Objective: To investigate the related factors of allergic cough in children (1-3 years old), and to to prevent and treat the allergic cough better. Methods: 129 children with anaphylactic cough and 139 children with non-anaphylactic cough in the same period were selected as the research objects. The data in the questionnaire were collected and entered into the computer using a unified questionnaire survey method. Results: The results showed that there were significantly positive correlation factors with allergic cough in children in early childhood: increased sensitivity of pressing Tiantu (OR: 6.347), history of repeated breathing to infection (OR: 7.895), history of allergic rhinitis (OR: 5.295), "|" (OR: 4.052) in the veins of mountain roots, irritating odor induction (OR: 5.069), and mycoplasma pneumoniae infection (OR: 3.284) (P<0.01). However, tongue pricking, sweating or night sweating, large temperature difference in the climate, rubbing nose and eyes, and being active will not affect the disease. Conclusion: The risk factors of anaphylactic cough in children in early childhood involve environment, respiratory tract infection and the specific positive signs of traditional Chinese medicine, which is worthy of further exploration.
