目的：（1）通过比较睡眠日记和活动记录来检查低收入样本中的幼儿睡眠，（2）评估幼儿是否符合国家睡眠基金会的建议（11-14小时睡眠/24小时和晚上9点前就寝）。方法：从2个服务于低收入社区的卫生保健站招募方便样本的母亲-幼儿二对。活动记录仪被放置在蹒跚学步的孩子的脚踝上，并佩戴了3天3夜。母亲们同时完成了睡眠日记。通过这两种方法收集就寝时间、夜间睡眠时间、午睡时间和24小时睡眠时间。使用制造商的评分算法和手动编辑的组合来分析活动描记数据。进行描述性统计和配对样本t检验，以检查睡眠日记和活动记录仪的睡眠估计值之间的差异。结果：20名幼儿（年龄13-42个月）被纳入分析。根据腕动记录，1名幼儿在所有3个晚上都在晚上9点前上床睡觉。6名幼儿在3天中的1天内实现了11至14小时的睡眠，但当睡眠在整个研究中平均时，没有一个达到这个目标。与体动记录相比，睡眠日记低估了就寝时间1小时，高估了夜间睡眠时间2.5小时，高估了24小时睡眠时间2.3小时，平均所有3个晚上。结论：母亲报告显着更早的就寝时间和更长的睡眠持续时间为他们的幼儿相比，活动，这表明客观的措施不同，从睡眠日记在评估低收入家庭的幼儿睡眠。研究结果不应未经复制就推广到低收入家庭人群。
Objectives: (1) To examine toddler sleep in a low-income sample by comparing sleep diaries and actigraphy and (2) to assess whether toddlers are meeting the National Sleep Foundation recommendations (11-14 hours of sleep/24 hours and bedtime before 9 PM). Methods: A convenience sample of mother-toddler dyads was recruited from 2 health care sites serving low-income communities. An actigraph was placed on the toddler's ankle and was worn for 3 days and nights. Mothers concurrently completed a sleep diary. Bedtime, nighttime sleep duration, nap duration, and 24-hour sleep duration were collected by both measures. Actigraphy data were analyzed using a combination of manufacturer's scoring algorithm and manual editing. Descriptive statistics and paired samples t-tests were conducted to examine the differences between sleep estimates by a sleep diary and actigraphy. Results: Twenty toddlers (aged 13-42 months) were included in the analyses. Based on actigraphy, 1 toddler went to bed by 9 PM on all 3 nights. Six toddlers achieved 11 to 14 hours of sleep measured in a 24-hour period for 1 of the 3 days, but when sleep was averaged across the study, none achieved this goal. Compared with actigraphy, sleep diaries underestimated bedtime by 1 hour, overestimated nighttime sleep duration by 2.5 hours, and overestimated 24-hour sleep duration by 2.3 hours, on average for all 3 nights. Conclusion: Mothers reported significantly earlier bedtimes and longer sleep durations for their toddlers compared with actigraphy, suggesting that objective measures differ from sleep diaries in assessing sleep in toddlers from low-income families. Findings should not be generalized to populations of low-income families without replication.
