Nutritional status of elderly and its association with the degree of cognitive decline

Abstract

s / Clinical Nutrition ESPEN 13 (2016) e55ee74 e64 Materials and methods: In 699 healthy adults (436 women, 273 men) of 18 to 75 years old weight, height, body circumferences and body skinfolds measurements were obtained. Five simple noninvasive models estimating %TBF were examined, based on the mentioned measurements. Dual Xenergy Absorptiometry (DXA) was the reference method. The validity and reliability of each method was determined with Bland Altman Test and Intraclass Correlation Coefficient. Results: Mean %BFDXA was 35.2% and 22.9% for women and men respectively. Waist circumference was found to correlate with %BFDXA more than any other anthropometric measurement, both for women (r1⁄40.794, p<0.01) and men (r1⁄40.826, p<0.01). Regarding the evaluated models, % BFDEURENBERG was found to have a relative low bias (0.04%, p1⁄40.831 and limits of agreement1⁄4± 10.78) and high reliability (ІCC1⁄40.919). Conclusions: Among the five simple noninvasive models, only the one of Deurenberg et al, was found to be valid and reliable in estimating %BF. Development of noninvasive and low cost models estimating body composition customized for Greek population is considered to be necessary. Furthermore, the results of this study suggest the use of waist circumference in such models.
