Investigation And Logistic Regression Analysis On Influencing Factors Of Sleep Quality Of Clinic Nurses In Third-Grade Hospitials

Objective:The purposes of this study were to explore the influencing factors of the sleep quality of clinic nurses in third-grade hospitials and to offer concrete measures to improve clinic nurses'sleep quality and promote health on the basis of the resules from this study.Methods:The investigation was conducted among the clinic nurses from third-grade hospitals in Weifang,with the two-stage sampling method.In brief,three hospitals were selected at random in terms of proportion of general hospital and special hospital,then a total of 600 clinic nurses were sampled according to the proportion of nurses in three hospitals.The research tools include Pittsburgh Sleep Quality Index(PSQI).General Health Questionnaire(GHQ-12) and a self-made questionnaire about influencing factors of sleep quality of clinic nurses in third-grade hospitals.PSQI consists of 19 items which are composed of 7 aspects. including subjective sleep quality,sleep latency,sleep duration,sleep efficiency. sleep disturbance,use of sleep medication and day-time dysfunction.Each aspect is scored from 0 to 3,if the cumulated score is under eight,the sleep qulity is considered to be high.otherwise it was considered to be low.GHQ-12 is composed of 3 parts,including somatic symptoms,anxiety,or worry,and depression.It is scored in a bimodal fashion(0-0-1-1).with higher scores representing more symptoms of psychologic distress that the object experiences.The data collected with the same questionnaire for the clinic nurses,was input to computer using Excel 2003.After one-way logistic regression analysis for the qualified variables,mutipule logistic regression was used for selecting the influencing factors to establish the best regression model.All the analyses were anslysed with SAS 8.2 and SPSS 13.0.Results:A total of 600 clinic nurses were investigated,in which 547 was used for analysis and 53 were not qualified by checking the questionnaires.Among 547 clinic nurses,157(28.70%) had a low sleep qulity.The results showed that there were significant differences in age,marital status and position with regard to sleep quality;on the contrary,there were no significant differences in quality of sleep related to education background,working years and department.The correlation among sleep quality and whole of mental health,somatic symptoms,depression, anxiety was statistically significant.The simple analysis process about the influencing factors of sleep quality is that we tested the linear correlation between independent variables and logit P,and found that there's a logarithm form between x₃ and logit P,and a third-order relationship form respectively between x₁₈ or x₂₅ and logit P.therefore,x₃ was analyzed with logarithm form,and x₁₈ and x₂₅ were analyzed with cube form.21 factors was screened out from 33 dubious influencing factors by one-way logistic regression analysis with the significant criteria of 0.15,and no co-linearity among the 21 factors was found after the co-linearity diagnosing.After multivariate analysis,8 factors were screened out which were worry of sleep,the emotion when they were rescuing patients,pressure of study,late sleeping,irregular work or rest,family relationship,intensity of work and self-evaluated health condition.Conclusion:According to the resules of the study,we considered that the sleep quality of clinic nurses could be improved from two aspects,nurse manager and nurses themselves.As far as nurse manager is concerned,they should optimize working system,allocate the clinical nursing human resources reasonably, strengthen education of nurses sleep hygiene and mental health education,and enhance professional training and examing.As for nurses themselves,they'd better correctly realize the importance of sleep,cultivate healthy lifestyles,build harmonious family relationship,and enhance their psychological adjustment ability.
