When stepwise multiple regression analysis was applied with HbA1c level as the dependent variable and the independent variables being the geographic region of the country, duration of diabetes, insulin regimen, age, economic status, daily frequency of SBGM and gender, it was shown that low/very low economic status, (r=0.10, r2=0.01, and B=0.22; p < 0.001), daily frequency of SBGM (r=0.14, r2=0.02, and B=−0.13; p = 0.001), female gender (r=0.16, r2=0.02, and B=0.40; p < 0.001) and age (r=0.17, r2=0.03, and B=−0.013; p< 0.001) were associated with HbA1c levels. Here, INS is linked to diabetes mellitus.
