Depression was associated with female gender (p=0.04) and psychiatric family history (p=0.01). Patients with depression have had significantly higher HbA1c levels (p=0.05) and significantly lower HDL-C levels (p=0.05). Regarding psychosocial factors, depression was associated with low self-esteem (p= 0.005) and significantly higher scores of depressive (p=0.002) and cyclothymic (p=0.003) temperaments. Depression was also associated with significantly lower treatment satisfaction (p=0.01) and poor quality of life.
