Association between age-adjusted visceral adiposity index and obstructive sleep apnea: a study based on NHANES 2015-2018.

ABSTRACT:

Background

Obstructive sleep apnea (OSA) is a common sleep disorder that significantly impairs sleep quality and daytime functionality, with a well-established association with obesity. To enhance the precision of OSA risk assessment, this study introduces the age-adjusted visceral adiposity index (AVAI) and investigates its association with OSA.

Methods

The study utilized data from the 2015-2018 National Health and Nutrition Examination Survey (NHANES). The association of AVAI with OSA was examined through a multivariate logistic regression model. Propensity score matching (PSM) was leveraged for mitigating baseline characteristic imbalances and validating the robustness of the findings. Interaction and subgroup analyses were conducted to explore potential effect modifiers.
