Short sleep duration has been linked to higher levels of aggression. To synthetize all available research on this association, a systematic review and meta-analysis was performed. We included observational and experimental studies, using various measures of sleep duration and aggression. Eighty eligible papers were identified, describing 82 studies comprising a total number of 76.761 participants. Meta-analysis of results was possible for 60 studies. Pooled observational results on the association between sleep duration and aggression showed a correlation estimate of -0.16 (95%CI -0.19, -0.12; I = 83.9%) and an odds ratio estimate of 1.83 (95%CI 1.47, 2.28; I = 0.0%). For experimental studies, the pooled Standardized Mean Difference after manipulation of sleep duration was -0.37 (95%CI -0.80, 0.05; I = 89.05%) for controlled designs and -0.34 (95%CI -0.54, -0.14; I = 89.05%) for pre-post designs. Effect estimates were stronger for individuals with psychological vulnerabilities and younger persons. Exclusion of studies with low methodological quality strengthened the effect estimate in experimental but not in observational studies. To conclude, short sleep duration is associated with higher levels of aggression, with observational research strongly supporting the association and experimental studies providing mixed results. More well-designed prospective and experimental studies are needed to establish causality and optimize treatment, especially for individuals with psychological vulnerabilities.
睡眠时长较短与攻击性增强有关。为了综合所有关于这一关联的现有研究，我们进行了一项系统综述和荟萃分析。我们纳入了观察性和实验性研究，采用了各种睡眠时长和攻击性的测量方法。共识别出80篇符合条件的论文，描述了82项研究，总计76761名参与者。60项研究的结果可以进行荟萃分析。关于睡眠时长与攻击性之间关联的汇总观察结果显示，相关系数估计值为-0.16（95%置信区间为-0.19，-0.12；I² = 83.9%），优势比估计值为1.83（95%置信区间为1.47，2.28；I² = 0.0%）。对于实验性研究，在控制设计中，睡眠时长调整后的汇总标准化均差为-0.37（95%置信区间为-0.80，0.05；I² = 89.05%），在前测-后测设计中为-0.34（95%置信区间为-0.54，-0.14；I² = 89.05%）。对于有心理脆弱性的个体和年轻人，效应估计更强。排除方法学质量较低的研究后，实验性研究中的效应估计得到了加强，但观察性研究中没有。总之，睡眠时长较短与较高水平的攻击性有关，观察性研究有力地支持了这一关联，而实验性研究则提供了混合结果。需要更多设计良好的前瞻性和实验性研究来确定因果关系并优化治疗，尤其是对于有心理脆弱性的个体。
