The KAP scores were analyzed,and the influencing factors were analysed by ANOVA and multiplelinear regression.Results The scores of KAP related to RTIs were(15. 41 ± 4. 50),(41. 16 ± 5. 85) and(55. 46 ± 6. 83), respectively. Multiple linear regression analysis showed that region, annual family income and separate bathroom were factors associated with knowledge of RTIs(P< 0. 05). Age, job characteristics of women and their spouses and number of children were factors associated with health belief(P< 0. 05). Region, annual family income and women's job characteristics were factors associated with health behavior(P< 0. 05).Conclusion Knowledge and health behavior of RTIs among rural married women of child-bearing age is acceptable, but their health belief needs to be improved.
