Bronwyn Clark is an epidemiologist specialising in the field of measurement of physical activity and sedentary behaviour. She is currently working as a Senior Research Fellow at the School of Human Movement and Nutrition Sciences, The University of Queensland and holds a National Health and Medical Research Council of Australia Fellowship. Dr Clark is an internationally recognised expert in the measurement of physical behaviour using both self-report and objective methods including newer combined methods such triggered ecological momentary assessment. She has a particular interest in workplace health behaviour but also works with clinical and broader adult populations. Dr Clark has the honour of being the current president of International Society for the Measurement of Physical Behaviour.

Research Impacts

Dr Clark's research into measuring sedentary behaviour has had broad national and international impact. Measures she developed on domain specific sitting were included for the first time in the 2011/12 Australian Diabetes, Obesity, and Lifestyle study (administered to 6182 people) and influenced the inclusion of domain specific questions in the 2010/11 Australian Health Survey (administered to 9,500 private dwellings). Her questionnaires have been used in other countries (Chile, Japan, USA, Malaysia). Additional ground-breaking innovations include developing measures of how sitting time is accumulated and in using technological advances to identify context of behaviour which have been taken up in workplace programs through the BeUpstanding program, which has been taken up by over 800 organisations across Australia.

Dr Clark’s international leadership in the field of behaviour measurement resulted in her election as President of the International Society for the Measurement of Physical Behaviour. She regularly delivers industry talks and has been asked to provide input into governmental strategy at the Healthy Queenslanders - Health and Wellbeing through physical activity consultation with Queensland Department of Housing and Public Works. Her work is cited outside academia with five of publications referenced in policy documents.
