Prof. David O’Neal Presents New Findings on Meal Announcement Practices at ATTD Asia 2025
We would like to congratulate Prof David O’Neal for his presentation at the Advanced Technologies & Treatments for Diabetes (ATTD) Asia conference in Singapore, regarding novel research findings from a study on meal announcement practices in asia pacific countries (APAC).
CareLink Personal data from 780G users in APAC were analyzed until JUN2025. An algorithm, trained on CGM and insulin data, was able to identify meals as ‘on time’ (meal detected, bolus at or close after detection), ‘late’ (meal detected, bolus up to 90 minutes after detection), ‘missed’ (meal detected, no bolus), or ‘undetected’ (no meal detected, bolus given). Meal announcement practices and glycemic outcomes were summarized for the overall APAC region and by country (only those with N>100). Only adults aged 29–42, 43–55, and ≥56 years (per self-reported age group) were included, as the algorithm was adult-specific.
A total of 11,013 users from 10 countries were analyzed. The figure illustrates meal announcement practices by geography, revealing notable differences between countries. Japan and India stood out with a high percentage of on-time meal announcements (39.9% and 38.4%, respectively) as well as a low rates of missed meals (23.0% and 20.5%). These two countries also showed the relative high Time in Range (TIR), at 74.6% for Japan and 74.9% for India (not statistically tested).
In conclusion, real-world evidence from 780G users showed differences in meal announcement practices across APAC. Countries with high rates of on-time and low rates of missed meal announcements also showed high TIR. Whether this relationship is causal requires further investigation.
