School vs. Holidays: Do Blood Sugar Levels Really Change? New Study Has Answers

Researchers wanted to know whether kids and teens using open-source artificial pancreas systems—a type of automated insulin delivery technology—would have different blood sugar control during school days compared to holidays. It's a practical question many families ask: Does the routine of school help keep blood sugars steadier, or do the changes that come with holidays matter?

The study included 55 young people aged 6 to 19 years who had been using an open-source Android artificial pancreas system for at least three months. The researchers collected continuous glucose monitoring (CGM) data and sorted it into two groups: school days and holiday periods.

The results were reassuring: glycaemic control remained consistent whether young people were in school or on holiday. The study measured multiple aspects of blood sugar management—including time in range, time in tight range, average glucose levels, and glucose variability—and found no meaningful differences between the two schedules.

This stability held true across the whole day, during daytime hours, and overnight. The artificial pancreas systems appeared to adjust effectively to the lifestyle changes that come with school transitions, suggesting these systems are robust enough to handle routine shifts.

While school and holiday schedules produced similar results overall, one factor did stand out: sleep. Young people who slept longer at night were more likely to achieve better blood sugar control during school days. Specifically, longer nighttime sleep was associated with higher time-in-tight-range and time-in-range readings.

This finding highlights the importance of sleep quality and duration for overall diabetes management—a reminder that consistent rest matters alongside technology and treatment.

For families using open-source artificial pancreas systems, this study offers practical reassurance: the technology appears to work reliably whether your child is following a school routine or enjoying a holiday schedule. There's no evidence that you need to make major adjustments to insulin settings when moving between these two periods.

The research also underscores the value of good sleep habits. If your family is working to improve blood sugar outcomes, prioritizing consistent, adequate nighttime sleep is worth attention alongside technology and daily routines.
