Abstract:
Objective:To explore the relationship between illness perceptions and disability, and the relative importance of association of illness perceptions items and disability in HIV-infected people aged ≥50 years in Sichuan Province.Methods:By using multi-stage cluster sampling, the baseline data of a cohort of HIV-infected people aged ≥50 years in 5 counties (district) in Sichuan were obtained from 2018 to 2021. The disability was evalauted with instrumental activities of daily living scale (IADL), and the illness perception was evaluated by using brief illness perception questionnaire. General additive model and general linear model were used to analyze the association between illness perceptions and IADL. Weighted sum quartile sum regression was used to find the dominant items on the association. Software R was used for statistical anlysis.Results:A total of 1 587 HIV-inbfected peoeple aged ≥50 years were included in this study. The prevalence of disability was 26.1% ( n=414). The median score of illness perception was 33. The illness perceptions had a negative effect on the IADL score ( β=-0.15, P<0.001) and the partial score of IADL declined when illness perception score was larger than 38 ( P<0.05). Personal control (32.98%) and consequence (22.50%) whose weight were higher than average (12.50%) were the dominant items on the association between the score of illness perception and IADL score. Conclusions:The prevalence of disability in HIV-infected people aged ≥50 years in Sichuan was high. It is necessary to intervent on personal control and consequence in HIV-infected people aged ≥50 years when their illness perception scores are high to prevent the incidence and development of disability.
