ABSTRACT
The prevalence of HIV/AIDS in people aged ≥50 years is increasing in China, resulting in another focus for AIDS prevention and control. A Meta-analysis was conducted to evaluate the HIV infection, its area and time distributions in people aged ≥50 years in China to provide evidence for the prevention and control of HIV/AIDS. Information on HIV infection rate in people aged ≥50 years in China were collected from Wanfang digital database, China National Knowledge Infrastructure (CNKI), PubMed and Embase. The R Studio1.1.456 software was used to calculate the pooled infection rate, and assessed the publication bias. A total of 30 studies which covered 13 provinces were selected. From 2010 to 2018, the pooled HIV infection rate in people aged ≥50 years was 1.68 (95:1.00-2.79). The HIV infection rate (2.60) was higher in eastern China than in central and western China (0.16 2.13). The overall HIV infection rate in people aged ≥50 years is generally high in China. It is important to control the HIV infection in this population to facilitate the AIDS prevention and control in China.
