To determine whether parentally reported habitual intake of specific foods differed between children with diagnosed Campylobacter jejuni infection and children of a comparison group without diagnosed infection.
DESIGN, SETTING AND SUBJECTS: Information was collected from the parents or primary caregivers of South Australian children aged 1-5 years with diagnosed C. jejuni (cases, n=172) and an age- and gender-matched group of uninfected children (controls, n=173). Frequency of consumption of 106 food and drink items was determined for the preceding two months by food-frequency questionnaire. Four children in the control group had recorded diarrhoeal episodes during the assessment period and were excluded, so 169 responses were evaluated for this group. Information was gathered on possible confounders including socio-economic status. Response frequencies were classified into three levels of consumption (rarely, weekly or daily) and statistical comparison was made by frequency of consumption of foods versus the 'rarely' classification for cases and controls, respectively.
Frequency of consumption of most foods, including starchy foods and fruits and vegetables, did not differ between cases and controls. However, reported consumption of eight food items (block and processed cheese (slices and spread), salami/fritz (a form of processed sausage), chicken nuggets, pasteurised milk, fish (canned or fresh) and hot French fries) was significantly higher by controls.
The hypothesis that reported consumption of starchy foods was lower by cases than by controls was not supported by the data. However, consumption of some processed and unprocessed foods was higher by controls. Some of these foods have established bactericidal actions in vitro that may indicate a possible mechanism for this apparent protection.
确定确诊为空肠弯曲菌感染的儿童与未确诊感染的对照组儿童在父母报告的特定食物习惯性摄入量上是否存在差异。
设计、地点和研究对象：收集了南澳大利亚州1至5岁确诊为空肠弯曲菌感染儿童（病例组，n = 172）以及年龄和性别匹配的未感染儿童组（对照组，n = 173）的父母或主要照顾者的信息。通过食物频率问卷确定了前两个月106种食品和饮料的消费频率。对照组中有4名儿童在评估期间记录有腹泻发作，被排除在外，因此该组共评估了169份回复。收集了包括社会经济状况等可能的混杂因素信息。将回复频率分为三个消费水平（很少、每周或每天），并分别按病例组和对照组食物消费频率与“很少”类别进行统计比较。
大多数食物的消费频率，包括淀粉类食物、水果和蔬菜，病例组和对照组之间没有差异。然而，对照组报告的8种食物（块状和加工奶酪（切片和涂抹型）、意大利腊肠/弗里茨香肠（一种加工香肠）、鸡块、巴氏杀菌牛奶、鱼（罐装或新鲜）和热薯条）的消费量显著更高。
病例组淀粉类食物报告消费量低于对照组的假设未得到数据支持。然而，对照组一些加工和未加工食物的消费量更高。其中一些食物在体外已证实有杀菌作用，这可能表明了这种明显保护作用的一种潜在机制。
