Overview

Tamara Cohen, PhD, RD is an Assistant Professor and the Director of Dietetics in the Faculty of Land and Food Systems at UBC. Her laboratory at the UBC Vancouver Campus. Her research program focuses on eating behaviours throughout the lifespan, with the goals of improving dietary habits. To do so, her team bases their research on theoretical frameworks and applies them to the nutrition / dietary context. Her team is also involved in creating nutrition education tools and resources with the goals of educating people about healthy eating and then assessing the tool’s impact on changing diet. In addition, Dr. Cohen supports research out of BC Children’s Hospital Shapedown program, a program intended for families of children living with obesity and Montreal Children’s Hospital Adolescent Medicine Unit, supporting adolescents living with severe obesity who are undergoing bariatric surgery.

Dr. Cohen's research program addresses the following objectives:

-To improve adherence to lifestyle interventions, specifically targeting diet and eating behaviours for individuals (children, adolescents and adults) living with overweight or obesity.

-To develop novel education and dietary assessment tools to improve diet quality throughout the lifespan.

Research

Working with BC Children’s Hospital Shapedown Program: A 10-week holistic approach to weight management issues for children, adolescents, and their families
Together with Dr. Eli Puterman, our projects are centered around program evaluation which include exploring changes in participant’s health behaviours.

Development of a dietary self-monitoring tool that aligns with Canada’s Food Guide
Adherence to changes in diet in the long run are very hard. Self-monitoring, or tracking what you eat, is one method often used to help people eat according to guidelines. This study aims to create a mobile application that mirrors Canada’s Food Guide as a way to help people eat balanced diets.

“Protein Cards”: A nutrition education resource to support post-operative nutrition for adolescents living with severe obesity who have undergone bariatric surgery
Bariatric surgery for adolescents living with severe obesity is emerging as a treatment option to help manage obesity in Canada. Working with the Center for Excellence for Adolescents Living with Severe Obesity (CEASO) Unit at Montreal Children’s Hospital (Montreal, QC), this project aims to create a nutrition education tool for adolescents to help manage adherence to what is often a drastically new way of eating after surgery and beyond.
