INS and obesity due to melanocortin 4 receptor deficiency: Age (r: 0.23, p = 0.05), measurements of obesity (weight (r: 0.51, p < 0.0001), BMI (r: 0.44, p < 0.0001), WHtR (r: 0.26, p = 0.02)), and markers of insulin resistance (fasting insulin levels (r: 0.28, p = 0.02), HOMA-IR (r: 0.25, p = 0.04)) were positively correlated with AS in the overall population.
