Low serum creatinine predicts risk for type 2 diabetes

Area of Science:

• Endocrinology
• Metabolic Diseases
• Clinical Biochemistry

Background:

• Skeletal muscle, an insulin target tissue, plays a role in type 2 diabetes mellitus (T2DM).
• Serum creatinine, a marker of muscle mass, is inversely associated with T2DM risk.
• Limited longitudinal data exists on the relationship between serum creatinine and T2DM incidence.

Purpose of the Study:

• To investigate the longitudinal association between serum creatinine levels and the risk of developing T2DM.
• To examine this relationship in a large, diverse general population sample.
• To determine if serum creatinine can serve as an early predictor for T2DM risk.

Main Methods:

• Prospective cohort study involving 57,587 participants in Tianjin, China.
• Follow-up duration ranged from 1 to 9 years (mean 3.57 years).
• Multivariable Cox proportional hazards regression models analyzed the link between baseline serum creatinine and T2DM incidence.

Main Results:

• A total of 2017 incident T2DM cases were recorded during follow-up.
• Lower serum creatinine levels were significantly associated with a reduced risk of developing T2DM (P for trend <.01).
• The inverse relationship between serum creatinine and T2DM risk was consistent in both men and women.

Conclusions:

• Serum creatinine concentration is inversely related to incident T2DM in both sexes.
• Serum creatinine measurement may aid in the early identification of individuals at high risk for T2DM.
• This finding supports the utility of serum creatinine as a potential biomarker for T2DM risk assessment.
