The Pennington Generation Cohort is an observational study comprised of Louisiana families. Families will be assessed at baseline for a variety of traits and behaviors, and then followed up over time to try to understand the role of lifestyle and the environment on the risk of developing obesity and other health outcomes.

Pennington Biomedical's Greaux Healthy initiative partners with communities to grow healthier generations by expanding the access and reach of Pennington Biomedical's evidence-based practices for the prevention and treatment of childhood obesity. As part of Greaux Healthy, the Pennington Generation Cohort will help evaluate the impact of the program. A sample of up to 1,500 children and adolescents and their families will be recruited from throughout Louisiana. An initial physical exam will establish a baseline for each family with respect to lifestyle behaviors, genetics, and body size/composition. This longitudinal cohort will also assess the association between participation in several childhood obesity prevention and treatment programs and subsequent obesity and related health outcomes. Members of the longitudinal cohort will be followed in the future through clinical visits, questionnaires, and through optional linkages to electronic medical records and administrative databases such as the National Death Index, Social Security Death Master File, and health registry data.
