This study collected clinical data of obese patients with euthyroid function, including age, gender, height, weight, BMI, waist circumference, blood pressure, fasting blood sugar, blood sugar 2 hours after sugar load, fasting plasma high-density lipoprotein cholesterol, fasting three acyl glycerin, free iodine thyroid hormone (FT3) and free thyroid hormones (FT4), thyroid stimulating hormone (TSH), follow-up information and etc. Via analyzing the data, the investigators want to investigate the association between thyroid hormones (THs) and metabolic components in obese patients with euthyroid function and to present the cutoff values of THs in order to provide new information for the risk stratification of metabolic syndrome in obese patients with euthyroid function.

Inclusion Criteria:

• 1) age ranged from 18-65 years old, 2) BMI over 27.9kg/m2,3)TSH，FT4, and FT3 within the range of 0.38-4.34mIU/L, 10.5-24.4mIU/L, and 2.8-6.3mIU/L, respectively.

Exclusion Criteria:

• secondary cause of obesity such as hypothalamic obesity, Cushing syndrome, and hypophysis dysfunction, etc.,2)pregnancy or location, 3) severe heart, liver and kidney dysfunction

We enrolled obese patients with euthyroid function.

The individual participant data (IPD) are not available to other researchers.
