Wednesday, February 4, 2015

PLAINSBORO, N.J. – Oh the irony. CPAP use could cause an increase in body mass index (BMI) in users who are heavier, according to a new study from the University of Massachusetts Medical School in Worcester. Study author Dr. Frank Domino reviewed medical literature of controlled trials for more than 3,000 patients. After adjusting for, among other things, age, gender, baseline BMI, baseline weight, OSA severity and CPAP compliance, he found that a high baseline weight could predict an increase in BMI or an increase in weight. Domino said future study is needed.
