Loneliness and social isolation in people with HIV

PURPOSE OF REVIEW: Antiretroviral therapy (ART) has significantly extended the life expectancy of people with HIV (PWH). However, as this population ages, they face increased risk of social isolation and loneliness (SIL), driven by stigma, discrimination, and shrinking social networks. SIL is a major public health issue, closely linked to mental health conditions, reduced adherence to treatment, and lower health-related quality of life (HRQoL). This review examines the prevalence, risk factors, health impacts, and interventions related to SIL, highlighting its critical importance for improving HRQoL in PWH. RECENT FINDINGS: SIL is common among PWH and strongly associated with HIV-related stigma, depression, anxiety, and systemic inflammation. These factors accelerate aging and contribute to chronic conditions while undermining ART outcomes. Recent research supports the effectiveness of interventions like psychological therapies and social prescribing in reducing SIL and improving HRQoL. However, progress is limited by the lack of standardized tools to assessment SIL, which hampers consistent research and the development of targeted solutions. SUMMARY: Addressing SIL is essential to advancing holistic and person-centered HIV care. Integrating SIL evaluation into routine clinical practice, creating standardized assessment tools, and implementing targeted interventions can improve HRQoL and reduce health burdens, particularly as the aging PWH population grows.
