“…Moreover, agreement between the IOTF and WHO references and French references ranged from moderate (Kappa = 0.43) to perfect (Kappa = 1.00) among French children ( 40 ). However, in a group of South American children, moderate agreements were observed between body fat estimated by dual-energy x-ray absorptiometry (DXA) and by the IOTF (Kappa = 0.61) and WHO (Kappa = 0.63) references, with the IOTF cutoffs showing the highest specificity (0.98 [0.94, 0.99]) ( 41 ). Data from a study conducted with Italian children and adolescents aged 5–17 years indicated that the WHO references had the highest sensitivity, while the IOTF classification had the highest specificity, in identifying obese subjects with clustered cardiometabolic risk factors ( 42 ).…”

ObjectiveTo compare three body mass index (BMI) classifications that are used to assess the prevalence of overweight and obesity among Saudi children aged 6–13 years: the International Obesity Task Force (IOTF) age and gender cutoffs, the World Health Organization (WHO) growth references for school-aged children, and the Saudi (KSA) national growth references.MethodsThe sample comprised 2,169 children (52.5% girls) derived from two cross-sectional studies conducted in Riyadh and Jeddah during the 2017 and 2019 school years, respectively. Body weight and height were measured, and BMI was calculated.ResultsThe proportions (%) of the participants who were classified as underweight, overweight, and obese varied according to the reference used: IOTF reference (13.8, 18.4, and 12.7), WHO reference (17.2, 19.1, and 18.9), and KSA reference (7.0, 22.4, and 9.3), respectively, indicating higher values for overweight and obesity prevalence when the WHO references were used. Kappa agreement measures between the three references were found to be high, with the coefficients ranging from 0.936 (between the IOTF and KSA references) to 0.849 (between the IOTF and WHO references). In all three classifications, girls exhibited lower overweight or obesity prevalence than boys. Family income, but not paternal or maternal education, was significantly (p = 0.015) associated with overweight/obesity when using the IOTF standards. In addition, having a small family in the house was significantly (p < 0.05) associated with obesity, irrespective of the classification system.ConclusionInconsistency was observed when estimating the prevalence of underweight, overweight, and obesity among Saudi children. However, when defining the overall prevalence of overweight plus obesity among Saudi children, the IOTF classification system performed in a similar way to the KSA references (31.1% versus 31.7%) compared to the WHO references (38.0%).

Objectives Owing to increase in prevalence of obesity and metabolic syndrome in Indian children and adolescents, this study is conducted to assess the predictive value of IAP 2015 and WHO 2007 BMI for age cut-offs in identifying metabolic risk in Indian children. Methods Cross-sectional multicentric school-based study on 9–18-year-old healthy children (n=1,418) randomly selected from three states of India. Results WHO 2007 and IAP 2015 charts classified 222 (15.7%) and 271 (19.1%) as overweight/obese, respectively. A total of 192 (13.5%) subjects had metabolic risk. Of these 47 (25%) and 36 (18.75%) were classified as having normal body mass index (BMI) by WHO and IAP, respectively. In identifying metabolic risk, IAP 2015 and WHO 2007 charts showed a sensitivity of 81.3 and 75%, negative predictive value 96.5% as against 94.8%, positive predictive value 57.5 and 64.8%, and specificity of 89.7 and 91.6%, respectively. Conclusions Owing to obesity epidemic and high metabolic risk in Indians, IAP 2015 charts (as against the WHO 2007 references) which had a higher sensitivity in identifying metabolic risk may be more suitable in Indian children and adolescents.

Accuracy of different cutoff points of body mass index to identify overweight according to body fat values estimated by DEXA

Abstract: The cutoff proposed by Conde and Monteiro was more sensitive in identifying overweight and obesity when compared to the reference method, and the cutoff proposed by Cole et al. presented the highest specificity for such outcomes.
