Outline
To explore the causal relationship among depressive symptoms in young men who have sex with men young (YMSM) in central China.
A total of 349 eligible YMSM who were recruited in Wuhan, Changsha, and Nanchang in 2017 and completed three rounds of follow-up in 2018 and 2019 were selected as research subjects. The depressive symptoms of the subjects were measured by the center for epidemiological survey-depression scale (CES-D), and the longitudinal network structure of depression was analyzed by cross-lag network.
During the period from baseline to the first round of follow-up, the statistical value of output centrality of loneliness was 3.541, which had the highest impact on other symptoms, followed by dislike for themselves (1.196). The central statistical value of unhappy input was 2.175, followed by boredom (1.124) and bitterness (1.093), indicating that these symptoms were most easily predicted by other symptoms. During the first round of follow-up to the second round of follow-up, unfriendliness (2.440) was the symptom with the highest impact on output expectations, followed by inability to perform daily work (1.708) and dislike for themselves (1.119). Fear (2.437), arduous work (1.374), and hopelessness (1.278) were the most easily predicted by other symptoms. In the YMSM depressive symptom network, loneliness (3.541), unfriendliness (2.440), and dislike for themselves (1.196) constituted a small symptom group, which occupied the core position of the network.
Interpersonal relationship plays an important role in the network structure of depressive symptoms in YMSM population. Future interventions should fully consider this and reduce YMSM depression by promoting social interaction and social integration of YMSM groups.
