Key result
Increased waist-to-height ratio in overweight and obese adolescents was associated with worsened lipid profiles and increased odds of hypertension compared to those with normal WHtR.
Why the study?
Does the addition of waist circumference and waist-to-height ratio to BMI improve risk specification for lipid and blood pressure abnormalities in adolescents?
Population
3,248 grade 9 students (14- and 15-year-old), 51% male, from the Niagara Region, Ontario, Canada.
Comparison
Waist circumference percentile and… vs Body mass index (BMI) alone
Design
Cross-sectional

WHtR may refine cardiometabolic risk identification beyond BMI in adolescents; hypothesis-generating and requires prospective validation before practice change.

Does the addition of waist circumference and waist-to-height ratio to BMI improve risk specification for lipid and blood pressure abnormalities in adolescents?
Adding waist-to-height ratio to BMI assessment in overweight and obese adolescents improves the identification of those at higher risk for lipid abnormalities and hypertension.
Khoury et al. (2012) conducted a cross-sectional in Adolescents (n=3,248). Increased waist-to-height ratio (WHtR) and waist circumference vs. Normal WHtR and normal BMI was evaluated on Nonfasting lipid values and blood pressure categories. Increased waist-to-height ratio in overweight and obese adolescents was associated with worsened lipid profiles and increased odds of hypertension compared to those with normal WHtR.
