Background: In July, 2019, the World Health Organization (WHO) commenced work to update the 2010 Global
Recommendations on Physical Activity for Health and established a Guideline Development Group (GDG)
comprising expert public health scientists and practitioners to inform the drafting of the 2020 Guidelines on
Physical Activity and Sedentary Behavior. The overall task of the GDG was to review the scientific evidence and
provide expert advice to the WHO on the amount of physical activity and sedentary behavior associated with
optimal health in children and adolescents, adults, older adults (> 64 years), and also specifically in pregnant and
postpartum women and people living with chronic conditions or disabilities.
Methods: The GDG reviewed the available evidence specific to each sub-population using systematic protocols
and in doing so, identified a number of gaps in the existing literature. These proposed research gaps were
discussed and verified by expert consensus among the entire GDG.Results: Evidence gaps across population sub-groups included a lack of information on: 1) the precise shape of the
dose-response curve between physical activity and/or sedentary behavior and several of the health outcomes
studied; 2) the health benefits of light-intensity physical activity and of breaking up sedentary time with lightintensity
activity; 3) differences in the health effects of different types and domains of physical activity (leisure-time;
occupational; transportation; household; education) and of sedentary behavior (occupational; screen time; television
viewing); and 4) the joint association between physical activity and sedentary time with health outcomes across the
life course. In addition, we acknowledge the need to conduct more population-based studies in low- and middleincome
countries and in people living with disabilities and/or chronic disease, and to identify how various
sociodemographic factors (age, sex, race/ethnicity, socioeconomic status) modify the health effects of physical
activity, in order to address global health disparities.
Conclusions: Although the 2020 WHO Guidelines for Physical Activity and Sedentary Behavior were informed by
the most up-to-date research on the health effects of physical activity and sedentary time, there is still substantial
work to be done in advancing the global physical activity agenda.
