Abstract
Abstract Objective: to evaluate methods of elderly height estimation attended at the Nutrition ambulatory. Method: a total of 43 elderly individuals of both genders were evaluated during nutrition consultations. Sociodemographic data were collected from charts and height, knee height, arms wingspan and semi-span were measured. Statistical analysis were made through Bland-Altman test to evaluate concordance among statures estimated by predictive formulas and the height measured. Results: the values found were: height measured in meters 1.53 (±0.08), height estimated by the wingspan 1.60 (±0.10), by the semi-span 1.61 (±0.11) and by the knee height 1.56 (±0.10). According to the Bland-Altman graph, the height estimated by knee height showed a better agreement with the measured height. Conclusion: according to this study results, poor predictive formulas concordance in height estimation in elderly, using the measures: arms wingspan and semi-span with real stature measured were observed. Knee height, using Chumlea formula, presented the best concordance with measured stature and seems to be a good way for stature estimation at the studied population.

Objective: to evaluate methods of elderly height estimation attended at the Nutrition ambulatory
Depletion of carried out, comprising 43 elderly patients, aged skeletal muscle tissue associated with decreased ≥60 years, attended at the Nutrition Outpatient strength and functionality characterizes sarcopenia Clinic located at the Reference Center for Health in the elderly[3]
Regarding the methods of height estimating in elderly, after the statistical tests were applied, the results did not show good agreement in the measured stature and the estimated with arm span, where a variation of approximately 10 cm was found, being relevant in clinical practice, because if the predictive formula overestimates height, it would impact on estimated weight and, following errors on nutritional needs calculations[19]
Summary
Agreement between the methods of height estimates and the measured height of elderly patients attended. Nutritional status evaluation encompasses several methods and techniques, as anthropometric measures, specially body weight and height. This reduction in height is due to changes in spine during aging process[7] In these cases, there are several methods to estimate weight and height, among them, predictive formulas, using measures such as: knee height (KH), wingspan and semi-span to estimate stature[8]. Through estimated height and Body Mass Index (BMI), using the reference range of the World Health Organization (WHO), among other methods[9] These formulas are routinely used in clinical practice for anthropometric evaluation and nutritional needs calculation, the accuracy and precision of these are little known for Brazilian elderly[10].
