背景包括日本在内的亚洲国家的学龄前儿童夜间睡眠时间比欧洲和美国的儿童要短。我们研究了夜间睡眠时间对日本儿童早期行为发育的影响。方法我们使用了2001年开始的一项大规模的日本全国性、基于人群的纵向调查的数据。我们将研究参与者限制在怀孕37周后出生的儿童，出生体重为≥ 2500 g和单胎出生(n=41 890)。夜间睡眠时间为2.5 岁。对关于5.5岁 年龄适龄行为的调查问题的回答被用作行为发展的指标。结果夜间睡眠≥9 h与听不清坐立不安和无法保持耐心的优势比分别为1.2 6(95%可信区间，1.14~1.3 9)和1.2 7(1.16~1.3 8)。夜间睡眠时间不规律的儿童与年龄相适应的行为障碍有关。在通常和有时午睡的儿童中，根据午睡频率，这些结果与分层前相似。结论夜间睡眠时间短尤其影响多动和冲动。不规律的夜间睡眠时间比短睡眠时间更会增加执行与年龄相适应的整体行为的能力。确保儿童早期有规律和充足的夜间睡眠时间对于健康的行为发展很重要。
BackgroundPreschool children in Asian countries, including Japan, sleep for a shorter duration at night than those in Europe and the USA. We examined the effects of the nighttime sleep duration on behavioral development in early childhood in Japan.MethodsWe used data from a large Japanese nationwide, population‐based, longitudinal survey that began in 2001. We restricted the study participants to children born after 37 gestational weeks, with a birth weight ≥ 2500 g and singleton births (n= 41 890). The nighttime sleep duration was examined at 2.5 years old. Responses to survey questions regarding age‐appropriate behavior at 5.5 years old were used as indicators of behavioral development. We conducted logistic regression analyses with adjustment for confounding factors, with ≥11 h of nighttime sleep as the reference group.ResultsThe odds ratios for children who had ≤9 h of nighttime sleep, which was associated with being unable to listen with fidgeting and being unable to remain patient, were 1.26 (95% confidence interval, 1.14–1.39) and 1.27 (1.16–1.38), respectively. Children who had an irregular nighttime sleep duration were associated with age‐appropriate behavioral inabilities. These results were similar in children who usually and sometimes took naps to those before stratification by the frequency of napping.ConclusionA short nighttime sleep duration especially affects hyperactivity and impulsivity. An irregular nighttime sleep duration increases the inability to perform overall age‐appropriate behaviors more than a short sleep duration. Ensuring a regular and sufficient nighttime sleep duration in early childhood is important for healthy behavioral development.
