Article Abstract
Objective: People living with HIV (PLWH) frequently experience pain, which often co-occurs with psychological symptoms and may impact functional outcomes. We investigated cross-sectional associations between pain, depressive symptoms, and inflammation, and then explored whether pain was related to poorer physical function among older PLWH.
Methods: We examined data from PLWH aged 54 to 78 years ( n = 162) recruited from a single outpatient program for a larger study on HIV and aging. Participants reported depressive symptoms (10-item Center for Epidemiological Studies Depression Scale) and then attended a biomedical visit in which they reported past-month pain (Medical Outcomes Study-HIV pain subscale), completed physical function assessments, and provided blood samples (assayed for interleukin 6, interferon-γ, tumor necrosis factor α, and C-reactive protein). Links between pain, depressive symptoms, inflammation, and physical function were tested using linear regression models.
Results: PLWH with greater depressive symptoms experienced more pain than did those with fewer depressive symptoms ( B = 1.31, SE = 0.28, p < .001), adjusting for age, sex, race, body mass index, smoking, disease burden, time since HIV diagnosis, and medication use. Higher composite cytokine levels were associated with worse pain ( B = 5.70, SE = 2.54, p = .027 in adjusted model). Poorer physical function indicators, including slower gait speed, weaker grip strength, recent falls, and prefrail or frail status, were observed among those with worse pain. Exploratory mediation analyses suggested that pain may partially explain links between depressive symptoms and several physical function outcomes.
Conclusions: Pain is a potential pathway linking depressive symptoms and inflammation to age-related health vulnerabilities among older PLWH; longitudinal investigation of this pattern is warranted. PLWH presenting with pain may benefit from multidisciplinary resources, including behavioral health and geriatric medicine approaches.
