BMI Overestimates Childhood Obesity Compared to Waist-to-Height Ratio, Study Sugges

Body Mass Index (BMI) was almost three times more likely to classify child as overweight as a waist circumfererance-to-height ratio, according to a new study.

Published in Obesity and endocrinologyThe study was based on a collaboration between the University of Eastern Finland and the Universitys of Bristol and Exteer in the Uk.

BMI and Weight-to-height indices are universally employed as markers of childhood obesity. However, BMI does not distinguish muscle mass from fat mass, and may missClassify child as overweight.

With regard to adult obesity, The lancet Commission on Obesity and the European Association for the Study of Obesity (Easo) Have recently recommended that obesity in adults in adults should not be diagnosed with bmi alone but cone As waist-to-height ratio. The UK National Institute for Health Care and Excellence has also recommended waist-to-height ratio as a tool to predict health expensks associated with Central AdiPosity in Children.

The present study is the largest follow-up Pediatric study comparing BMI and waist-to-height ratio in the world. The Study Included 7,600 Children Drawn from the University of Bristol’s Children of the 90s Cohort Who WHO WHO WHO WHO WHO WHO WHO WHO WHO WHO WHO WHO WHO

Of the 1,431 children classified as BMI-Overweight at Age 9 Years, 25% Had Waist-to-Height Ratio of High Fat, 11% Had Waist-to-HEGHT RATIO OF OXCESS FAT, and 64% HAD Waist-to-height ratio of normal fat, according to the cutpoints used in the study. However, of the 517 Children Classified as Having Waist-to-Height Ratio of High Fat, 70% Were BMI-Overweight, 24% Had BMI-Obesity, and only 6% Had Normal BMI.

Dual-energy x-ray absorptiometry (dexa) is considered the gold-standard for accurate body fat measuring; However, this expensive device is not universally available in primary health care. It was previously reported from the same data that waist-to-height ratio can assess body fat to a maximum of 85% Accuracy Compared to Dexa Results. The waist-to-height ratio cutpoints for high, excess and normal body fat used in this study ware development from earlier results in the same childless and adalesents.

In the present study, these waist-to-height ratio cutpoints were also external validated for type 2 diabetes prediction in 3,329 us adults. Waist-to-height ratio of high fat was associateed with Higher Odds of Predibates, Whist Waist-to-Height Ratio of Excess Fat Predicted Higher Odds of Types 2 Diabetes.

“Waist-to-height ratio is an affordable and universally accessible, accurate and precise tool for detecting high and more detecting high and Excess fat in children and adolesments,” Kays andrew AGO AGOO AGOO AGOO AGOO ANDALESCENTS and AdHELESCENTS Associate Professor (DOCENT) of Clinical Epidemiology and Child Health at the University of Eastern Finland. His EarLier Research has also shown that waist-to-height ratio predicts bot total body adiposity and central adiposity.

“Overweight and Obesity in Children and Adolescents Should not be diagnosed with BMI Alone, but count be confirmed with waist-to-height ratio where a dexa scan is lacking,” AGBAJE CONCLUDES.
