Abstract:
Objective:To understand the epidemiological characteristics of HIV-infected farmers aged ≥60 years in China and provide evidence for the development of AIDS prevention and control policies for elderly farmers.Methods:Data of newly HIV-infected farmers aged ≥60 years reported between 2018 and 2022 were obtained from China Information System for Disease Control and Prevention. The differences in epidemiological characteristics of HIV infection between farmers and other populations were compared using χ2 test. Based on 6 representative indicators, 31 provinces were divided into three sub-epidemic areas of A, B, and C by using sample system clustering method in SPSS 24.0 software. Results:From 2018 to 2022, a total of 113 311 HIV infection cases in farmers aged ≥60 years were reported, accounting for 71.8% of the reported cases in this age group nationwide (113 311/157 792). In the 113 311 HIV infection cases, 86 517 (76.4%) were men, 80 176 (70.8%) were diagnosed by medical institutions, 80 667 (71.2%) were distributed in the western region and 92 191 (81.4%) had education level of primary school or below [higher than the proportion in other populations (49.8%, 22 165/44 481)]. In 113 311 HIV infection cases, 96.7%(109 562/113 311) were infected through heterosexual transmission, in whom 50.4% (55 184/109 562) had commercial heterosexual behavior, 9.1%(9 958/109 562) had fixed sexual partners, 40.5%(44 420/109 562) had other heterosexual behaviors. The clustering analysis indicated that in region A (Guangxi, Chongqing, Guizhou, Sichuan, Yunnan and Xinjiang), the proportions of people living with HIV (30.2/10 000), HIV-infected farmers aged ≥60 years in rural population (22.8/10 000), counties reported HIV-infected elderly farmers (93.4%), the population had HIV test (44.2%), were all higher than those in region B and C. Compared with region B and C, The net income of farmers (10 000 yuan) was lower in region A, and the proportion of commercial heterosexual behavior in male farmers in region A (41.0%) was slightly lower than that in region B (46.1%), but higher than that in region C (15.2%).Conclusions:HIV infections in farmers aged ≥60 years were mainly caused by heterosexual behaviors, such as commercial heterosexual sex, in China from 2018 to 2022. The low awareness of self-protection against AIDS and high-risk sexual behaviors are closely associated with HIV infection in elderly farmers. Attention should be paid to the behavior intervention and health education about AIDS prevention in elderly farmers and the prevention and intervention in rural female sex workers and HIV positive spouses should be strengthened.
