OBJECTIVES: This study aims to investigate health disparities between lesbian, gay, and bisexual (LGB) adults and the general population in Korea, where there is low public acceptance of sexual minorities and a lack of research on the health of sexual minorities. METHODS: The research team conducted a nationwide survey of 2,335 Korean LGB adults in 2016. Using the dataset, we estimated the age-standardized prevalence ratios (SPRs) for poor self-rated health, musculoskeletal pain, depressive symptoms, suicidal behaviors, smoking, and hazardous drinking. We then compared the SPRs of the LGB adults and the general population which participated in three different nationally representative surveys in Korea. SPRs were estimated for each of the four groups (i.e., gay men, bisexual men, lesbians, and bisexual women). RESULTS: Korean LGB adults exhibited a statistically significantly higher prevalence of depressive symptoms, suicidal ideation and attempts, and musculoskeletal pain than the general population. Lesbian and bisexual women had a higher risk of poor self-rated health and smoking than the general women population, whereas gay and bisexual men showed no differences with the general men population. Higher prevalence of hazardous drinking was observed among lesbians, gay men, and bisexual women compared to the general population, but was not observed in bisexual men. CONCLUSIONS: The findings suggest that LGB adults have poorer health conditions compared to the general population in Korea. These results suggest that interventions are needed to address the health disparities of Korean LGB adults.

Sexual transmission became the major mode of HIV infection in this country and accounted for 95% of the newly diagnosed cases, 67% and 28% of heterosexual and male homosexual infections, respectively, in 2016. Heterosexual transmission was mostly reported in South-west while male homosexual transmission in North-east and major metropolitan areas. Elderly and young students became the two special groups of people with increased reported HIV cases in the past years, with major modes of transmission as both heterosexual and homosexual. HIV testing and treatment of all HIV infections have been national control strategies and implemented and have significantly reduced HIV sexual transmission among sero-discordant couples. However, about one-third HIV infections remained undiagnosed. HIV infection through sexual transmission will remain a challenge in the years to come.

BACKGROUND: In spite of active HIV/AIDS control and managements, UNAIDS estimate that 40 million people were living worldwide with HIV at the end of 2001. In Korea, The member of HIV- infected adults are continuously growing. For improvement of HIV screening and prevention, we analyzed over times the relationship between the changes in initial CD4+ T cell counts of newly HIV- diagnosed adults, sex, and exposure route. METHODS: We selected 1011 newly HIV-diagnosed adults whose initial CD4+ T cell count was determined within 6 months of HIV diagnosis between 1990 and June, 2002. Based on CD4+ T cell counts, the selected people were grouped into 4 as follows: <200 cells/mm3, 200-349 cells/mm3, 350-699 cells/mm3, and >700 cells/mm3. The relationship between initial CD4+ T cell counts, age, sex, and HIV risk category were studied by regression statistic methods. RESULTS: The median initial CD4+ T cell counts decreased over times (P<0.001). In each major group, over 50% of initial CD4+ T cell counts were below 350 cells/mm3. For homosexually infected adults, the median age did not statistically increase (P=0.062). However, in heterosexually infected adults, the median age increased throughout the time period examined (P<0.001) with an exception of female group (P=0.427). The multi-regression analyses revealed that older age (P<0.001) and male sex (P<0.001) were independently associated with lower initial CD4+ T cell counts, but not exposure group (P=0.483). For each year cohort of newly diagnosed adults, the median initial CD4+ T cell counts in subsequent years decreased until 1998 and then increased thereafter. CONCLUSION: These results show that a large proportion of HIV-infected adults are being diagnosed late in the course of HIV infection, particularly heterosexually infected male group. Therefore, we should continuously enforce screening, prevention and prompt diagnosis of high risk groups.

Respondent-driven sampling (RDS) is a method of sampling specifically for hidden populations, often applied to transgender women, female sex workers, men who have sex with men, and other groups that are difficult to identify and contact because of stigma and legal constraints. However, this method is gradually applied to the general population. With the continuous improvement of RDS, studies find that the network size of RDS samples can be weighted to estimate the overall situation and population size. This article summarizes the current application progress of RDS in population size estimation and provides ideas for the development of RDS and the use of RDS to carry out relevant research.

The purpose of this article was to get hold of adolescent's needs for sex knowledge and to reveal their understanding of sex. These results may be applied to the sex education and counselling for adolescent. The participants of study were 267 students (females, 144 ; males, 123) who were the first and second grade form 1 middle and 2 high schools. They were asked to describe 3 questions that they wanted to know or to learn about sex. Their questions about sex were total 779(girls, subtotal 456, mean 3.2: boys, subtotal 323, mean, 2.6). These questions categorized to 9 items by content analysis. The items were 'sexual drive, behavior and tendency(229, 29.4%)', 'anatomy and physiology of reproductive system(140, 18.0%)', 'reproduction(131, 16.8%)', 'concept of sex(31, 4.0%)', 'acquaintance between the other sexes(17, 2.2%)', and 'the others(9, 1.2%)' in order of frequency. The most frequent item that the student want to know or learn about sex was 'sexual drive, behavior and tendency' except girls of sophomore in middle school. There were several features in participants' needs for sex knowledge as respects of the understanding of sex-biological sex, gender, and sexuality. The prominent feature in knowledge need of biological sex was that the participants had the interests according to their biological sex. They had the negative attitude to the phenomenons(ex, menstruation and pregnancy, phimosiectomy, etc) that they experienced or would experience due to their biological sex. A part of them asked the questions based the misconceptions and used the slangs or 'XX', ect. to name the male or female genitalia. The male students wanted to know the female genitalia. The participants' understanding of gender reflected the sexism of our society, but they didn't accept and had doubts about the dual, hierarchical structure of that. The students, especially female seemed to be powerless to the harms of the sexual violence. Girls had much interest in their appearances and complained to our sexual culture that women comforted and served men. The participants had the dual perspective that the sexuality as respects of physiologic phenomenon was considered as natural but that as related to heterosexuals was as negative. And they deemed that men's sexual drive was stronger than women's and was difficult or was not able to be inhibited. They had much interests in homosexuality but reflected the negative attitude to that in our society. Adolescent felt wonder why the expressions of sexuality of adult were permitted but theirs were not. Lastly, a part of boys substituted querying the sexuality of animals for asking that of human. Maybe it was because of the embarrassment to talk about human's sexuality directly. The teenaged participants understood that the sex had not only the biological meanings but also the sociocultural meanings. They regarded the sex as natural and wanted to know it, but they had conceptions that it was difficult and embarrass to talk about it openly and directly.

OBJECTIVETo investigate gay identity status of men who have sex with men(MSM) in Xinjiang, and analyze its association with sexual behaviors.

METHODSFrom May to August in 2013, an anonymous questionnaire survey with convenience sampling was conducted among MSM in Urumqi, Kashgar, Aksu and Yining cities of Xinjiang. Those who were ≥ 16 years of age and claimed to have male-to-male sex behaviors were eligible for the survey. A total of 1 467 participants were recruited. Chi square analysis was performed for examining the association between ego-identity, social-identity and relevant sexual behaviors. Selected variables associated with ego-identity, social-identity in the univariate analysis were subsequently assessed in a multivariate analysis using logistic regression.

RESULTSThe MSM with positive ego-identity accounted for 44.7% (656/1 467), and positive social-identity accounted for 29.1% (427/1 467). For ego-identity, Uyghur MSM were less positive than Han MSM (OR (95%CI) was 0.43 (0.32-0.58) ) ; those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.61 (0.47-0.80) );and homosexuals were more positive than bisexuals (OR (95%CI) was 1.98 (1.50-2.61) ). For social-identity, Hui MSM were less positive than Han MSM (OR (95%CI) was 0.61 (0.42-0.88) ); those whose education level was higher than college were less positive than those with junior high education (OR (95%CI) was 0.60 (0.40-0.89) ); famers/herdsmen were more positive than students (OR (95%CI) was 4.17 (2.13-8.17) ); the divorced/widowed were more positive than the singles (OR (95%CI) was 2.40 (1.34-4.29) ); those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.59 (0.44-0.81) ). Among the MSM with negative ego-identity and negative social-identity, the proportion of planning to get married with women was 66.8% (267/400) and 76.5% (306/400), respectively, which were higher than those with positive ego-identity (33.2% (133/400)) and positive social-identity (23.5% (94/400)) ; their proportion of intending to have offspring was 62.0% (287/463) and 73.4% (340/463), respectively, which were higher than those with positive ego-identity and social-identity (38.0% (176/463), 26.6% (123/463)) (χ(2) = 39.61 and 7.90, respectively, both P values were <0.05). Among the MSM with negative social-identity, the proportion of looking for male sexual partners in toilets or parks was 18.1% (188/1 040), in bathhouse or sauna was 17.3% (180/1 040), and through internet was 82.0% (853/1 040), which were higher than those with positive social-identity (8.9% (38/427), 9.8% (42/427) and 61.6% (263/427)) (χ(2) = 66.78, P < 0.01).

CONCLUSIONIn 2013, the gay identity of MSM in Xinjiang was relatively poor, and the factors associated with it included ethnicity, occupation, marital status and education level. The MSM with negative identity tended to involve in risk sexual behaviors, and had increased risk of HIV infection.

OBJECTIVETo understand the HIV epidemic and its correlation among the community-based drug users in Dongguan, Guangdong province.

METHODSIn 2008, 13 drug users were identified as seeds in Dongguan. Respondent driven sampling was applied to recruit community-based drug users. A structured questionnaire was used for a face to face interview. Intravenous blood samples were collected for the measurement of HIV, HCV and syphilis antibodies. RDS analysis tool (RDSAT) was applied for adjusting the estimates and bivariate analysis.

RESULTSA total of 303 drug users were recruited within 15 weeks and 300 blood samples were collected. After RDSAT adjustment, the prevalence rates of HIV, HCV and syphilis were 14.7% (95%CI: 6.1% - 25.4%), 63.2% (95%CI: 55.7% - 71.7%), and 4.7% (95%CI: 1.8% - 8.2%) respectively. The HIV prevalence rates among those who were HCV seropositive, migration, younger than 26 years at their first drug use, and ever shared needles or syringes were 22.9% (95%CI: 10.8% - 37.0%), 26.9% (95% CI: 11.4% - 44.9%), 19.9% (95%CI: 8.3% - 35.7%), and 29.1% (95%CI: 12.3% - 45.1%) respectively. The proportions of the drug users who were enrolled at methadone maintenance treatment (MMT) of local residency, migration were 20.9% (95%CI: 4.1% - 44.6%), 2.3% (95%CI: 0.0% - 7.0%) respectively.

CONCLUSIONThe HIV epidemic among the community-based drug users in Dongguan is serious. Drug users who are HCV seropositive, migration, younger than 26 years at their first drug use, and ever shared needles or syringes are more likely to be HIV seropositive.
