Bedroom HEPA filtration linked to smaller glucose fluctuations in prediabetes
A randomized month-long study of more than 150 adults with prediabetes compared bedroom HEPA air cleaners with sham filters. The researchers reported lower daily glucose variability and smaller post-breakfast rises with filtration; findings are being presented at the American Heart Association Scientific Sessions.
- Randomized comparison of real and sham bedroom filters
- Active filters reduced particle levels by 36%
- Glucose variability and breakfast peaks were lower
- Meeting results; long-term clinical effects remain unknown
Researchers at NYU Langone Health randomly assigned more than 150 adults with prediabetes and no known atherosclerosis in New York City to use a portable bedroom air cleaner or a sham device for about one month. Participants wore continuous glucose monitors for a week before and after four weeks of filtration. Indoor pollution levels were measured, and glucose patterns were analyzed, including changes around breakfast.
The active filters reduced tiny airborne particle levels by 36%. Compared with the sham-filter group, filtration was associated with an almost 8% reduction in daily glucose swings. The researchers also reported a 17% average decrease in excess glucose after breakfast and a 13% reduction in post-breakfast peak levels.
The results are being presented at a scientific meeting; the source does not provide a full paper or detailed between-group estimates. The study lasted only a month, and its findings may not apply to people with diabetes or to populations exposed to different pollution levels. Longer-term studies are planned to assess whether filtration affects progression to diabetes or cardiovascular outcomes. Funding came from the Doris Duke Foundation.
