Investigation On Sleep Quality Of Radiation Workers In A Hospital Of Changchun City And Analysis Of Its Influencing Factors

Objective:With the continuous development of radiation technology,ionizing radiation has been used in many fields including the medical and health industry,providing great help for the diagnosis and treatment of diseases.This study intends to investigate the sleep quality of radiation workers in a grade-A hospital in Changchun City,to understand the sleep status of the population,and to propose countermeasures in a targeted manner,hoping to help hospital radiation workers improve their sleep quality.Based on the research data,suggestions are made to provide theoretical and practical basis for improving the quality of life of this population.Methods:In this study,all the radiation workers in the hospital in Changchun were selected as survey objects.A questionnaire survey was conducted on 212 people of the radiation staff of the hospital.210 questionnaires were actually collected,and the effective rate was 99.06%.The questionnaire was designed by the investigator and covered the socio-demographic characteristics,lifestyle,work-related characteristics,sleep quality,anxiety symptom,and depression symptom of the radiation staff.The original data was recorded by Epidata 3.0 software,and the statistical analysis was performed by SPSS24.0 software.The rate or composition ratio of each index was descriptively analyzed.The chi-square test and multi-factor logistic regression model were used to analyze various influencing factors.A P–value of less than 0.05 was considered statistically significant.Results:Among the 210 respondents included in the analysis,97 were male(46.2%)and113 were female(53.8%).The average age of the subjects was 33.84±7.98 years.The percentage of poor sleep quality of radiation workers in this survey was 22.4%.The total score of PSQI was 5.07±3.49 points.According to the distribution of factors of PSQI,44.8% of the subjects had daytime dysfunction.According to the percentage of poor sleep quality of the respondents,the prevalence of poor sleep quality was found to be different by genders(c 2=8.366,P=0.004),and the prevalence was lower in male than female.The prevalence was different between different educational levels(c 2=13.202,P<0.001),and the prevalence of poor sleep quality was lower in those with higher education level.There was no significant difference between age,marital status and monthly household income among radiation workers(P>0.05).There was no significant difference in the prevalence of poor sleep quality among subjects in different smoking and drinking status(P>0.05).The prevalence of poor sleep quality in subjects with irregular diet was 48.9%,which was higher than that of irregular diet(c2=24.580,P<0.001).The prevalence of poor sleep quality of subjects who regularly participated in physical exercise was 9.5%,which was lower than those who did not participate in physical exercise(c2=16.637,P<0.001).The prevalence of poor sleep quality of radiation workers in different types of work was different(c2=5.942,P=0.048),and the prevalence of poor sleep quality in subjects engaged in radiology,radiotherapy,nuclear medicine and interventional radiology was 16.0%,28.4% and 7.7% separately.Other characteristics including job position,radiation working years,average daily working hours,and average daily exposure to radiation equipment were not associated with poor sleep quality(P>0.05).The results of the anxiety and depression survey of radiation workers showed that there were 39(18.6%)radiation workers with anxiety symptoms and 53(25.2%)with depressive symptoms.The prevalence of poor sleep quality of radiation workers with anxiety symptoms was higher than those without anxiety symptoms(c 2=19.124,P<0.001),and the prevalence of poor sleep quality of radiation workers with depressive symptoms was higher than those without depression(c 2=25.076,P<0.001).Logistic multivariate regression analysis showed that regular diet,physical exercise,depression were the influencing factors of the sleep quality of the respondents(P <0.05).And regular diet,regular participation in physical exercise and no depressive symptoms are protective factors for good sleep quality.Conclusion:(1)The sleep quality of the radiation workers in the hospital is poor,and the prevalence of poor sleep quality is high;(2)the prevalence of anxiety and depression of radiation workers in the hospital was high;(3)diet,physical exercise and depression affect the sleep quality of radiation workers.
