Abstract
Background: Evidence shows that waist circumference (WC) is one reliable index to predict abdominal obesity in children. This study aims to examine the relationship of WC to other anthropometric indexes and to determine the ability of WC as obesity screening tool. Subjects: 811, 5-6 years old children in Saraburi province, central region of Thailand. Methods: Anthropometric measurements were performed in children; 406 boys and 405 girls. WC measurement was performed at the umbilicus level. Subcutaneous skinfold was measured on subscapular, suprailiac and abdominal regions. Total body fat was measured with bioelectrical impedance analyzer. Receiver operating characteristic (ROC) analysis was employed to determine WC cut-offs for predicting obesity in children. Results: WC highly correlated with weight-for-height Z-score (WHZ) (r= 0.92-0.94, p= 0.01), body mass index (BMI) (r= 0.95-0.96, p= 0.01), trunk skinfold (r = 0.92-0.93, p= 0.01) and total body fat (r= 0.94-0.95, p= 0.01) for both genders. Based on Thai national reference, the optimal WC cut-offs for predicting obesity were 59.6cm for boys and 60.5cm for girls. When IOTF-BMI was employed as reference, WC thresholds were 64.4cm for boys and 63.1cm for girls. The latter WC cut-offs provided the slightly underestimated obesity prevalence compared with national reference. Conclusion: The strongly positive correlation between WC and weight-height based index and between WC and body fat in Thai preschool children suggests that WC should be the additional index for obesity screening in young children. Further study needs to explore the association between the increased WC and other adverse health outcomes. © 2010 Asian Oceanian Association for the Study of Obesity. Published by Elsevier Ltd.
