Clinically significant changes in weight and fitness compared between BMI groupsa, b

a Overweight: BMI 25 to <30 kg/m2; Class I obesity: BMI 30 to <35 kg/m2; Class II obesity: BMI 35 to <40 kg/m2; and Severe Obesity: BMI ≥ 40 kg/m2

b The proportion of participants who achieved improved fitness determined as >50 meter and >80 meter increase on the 6-Minute Walk Test did not differ significantly between BMI groups.

* Participants with class I obesity were significantly less likely to achieve ≥5% weight loss compared to participants with severe obesity (OR=0.57; 95% CI=0.37–0.90).

** Participants who were overweight were significantly less likely to achieve ≥10% weight loss compared to participants with severe obesity (OR=0.21; 95% CI=0.08–0.52).

*** Participants with class I obesity were significantly less likely to achieve ≥10% weight loss compared to participants with severe obesity (OR=0.26; 95% CI=0.13–0.55).
