INS and diabetes mellitus: According to the results of multivariable logistic analysis poor glycemic control was more likely to occur among unemployed (AOR = 4.998, 95% CI = 2.579–9.688, p < 0.001), patients with no family/social support (AOR = 2.547, 95% CI = 1.131–5.733, p = 0.024), duration of diabetes >10 years (AOR = 6.359, 95% CI = 1.740–23.242, p = 0.005), poor knowledge about diabetes (AOR = 4.222, 95% CI = 1.378–12.932, p = 0.012), taking insulin (AOR = 3.359, 95% CI = 1.471–7.675, p = 0.004), taking metformin plus glibenclamide (AOR = 12.887, 95% CI = 3.184–52.158, p < 0.001) (Table 3).
