Study Overview
Brief Summary
This study aims to assess the effects of environmental pollution (including environmental indicators such as PM2.5, PM5, PM10, SO2, NOX, O3, and greening index) on obese patients and to explore the possible mechanisms by which environmental pollution promotes obesity.
Detailed Description
Firstly, the effects of environmental pollution on obese patients were investigated by analysing the baseline conditions and obesity levels (including BMI, waist circumference, hip circumference, etc.) and underlying diseases of obese patients in regions with different pollution levels. Secondly, the association between environmental pollution levels on blood test characteristics (including renal function, sex hormones, glucose tolerance test, trace elements, liver function and blood routine) of obese patients was investigated to find possible mechanisms.
