ABSTRACT
Objective@#To investigate the migration characteristics and follow-up treatment among HIV/AIDS patients after HIV confirmation in Yiwu City, Zhejiang Province from 2016 to 2020, so as to provide insights into the optimization of the HIV/AIDS control strategy among floating populations.@*Methods@#The reported HIV/AIDS patients' demographics, follow-up and treatment data in Yiwu City from 2016 to 2020 were captured from the HIV/AIDS Prevention and Control Information System of Chinese Disease Control and Prevention Information System. The migration characteristics, antiretroviral therapy and outcomes of HIV/AIDS patients were analyzed after HIV confirmation, and the factors affecting the migration of HIV/AIDS patients after HIV confirmation were identified using a Cox proportional hazard regression model.@*Results@#A total of 1 189 HIV/AIDS patients were enrolled, including 988 men (83.10%) and 806 cases without Zhejiang provincial household registration (67.79%). There were 441 patients (37.09%) migrating out of Yiwu City after HIV confirmation, with a migration rate of 17.73/100 person-years, and there were 366 patients migrating out of Zhejiang Province, with a cross-province migration rate of 30.78%. Among participants without Zhejiang provincial household registration, 395 patients (49.01%) migrated out of Yiwu City, including 337 patients (85.32%) returning to their household registration provinces, which mainly included Yunnan, Sichuan, Guizhou and Hunan. Cox proportional hazard regression analysis showed a high risk of migration among minority ethnic populations (HR=1.375, 95%CI: 1.044-1.811), retires (HR=3.605, 95%CI: 1.771-7.335), students (HR=8.969, 95%CI: 4.095-19.645), patients without Zhejiang provincial household registration (HR=4.545, 95%CI: 3.164-6.529) and patients identified through physical examination of floating populations or employees (HR=1.318, 95%CI: 1.006-1.727), and a low risk among married patients with spouses (HR=0.721, 95%CI: 0.569-0.913) and with an educational level of junior high school and above (HR: 0.428~0.753, 95%CI: 0.280-0.952). Among all floating HIV/AIDS patients, there were 26 cases lost to follow-up (5.90%) and 49 deaths (11.11%). In addition, the proportion of absence of antiretroviral therapy, HIV infection progressing into AIDS patients and failure in HIV inhibition were all greater among floating HIV/AIDS patients than among non-floating patients (P<0.05).@*Conclusions@#A high risk of migration was found among HIV/AIDS patients without Zhejiang provincial household registration, unmarried patients, patients with a low education level, retirees, students, and patients identified through physical examination of floating populations or employees in Yiwu City from 2016 to 2020, and migration does not facilitate the sustainability of antiretroviral therapy and follow-up, which may affect the prognosis of HIV/AIDS.
ABSTRACT
Objective@#To understand the awareness of HIV testing results before having sex among men who have sex with men （MSM） .@*Methods@#The MSM from a gay bar in Zhejiang Province were recruited through convenience sampling method. A questionnaire survey was conducted to collect the information about demographic characteristics,sexual behaviors,awareness of HIV status between sexual partners and HIV testing results during August of the year 2016. The awareness of HIV testing results before having sex among MSM and the influencing factors were analyzed .@*Results@#A total of 124 MSM were recruited in this study,56.56% of whom aged from 25 to 39 years,and 61.29% were single,divorced or widowed. The number of sexual partners they had in the last year ranged from 1 to 40,with median of 8. The MSM who had casual sexual partners accounted for 70.97%. The MSM who had regular HIV testing accounted for 90.32%,yet who would like to share the HIV testing reports with partners only accounted for 18.55%. Whether asking about the HIV status before having sex or not was associated with age,marriage status,the number and characters of sexual partners（P<0.05）. The MSM who were informed of the HIV status of commercial partners,casual partners and regular partners accounted for 0,5.10% and 19.77%,respectively. The main reasons for MSM not knowing about the HIV status of their sexual partners were“condom use would prevent HIV infection”（78.38%）,“never thought about HIV infection”（53.15%）,and “there was no need to ask as the partner looked healthy”（36.94%） .@*Conclusion@#The proportion of MSM who were aware of HIV testing results before having sex was not high and was associated with age,marriage status,the number and characters of sexual partners. Lack of knowledge about HIV infection might contributed to this low proportion.
ABSTRACT
Objective To understand the sources and characteristics of newly reported HIV/AIDS cases in Yiwu,Zhejiang province,from 2015 to 2016.Methods From January 1,2015 to December 31,2016,newly reported HIV/AIDS cases in Yiwu were recruited in the study and they were asked to complete an in-depth field epidemiology questionnaire.Information related to their previous sexual behaviors and infection sources or routes were collected in the survey.The data were processed and analyzed with EpiData 3.0 and SPSS 19.0 software.Results A total of 320 participants from 393 newly reported HIV/AIDS cases in Yiwu during this period were surveyed and recruited in the study.Most of them were males (268,83.8％),unmarried (141,44.1％),aged between 25-44 years (166,51.9％),had census register in other provinces (217,67.8％) and educational level of junior high school (128,40.0％).Among 305 cases whose infection times could be determined,107 (35.1％) were newly infected within one year,and among 267 cases whose infection location could be determined,200 (74.9％) were infected in Yiwu.New infections were mainly detected in those who had homosexual behaviors or causal sex partners (during the past year) and through active detection approach.Local infections were mainly among those who had local residence and commercial heterosexual behavior in Yiwu.Conclusions Most newly reported HIV/AIDS cases in Yiwu from 2015-2016 were infected for more than one year and locally infected.Census registration of other provinces,homosexual sexual behavior,and casual sexual behavior give major contribution to HIV/AIDS epidemic in Yiwu.
