Abstract: Objective To identify the main risk factors of human cystic echinococcosis in Shiqu County, Sichuan Province, so as to provide the reference for the formulation of echinococcosis control strategies in Shiqu County. Methods During the period from November 2015 through June 2017, the patients with cystic echinococcosis (case group) and healthy controls (control group) were randomly sampled from Shiqu County as the study subjects. A questionnaire survey was conducted to capture the study subjects’ age, gender, ethnicity, occupation, religion, lifestyle, education level, number of household dogs, bovine and sheep, and density of dog feces in the courtyard. The major risk factors of human cystic echinococcosis were identified using a logistic regression model. Results Univariate logistic regression analysis showed 7 risk factors with statistical significance between the case and control groups, and age, lifestyle, number of household bovine, number of household sheep, number of household dogs, and the density of dog feces in the courtyard were included in the multivariate logistic regression model (OR = 1.026, 4.792, 1.067, 1.022, 1.709 and 1.095, respectively). Conclusion High age, pastoral nomadic lifestyle, high number of household bovine, high number of household sheep, high number of household dogs and high density of dog feces in the courtyard are strongly associated with the riks of human cystic echinococcosis in Shiqu County.

摘要: 目的 探索四川省石渠县人群细粒型棘球蚴病的主要影响因素,为制定相应的防治策略提供参考依据。方法  2015年11月-2017年6月,随机抽取四川省石渠县细粒棘球蚴病患者(病例组)和健康者(对照组)作为调查对象,通过问卷调查患者年龄、性别、民族、职业、宗教信仰、居住方式、文化程度等人口学特征,以及家庭饲养犬、牛、羊数以及庭院内犬粪便密度等信息,建立logistic回归模型分析居民患细粒棘球蚴病的主要影响因素。结果 单因素logistic回归分析结果显示,细粒棘球蚴病患者危险因素在病例组和对照组有统计学意义的有7项,年龄、居住方式、养牛数、养羊数、养犬数、庭院内犬粪便密度等6个因素进入了多因素logistic回归模型,OR值分别为1.026、4.792、1.067、1.022、1.709、1.095。结论 高年龄组、游牧生活方式、养牛数多、养羊数多、养犬数多、庭院内犬粪便密度大等因素与四川省石渠县居民患细粒棘球蚴病高度相关。
