Abstract
A cross-sectional sample of 2987 children in the age group of 1 to 10 years were selected from urban slums of Delhi for measurement of weight and height. Males and females were 53 and 47% respectively. Mean weight and height were calculated for both the sexes. Comparison of percentiles of weight and height with NCHS and ICMR standards showed that the 75th percentiles weight and height of the present study were comparable with 80 and 90% of 50th percentile of NCHS respectively. Hence, upper 25% of the sample arranged in ascending order of magnitude were used for the construction of reference standards of weight and height. Comparison of percentiles drawn from the top 25% of the sample demonstrated that 50th percentile of the present study corresponded to 80% of 50th percentile of the NCHS for weight and 90% of 50th percentile of NCHS of the height for both boys and girls. Also the 50th percentile of ICMR for weight and height for both the sexes. Standards constructed from such sample would be better suited for two important uses: (i) monitoring of Nutrition Programme, and (ii) to detect a child with abnormal growth at the earliest.
