Chronic pain is a primary health problem in people living with HIV (PWH). However, there is limited research regarding chronic pain among PWH in Chinese health care settings. To investigate biopsychosocial factors of chronic pain severity, we conducted a crosssectional study in Shenzhen, China. Chronic pain was defined as pain lasting for more than three months. Pain intensity was measured using the numeric rating scale (NRS). Among 123 hospitalized PWH, 78.86% of participants had mild pain and 21.14% had moderate-severe pain. Multiple logistic regression results indicated thatPWHin moderate-severe pain group were more likely to have higher levels of interleukin [IL]-6 (OR51.034, 95% CI: 1.003-1.066, p5.029) and anxiety (OR51.334, 95% CI: 1.071-1.662, p5.010) than those in the mild chronic pain group. Targeted pain management interventions should be explored in clinical practices and future studies regarding PWH with high levels of IL-6 and anxiety. [ABSTRACT FROM AUTHOR]
