Assess self-care activities, health behaviors, self-efficacy, diabetes distress, challenges, and changes in diabetes treatment and clinical parameters among Arabic-speaking people with T2DM during the COVID-19 pandemic.A cross-sectional study was conducted at a tertiary hospital in the United Arab Emirates. The study instrument collected self-reported data using validated tools about health behaviors, self-efficacy, and diabetes distress, and challenges in accessing and using healthcare services during the pandemic and documented clinical data and treatment before and during the pandemic from medical records.206 patients participated with a mean age of 58.7 years and 15.7 years since diabetes diagnosis. Non-adherence to healthful eating and exercise was reported by 38.3% and 73.7%, respectively. Exercise was the self-care activity that decreased the most (36.8%). Most participants had low diabetes distress (85.9%). There were no significant differences in clinical parameters before and during the pandemic, and diabetes treatment was unchanged for 72.8% of participants. Having two or more challenges with accessing and using diabetes healthcare services was significantly associated with decreased adherence to healthy eating (p = 0.025) and exercise (p = 0.003).Arabic-speaking people with T2DM appeared to maintain relatively similar self-care levels, except exercise, with no deterioration in clinical parameters compared to pre-pandemic.
