Investigation of sleep quality and its influencing factors in maintenance hemodialysis patients / 中华肾脏病杂志

ABSTRACT

Objective To investigate the sleep quality of maintenance hemodialysis (MHD) patients and analyze its associated factors. Methods The convenience sample method was used to choose 424 MHD patients from 7 hospitals.A set of questionnaires were used in this investigation,including demographic data form,Pittsburgh sleep quality index (PSQI),restless legs syndrome (RLS),social support rate scale (SSRS),subjective global assessment (SGA),family APGAR index (APGAR) and family burden scale of disease (FBS). Results PSQI score of 395 MHD patients (93.2％) was ≥5.APGAR and social support total points were negatively correlated with sleep quality (r=-0.133,P=0.006; r=-0.105,P=0.031).Family burden total point was positively correlated with sleep quality (r=0.215,P=0.000).Nutrition (F=46.123,P=0.000),restless legs syndrome (F=9.392,P=0.000) and sleep apnea syndrome (F=5.645,P=0.001) were closely associated with sleep index scores. Conclusions Incidence of poor sleep quality in MHD patients of our study is quite high.Sleep quality of MHD patients is correlated with lots of factors,such as family concern,social support.
