People’s physical activity (PA) throughout an entire day is a key determinant of health. Health is not only influenced by PA of moderate-to-vigorous intensity (MVPA), but also by lighter intensity, as well as daily doses of sitting and standing. Thus, PA (and its absence) in any domain of the day should not be ignored in the investigation and promotion of health. We therefore think it is unfortunate that two complementary research disciplines—public health and occupational health—have essentially been incommunicado divorcees for the past 60 years.
PA research in public and occupational health started united during the 1950s—recall the studies of work-related PA by Morris (London bus drivers)1 and Paffenbarger (San Francisco longshoremen).2 Today, however, the two fields rarely engage in meaningful collaboration. Work-related PA was barely mentioned in the US 2018 Physical Activity Guidelines Advisory Committee Scientific Report,3 as ‘Most of the research findings summarized for this report are based on studies of leisure time PA’.3
In this editorial, we answer the question ‘Where did it all go wrong?’ and recommend ways for ‘remarrying’ the disciplines in order to develop coherent advice for adults from all walks of life.
Where did it all go wrong?
There are three reasons for the diverged directions of public and occupational health. First, the two disciplines operate in silos, and understand and interpret PA differently; this leads to different PA health advice for people …
