RESUMO
A survey was conducted to analyze the HIV testing status and related influencing factors of male sexually transmitted diseases(STD) patients attending 18 county-level hospitals in Shandong Province from July 2015 to August 2016. The HIV detection rate of 1 570 subjects was 77.58% (1 218/1 570), and the HIV-antibody positive rate was 0.99% (12/1 218). Compared with general hospitals patients, urinary and anorectal patients, non-sexual patients, and patients with negative attitudes toward HIV testing, patients were more likely to be tested for HIV from specialized hospitals (OR=3.74, 95%CI:2.53-5.54), the skin and venereal section (OR=1.92, 95%CI: 1.31-2.79), the STD group (OR=2.02, 95%CI: 1.34-3.03) and patients with positive attitude (OR=15.20, 95%CI:10.74-21.52).
RESUMO
Objective@#To understand the survival status of AIDS patients after initiation of antiretroviral treatment (ART) in Shandong province during 2003 to 2017, and to determine the factors associated with survival status.@*Methods@#A retrospective cohort study was conducted among AIDS patients initially received antiretroviral therapy from 2003 to 2017. The epidemiological characteristics of the subjects were described, and life tables were used to estimate the survival rates, the influencing factors were analyzed by Cox regression model.@*Results@#A total of 9 813 cases were enrolled in this study, of the subjects, the median age was 34.9±11.0 years. The median of baseline CD4+ T lymphocyte count was 300.0(P25-P75: 163.0, 428.0)cells/μl, and 83.2% of them were at clinical stage Ⅰ (World Health Organization, WHO). The cumulative survival rates were 97.7%, 96.7%, 95.8% and 93.7%, 1, 3, 5, and 10 years after the initiation of ART respectively. Multivariate Cox regression model analysis showed that the risk of the mortality among those infected through homosexual behavior was 38% lower than that of patients infected via blood or other routes, and HR was 0.62 (95%CI: 0.43-0.89). Higher education level had lower mortality risk(the mortality risk of those with university degree or above was lower, compared to those with primary and lower cultural level, HR=0.41, 95%CI: 0.26-0.65). At baseline, AIDS patients at clinical stage Ⅰ(WHO) had lower mortality risk than those who were at clinical stageⅡ, Ⅲ, and Ⅳ(WHO). Lower baseline CD4+ T lymphocyte count had higher mortality risk.@*Conclusions@#Survival rate was higher after initial antiretroviral therapy among AIDS patients in Shandong province. CD4+ T lymphocyte count level, WHO clinical stage, and presence or absence of clinical symptoms at baseline are the main factors influencing the survival time of AIDS patients after ART.
RESUMO
Objective@#This study aimed to examine the demographic characteristics, HIV related knowledge and behavior, correlates of bisexual behavior and status of HIV infection among men who have sex with men only (MSMO) and men who have sex with both men and women (MSMW) in Shandong province.@*Methods@#According to the requirements from "National HIV/AIDS sentinel surveillance program" , a cross-sectional survey was conducted to collect information on demographics, sexual and drug use behaviors, and HIV-related services among MSM in nine sentinel surveillance sites from April to July in 2018. Blood samples were drawn for serological tests on both HIV and syphilis antibodies.@*Results@#A total of 3 474 participants were included in this study. Related information on these participants would include: average age as (31.66±9.01) years; 35.06% (1 218) married or cohabiting with a woman, 50.52% (1 755) had college or higher education, 80.11% (2 783) self-identified as gays and 14.22% (494) self-identified as bisexual men,16.87% (586) ever having sex with woman in the past 6 months, 10.51% (365) ever using drugs. HIV and syphilis prevalence rates were 2.99% (104/3 474) and 2.76%(96/3 474). Through multivariable logistic models, MSMW were more likely to be ≥35 years of age, local residents, self-identified as heterosexual/bisexual/uncertain, ever having commercial sex with man but less likely to consistently use condoms in the past 6 months, less using internet/dating software to find male sex partners and less using drugs. There was no significant differences noticed in the following areas: number of sexual partners in the last week, condom use in the last six months with commercial sex partners, with HIV or syphilis infection and self-reported history of STD in the past year between MSMO and MSMW (P>0.05). HIV-infected MSM were more likely to have the following features, ≥45 years of age, non-local residents, finding male sex partners from the bothhouses, park/toilets or from the internet/dating software, also less likely to consistently use condoms in the past 6 months, using drugs or with syphilis infection.@*Conclusions@#High prevalence of bisexual behavior as well as higher risk of HIV infection were noticed among MSM in Shandong province. It is important to strengthen related surveillance and effective intervention programs for MSM with different characteristics in Shandong province.
RESUMO
Objective To understand the survival status and influencing factors for HIV/AIDS patients on highly active anti-retroviral therapy (HAART) in Shandong province.Methods Both Kaplan-Meier (K-M) method and cumulative incidence function (CIF) were used to calculate the cumulative incidence of AIDS-related death respectively,and Fine-Gray model was used to identify the influencing factors related to survival time.Results Through K-M method,a higher AIDS-related cumulated death rate than the CIF,was estimated.Among all the HIV/AIDS patients who initiated HAART from 2003 to 2015 in Shandong,5 593 of them met the inclusion criteria.The cumulative incidence rate for AIDS-related death was 3.08％ in 1 year,4.21％ in 3 years,5.37％ in 5 years,and 7.59％ in 10 years respectively by CIF.Results from the F-G analysis showed that HIV/AIDS patients who were on HAART,the ones who had college degree or above (HR=0.40,95％CI:0.24-0.65) were less likely to die of AIDS-associated diseases.However,HIV/AIDS patients who were on HAART and living in the western areas of Shandong (HR=1.33,95％CI:1.01-1.89),diagnosed by medical institutions (HR=1.39,95％CI:1.06-1.80),started to receive care ≥1 year after diagnosis (HR=2.02,95％CI:1.30-3.15),their CD,cell count less than 200 cells/μl (HR=3.41,95％CI:2.59-4.59) at the time of diagnosis,with NVP in antiviral treatment (ART) regime (HR=1.36,95％CI:1.03-1.88),at Ⅲ/Ⅳ clinical stages (HR=2.61,95％CI:1.94-3.53) and CD4 cell count less than 350 cells/μl (HR=5.48,95％CI:2.32-12.72) at initiation of HAART ect.,were more likely to die of AIDS-associated diseases.Conclusions With the existence of competing risks,the cumulative incidence rate for AIDS-related death was overestimated by K-M,suggesting that competing risk models should be used in the survival analysis.Measures as early diagnoses followed by timely care and early HAART could end up with the reduction of AIDS-related death.

RESUMO
Objective@#To describe the confirmation process and long-term follow-up results of 1 case of HIV with long term progression.@*Methods@#The subject was a HIV infected man aged 27 years old. The first HIV antibody positive was detected by ELISA in August 7th, 2013. Close contacts were identified as 3 homosexual partners who had been contacted before infection and the first sexual partner had been unable to get in touch. Adopting the first epidemiological survey questionnaire of AIDS comprehensive prevention and control information system in China, the investigators conducted face-to-face surveys on the general demographic characteristics and behavioral characteristics of the subject. After the first ELISA test result was positive, 4 rapid detections of colloid selenium, ELISA, western-blot, CD4+T and viral load test were followed up (August 14th, 21st, 30th and September 16th, 2013). Long term follow-up was performed to detect CD4+T and viral load to observe the progress of the case after the diagnosis of infection.@*Results@#The duration of sexual behavior was from 2011 to 2012 between the subject and his 1st sexual partner. During the study, repeated HIV antibody ELISA test results were negative. Sexual behavior maintained from January to April 2013 between the subject and his 2nd partner and the last one unprotected homosexual acts took place in April 2013. After the traceability survey, the 2nd sexual partner was an AIDS patient who had antiretroviral therapy in the anti HIV treatment module of AIDS comprehensive prevention information system. The subject and his 3rd partner maintained their sexual behavior from May to October 2013. The two ELISA tests of the 3rd partner were negative. Because of the need for hospital operation in August 7, 2013, the subject was tested for HIV antibody by ELISA and the result was positive while western blot test showed that the HIV-1 antibody was not confirmed (band type was gp160/gp120/p24). In the subsequent follow-up, 4 rapid detections of colloid selenium, ELISA and western-blot were conducted and all the results were positive (western-blot band type was gp160/gp120/gp41/p24/p17). Results of continuous follow-up for 5 years showed that the first four CD4+T cell counts were as follows: 520, 616, 834, 879. The following 22 CD4+T counts sustained at a high level and the median was 895 cells/μl. A total of 5 follow-up visits were conducted to detect viral load exceeding 1 000 copies/ml and the remaining 19 test results were lower than 1 000 copies/ml except that no viral load was detected in 2 follow-up visits. The result of homology analysis showed that the HIV types of the case and its 2nd sexual partner were all HIV-1 CRF_01AE. The similarity of gag region gene was 97.5%. So we inferred that the 2nd sexual partner was its source of infection, and the case was infected at the end of April 2013 with the last unprotected homosexual behavior.@*Conclusion@#The infected person was found to be an early HIV infection. Continuous follow-up test results indicated that the case belonged to a HIV long-term nonprogressor.
RESUMO
Objective@#To analyze the epidemic features of male HIV-infected and AIDS patients by sexual transmission in Shandong Province.@*Methods@#Data on HIV-infected people and AIDS patients (HIV/AIDS) were derived from HIV/AIDS Comprehensive Response Information Management System. To analysis the epidemiological data of male HIV/AIDS by sexual transmission reported in Shandong Province from 1997 to 2016.@*Results@#A total of 8 584 HIV/AIDS were reported by heterosexual transmission or homosexual transmission from 2007 to 2016. 2 421 cases were reported by heterosexual transmission and 6 163 cases were reported by homosexual transmission. Among cases infected by heterosexual transmission. The average age of cases infected by heterosexual transmission was (38.13±12.39) and (31.62±10.22) among cases who infected by homosexual transmission (t=24.95, P<0.001). 84 cases were reported by homosexual transmission and 138 cases by heterosexual transmission from 2007 to 2008, and 6 079 cases were reported by homosexual transmission and 2 283 cases by heterosexual transmission from 2009 to 2016. A total of 770 cases were dead after reported. Among the dead cases, 337 cases were infected by homosexual transmission and 433 cases by heterosexual transmission (χ2=328.21, P<0.001). 61.4% of the dead cases by heterosexual transmission were no longer than 6 months after reported and 54.3% in homosexual transmission (χ2=3.96, P=0.047).@*Conclusion@#Homosexual transmission has been the main transmission of HIV/AIDS in Shandong Province. Epidemiological features and social demographic characteristics of each sexual transmission were different. As part of HIV cases developed to death in 6 months.
RESUMO
Objective To analyze the epidemiological characteristics,dynamic trend of development and related influencing factors of hepatitis C in Shandong,China,2007-2016,also to provide epidemiological evidence for prevention and control of HCV.Methods National surveillance data of hepatitis C from 2007 to 2016 in Shandong was used,with distribution and clustering map of hepatitis C drawn at the county level.Panel Poisson regression was used to explore the influencing factors of hepatitis C at the city level.Results The incidence of hepatitis C in Shandong increased from 1.49/100 000 in 2007 to 4.72/100 000 in 2016,with the high incidence mainly clustered in the urban regions in Jinan,Zibo,Weihai et al.and surrounding vicinities.Majority of the cases were young adults,with 53.16％ (14 711/27 671) of them being farmers.Results from the Multiple panel Poisson regression analysis indicated that factors as:population density (aIRR=1.07,95％ CI:1.05-1.10),number of hospital per hundred thousand people shared (aIRR=1.16,95％CI:1.08-1.24),expenditure of medical fee in rural (aIRR=1.21,95％CI:1.08-1.37) and the proportion of the tertiary industry (aIRR=1.08,95％ CI:1.07-1.09) were all correlated to the incidence of hepatitis C.Conclusions The incidence of hepatitis C had been increasing rapidly in recent years,in Shandong.Prevention and control of HCV should focus on high risk population.In addition,rural,especially in areas with lower economics provision should be under more attentions,so as to find more concealed cases for early treatment.
RESUMO
Objective To understand the characteristics of new-type drug consumption,sexual behaviors and the prevalence of HIV infection among male new-type drug users in Qingdao,Shandong province.Methods A cross sectional survey was conducted from 2015 to 2016.Participants were recruited from MSM community-based organizations (CBO) and general community through snowball method,relying on volunteers and male peer educators who were on new-type drugs themselves.Face-to-face interview was carried to collect information on drug use and sexual behaviors.Blood samples were collected to test HIV,syphilis and HCV antibodies.Urine samples were collected to test the evidence of new-type drugs.Qualitative variables and quantitative variables were analyzed using Chi-square test/Fisher's exact test and Student's t-test respectively.Multivariate logistic regression was used to analyze related factors of binary variables.Results A total of 1 034 new-type drug users were recruited,including 431 (41.7％) MSM population and 603 (58.3％) who were not MSM.Compared with the the group of people who were not MSM,people in the the MSM group were younger,unmarried and with higher level of education.The proportion of methamphetamine users were 49.7％ (214/431) and 100.0％ (603/603) among the groups of MSM or not MSM,respectively.People in the MSM group,66.8％ (288/431) used 5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT,"foxy") in the last six months.However,none from the not-MSM group ever used 5-MeO-DIPT.In the last six months,proportions of sharing new-type drugs with more than two people in the MSM or not groups were 87.9％ (379/431) and 97.7％ (588/602),respectively (x2=39.84,P＜0.01).Proportions of unprotected sexual behavior among the MSM or not groups were 47.5％ (285/600) and 7.4％ (32/430) respectively (x2=190.10,P＜0.01).The proportions of ‘group sex’ after using drugs among the two groups were 78.1％ (335/429) and 5.5％ (33/600) respectively (x2=573.73,P＜0.01).The prevalence rates of HIV,syphilis and HCV antibody positive among the MSM or not groups were 2.1％ and 0.2％,3.3％ and 6.3％,0.0％ and 0.3％,respectively.Conclusion The prevalence of sharing new-type drugs with more than two people was high among male new-type drug users in Qingdao city.Male new-type-drug-users who were MSM,presented both high prevalence of group sex and HIV infection,and with less condom use.Intervention measures towards this sub-population should be strengthened.

RESUMO
Objective@#To survey the prevalence of drug resistant HIV-1 in Shandong province in 2013-2015.@*Methods@#WHO truncated sequential sampling technique was adopted by using 77 and 53 samples of newly diagnosed as HIV-1 positive and aged 16-25 years in Shandong province in 2013 and 2015. RNA was prepared and HIV-1 pol region was amplified by RT-PCR and nested PCR. Pol genetic mutation associated with drug resistance was analyzed.@*Results@#The success rates for sequence acquisition of the survey were 100% (77/77) and 94% (50/53) in 2013 and 2015, and the main subtype was CRF01_AE. A total of 2 surveillance drug-resistance mutation(SDRMs) and 3 SDRMs were found by analyzing the 47 sequences each year, sampled in 2013 and 2015, indicating that the prevalence of drug resistant HIV-1 stains was low in 2013, and moderate in 2015. A total of 5 individuals with drug resistant HIV-1 stains found in this study were mainly infected by homosexual transmission (3 cases), and the other two samples were different: one was infected by heterosexual transmission, the other was infected by IDU. The subtype was CRF01_AE (2 cases) , CRF07_BC (2 cases) and B (1 case) . SDRMs for protease inhibitor (PIs), nucleotide HIV-reverse transcriptase inhibitor (NRTIs) and non-NRTI (NNRTIs) were all found in the individuals with drug resistant HIV-1 stains.@*Conclusion@#CRF01_AE were the main HIV-1 subtypes of recently reported HIV-infected individuals in Shandong province, and the HIV-1 drug resistant strains transmission was catalogued as at low and moderate prevalence level in 2013 and 2015.
RESUMO
Objective This study aimed to analyze the behavior change and related factors regarding HIV/STD epidemics among female sex workers (FSWs) in Qingdao city.Methods According to the requirements set by the "National HIV/AIDS sentinel surveillance program",information on demographics,sexual and drug use behaviors,and HIV-related services among female sex workers (FSWs) was collected from ten consecutive annual cross-sectional surveys from 2006 to 2015.Blood samples were drawn for serological tests on both HIV and syphilis antibodies.Results Data from the sampled FSWs over the ten years,a higher proportion of participants who were aged 30 or more,married or cohabited and on-call FSW were followed.The prevalence of syphilis increased significantly from 1.0％ (4/420) in 2006 to 13.3％ (53/400) in 2015 (trendx2=54.22,P＜0.001).Rates on illicit drug use were ranging from 12.0％ (48/400) and 55.5％ (222/400) while the rate on consistent condom use with clients in the last month showed decreasing,with trendx2=170.62,P＜0.001.The proportion of HIV-related knowledge score ≥ 6 (trend x2 =152.96,P＜ 0.001),or ever been tested for HIV (trendx2=114.87,P＜0.001) were both significantly increased over the last ten years.Between 2009 and 2015,results from the annual stratified analysis showed that the FSWs who used drugs were more likely than the FSWs who were non-drug users less consistently using condoms with clients in last month and being syphilis positive (P＜0.05).On-call FSWs were more likely to be syphilis positive (P＜0.05) than the non on-call FSWs.Conclusions The prevalence of syphilis among FSWs in Qingdao city had been rising over the last ten years,with synthetic drug abuse as an important risk factor.Better targeted surveillance and intervention efforts among those drug-using FSWs seemed important to reduce the epidemics.
RESUMO
Objective To analyze the status and its factors associated with HIV/AIDS“90-90-90”-treatment-target in Shandong province,China.Methods Data regarding testing,treatment on HIV/AIDS in Shandong province by December 31,2015 was collected.Chi-square test and logistic regression model were used to analyze related factors associated with the “90-90-90”-treatment-target.Results Of the 11 700 estimated HIV/AIDS,61.2％ were diagnosed,of whom 74.4％ had received Highly active antiretroviral therapy (HAART).More than 80％ of the HIV/AIDS on HAART reached the criteria on viral suppression.HIV/AIDS infected by homosexual contacts were less likely to seek for diagnosis (P＜0.05).HIV/AIDS lived in Qingdao city (OR=1.30,95％CI:1.05-1.60),Yantai city (OR=1.53,95％CI:1.02-2.31) and Weihai city (OR=1.96,95％CI:1.07-3.58) were more likely to receive HAART.HIV/AIDS patients that infected through homosexual or (OR=O.12,95％CI:0.06-0.24) or heterosexual contacts (OR =0.13,95 ％CI:0.07-0.26),through injecting drug use (OR =0.08,95％CI:0.03-0.17) or being diagnosed at the custodial institutions (OR=0.29,95％CI:0.21-0.41)were less likely to receive HAART.HIV/AIDS patients who received HAART at medical institutions (OR=1.81,95％ CI:1.05-3.47) were more likely to meet the level of Viral load (VL) suppression.However,those who were infected through homosexual (OR=0.43,95％ CI:0.25-0.75) or heterosexual contacts (OR =0.49,95％CI:0.28-0.81) or diagnosed at the custodial institutions (OR =0.48,95％CI:0.28-0.80) were less likely to meet the criteria set for VL suppression.Conclusions There was a gap between the status of testing/treatment and the target on HIV/AID “90-90-90”-treatment,especially on the target set for testing,in Shandong Province.Both HIV testing and comprehensive care services need to be strengthened.

Objective To analyze the spatiotemporal characteristics of HIV/AIDS in Shandong province,2009-2015.Methods Data on HIV/AIDS between 2009 and 2015 were derived from the Shandong provincial HIV/AIDS Comprehensive Response Information Management System at the end of 2015.All the data were geographically referenced based on 139 spatial units in the related counties of Shandong province.Electronic maps were obtained from China CDC.Global Moran's I statistics and LISA statistics were used to detect the global and local spatial distribution patterns of HIV/AIDS in Shandong.Space-time scan statistics method,based on the Poisson Model,was used to detect the space-time clusters of HIV/AIDS.Results A total of 9 144 HIV/AIDS cases were reported during 2009-2015 in Shandong province.The scope of spatial distribution on HIV/AIDS expanded annually and concentrated in certain areas.Spatial distribution of HIV/AIDS in 2009 was randomized,and results showed spatial autocorrelation at the county level,during 2010-2015.Spatial hotspot-clusters mainly appeared in Tianqiao,Shizhong and Licheng districts of Jinan city,and Shinan,Laoshan districts of Qingdao city.Results from the Space-time scan analysis identified 5 spatiotemporal clusters in 2013-2015,including 1 most likely cluster and 4 secondary clusters which involving Lixia,Shizhong,Huaiyin and Tianqiao districts of Jinan city (RR=11.29,LLR=1 592.84,P＜0.001).The covered counties in secondary clusters appeared in Shinan,Shibei and Licang districts of Qingdao city (RR=7.35,LLR=682.40,P＜0.001),Weicheng and Kuiwen districts of Weifang city (RR=7.33,LLR=363.49,P＜0.001),Zhifu and Laishan districts of Yantai city (RR=7.66,LLR=117.63,P＜0.001),Zhoucun and Zhangdian districts of Zibo city (RR =6.09,LLR=268.68,P＜0.001)respectively.Conclusion HIV/AIDS cases in Shandong province appeared clustering features in both dimensions of time and space.Prevention efforts were needed to focus on HIV/AIDS highly clustered areas,such as Jinan city,Qingdao city,Zibo city,Weifang city and Yantai city.
RESUMO
Objective This study aimed to analyze the behavior change and related factors regarding HIV/STD epidemics among female sex workers (FSWs) in Qingdao city.Methods According to the requirements set by the "National HIV/AIDS sentinel surveillance program",information on demographics,sexual and drug use behaviors,and HIV-related services among female sex workers (FSWs) was collected from ten consecutive annual cross-sectional surveys from 2006 to 2015.Blood samples were drawn for serological tests on both HIV and syphilis antibodies.Results Data from the sampled FSWs over the ten years,a higher proportion of participants who were aged 30 or more,married or cohabited and on-call FSW were followed.The prevalence of syphilis increased significantly from 1.0％ (4/420) in 2006 to 13.3％ (53/400) in 2015 (trendx2=54.22,P＜0.001).Rates on illicit drug use were ranging from 12.0％ (48/400) and 55.5％ (222/400) while the rate on consistent condom use with clients in the last month showed decreasing,with trendx2=170.62,P＜0.001.The proportion of HIV-related knowledge score ≥ 6 (trend x2 =152.96,P＜ 0.001),or ever been tested for HIV (trendx2=114.87,P＜0.001) were both significantly increased over the last ten years.Between 2009 and 2015,results from the annual stratified analysis showed that the FSWs who used drugs were more likely than the FSWs who were non-drug users less consistently using condoms with clients in last month and being syphilis positive (P＜0.05).On-call FSWs were more likely to be syphilis positive (P＜0.05) than the non on-call FSWs.Conclusions The prevalence of syphilis among FSWs in Qingdao city had been rising over the last ten years,with synthetic drug abuse as an important risk factor.Better targeted surveillance and intervention efforts among those drug-using FSWs seemed important to reduce the epidemics.

RESUMO
The AIDS epidemic in men who have sex wlth men (MSM) in recent years showed a sharp upward trend, looking for behavioral intervention strategies should be imperative. Fear appeals by fear prompted intervention received intervention information, provide a new breakthrough to achieve better effect of propaganda and intervention. After over 70 years development, the Fear Appeal generated from the driver model that proposed the fear decided the effectiveness of behavior intervention, to the extended parallel process model theory which integrated protection motivation theory and parallel process theory, both of which believed the fear is just one of the estimators, suggested fear is the key factor. The fear appeal theory is turning to be even more comprehensive and accurate. As an important theoretical basement, the fear appeal is still developing, and need more work to make it perfection.

<p><b>OBJECTIVE</b>To analyze survival time of AIDS death cases receiving Antiretroviral Therapy and related factors.</p><p><b>METHODS</b>A retrospective cohort study was carried out to collect the data on death cases receiving Antiretroviral Therapy by the National HIV/AIDS Comprehensive Response Information Management System. Kaplan-Meier was used to calculate the median survival time, and compare survival time among different groups of age, sex, marriage status, infectious routes, WHO clinical stage, baseline CD4(+)T cell counts, and interval time from the start of ART to HIV confirmation. Life table and survival curve were applied to describe survival distribution. Cox proportional hazard model was used to determine the factors associated with the survival time.</p><p><b>RESULTS</b>Among 142 AIDS death cases, 125 (88.03%) were related with AIDS and 17(11.97%) were not. The total median survival time was 3.100 months (95%CI: 2.279-3.921). The cumulative survival rate was (52 ± 4)%, (33 ± 4)%, (26 ± 4)% in the first 3 months, 3-6 months, and 6-12 months. The median survival time of married or cohabitation group was 2.670 months (95%CI:1.470-3.870), and single (unmarried, divorced, separation, widowed) group was 5.870 months (95%CI: 2.617-9.123). The median survival time of WHO clinical stage I or II group was 5.870 months (95%CI: 3.989-7.751), and WHO clinical stage III or IV group was 1.700 months (95%CI: 0.885-2.515). The median survival time of baseline CD4(+)T cell counts ≤ 50 /µl group was 1.670 months (95%CI: 0.759-2.581), and 51-199 /µl group was 4.400 months (95%CI: 2.735-6.065), and ≥ 200/µl group was 7.100 months (95%CI: 0.000-14.542). The survival time was significantly different among different baseline marital status groups, different WHO clinical stage groups, and different CD4(+)T cell counts groups. The mortality risk of Single (unmarried, divorced, separation, widowed) group was 0.641 times of the risk in married or cohabitation group. The mortality risk of WHO clinical stage III or IV was 1.856 times of the risk in stage I or II. The mortality risk of baseline CD4(+)T cell counts 51-199 /µl group was 0.582 times of the risk in ≤ 50 /µl group, and ≥ 200 /µl group was 0.551 times of the risk in ≤ 50 /µl group.</p><p><b>CONCLUSION</b>The total median survival time was relatively short. Most AIDS deaths happened in the first 3 months or 3-6 months after they received Antiretroviral Therapy, and the mortality trend slowed down in the following months. Married or cohabitation, low-baseline CD4(+)T cell counts, or WHO clinical stage III or IV were found to be the risk factors associated with AIDS death cases receiving Antiretroviral Therapy.</p>
