BACKGROUND
In developed countries, gastrointestinal illness (GI) is typically mild and self-limiting, however, it has considerable economic impact due to high morbidity.
METHODS
The magnitude and distribution of acute GI in British Columbia (BC), Canada was evaluated via a cross-sectional telephone survey of 4,612 randomly selected residents, conducted from June 2002 to June 2003. Respondents were asked if they had experienced vomiting or diarrhoea in the 28 days prior to the interview.
RESULTS
A response rate of 44.3% was achieved. A monthly prevalence of 9.2% (95% CI 8.4-10.0), an incidence rate of 1.3 (95% CI 1.1-1.4) episodes of acute GI per person-year, and an average probability that an individual developed illness in the year of 71.6% (95% CI 68.0-74.8), weighted by population size were observed. The average duration of illness was 3.7 days, translating into 19.2 million days annually of acute GI in BC.
CONCLUSION
The results corroborate those from previous Canadian and international studies, highlighting the substantial burden of acute GI.
背景
在发达国家，胃肠道疾病（GI）通常症状较轻且具有自限性，然而，由于其高发病率，它具有相当大的经济影响。
方法
通过对2002年6月至2003年6月期间随机抽取的4612名加拿大不列颠哥伦比亚省（BC）居民进行横断面电话调查，评估该省急性胃肠道疾病的严重程度和分布情况。询问受访者在访谈前28天内是否经历过呕吐或腹泻。
结果
实现了44.3%的回复率。观察到每月患病率为9.2%（95%置信区间8.4 - 10.0），每人每年急性胃肠道疾病发病率为1.3次（95%置信区间1.1 - 1.4），按人口规模加权后，个体在一年内患病的平均概率为71.6%（95%置信区间68.0 - 74.8）。疾病的平均持续时间为3.7天，这意味着BC省每年急性胃肠道疾病的患病天数达1920万天。
结论
结果证实了加拿大此前及国际研究的结果，突出了急性胃肠道疾病的沉重负担。
