目的：胃食管反流的发病与多种因素有关，其中不良饮食习惯是重要的诱发因素之一。该文试图通过分析夜间食管pH检测的各项参数，探讨睡前进食对夜间胃食管反流的影响。方法：进行24 h胃食管反流监测的38例患儿，根据睡前2 h内是否进食分为进食组（A组n=16），未进食组(B组，n=22)。比较两组夜间反流次数、最长反流时间、持续时间>5 min的反流次数和pH<4的时间百分比。结果：A，B两组各项检测参数分别为①夜间总反流次：32（21.5-43.5） 和24（15-37.3）次；②最长反流时间：6.6( 2.4-29.8) min和4.5(2.5-13.2） min；③持续时间>5 min的反流次数：1.5( 0-3)和0（0-3）次； ④ pH<4的时间百分比：4.3%(2.1%-15.0%)和4.1%（2.0%-7.2%），两组比较均 P>0.05，差异均无显著性。结论：睡前非刺激性饮食对夜间反流无明显作用。［中国当代儿科杂志，2007，9（3）：207-209］

OBJECTIVE: An unhealthy food consumption habit attributes to one of the etiology of gastro-esophageal reflux. The purpose of this article was to study the influence of food intake before going to bed on the nighttime gastro-esophageal reflux. METHODS: hirty-eight children with upper gastrointestinal symptoms were divided into two groups on the basis of taking (Group A, n=16) or not taking (Group B, n=22) food (non-stimulating) within 2 hrs before going to bed. All of them underwent 24 hr esophageal pH monitoring. The times of reflux episode, the longest duration of reflux, the times of reflux duration >5 min, and the percentage of time of pH<4 were compared between the two groups. RESULTS: There were no significant differences in the parameters of pH monitoring between Groups A and B, with the times of reflux episode of 32 (21.5-43.5) vs 24 (15-37.3) , the longest duration of reflux of 6.6 ( 2.4-29.8) min vs 4.5 (2.5-13.2) min, the times of reflux episode longer than 5 min of 1.5 ( 0-3) vs 0 (0-3), and the percentage of time of pH < 4 of 4.3 (2.1-15.0)% vs 4.1 (2.0-7.2)% . CONCLUSIONS: Non-stimulating food intake before going to bed did not adversely affect the nighttime gastro-esophageal reflux.［Chin J Contemp Pediatr, 2007, 9 (3):207-209］
