Abstract：
Salmonella is estimated to be the leading bacterial cause of U.S. domestically acquired foodborne illness. Large outbreaks of Salmonella attributed to ground beef have been reported in recent years. The demographic and sociodemographic characteristics of infected individuals linked to these outbreaks are poorly understood. We employed a retrospective case-control design; case-patients were people with laboratory-confirmed Salmonella infections linked to ground beef-associated outbreaks between 2012 and 2019, and controls were respondents to the 2018-2019 FoodNet Population Survey who reported eating ground beef and denied recent gastrointestinal illness. We used county-level CDC/ATSDR Social Vulnerability Index (SVI) to compare case-patient and controls. Case-patient status was regressed on county-level social vulnerability and individual-level demographic characteristics. We identified 376 case-patients and 1,321 controls in the FoodNet sites. Being a case-patient was associated with increased overall county-level social vulnerability (OR: 1.21 [95% CI: 1.07-1.36]) and socioeconomic vulnerability (OR: 1.24 [1.05-1.47]) when adjusted for individual-level demographics. Case-patient status was not strongly associated with the other SVI themes of household composition and disability, minority status and language, and housing type and transportation. Data on individual-level factors such as income, poverty, unemployment, and education could facilitate further analyses to understand this relationship.
摘要：
据估计，沙门氏菌是美国国内获得的食源性疾病的主要细菌原因。近年来，据报道，由于碎牛肉引起的沙门氏菌大规模爆发。与这些疫情有关的感染者的人口统计学和社会人口学特征知之甚少。我们采用回顾性病例对照设计;病例患者是2012-2019年间实验室确诊的沙门氏菌感染与碎牛肉相关的暴发，对照组是2018-2019年FoodNet人口调查的受访者，他们报告吃了碎牛肉，否认最近的胃肠道疾病。我们使用县级CDC/ATSDR社会脆弱性指数（SVI）来比较病例和对照。病例-患者状况根据县级社会脆弱性和个人层面的人口统计学特征进行回归。我们在FoodNet网站中确定了376名病例患者和1,321名对照。当根据个人水平调整时，作为病例患者与县级社会脆弱性（OR：1.21[95％CI：1.07-1.36]）和社会经济脆弱性（OR：1.24[1.05-1.47]）增加相关。病例-患者状态与家庭组成和残疾的其他SVI主题没有强烈关联，少数民族地位和语言，以及住房类型和运输。关于个人层面因素的数据，如收入，贫穷,失业,教育可以促进进一步的分析来理解这种关系。
