How my research helps children

My primary area of interest is health and well being of children. I am currently engaged in research on childhood obesity by examining how child-, family-, and neighbourhood-level predictors affect obesity. I am especially interested in understanding how social and economic disadvantages affect children's obesity and how obesity influences their health at later stages of their life. By understanding the individual and contextual factors that increase children’s risk of obesity, we can develop interventions and public policies that may reduce such risks.


Current Research Activities

Recently, I was awarded a grant to examine the nature of obesity trajectories among children in southwestern Ontario and to assess the impact of various child- and family level determinants of these trajectories. The strength of this study is that it focuses on children living in our region. Hence, the results of this project will inform local researchers and practitioners about how our children compare to those in other regions of the country.

Research Team

My research team consists of one graduate student, Mary Ellen Kuenzig.

Future Research Plans

Collaborating with Dr. Martin Cooke (University of Waterloo), I am developing a research program that will investigate the predictors of obesity among Aboriginal children and then develop a culturally-appropriate framework for the design of a “healthy weights” intervention targeted to Aboriginal children. There will be three components to the study. The first is the use of Statistics Canada survey data to investigate the determinants of obesity, including characteristics of children, families, and neighbourhoods. The second is to use focus groups of parents of off-reserve Aboriginal children to understand their perceptions of the factors that affect their children’s risk of obesity, and to identify appropriate intervention strategies. The third is a series of stakeholder consultation meetings with Aboriginal community organizations, clinicians, and public health practitioners to come to a consensus about a culturally-appropriate framework for an intervention.
