Objective To provide ideas on nutritional support for medical workers， the use and awareness of dietary supplements among medical workers for the normalization of COVID-19 epidemic prevention was explored.Methods From January to April 2021， questionnaires were distributed to a convenient sampling survey of medical workers of the Eastern Health Care Group that had participated in the fight against the new coronavirus pneumonia epidemic. Data from 188 electronic questionnaires were collected and the SPSS 22.0 software was used for statistical analysis.Results The overall dietary supplement consumption rate of medical workers was 22.34% （42/188）. Workers that were non-drinkers and had a high educational level were significantly more likely to consume dietary supplements than those who were drinkers and had a low educational level （P<0.05）. However， the difference in fatigue and self-assessed health statuses was not significant between individuals who consumed dietary supplements and those that did not （P>0.05）. In terms of awareness attitudes， individuals consuming dietary supplements agreed more with the three viewpoints of “dietary supplements are safe”， “dietary supplements have certain health effects” and “interaction with drugs” （P<0.05）. The three dietary supplements mainly consumed by medical workers were compound vitamin and mineral preparations （59.52%）， single vitamin preparations （57.14%）， and protein powders （40.48%）. The results of the logistic regression analysis showed that the factors influencing dietary supplement consumption by medical workers were mainly educational level （OR = 7.314） and belief that dietary supplements were safe （OR = 0.098）.Conclusion The consumption rate of dietary supplements among medical workers was low. The nutritional support of medical workers should receive attention to ensure the health status of medical workers under the normalization of epidemic prevention.
