for acquiring HIV. Reporting low or no risk for acquiring HIV was associated with frequent testing (adjusted prevalence ratio [aPR] = 1.53, 95% CI 1.13–2.08); those reporting unprotected anal sex were less likely to test frequently (aPR = 0.66, 95% CI 0.50–0.87). HIV prevalence was 12% and did not vary by risk perception categories. This at-risk population tests infrequently and may not understand the risk of having unprotected sex.  相似文献

The objective of this study was to determine how injection drug users' (IDUs) HIV-risk behavior differs with primary and other sex partners. Interviews were conducted with injection drug users from a needle exchange program (n = 243). Those with one sexual partner were more likely to report never using condoms with primary partners than were those with more than one partner (74% vs. 54%, p < 0.001). Those with more than one partner differed, between primary and other sexual partners, in their disclosure of HIV and IDU status, condom use, and drug use in combination with sex. Primary sexual partners of IDUs are placed at risk from IDUs' risk behavior with other sexual partners. Those planning HIV-risk reduction interventions for IDUs should consider risk behavior with primary partners separately from behavior with other partners. Evaluation of intervention effects should use partner-specific assessments of risk behavior.  相似文献

Older adults (age 50 +) are less likely to be tested for HIV and are diagnosed at a later disease stage than younger individuals. To examine the barriers and facilitating factors to testing in this age group, interview data from 35 older men and women who tested HIV positive at age 50 or older were analysed. Participants described a variety of pathways to testing, related to gender, sexual orientation, drug use, and era of the epidemic. Older gay and bisexual men described three trajectories: proactively seeking out testing, delaying testing due to fear and hopelessness, and denying exposure to HIV. Heterosexual drug users and their partners followed two trajectories, depending on the phase of the epidemic: (1) delay due to the lack of knowledge or perceived risk for infection, and (2) delay due to psychological barriers and drug use, despite recognizing their risk. Finally, heterosexual non-drug-users were unaware of their risk. Across risk groups, physical symptoms and encouragement from health care providers were the primary triggers that facilitated testing. The finding that risk perception was a necessary, but not sufficient, condition for undergoing HIV testing suggests that interventions need to reduce barriers and encourage earlier HIV testing among older adults, in addition to promoting risk awareness.  相似文献

This study investigates socio-demographic, behavioral, psychological, and structural factors associated with self-reported HIV/STD testing and willingness to test among 1,938 Chinese migrants. Overall, 6% and 14% of participants had ever been tested for HIV and STD, respectively. The results of multivariate analyses indicate that working at entertainment sectors, engaging in commercial sex, and utilization of health care were positively associated with both HIV and STD testing. Younger age, selling blood, perceived peer sexual risk involvement, and satisfaction with life were associated with HIV testing only. Female gender, early sexual debut, multiple sexual partners, and perceived vulnerability to HIV/STD were associated with STD testing only. Male gender, having premarital sex, perceived higher severity of and vulnerability to HIV/STD, and utilization of health care were associated with willingness to be tested for both HIV and STD. Interventions designed to raise the perception of vulnerability to HIV/STD and to improve access to and utilization of health care may be effective in encouraging more HIV testing in this vulnerable population.  相似文献

In Cambodia, despite great achievements in reducing the prevalence of HIV in the general population, reducing new HIV infections among young at-risk women remains a challenge. This study was designed to examine the prevalence of risky behaviors of sexually active female youth in Cambodia and to explore risk factors associated with engagement in transactional sex. We surveyed sexually active female youth aged 10–24 enrolled at risk “hotspots” in eight provinces in Cambodia. We collected data on demographic factors, sexual behavior, and factors hypothesized to be associated with transactional sex. Multivariable logistic regression was used to identify associations between demographic and sexual behavior and transactional sex. Of the 280 respondents, the mean age was 21.2, and 48.1% had been paid for sex in the past year. After adjustment, at-risk females who were never have been married (adjusted odds ratio (AOR) 3.40, 95% confidence interval (CI)?=?1.65–6.97), have completed less than 6 years of school (AOR 3.26, 95% CI?=?1.60–6.66), have 1 or more parents who had died (AOR 4.34, 95% CI?=?2.00–9.38), be a heavy alcohol drinker (AOR 3.58, 95% CI?=?1.78–7.18), have used a condom with their boyfriend during last sexual encounter (AOR 3.50, 95% CI?=?1.68–7.32), and have ever had an HIV test (AOR 3.51, 95% CI?=?1.68–7.32) were more likely to engage in sex work. Our findings suggest that prevention strategies for female youth at risk of engagement in sex work should include upstream structural interventions that aim to encourage girls' education and empowerment. In addition, tailored sex education and behavior change messaging about the risks of heavy drinking, condom use with romantic partners, and the importance of frequent HIV testing for at-risk youth and sex workers should be designed and delivered to youth currently engaging in sex work.  相似文献

The primary mode of HIV transmission in South Africa is heterosexual sexual behavior. HIV prevention research specifically focusing on men in South Africa is limited. We assessed self-reported HIV risk behaviors in 1,181 men ages 18 to 45 years in randomly selected neighborhoods in Eastern Cape Province, South Africa. Older men were less likely to report having multiple partners. Religiosity was a protective factor for condom use and unprotected sex with steady partners. Discussing using condoms was a protective factor for condom use and unprotected sex with both steady and casual partners. Having a child was associated with decreased condom use with steady partners and employment was associated with decreased condom use with casual partners. The findings suggest the need for HIV risk-reduction behavioral interventions tailored for South African men with regard to age, religiosity, and types of sexual partners. Implications for the development of such interventions are discussed.  相似文献

Past studies have used various methods to assess perceived risk of HIV infection; however, few have included multiple items covering different dimensions of risk perception or have examined the characteristics of individual items. This study describes the use of Item Response Theory (IRT) to develop a short measure of perceived risk of HIV infection scale (PRHS). An item pool was administered by trained interviewers to 771 participants. Participants also completed the risk behavior assessment (RBA) which includes items measuring risky sexual behaviors, and 652 participants completed HIV testing. The final measure consisted of 8 items, including items assessing likelihood estimates, intuitive judgments and salience of risk. Higher scores on the PRHS were positively associated with a greater number of sex partners, episodes of unprotected sex and having sex while high. Participants who tested positive for HIV reported higher perceived risk. The PRHS demonstrated good reliability and concurrent criterion-related validity. Compared to single item measures of risk perception, the PRHS is more robust by examining multiple dimensions of perceived risk. Possible uses of the measure and directions for future research are discussed.  相似文献

We examined the association of individual demographic and behavioral attributes, partnership (dyad) and social network characteristics with unprotected sex in the heterosexual dyads of IDUs in St. Petersburg, Russia. Of the individual-level characteristics female gender and younger age; and of the dyad-level characteristics sharing injecting equipment, social exposure to the sex partner (“hanging out with” or seeing each other daily), and both partners self-reporting being HIV infected were associated with unprotected sex. Although self-reported HIV discordant couples were less likely to engage in unprotected sex, it was reported in over half of self-reported HIV discordant relationships. This study highlights the intertwining of sexual risk and injecting risk, and the importance of sero-sorting based on perceived HIV status among IDU sexual partnerships in St. Petersburg, Russia. A combination of social network and dyad interventions may be appropriate for this population of IDUs, especially for IDUs who are both injecting and sex partners, supported by free and confidential rapid HIV testing and counseling services to provide a comprehensive response to the wide-spread HIV epidemic among IDUs in St. Petersburg.  相似文献

Previous studies suggested a rapid increase of HIV prevalence among men who have sex with men (MSM) in China in recent years, from 0.4% in 2004 to 5.8% in 2006. However, some MSM had never been tested for HIV. In order to expand the accessibility to HIV testing, understanding HIV-testing behavior and barriers among MSM is important. Using data collected from 307 young migrant MSM (aged 18-29 years) in 2009 in Beijing, we aimed to identify psychological and structural barriers to HIV testing. MSM were recruited through peer outreach, informal social networks, Internet outreach, and venue-based outreach. Participants completed a confidential self-administered questionnaire. Results show that about 72% of MSM ever had an HIV test. Logistic regression analysis indicated that the HIV-testing behavior was associated with sexual risk behaviors (e.g., multiple sexual partners and inconsistent condom use for anal sex) and history of sexually transmitted diseases. Eighty four MSM (28%) who never had an HIV test reported that the psychological barriers mainly were perceived low risk of HIV infection and fears of being stigmatized. The structural barriers reported inconvenience of doing test and lack of confidentiality. Future HIV prevention programs should be strengthened among MSM to increase their awareness of HIV risk. Efforts are needed to increase access to quality and confidential HIV testing among MSM and reduce stigma against MSM.  相似文献

Data from 307 young migrant men who have sex with men (MSM) in Beijing were analyzed to examine bisexual behavior and the associated sociodemographic and behavioral factors among Chinese young migrant MSM. More than one-fourth (27%) of the MSM were also concurrently engaged in sexual behavior with women (MSMW). Among MSMW, 8.4% were infected with HIV, and 10.8% with Syphilis, compared to 4.9% and 23.7%, respectively, among men who have sex with men only (MSM-only). Various HIV-related risk behaviors among MSMW were similar to those of MSM-only, such as unprotected anal sex, multiple sexual partners, involvement in commercial sex, and substance use. Compared with MSM-only, MSMW were less likely to have tested for HIV, to participate in HIV prevention activities, and were less knowledgeable about condom use and HIV/AIDS. MSMW also had a higher rate of unprotected sex with female stable sexual partners than with male stable sexual partners (79.5% vs. 59.5%). Results indicated that MSMW were at a very high risk for both HIV infection and transmission. Intervention efforts are needed to target this subgroup of MSM and promote AIDS knowledge and HIV/STD testing among MSMW, and to reduce HIV transmission through MSM's bisexual behavior.  相似文献

The present study reports sexual risk factors associated with HIV infection among men attending two sexually transmitted disease (STD) clinics in Pune, India and compares these behaviours between young and older men. Between April 1998 and May 2000, 1872 STD patients were screened for HIV infection. Data on demographics, medical history and sexual behaviour were collected at baseline. The overall HIV prevalence was 22.2%. HIV risk was associated with being divorced or widowed, less educated, living away from the family, having multiple sexual partners and initiation of sex at an early age. The risk behaviours in younger men were different to older men. Younger men were more likely to report early age of initiation of sex, having friends, acquaintances or commercial sex workers as their regular partners, having premarital sex and bisexual orientation. Young men were more educated and reported condom use more frequently compared with the older men. Similar high HIV prevalence among younger and older men highlights the need for focused targeted interventions aimed at adolescents and young men and also appropriate interventions for older men to reduce the risk of HIV and STD acquisition.  相似文献

Background

The HIV epidemic is growing among men who have sex with men (MSM) in China. Frequent HIV testing is associated with reduced HIV risk among MSM. However, little is known about factors associated with frequency of HIV testing in this population. We aimed to characterise sociodemographic characteristics and psychosocial factors associated with frequent HIV testing in HIV-negative MSM in Guangzhou, China.

Methods

We did this cross-sectional survey among MSM who were visiting a gay-friendly community clinic in Guangzhou between Sept 2 and Nov 24, 2016. Men were eligible if they were aged 18 years or more, self-identified biological males, and reported sexual contact with male partners in the past 12 months. Surveys were self-administered via a handheld electronic tablet. We collected sociodemographic characteristics and psychosocial measurements. HIV testing frequency was defined by three groups based on testing history: never tested, irregularly tested, or frequently tested. Irregularly tested MSM tested less than twice per year or tested less than every 6 months. Frequently tested MSM tested twice per year or tested more than once every 6 months. We compared sociodemographic and psychosocial measurements among MSM who never tested, irregularly tested, and frequently tested using χ2 testing or one-way ANOVA. Multinomial logistic regression and ordinal logistic regression were used to identify independent correlates that were associated with differences in frequency of HIV testing. Ethics approval was obtained from the ethics review boards of the Guangzhou Center for Disease Control and Prevention and the University of Pittsburgh.

Findings

495 MSM participated in this survey. Three participants refused to answer HIV testing history information and were excluded from this present analysis. Among the 492 MSM, 67 (13·6%) were never tested, 207 (42·1%) were tested irregularly, and 218 (44·3%) were tested frequently in the past 2 years. MSM who tested for HIV frequently were more likely to be older (p=0·001), reside in Guangzhou (p=0·016), and have higher monthly income (p=0·016). Compared with MSM who tested frequently, MSM who never tested were less likely to report that their sexual partner had ever received HIV tests (adjusted odds ratio 0·27; 95% CI 0·11–0·63) or that their good friends had ever received HIV tests (0·42; 0·22–0·78). Compared with MSM who tested frequently, those who never tested were also less likely to report having HIV-positive gay friend (0·39; 0·19–0·78) or ever discussing HIV with sexual partners (0·24; 0·12–0·47); they were more likely to report perceiving barriers to HIV testing (1·13; 1·03–1·24). Compared with MSM who tested frequently, those who tested irregularly were less likely to report having HIV-positive gay friends (0·65; 0·43–0·97) or to disclose their sexual orientation to non-gay friends (0·59; 0·38–0·92). Compared with MSM who tested frequently, those who teested irregularly reported greater barriers to HIV testing (1·07; 1·01–1·13) and higher internalised homophobia (1·06; 1·01–1·11). Ordinal logistic regression showed HIV testing frequency was associated with HIV testing by sexual partners and good friends, knowing gay friends who were HIV-positive, discussing HIV with sexual partners, disclosing sexual orientation to non-gay friends, barriers to HIV testing, and internalised homophobia.

Interpretation

Frequency of HIV testing could be improved among sexually active, HIV-negative MSM in Guangzhou, China. Enhanced interventions using HIV testing promotion via social networks, reducing structural barriers to HIV testing, and creating a gay-friendly environment could increase the frequency of HIV testing among MSM and increase the percentage of HIV-positive MSM receiving antiretroviral therapy, thus contributing to reducing HIV incidence in this population.
