Abstract: Objective To explore the influencing factors of foreign body aspiration (FBA) and parents′ knownledge regarding of FBA,and to provide theoretical basis for prevention and control of diseases. Methods A retrospective review was done in 202 patients who had FBA from October 2017 to January 2019 in the Second Affiliated Hospital of Xi′an Jiaotong University. During the same period,100 patients with acute laryngitis were recruited continuously as the control group. The questionnaire of parental awareness of children′s FBA was used to investigate the children’s parents about the knownledge related to FBA. Results Among the 202 children with FBA,86.2% were under 3 years old,with 1.85∶1 in male and female ratios,2.74∶1 in the ratio of urban and rural areas,and 68.4% of parents were under high school education. Wooden tracheobronchial foreign bodies were mainly in 191 cases (94.6%),including 158 cases (78.2%) of nuts and beans. The main causes was crying while having a meal (68.3%). Only 15.8% cases got effective treatment during the initial 24 hours after FBA. There were statistically significant differences in parents recognition of the types of foreign bodies,children′s eating patterns and the general cognition of FBA between FBA group and control group (χ²=4.47,5.32,11.17 respectively,P<0.05),with no significant difference in the cognition of FBA symptoms (χ²=0.61,P> 0.05). Conclusion Children′s FBA have obvious epidemic characteristics in age,gender,urban and rural areas,and caregivers′ educational level. Parents′ low cognition may be the main reason for the high incidence of FBA.
