Objective: To investigate the status of knowledge, attitude and practice about first aid and influencing factors in key population, those who have frequent contacts with people and might be "first aid" promoter in general population of Beijing, and provide evidences for the promotion of first aid. Methods: This study was a cross-sectional survey based on the "Emergency Rescue Capacity Training Project". Using cluster sampling, we recruited 9 591 participants after the training in Beijing for survey with a self-designed questionnaire from October 2021 to March 2022. Results: In 9 591 participants, 98.58% knew the emergency call number, while only 32.00% knew how to identify sunstroke. The awareness rate of the definition of first aid and legal disclaimer were lower (63.61%, 75.91%). People's willingness to give first aid to others, including relative, acquaintance, stranger and vagrant, were different (χ²=822.82, P<0.001). People were more likely to give first aid to relative, acquaintance and stranger compared with vagrant (P<0.05). With the increase of psychological distance, the willingness to give first aid decreased (Z=-26.57, P<0.001). According to the results of Logistic regression analysis, older age, higher annual family income and higher awareness of first aid related knowledge were contributing factors for giving first aid. In 1 529 people who met emergency, only 66 people (4.32%)did not give any first aid. Conclusions: The key population in Beijing has high awareness of first aid related knowledge and positive attitude of first aid after training. A high proportion of people performed first aid to others. Age, annual family income and awareness of first aid related knowledge were contributing factors for giving first aid.
