Objective: In this study,respondent-driven sampling survey(RDS)was used to investigate the AIDS-related knowledge,attitude and behavior characteristics of MSM in Hebei Province.And statistics inferred the population of AIDS and syphilis prevalence,and the overall size of the population estimates.For the future to further develop effective STD and AIDS prevention and control policies and measures to provide scientific basis and reasonable recommendations.Methods: In April and December 2016,the survey was conducted at the Tsukiguo City Center for Disease Control and Prevention(CHD)voluntary counseling and testing(VCT).The survey sites included two survey rooms /consultation rooms,one blood collection room and six stable The person in charge.The recruiting method was carried out by means of Respondent Driven Sampling(RDS),and standardized training and pre-experiment were carried out on the basis of qualitative research and preparation.Selected 11 different types of seeds,began to recruit four coupons per person to promote the network recruitment at the same time the implementation of pyramid-type coding records.Standardized questionnaires and blood tests for each person included in the screening criteria: Informed consent-Screening registration(to prevent duplication of investigation)-Pre-test counseling-Questionnaires-Blood detection-issuance of recruiting cards and rewards-informed after detection.The main contents of the questionnaire include demographic basic information,AIDS knowledge status,AIDS attitude and AIDS behavior characteristics,blood tests to extract 5ml venous blood for HIV and syphilis antibody detection.After the data were collected,the data were collected by EpiData3.1 software and edited according to the RDSAT standard format,andusing Net-draw 2.0 software to investigate the visualization of sample social networks.The RDSAT7.1 software was used to deduce the prevalence rate of the data under different factors and 95% confidence interval estimation.The chi-square test and logistic regression analysis between different variables were performed with SPSS20.0 software to determine the influencing factors and the effective regression equation.Results: In this study,559 questionnaires were sent to the qualified participants,and 559 were collected.The recovery rate was 100%.A total of1586 coupons were received,559 received and 35.2% effective.A total of 11 different types of seeds were recruited,of which one from the school did not sprout the new recruitment object,the relevant indicators in the 7th floor began to gradually balance,the longest recruitment layer continued to the 11 th floor.1 Demographic characteristics: survey showed that 21 to 30 age group was 343 people 59.0%,married with 105 people 23.1%,73.1% for the majority of unmarried,the overall population education is relatively high,the proportion of professional distribution of students can not be overlooked25.2%(95% CI: 20.3~31.3),the economic level of 3001~4000 yuan mainly26.8%.2 Awareness of AIDS knowledge: new national standard awareness rate of answer card awareness rate of 447 people 85.5%,of which 224 were 39.6%(95% CI: 33.7~47.1)were 8 points all right,there are 1 people all wrong zero.Only 306 people 55.0% know the significance of AIDS test results can be inferred three months before the non-infected HIV,only 280 50.7%(95% CI:44.1~56.9)know that CD4 is the main reference value of the severity of AIDS infection.3 Attitude content: only 83 people 11.5%(95% CI: 8.0~15.8)will take the initiative to tell their parents,175 people often detect 31.1%(95% CI:25.7~36.9),279 people think that uncomfortable is the main reason for the use of condoms Accounting for 50.9%(95% CI: 44.7~57.7).Most people are pessimistic about self-abandonment,44.9%(95% CI: 28.2~66.6)who aretrying to correct themselves if they have positive sunshine.Of the sexual orientation but can not change.4 Behavioral characteristics: the same sex is the result of many reasons,the pursuit of curiosity stimulus reached 273 people 49.3%(95% CI:43.8~56.5)accounted for the largest proportion,The first homosexual sexual identity is 59.6%(95% CI: 54.1~67.0).The most common way to find homosexual couples is 42.6%(95% CI: 34.5~47.9)for homosexual software(Blude and Zank).The main role of homosexual behavior in their own 0.5mostly 207 people 39.9%(95% CI: 33.4~45.5).There were 23 people with same-sex commercial behavior 4.3%(95% CI: 2.1~7.4).222 people took rush stimulants 34.6%(95% CI: 28.0~40.2).People who use OTC caps are 31 people 4.5%(95% CI: 2.6 to 7.0).5 Serum test results and stratification analysis: the prevalence and confidence interval of Syphilis was 14.1%(95% CI: 10.4~18.6).The positive rate of HIV infection and confidence interval were 8.0%(95% CI:5.1~11.7).The prevalence of HIV prevalence was stratified by RDSAT 7.1software,and the overall positive prevalence and confidence intervals were obtained for each layer.There are differences in the prevalence of HIV among different factors.The results of the analysis showed that marital status,condom use,number of sexual partners,the use of zero capsules,and TP infection were significant(P <0.05).The regression equation was obtained as follows: Y =0.66X1+0.56X2+0.39X3-1.28X4+0.78X5-2.71.6 Analysis of influencing factors: only the educational level was significant about HIV knowledge(P<0.05).The effective regression equation was Y= 0.31X1+1.36.The final economic status,the first homosexual sex age,the common way to find the same sex,the number of the same sex,and the same-sex behavior were significant,The effective regression equation is:Y=-0.21X1+0.55X2-0.22X3+ 0.12X4-0.36X5+0.31,about the condom use.Finally,the four factors of homosexual partner,homosexual sex,homosexual sexual behavior and peer education were the influencing factors.The effective regression equation was Y =-0.63X1-0.34X2+0.64X3+1.73X4+3.1.Conclusions:1 The epidemic rate of AIDS among the MSM population in Shijiazhuang City has been declining and declining in recent years,and the MSM population is less than 2% of the population.MSM population characteristics exist knowledge-attitude-behavior in the use of condoms on the separation of knowledge,and the use of stimulants consistent with the situation.2 The prevalence of HIV infection is different under different infection factors,the final marital status,the use of condom use,the number of sexual partners,the use of zero capsules,TP infection is a risk factor for HIV infection,the number of companions and the use of zero-numbered capsules is a risk factor for syphilis infection.3 The MSM population under different infection factors has different characteristics in AIDS awareness,condom use and stimulant use.Actively explore a comprehensive new model of HIV / AIDS prevention and control,to guide the positive and healthy sexual orientation of sex,to achieve the safety of infection is not afraid of the best results.
