Association between visceral lipid accumulation indicator and preserved ratio impaired spirometry in US adults: a population-based study from 2007 to 2012.

ABSTRACT:

Background

Preserved Ratio Impaired Spirometry (PRISm) is a condition characterized by a forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio ≥ 0.70, yet FEV1 is below 80% of the predicted value. Recent studies suggest that visceral lipid accumulation may play a role in respiratory health, but the relationship between visceral fat indices and PRISm remains under explored. To investigate the relationship between indicators of visceral lipid accumulation and PRISm in US adults using data from the National Health and Nutrition Examination Survey (NHANES).

Methods

Data from three consecutive cycles of NHANES (2007-2012) were analyzed. Logistic regression and generalized additive models (GAM) were used to assess the relationship between various indic
