Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study examines how menstrual cycle phases affect glycemic control and insulin requirements in women with type 1 diabetes (T1D). It aims to analyze differences in insulin needs and glucose levels between follicular and luteal phases using data from the Tidepool Data Platform. Key parameters include mean glucose, Time in Range (TIR), and total insulin administration. Secondary objectives involve assessing phase-specific glucose fluctuations, aggregated differences, and insulin adjustment strategies. The study follows a decentralized, anonymous data collection approach with participants using CGMs and insulin pumps or smart pens. Statistical analysis includes linear mixed-effects modeling to compare glycemic variability across cycle phases. Findings aim to enhance our understanding of diabetes management during the menstrual cycle and potentially inform future treatment strategies.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Single Arm

The study cohort consists of women with type 1 diabetes (T1D) who use continuous glucose monitoring (CGM) and insulin pumps to manage their diabetes. Participants will anonymously upload their glucose and insulin delivery data, along with self-reported menstrual cycle information. The study focuses on analyzing variations in insulin requirements and glycemic control across menstrual cycle phases, without introducing any direct interventions.

No interventions assigned to this group
