Factors associated with poor glycemic control were obesity [odds ratio (OR)=1.9], DM duration between 5 and 10 years or more than 10 years (OR=1.8 and 2.5, respectively), and the use of a combination of oral hypoglycemic agent plus insulin or insulin alone (OR=2.4 and 6.2, respectively). Here, INS is linked to obesity due to melanocortin 4 receptor deficiency.
