The results showed that hypertension (OR = 7.272, 95% CI: 1.650–32.044, p = 0.009), albumin (OR = 1.147, 95% CI: 1.018–1.293, p = 0.024), fasting C-peptide (OR = 1.443, 95% CI: 1.066–1.955, p = 0.018) were three independent risk factors for obesity group (Table 4). This evidence concerns the gene ALB and obesity due to melanocortin 4 receptor deficiency.
