Colic is an important health problem in managed horse populations. Currently, there is limited information about colic prevalence and risk factors for colic in working horse populations.
To determine the prevalence of, and risk factors for, colic in a working horse population in Egypt and to describe management practices in this working horse population.
Cross-sectional survey.
Owners of 350 working horses were interviewed. Data about their horses, management and colic episodes in the preceding 12 months were collected. Dental examination was conducted on 342 horses and blood samples (n = 100) were collected for immunodiagnosis of tapeworm (Anoplocephala perfoliata) infection. Multivariable logistic regression analysis was used to identify risk factors for a history of colic in the preceding 12 months.
The 12-month prevalence of colic was 54.6%. Severe and moderate tapeworm infection intensity was identified in 3% and 26% of horses tested, respectively. Horses that had severe dental disease (odds ratio [OR] 6.8, 95% confidence interval [CI] 1.9-24.3, P<0.001), that displayed stereotypic behaviour (OR 2.0, 95% CI 1.15-3.5, P = 0.013), were fed ground corn during the 'dry season' (OR 1.65, 95% CI 1.03-2.6, P = 0.035) or that had received an anthelmintic in the previous 6 months (OR 2.1, 95% CI 1.3-3.3, P = 0.003) were more likely to have a history of colic in the preceding 12 months. Horses fed on rice bran during the 'green season' (OR 0.47, 95% CI 0.26-0.9, P = 0.015) and that displayed geophagia/coprophagia (OR 0.19, 95% CI 0.05-0.73, P = 0.001) were less likely to have a history of colic.
Colic is common in this working horse population and this study has identified factors associated with altered likelihood of colic. The study provides important information that may be used to inform future prospective studies investigating colic in working horse populations and to assist development of preventive healthcare strategies.

腹痛是圈养马群中的一个重要健康问题。目前，关于役用马群中腹痛的患病率及风险因素的信息有限。
确定埃及役用马群中腹痛的患病率及风险因素，并描述该役用马群的管理方式。
横断面调查。
对350匹役用马的主人进行访谈。收集有关其马匹、管理方式以及过去12个月内腹痛发作情况的数据。对342匹马进行口腔检查，并采集100份血样用于绦虫（叶状裸头绦虫）感染的免疫诊断。采用多变量逻辑回归分析来确定过去12个月内有腹痛病史的风险因素。
腹痛的12个月患病率为54.6%。在接受检测的马匹中，分别有3%和26%被确定为重度和中度绦虫感染。患有严重口腔疾病的马（比值比[OR] 6.8，95%置信区间[CI] 1.9 - 24.3，P<0.001）、表现出刻板行为的马（OR 2.0，95% CI 1.15 - 3.5，P = 0.013）、在“旱季”被喂食碎玉米的马（OR 1.65，95% CI 1.03 - 2.6，P = 0.035）或在过去6个月内接受过驱虫药治疗的马（OR 2.1，95% CI 1.3 - 3.3，P = 0.003）在过去12个月内更有可能有腹痛病史。在“绿季”以米糠为食的马（OR 0.47，95% CI 0.26 - 0.9，P = 0.015）以及表现出土食癖/食粪癖的马（OR 0.19，95% CI 0.05 - 0.73，P = 0.001）有腹痛病史的可能性较小。
腹痛在该役用马群中很常见，本研究已确定了与腹痛发生可能性改变相关的因素。该研究提供了重要信息，可用于为未来调查役用马群腹痛情况的前瞻性研究提供参考，并有助于制定预防性医疗保健策略。中文摘要见补充信息。
