Objectives It is significant to determine the validation of a self-administered somatotype drawing for the simple assessment of childhood obesity in elementary school and clinical practice. Methods The subjects were 202 children(112 boys and 90 girls) who answered a questionnaire for somatotype drawing and weremeasured for body components with bioelectrical impedance. The somatotype drawing of children was analysed according to the three criteria of childhood obesity - BMI percentile, obesity index and percent body fat, respectively. Results BMI, waist-hip ratio, skeletal musclemass and proteinmass had significant differences(p<.05) between boys and girls. Somatotype drawing had the highest correlation with BMI in both boys and girls, and also showed a high correlation with BMI percentile, obesity index and percent body fat.According to these criteria of childhood obesity, the somatotype drawing was the best consistent with the obesity index, next turn was the percent body fat and then the BMI percentile. Conclusions The validation of somatotype drawing for the assessment of childhood obesity was analysed according to BMI percentile, obesity index and percent body fat, and the somatotype drawing was the best consistent with obesity index in both boys and girls.

Purpose: Somatotype drawing developed by Sorensen et al.(1983) has been evaluated as a simple instrument of obesity level without real somatic measuring as height and weight. This study was designed to validate somatotype drawings for obesity assessment by bioelectrical impedance body component analysis. Method: At first questionnaire of somatotype drawing was done. Subjects were measured body component by bioelectrical impedance analysis as weight, BMI(body mass index), WHR(waist-hip ratio), body water, protein mass, mineral mass, body fat mass, skeletal muscle mass, soft lean mass, fat free mass and percent body fat. We evaluated correlations between these data and somatotype drawings and tried to grouping of somatotype drawings with the means of major body component value. Result: The data were collected from 205 college women whose height and weight were $161.2\pm4.8,\;55\pm8.3$. Spearman's correlation coefficients of somatotype drawing were 0.74 with BMI, 0.68 with weight 0.69 with body fat mass, 0.65 with WHR. 0.64 with percent body fat after adiusted age. The grade of somatotype drawings were grouped as 1-2, 3-4, 5-6. 7-9 by BMI, body fat mass, weight, 1, 2-4, 5-6, 7-9 by WHR and 1-2, 3-4, 5-9 by percent body fat(ANOVA and Duncan's method). Conclusion: So quick instrument using somatotype drawings were useful tools for evaluation of obesity level and is applicable to screen degree of body fat in self-administered questionnaire survey.
