Visceral adiposity index is associated with lung function impairment: a population-based study

Abstract Background The effects of visceral adiposity on decreased lung function have drawn much attention. Recently, the index (VAI) has been proposed as a fat distribution and dysfunction marker. However, relationship between VAI not investigated. objective study was to analyze association evaluate potential predictor function. Methods We collected data from population-based 1786 subjects aged 40 years or older. All completed questionnaire underwent anthropometric measurements laboratory tests. Linear logistic regression models were developed assess Results inversely related FVC%predicted in men negatively associated with both FEV1%predicted women. In linear analysis, decrease each 10% increase 1.127% 1.943% women; 10%increase 0.663% 1.738% Further analysis revealed that positively correlated FVC FEV1 impairment Conclusions first show clear correlation Chinese population. could be simple reliable approach daily practice, individuals, especially women high VAI, should receive additional screening preventive interventions for respiratory disease.
