Anthropometric Somatotype among the Adolescent Boys of a Tribal Population in India

This study aimed to determine the somatotype and BMI, as well as investigate the somatotype variations in relation with age and BMI among the adolescent boys of Mising tribe. A cross-sectional sample of 278 adolescent boys was collected from five villages of Dhemaji district of Assam, a state in northeast India. Body mass index (BMI) was calculated for each subject. Heath-Carter method of somatotyping was employed to evaluate the somatotype characteristics of Mising adolescent boys. Descriptive statistics for all the ten anthropometric measurements employed in somatotyping show increasing trend with age. The mean BMI was found to be 18.37 kg/m2. The mean somatotype of the individuals was 1.46-3.81-3.3. Our findings showed mesomorph-ectomorph as the dominant type among the Mising boys. The somatoplots of mean somatotypes fall in the mesomorph-ectomorph at age 10+ to 15+ years, and from age 16+ to 18+ years the somatoplots were distributed in the ectomorphic mesomorph category. The age-wise comparison was tested using t-test. Results revealed that BMI values were found gradually increasing with age. Significant variations were observed in endomorphy and ectomorphy. Endomorphy tends to increase with age whereas ectomorphy tends to decrease with the advancement of age in a fluctuating pattern. Somatotype variations in relation with BMI presented significant values.
