However, based on the body mass index parameter, the percentage of overweight patients (Body Mass Index (BMI) 30–34.9 kg/m2) and patients with class 1–2 obesity (BMI 35–45.9 kg/m2) was significantly higher in the CPT2DM group than in the CP group or in the Control group. Here, CP is linked to obesity due to melanocortin 4 receptor deficiency.
