儿童青少年创伤后应激障碍与睡眠时长的纵向研究.

Objective To investigate the association between sleep duration in children and post -traumatic stress disorder (PTSD) and its three core symptoms: intrusion, avoidance, and hyperarousal. Methods Data from the Chengdu ChildrenJ s Positive Growth Cohort (CPCD) collected in June 2021 and June 2022 during the period of the COVID-19 epidemic were used. The Children s Revised Impact of Events Scale-13 (CRIES-13) was used to measure PTSD symptoms, and sleep status were collected. Spearman analysis was used to explore the between PTSD and its three core symptoms and sleep duration and sleep quality. The cross-lagged panel model was used to explore the between sleep duration and PTSD symptoms. Results A total of 5 035 children aged 7 to 15 years were included. The detection rates of PTSD in the two rounds were 14.5% and 9.9%, respectively. Sleep duration was positively associated with PTSD and PTSD avoidance symptoms in both rounds (P< 0.05). PTSD avoidance symptoms and sleep duration in the previous survey predicted PTSD avoidance symptoms and sleep duration in the following survey (6=0.06, P<0.05). Conclusion There is a bidirectional predictive relationship between the sleep duration of children and adolescents and avoidance symptoms in PTSD, suggesting that prolonged sleep is one of the mechanisms used by children and adolescents with PTSD symptoms to avoid traumatic memory.
