The Preliminary Study On Sleep Quality And Its Influencing Factors Of Radiation Workers In A Region

ObjectiveOur purpose is to investigate sleep quality and its influencing factors of radiation workers in some city,in order to provide support for building a scientific sleep evaluation system for radiation workers,and the safe operation of the radioisotope and ray devices.Methods1. Assessment tool: The Pittsburgh sleep quality index(PSQI) was used to assess subjective sleep quality. The Self-reporting Inventory(SCL-90)、Eysenck Personality Questionnai(EPQ)、self-evaluation anxiety scale(SAS)and self-rating depression scale(SDS)which were domestic widely used to test on the radiation worker.2. Sample collection: The samples came from siven hundred and fifty radiation workers in some city, sample extraction using cluster random sampling method.3. Standard test: The test was arranged,supervised and conducted by professional testers, and subjects were asked to complete test on the spot according to unified instruction. The environment was required to be quiet and comfortable while testing,avoiding all the other potential interferences.4. Statistical analysis: All analyses were performed using the SPSS computer software version 19.0 for Windows(IBM SPSS Statistics). Descriptive analysis was used to analyze basic characteristics of the subjects with mean values ± standard deviation(SD). Scores for the PSQI,SCL-90、EPQ、SAS and SDS were compared using Student’s t test, one-way ANOVA analysis., correlation analysis and binary logical regression analysis.Results of comparisons with a p value of < 0.05 were considered to representstatistically significant differences.Results1 The preliminary study on sleep quality of radiation workers in a region1.1. The score for PSQI and its factors of radiation workers in a regionSleep assessment revealed that the mean PSQI was 5.14±2.31 and 17.6% of subjects had a score of 7 above, indicating a poor sleep quality. Subjects had a relatively higher score(score of 2 or above) in daytime dysfunction(30.7%), subjective sleep quality(22.1%) and sleep latency(19.5%).1.2 Influence analysis of demographic variable of sleep quality on the radiation workersThe radiation workers of different sex showed significant differences on PSQI,subjective sleep quality, sleep duration,and daytime dysfunction. The radiation workers of different work’s significant difference came from PSQI, sleep duration and use of sleep medications. The radiation workers’ subjective sleep quality, use of sleep medications related with age, and the use of sleep medications related with length of service. The radiation workers of different education’s significant difference came from daytime dysfunction. The radiation workers of different marital status showed significant differences on PSQI, subjective sleep quality, sleep latency, sleep duration, daytime dysfunction. The radiation workers of different income’s significant difference came from sleep disturbances and use of sleep medications.2 The preliminary study on influencing factors of sleep quality of radiation workers in a region2.1 The correlation between sleep quality and every single factorThe radiation workers’ general symptomatic index was 1.48±0.42,and the mean PSQI was positively correlated with general symptomatic index and every factor of SCL-90.The mean PSQI was positively correlated with scale P,N,and negatively correlated with scale E.The radiation workers’ SAS average was 41.62±9.91,SDS average was 47.77±9.32, and the mean PSQI was positively correlated with SAS average and SDS average.2.2 The influencing factors of sleep quality of radiation workersMultiple factors logistic regression showed that SAS average,SDS average, general symptomatic index, scale E and the training,were related with sleep quality(χ2=445.827,P<0.01).ConclusionsPSQI,SCL-90, EPQ,SAS and SDS which were effective tool for evaluation on the radiation workers adopted by the subject has carried on the preliminary study of the radiation workers.1.The sleep quality of the radiation workers is normal and can be competent for the job, but there are some differences between different groups of the radiation workers.2.SAS average,SDS average, general symptomatic index, scale E and the training were related with sleep quality.3.We can organize the training and give appropriate intervention measures to improve their sleep quality.
