Depression and Anxiety Among Individuals Receiving Incretin Mimetic Medications: A Saudi Cross-Sectional Study

Depression and anxiety are prevalent mental health disorders that substantially impact quality of life. The association of incretin mimetics, including glucagon-like peptide-1 (GLP-1) receptor agonists, with symptoms of depression and anxiety remain underexplored in Saudi Arabia. This study was conducted to assess the association between GLP-1 receptor agonist use and symptoms of depression and anxiety and to identify related factors.

A cross-sectional study using convenience sampling was conducted among adults (≥18 years) treated with GLP-1 receptor agonists at King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia. Data were collected using a questionnaire developed by the research team, in addition to the Arabic versions of the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7).

A total of 235 participants were included, of whom 48.5% used GLP-1 receptor agonists for both glycemic control and weight loss. Only 31.9% had undergone psychiatric evaluation prior to initiating therapy, and 14.9% had a diagnosed psychiatric disorder. The mean anxiety score (GAD-7) was 4.82 ± 5, and the mean depression score (PHQ-9) was 6.13 ± 4.95. Multivariable analysis showed that higher odds of more severe depression were associated with using diabetes medications for weight loss in addition to diabetes treatment, a history of psychiatric disorders, and holding a bachelor's degree. Exercising for 101-150 min per week was associated with lower odds of depression. Regarding anxiety, participants who exercised 101-150 min per week had significantly lower odds of anxiety compared with those who did not exercise, while a history of psychiatric disorders was associated with higher odds of more severe anxiety.

This study's findings highlight the importance of integrating both routine psychiatric screening and follow-up into diabetes and obesity management to enhance both psychological well-being and metabolic outcomes. They also reflect the benefit of physical activity for mental health, emphasizing the need to encourage exercise among individuals with diabetes or obesity.
