目的：儿童哮喘和超重/肥胖（OV/OB）经常同时发生，患有这两种疾病的青少年表现出不良的睡眠/就寝习惯。本研究评估了有/无哮喘共病的OV/OB青少年每周至周末就寝/清醒时间变异性的差异，并测试了变异性是否能预测工作日的睡眠。（n= 142; 28%共病哮喘; 7-12岁）佩戴加速计5天（2个周末），提供周到周末的就寝时间/唤醒时间变化、工作日总睡眠时间（TST）、工作日床上时间（TIB），结果：OV/OB+哮喘组除家庭收入较低外，两组间无人口统计学差异。OV/OB+哮喘组显示工作日（平均OV/OB+哮喘= 10：39 pm，平均OV/OB仅= 10：30 pm）和周末（平均OV/OB+哮喘= 11：41 pm，平均OV/OB仅= 11：17 pm）就寝时间较晚，工作日唤醒时间较早（平均OV/OB+哮喘= 6：40 am，平均OV/OB仅= 6：51 am），周末唤醒时间相似（平均OV/OB+哮喘= 7：54 pm，平均OV/OB仅= 7：52 pm）。单变量MANOVA随访表明哮喘组的主要影响是周至周末的就寝时间和清醒时间变异性，OV/OB+哮喘组的就寝时间（OV/OB+哮喘平均值= 90分钟）和清醒时间（OV/OB+哮喘平均值= 108分钟）变异性增加约30分钟。在OV/OB+哮喘组中，更大的觉醒时间变异性预示着工作日TIB和WASO的分钟数更少。在OV/OB组内，清醒时间变异性预测工作日TIB.Conclusion分钟数较少：研究结果表明，哮喘状态赋予更多的风险，目前OV/OB青年之间的一周到周末的变异性，更大的变异性缩短了工作日的睡眠时间。需要进一步研究哮喘患者周与周末睡眠差异较大的原因。
Objective: Pediatric asthma and overweight/obesity (OV/OB) frequently co-occur and youth with both conditions exhibit poor sleep/bedtime habits. This study assessed differences in week-to-weekend bedtime/wake time variability among OV/OB youth with/without comorbid asthma, and tested whether variability predicted weekday sleep.Methods: OV/OB youth (n= 142; 28% comorbid asthma; 7–12 years) wore an Accelerometer for 5 days (2 weekend days), providing estimates of week-to-weekend bedtime/wake-time variability, weekday Total Sleep Time (TST), weekday time in bed (TIB), and weekday wake after sleep onset (WASO).Results: There were no demographic differences between groups beyond lower family income for the OV/OB+asthma group. The OV/OB+asthma group exhibited later weekday (mean OV/OB+asthma = 10:39 pm, mean OV/OB only = 10:30pm) and weekend (mean OV/OB+asthma = 11:41 pm, mean OV/OB only = 11:17pm) bedtimes, earlier weekday waketimes (mean OV/OB+asthma = 6:40 am, mean OV/OB only = 6:51 am), and similar weekend waketimes (mean OV/OB+asthma = 7:54 pm, mean OV/OB only = 7:52 pm. Univariate MANOVA follow-ups indicated a main effect of asthma group for week-to-weekend bedtime and waketime variability, with the OV/OB+asthma group evidencing approximately 30 minutes greater bedtime (OV/OB+asthma mean = 90 minutes) and waketime (OV/OB+asthma mean = 108 minutes) variability. Within the OV/OB+asthma group, greater waketime variability predicted fewer minutes of weekday TIB and WASO. Within the OV/OB only group, wake time variability predicted fewer minutes of weekday TIB.Conclusion: Findings suggest that asthma status confers risk for more week-to-weekend variability among currently OV/OB youth, and that greater variability shortens the weekday sleep period. Further research on reasons for greater week-to-weekend sleep variability in asthma is needed.
