Abstract: Objective To investigate the cervical vertebrate sub-health status of medical staff and its influencing factors, and to provide a reference for preventing and improving the cervical vertebrate sub-health of medical staff. Methods The simple sampling method was used to conduct a questionnaire survey on the medical staff of different positions in 2 tertiary hospitals and 2 secondary hospitals from April to June 2022. The basic information, lifestyle, work factors, and cervical vertebrate discomfort were collected. The cervical vertebrate sub-health status of medical staff and its influencing factors were analyzed by univariate and multivariate Logistic regression methods. Results A total of 1 196 medical staff were investigated, and 1 084 effectively responded, with an effective response rate of 90.64%. There were statistically significant differences in the incidence of cervical vertebrate sub-health among medical staff with different ages, body mass index （BMI）, daily screen time, physical exercise, sleep time, job position, working years, average daily working time, night shift frequency, forced posture, and heavy physical work （P<0.05 or P<0.01）. Multivariate Logistic regression analysis showed that age （OR=1.241）, BMI （OR=1.581）, daily screen time （OR=5.825）, physical exercise （OR=0.269）, sleep time （OR=0.620）, job position （physician OR=1.389, nurse OR=1.634）, average daily working time （OR=1.822）, night shift frequency （OR=1.982）, forced posture （OR=2.547）, and heavy physical work （OR=1.673） were influencing factors of cervical vertebrate sub-health of medical staff. Conclusions The incidence of cervical vertebrate sub-health among medical staff is relatively high, which is affected by their basic characteristics, lifestyle, work factors, etc. So it is necessary to pay attention to the high-risk population to adjust their life and work status to prevent cervical spondylosis.
