Use of Mindex and Demiquet for assessing nutritional status in older adults.

Abstract

The Mini Nutritional Assessment (MNA) is a validated questionnaire that estimates nutritional status. Given that this questionnaire uses stature measurement, which are unreliable in older adults, Mindex and Demiquet are alternatives to BMI for assessing malnutrition risk. However, the correlation of Mindex and Demiquet values with MNA scores has not been investigated. This cross-sectional study examined the correlation of Mindex and Demiquet with nutritional status and blood parameters in older adults in Thailand. The correlation of Mindex and Demiquet with MNA scores and body mass index (BMI), as well as blood parameters, was evaluated. Sociodemographic characteristics, anthropometric measurements, and blood test results were collected from 347 participants aged 60 years and older (mean ± SD, 66.4 ± 5.3 years). Spearman's rank correlation coefficient and multiple logistic regression analyses were used in statistical analyses. MNA scores were significantly correlated with Mindex (P < 0.001) and Demiquet (P = 0.001), and BMI was related to Mindex and Demiquet (P < 0.001). Low-density lipoprotein cholesterol (LDL-C) predicted MNA scores (P = 0.048) in males but not females. Mindex and Demiquet values were positively correlated with MNA scores and BMI. In addition, LDL-C predicted MNA scores in male older adults.
