SUMMARY
A comparison of two anthropometry methods for the estimation of frame size in Venezuelan adults
The frame size improves the interpretation of the body mass in adult and is incorporation is very useful in the assessment of nutritional status. This study compared two of the anthropometric methods used to classify individuals according to frame size: Grant method (height (cm) / wrist circumference (cm) and Frame index 2 (elbow breadth (mm)/height (cm) x 100) inorder to identify coincidence, concordance and divergence between then. Data from two hundred and forty nine, apparently healthy individuals, between the ages of 22 and 63, belonging to "Health Project: Administration employees of the Simón Bolívar University" were included. Results showed significant differences between the two methods, not only in the proportion of classified individuals in each frame size category, but also when contrasted the same method using one or another body hemispheres. When studying both methods, the divergence in frame size identification varied between 19% and 55% with a low concordance (k = = 0,40). Grant method, compared to Frame index 2 showed a greater association with the variables and indicators of total body mass and body fat; in the other hand, Frame index 2 revealed a lasser correlation with such variables and indicators specially in female (r =0,17 with fat percentage). These results clearly show the differences, that could be created in the frame size identification of an individual of group of individuals if different criteria are used; this could also lead to a wrong anthropometric diagnosis.

Key words: Anthropometric, body mass, assessment nutritional, frame size.
