Outline
To explore the longitudinal bidirectional relationship between depressive symptoms and HIV infection risk behaviors among young men who have sex with men (YMSM).
A longitudinal study design was used to recruit 489 YMSM from September 2017 to January 2018 (T1), and two follow-up surveys were completed from July to September 2018 (T2) and from June to July 2019 (T3), respectively. The cross-lagged path analysis model was used to analyze the causality, time series relationship and interactive direction between depressive symptoms and HIV infection risk behaviors.
Data of 347 YMSM were analyzed using cross-lagged path analysis. The results showed that T1 depressive symptoms significantly and positively predicted T2 HIV infection risk behaviors (β=0.071, 95% CI: 0.000-0.142), and T2 depressive symptoms significantly and positively predicted T3 HIV infection risk behaviors (β=0.072, 95% CI: 0.000-0.143). However, T1 HIV infection risk behaviors did not significantly predict T2 depressive symptoms and T2 HIV infection risk behaviors did not significantly predict T3 depressive symptoms.
Depressive symptoms among YMSM significantly and positively predicted HIV infection risk behaviors, with a unidirectional causal temporal relationship. Therefore, the level of depressive symptoms should be considered as an essential factor in HIV infection risk behavior interventions for YMSM.
