Relación de los índices de adiposidad visceral (VAI) y disfuncional (DAI) con parámetros de obesidad / Visceral adiposity index (VAI) and dysfunctional adiposity index (DAI). Relationship with obesity parameters

Introducción La obesidad es una pandemia mundial con repercusión en morbilidad y mortalidad crecientes. Valoramos la fortaleza asociativa del índice de adiposidad visceral (VAI) y del índice de adiposidad disfuncional (DAI) en obesidad y riesgo asociado utilizando diversos métodos. Material y métodos Estudio transversal en 418.343 trabajadores de diferentes comunidades autónomas en España, estimando prevalencia de obesidad con: perímetro de cintura, Índice cintura/altura, IMC, CUN-BAE, ECORE-BF, RFM, Palafolls, IMG, METS-VF calculados ajustándose a sus fórmulas específicas. Se realizó análisis descriptivo de las variables categóricas y fortaleza asociativa de VAI y DAI para obesidad con curvas ROC considerando riesgo elevado cuando el valor AUC.0,8 y moderado con AUC.0,7 y.0,8. Se utilizó SPSS 27.0, considerando significación estadística p.0,05. Resultados La prevalencia de obesidad varía según el método utilizado, siendo alta con Palafolls (72,92% en mujeres y 86,98% en hombres) y baja con METS-VF (1,31% en mujeres y 8,54% en hombres). Los valores medios de VAI y DAI son siempre superiores en hombres. El AUC de la curva ROC para VAI fue alta con METS-VF: en mujeres 0,836 (intervalo de confianza del 95% [IC 95%] 0,829-0,843), en hombres 0,848 (IC 95% 0,845-0,850) y con perímetro de cintura en hombres: 0,819 (IC 95% 0,816-0,822). DAI fue alto para METS-VF en mujeres: 0,809 (IC 95% 0,801-0,817). Conclusiones La prevalencia de obesidad y riesgo relacionado difiere según el método de valoración utilizado. VAI muestra alta fortaleza asociativa en obesidad y masa grasa para METS-VF en ambos sexos y con perímetro de cintura en hombres; DAI para METS-VF en mujeres (AU)

Introduction Obesity is a global pandemic with a growing impact on morbidity and mortality. We assessed the associative strength of the Visceral Adiposity Index (VAI) and Dysfunctional Adiposity Index (DAI) in obesity and associated risk using different methods. Material and methods Cross-sectional study in 418 343 workers from different autonomous communities in Spain, estimating prevalence of obesity with: waist circumference, waist/height index, BMI, CUN-BAE, ECORE-BF, RFM, PALAFOLLS, IMG, METS-VF calculated according to their specific formulas. Descriptive analysis of categorical variables and associative strength of VAI and DAI for obesity was performed with ROC curves considering high risk when the AUC value.0.8 and moderate with AUC.0.7 and.0.8. SPSS 27.0 was used, considering statistical significance p.0.05. Results The prevalence of obesity varied according to the method used, being high with Palafolls (72.92% in women and 86.98% in men) and low with METS-VF (1.31% in women and 8.54% in men). The mean values of VAI and DAI are always higher in men. The AUC of the ROC curve for VAI was high with METS-VF: in women 0.836 (95%CI 0.829-0.843), in men 0.848 (95%CI 0.845-0.850) and with waist circumference in men: 0.819 (95%CI 0.816-0.822). DAI was high for METS-FV in women: 0.809 (95%CI 0.801-0.817). Conclusions The prevalence of obesity and related risk differs according to the assessment method used. VAI shows high strength of association with obesity and fat mass for METS-VF in both sexes and with waist circumference in men; DAI for METS-VF in women (AU)

INTRODUCTION: Obesity is a global pandemic with a growing impact on morbidity and mortality. We assessed the associative strength of the Visceral Adiposity Index (VAI) and Dysfunctional Adiposity Index (DAI) in obesity and associated risk using different methods. MATERIAL AND METHODS: Cross-sectional study in 418 343 workers from different autonomous communities in Spain, estimating prevalence of obesity with: waist circumference, waist/height index, BMI, CUN-BAE, ECORE-BF, RFM, PALAFOLLS, IMG, METS-VF calculated according to their specific formulas. Descriptive analysis of categorical variables and associative strength of VAI and DAI for obesity was performed with ROC curves considering high risk when the AUC value.0.8 and moderate with AUC.0.7 and.0.8. SPSS 27.0 was used, considering statistical significance p.0.05. RESULTS: The prevalence of obesity varied according to the method used, being high with Palafolls (72.92% in women and 86.98% in men) and low with METS-VF (1.31% in women and 8.54% in men). The mean values of VAI and DAI are always higher in men. The AUC of the ROC curve for VAI was high with METS-VF: in women 0.836 (95%CI 0.829-0.843), in men 0.848 (95%CI 0.845-0.850) and with waist circumference in men: 0.819 (95%CI 0.816-0.822). DAI was high for METS-FV in women: 0.809 (95%CI 0.801-0.817). CONCLUSIONS: The prevalence of obesity and related risk differs according to the assessment method used. VAI shows high strength of association with obesity and fat mass for METS-VF in both sexes and with waist circumference in men; DAI for METS-VF in women.
