Classification and Severity Assessment of Obesity in Clinical Risk Prediction of Multimorbidity Trajectories.

Waist-to-hip ratio (waist-to-hip ratio) and waist-to-height ratio (waist-to-height ratio) are better at capturing fat distribution than body mass index (BMI) and may have a role in obesity related multimorbidity prediction.

Subgroup analyses evaluated whether high central obesity (waist-to-height ratio ≥ 0.6) provided additional risk stratification within BMI groups.

However, BMI-stratified subgroup analyses, central obesity provided additional risk discrimination only among individuals in the overweight category (BMI 25-29.9 kg/m 2 ), but not among those with BMI ≥ 30 kg/m 2 .
