What are the key targets to improve quality of life among MSM living with HIV on antiretroviral therapy? A network analysis.

PURPOSE

The study aimed to assess the interconnection of quality of life (QoL) variables and identify key areas for which interventions could improve QoL among men who have sex with men (MSM) living with HIV on antiretroviral therapy (ART).

METHODS

A cross-sectional study was conducted in Jinan of Shandong Province, between October to December 2020. Undirected network analyses were conducted to examine and visualize the interconnections between QoL variables among MSM living with HIV. Centrality indices, including strength, betweenness, closeness, and expected influence (EI), were calculated to quantify the importance of each variable in the network. A network comparison test was used to assess differences between networks of individuals who initiated ART before and after the introduction of "Treat-All" strategy, comparing network structure, edge strength, and global strength.

RESULTS

A total of 584 participants were included, with an average overall QoL score of 87.80±12.75. At the domain level, psychology (EI=1.04) emerged as the most central domain within the QoL network. At the item level, satisfaction with the ability to perform activities of daily living showed the highest EI (1.25), followed by access to information (EI=1.12). No significant differences were observed in network structure (Test statistic M=0.21, P=0.317) and global strength (Test statistic S=0.64, P=0.056) between the networks for men who initiated ART before and after the introduction of "Treat-All" strategy.

CONCLUSION

Psychological well-being emerged as the most central QoL domain for MSM with HIV on ART, with daily living abilities and information access being key aspects. Thus, HIV care should incorporate interventions improving these and mental health.
