Association between relative fat mass and obstructive sleep apnea and the potential mediating effect of hypertension: based on NHANES 2005-2008 and 2015-2018.

ABSTRACT:

Background

Obesity has been identified as one of the contributing factors to obstructive sleep apnea (OSA). The current obesity assessment indicators have poor ability to distinguish between fat and muscle. Relative fat mass (RFM) a new indicator of obesity that takes into account gender differences and can predict body fat conditions has advantage in this respect. This study aimed to investigate the potential association between RFM and OSA, as well as the possible mediating effect of hypertension.

Methods

This cross-sectional study used data from the National Health and Nutrition Examination Survey conducted in 2005-2008 and 2015-2018. Multivariate logistic regression, restricted cubic splines (RCS), and subgroup analyses were performed to evaluate the association between
