Combined effects of older age and HIV disease on changes in everyday functioning over one year
Abstract Older age and HIV disease are independent risk factors for problems in many aspects of everyday functioning. However, less is known about how these risk factors may combine to influence everyday functioning over time. The current study examined the possible combined effects of age and HIV serostatus on change in everyday functioning over a 1-year period and its specific associations with changes in neurocognition. A repeated measures factorial design was employed. Participants included 77 older persons with HIV (PWH), 35 younger PWH, 44 older HIV-, and 27 younger HIV-adults who each completed baseline and follow-up visits approximately 14 months apart. Everyday functioning was assessed using a standardized self-report measure of activities of daily living (ADLs) at each visit. A comprehensive clinical battery assessed six domains of neurocognition. Raw scores on each neurocognitive measure were converted to sample-based z-scores, from which a global neurocognitive z-score was derived. Older PWH reported the poorest everyday functioning at baseline and follow-up visits at medium-to-large effect sizes. However, these ADL disruptions among older PWH were relatively stable over time, differing significantly from younger PWH who evidenced mild ADL improvements from baseline to follow-up. Within the entire sample, everyday functioning at baseline predicted neurocognitive performance at follow-up, but the reciprocal relationship was not significant. Older adults with HIV have high rates of ADL problems, which appear stable over 1 year, the trajectory of which differed from younger adults with HIV for whom mild improvements were observed. Importantly, the results also suggest that problems with ADLs may sometimes precede neurocognitive declines. Further examination of longitudinal data is needed to elucidate the long-term trajectory of neurocognitive and functional changes in older PWH to support early detection and proper management of clinical care..
