Conditional logistic regression model was used in the univariate and multivariate analysis. [Results] The results of univariate analysis showed that domestic hygiene, intake of suspicious foods, washing hands before dining and washing hands after defecation were related to bacillary dysentery, their OR values were 0.48, 94.00, 0. 38 and 0.40 respectively. The results of multivariate analysis showed that intake of suspicious foods and washing hands before dining were related with bacillary dysentery. [ Conclusion ] Intake of suspicious foods is the chief risk factor while washing hands before dining is the chief protective factor for bacillary dysentery.
