背景:自我伤害,儿童和青少年严重的心理健康问题,全球患病率各不相同。先前的研究表明,这些人群中生物节律的特定行为方面与自我伤害风险之间存在潜在关联。
目的:我们的研究旨在使用宝兴青年心理健康(BYMH)队列阐明中国儿童和青少年的生物节律模式与自我伤害倾向之间的关系。
方法:我们纳入了来自BYMH队列的1883名中国儿童和青少年。用于评估生物节律和自我伤害的自我报告问题。我们应用主成分分析(PCA)来区分生物节律的模式。使用Logistic回归模型来估计生物节律之间的关联,以及生物节律模式和自我伤害的风险。
结果:在参与者中,35.0%报告经历过终身自我伤害。PCA揭示了六种显着的主要生物节律模式。自我伤害风险的增加与不健康的饮食习惯有关,白天的疲劳,和不健康的睡前零食。相反,强调体育锻炼的模式,家庭早餐,营养饮食表现出降低的自我伤害倾向。这些趋势在不同的自我伤害属性中持续存在,包括类型,最近,和自我伤害的频率。
结论:本研究强调了生物节律对中国青年自我伤害风险的关键影响。有针对性的生活方式干预,专注于改善睡眠和饮食习惯,可以作为有效的预防措施。我们的发现为未来的纵向研究奠定了基础,以进一步探索这些关联,促进创造量身定制的干预措施,以遏制自我伤害,提高年轻人群的心理健康。
BACKGROUND: Self-harm, a severe mental health concern among children and adolescents, has varying global prevalence rates. Previous studies have suggested potential associations between specific behavioral aspects of biological rhythm and self-harm risk in these populations.
OBJECTIVE: Our study aimed to elucidate the relationship between biological rhythm patterns and the propensity of self-harm among Chinese children and adolescents using the Baoxing Youth Mental Health (BYMH) cohort.
METHODS: We included 1883 Chinese children and adolescents from the BYMH cohort. The self-report questions used to assess biological rhythm and self-harm. We applied Principal Component Analysis (PCA) to distinguish patterns of biological rhythms. Logistic regression models were conducted to estimate the associations between biological rhythm, as well as biological rhythm patterns and risk of self-harm.
RESULTS: Of the participants, 35.0% reported experiencing lifetime self-harm. PCA revealed six significantly predominant biological rhythm patterns. Elevated risks of self-harm were linked with unhealthy eating practices, daytime tiredness, and unhealthy bedtime snacking. Conversely, patterns emphasizing physical exercise, family meals for breakfast, and nutritious diet exhibited decreased self-harm propensities. These trends persisted across varied self-harm attributes, including type, recency, and frequency of self-harm.
CONCLUSIONS: This study underscores the critical impact of biological rhythms on self-harm risks among Chinese youth. Targeted lifestyle interventions, focusing on improved sleep and dietary habits, could serve as potent preventive measures. Our findings lay the groundwork for future longitudinal studies to further probe these associations, fostering the creation of tailored interventions to curb self-harm and enhance mental well-being in younger populations.
