 The use of mobile health technologies has been necessary to deliver patient education to patients with diabetes during the COVID-19 pandemic. The objective of this study was to evaluate the effects of a diabetes educational platform, Taipei Medical University line-oriented video education, delivered through a social media app. Patients with type 2 diabetes were recruited from a clinic through physician referral, and the social media-based program included 51 videos, 10 about understanding diabetes, 10 about daily care, 6 about nutrition care, 21 about diabetes drugs, and 4 containing quizzes. The intervention group received 2 or 3 videos every week and care messages every 2 weeks through the social media platform for 3 months.
