导读：周末睡过头或补觉在儿童中很常见，但有关其对体重和血压影响的数据相对较少。这项研究的目的是评估青少年睡眠时间、睡过头、体重和血压之间的关系。方法：分析在图森儿童睡眠呼吸暂停评估研究（TuCASA）的两个检查周期中进行多导睡眠图检查的327名儿童（51.4%为男孩，平均年龄13.3±1.7岁）的睡眠时间、体重和血压。在上学的晚上和非上学的晚上的睡眠时间分别用于计算儿童和家长报告的总体睡眠时间的加权平均值。睡过头被定义为自己和父母报告的周末睡眠和工作日睡眠的差异。研究人员计算了总体睡眠时间、在校和非在校晚上的睡眠时间、睡得过多、血压、标准化体重指数（BMI）、打鼾、呼吸障碍指数（RDI）和年龄之间的简单相关性。然后使用显著的双变量关联来开发多变量偏相关模型。结果：父母在第一次考试时报告的总睡眠时间，父母和孩子报告的总睡眠时间和学校夜间睡眠时间，以及父母在第二次考试时报告的非学校夜间睡眠时间与BMI存在未调整的负相关。此外，对于BMI，两次检查周期的对数RDI与第二次检查周期的打鼾均观察到正相关。对于血压，年龄、父母报告的睡过头、咖啡因摄入和打鼾呈正相关。此外，对于血压，在第一次考试周期中，父母报告的总睡眠时间呈负相关，在第二次考试周期中，父母和孩子报告的总睡眠时间和学校夜间睡眠时间呈负相关。偏相关研究发现，BMI与父母第一次和第二次体检时报告的总睡眠时间呈负相关，与两次体检时的打鼾和log RDI呈正相关。收缩压只与年龄和打鼾有关。舒张压与年龄和咖啡因摄入量呈正相关，与家长报告的总睡眠时间和学校夜间睡眠时间负相关。睡过头和儿童报告的睡眠时间在这些模型中都没有体现。结论：睡眠不足，尤其是在校期间，与体重和血压升高有关。睡过头与体重和血压都没有关系。
INTRODUCTION: Weekend oversleep or catchup sleep is a frequent occurrence in children, but there are relatively little data concerning its impact on weight and blood pressure. The aim of this study was to assess the association between sleep duration and oversleep, and weight and blood pressure in adolescents.METHODS: Sleep duration, weight and blood pressure of 327 children (51.4% boys, mean age 13.3 ± 1.7 years) who had polysomnograms performed during both exam cycles of the Tucson Children's Assessment of Sleep Apnea study (TuCASA) were analyzed. Sleep duration on school nights and non-school nights was used to compute a weighted average of child and parent reported overall sleep duration respectively. Oversleep was defined as the difference between self and parent reported weekend sleep and weekday sleep separately. Simple correlations between overall sleep duration, sleep on school and non-school nights and oversleep, and blood pressure, standardized body mass index (BMI), snoring, respiratory disturbance index (RDI) and age were calculated. Significant bivariate associations then were used to develop multivariate partial correlation models.RESULTS: Unadjusted negative correlations with BMI were noted for parent reported total sleep duration at the 1st exam cycle, parent and child reported total sleep and school night sleep duration, and parent reported non-school night sleep duration at the 2nd exam cycle. Additionally, for BMI, positive correlations were observed for log RDI at both exam cycles and snoring at the 2nd exam cycle. For blood pressure, there were positive associations with age, parent reported oversleep, caffeine consumption and snoring. Additionally, for blood pressure, negative relationships were observed with parent reported total sleep duration at the 1st exam cycle, and parent and child reported total sleep and school night sleep durations at the 2nd exam cycle. Partial correlations found that BMI was negatively correlated with parent reported total sleep duration at the 1st exam cycle and parent reported total sleep duration at the 2nd exam cycle, and positively correlated with snoring and log RDI at both exam cycles. Systolic blood pressure was only associated with age and snoring. Diastolic blood pressure was positively correlated with age and caffeine consumption, and negatively correlated with parent reported total and school night sleep duration. Oversleep and child reported sleep duration were not represented in any of these models.CONCLUSION: Lower amounts of sleep especially on school nights is associated with higher body weight and blood pressure. Oversleep was not associated with either body weight or blood pressure.
