Primary Outcome Measures :
  1. Cardiovascular risk factors [ Time Frame: 6 months ]
    To compare the cardiovascular risk factors, including blood pressue, fasting blood sugar (FBS), Homeostasis Model of Assessment - Insulin Resistance (HOMA-IR), 75-g oral glucose tolerance test (75-g OGTT), lipid profile, high sensitivity C-reactive protein(hs-CRP), neck circumference and waist circumference, between metformin and plcebo at 6 months

Secondary Outcome Measures :
  1. 10-year risk of coronary heart disease [ Time Frame: 6 months ]
    To compare 10-year risk of coronary heart disease, which is calculated from RAMA- Electricity Generating Authority of Thailand (RAMA-EGAT) score, between metformin group and placebo at 6 months
