Adherence to insulin therapy was statistically associated with age (p = 0.020), marital status (p = 0.001), employment status (p = 0.012), type of DM (p<0.001), taking oral antidiabetic medication (p = 0.002), regular follow-up (p = 0.007) and comorbidities (p = 0.002) (Table 3). Here, INS is linked to diabetes mellitus.
