ClinConnect Summary

This clinical trial is examining factors that could increase the risk of developing diabetes, specifically Type 2 Diabetes (T2D). The researchers want to understand how certain health conditions and characteristics might affect blood sugar levels. To take part in this study, participants must be between 40 and 65 years old and meet specific health criteria based on their blood sugar levels. For instance, healthy individuals should have a hemoglobin A1c (HbA1c) level of 5.6% or lower, while those with prediabetes or diabetes have slightly higher levels.

Participants in this trial can expect to provide information about their health and undergo regular check-ups to monitor their blood sugar. It’s important to know that certain health issues, medications, or recent participation in other studies may disqualify someone from joining. The trial is currently not recruiting participants, so it may take some time before it begins. Overall, this study aims to identify key risk factors for diabetes, which could help in preventing or managing the condition in the future.
