To look for an association between sleep deprivation and risk of accidental falls (AF) in children.
A questionnaire was applied to two groups of children aged 1-14 years, encompassing children observed in an emergency room for AF (G1) and children attending health care visits (HV) (G2). Collected data included demographic characteristics, medical history, previous week's sleep pattern (PWSP), sleep duration and sleep pattern in the preceding 24 h, mechanism of fall, and injury severity.
acute or chronic disease or exposure to drugs interfering with sleep. Statistical analyses included Fisher's exact test, Pearson Chi-square, Fisher-Freeman-Halton test, T and Mann-Whitney tests for independent samples, and multivariate logistic regression (α=5%).
We obtained 1756 questionnaires in G1 and 277 in G2. Of those, 834 in G1 and 267 in G2 were analyzed. We found an increased risk of AF in boys (OR 1.6; 95% CI 1.2-2.4). After controlling for age, gender, summer holidays, parental education and profession, lack of naps and PWSP were associated with increased risk (OR 2.1; 95% CI 1.3-3.3 and OR 2.7; 95% CI 1.2-6.1). In 3-5 year-old children there was an association between AF and a shorter than usual sleep duration in the previous 24 h (p=0.02).
To our knowledge, our study is the largest so far to assess the association between sleep deprivation and childhood injury. It evidences a protective effect of naps in children. Sleep duration of less than 8 h increases risk of AF. Pre-schoolers may be particularly susceptible to sleep deprivation.
寻找儿童睡眠剥夺与意外跌倒（AF）风险之间的关联。
对两组年龄在 1-14 岁的儿童进行问卷调查，包括在急诊室观察到的因 AF 就诊的儿童（G1 组）和接受保健就诊的儿童（G2 组）。收集的数据包括人口统计学特征、病史、前一周的睡眠模式（PWSP）、前 24 小时的睡眠持续时间和模式、跌倒机制以及伤害严重程度。
急性或慢性疾病或接触干扰睡眠的药物。统计分析包括 Fisher 确切检验、Pearson Chi-square 检验、Fisher-Freeman-Halton 检验、T 检验和 Mann-Whitney 检验（独立样本）以及多变量逻辑回归（α=5%）。
G1 组获得 1756 份问卷，G2 组获得 277 份。其中，G1 组 834 份，G2 组 267 份进行了分析。我们发现男孩 AF 风险增加（OR 1.6；95%CI 1.2-2.4）。在控制年龄、性别、暑假、父母教育和职业、缺乏午睡和 PWSP 后，与风险增加相关（OR 2.1；95%CI 1.3-3.3 和 OR 2.7；95%CI 1.2-6.1）。在 3-5 岁儿童中，AF 与前 24 小时睡眠持续时间较短有关（p=0.02）。
据我们所知，我们的研究是迄今为止评估儿童睡眠剥夺与损伤之间关联的最大研究。它证明了午睡对儿童的保护作用。睡眠持续时间少于 8 小时会增加 AF 的风险。学龄前儿童可能特别容易受到睡眠剥夺的影响。
