南方某部队野外驻训期间急性腹泻病流行病学研究

An epidemiological study on acute diarrhea during a filed exercise in PLA unit in an area in southern China

目的 对野外驻训期间我军腹泻病的流行特征及危险因素进行初步研究。方法 对某部队野外驻训期间腹泻病发病进行流行病学调查 ,统计方法采用多元线性逐步回归和判别分析。结果 参训部队腹泻发病率较同期该地常年驻军显著增高 (7.32 %vs 0 .98% ,P <0 .0 5 ) ;干部发病率低于战士 (0 .99%vs 8.2 0 % ,P <0 .0 5 ) ;腹泻的发生贯穿整个非常时期 ,但高峰期常见于初期 ,此后逐渐趋于平稳 ,并可时有大小不等的散在暴发 ;发病率的单位分布存在明显差异。经回归和判别分析 ,结果显示发病率与参训单位的苍蝇密度和人均日供开水量有关 ,判别模型总的判别正确率达91.9%。

Objective To explore the epidemiological characteristics and risk factors of acute diarrheal disease during a filed exercise. Methods Epidemiological study of a certain artillery acute diarrheal disease during a filed exercise and multiple linear stepwise regression analysis, multiple stepwise discriminate analysis were used. Results Result showed that the incidence rate of training troops was significantly higher than that of the local troops at the corresponding period ( 7.32 % vs 0.98 % P < 0.05 ). The incidence rate among officers was significantly lower than that of the soldiers (0.99% vs 8.20 % P < 0.05 ). The incidence rate was significantly higher at the beginning of assemble for training but smooth and steady afterwards with several outbreaks. There was highly significant difference in the incidence rate of 39 companies. Regression and discrimination analysis suggested that the incidence rate was correlated with the density of flies and average boiled water volume provided everyday. The correct classifying rate of the discrimination was 91.9% in totall. Conclusion These results provided a basis for prevention of acute diarrheal disease during filed exercise of military action.
