A National Multicenter Prospective Cohort Study on the Incidence Characteristics and Risk Associations of Metabolic and Multi-system Comorbidities in Overweight and Obese Populations Stratified by Body Mass Index
This is a nationwide, multi-center, long-term follow-up study of overweight and obese adults in China. The study aims to recruit approximately 26,000 participants across 39 hospitals to better understand how body weight affects the development of obesity-related diseases over a 3-year period.
Eligible participants are adults aged 18 to 79 years with a body mass index (BMI) of 23 kg/m² or higher. Participants will be grouped into four categories based on their BMI: overweight, mild obesity, moderate obesity, and severe obesity.
At the beginning of the study, all participants will undergo a comprehensive health assessment, including physical measurements, body composition analysis, blood tests, and lifestyle questionnaires. Participants will then be followed for 3 years with annual check-ins to track any new health conditions.
The main goal is to identify the 3-year risk of developing conditions such as type 2 diabetes, fatty liver disease, high blood pressure, and heart disease in different weight groups. This information will help doctors better predict and prevent obesity-related health problems in the future.
Participation is voluntary, and all personal information will be kept confidential.
Inclusion: Adults aged 18 to 79 years; BMI ≥23.0 kg/m² (overweight or obese per 2026 ADA criteria); Able to provide written informed consent; Capable of completing baseline assessment and 3-year follow-up; Local residency for ≥3 years; Willing to provide fasting blood samples for storage.
Exclusion: Concurrent participation in other weight-loss or metabolic intervention trials; Secondary obesity (Cushing's syndrome, hypothyroidism, drug-induced or genetic obesity); End-stage severe chronic diseases (refractory heart failure, advanced malignancy, AIDS); Severe psychiatric disorders or cognitive impairment; Pregnancy or lactation.
