A systematic literature search was conducted in PubMed/MEDLINE, Google Scholar, DOAJ, and the Cochrane Library according to PRISMA 2020 guidelines. Only studies that used validated instruments to measure depression, anxiety, and QoL in adult patients with type 1 or type 2 DM were included.

QoL scores were consistently reported as being significantly negatively related to depression and anxiety across studies. Included data demonstrated strong negative correlations between wellbeing scores and depression (p=-0.579) and anxiety (p=-0.632). Significant inverse correlations between depression and QoL (r=-0.690, p
