Characterization and Mechanism Research of the Pre-disease State of Obese Type 2 Diabetes Mellitus

Overview

Establish a comprehensive evaluation system for the progression of obese impaired glucose tolerance (IGT) to type 2 diabetes mellitus (T2DM) through cross-sectional studies; Constructing and validating a T2DM risk prediction model for obese IGT population through observational research; Through open-label clinical research, we applied Jinlida granules to intervene in high-risk obese IGT population and clarify its protective effect on this population.

Interventions

• Drug 1/bag of Jinlida granules, 3 times/day, taken with hot water.
  All observation and intervention groups received lifestyle interventions, with only the intervention group of high-risk obese impaired glucose tolerance receiving intervention with Jinlida granules.

Primary outcome measures

• incidence of diabetes [Time frame: Both the observation group and the intervention group were followed up for 12 months, once a month.]
