Abstract: Objective To understand the current cognitive status of health science popularization among medical staff in a certain district of Tianjin and the influencing factors of their participation in science popularization work,analyze their training needs,and propose suggestions to enhance their science popularization capabilities. Methods By using random sampling method,340 medical personnel from a district in Tianjin from July to August 2024 were selected as the survey subjects. A self-designed health science popularization cognition survey questionnaire was used,and data collection and analysis were completed through the Wenjuanxing platform,and the data were analyzed. Results In terms of the implementation status of science popularization among 340 medical personnel,228（67.06%） medical personnel had participated in science popularization activities in the past five years. The top three science popularization targets were 186 general public（54.71%）,176 outpatient or inpatient patients（51.76%）,and 136 patient family members（40%）. Totally 205 people（60.29%） consulted through free clinics,122 people（35.88%） published science popularization articles through new media,90 people（26.47%） produced short videos,and 70 people（20.59%） published science popularization articles through traditional media. In terms of willingness and influencing factors for science popularization：90.29% of the respondents expressed willingness to participate in science popularization work,mainly motivated by recognizing the value of science popularization（85.29%）,promoting doctor-patient communication（72.94%）,and valuing science popularization work in their units（44.41%）. In terms of demand for science popularization training：265 people（77.94%） with "suitable content",211 people（62.06%） were engaged in "article writing and editing",189 people（55.59%） were involved in video production,74 people（21.76%） participated in legal policy lectures.

The problems in science popularization included uneven attention from leaders of various units,uneven implementation of science popularization work（55.88%）,and lack of review of science popularization content（55.88%）. In terms of incentive measures,66.76% of medical staff suggested improving the system,and 43.82% of medical staff believed that science popularization work should be valued in performance evaluation and promotion. Conclusion Totally 340 medical staff generally attach importance to health science popularization work and have a high willingness to participate,but they need systematic training support.
