确定与肠道疾病发病率相关的县级社会人口和经济因素可能为这些疾病的社区传播动态以及预防机会提供新的见解。我们使用来自国家法定疾病监测系统、美国人口普查局和卫生资源与服务管理局的数据，对1993年至2002年期间美国各县与沙门氏菌病、志贺氏菌病和大肠杆菌O157:H7感染发生率相关的26个社会人口统计学和经济因素进行了生态学分析。我们的研究表明，种族、民族、居住地、年龄、教育程度和贫困可能影响获得这些肠道细菌疾病之一的风险。关于沙门氏菌和志贺氏菌血清型的信息缺乏特异性，可能导致社区水平决定因素与报告的这些疾病发病率之间的关联不太具体。未来的生态分析应使用血清型特异性发病率数据，这些数据可从实验室监测系统获得。
Identifying county-level sociodemographic and economic factors associated with the incidence of enteric disease may provide new insights concerning the dynamics of community transmission of these diseases as well as opportunities for prevention. We used data from the National Notifiable Diseases Surveillance System, the U.S. Census Bureau, and the Health Resources and Services Administration to conduct an ecological analysis of 26 sociodemographic and economic factors associated with the incidence of salmonellosis, shigellosis, and E. coli O157:H7 infections in US counties for the period 1993 to 2002. Our study indicates that race, ethnicity, place of residence, age, educational attainment, and poverty may affect the risk of acquiring one of these enteric bacterial diseases. The lack of specificity of information regarding salmonellae and shigellae serotypes may have led to less specific associations between community-level determinants and reported incidence of those diseases. Future ecological analyses should use serotype-specific data on incidence, which may be available from laboratory-based surveillance systems.
