The purpose of this study was to examine age and sex variations in anthropometric characteristics among Muslim adolescents of North 24 Parganas, West Bengal. Eight hundred and sixty school boys (n=416) and girls (n=444) aged from 10 to 15 years participated in this study. The subjects were classified into six yearly age groups: 10-10.9 years (n = 56, 62), 11-11.9 (n = 63, 73), 12-12.9 (n = 65, 82), 13-13.9 (n = 77, 79), 14-14.9 (n = 84, 78), 15-15.9 (n = 71, 70). All the anthropometric variables were measured by the following standard anthropometric procedure as recommended by Lohman et al (1988). Girls were taller and heavier than boys from 10 to 14 years. Thereafter the trend was reversed. Boys were significantly (p < 0.05) shorter and heavier than ICMR (1996) standards but girls were significantly (p < 0.05) taller and heavier than ICMR standards.
