Survey on epidemiology and habits of seeking medical services of 109 patients with sexual transmitted diseases (STDs) (62 male and 4 female) at National Dematology Hospital shows that prevalence is higher among youth (20-39); state workers 33.9%; mostly in urban areas (68.8%); people had high school education and more (77.4%). Most women had married (60.9%); while most men have been single (89.2%). Male patients often contracted STDs due to having sexual activities with partners or sex workers (81.6%). Female patient contracted STDs mainly through husband (85%). Most STD patients seek for medical service within the next days (77.9%) or months. Those who came to hospitals/dermatology institute/dermatology centre was 53.2% and those who came to private clinics and chemistry for self treatment is 31.1%.

Trichomoniasis is an important sexually transmitted disease that is associated with increased perinatal morbidity and increased HIV transmission. Infection with Trichomonas vaginalis also results in local urogenital tract symptoms. Standard teaching is that trichomoniasis is an important cause of vaginitis in women, but that male sexual partners experience little or no morbidity. It is worth-while to summarize critical findings in a series of articles. The prevalence of Trichomonas vaginalis in men represents an important consideration in the differential diagnosis of urethritis.

This study aims to compare the prevalence of sexually transmitted infections (STIs) with semen quality in men from couples with primary and secondary infertility. Semen samples were collected from 133 men who requested fertility evaluation. Seminal tract infection with Ureaplasma spp. (UU), Mycoplasma hominis (MH), Mycoplasma genitalium (MG), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and herpes simplex virus-2 (HSV-2) was assessed by PCR-based diagnostic assays. Among all patients, the prevalence of STIs was higher in men from couples with primary infertility than that in men from couples with secondary infertility (39.7% vs 21.7%, P = 0.03). The prevalence of UU was 28.8% and 13.3% in men from couples with primary and secondary infertility, respectively. Men from couples with primary infertility were more likely to be positive for UU than men from couples with secondary infertility (P = 0.04). Regarding the UU subtype, the prevalence of Ureaplasma urealyticum (Uuu) and Ureaplasma parvum (Uup; including Uup1, Uup3, Uup6, and Uup14) did not differ between the two groups. No associations between the prevalence rates of MH, MG, and CT were found in men from either infertility group. A lower sperm concentration was associated with STI pathogen positivity in men with primary infertility according to the crude model (P = 0.04). The crude and adjusted models showed that semen volume (both P = 0.03) and semen leukocyte count (both P = 0.02) were independently associated with secondary infertility. These findings suggest the importance of classifying the type of infertility during routine diagnosis of seminal tract infections.

Joinpoint regression was used to analyze the trend of syphilis and gonorrhea incidence rate among 10-19 year old adolescents in Liaoning Province from 2006 to 2020. The syphilis and gonorrhea data in Liaoning Province were reported in the infectious disease monitoring system of China's disease prevention and control information system. From 2006 to 2020, a total of 7 721 cases of syphilis in 10-19 year old adolescents were reported in Liaoning Province, with an incidence rate about 0.90/100 000-22.13/100 000. The incidence rate of syphilis in women was higher than that in men. Adolescents infected with stage Ⅰ and stageⅡ syphilis accounted for 72.6%. There were 2 726 patients with gonorrhea, with an incidence rate about 1.29/100 000-10.74/100 000. The incidence rate of gonorrhea in men was higher than that in women. Joinpoint regression model analysis showed that the incidence of syphilis generally took 2012 as the inflection point. From 2006 to 2012, the average annual growth rate of syphilis incidence rate among adolescents was 67.30% (P<0.001). The average annual growth rate of syphilis incidence rate in adolescents from 2012 to 2020 was -0.02% (P=0.994).The overall incidence of gonorrhea incidence rate took 2015 as the inflection point. From 2006 to 2015, the average annual growth rate of juvenile gonorrhea incidence rate was 23.95% (P<0.001). The average annual growth rate of gonorrhea incidence rate in adolescents from 2015 to 2020 was 4.06% (P=0.492). Overall, from 2006 to 2020, the incidence rate of syphilis and gonorrhea among 10-19 year old adolescents in Liaoning Province increased slowly. The primary and secondary prevention strategies were significantly effective in reducing the risk of sexually transmitted diseases.

PURPOSE: This study was done to identify and compare factors associated with intention to receive Human Papillomavirus (HPV) vaccine between male and female undergraduate students. METHODS: In the fall of 2010, 479 students responded to self-administered questionnaires about their intention to receive HPV vaccine, HPV knowledges, HPV related involvements and optimistic bias, subject's characteristics including opinion about HPV vaccine. Mann-Whitney U test, uni-variate and multi-variate logistic regression were used for data analysis with SPSS/WIN. RESULTS: Intention to receive vaccine were 22.0% of men and 25.0% of women. There were significantly different in HPV knowledge (Z=-2.74, p=.006), optimistic bias (Z=-4.60, p<.001), vaccine is necessary for women (Z=-4,30, p<.001), vaccine is necessary for men (Z=-4.37, p<.001), vaccine is necessary if only symptom exist (Z=-4.52, p<.001), but there were not different in intention to receive vaccine, involvement between men and women. Concern about vaccine safety (OR=3.19, 95% CI 1.63~6.23) was determinant of intention to receive HPV vaccine for men. CONCLUSION: This study showed gender differences in HPV knowledge, HPV related optimistic bias and opinion about HPV vaccine, which would be assessed and well managed in tailored HPV education for enhancing HPV vaccine acceptance.

OBJECTIVETo analyze sexual behavior characteristics and sexually transmitted diseases such as AIDS infections in man who have sex with men (MSM) of Beijing Chaoyang district.

METHODSThrough selecting 10 MSM as seed in Chaoyang district of the existing education member companion in its main activity place, using snowball sampling to select 1008 people that 16 years old or above, nearly a year had sex with male in Chaoyang to conduct an investigation.Questionnaires were used to investigate the general conditions, characteristics of sexual behaviors, condom usage, AIDS knowledge awareness and sexually transmitted diseases history. Each participant was asked to exsanguinated 5 ml peripheral blood for applying ELISA for HIV, syphilis helicoids detection and HIV positive samples confirm test. Using χ(2) test on the statistical analysis of the data.

RESULTSIn the 1008 MSM, most of them were with the age of 20 - 29 years old (66.6%, 671/1008), giving priority to unmarried (79.1%, 797/1008), college degree and above culture during accounted for 43.3% (436/1008), 56.2% (566/1008) had both male and female sexual partners; the rate of temporary sexual partners who were one-night stand objects or friends or guest was 72.2% (226/313). The forever condom utilization rate was 29.0% (170/587) in MSM who had both male and female sexual partners, lower than that who had both male and female sexual partners (47.2%, 345/731). That the study objects of HIV infection who can use condom correctly rate was 3.6% (16/442), and that who never or occasionally used condom rate was 8.5% (24/228). AIDS, gonorrhea and other sexually transmitted diseases (to give priority to the acuteness wet wart) infection rates were 4.8% (6/124), 10.5% (13/124) and 8.9% (11/124) in those who had the history of group sex, and that was 5.9% (52/884), 1.9% (17/884) and 2.3% (20/884) in those who without the history of group sex. The research object's gonorrhea and other sexually transmitted diseases (to give priority to the acuteness wet wart) who provided commercial sex service infection rates were 7.7% (9/117) and 6.8% (8/117), significantly higher than those who did not provide a commercial sex service object of study subject (2.4% (21/891)and 2.6% (23/891)).

CONCLUSIONHIV infection is high among MSM population. Types and identification of sexual partners, and condom use are associated with HIV and STD infection.

INTRODUCTIONThis is a review of the epidemiology and trends of sexually transmitted infections (STIs) in Singapore from 1994 to 2003.

MATERIALS AND METHODSData collated for both notifiable and non-notifiable STIs from 1994 to 2003 were analysed. This data consisted of STI notifications from medical practitioners in Singapore as well as from the Department of STI Control clinic itself.

RESULTSThere was a decline in the overall STI incidence in Singapore in the first half of the last decade from 215 cases per 100,000 population (7,200 cases) in 1994 to 162 cases per 100,000 population (6,318 cases) in 1999, followed by an increasing trend in the number of acute STIs (both bacterial and viral) over the past 5 years to 195 cases per 100,000 population (8,175 cases) in 2003 (P <0.001). The incidence of HIV has risen sharply over the last decade whilst that of other viral STIs has not decreased. Singaporeans are becoming sexually active at a younger age, with casual partners constituting the main primary contacts.

CONCLUSIONSAlthough there has been a significant decline in the overall incidence of STIs in Singapore over the last decade, a rise in acute STIs over the last 5 years has resulted in the need to identify the causal factors, and to intensify existing as well as develop new STI/HIV prevention programmes for the general population and certain core groups.

OBJECTIVETo study sexual behavioral characteristics, infection status of HIV and sexually transmitted infections (STDs) among women who have sex with women (WSW) in Beijing.

METHODSA total of 150 WSWs were recruited by snowball sampling in several main types of activity sites of WSW (including NGOs, salons, bars, etc.) in Beijing during September 2010 to April 2011. Information on demographic factors, sexual behavioral characteristics, infection status of STDs, and use of medical care were collected by questionnaire investigation. Serum samples, vaginal and cervical swabs were taken for each subject to test HIV, hepatitis B (HBV), hepatitis C (HCV), syphilis, herpes simplex virus (HSV), neisseria gonorrhoeae, chlamydia trachoma, bacterial vaginosis, trichomonas vaginalis and mycotic vaginitis.

RESULTSThe age range of the subjects was from 19 to 46 years old. Approximately 82.67% (124/150) of them aged 20 to 29 years old, and 54.00% (81/150) were unmarried. Approximately 76.67% (115/150) had an education level of college degree or above, and 70.67% (106/150) were migrants. Approximately 66.66% (100/150) of the subjects considered themselves as homosexual, 28.00% (42/150) as bisexual. The age at first homosexual sex ranged from 11 to 30 years old. The median of number of female sex partners in last 1 year was 1, and 33.78% (50/148) of the subjects had 2 or more female sex partners. Approximately 20.27% (30/148) of the subjects applied sex instruments, of which 66.67% (20/30) never or seldom used condoms. Hand-clitoris and hand-vagina contacts were the main types of woman-to-woman sex, accounting for 91.22% (135/148). 12.00% (18/150) of the subjects had sex with men during last year. Among them, 50.00% (9/18) used condoms at last heterosexual sex, and 66.67% (12/18) never or seldom used condoms at last heterosexual sex in past 1 year. One subject provided paid sex service for men, and used condoms every time. In the past one year, 45.33% (68/150) of the subjects had symptoms of STDs, but only 36.76% (25/68) of them sought medical care. The infection rate of STDs was 34.67% (52/150). The infection rates of NG and GV were both 16.11% (24/149), and those of mycotic vaginitis, chlamydia trachoma, and TV were 8.72% (13/149), 4.03% (6/149), and 0.67% (1/150), respectively. The numbers of subjects tested positive for HBV, HCV, and syphilis were all 1. No subjects were found HIV positive or HSV-2 positive.

CONCLUSIONMultiple sexual partners and heterosexual sex behavior were common among WSW in Beijing. More than 1/3 of the subjects were infected with STD.

OBJECTIVETo understand the infected status of human immunodeficiency virus (HIV), sexually transmitted disease (STD) and relative risk behaviors of men who have sex with men (MSM) in Beijing.

METHODSRespondent-driven sampling (RDS) was adopted to recruit target population and to conduct behavior and serological studies among MSM. RDSAT 5.5 was used to analyze data.

RESULTSAmong 427 MSM, the age distribution was as follows: below 30 and less than 35 were 65.4% and 81.0% respectively. 69.2% (95% CI: 63.9-75.5) of them had 12 years or less of education. 73.3% (95% CI: 66.7-79.8) of them were non-Beijing registered residents. The urban and rural registered residents almost accounted for half of all the recruits. HIV positive rate was 4.6% (95% CI: 2.2-7.6) while 56.3% (95% CI: 50.9-62.5) of them reported having had bisexual sex preference. Only 14.8% (95% CI: 10.8-19.6) of them had ever had HIV test, while 22.8% (95% CI: 18.7-27.8) reported ever having had STDs. 55.3% (95% CI: 49.3-61.9) and 55.1% (95% CI: 48.7-61.3) of them had unprotected insert and receptive anal sex over the last 6 months.

CONCLUSIONData from the HIV positive rate showed that there was a trend of increase among MSM in Beijing which called for urgent care to them.

OBJECTIVETo investigate the current situation of the sexual transmission of HIV in Dehong prefecture, analyze the influential factors, and provide support for drafting pertinent preventive interventions in the future.

METHODSWe had analyzed the data of case report from 2005 to 2007, and the prostitutes surveillance data from 2003 to 2007. A special survey was conducted from October 26 to November 7, 2007. Totally 685 people including prostitutes, the clients of prostitutes, people who were HIV positive and their partners, key insiders were interviewed in order to better understand the influential factors related to sexual transmission of HIV.

RESULTSAmong 1636 cases reported from January 1 to September 20, 2007, 52% were infected through sexual transmission. Among 586 cases infected through sexual transmission, 40.6% had commercial sexual behavior and 28.6% had unmarried sexual behavior. And the average rate of condom use was below 30%. The prostitutes' surveillance data from 2003 to 2007 showed that the HIV positive rate in prostitutes was 3.3% - 5.5%. The rate of condom use in the last month was 29.4% - 84.4% during commercial sexual activity, but it was 9.5% - 34.8% with fixed sexual partners. Although the rate of HIV and AIDS-related knowledge among prostitutes was 95.0%, there were still many misunderstanding regarding certain aspects of HIV and AIDS awareness.

CONCLUSIONSexual transmission has become one of the main transmission routes of HIV in Dehong prefecture. The main factors involved in the sexual transmission of HIV in Dehong prefecture might include the wide spreading of sexual services, cohabitation among unmarried couples, having multiple partners, casual sexual behavior, and the low rate of condom use.
