Overview

Fiona Bull is affiliated with the World Health Organization in Switzerland and has made significant contributions to research in medicine, particularly focusing on physical activity and health. Their work spans several subfields including physiology, public health, environmental and occupational health, general health professions, transportation, and health. The main topics explored in their research include physical activity and health, obesity related to physical activity and diet, mobile health and mHealth applications, urban transport and accessibility, health disparities and outcomes, behavioral health and interventions, and balance, gait, and falls prevention.

Among the notable recent papers authored or co-authored by Bull are:

  • World Health Organization 2020 guidelines on physical activity and sedentary behaviour (2020), published in the British Journal of Sports Medicine
  • 2020 WHO guidelines on physical activity and sedentary behaviour for children and adolescents aged 5-17 years: summary of the evidence (2020), published in the International Journal of Behavioral Nutrition and Physical Activity
  • National, regional, and global trends in insufficient physical activity among adults from 2000 to 2022: a pooled analysis of 507 population-based surveys with 5.7 million participants (2024), published in The Lancet Global Health
  • Air pollution, physical activity and health: A mapping review of the evidence (2020), published in Environment International
  • The cost of inaction on physical inactivity to public health-care systems: a population-attributable fraction analysis (2022), published in The Lancet Global Health

Fiona Bull has frequently published in a range of academic venues, with the most frequent being:

  • International Journal of Behavioral Nutrition and Physical Activity (7 publications)
  • British Journal of Sports Medicine (5 publications)
  • Journal of Physical Activity and Health (3 publications)
  • Journal of sport and health science/Journal of Sport and Health Science (3 publications)
  • The Lancet Global Health (2 publications)

Their research collaboration network includes frequent co-authorship with several scholars:

  • Juana Willumsen (14 co-authored works)
  • Anne Tiedemann (6 co-authored works)
  • Hidde P. van der Ploeg (6 co-authored works)
  • Stuart Biddle (5 co-authored works)
  • Karen Milton (5 co-authored works)

Within the broad field of medicine, Bull's work has a marked emphasis on physiology and public health issues related to physical activity, sedentary behavior, and their impact on various population groups and health systems. This intersects with concerns about urban transport, accessibility, and the use of mobile technology in health interventions.
