The National Studies on Acute Gastrointestinal Illness (NSAGI) initiative was designed to generate baseline period prevalence rates of self-reported AGI in communities across Canada, assess the burden associated with AGI, and quantify the under-reporting of AGI in Canada's national enteric disease reporting systems.
Methods utilized included population surveys administered randomly via telephone services. Three population surveys in three locations within Canada included over 10,000 residents. Questions pertained to recent symptoms as well as socio-demographic factors, use of the health care system and missed work or school due to illness.
In summary of published results, there are an estimated 1.3 episodes of AGI per person-year and an estimated 10-47, 13-37 and 23-49 cases in the community for every case of verotoxigenic Escherichia coli, Salmonella and Campylobacter, respectively, captured within the national surveillance system. AGI represents an annual per capita cost of $115 CAD.
The work of NSAGI highlights the significant burden and impact of AGI in the Canadian population. These results will also be incorporated into the current work at the World Health Organization (WHO) to estimate the global burden of food related illnesses.
全国急性胃肠疾病研究（NSAGI）倡议旨在得出加拿大各社区自我报告的急性胃肠疾病（AGI）的基线期间患病率，评估与AGI相关的负担，并量化加拿大国家肠道疾病报告系统中AGI报告不足的情况。
所采用的方法包括通过电话服务随机进行的人口调查。在加拿大境内三个地点开展的三项人口调查涵盖了超过10,000名居民。问题涉及近期症状以及社会人口学因素、医疗保健系统的使用情况以及因病缺勤或缺课情况。
在已发表结果的总结中，估计每人每年有1.3次AGI发作，并且在国家监测系统中每发现1例产志贺毒素大肠杆菌、沙门氏菌和弯曲杆菌病例，社区中分别估计有10 - 47例、13 - 37例和23 - 49例AGI病例。AGI的人均年度成本为115加元。
NSAGI的工作凸显了AGI在加拿大人群中的重大负担和影响。这些结果还将纳入世界卫生组织（WHO）目前的工作中，以估计与食物相关疾病的全球负担。
