To analyze the epidemiological characteristics of HIV-infected cases among farmers in Guizhou Province and provide a scientific basis for formulating AIDS prevention and control strategies.
The data of AIDS cases reported among farmers in Guizhou Province from 2010 to 2022 were selected from the Chinese AIDS Comprehensive Prevention and Control Information System. Descriptive epidemiological methods were used to analyze the epidemic characteristics, and a linear regression model was constructed with the year as the independent variable and the number of cases as the dependent variable to analyze the changing trend.
From 2010 to 2022, 47 811 HIV/AIDS cases were reported among farmers in Guizhou Province, accounting for 60.40% of the total number of cases. The number of reported cases showed an upward trend (AAPC=23.10%). The male-to-female ratio of the cases was 2:1. The majority of the cases were over 50 years old (56.55%),and the number of cases in each age group showed an overall upward trend. The main mode of transmission was heterosexual transmission (97.74%), and non-commercial heterosexual intercourse was the main mode for both males (49.01%) and females (61.50%). The samples were mainly sourced from medical institution tests (76.56%), and the proportion of late detection was 74.97%.
From 2010 to 2022, the number of reported HIV/AIDS cases among farmers in Guizhou Province showed an upward trend. The cases were mainly elderly, with a high proportion of late detection, relatively low educational levels, and heterosexual contact was the main mode of transmission, mainly non-commercial heterosexual intercourse. Attention should be paid to the HIV epidemic among farmers, and AIDS prevention and control strategies targeting farmers need to be explored according to the characteristics of this population.
