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.

OBJECTIVETo explore the effective sexually transmitted infections (STI)/AIDS intervention strategies among female sex workers at the metropolis areas with low prevalence.

METHODSA comprehensive intervention was carried out among female sex workers in eight recreation establishments which have representative characters in Chaoyang district, and the effects of intervention was subsequently evaluated by a questionnaire from September 2005 to February 2006. The data were analyzed by SPSS11.5.

RESULTSThe study subjects aged 17-40 year old (25.22 +/- 5.81), and 203 (89. 82%) of them had high or middle school education background. 166 were unmarried, and 205 (90.70%) had no job, and 244 (99. 12%) subjects were migrants. After intervention, the correct answer rates for the knowledge of STI/ AIDS rose from 52.6% to 75.4% (chi2 = 22.701, P < 0.01); and the correct use of condom were higher than those of baseline, with the rise from 22.12% to 34.76% (chi2 = 8.14, P < 0.05).

CONCLUSIONThe STI/AIDS comprehensive intervention measures were effective and should be evaluated and generalized in the similar metropolis regions.

This paper examines the spread of venereal disease from the Opening of Korea to the early Japanese colonial period. It focuses on the formation and expansion of Japanese settlement in Korea, the influence of wars, and the state control of VD. The Opening of Korea made the foreign settlement, and Japanese licensed prostitution flourished in Japanese settlement. According to the First Annual Report of the Korean Government Hospital(1886) and Gyelimuisa(1887), VD patients occupied 18.3% of outpatients in Jejungwon hospital of Seoul and 8.9% of outpatients in Busan hospital. Directly after the Opening of Korea, Korean people's VD became lesser critical than Japanese people's VD. But the expansion of Japanese settlement and outbreak of two wars such as Sino-Japanese War and Russo-Japanese War made worse Korean people's VD. According to the Residency-General resources(1904-1909), syphilis patients was registered in 0.8~6.6%(average 3.6%). If it add to gonorrhea and chancroid patients which often could not be found out by the naked eyes, the number of VD patients will be increase. Ji Seok-yeong(1855-1935), the earliest smallpox vaccinarian in Korea, asserted the need of VD control. Though he warned men bought sex as well as prostitutes became the main culprit of VD diffusion, he supported licensed prostitution because of realistic possibility. The Great Han Empire(1897-1910) tried to control the lower grade whore, and gathered prostitutes in some area by police power. After Japanese annexation of Korea, while Japanese has gradually decreased in VD patients, Korean has gradually increased in VD patients.

OBJECTIVETo evaluate the effect and to explore the feasible model of 100% condom use programme (100%CUP) under existing policy and law milieu, so as to provide information for the adjustment of HIV/AIDS policy and intervention strategies.

METHODSInformation on knowledge, attitude and behavior of female sex workers (FSWs) in entertainment establishments were collected and followed by qualitative and quantitative analysis including: samples tested for Chlamydia; a repeated cross-investigation and the final evaluation on the effect of the programme.

RESULTSThe reported rate of condom use at the last sex activity with clients increased from 74.9% to 92.2% while the rate of sexually transmitted disease (STD) prevalence droped from 25.1% to 14.1% after three year's intervention program. The number of condoms distributed increased from 50,000 per quarter of a year in 2001 to over 100,000 in 2003. The rates of awareness on the knowledge of STD/AIDS prevention increased obviously.

CONCLUSIONThe 100%CUP was proved to be feasible and effective in the pilot site, and should be expanded in entertainment establishments.

Sexually transmitted diseases (STDs) are among the first ten causes of unpleasant diseases in young adult males in developing countries and the second major cause of unpleasant diseases in young adult women. Adolescents and young adults (15-24 years old) make up only 25% of the sexually active population, but represent almost 50% of all new acquired STDs. In general, STDs are epidemics and present an enormous health and economic consequences. An adequate screening for STDs should be done on a routine basis in every part of the world. Many STDs are asymptomatic and therefore can difficult to control. The purpose of reporting of STDs is to ensure that persons who are infected will be quickly diagnosed and appropriately treated to control the spread of infection and also so that partners are notified, tested and appropriately treated. It is estimated that reported cases of STDs represent only 50%-80% of reportable STD infections in the United States, reflecting limited screening and low disease reporting. High-risk sexual behavior is a highly contributive factor of this process as it often leads to teenage pregnancies and HIV/AIDS. One possible explanation for this behavior is that people do not have enough information about the transmission of STDs or ignore the precautions required for safe sex. Approximately 60% of new HIV infections worldwide occur in young people. The frequency of high-risk behaviors among youths may also be influenced by opportunity to engage in them, particularly the amount of time that they are unsupervised by adults. However, in diagnosing and treating these patients, we can effectively prevent the spread of HIV/AIDS. Individuals infected with STDs are 5-10 times more likely than uninfected individuals to acquire or transmit HIV through sexual contact. The breaking of the genital tract lining or skin creates a portal of entry for HIV and, hence, HIV-infected individuals with other STDs are more likely to shed HIV in their genital secretions. To date, the condom is the most effective method available for males for protection against STDs. It is important to control STDs, and prevention can be the key of this process. Prevention can be achieved through education of the population, identification of symptomatic and asymptomatic people, and effective diagnosis and treatment of these patients and their partners.

OBJECTIVEIn order to explore the features of discrimination against people with HIV/AIDS in rural areas, a community-based intervention was carried out in two pilot communities of X County of Shanxi Province from September 2002 to October 2003.

METHODSData were collected using qualitative methods (in-depth interview and focus group discussion) and anonymously structured questionnaires.

RESULTS(1) Severe discrimination against people infected with HIV/AIDS was revealed in the target communities. However, the response to HIV/AIDS was different in each community. (2) People were reluctant to disclose their HIV status or get tested for HIV, which endangered their sexual partners to contract HIV through unprotected sexual intercourses. (3) Attitudes towards people infected with HIV/AIDS varied. (4) Public education promoted a better understanding of HIV/AIDS which in turn improved community attitudes and behaviors towards people with HIV/AIDS.

CONCLUSIONHIV/AIDS-related discrimination undermines both individuals' and communities' responses to HIV/AIDS and may be a serious obstacle towards effective HIV/AIDS prevention and control.

OBJECTIVETo investigate the epidemiological characteristics of human papillomavirus (HPV) infection in men attending a sexually transmitted diseases (STD) clinic in Hangzhou area.

METHODSMale subjects (n=375) aged 18-70 years, attending the STD clinic were recruited. Urethral swabs were assessed for HPV DNA using polymerase chain reaction (PCR) with the consensus primers MY09/11. HPV genotypes of positive PCR products were determined by restriction fragment length polymorphisms and direct sequence analysis.

RESULTSOf the 375 swabs collected, 305 (81.3%) yielded sufficient DNA for the subsequent HPV analysis. Among the 305 subjects, the prevalence of HPV was 13.8%. Nononcogenic HPV types were found in 8.5% (26/305) of subjects, oncogenic types in 4.3% (13/305), and multiple types in 1.0% (3/305). The prevalence of HPV infection was higher in subjects from urban area than in those from rural area (P < 0.05). The prevalence was also higher in those who received fewer years of education (P < 0.05) and those who had more sex partners (P < 0.05).

CONCLUSIONSHPV infection among men at high risk is not uncommon. The detection rate of HPV DNA is significantly related to some sociodemographic factors, such as residence, educational level and the number of sex partners.

OBJECTIVE: To survey on men who have sex with men (MSM) population's sexual behaviors, condom-service condition, HIV related knowledge and other issues among MSM population at sexually transmitted disease (STD) clinics to understand the characteristics of behaviors and offer suggestions for effective health education and behavior intervention. METHODS: From January to December, 2009, we used anonymous questionnaires which involved in their mastery of demographic characteristics, sexual behavior, condom-service condition, HIV related knowledge, and so one, to investigate 200 MSM at 3 STD clinics of comprehensive hospital. RESULTS: The average age of informant was (26.7+/- 8.9) years and 121 individuals (62.6%) had confirmed with STD in recent one year. In the recent 6 months, the average number of homosexual partners was 9.2+/- 4.8 and 102 (52.8%) had heterosexual partners. In the sexual intercourse with homosexual, 123 individuals had anal intercourse (63.7 %) and 117 had oral intercourse (60.6%). In the sexual intercourse with heterosexual, 92 (90.2%) individuals had vaginal intercourse, 37 (36.2%) had anal intercourse, and 59 (57.8%) had oral sex behavior.There were a statistical difference between heterosexual and homosexual sex behaviors (P<0.01). The condom-using frequency had statistic difference in different sexual behaviors(χ²=188.396, P<0.001). There was no linear correlation between HIV related knowledge and condom-using condition in sexual behaviors except the heterosexual anal intercourse. CONCLUSION High AIDS knowledge mastery rate is found in our survey. The respondents get HIV/AIDS knowledge through various ways actively. There is no obvious relation between the mastery of HIV related knowledge and condom-using frequency. The ratio of non-protected sexual behaviors is high in heterosexuals. How to adopt effective methods for behavior intervention to MSM at STD clinic needs to be further studied.

Objective: To investigate the changes of proportion on both consistent condom use and syphilis infection among low-fee female sex workers aged 35 and above (LFSW), in order to provide evidence for targeted intervention strategies. Methods: A total of six cities-Liuzhou city and Pingnan couty of Guigang city of Guangxi Zhuang Autonomous Region, Jinghong city of Xishuangbanna Dai autonomous prefecture and Dali city of Dali Bai autonomous prefecture of Yunnan province, Zhangjiajie city and Jianghua Yao autonomous county of Yongzhou city Hunan province were involved in this study, with 60 eligible participants needed in each city, estimated through a pre-study. The first cross-sectional survey was completed from October 2012 to January 2013. Face-to-face questionnaire interview was carried out to collect information on socio-demography, work-related information and condom use situation. Blood was collected for syphilis testing. The second cross-sectional survey was carried out from June to September, 2015 under the same procedure. Results: A total of 371 and 403 eligible participants were included in the first and second survey, respectively. When comparing the two surveys, we noticed that the average age showed a slight change, from 42.4 years to 43.8 years old (t=3.537, P<0.001) and the average price for every commercial sex exchange increased from 36.8 RMB to 49.5 RMB (t=11.961, P<0.001). In the first survey, 46.9% (174/371) of the participants had more than two years of experience working as LFSW, compared to 61.3% (247/403) in the second survey (χ(2)=16.125, P<0.001). Also, 46.9% (174/371) of the participants consistently used condoms with clients in the past month in the first survey versus 64.3% (259/403) (χ(2)=23.641, P<0.001) in the second one. Rates of syphilis infection were found from 15.9% (59/371) in the first survey reduced to 7.2% (29/403) in the second survey (χ(2)=14.533, P<0.001). Conclusion: Compared with the first survey, the proportion of consistent condoms use showed an increase. Although the proportion of syphilis infection decreased in the second survey, the scope did not meet the criteria on syphilis, set by the government. Targeted intervention strategies on condom promotion and syphilis control should be implemented consistently in this population.

PURPOSE: With the continuous spread of the AIDS virus and other sexually transmitted diseases (STDs) throughout Asia, it has become imperative for HIV/AIDS prevention outreach programs to stress the need for using prophylactics as one form of protection. This is particularly true for commercial sex workers. This pilot study was conducted to investigate the rate of condom use among the commercial sex workers in Korea and reasons why they frequently do not wear condoms during sexual intercourse. METHODS: Fifty female commercial sex workers who worked in the Yong San area were recruited while outreach was performed and forty eight responses were analyzed due to two incomplete questionnaires. The data were collected on June 28, 2004 as part of an outreach program for condom use promotion. RESULTS: The subjects ranged in age from 21 to 45 years. Nearly half of the subjects (47.9%) did not consistently use condoms. The major reason for not using protection was clients'reluctances for using condoms. When condoms were used, the subjects preferred lubricant-rich and less painful condom during intercourse. CONCLUSION: Due to the inconsistent use of condoms, it is clear that many commercial sex workers and clients are susceptible to sexually transmitted diseases. Therefore, it is important to not only educate commercial sex workers, but also to educate their pimps and clientele about the importance of condom use. In general, it is recommended that practical strategies and a policy for condom use promotion be developed.
