ACCURACY COMPARISON OF ANTHROPOMETRIC FORMULAS OF HEIGHT ESTIMATION BASED ON SEVERAL LONG-BONES MEASUREMENT IN DEUTERO-MALAY ETHNIC

Abstract

Nutritional status can be assessed by knowing the height but because it is often difficult to quantify for example in bedrest patient or abnormal stature, it needs an alternative anthropometric measurement, such as height estimation based on long-bones measurement. Little information is available about the accuracy of these measurement, especially in deutero-malay ethnic. The present study aimed to compare accuracy for estimating height from several long-bones lengths to search an accurate anthropometric formula for nutritional status assessment. This study used an observational analytic method with cross sectional approach. The samples are students of Medical Faculty of University of Jernber that meet the inclusion and exclusion criteria. Data were analyzed with Kolmorgov-Smirnov test, Pearson Correlation test and linear regression. The method is by measuring height with microtoise and bones length with medline. The result showed strong and positive (r> 0.5) correlation between height and length of long-bones, so linear regression can be done. Among ulna, femur, humerus and radius bones, femur formula showed the highest accuracy both in men (rright = 0.904; left =0.906) and women (r right = 0.911; left = 0.900). We conclude that anthropometric formula from estimation of height by length of femur is the most accurate from all formula, thus the most preferable to be used for height estimation in deutero-malay ethnic when assessing nutritional status.
