A controlled trial has been carried out to test the widely held "clinical impression" that overweight infants have a greater liability to respiratory infections than those of normal weight. Two matched groups of children aged between 3 months and 2 years were studied, containing children whose weight was above the 90th percentile, or was between the 25th and 75th percentiles, at the start of the trial.Data from 120 children of the overweight group were available for analysis, of whom 47 experienced at least one respiratory infection during the trial and 73 did not. Of children remaining over the 90th percentile at the end of the trial 19 had suffered respiratory infections and 28 had not. One baby in the overweight group suffered a "cot death" from acute bronchiolitis. In the control group, 103 cases were analysed-23 had suffered a respiratory infection and 80 had remained free of respiratory infection throughout the trial. These figures are statistically significant and suggest that obesity in infants and young children is associated with an increased incidence of acute respiratory infections.
一项对照试验已开展，以检验一种广泛存在的“临床印象”，即超重婴儿比正常体重婴儿更易患呼吸道感染。研究了两组年龄在3个月至2岁之间相匹配的儿童，一组儿童在试验开始时体重高于第90百分位数，另一组体重在第25至75百分位数之间。超重组120名儿童的数据可供分析，其中47名儿童在试验期间至少经历了一次呼吸道感染，73名儿童未经历。试验结束时仍处于第90百分位数以上的儿童中，19名曾患呼吸道感染，28名未患。超重组中有一名婴儿因急性细支气管炎发生“婴儿猝死”。在对照组中，分析了103例病例，其中23例曾患呼吸道感染，80例在整个试验期间未患呼吸道感染。这些数字具有统计学意义，表明婴幼儿肥胖与急性呼吸道感染发病率增加有关。
