To compare sleep/wake patterns in children born preterm in Australia vs Canada and determine cultural differences in the relationship between parental perception of sleep and actual sleep behaviors.
Australian and Canadian children born preterm were recruited from the Caffeine for Apnea of Prematurity trial (n = 188, 5-12 y) and underwent 14 days actigraphy monitoring. Parents completed the National Sleep Foundation 2004 Sleep in America questionnaire. Cross-cultural differences in sleep characteristics assessed by actigraphy and parent-reported questionnaire were examined. Correlational analyses determined the associations between parental perceptions of child sleep need and sleep behavior.
Actigraphy showed preterm children obtained, on average, 8 h sleep/night, one hour less than population recommendations for their age. There was no difference in total sleep time (TST) between Australian and Canadian cohorts; however, bed and wake times were earlier in Australian children. Bedtimes and TST varied by 60 minutes from night to night in both cohorts. Parent-reported child TST on the National Sleep Foundation questionnaire was 90 minutes longer than recorded by actigraphy. Both bedtime and TST on weekdays and weekends were related to parental perception of child sleep need in the Australian cohort. Only TST on weekdays was related to parental perception of child sleep need in the Canadian cohort.
This study suggests that short sleep duration and irregular sleep schedules are common in children born preterm. Cultural differences in the association between parental perception of child sleep need and actual sleep behaviors provide important targets for future sleep health education.
比较澳大利亚和加拿大早产儿童的睡眠/觉醒模式，并确定父母对睡眠的认知与实际睡眠行为之间关系的文化差异。
从“咖啡因治疗早产呼吸暂停试验”中招募澳大利亚和加拿大的早产儿童（n = 188，5 - 12岁），并进行14天的活动记录仪监测。父母完成了美国国家睡眠基金会2004年的美国睡眠调查问卷。研究了通过活动记录仪和父母报告问卷评估的睡眠特征的跨文化差异。相关性分析确定了父母对儿童睡眠需求的认知与睡眠行为之间的关联。
活动记录仪显示，早产儿童平均每晚睡眠8小时，比其年龄组的推荐睡眠时间少1小时。澳大利亚和加拿大队列的总睡眠时间（TST）没有差异；然而，澳大利亚儿童的上床睡觉时间和起床时间更早。两个队列中，每晚的上床睡觉时间和TST相差60分钟。父母在美国国家睡眠基金会问卷上报告的儿童TST比活动记录仪记录的长90分钟。在澳大利亚队列中，工作日和周末的上床睡觉时间和TST都与父母对儿童睡眠需求的认知有关。在加拿大队列中，只有工作日的TST与父母对儿童睡眠需求的认知有关。
本研究表明，睡眠时间短和睡眠时间表不规律在早产儿童中很常见。父母对儿童睡眠需求的认知与实际睡眠行为之间关联的文化差异为未来的睡眠健康教育提供了重要目标。
