The impact of biological rhythm disorder (BRD) on the association of childhood maltreatment (CM) and suicidal behavior in adolescents remains unclear. CM increases the risk of suicidal ideation (SI), suicidal planning (SP), and suicidal attempts (SAs). There is less investigation on gender differences in CM's effects on suicidal behavior. It is unknown whether the impacts vary with different levels of BRD.
To identify gender differences in CM's effects on suicidal behavior and to investigate these impacts at different levels of BRD.
The analysis is based on data from 7,986 adolescents recruited from three cities in China between October and December 2019. All participants, aged 14.7 ± 2 years, filled out standard questionnaires involving CM, BRD, and suicidal behavior.
A total of 22.9, 10.8, and 4.7% of the adolescents reported SI/SP/SAs in the past year. Girls are more likely to engage in SI and SP when exposed to the highest level of CM; boys are more likely to engage in SAs than girls. A significant relationship between moderate levels of CM and SI/SP/SAs was only observed in girls exposed to low BRD. Moderate CM is only significantly associated with SI in boys exposed to low BRD. The percentage of low-BRD adolescents who experienced high CM was 31.4%, whereas 58% of high-BRD adolescents experienced high CM in SI. Adolescents with high BRD were more likely to experience high levels of CM in SP and SAs.
Adolescents at high risk of suicidal behavior in relation to CM should be targeted accordingly. Improving biological rhythm in adolescents who experience CM could help prevent them from engaging in suicidal behavior.
生物节律紊乱（BRD）对青少年期儿童虐待（CM）与自杀行为之间关联的影响尚不清楚。CM会增加自杀意念（SI）、自杀计划（SP）和自杀未遂（SA）的风险。关于CM对自杀行为影响的性别差异研究较少。目前尚不清楚这些影响是否会因BRD的不同水平而有所不同。
确定CM对自杀行为影响的性别差异，并研究在不同BRD水平下的这些影响。
该分析基于2019年10月至12月从中国三个城市招募的7986名青少年的数据。所有参与者年龄为14.7±2岁，填写了涉及CM、BRD和自杀行为的标准问卷。
共有22.9%、10.8%和4.7%的青少年报告在过去一年中有SI/SP/SA。当暴露于最高水平的CM时，女孩更有可能出现SI和SP；男孩比女孩更有可能出现SA。仅在暴露于低BRD的女孩中观察到中等水平的CM与SI/SP/SA之间存在显著关系。中等程度的CM仅与暴露于低BRD的男孩的SI显著相关。经历高CM的低BRD青少年比例为31.4%，而在SI中经历高CM的高BRD青少年比例为58%。BRD高的青少年在SP和SA中更有可能经历高水平的CM。
应针对与CM相关的自杀行为高风险青少年采取相应措施。改善经历CM的青少年的生物节律有助于防止他们出现自杀行为。
