The role of childhood left-behind experience on childhood trauma exposure and mental health outcomes: a propensity score matching (PSM) analysis.

BACKGROUND: China has a significant number of left-behind families. This study focuses on the long-term effects of childhood left-behind experience on different type of childhood trauma and mental health outcomes in later life development. METHODS: participants were 67 795 Chinese young adults. Psychosocial characteristics were screened by sleep quality, the nine-item Patient Health Questionnaire for depressive symptoms, the generalized anxiety disorder-7 for anxiety symptoms, trauma screening questionnaire for post-traumatic stress, a short form of the Childhood Trauma Questionnaire for childhood trauma. Propensity score matching (PSM) and multivariate linear regression were applied to analyze the data. RESULTS: the results of the post-PSM analysis showed that the distributions of propensity scores for the two groups were approximately equal. And the total sample size in post-analysis dropped to 2358 (Nnuclear family = 1179, Nleft-behind family = 1179), with unmatched cases excluded. Post-matching results showed that the students from left-behind family were significantly associated with severer post-traumatic stress (b = 0.39, 95% CI = [0.15, 0.62]), loneliness (b = 0.29, 95% CI = [0.16, 0.42]), depressive symptoms (b = 0.44, 95% CI = [0.06, 0.82]) and CTQ-physical neglect (b = 0.34, 95% CI = [0.11, 0.58]). CONCLUSION: our study showed that childhood left-behind experiences are tightly related to childhood trauma experience and mental health issues (post-traumatic stress, loneliness and depression) in late adolescents.

Symptom association between social anxiety disorder, appearance anxiety, and eating disorders among Chinese University students: A network analysis to conceptualize comorbidity.

Background: Incidences of social anxiety disorder (SAD), appearance anxiety, and eating disorders (ED) show an increased prevalence among young people. However, symptoms' associations between these disorders have not been investigated in depth. Network analysis is an approach that can be used to explain the relationship(s) between symptoms of different psychological disorders. Using network analysis, this study aimed to explore the association and potential interacting mechanisms between SAD, appearance anxiety, and ED. Methods: This study included 96,218 University students from Jilin Province, China. SAD, appearance anxiety and ED were assessed using the Social Anxiety Subscale of the Self-Consciousness Scale (SASS), the Appearance Anxiety Scale Brief Version (AASBV), and the Sick, Control, One, Fat, Food questionnaire (SCOFF), Chinese versions. Network analysis was employed to investigate the symptom associations, while the stability of the network model was analyzed using statistical measures. Results: The prevalence of ED among the total sample was 38% (95% CI: 38.1-38.8%), while this figure was 31.2% (95% CI: 30.7-31.6%) in males and 43.6% (95% CI: 43.2-44.0%) in females. Additionally, the total score of SAD was significantly higher in females (11.83 ± 5.37) than it in males (10.02 ± 5.46) (P < 0.001). While the total score of appearance anxiety was also different significantly in gender (39.21 ± 9.49 in females vs. 38 ± 9.42 in males) (P < 0.001). Results showed that ED was associated with all three aspects of appearance anxiety, including "appearance concern," "appearance satisfaction," and "wish for good looks." Appearance anxiety and SAD were also associated; specifically, symptoms of "appearance satisfaction" were significantly associated with the symptoms "easily talk to strangers" and "appearance concern", which was also significantly associated with "embarrassed". Compared with males, females showed significantly stronger associations with appearance anxiety symptoms, while ED symptoms were associated with "troubled by being watched" and "appearance concern". Conclusion: Appearance anxiety was associated with both ED and SAD symptoms. ED may have a potential relationship with SAD, affecting appearance anxiety indirectly. Significant differences were found among males and females in symptom associations between appearance anxiety and SAD. This study therefore clarified that young people should have body-positive interventions and challenge the normative body image discourse, which may help alleviate symptoms of SAD and ED.
