We examined the trajectories of sleep problems in adolescents after the Wenchuan earthquake, and assessed predictors such as posttraumatic stress disorder symptoms. We surveyed adolescents at 1, 1.5, 2, and 2.5 years after the Wenchuan earthquake. In total, 391 adolescents completed self-report questionnaires. We identified five latent sleep problem trajectories, specifically, U-shaped (3.8%), low-stable (68.0%), high-stable (10.8%), increasing (8.7%), and decreasing (8.7%) trajectories. Additionally, we found that posttraumatic stress disorder hyper-arousal symptoms were more frequent in individuals who had non-low-stable trajectories. Adolescents in the U-shaped group were less likely to have intrusive symptoms. After natural disasters, consequent sleep problems in adolescents do not remain stable over time, and sleep problem trajectories had considerable heterogeneity.
我们研究了汶川地震后青少年睡眠问题的轨迹，并评估了创伤后应激障碍症状等预测因素。我们在汶川地震后 1、1.5、2 和 2.5 年对青少年进行了调查。共有 391 名青少年完成了自我报告问卷。我们确定了五种潜在的睡眠问题轨迹，分别是 U 形（3.8%）、低稳定型（68.0%）、高稳定型（10.8%）、递增型（8.7%）和递减型（8.7%）。此外，我们发现创伤后应激障碍过度唤醒症状在非低稳定型轨迹的个体中更为常见。U 型组的青少年较少出现闯入性症状。自然灾害后，青少年的睡眠问题不会随着时间的推移而保持稳定，并且睡眠问题轨迹存在相当大的异质性。
