Waist-to-height ratio bests BMI for predicting fat mass in children

Waist circumference-to-high ratio (WHtR) is an cheap alternative to body mass index (BMI) for predicting fats mass (FM) in pediatric sufferers, fixed with a look printed on-line March 5 in Pediatric Study.

Andrew O. Agbaje, M.D., Ph.D., from the University of Japanese Finland in Kuopio, examined agreement of surrogate measures of adiposity with dual-vitality X-ray absorptiometry-measured body composition. The analysis integrated 7,237 9-year-aged younger of us taking part within the Avon Longitudinal See of Folks and Kids, with 15-year phrase-up knowledge.

Agbaje found that for the length of phrase-up, BMI, complete FM, and trunk FM increased, nonetheless WHtR change into somewhat stable. Over time, WHtR supplied better absolute agreement with complete FM as successfully as trunk FM (males: intraclass correlation [ICC], 0.84; females: ICC, 0.81) when put next with BMI (males: ICC, 0.65; females: ICC, 0.72). For predicting excess complete FM (75th to 95thpercentile), the WHtR reduce point change into 0.50 to 0.53 in males (declare beneath the curve [AUC], 0.86 to 0.94; sensitivity: 0.51 to 0.79; specificity: 0.93 to 0.95). In females, the WHtR reduce point for predicting excess complete FM change into 0.52 to 0.54 (AUC, 0.83 to 0.95; sensitivity: 0.38 to 0.68; specificity: 0.92 to 0.95). For trunk FM, results were identical.

“This look affords recent details that would be precious in updating future childhood obesity pointers and policy statements,” Agbaje said in an announcement. “The average waist circumference-to-high ratio in childhood, youth, and younger adulthood is 0.45; it would no longer fluctuate with age and amongst people fancy BMI.”
