What the research found
Study (observational, conference). Dominic Ehrmann of FIDAM, Bad Mergentheim, and colleagues will present PRO-MENTAL analyses at the EASD meeting in Milan (ScienceDaily 28 September 2026). Four hundred adults (72% type 1 diabetes, 28% type 2; 55% women; median age 47, range 32–63; mean HbA1c 7.6%) wore continuous glucose monitors and rated daily quality of life for 14 days with a WHO-5 ecological momentary assessment. More time in 70–140 mg/dl on one day lined up with a better quality-of-life score the next day. Higher-than-usual glucose variability on the prior day also lined up with a better next-day score, which the authors read as a possible cost of trying to flatten every swing. Time above 180 or below 70 mg/dl the previous day did not predict next-day scores. Better sleep and higher energy the day before also predicted better scores. Same-day glucose numbers did not match same-day scores. Models accounted for age, sex, diabetes type, and prior-day scores. Conference data are preliminary. Educational notes. This does not license looser glucose targets.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
