Correlation between sleep lasting time and blood glucose control in patients with gestational diabetes mellitus / 重庆医学

ABSTRACT

Objective To investigate the relationship between sleep status and blood glucose control in the patients withgestational diabetes mellitus (GDM).Methods The pregnant women and parturients clinically newly diagnosed as GDM without starting insulin or glibenclamide treatment were included in this study.The subjects were instructed to correctly use the glucometer and comply with the GDM dietary principles.All subjects recorded the sleep log for consecutive 7 d,including the time going to bed and wake time.The linear mixed model was used to analyze the relationship between the sleep lasting time with morning fasting blood glucose and postprandial 1 h blood glucose level.Results The complete sleep logs of consecutive 7 d and blood glucose detection values were finally collected from 65 subjects.The sleep duration shortening had significantly negative correlation with fasting and postprandial 1 h bloodglucose levels.After adjusting age,gestational age and BMI,every increase 1 h of sleep lasting time,the fasting blood glucose level was significantly decreased,there was significant correlation between them[-2.13 mg/dL,95 ％CI(3.98,-0.20)],meanwhile postprandial glucose level was also decreased,they were significant correlation as well[lunch-4,62 mg/dL,95％CI (-8.75,-0.50) vs.dinner-6.07 mg/dL,95％CI(-9.40,-2.73)].Conclusion The sleep lasting time shortening is closely correlated with poor glucose control in the patients with GDM.Informing GDM patients the importance of sufficient sleep,meanwhile early finding and treating the patients with existing sleep disorder can optimize their blood glucose control level.
