A retrospective longitudinal study of metritis was conducted in Denmark on data collected during 1993-1994. Data on herd size, breed, parity, and treatment of disease were obtained from the Danish Cattle Database. Management and production-facility data were collected using a questionnaire, conducted as a telephone interview in 1994. The study included 2144 herds from three regions in Denmark (102,060 cows). Herd-level variables included were: herd size, housing, flooring, grazing, calving measures, and calving supervision. Cow-level variables were: parity, breed, calving season and whether the cow had been treated by a veterinarian for dystocia or the diseases: retained placenta, reproductive disease, ketosis, milk fever, or dry cow mastitis. Marginal multivariable logistic-regression analyses were performed. The cow with highest odds of metritis was a first or greater than or equal to third parity cow, of large breed, that calved during November-April, in a zero-grazing herd. The cow had been treated for dystocia, retained placenta, and at least one other reproductive disease, but not for ketosis.
1993年至1994年期间，丹麦利用收集的数据对子宫内膜炎进行了一项回顾性纵向研究。畜群规模、品种、胎次和疾病治疗的数据来自丹麦牛数据库。管理和生产设施数据通过问卷调查收集，于1994年进行电话访谈。该研究包括丹麦三个地区的2144个畜群（102060头奶牛）。纳入的畜群水平变量包括：畜群规模、住房、地板、放牧、产犊措施和产犊监督。奶牛水平变量包括：胎次、品种、产犊季节以及奶牛是否因难产或以下疾病接受过兽医治疗：胎盘滞留、生殖疾病、酮病、产乳热或干奶牛乳腺炎。进行了边际多变量逻辑回归分析。患子宫内膜炎几率最高的奶牛是头胎或胎次大于或等于第三胎的奶牛，大型品种，11月至4月产犊，且处于零放牧畜群中。该奶牛因难产、胎盘滞留和至少一种其他生殖疾病接受过治疗，但未因酮病接受过治疗。
