Outline
To analyze how population aging affects HIV/AIDS incidence and mortality, and to explore the modifying role of socioeconomic factors in this association.
Data on reported HIV/AIDS incidence and mortality, demographic structure, and socioeconomic indicators were collected from 31 provinces in mainland China between 2004 and 2020. A Bayesian spatio-temporal model was constructed with the proportions of different age groups as key explanatory variables. Covariates included per capita gross domestic product (GDP), number of health institutions, population density, sex ratio, education leveland annual mean temperature. The modifying effects of socioeconomic indicators were also analyzed.
At the national level, each 1% increase in the proportion of the population aged 0-14 years was associated with a 1.1% increase in the relative risk of HIV/AIDS mortality (95%CI: 1.001-1.021). Each 1% increase in the proportion of the population aged ≥65 years was associated with a 2.0% increase in the relative risk of HIV/AIDS incidence (95%CI: 1.006-1.033) and a 1.8% increase in the relative risk of HIV/AIDS mortality (95%CI: 1.004-1.033).The effect modification analysis showed that, across different strata of sex ratio and education level, population aging was significantly positively associated with HIV/AIDS incidence and mortality, while the linear trends of sex ratio and education level on incidence and mortality were not significant.
The progression of population aging increases the relative risk of HIV/AIDS incidence and mortality, and sex ratio and education level may partially modify the association between aging and HIV/AIDS.
