| Project Title: | Metabolomics Linking Air Pollution, Obesity and Type 2 Diabetes |
| Project Type: | NIH/NIEHS P01-ES022845 |
| Project Summary: | The overall goal of this proposal is to use blood non-targeted high resolution metabolomics (HRM) to investigate the hypothesis that regional air pollution (NO2, PM2.5 and O3) and traffic-related air pollution exposures (traffic-related particulate matter components including EC2.5 and PM2.5 transition metals, and CALINE model-predicted NOx) alter key metabolic pathway(s) and that these alterations are associated with obesity and type 2 diabetes-related traits during the important developmental period of adolesence in the ongoing prospective Chidlren's Health study (CHS). Specific Aim 1 will examine the adverse impact of environmental chemicals in fasting blood samples measured by HRM on obesity (i.e., total body fat and body mass index (BMI)), metabolic dysfunction (e.g., fasting glucose and insulin concentrations and insulin resistance), and obesity-induced inflammation (i.e., leptin) among 104 Southern California adolescents enrolled in the CHS. Specific Aim 2 will examine associations of childhood exposures to PM2.5 and traffic-related air pollutants (i.e., CALINE model-predicted NOx) with biological metabolites identified in fasting blood samples using HRM among 104 adolescents in the CHS. Specific Aim 3 will investigate the metabolic pathways linking air pollution exposures and obesity and type 2 diabetes-related traits using pathway analysis under bayesian hierarchical model among 104 adolescents in the CHS. |
