Bovine cysticercosis is a zoonotic parasitic disease due to Cysticercus bovis. This study aimed to identify factors that could have an impact on the prevalence of cysticercosis and to use them to build standardized indicators of prevalence. Multivariate logistic regression analyses were performed on data from 4,564,065 cattle (91.3% of the cattle population slaughtered in France in 2010) among which 6491 cattle (0.14%) were found to harbor at least one lesion of cysticercosis (including 611 cattle harboring viable cysts, 0.01%). Two multivariate logistic models were fit to the data using as outcome variables either the presence or absence of viable cysts and the presence or absence of cysts whatever their level of development. Age and sex were identified as the main factors influencing bovine cysticercosis prevalence and were used for the construction of standardized prevalence and standardized cysticercosis rate. To illustrate the use of such indicators, they were calculated for the first and second semester of 2010 and for two different areas in France. The differences between raw prevalence and standardized prevalence highlight the use of standardized indicators for comparisons of prevalence between different areas and time periods as the structure of the slaughtered populations differ considerably from one to another.
牛囊尾蚴病是一种由牛带绦虫幼虫引起的人畜共患寄生虫病。本研究旨在确定可能影响囊尾蚴病流行率的因素，并利用这些因素构建流行率的标准化指标。对 2010 年法国屠宰的 4564055 头牛（占牛群的 91.3%）中的数据进行了多变量逻辑回归分析，其中 6491 头牛（0.14%）至少存在一个囊尾蚴病病灶（包括 611 头含有活囊尾蚴的牛，占 0.01%）。使用两种多变量逻辑模型，将存在或不存在活囊尾蚴以及存在或不存在无论其发育程度如何的囊尾蚴作为因变量，拟合数据。年龄和性别被确定为影响牛囊尾蚴病流行率的主要因素，并用于构建标准化流行率和标准化囊尾蚴率。为了说明这些指标的使用，它们是为 2010 年第一和第二学期以及法国的两个不同地区计算的。原始流行率和标准化流行率之间的差异突出了标准化指标在不同地区和时间段之间比较流行率的用途，因为屠宰人群的结构彼此之间有很大的不同。
