The proposal aims to find neuroimaging correlates of obesity integrating multi-modal neuroimaging, genetic information, and relevant clinical factors. The proposal explores obesity in general population. The proposal explores neuroimaging correlates of obesity, which would eventually contribute to prevention, diagnosis and treatment obesity. Obesity is a major health problem in all corners of the earth. The proposal will consider participants of various levels of obesity. Mathematical/statistical models will be built using a different combination of neuroimaging, genetic, clinical information to predict the degree of obesity. Then, I would be able to answer what factors are important for obesity. A full cohort is needed.
