Background and aims The coronavirus disease 2019 (COVID-19) pandemic has affected people's lives including patients with Type 1 diabetes mellitus (T1DM). We aimed to investigate the impact of the COVID-19 lockdown on psychological status, self-management behaviors, and diabetes care maintenance among Saudi adults with T1DM using insulin pump therapy. Methods This cross-sectional study used a web survey to collect data on Saudi adults with T1DM who were treated in the specialized insulin pump clinic at King Abdulaziz Medical City-Jeddah, Saudi Arabia. We used the Patient Health Questionnaire-9 and General Anxiety Disorder-7 scales to measure depression and anxiety. Results Of the 70 patients who received the survey, 65 completed it. Overall, 23.1% and 29.2% of the patients reported moderate to severe and mild depression, respectively; 18.5% and 24.6% reported moderate to severe and mild anxiety, respectively. Compared with pre-lockdown, adherence to a healthy diet and regular physical activity decreased in 67.7% and 41.5% of the patients, respectively. Most patients maintained their adherence to insulin pump behaviors; frequent self-monitoring of blood glucose increased in 47% of glucometer users. Most patients benefited from phone visits or virtual education sessions, but 66.2% of the patients reported difficulty obtaining at least one type of insulin pump supply. Conclusions Promoting self-management behaviors and psychological wellbeing of patients with T1DM using insulin pump therapy is crucial during a lockdown. Telemedicine is a useful alternative to in-person appointments, but strategies to ensure that patients have access to adequate resources during lockdown must be developed.

In subjects with NGT, fasting serum IGFBP-1 could be used as a simple reliable marker of insulin sensitivity. For more accurate estimation of insulin sensitivity in normal subjects and those with IFG, ln-transformation is preferred over raw data.
