To identify risk factors for recurrent colic and chronic, intermittent colic in horses.
Case control study.
The population included 768 horses examined by veterinarians for emergencies other than colic (control group).
Horses with colic that had history of colic (n = 232) were compared with those without such history (n = 536), using logistic regression analysis to identify risk factors for history of previous colic and to determine odds ratios (OR) for these associations. Among the 232 horses in the history of colic group, 58 horses that had chronic, intermittent colic were compared with the no history of colic group and the control group to identify factors associated with chronic, intermittent colic, using multiple logistic regression analysis.
Among horses with colic, factors significantly associated with history of colic by multiple logistic regression analysis included history of abdominal surgery (OR = 3.1; P < 0.0001), age > 8 years (OR = 1.5; P < 0.0001), feeding of coastal grass hay (OR = 1.34; P 0.012), Arabian bread (OR = 1.28; P = 0.044), and recent change in stabling (OR = 0.76, P = 0.024). Among horses with colic, factors significantly associated with chronic, intermittent colic were history of previous abdominal surgery (OR = 2.2; P = 0.021), age > 8 years (OR = 2.0; P < 0.0001), being a gelding (OR = 1.7 with female as the reference population; P = 0.002), feeding of coastal grass hay (OR = 1.6; P = 0.045), and farm density < 0.5 horses/acre (OR = 1.6; P = 0.003). When the CIC group was compared with the control group, significant risk factors included history of abdominal surgery (OR = 270.7; P < 0.0001), age > 8 years (OR = 2.4; P < 0.0001), recent change in diet (OR = 2.1; P = 0.005), farm density < 0.5 horses/acre (OR = 2.0; P = 0.0001); being a gelding (OR = 1.8, with female as the reference population; P = 0.002), and Arabian breed (OR = 1.6; P = 0.050).
Certain findings of signalment and management factors may identify horses at increased risk of recurrent forms of colic.
确定马复发性绞痛和慢性间歇性绞痛的风险因素。
病例对照研究。
研究群体包括768匹因除绞痛以外的紧急情况接受兽医检查的马（对照组）。
将有绞痛病史的马（n = 232）与无此类病史的马（n = 536）进行比较，采用逻辑回归分析确定既往绞痛病史的风险因素并确定这些关联的优势比（OR）。在有绞痛病史组的232匹马中，将58匹患有慢性间歇性绞痛的马与无绞痛病史组和对照组进行比较，采用多元逻辑回归分析确定与慢性间歇性绞痛相关的因素。
在患有绞痛的马中，通过多元逻辑回归分析与绞痛病史显著相关的因素包括腹部手术史（OR = 3.1；P < 0.0001）、年龄>8岁（OR = 1.5；P < 0.0001）、饲喂海滨草干草（OR = 1.34；P = 0.012）、阿拉伯马品种（OR = 1.28；P = 0.044）以及近期厩舍环境变化（OR = 0.76，P = 0.024）。在患有绞痛的马中，与慢性间歇性绞痛显著相关的因素为既往腹部手术史（OR = 2.2；P = 0.021）、年龄>8岁（OR = 2.0；P < 0.0001）、去势公马（以母马作为参照群体，OR = 1.7；P = 0.002）、饲喂海滨草干草（OR = 1.6；P = 0.045）以及农场密度<0.5匹马/英亩（OR = 1.6；P = 0.003）。当将慢性间歇性绞痛组与对照组进行比较时，显著的风险因素包括腹部手术史（OR = 270.7；P < 0.0001）、年龄>8岁（OR = 2.4；P < 0.0001）、近期饮食变化（OR = 2.1；P = 0.005）、农场密度<0.5匹马/英亩（OR = 2.0；P = 0.0001）、去势公马（以母马作为参照群体，OR = 1.8；P = 0.002）以及阿拉伯马品种（OR = 1.6；P = 0.050）。
某些体征和管理因素的发现可能有助于识别复发性绞痛风险增加的马。
