    Summary

    My research integrates both population-based strategies (environmental and policies strategies) and behavioural strategies (individual-based psychological strategies) to address the complexity of influences on health behaviours associated with obesity (Physical Activity (PA), sedentary, and dietary behaviours).

    My population-based research, investigates the hierarchies of factors influencing children’s behaviours at school and childcare settings. This work uses a systems perspective to understand influences on nutrition and PA environments and how they are linked with children health behaviours and weight outcomes.

    My behavioural research takes a socio-ecological perspective to examine various aspects of the environment that influence children’s behaviours associated with obesity. This research provides the foundational work to improve the efficacy of lifestyle interventions, and points to the need to understand influences of the familial environment from a holistic perspective and to focus on transitional periods in adolescence.

    Current Projects

    A Good Start Matters - Creating environments that support physical activity in childcare setting 
    Funded by SSHRC ($145,000 2017/19) and CHIR ($734,400 2017-22), these studies aim to: 1) evaluate how provincial standards supported by a capacity building intervention influence childcare centre practices; and 2) whether childcare centre that have better environments, policies, and practices enhance children physical activity and motor skill competencies.


    Impact of transitioning to secondary schools on behaviours associated with obesity and academic-related outcomes: A socio-ecological perspective
    Lack of physical activity, too much sedentary time, and poor dietary habits all contribute to unhealthy weight trajectories. Adolescence is a period when many unhealthy behaviours emerge or escalate; most notably these problems are exacerbated during the transition from elementary to secondary school. This study funded by CIHR ($909,155 2015/2022) aim to examine factors that influence adolescents’ physical activity, sedentary time, and dietary habits as children transition from elementary to secondary school. Using qualitative and quantitative methods, this study examines changes that occur in the school, household, and social settings among 736 student/parent pairs from 49 schools in BC.

    Development and evaluation of LiGHT version 2, a novel weight management program for 10 to 17 year-old and their families 
    This is a collaborative agreement with the Childhood Obesity Foundation (COF) that is funded but PHAC with matched funding from Ayogo Health Inc., Merk Canada and Heart and Stroke. In addition, the David Suzuki provide in-kind content to support the living green focus of LiGHT. The LiGHT (Living Green and Healthy for Teens) program aim to engage youth and their families with interactive and gamified content to modify adolescents and their families’ health behaviours associated with obesity (Physical activity, sedentary, nutrition, and sleep behaviours). BCCHR/UBC investigators lead the evaluation of this study which includes 6 collaborative centres (Alberta Children’s Hospital U of Calgary, Children’s Hospital of Eastern Ontario U of Ottawa, McMaster Children’s Hospital U of McMaster, Shapedown BC BC Children’s Hospital UBC, SickKids U of Toronto, Stollery Children’s Hospital U of Edmonton): the cooperative agreement with COF ($732,211 2017/21) is to conduct a randomized control trial to test the efficacy of the LiGHT intervention; 2) CIHR and Alberta Innovate funds ($388,375 2018/2021) are used to examine factors at the individual, social and environmental levels that influence adherence to the LiGHT intervention.

    Improving measures of nutrition and physical activity parenting
    Although parenting practices are widely recognized as an important target for family-based intervention, our ability to understand the influence of the family is hampered by our ability to measure parenting practices. Researchers have developed different ways to measure parenting practices related to physical activity and nutrition; however no agreement has been reached in the scientific community. Funded by CIHR ($573,156 2012/16) this study engages the international scientific community in developing a common conceptual framework for assessing parenting practices related to physical activity and nutrition.  This information served to develop an item bank that is currently being calibrated with advanced psychometric methods. Findings from this study provide the groundwork for future research aimed at understanding the influence of parenting practices.
