Continuous Glucose Monitoring (CGM) in Healthy Japanese Female University Students Showed Early Morning Lower Sensor Glucose Values.

Abstract

In this study, Continuous Glucose Monitoring, a 24-h continuous sensor measurement of the glucose level, was performed on 35 female university students in their 20s. The results showed that 51.4% of the subjects had at least one episode of low sensor glucose level <54 mg/dL during the entire measurement period. This severe low glucose level condition was defined as lower sensor glucose values and it tended to occur more frequently during the early morning hours, especially from 3:00 am to 7:00 am. There were no significant differences in the BMI, the average number of steps, the total energy intake, the energy ratio of proteins, fats, or carbohydrates, or the alcohol intake between the lower sensor glucose values occurrence and the non-lower sensor glucose values occurrence groups. In regard to the early morning lower sensor glucose values observed in healthy female university students, we consider that further studies are required.
