导读：影响美国学龄儿童的两个问题是睡眠不足和肥胖的日益流行。本研究的目的是量化与媒体相关的技术使用和咖啡因摄入，以评估它们对儿童睡眠时间和体重指数（BMI）的潜在影响。方法：该研究是对来自美国国家睡眠基金会睡眠民意调查的6至10岁儿童（N = 625）的二次分析。回归分析用于评估咖啡因与技术使用、睡眠变量和BMI之间的关系，并对年龄、种族、性别和一般健康状况进行了调整。结果：近30%（29.5%）的儿童每天饮用含咖啡因的饮料，42.4%的儿童卧室里有电视。喝含咖啡因饮料的儿童每晚睡眠时间比不喝含咖啡因饮料的儿童少15分钟（b = -0.27, p = 0.002）。卧室里有三件科技产品的孩子比卧室里没有科技产品的孩子少睡45分钟（b = -0.75, p = 0.010）。在调整变量后，只有饮用含咖啡因的饮料与BMI z分有关。讨论：咖啡因摄入与使用科技产品缩短睡眠时间和增加BMI之间的复杂关系需要进一步研究。未来的研究应该探索如何在年轻人群中改变这些导致睡眠时间缩短的风险因素。J儿科保健。（2012） 26, 276-282。
Introduction: Two problems affecting school-aged children in the United States are inadequate sleep and an increased prevalence of obesity. The purpose of this study was to quantify media-related technology use and caffeine consumption in order to assess their potential effects on sleep duration and body mass index (BMI) in children.Methods: The study was a secondary analysis of children 6 to 10 years of age (N = 625) from the National Sleep Foundation's Sleep in America Poll. Regression analysis was used to assess the relationship between caffeine and technology use, sleep variables, and BMI, adjusting for age, race, gender, and general health.Results: Almost 30% (29.5%) of the children consumed a daily caffeinated beverage, and 42.4% had a television in the bedroom. Children who drank caffeinated beverages had 15 fewer minutes of sleep per night than did children who did not drink such beverages (b = -0.27, p = .002). Children with three technology items in their bedroom received 45 fewer minutes of sleep than did children without these items in their bedroom (b = -0.75, p = .010). Having adjusted for variables, only drinking caffeinated beverages was associated with a BMI z score.Discussion: The complex relationships between caffeine intake and the use of technology with shortened periods of sleep and increased BMI need further study. Future research should explore how these risk factors for shortened periods of sleep can be modified in this young population. J Pediatr Health Care. (2012) 26, 276-282.
