AI helper (Tia Bete) on WhatsApp to assist with carb counting and insulin dosing for people with type 1 diabetes

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, longitudinal interventional study testing the AI-based tool Tia Bete, which gives real-time carbohydrate-counting and insulin-dose recommendations via WhatsApp using personalized insulin-to-carbohydrate ratios and insulin sensitivity factors. Participants include children (6–18 years) with caregiver involvement and adults over 18 who are on a basal-bolus insulin regimen and have recent HbA1c between 7.2% and 10.5%. The protocol requires regular outpatient follow-up at the University of São Paulo and a minimum frequency of interaction with the tool during the study. Key exclusions include inability to use WhatsApp, illiteracy, failure to follow instructions, or interacting with the tool fewer than three days per week.
