In recent years, there has been an increased interest in depression and diabetes risk factors. Our objectives were 1) Study the variables associated with the presence of depression in patients with type 1 diabetes mellitus (DM1), 2) to analyze potential risk factors for depression in these patients, and 3) to study a possible explanatory model of depression scores in these patients. 207 patients with DM1. We evaluated sociodemographic and biomedical variables by means of a structured interview. We assessed psychological variables by means of the Scale for Depression in Type 1 Diabetes (EDDI-1) and the Spanish version of Diabetes Quality of Life (Es DQOL). Prevalence of depression was 21,7%. Variables associated with risk of depression in this sample were to be female; be unemployed; smoking; having complications of diabetes or other physical conditions; not perceiving family support or support from friends or colleagues in relation to diabetes; having a high number of weekly hyperglycemia; and a poor quality of life. A model based on previous research was obtained. This model explains a high percentage of the variability in the scores of patients in the EDDI-1. These results provide an empirical support to the knowledge of the risk factors associated with depression in patients with DM1. Glycemic control and quality of life have an important effect on the scores of depression in these patients, providing information for their treatment.
