Body adiposity indicators are associated to triglyceride/glucose index in community-dwelling older adults

Abstract

Background/Purpose: To investigate the association between different indicators of body adiposity and TyG in community-dwelling older adults. Methods: One hundred and fifty-seven older adults voluntaries in the present study. Height, total body mass, waist and hip circumference were used to obtain the body mass index (BMI) and 6 other indexes related to body fat, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), conicity index, and more recent anthropometric indicators such as the body roundness index (BRI) and the body shape index (ABSI). The linear regression technique adjusted for sex and age was used. The regression model adequacy was verified through the analysis of normality of the residues (Kolmogorov-Smirnov test with significance level of p <0.05), in addition to the visual inspection to identify extreme observations in the histograms of the residues. Results: The linear regression analysis indicated that all adiposity indicators were significantly associated with TyG. The residue analysis indicated a good fit of the regression models obtained for the TyG, which could be confirmed by the low standard error values of estimative. Waist Circumference, WHR, and WHtR were the predictors with the best regression parameters. Conclusion: Body adiposity indicators are significantly associated to TyG in community-dwelling older adults. Waist Circumference, WHR, and WHtR are simple and low-cost anthropometric indicators that seem to be promising predictors of TyG, which could be candidate for future studies as screening tool for older adults prone to develop insulin resistance.
