Objective To understand the prevalence of and factors associated with unprotected anal intercourse(UAI)among men who have sex with men(MSM)in Beijing.Methods Five hundred MSM were recruited for a survey using Respondent Driven Sampling (RDS)method, from September to October in 2009. A computer-assisted, interviewer-administered questionnaire was used to gather information including demographics, sexual behaviors and condom use social norms(a scaled number). Variables were evaluated by using RDSAT and SAS software.Results Mean age of the participants was 30.6 years, with 96.0% of them as Han ethnicity and68.5% having had at least high school or higher education level. 72.8% of them were unmarried, with 61.7% of them identified themselves as homosexual, 61.2% had ＞ 1 male partners in the past six months, and the prevalence of UAI was 42.0%. Significant bivariate predictors of UAI would include condom use social norms score, role for anal sex with male sex partner, number of male sexual partners in the past 6 months and amount of alcohol consumed. In multivariable analysis, UAI was associated with a higher condom use social norms score(AOR= 1.2, 95%CI: 1.1-1.3), receptive anal intercourse(AOR=2.0, 95%CI: 1.3-3.2)and drinking alcohol more than 3 times per month in the past 12 months(AOR=1.6, 95%CI: 1.1-2.5). Conclusion The prevalence of UAI was high in the MSM community in Beijing, suggesting that efforts should be targeting on how to make the condom use a social norm and being promoted.

OBJECTIVE To understand the cognitive status and influencing factors of hepatitis B prevention knowledge among primary and secondary school students of Kaifeng City in 2018, so as to provide a good guarantee for improving students’ health awareness and disease prevention knowledge. METHODS A questionnaire survey was conducted among primary and secondary school students in Kaifeng from May to July 2018 by stratified sampling and cluster sampling. The questionnaire was provided by China Liver Prevention Foundation. Questionnaire survey mainly analyzed in-depth knowledge about hepatitis B among primary and secondary school students in Kaifeng City, the score of hepatitis B related knowledge among primary and secondary school students of different ages, and the influencing factors of knowledge about hepatitis B were analyzed. RESULTS The awareness of hepatitis B related knowledge among primary and secondary school students in Kaifeng was generally low, with a total awareness rate of 47.84%. The awareness rate of knowing hepatitis B was 82.91%, which was the highest. Secondly, the awareness rate of timely vaccination of hepatitis B vaccine after birth was 73.73%. The lowest awareness rate was that there was no specific drug for hepatitis B at present, which was 13.82%. Different characteristics of primary and secondary school students had different scores of hepatitis B knowledge. Ethnic group, age, educational level and household registration had an impact on the score of hepatitis B related knowledge (P<0.05), while gender had no effect on the score of hepatitis B related knowledge (P>0.05). Multivariate linear regression analysis was used to analyze the influencing factors of knowledge about hepatitis B. It found that age and household registration were the factors influencing the score of knowledge about hepatitis B among primary and secondary school students. CONCLUSION It was very important for the prevention and treatment of hepatitis B to strengthen the propaganda and education of hepatitis B prevention knowledge among primary and secondary school students, to do a good job in propaganda of hepatitis B transmission channels and non-transmission channels, and to find a more scientific and reasonable health education mode.     

Serostatus disclosure and associated factors among people living with HIV/AIDS （PLWHA） in Liuzhou City,China

Introduction HIV serostatus disclosure has become an entry criterion for prevention of sexual partners spread, so we aimed to examine the prevalence of disclosure and associated factors among people living with HIV/ AIDS （PLWHA） in Liuzhou City, Guangxi Zhuang Autonomous Region, southern China. Methods The PLWHA with marital or regular sexual relationship were eligible for our study, and a self-de- signed questionnaire was assigned to all the convenient- ly sampled participants. Determinants of disclosure were analyzed using chi-square test and binary Logistic regression. Results A total of 425 PLWHA were included in the present study. Two hundred and forty-five （57.6%） disclosed their HIV-positive status to their spouses/reg- ular sexual partners, while 180（42.4% ） did not. A- mong the 245 informed spouses/regular sexual part- ners, 236 （96. 3 % ） had received the HIV testing and the positive rate was 50.4%. While among the non-informed spouses/regular sexual partners, 63 （35.0%） had received the HIV testing and the positive rate was 3.2%. Binary Logistic regression analysis indicated that age, area, monthly income, HIV/AIDS related knowledge and antiretroviral therapy （ART） were in- dependently associated with HIV serostatus disclosure. Conclusions The disclosure rate was low in this study. As to its influencing factors, it is necessary to provide comprehensive disclosure consulting among PLWHA living in urban, the elderly or high monthly income and emphasize the propaganda on HIV/AIDS related knowledge, expand coverage for antiretroviral therapy, so as to provide scientific reference for promoting HIV disclosure and reducing the HIV incidence of spouses/ regular sexual partners among PLWHA.     

Analysis of TORCH screening results of 330 115 reproductive-age females who underwent pre-pregnancy health examination in Shenzhen北大核心CSCD

Objective To analyze the results of TORCH screening for reproductive-age females who underwent pre-pregnancy health examination in Shenzhen to guide scientific pregnancy preparation. Methods Cross-sectional study was performed on the TORCH screening results of 330 115 reproductive-age females who participated in free pre-pregnancy health examination in Shenzhen from January, 2013 to December, 2019. The ?2 test was used to analyze the differences of TORCH screening results among reproductive-age females in different years, administrative regions and demographic characteristics. Results The overall positive rates of screening for rubella virus (RV)- IgG, cytomegalovirus (CMV)-IgG, CMV-IgM, toxoplasma gondii (TOX)-IgG and TOX-IgM among reproductive-age females in Shenzhen were 85.54% (282 377/330 115), 96.36% (318 088/330 115), 0.31% (1009/330 115), 3.12% (10 292/330 115) and 0.64% (2114/330 115), respectively. Compared with 2013 to 2016, the average positive rates of RV-IgG and CMV-IgG among reproductive-age females in Shenzhen increased (P=0.003, P<0.001), while the average positive rates of TOX-IgG and TOX-IgM decreased from 2017 to 2019 (P<0.001). There were statistically significant differences in the positive rates of the five antibodies among different administrative regions (all P<0.001). Except for the differences in the positive rates of CMV-IgM and TOX-IgM among women of different ages, there were statistically significant differences in the positive rates of these five antibodies among reproductive-age females with other demographic characteristics (all P<0.05). There were statistical differences in the positive rates of TORCH antibodies among women with different demographic characteristics in different years. Conclusion Compared with 2013 to 2016, the positive rates of RV-IgG and CMV-IgG in reproductive-age females in Shenzhen from 2017 to 2019 were on the rise, while the positive rates of TOX-IgG and TOX-IgM were on the decline. The positive rates of these five antibodies were different among different administrative regions and among reproductive-age females with different demographic characteristics, which suggested that plans should be made according to local conditions and different objects in order to strengthen the awareness of eugenics and reduce the risk of congenital intrauterine infection with TORCH of the fetus during the propaganda and education of eugenics. © 2020 Chinese Medical Journals Publishing House Co.Ltd.

环境和遗传因素与广东前列腺癌关系的病例对照研究

Objective To explore the etiologic relationship of prostate cancer and environmental and genetic polymorphism in southern China. Methods A hospital-based and 1 : 1 matched case-control study was conducted. A total of 142 matched pains of subjects were investigated in this study. The blood samples were collected from 85 cases of prostate cancer and 82 controls of other diseases after informing consent. The CYPIAI ,CYPI7 and AR genes were analyzed by using the method of PCR, PCR-RFLP. The data were analyzed with conditional logistic regression model. Results An increased risk of prostate cancer development was observed with the early first spermatorrbea (age<18) (OR=2. 90,95% CI: 1.76-4. 80), early first sexual intercourse (age≤ 24) (OR=2. 38,95% CI: 1.14 -4. 96), frequent sexual intercourse before 35 year old (OR=1.80,95% CI: 1.19 -2. 70), family history of cancer (OR=2. 70,95% CI: 1.31 -5.58), more intake of pork (OR=2. 27,95% CI: 1.38 -3.70). Factors in lowing the risks were the fruit intake and drinking of green tea by OR value at 0. 25 (95% CI: 0. 08 -0. 75) and 0. 52 (95% CI:0. 28 -0. 96) respectively. CYP17 A1/A2 and CYP17 A2/A2 genotypes were related with a high risk of prostate cancer and OR values of 1.78 (95% CI: 0. 70 -4. 53) and 2. 57 (95% CI: 0. 91 -7. 25) respectively. Study also showed that there was an interaction between CYP17 polymorphisms and early first spermatorrbea and family cancer history related to the risk of prostate cancer with OR value at 13.35 (95%CI: 1.58 -113.00) and 4.01 (95% CI: 1.22 -13.17) respectively. Conclusion Sexual intercourse, dietary intake and family cancer history should be related to prostate cancer occurrence. CYP17 polymorphism might be associated with a high risk of prostate cancer. It suggests that there are multiple environmental and genetic factors to the prostate cancer.
