Tracie Barnett

Épidémiologie de l'obésité pédiatrique

Dr. Barnett is an Associate Professor and an FRQS Senior Career Award Scholar. She has a laboratory at the CHU Sainte-Justine Children's Hospital Research Centre with affiliations in Family Medecine at McGill University and the School of Public Health at Université de Montréal. The overarching aim of Dr. Barnett's program of research focuses on investigating the influence of features of built and social environments on pediatric obesity, and how these can be leveraged to promote healthy weight. She oversees a state of the art spatial-environmental diagnostic and analytic laboratory that consolidates environmental with clinical date and wich supports a range of original methodological, etiological, and applied research endeavours. Her research focuses on defining relevant environments, capturing salient characteristics and producing meaningful indicators within residential neighborhoods, schools and social networks; exploring how these change and evolve over time as youth grow and mature; and testing their potential influence on cardiovascular risk factors including obesity and related lifestyle behaviours. Projects also measure novel risk factors and test innovative hypotheses underlying potential mediating pathways in the environment-obesity relation. She strives to translate methodological and etiological findings to clinical apllications and public health extensions. Ultimately, she seeks to identify targets that could reduce the obesogenic nature of environments.
