Healthy lean control group

The healthy lean controls consisted of age-, sex- and geography-matched young volunteers, or "golden standard" lean controls from China Cardiometabolic Disease and Cancer Cohort Study (4C Study). Healthy volunteers: 1. BMI:18.5-22.9kg/m2; 2. Age:14-30 years old; 3. To be proved normal by the examinations of liver and kidney function,blood lipids profile,FBG, PBG, fasting insulin and HbA1c. Controls from 4C Study: 1. 17.0≤BMI≤23.0kg/m2 and waist circumference \<85cm for males and \<80cm for females; 2. 1.8≤LDL-c≤3.4mmol/l; 3. FBG\<6.1, PBG\<7.8; 4. HOMA-IR\<2.5; 5. BP \<140/90mmHg; 6. eGFR\>60mL/(min·1.73 m2), ALT\<40IU/L, AST\<40IU/L; 7. Excluding the history of hyperthyroidism, digestive system diseases, malignant tumors, infectious diseases (hepatitis B) and other systemic wasting diseases; Severe dysfunction of heart, lung and kidney; 8. Not using antihypertensive, hypoglycemic and lipid-lowering drugs; 9. No history of smoking.
