Objective: The proposal of this study is to determine the feasibility of using online social software to guide popular opinion leaders(POLs) among young students MSM (men who have sex with men, MSM) carrying out comprehensive AIDS prevention in young students MSM. Methods: From November to December 2019 in Tianjin, 22 POLs who had previously experienced AIDS prevention education and training foucus on life skills were recruited. Though snowball sampling method, 100 POLs partners (friends, sexual partners, classmates, etc) were invited into the study. From January to March 2020, regular posters will be sent through the WeChat platform to guide POL to intervene their partners/sexual partners. The questionnaire surveys were conducted before and after the intervention. Results: After the intervention, both the proportion of young students MSM had sex and with multiple sex partners decreased(χ2=12.12, 5.94, P<0.05). The comprehensive ability of AIDS prevention has improved significantly, the "National Eight Items" correct rate has risen from 90.0% to 99.0%(χ2=5.82, 7.56, P<0.05), and the "Youth Eight Items" correct rate has increased from 86.0% to 98.0%(P<0.01). Knowledge score increased from(11.08±1.89) to (11.84±1.27); Attitude score increased from (54.29±4.01) to (56.06±3.75), the behavior score increased from (52.12±4.78) to (55.08±4.25), skill score increased from (51.96±4.75) to (54.67±5.04), The comprehensive prevention ability score (percent) increased from (87.30±6.95) to (91.86±5.42)(t=-4.21, -3.51, -5.32, -5.16, -6.45, P<0.01). Conclusion Using Wechat platform to guide POL carrying out comprehensive AIDS prevention is effective for improving the comprehensive AIDS prevention ability of young students MSM.

Objective: To understand the characteristics of sexual partners and the influence of having multiple sexual partners on substance use among young male students man who have sex with men (MSM) in China, and to provide scientific basis for the prevention and control of HIV/AIDS among young MSM students. Methods: A mixed recruitment method of snowball sampling and respondent driven sampling was used to recruit young MSM students in Beijing and Tianjin, and a questionnaire survey was conducted among 220 participants from November to December 2019. Chi-square test and generalized linear model multi-factor Logistic regression were used to analyze the influencing factors of substance use before sexual behavior. Results: The average age of them was (22.39±2.57) years old, 84.5% of them were students, the average age of first sexual behavior was (18.83±2.45) years old, 44.1% of them had two or more sexual partners (including fixed sexual partners, temporary sexual partners and commercial sexual partners), 22.7% had more than one male fixed partner. After adjusting for age and education, having multiple sexual partners was risk factor for drinking alcohol before sex (aOR=2.97) or substance abuse (aOR=2.39). Having male temporary sexual partner was an risk factor in substance use before sexual behavior(OR=4.10). Conclusion The characteristics of sexual partners among young MSM students are complex, and the proportion of multiple sexual partners is high. Having fixed single sexual partner can reduce the risk of substance use before sexual behavior. AIDS prevention education for young MSM students should be further strengthened.

Objective: To preliminarily develop the Infectious Disease Prevention Health Literacy Scale for Chinese Middle School Students, as an important measuring tool for assessment of comprehensive abilities in infectious disease prevention of Chinese middle school students. Methods: The basic dimensional framework and item pool were established by literature review in the view of public health. Then Delphi method was used to modify the framework and item pool to scale 1.0. Panel discussion in middle school students was used to adjust the expression and structure of scale 1.0, turning it into scale 2.0. With the confirmation of theory experts subjects, the scale was preliminarily developed. Results: Literature review suggested that the basic dimension framework included five longitudinal dimensions and seven horizontal dimensions. According to Delphi method ( n =18), the Kendall s coefficient of concordance ( W ) of the scale was equal to 0.14 ( P <0.01), the average importance, proportion of full marks, coefficient of variation and weight coefficient of all dimensions and items met the inclusion criteria. According to panel discussion, the scale was finally adjusted into scale 2.0 with 53 items. Conclusion This study preliminarily established the Infectious Disease Prevention Health Literacy Scale for Chinese Middle School Students, which might be applied in both scientific research and practical use.

Objective: To understand the characteristics of KAP (knowledge, attitude and practice) related to the prevention of AIDS among young male MSM (man sex with man) in China, and to evaluate the comprehensive ability of AIDS prevention and associated factors to provide a scientific basis for the development of MSM AIDS prevention and control. Methods: From November to December 2019, sampling was recruited by using snowball sampling methods centered on Beijing and Tianjin. A cross-sectional survey of 222 young students MSM was conducted through an online questionnaire with information of general demographic characteristics, sexual behavior and HIV testing, psychological status and comprehensive ability to prevent AIDS. Results: Average score on comprehensive AIDS prevention knowledge was (87.64±6.41),with knowledge,attitude,and behavior score of (11.32±1.67)(54.87±3.36) and (52.18±4.30) respectively.The pass rate of knowledge, attitude, practice related to AIDS prevention were respectively 95.5%, 56.3%, and 27.0%. The separation rate of knowledge from belief was 42.8%, the separation rate of knowledge from behavior was 71.2%, and the separation rate of faith from information was 48.2%. Whether have received AIDS prevention education was related to knowledge qualification rate (P<0.01). Conclusion Current AIDS education is associated with the knowledge level of AIDS prevention among young MSM groups, but it is not enough to improve their attitudes and behaviors. The comprehensive ability of MSM in preventing AIDS among young students is still not optimistic. Intervention measures need to be further strengthened to improve the comprehensive ability of young students MSM group to prevent AIDS.

Objective: To understand comprehensive sexuality education knowledge among junior high school students in China, and to analyze relevant influencing factors to provide scientific basis for the implementation of school based sexuality education or comprehensive sexuality education in the future. Methods: By using convenient sampling method, a cross sectional survey was conducted among 4 545 students at grade 1 to grade 3 from junior middle schools in Beijing, Liaoning, Sichuan, Chongqing, Yunnan, Henan, using an online electronic questionnaire during September to October 2021. The questionnaire included general demographic information, subjective social status, sex education received at home and school, bullying, as well as knowledge, attitude, practice and needs towards comprehensive sexuality education. Results: The average score of the comprehensive sexuality education knowledge was (12.21±3.10) points, which was converted to (71.82±18.21) points based on the percentage based system. The scores varied by grade, sex and sexuality education setting, significantly higher in grade 3 students (12.69±2.99), girls (12.28±3.01) ( P < 0.01), and students who have received sex education at home (12.67±2.88) and students who received sex education at school (12.63±2.91), as well as those who had actively searched for sex information online had a higher score (12.71±2.94) ( t =35.10, 28.78, 10.55, P <0.01).Further analysis using multiple linear regression and Logistic regression, "whether you have received sex education at home" "whether you have received sex education at school" "whether you have searched the Internet actively" and "whether it is necessary to carry out comprehensive sex education" are still correlated with the score of comprehensive sex education knowledge; "self reported bullying" was still associated with "subjective social status" score, correct rate of question 2, and "shyness and inferiority toward the development of secondary sexual characteristics" ( P <0.01). Conclusion The current comprehensive sexuality education knowledge among junior high school students needs to be improved. The level of implementation of sexuality education in different settings varies, but the implementation of sexuality education in schools can help improve students comprehensive sexuality education knowledge level.

Objective: To understand the current situation regarding sex education in home and school settings in China, and to provide a scientific basis for more effective family and school sex education. Methods: Using a convenient sampling method, a crosssectional survey of students from grade 7 to grade 9 in Beijing, Liaoning, Sichuan, Chongqing, Yunnan and Henan was carried out from September to December 2021. The questionnaire covered general demographic information, sex education at home and school, and the status of comprehensive sexuality education. Finally, 4 109 valid questionnaires were collected. Results: A total of 760(18.50%) middle school students had not received any form of sex education, 923(22.46%) had only received sex education at school, 299(7.28%) had only received sex education at home, and 2 127 (51.76%) had received sex education at home and at school. The scores related to junior middle school students knowledge of comprehensive sexuality education was (12.43±2.89) points, the attitude score was (47.86±5.31) points, the behavior score was (40.44±5.18) points, and the comprehensive level score was (82.02±9.01) points. Junior middle school students who received sex education at home and in school had the highest comprehensive level of sex education( P <0.01). Junior middle school students who only received sex education at school had a higher comprehensive sexuality education knowledge level than those who only received sex education at home( P < 0.01 ). The level of comprehensive sexuality education behavior among junior middle school students who only received family sex education was significantly higher than among those who only received sex education at school( P <0.01). Conclusion Receiving sex education in both home and school settings can effectively improve the comprehensive sexuality education competency among junior middle school students. School based sex education should be further implemented in the future and family sex education should be encouraged.

Objective:To analyze the group heterogeneity of different types of self-management ability of patients with nonalcoholic fatty liver disease (NAFLD) through potential category analysis, and to explore the differences of nursing interventions among different types of people, so as to provide reference for intervention research.Methods:From March to August 2021, NAFLD patients undergoing physical examination and hospitalization in the First Affiliated Hospital of Xinjiang Medical University were selected as the research object by convenience sampling. The General Information Questionnaire, Health Promoting Lifestyle Profile-Ⅱ (HPLP-Ⅱ) and Self-management Behavior Scale for Patients with NAFLD were used to investigate the patients, and the height and weight of the patients were also measured. A total of 1 189 questionnaires were distributed and 1 124 valid questionnaires were recovered.Results:Self-management ability of NAFLD patients were divided into five types, including good self-management group (32.03%) , lack of self-management-medium level psychological cognition group (23.84%) , lack of health promoting behavior group (11.30%) , lack of disease-cognition-life management group (27.31%) , serious lack of self-management-medium level stress group (5.52%) . Taking the good self-management group as a reference, the results showed that age, marital status, occupation, education level, average monthly income, treatment methods, smoking, body mass index (BMI) , sleep quality, and concomitant diseases were the influencing factors that caused the potential category differences of self-management behavior in NAFLD patients, and the differences were statistically significant ( P<0.05) . Conclusions:Each potential category of NAFLD patients' self-management ability has specificity, which suggests that the formulation of nursing interventions for NAFLD patients in the future should be based on the heterogeneity of various types of groups, so as to improve the effectiveness of self-management intervention.

Objective: To identify the characteristics of social network and the association between ego-centric network and HIV status among young MSM Chinese students. Methods: The cross-sectional study was conducted in Chongqing, Tianjin, Harbin and Xi an city from April to December 2017 and from March to May 2018. A mixed recruitment method of snowball sampling and RDS approach was used to recruit participants who reported information on social network and received HIV test. The Multiple Regression Analysis method was used to for the analysis of association between ego-centric social network and HIV status of men who have sex with men (MSM) among young students. Results: The sample included 547 participants who nominated 1 088 social partners in total with average age of 13 to 60 years old. The MSM with different sexual orientation from their social members (aOR=0.38), embedded in a large network (aOR=0.63), with a high individual betweenness centrality (aOR=0.27) were at lower risk of HIV-positive status; while MSM who differed greatly in education level with their social members(aOR=1.60), existed in sexual networks(aOR=1.41), existed in the “risky networks” (aOR=1.88) , with high network density (aOR=1.91) and a high individual degree (aOR=4.10) had higher risk of HIV-positive status(P<0.05). Conclusion MSM with great difference in education level from social members, existed in sexual networks, with a large network density and a high degree were exposed to higher risk of HIV-positive status.
