This study aimed to establish if a significant relationship exists between sleep and aggression in a large representative adolescent cohort and explores the impact of potential confounders. This cross-sectional secondary data analysis included 10,866 males and females aged 13–15 years, from the UK-based 2015 Millenium Cohort Study (sixth sweep). Independent variables included self-report measures of sleep duration and quality. The parent reported ‘Strengths and Difficulties Questionnaire’ conduct score measured aggression. Binary logistic regression examined independent associations between each sleep variable and aggression. Multiple regression models then adjusted for potential confounders: age, sex, socioeconomic status, arousal, and affect. Under 8 hours of sleep on average was significantly associated with aggression when age, sex and income were controlled ( p = .008). This became insignificant following adjustment for both affect and arousal. Sleep quality remained significantly associated with aggression when all confounders were controlled: ‘sleep onset latency >30 minutes’ and ‘wakening at least a good bit of the time’ increased the odds of aggression by around 27.9% ( p < .001) and 43.5% respectively ( p < .001). A significant association exists between poor subjective sleep quality and heightened aggression in this cohort, when all our confounders are controlled, identifying sleep quality as a potential target in treating adolescent aggression.

探索青少年睡眠与攻击性之间的关系：利用英国千年队列研究进行的横断面研究

本研究旨在确定在大型代表性青少年群体中睡眠与攻击行为之间是否存在显着关系，并探讨潜在混杂因素的影响。这项横断面二次数据分析包括来自英国 2015 年千禧队列研究（第六次扫描）的 10,866 名 13-15 岁男性和女性。自变量包括睡眠持续时间和质量的自我报告测量。家长报告了“优势和困难问卷”行为分数，衡量了攻击性。二元逻辑回归检查了每个睡眠变量与攻击性之间的独立关联。然后，多元回归模型针对潜在的混杂因素进行了调整：年龄、性别、社会经济地位、觉醒和情感。当年龄、性别和收入受到控制时，平均睡眠不足 8 小时与攻击行为显着相关 (p = .008)。在对情感和唤醒进行调整后，这一点变得微不足道。当所有混杂因素都得到控制时，睡眠质量仍然与攻击行为显着相关：“入睡潜伏期 > 30 分钟”和“至少大部分时间醒来”使攻击行为的几率增加约 27.9% (p < .001) 和 43.5分别为 % (p < .001)。当我们控制所有混杂因素时，该队列中主观睡眠质量差和攻击性增强之间存在显着关联，将睡眠质量确定为治疗青少年攻击性的潜在目标。
