Dataset Title: T1D-UOM – A Longitudinal Multimodal Dataset of Type 1 Diabetes

Overview

This dataset contains historical Type 1 Diabetes data collected across 16 individuals, covering activity data, blood glucose data, sleep data, insulin data, and nutrition Data. The data was collected in 2023 and 2024.

This dataset aims to support the development of algorithm in enahcning blood glucose management for people with Type 1 Diabetes Mellitus.
