The objective of this study was to explore the relationship between sedentary behavior and non-suicidal self-injury (NSSI), and to provide a theoretical basis for preventing and reducing the occurrence of NSSI behavior and the development of intervention measures.
Between September and December 2021, a sedentary behavior and NSSI survey was administered to 10327 Chinese adolescents aged 12-17 who had been randomly selected using the stratified cluster random sampling method. The results were analyzed using the chi-square test and logistic regression analysis to explore the relationship between sedentary behavior and NSSI in this population.
The study found an overall NSSI detection rate among the participants of 25.1%, with occasional NSSI and frequent NSSI detection rates of 11.0% and 14.1%, respectively. The NSSI detection rate is higher in girls than in boys. After controlling for related influencing factors, the NSSI detection rates among adolescents with sedentary behavior duration ≥8 hours and screen time ≥2 hours were 1.393(= 0.332, <0.01) and 1.569(= 0.451, <0.01) times higher than those with sedentary behavior duration <8 hours and screen time <2 hours, respectively.
Sedentary behavior, especially that related to screen time is closely related to the occurrence of NSSI in adolescents. To reduce the occurrence of NSSI, we should therefore pay attention to the harmful effects of sedentary behavior on the physical and mental health of teenagers, take corresponding measures to limit sedentary behavior and screen time, and guide teenagers to use electronic devices correctly.
本研究旨在探讨久坐行为与非自杀性自伤（NSSI）之间的关系，为预防和减少NSSI行为的发生及制定干预措施提供理论依据。
2021年9月至12月，采用分层整群随机抽样方法，对10327名年龄在12 - 17岁的中国青少年进行了久坐行为与NSSI调查。采用卡方检验和逻辑回归分析对结果进行分析，以探讨该人群中久坐行为与NSSI之间的关系。
研究发现，参与者的总体NSSI检出率为25.1%，偶尔NSSI和频繁NSSI检出率分别为11.0%和14.1%。女孩的NSSI检出率高于男孩。在控制相关影响因素后，久坐行为时长≥8小时且屏幕使用时间≥2小时的青少年的NSSI检出率分别比久坐行为时长<8小时且屏幕使用时间<2小时的青少年高1.393（= 0.332，<0.01）倍和1.569（= 0.451，<0.01）倍。
久坐行为，尤其是与屏幕使用时间相关的久坐行为，与青少年NSSI的发生密切相关。因此，为减少NSSI的发生，应关注久坐行为对青少年身心健康的有害影响，采取相应措施限制久坐行为和屏幕使用时间，并引导青少年正确使用电子设备。
