We assesed the relationship between depression and diabetic control using the Self-Rating Questionnaire for Depression (SRQ-D) in 174 diabetic patients. The subjects were divided into 5 groups according to their HbA
1c level. The groups with HbA
1c values from 5.8% to 6.5% and from 6.5% to 7.0% showed significantly lower SRQ-D scores. Terfore, we defined the groups with HbA
1c values from 5.8% to 7.0% as “moderately well controlled groups” and the remaining as “poorly controlled groups”. Furthermore, the sex, age, diabetes type, insulinuse, obesity and number of oral tablets consumed daily were also found to be related to the presence/absence of depression. Stepwise multiple regression analysis was performed using these 7 parameters, and diabetic control, sex, age, obesity and number of oral tablets consuned daily were found to be significant independent variables related to depression. In conclusion, it was revealed that sex, age, obesity, number of oral tablets consumed daily and diabetic control were related independently to the presence/absence of depression. It is, therefore, important to examine the patiens paying careful attention to the features described above.
