RESUMO
Objective@#To analyze the epidemiological characteristics of newly diagnosed HIV/AIDS cases aged 50 years or over in Zhejiang Province from 2015 to 2019, so as to provide reference for the development of prevention and control strategies.@*Methods @#The data of newly diagnosed HIV/AIDS cases in Zhejiang Province were collected through the China HIV/AIDS Comprehensive Response Information Management System, and the demographic characteristics, infection routes,regional distribution and time distribution of the cases were analyzed. @*Results@#A total of 6 726 HIV/AIDS patients were recruited in this study, and the number of new patients from 2015 to 2019 showed an increasing trend ( P <0.05 ) . The number of participants diagnosed at the age of 50-59, 60-69 and 70-91 years old were 3 433( 51.04% ), 2 242 ( 33.33% ) and 1 051 ( 15.63% ). The majority of them were males ( 5 180, 77.01% ) , married ( 4 286, 63.72% ) , Zhejiang residents ( 5 304, 78.86% ) , and lived in rural areas ( 4 095, 60.88% ) . In terms of exposure history,6 586 cases ( 97.92% ) were infected by sexual contact. Among the 5 083 males infected by sexual contact, 82.63% were through heterosexual contact, 94.79% had extramarital sex partners, among whom 76.61% were commercial sex partners. The married women patients who confirmed HIV positive accounted for 75.44%. There were increasing trends in the proportion of the cases living in rural areas, male cases infected through heterosexual contact and those with extramarital and commercial sex partners, and female cases with their husbands positive along with age ( P <0.05 ) . @*Conclusions@#The number of newly diagnosed HIV/AIDS cases aged ≥50 years is increasing in Zhejiang Province. Many of them live in rural areas. Commercial sexual contact is the main route of HIV transmission among males and further lead to HIV transmission within couples.
RESUMO
Objective@#To analyze the characteristics and influencing factors of the newly diagnosed cases locally infected with HIV through sexual contact in Jinhua,so as to provide reference for AIDS prevention and control.@*Methods@#An epidemiological survey was conducted among the HIV/AIDS cases diagnosed in 2017 in Jinhua to collect the information about demographic characteristics,local infection and sexual behaviors. The logistic regression model was used to analyze the related factors for local HIV infection. @*Results@#A total of 438 HIV/AIDS cases infected through sexual contact were recruited,with 272（62.10%）cases infected in Jinhua. The proportion of local infection was 86.67%,79.47%,63.04%,69.09%,77.46% and 77.97%,respectively,among those people aged 60 years or over,permanent residents in Jinhua,employees / students,farmers,those who had lived in Jinhua for more than five years,and those who had a HIV testing in one year. The Results of the multivariate logistic regression analysis showed that heterosexual transmission cases who were permanent residents in Jinhua（OR=3.437,95%CI：1.250-9.451）,who had lived in Jinhua for more than five years（OR=3.609,95%CI：1.403-9.284）,who had commercial heterosexual behaviors in Jinhua（OR=5.463,95%CI：2.529-11.803）were more likely to be infected with HIV in Jinhua;homosexual transmission cases who were permanent residents in Jinhua（OR=4.812,95%CI：1.744-13.275）and who had non-commercial,temporary homosexual behaviors in Jinhua（OR=10.641,95%CI：4.369-25.916）were more likely to be infected with HIV in Jinhua. @* Conclusion@#Among the HIV/AIDS cases diagnosed in 2017 infected through sexual contact in Jinhua,having permanent residence,long-term residence,commercial heterosexual behaviors and non-commercial,temporary homosexual behaviors were risk factors for local infection.
RESUMO
Objective@#To understand the epidemiological characteristics and differences of HIV-positive cases among 15-24 years old in Jiaxing city and provide evidence for the development of targeted prevention and control measures.@*Methods@#A descriptive epidemiological method was used to analyze the data of HIV cases aged 15-24 reported in Jiaxing from 1999 to 2018.@*Results@#A total of 375 cases of young HIV were reported in 1999-2018, with an average age of 21.29±1.90 years, of which 42 were students. The ratio of male to female was 2.47∶1. The proportion of foreign household registration was higher (76%, 285 cases). The proportion of off-campus youth cases in total cases showed a downward trend(χ2=8.26, P=0.00), but the proportion of student cases showed an upward trend(χ2=15.73, P<0.01). Off-campus youth cases were mainly heterosexual transmission(59.16%, 197 cases), and the students’ cases were mainly homosexual transmission(88.10%, 37 cases). There were significant differences in gender, age, household registration, education level, route of transmission, late detection, CD4 level and source of detection among students and off-campus adolescents(P<0.05).@*Conclusion@#The prevalence of AIDS in adolescents and students is worthy of attention. The characteristics of adolescents inside and outside the school are different. Targeted prevention measures should be taken to reduce the harm of AIDS to young people.
