Body Roundness Index Versus Body Mass Index: Differential Associations With Obstructive Sleep Apnea Syndrome and All-Cause Mortality in US Adults Aged 20 Years and Older.

ABSTRACT:

Background

Being obese considerably elevates the risk of both obstructive sleep apnea syndrome (OSAS) and mortality. Although body mass index (BMI) is a common measure, it neglects visceral adiposity, a critical factor in the development of cardiometabolic and respiratory dysfunction. By integrating waist circumference and height, the body roundness index (BRI) delivers a more accurate evaluation of central fat distribution, potentially improving the prediction of OSAS and mortality.

Methods

We analyzed data from 13,854 US adults aged ≥20 years from the NHANES 2005-2008 and 2015-2018 cycles. Using multivariable logistic and Cox regression models, along with restricted cubic spline and subgroup analyses, the connections of BRI and BMI with OSAS and all-cause mortality were ex
