SOMATOTYPE AND BODY IMAGE AS PREDICTORS OF OVERALL AND ABDOMINAL OBESITY IN COLLEGE STUDENTS FROM NORTHERN MEXICO
Objective: To maximize somatotype and body image to predict overweight/obesity and abdominal obesity in college students from northern Mexico.
Methods: Body Mass Index (BMI), Waist Circumference (WC), somatotype and Body image (BI) from 329 undergraduate college students (17-35 years; 51% male) were obtained. Sensitivity, specificity, precision and accuracy of anthropometry, somatotype and BI stratification, were estimated using ROC curves and classification/regression trees analysis.
Results. Average BMI was 24±4 (male) and 25±5 (female) while WC was 79±9 (male) and 81±10 (female). Somatotype predicted BMI & WC by 93.5% and 89.8% while BI by 82.6% and 87.4%, respectively. Ectomorphy and BI were strong predictors of unhealthy individuals. Endomorphy-Mesomorphy-Ectomorphy values above of 5.35-4.75-1.25 or a BI above of 3.5 predicted an unhealthy BMI, while 6.55-5.45-1.15 or a BI 4.5 an unhealthy WC and thin-idealization.
Conclusions: Somatotype and body image are useful measures to predict overall and abdominal obesity in Mexican college students.
