Abstract

The analysis of nail nitrogen content reflected recent nutritional status. Therefore, estimation of nail nitrogen content has been previously reported in a small group of neonates ana school children. Nail samples were obtained from 52 economically middle and 21 low classes. The contents of nitrogen in their fingernails were determinded by micro-Kjeldahl method. Mean nail nitrogen content was $133.1{\pm}8mg/g$ in the middle class which is significantly higher than that of the low class $122.1{\pm}8mg/g$. The nitrogen contents of nails obtained in summer were found by analysis of variance and student's t-test to he lower than those obtained in winter.
