目的 :探讨部队野外驻训期间急性腹泻病的个体和群体危险因素 ,为制定防治措施提供参考依据。方法 :对南方某高炮部队野外驻训期间的急性腹泻病资料进行收集、整理、统计、分析。结果 :多因素Logistic回归分析发现个体发生腹泻病的危险因素为发病前 7d喝生水、外出就餐、接触腹泻病人、卫生知识缺乏、精神抑郁、不常剪指甲和睡眠时间不足 ;发生严重病例的危险因素为发病前 7d喝生水、外出就餐和饭前不洗手。回归和判别分析结果显示 ,驻训部队的发病率与其苍蝇密度和人均日供开水量有关 ,由 6个因素组成的发病率判别方程的判别正确率达 91.9%。结论 :本结果为部队在紧急状态下野外驻训期间腹泻病的预防提供了参考依据 ,具有一定的实用价值 Objective: To explore the individual and group risk factors of acute diarrhea during field training in the field and provide a reference for the formulation of prevention and treatment measures. Methods: The data of acute diarrheal disease during field training of an anti-aircraft artillery unit in southern China were collected, collated, analyzed and statistically analyzed. Results: The multivariate Logistic regression analysis found that the risk factors of diarrhea were 7 days before the onset of drinking water, eating out, patients with diarrhea, lack of health knowledge, depression, uncommon nails and lack of sleep time; severe cases Risk factors for the first 7d before onset of raw water, eating out and washing hands before meals. The results of regression and discriminant analysis showed that the incidence rate of the troop movements was related to the density of flies and the daily water supply per person. The discriminant accuracy of the discriminant equation composed of six factors was 91.9%. Conclusion: The results provide a reference for the prevention of diarrheal diseases during field training in the state of emergency, and have certain practical value
