Abstract

AIM

This study was designed to determine the risk factors for acquiring campylobacter infection in Christchurch in the summer of 1992/3.

METHODS

A case control study was conducted of 100 cases and controls from urban areas matched for age and sex. Cases and controls were interviewed by telephone using a questionnaire and results analysed using the Epi Info statistical computer programme.

RESULTS

Eighty one percent of both cases and controls had recently consumed poultry. Eating poultry at a friends house (OR = 3.18, CI 1.0, 10.73, p = 0.03), at a barbecue (OR = 3.00, CI 0.99, 9.34, p = 0.03) or eating undercooked chicken (OR = 4.94, CI 1.03, 23.62, p = 0.05) was a risk whereas eating at home was protective (OR = 0.36, CI 0.14, 0.9, p = 0.02). Other factors associated with increased risk were drinking water from a nonurban supply (OR = 2.7, CI 0.89, 8.33, p = 0.09) or consumption of chicken bought fresh (OR = 1.8, CI 0.85, 3.82, p = 0.10).

CONCLUSION

Poorly cooked or handled chicken is a significant source of human campylobacter infection. Morbidity may be reduced by increased public awareness and improvement of cooking practices.

摘要

目的

本研究旨在确定1992/1993年夏季克赖斯特彻奇市弯曲杆菌感染的危险因素。

方法

对100例病例和来自市区的年龄和性别匹配的对照进行病例对照研究。通过电话使用问卷对病例和对照进行访谈，并使用Epi Info统计计算机程序分析结果。

结果

病例组和对照组中81%的人近期食用过家禽。在朋友家食用家禽（比值比=3.18，可信区间1.0，10.73，p=0.03）、在烧烤时食用（比值比=3.00，可信区间0.99，9.34，p=0.03）或食用未煮熟的鸡肉（比值比=4.94，可信区间1.03，23.62，p=0.05）是危险因素，而在家中食用则具有保护作用（比值比=0.36，可信区间0.14，0.9，p=0.02）。其他与风险增加相关的因素包括饮用来自非城市水源的水（比值比=2.7，可信区间0.89，8.33，p=0.09）或食用新鲜购买的鸡肉（比值比=1.8，可信区间0.85，3.82，p=0.10）。
