Outcome Measures

Primary Outcomes (1)

  • Cumulative incidence of Diabetes Mellitus after randomization

    Definition of "incidence of Diabetes Mellitus" * Fasting Glucose ≥126 mg/dL or * 75g Oral glucose tolerance test 2 hours after the Blood glucose ≥ 200 mg / dL or * HbA1c≥6.5%

    36 months from the baseline

Secondary Outcomes (4)

  • Change on HbA1c

    12, 24, 36 months from the baseline

  • Change on Fasting Glucose

    12, 24, 36 months from the baseline

  • Change on HOMA2%S

    12, 24, 36 months from the baseline

  • Change on HOMA2%B

    12, 24, 36 months from the baseline

Study Arms (3)

Conventional Management

NO INTERVENTION

A patient will receive 30 minutes of individual education from the investigator, based on the standard guidelines of the Korean Diabetes Association. And will be followed up every 6 months for 36 months.

Life style modification

EXPERIMENTAL

Proceed according to the Intervention Protocol developed by the Nutrition Committee of the Korean Diabetes Association. Aim to lose more than 5% of weight within 6 months, and then aim to keep weight loss constantly. After randomization, the diabetes educator team (physician / nurse / dietician) applies the intervention program for exercise therapy and diet therapy, and manages it through online education (telephone visit) and offline education (institution visit). * Exercise: Moderate or abnormal exercise for more than 150 minutes per week (moderate or abnormal exercise for 30 minutes or more per day) * Diet remedies: Train Calorie intake, nutrient intake and Monitoring.

Behavioral: Exercise and Diet remedies

Metformin

ACTIVE COMPARATOR

After randomization, take 250 mg once a day for 2 weeks. If there is no side effect, take 500 mg once a day for 2 weeks. If there are no side effects, the maximum dose can be increased to 1000mg.

Drug: Metformin

Interventions

Life style modification
Metformin
