dc.description.abstract<p>Aim: Body mass index (BMI) metrics are widely used as a proxy for adiposity in children with severe obesity. The BMI expressed as the percentage of a cut‐off percentile for overweight or obesity has been proposed as a better alternative than BMI&nbsp;z‐scores when monitoring children and adolescents with severe obesity.</p> <p>Methods: Annual changes in BMI, BMI&nbsp;z‐score and the percentage above the International Obesity Task Force overweight cut‐off (%IOTF‐25) were compared with dual‐energy X‐ray absorptiometry (DXA) derived body fat (%BF‐DXA) in 59 children and adolescents with severe obesity.</p> <p>Results: The change in %BF‐DXA was correlated with the change in %IOTF‐25 (r&nbsp;=&nbsp;0.68) and BMI (r&nbsp;=&nbsp;0.70), and somewhat less with the BMI&nbsp;z‐score (r&nbsp;=&nbsp;0.57). Cohen's Kappa statistic to detect an increase or decrease in %BF‐DXA was fair for %IOTF‐25 (&kappa;&nbsp;=&nbsp;0.25; p&nbsp;=&nbsp;0.04) and BMI (&kappa;&nbsp;=&nbsp;0.33; p&nbsp;=&nbsp;0.01), but not for the BMI&nbsp;z‐score (&kappa;&nbsp;=&nbsp;0.08; p&nbsp;=&nbsp;0.5). The change in BMI was positively biased due to a natural increase with age.</p> <p>Conclusion: Changes in the BMI metrics included in the study are associated differently with changes in %BF‐DXA. The BMI&nbsp;z‐score is widely used to monitor changes in adiposity in children and adolescents with severe obesity, but the %IOTF‐25 might be a better alternative.</p>eng
