Abstract：
OBJECTIVE: Sleep duration and bedtime may play a role in children\'s cardiometabolic health, but research is lacking. This study examined associations between sleep patterns and cardiometabolic risk factors in Swedish nine-year-olds.
METHODS: This cross-sectional study used data from three studies, where identical outcome measures were conducted in 411 nine-year-olds, 51% boys, between 2016 and 2020. Sleep was assessed with wrist-worn accelerometers and sleep journals. Children were grouped based on meeting the sleep guidelines of 9-11 h and going to bed early or late based on the median bedtime. Analysis of covariance was used to examine associations between sleep patterns and cardiometabolic risk factors.
RESULTS: Meeting sleep guidelines and going to bed early were associated with lower metabolic syndrome score (-0.15 vs. 0.42, p = 0.029), insulin resistance (0.30 vs. 0.60, p = 0.025) and insulin levels (6.80 vs. 8.87 mIU/L, p = 0.034), compared with their peers who did not meet the guidelines and went to bed later. When adjusting for total sleep time, analyses still showed associations with the metabolic syndrome score (-0.19 vs. 0.50, p = 0.011).
CONCLUSIONS: The findings indicate that good sleep patterns could help mediate positive overall cardiometabolic health in children.

摘要：
目的：睡眠时间和就寝时间可能在儿童心脏代谢健康中起作用，但缺乏研究。这项研究调查了瑞典9岁儿童的睡眠模式与心脏代谢危险因素之间的关联。
方法：这项横断面研究使用了三项研究的数据，在411名9岁儿童中进行了相同的结果测量，51%的男孩2016年至2020年。使用手腕佩戴的加速度计和睡眠日志评估睡眠。根据满足9-11小时的睡眠指南对儿童进行分组，并根据中位就寝时间早睡或晚睡。协方差分析用于检查睡眠模式与心脏代谢危险因素之间的关联。
结果：符合睡眠指南和早睡与较低的代谢综合征评分相关（-0.15vs.0.42，p=0.029)，胰岛素抵抗（0.30vs.0.60，p=0.025）和胰岛素水平（6.80vs.8.87mIU/L，p=0.034),与那些不符合指导方针并稍后上床睡觉的同龄人相比。调整总睡眠时间时，分析仍显示与代谢综合征评分相关(-0.19vs.0.50,p=0.011)。
结论：研究结果表明，良好的睡眠模式有助于调节儿童的总体心脏代谢健康。
