目的探讨青少年夜间使用手机与心理健康、自杀倾向和自伤的关系。方法对17920名青少年熄灯后使用手机与心理健康、自杀倾向和自残的关系进行横断面调查。对早期（7-9年级）和晚期（10-12年级）青少年分别进行了一系列逻辑回归分析。结果仅在青少年早期，睡眠时间与手机使用有显著相关性。逻辑回归显示，在控制了睡眠时间长短和其他混杂因素后，夜间使用手机与心理健康状况不佳、自杀倾向和自残存在显著关联。结论熄灯后使用手机可能与青少年早期和晚期的心理健康状况不佳、自杀倾向和自残有关。睡眠减少和手机使用之间的联系仅限于青少年早期。
Objective To study association between nocturnal mobile phone use and mental health, suicidal feelings, and self-injury in adolescents. Methods Associations of mobile phone use after lights out with mental health, suicidal feelings, and self-injury were cross-sectionally examined in 17,920 adolescents using a self-report questionnaire. A series of logistic regression analyses were separately conducted for early (grades 7-9) and late (grades 10-12) adolescents. Results Sleep length was significantly associated with the mobile phone use only in early adolescents. Logistic regression showed significant associations of the nocturnal mobile phone use with poor mental health, suicidal feelings, and self-injury after controlling for sleep length and other confounders. Conclusions Mobile phone use after lights out may be associated with poor mental health, suicidal feelings, and self-injury in both early and late adolescents. Association between reduced sleep and the mobile phone use was confined to early adolescents.
