华南某部队野外驻训期间急性腹泻病的流行病学研究

The epidemiological study of acute diarrhea during field training in an army of South China

目的 探讨部队野外驻训期间腹泻病的流行特征、病原特点和主要危险因素。方法 腹泻病发病监测、危险因素调查、病原菌分离。结果 驻训部队发病率为 4.36 % (10 6 / 2 433) ,高于同期常驻分队 0 .98% (2 / 2 0 4)的发病率。干部发病率低于战士的发病率。研究过程中出现两个与部队运动过程有关的发病高峰。患者粪便标本致泻菌检出率为 6 3.1% (6 5 / 10 3) ,检出最多的是产毒性大肠杆菌 ,其次为类志贺邻单胞菌。logistic回归分析共筛选出喝生水、外出就餐等 7个同腹泻病发生有关的因素。结论 该部队在野外驻训期间腹泻病明显增多 ,病原以产毒性大肠杆菌和类志贺邻单胞菌为主 ,且腹泻病的发生同多种危险因素有关。

Objective To probe into the epidemic feature, pathogenic spectrum and main risk factors of diarrhea during the field training in army. Methods Detection of morbidity,investigation of risk factors and detachment of pathogen were performed. Results The diarrheal incidence rate of army of field training was 4.36%(106/2 433), which was higher than that of hold garrison(0.98%, 2/204). The incidence rate of officers was lower than that of soldiers. Two incidence peaks concerned with the army motion course were found. The detection rate of lapactic bacteria from fecal of patients was 63.1%(65/103) and most of them were ETEC, followed by the plesiomonas shigelloides. Seven individual factors concerned with diarrhea disease were found with logistic analysis, including drinking unboiled water, going out to eating and so on. Conclusions Incidence of diarrhea in the army increased obviously during the field training and the chief pathogen are ETEC and plesiomonas shigelloides, at the same time, the occurrence of diarrhea is related with many individual factors.
