Factors associated with help-seeking regarding sexual orientation concerns among Japanese gay and bisexual men: results from a cross-sectional survey.

OBJECTIVE: This study investigates Japanese gay and bisexual men's experiences of seeking help for emotional support from others regarding their sexual orientation concerns. It examines the relationship between their help-seeking and presence of gay and bisexual peers, duration between questioning their sexual orientation and accepting it, and experience of coming out to family members by multiple logistic regression analysis. RESULTS: We conducted a cross-sectional survey using a self-reported paper questionnaire. There were 360 valid responses. Eighty-two respondents (22.8%) had experience of help-seeking for emotional support, and this was associated with age, occupation, presence of gay/bisexual friends, and experience of coming out to family members about their sexual orientation. Respondents sought the most help from their male friends (70.0%), followed by female friends (25.0%), mothers (17.5%), and the Internet (16.3%). Even after controlling for age and occupation, experience of help-seeking for emotional support was higher among participants who had gay/bisexual friends when they were aware of their sexual orientation, took < 1 year from questioning to realizing their sexual orientation, and had come out to their family about their sexual orientation.

Barriers to cervical cancer screening faced by immigrant Muslim women: a systematic scoping review.

BACKGROUND: Uptake for cervical cancer screening (CCS) is extremely low among immigrant women, particularly Muslim women, because of barriers related to religious values, beliefs, and fatalism. This scoping review aimed to summarize and analyze the findings of previous studies regarding perceived barriers to CCS among Muslim immigrant women. METHODS: A search of electronic databases of peer-reviewed articles, including MEDLINE, CINAHL, PubMed, and Scopus was conducted. The following criteria were used for the selection of the articles: (a) the study population consisted of immigrant Muslim women, (b) CCS barriers were the main focus of the study, (c) the articles were original research articles, (d) the research was conducted within the last 10 years, and (d) the study was reported in English language. RESULTS: Barriers included sociodemographic factors, economic, language, cognitive, and emotional reactions. The healthcare system was classified as a community barrier, whereas culture and religion were categorized as social barriers. Beliefs that becoming ill and dying is the will of Allah and that health problems are a punishment from God were considered to be major barriers to CCS among immigrant Muslim women. CONCLUSION: Access to health service centers and CCS among Muslim immigrant women is challenging. Information dissemination by health care workers is needed to increase awareness of CCS and access to CCS service points among immigrant Muslim women. Physician recommendations to attend CCS also play an important role.

Practices and attitudes towards tuberculosis and latent tuberculosis infection screening in people living with HIV/AIDS among HIV physicians in Japan.

BACKGROUND: Tuberculosis (TB) continues to be the leading cause of death for people living with HIV/AIDS (PLHIV), and HIV is the strongest known risk factor for progression to active TB disease for persons with latent TB infection (LTBI). Screening for active TB and LTBI, and TB preventive therapy (TPT) is recommended, however, clinical practices regarding LTBI screening for HIV positive population have not been uniform, resulting in low rates of LTBI screening and TPT uptake, in both low and high TB-burden countries. We sought to explore the practices and attitudes towards TB and LTBI screening in PLHIV among HIV physicians in Japan. METHODS: We conducted a cross-sectional survey whereby an on-line questionnaire was administered to physicians who are currently, or have the experience of, providing care and treatment for PLHIV in Japan. RESULTS: The questionnaire was sent to a total of 83 physicians, of which 59 responded (response rate; 71.1%). 52.5% (31/59) conducted routine screening and 44.0% (26/59) conducted selectively screening for active TB among HIV/AIDS patients. As for LTBI, 54.2% (32/59) conducted routine screening and 35.6% (21/59) conducted selective screening for LTBI among PLHIV. "T-SPOT only" was the most frequently used method of screening (n = 33), followed by "QFT only" (n = 11). Criteria for LTBI screening included TB burden in the country of birth of the patient, previous contact with a TB patient, and CD4+ cell count. 83.1% (49/59) either "always" or "selectively" offered TPT to PLHIV diagnosed with LTBI, and among the 49 respondents who did provide TPT, 77.6% (38/49) chose 9-months isoniazid as their first choice. None chose regimen including rifampicin. CONCLUSIONS: Our study revealed that practices regarding TB and LTBI screening and treatment for PLHIV among HIV physicians were mixed and not necessarily in accordance with the various published guidelines. Building and disseminating scientific evidence that takes into consideration the local epidemiology of TB and HIV in Japan is urgently needed to assist physicians make decisions.

Epidemiology of coinfection with tuberculosis and HIV in Japan, 2012-2020.

This report examines the characteristics and treatment outcomes of patients with tuberculosis (TB) who are coinfected with HIV in Japan. Active TB cases newly notified to the Japan Tuberculosis Surveillance system during 2012-2020 were analysed retrospectively, during which 379 HIV-positive TB cases were reported. The proportion of HIV-positive cases among those with known HIV status increased, from 1.9% (62/3328) in 2012 to 3.5% (31/877) in 2020. The proportion of those with unknown HIV testing status was consistently high, at approximately 60%, and the proportion of those who did not undergo HIV testing increased significantly, from 21.6% (4601/21 283) in 2012 to 33.7% (4292/12 739) in 2020. The proportion of foreign-born cases more than tripled, from 14.5% (9/62) in 2012 to 45.2% (14/31) in 2020. The TB treatment success rate was higher among HIV-negative than HIV-positive cases (72.7% [3796/5222] versus 60.3% [88/146]), and among Japan-born than foreign-born HIV-positive patients (65.6% [61/93] versus 50.9% [27/53]), owing largely to the high rate of foreign-born cases transferring to care outside Japan. The increasing proportion of HIV positivity among TB cases tested for HIV in this study requires ongoing monitoring, especially among foreign-born persons. However, because the number of reported cases was small, and there was low completeness of reporting of HIV testing data in the TB surveillance system, these results should be interpreted with caution. Encouraging more complete data collection by training public health nurses who complete TB case interviews and ensuring ongoing monitoring of patients with TB/HIV coinfection are recommended.

Increasing access to HIV testing for men who have sex with men in Japan using digital vending machine technology.

Background: In Japan, most new HIV cases are reported amongst men who have sex with men (MSM); thus, there is an urgent need for further widespread testing of MSM. The use of Digital Vending Machines (DVM) in the UK offering HIV test kits targeting MSM show promising results. Digital Vending Machines could be useful to promote and increase the uptake of testing in Japan, although no studies have yet been conducted. We aimed to assess the acceptability and feasibility of distributing HIV test kits using DVMs exploring needs and concerns as well as preferred types of test kits and locations.Methods: Fifty-four individuals participated in workshops and meetings with a further 224 MSM answering a quantitative survey assessing HIV testing and prevention needs.Results: Amongst MSM who had never been tested, 73% showed willingness to purchase tests from DVMs. Responses were broadly positive about DVMs but there were concerns regarding being seen receiving test kits from the machines and linkage to confirmatory testing and appropriate care.Conclusions: Using DVMs to distribute HIV test kits in Japan was found to be both acceptable and feasible and may have the potential to increase access to testing for MSM. Future large-scale evaluation studies are required.

Associations Between Social Capital and HIV Risk-Taking Behaviors Among Men Who Have Sex with Men in Japan.

Social capital has been positively associated with reduced HIV risk. However, few studies have investigated if associations vary between men who have sex with men (MSM) or heterosexual alters (possessors of actual resources embedded within social capital networks) and HIV risk-taking behaviors. In a cross-sectional survey of 1564 MSM in Greater Tokyo, we investigated whether social capital ascertained from MSM or heterosexual alters influenced HIV risk-taking behaviors (i.e., consistent condom use and lifetime HIV testing). Multiple logistic regression revealed that MSM with high levels of social capital from heterosexual networks were twice as likely to report consistent condom use with casual male partners, while MSM who reported high levels of social capital from MSM networks were over twice as likely to have tested for HIV yet were half as likely to use condoms consistently with regular male partners. Associations between MSM, social capital, and HIV testing indicate the potential for integrating social capital enhancement programs into current HIV interventions.

Validation of mailed via postal service dried blood spot cards on commercially available HIV testing systems.

The demand for HIV testing using dried blood spots (DBS) has increased recently. However, DBS is not an approved sample for HIV testing in Japan. This study examined the validation of HIV testing with DBS, prepared at the laboratory or remotely and mailed via postal service to the laboratory. DBS were punched out from a 5.5 mm diameter circle on filter paper, then eluted with 600 µL of phosphate buffered saline overnight at 4℃, and analyzed by Lumipulse S HIVAg/Ab (LUM). The mean LUM count of DBS was 237.4-times diluted compared to titrated plasma. Repeated sample testing showed that although LUM count of DBS decreased slightly with increase in sample storage time (up to one month), it did not affect the result of HIV testing with DBS. Based on testing of 50 HIV+ confirmed cases and 50 HIV- persons, the estimated sensitivity was 98% (49/50) with a specificity of 100% when the cut-off value is 0.5. The single false negative case was a patient with undetectable viral load over the last 10 years, resulting in a decrease of antibody titer below the cut-off level. In conclusion, although DBS cannot completely replace plasma in HIV testing because the sensitivity was a little lower than that of plasma, it can be potentially useful for a screening test by self-finger-prick and postal service use. This will allow people to receive HIV testing without visiting public health centers.

Correlates of lifetime and past one-year HIV-testing experience among men who have sex with men in Japan.

This study aimed to examine correlates of lifetime and past-year HIV testing among men who have sex with men (MSM) in Japan. A unique, anonymous online self-report survey was conducted in 2015. A total of 776 participants completed the survey and answered questions on sociodemographic information, HIV-testing experience, history of syphilis, experience talking about HIV, recognition of AIDS-related community-based organization (CBO) materials, and sex behaviors. HIV-testing experience and related factors were assessed for two groups: regional cities and Tokyo and Osaka. A Poisson regression analysis revealed that higher lifetime HIV testing was associated with older age, previous syphilis diagnosis, and experience talking about HIV. Moreover, higher HIV testing in the past year was associated with experience talking about HIV with friends and recognition of HIV-related CBO materials. Increased dissemination of HIV-related information provided by CBOs may, therefore, be an effective prevention policy intervention targeted at Japanese MSM to promote regular testing and maintain their interest in HIV issues.

Survey of school nurses' experiences of providing counselling on sexual orientation to high school students in Japan.

OBJECTIVE: To ascertain the prevalence and correlated factors of providing consultation on sexual orientation and the characteristics of school nurses in high schools in Japan. METHODS: Participants were school nurses working in high schools in Aichi prefecture. Items investigated included background, experiences in providing counselling on sexual orientation, the availability of materials and resources for students, and learning experiences concerning how to handle sexual orientation concerns. We divided the respondents into two groups: one group who have provided counselling on sexual orientation before and one group with no such experience. Chi square tests were utilized to compare the responses between groups. RESULTS: Among the respondents, 38.9% (n = 140) had previous experience of providing counselling to students on sexual orientation. The group with experience of providing counselling is more likely to have 10-29 years of experience, to work at a senior high school, to be informed on notifications from the Ministry of Education, to have experience of learning how to provide counselling on sexual orientation, and to be aware of effective resources. CONCLUSION: In Japan, it is expected that the support needs related to LGBTI will become more obvious in the future and efforts to create an environment in which it is easy for young people to consult with school nurses or other support figures are necessary.

Factors associated with cervical cancer screening among young unmarried Japanese women: results from an internet-based survey.

BACKGROUND: The prevalence of cervical cancer among women aged 20-30 years has been increasing. A better understanding of the factors correlated with cervical cancer screening is vital to better identify suitable candidates and develop effective interventions. However, few studies have examined factors correlated with cervical cancer screening using a quantitative research design. Thus, this study aimed to assess the prevalence of and factors correlated with cervical cancer screening among unmarried and sexually active Japanese women aged 20-29 years. METHODS: Seven hundred Japanese women who responded to an internet-based cross-sectional survey conducted by a marketing research company in 2015 were enrolled. Associations between lifetime cervical cancer screening and demographic profile, sexual behavior, and psychosocial factors were assessed via univariate analysis. Variables indicating significance (P < 0.05) were used in the univariate analysis to determine adjusted odds ratios (AOR). RESULTS: Overall, 383 (54.7%) respondents underwent cervical cancer screening during their lifetime. Multiple regression analysis indicated that age, employment status, income, lifetime number of sex partners, human papillomavirus (HPV) vaccination, receipt of a free coupon for cervical cancer screening from the local government, perceived susceptibility and logistical barriers (cost/time), and confidence of receiving Pap testing from a male physician were significantly correlated with lifetime cervical cancer screening. Individuals aged 28-29 years (AOR = 1.86) and those with full-time employment (AOR = 3.30), income ≥ ¥ 4,000,000($35,000) (AOR = 1.60), > 5 lifetime sex partners (AOR = 1.97), HPV vaccination (AOR = 4.88), coupon from the local government (AOR = 3.14), higher perceived level of cervical cancer susceptibility (middle, AOR = 1.77; high, AOR = 3.23), lower perceived logistical barriers (middle, AOR = 0.55; high, AOR = 0.31), and higher confidence of receiving pap testing from a male physician (AOR = 2.66) were more likely to undergo cervical cancer screening. CONCLUSIONS: Women who were younger and unemployed and those with lower perceived cervical cancer susceptibility, higher perceived logistical barriers, and lower confidence of receiving Pap testing from a male physician were less likely to undergo lifetime cervical cancer screening. Thus, to increase the cervical cancer screening rate among young women, it may be effective to target younger unemployed women, provide interventions to increase perceived susceptibility, and recommend tests while considering psychosocial barriers.

Reporting quality of randomized controlled trials in patients with HIV on antiretroviral therapy: a systematic review.

BACKGROUND: To allow for correct evaluation of clinical trial results, readers require comprehensive, clear, and highly transparent information on the methodology used and the results obtained. This study aimed to evaluate the quality of reporting in articles on randomized controlled trials (RCTs) of antiretroviral therapy (ART) in the field of HIV/AIDS. METHODS: We searched for original articles on RCTs of ART developed in the field of HIV/AIDS in PubMed database by 5 April 2016. Searched articles were divided into three groups based on the revision year in which the Consolidated Standards of Reporting Trials (CONSORT) guidelines were published: Period 1 (1996-2001); Period 2 (2002-2010); and Period 3 (2011-2016). We evaluated the articles using the reporting rates of the 37 items in the CONSORT 2010 checklist, five items in the protocol deviation, and the three items in the ethics. RESULTS: Fifty-two articles were extracted and included in this study. Many of the reporting rates calculated using the CONSORT 2010 checklist showed a significantly increasing trend over the successive periods (65% in Period 1, 67% in Period 2, 79% in Period 3; p < 0.0001). The items with reporting rates < 50% were "the presence or absence of a protocol change and the reason for such a change," "randomization and blinding," and "where the full trial protocol can be accessed." Reporting rates of deviations were as low as < 30%, while the reporting rates for patient compliance were the highest (>80% in Period 3) among the five items. The reporting rates for obtaining informed consent and approval by the ethics committee or institutional review board were high (>88%), regardless of the time period assessed. CONCLUSION: In terms of representative RCT articles in the field of HIV/AIDS, the reporting rate of the items defined by CONSORT was approximately 70%, improving over the successive CONSORT statement revision periods.

Factors influencing behavioral intention to undergo Papanicolaou testing in early adulthood: Comparison of Japanese and Korean women.

In this study, we identified the factors influencing behavioral intention to undergo Papanicolaou testing among Japanese and Korean women in early adulthood. Their behavioral intentions were compared in this cross-sectional descriptive study. In total, 887 women (Japanese = 498, Korean = 389) aged 20-39 years participated in this study. Using a self-report questionnaire, knowledge, attitudes, subjective norm, perceived behavioral control, and behavioral intention were surveyed. There were significant differences between Japanese and Korean women's scores on all main variables. For Japanese women, all the variables moderately correlated with behavioral intention. In comparison, for Korean women, all independent variables, except for knowledge, moderately correlated with behavioral intention. Through a multiple regression analysis, age, undergoing Papanicolaou testing, attitudes, subjective norm, and perceived behavioral control were identified as significant predictors of behavioral intention among Japanese women. Among Korean women, job status, undergoing a Papanicolaou test, attitudes, subjective norm, and perceived behavioral control were demonstrated as significant predictors of behavioral intention. Health professionals should consider these factors to encourage Papanicolaou testing in women in early adulthood.

Everywhere in Japan: an international approach to working with commercial gay businesses in HIV prevention.

In the UK and Japan, there is concern regarding rising rates of annual new HIV infections among Men who have Sex with Men (MSM). Whilst in the UK and Europe, gay businesses are increasingly recognized as being important settings through which to deliver HIV prevention and health promotion interventions to target vulnerable populations; in Japan such settings-based approaches are relatively underdeveloped. This article draws on qualitative data from a recently completed study conducted to explore whether it is feasible, acceptable and desirable to build on the recent European Everywhere project for adaptation and implementation in Japan. A series of expert workshops were conducted in Tokyo, Nagoya and Osaka with intersectoral representatives from Japanese and UK non-governmental organizations (NGOs), gay businesses, universities and gay communities (n = 46). Further discussion groups and meetings were held with NGO members and researchers from the Japanese Ministry of Health, Labour and Welfare's Research Group on HIV Prevention Policy, Programme Implementation and Evaluation among MSM (n = 34). The results showed that it is desirable, feasible and acceptable to adapt and implement a Japanese version of Everywhere. Such a practical, policy-relevant, settings-based HIV prevention framework for gay businesses may help to facilitate the necessary scale up of prevention responses among MSM in Japan. Given the high degree of sexual mobility between countries in Asia, there is considerable potential for the Everywhere Project (or its Japanese variant) to be expanded and adapted to other countries within the Asia-Pacific region.

Impact of drinking and smoking habits on cerebrovascular disease risk among male employees.

OBJECTIVE: We aimed to analyze the impact of drinking and smoking behavior on the risk of developing cerebrovascular diseases among male employees aged 20-46 years. Twenty years of follow-up data of male employees enrolled in the DENSO Health Insurance Program were used for analyses. SUBJECTS AND METHODS: Of 29,048 male employees aged 20-46 years who were enrolled in the insurance program in 1994, 25,084 (86.4%) employees underwent annual health check-ups until 2003 without missing an appointment. Of these 25,084 employees, the data of 11,784 (40.6%) employees who self-reported drinking and smoking habits were used for analyses. The hazard ratio and 95% confidence intervals (CIs) for developing cerebrovascular disease in 2004-2013 were calculated in four risk groups categorized as per drinking and smoking behavior in the young group who were in their 20s and the middle-aged group who were in their 30s-40s in 1994. Based on their drinking behavior, participants were categorized into two groups: "not drinking or drinking sometimes" and "drinking every day." Based on their smoking behavior, participants were also categorized into two groups: "not smoking for 10 years" and "smoking for 10 years." RESULTS: A Cox's proportional hazard model revealed that after controlling for body mass index, systolic blood pressure, triglycerides, total cholesterol, fasting plasma glucose, and age, the hazard ratios for "smoking and drinking every day" were 3.82 (95% CI: 1.40-10.41) in the young group and 2.31 (95% CI: 1.27-4.17) in the middle-aged group. DISCUSSION: Male employees who had been drinking and smoking for 10 years had a higher risk of developing cerebrovascular diseases. To prevent cerebrovascular diseases among male employees, it may be effective to offer behavior change interventions for both drinking and smoking habits, regardless of the age group.

[A quantitative analysis of information-seeking behaviors regarding medical institutions with Spanish language support among South American Spanish-speaking migrants in Aichi Prefecture, Japan].

OBJECTIVES: This study aimed to explore the factors associated with information-seeking behaviors regarding medical institutions with Spanish language support among South American Spanish-speaking migrants living in Aichi Prefecture, Japan. METHODS: The survey targeted South American Spanish-speaking migrants aged 18 years and older currently residing in Aichi Prefecture who had lived in Japan for at least three months and who had previously seen a doctor in Japan. The questionnaire was written in Spanish and the survey was conducted from April to July, 2010. Wilson's information behavior model was used to study information-seeking behavior regarding medical institutions with Spanish language support among 245 respondents who completed the questionnaires (response rate: 58.9%). Experience seeking medical institutions with Spanish language support in the Tokai area was set as the dependent variable and a chi-square test was conducted to examine relationships with language support needs, recognition of and access to medical institutions with Spanish language support, living situation in Japan, and Japanese language skills. RESULTS: Among the 245 respondents, 106 were male (43.3%) and 139 were female (56.7%). The average age was 39.6±11.2 years old and 84.5% were Peruvian. The average length of residency in Japan was 11.0±5.7 years, and 34.3% of respondents had lived in Aichi for 5-9 years. A total of 165 respondents (67.3%) had searched for medical institutions with Spanish language support, while 80 (32.7%) had not. Information-seeking behavior regarding medical institutions with Spanish language support was associated with having previously experienced a need for Spanish language support when seeing doctors in Japan, finding and attending medical institutions with Spanish language support in the Tokai area, length of residency in Japan, Japanese language skills, and the language used in daily life. CONCLUSION: Experience in requiring Spanish support when sick or injured in Japan motivated respondents to seek medical institutions with Spanish language support. Communication difficulties in Japanese, speaking Spanish in daily life, and length of residency in Japan were relevant factors in their information-seeking behaviors. Respondents were likely to obtain information from family, friends, co-workers, and Spanish media, but not from public institutions that distribute Spanish material. Finding an effective way to disseminate health-related information was a fundamental health issue for South American Spanish-speaking migrants.

Lack of association between intact/deletion polymorphisms of the APOBEC3B gene and HIV-1 risk.

OBJECTIVE: The human APOBEC3 family of proteins potently restricts HIV-1 replication APOBEC3B, one of the family genes, is frequently deleted in human populations. Two previous studies reached inconsistent conclusions regarding the effects of APOBEC3B loss on HIV-1 acquisition and pathogenesis. Therefore, it was necessary to verify the effects of APOBEC3B on HIV-1 infection in vivo. METHODS: Intact (I) and deletion (D) polymorphisms of APOBEC3B were analyzed using PCR. The syphilis, HBV and HCV infection rates, as well as CD4(+) T cell counts and viral loads were compared among three APOBEC3B genotype groups (I/I, D/I, and D/D). HIV-1 replication kinetics was assayed in vitro using primary cells derived from PBMCs. RESULTS: A total of 248 HIV-1-infected Japanese men who have sex with men (MSM) patients and 207 uninfected Japanese MSM were enrolled in this study. The genotype analysis revealed no significant differences between the APOBEC3B genotype ratios of the infected and the uninfected cohorts (p = 0.66). In addition, HIV-1 disease progression parameters were not associated with the APOBEC3B genotype. Furthermore, the PBMCs from D/D and I/I subjects exhibited comparable HIV-1 susceptibility. CONCLUSION: Our analysis of a population-based matched cohort suggests that the antiviral mechanism of APOBEC3B plays only a negligible role in eliminating HIV-1 in vivo.

[Factors associated with HIV testing behavior and intention among men who have sex with men (MSM) in Japan].

OBJECTIVES: This study aimed to explore the factors associated with HIV testing behavior and intention among men who have sex with men (MSM) in Japan. METHODS: A self-administered survey was distributed to gay bar customers in Tokyo, Kanagawa, Osaka, Aichi, Fukuoka, and Okinawa from 2010 to early 2011. A total of 4,572 completed surveys were received by mail. Participants were divided into 3 groups based on HIV testing experience and intention: Group 1 consisted of those who had tested at least once in their lives; Group 2 consisted of those who had never tested but had an intention to test; and Group 3 was made up of those who had never tested and had no intention to test. Associations between groups were assessed using Chi-square goodness-of-fit test and multiple logistic regression. RESULTS: Among the 2,809 respondents reporting anal sex within the previous six months, 131 HIV-positive cases were excluded. Data were thus analyzed from 2,678 MSM; 61% (n=1,633) of participants reported having taken an HIV test at least once in their lives, 20.2% (n=541) reported never having tested but with an intention to test, and 18.8% (n=504) reported never having tested and had no intention to test in the future. Knowledge about HIV and testing, STI history, sexuality, academic background, knowing someone with HIV, and condom use in the past six months all correlated with HIV testing experience when compared between groups 1 and 2. Conversations on HIV/AIDS with friends, lifetime STI history, knowing someone with HIV, conversations on HIV/AIDS with a sexual partner, and older age were all correlated with intention of taking an HIV test when compared between groups 2 and 3. CONCLUSION: Among gay bar customers, those who know someone living with HIV and those who had conversations with friends about HIV/AIDS in the previous six months were more likely to take an HIV test compared to those who had never tested but had an intention to test. Thus, although knowledge about HIV and testing is important, knowing someone with HIV and having conversations about HIV/AIDS with friends are also important. Such factors should be considered in promoting the uptake of voluntary HIV testing among MSM.

Factors associated with unprotected anal intercourse and age among men who have sex with men who are gay bar customers in Osaka, Japan.

BACKGROUND: HIV infections among men who have sex with men (MSM) are increasing in Japan. METHOD: An anonymous self-administered questionnaire among clients of a gay bar in Osaka was used to analyse the relationship between age and unprotected anal sex (UAI). RESULTS: The highest rate of UAI was reported among those aged ≥45 (73.3%), followed by the ≤24 (60.7%), 25-34 (56.3%) and 35-44 (54.0%) age groups (P=0.01). In multivariate analysis, UAI was related to sex with six or more sexual partners among those aged ≤24 (adjusted odds ratio (AOR), 4.88; confidence interval (CI), 1.21-19.74), bisexual identity (AOR, 2.47; CI, 1.06-5.76) and drug use (AOR, 0.49; CI, 0.26-0.93 for no drug use) in the 25-34 age group, and no lifetime HIV testing in the 35-44 age group (AOR, 2.57; CI, 1.40-4.74). Condom purchasing and condom carrying were protective of UAI in 25-34, 35-44 and ≥45 age groups. CONCLUSION: Programs promoting condom use are needed for younger and older MSM.

[Condom use staging and correlations among gay and bisexual men. A questionnaire survey of Osaka gay bar customers].

OBJECTIVES: This study aimed to clarify stages of condom use among gay and bisexual men at gay bars in Osaka and to assess relationships between condom use stage and attitudes and norms regarding HIV prevention. METHODS: In this cross-sectional study, a self-administered survey was distributed to gay bar customers in Osaka in 2005. Completed surveys were received through the mail. Participants were divided into five groups based on condom use with regular and casual partners: pre-contemplation; contemplation; preparation; action; and maintenance. These five groups were merged into three groups: precontemplation; contemplation/preparation; and action/maintenance. Associations between these three groups of condom use stage and correlates were assessed. RESULTS: Among the 601 respondents (response rate, 44.9%), data from 546 men with lifetime sexual experience with men were used. Regarding stage distribution, the highest percentage of participants was in the pre-contemplation stage with a regular partner, and in the maintenance stage with casual partners. Activities of "MASH Osaka", a gay non-governmental organization, were widely recognized across all stages. The feeling of being unable to tell a partner to use a condom if the partner resisted condom use, being in a long-term relationship, difficulty using condoms when under the influence of drugs or alcohol, and self-efficacy all correlated with condom use stages. CONCLUSION: This study clarified condom use stages and correlations among gay and bisexual men at gay bars in Osaka. More research is needed to assess the reliability and validity of these scale items. Monitoring stage distributions and correlations with stages will be useful to evaluate HIV prevention activities.

Survey investigating homosexual behaviour among adult males used to estimate the prevalence of HIV and AIDS among men who have sex with men in Japan.

BACKGROUND: This study investigated the prevalence of male homosexual behaviour among adult men and of HIV and AIDS among men who have sex with men (MSM) and non-MSM in Japan. METHODS: An anonymous self-administered postal questionnaire, and national HIV and AIDS notifications. RESULTS: Same-sex sexual experience was reported by 2.0% of respondents. The prevalence of HIV and AIDS was 0.8818% among MSM and 0.0130% among non-MSM, indicating that HIV and AIDS are 68 times more prevalent among MSM. CONCLUSION: Our findings underestimate homosexual and HIV prevalence due to several methodological limitations. The high prevalence of HIV and AIDS among MSM in comparison with non-MSM indicates the urgent need to prioritise funding and programs targeting MSM in Japan.
