*p < 0.05

**p < 0.001. Estimates are adjusted for patient age, sex, and secular time (number of months between study initiation and the patient entering the study).

^aTo fulfil the physical activity recommendations, the patients had to report moderate-intensity activity for 150 minutes or vigorous-intensity activity for 60 minutes per week, or a combination of these.

^bOverweight: BMI ≥ 25 kg/m²; obese: BMI ≥ 30 kg/m².

BMI, body mass index; OR, odds ratio; T₀, baseline; T₃, 3-month follow-up; T₆, 6-month follow-up.
