Abstract Objective To analyse the nasopharyngeal bacterial carrying and risk factors of respiratory tract infection in preschool children. Methods From August 2016 to June 2017, 115 cases of preschool children with respiratory tract infection in Huangshi Aikang Hospital (“our hospital” for short) were selected, divided it into observation group. In the same period, another 115 preschool children who went to our hospital for physical examination were selected as the control group. All the children received 1 nasopharyngeal secretory specimens for bacterial isolation and culture. The bacterial infection types of nasopharyngeal bacteria were analyzed, and the risk factors were analyzed according to the age, sex and activities of daily living. Results After the testing, preschool children with respiratory tract infections of nasopharyngeal bacteria mainly Haemophilus Influenzae, Staphylococcus Aureus, Klebsiella Pneumoniae. The premature delivery, antibacterial drugs were used more frequently, the family members had respiratory diseases, partial eclipse or picky eaters, family smoking, poor family hygiene were related to respiratory tract infections in preschool children (P < 0.05). Logistic regression analysis showed that the premature delivery, antibacterial drugs were used more frequently, the family members had respiratory diseases, partial eclipse or picky eaters, family smoking were all high risk factors of respiratory tract infection in preschool children (P < 0.05). Conclusion The main types of nasopharyngeal bacteria carrying by respiratory tract infection in preschool children are haemophilus influenzae, staphylococcus aureus, klebsiella pneumoniae, and there are many risk factors for the disease, clinic should select appropriate treatment according to bacterial resistance methods, at the same time for the risk factors for the disease to take targeted preventive measures to reduce the risk of respiratory infection in preschool children.
