WE are recruiting potential eligible individuals of the Cohort!
- 22 June 2023
What is the SeDia Cohort?
The Seremban Diabetes (SeDia) Cohort is a disease cohort based in Malaysia to study the determinants of complications in individuals with Type 2 diabetes mellitus (T2DM). The SeDia Cohort is a collaborative partnership between the Ministry of Health (MOH), Malaysia and the International Medical University (IMU), Kuala Lumpur. This study aims to examine the roles of genetic, physiological, lifestyle and psycho-social factors in the development of T2DM and its complications. By having a better understanding of how the disease progresses to cause complications, we can contribute to the development of better care to prevent or delay diabetes-related problems.
The SeDia Cohort will focus on diabetic patients registered with the Diabetes Registry of Klinik Kesihatan Seremban, Negeri Sembilan and their family members. With the known genetic link in T2DM, family members of diabetic patients may also have a risk of getting the disease. Hence, adult family members residing in the same household will also be screened to determine if they have diabetes and help us better understand the risk factors for developing T2DM. Recruited patients and their household family members will be followed up every 3 years for a minimum duration of 12 years. Through the SeDia Cohort, we hope to provide a more comprehensive understanding of the causes and development of T2DM and its related complications, with the long-term objective of preventing and controlling diabetes.
