title: [An epidemiological study on acute diarrhea during a filed exercise in PLA unit in an area in southern China].
abstract: 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 total.
  
  
  CONCLUSIONS
  These results provided a basis for prevention of acute diarrheal disease during filed exercise of military action.
