Simply offering attractive large parks may be insufficient to increase already low community-wide physical activity levels.
Although regular physical activity is thought to underpin the favorable metabolic profiles of the MHO phenotype, to our knowledge the impact of a community-wide physical activity intervention to transition individuals from MAO to MHO has not been scientifically explored.
In the dissemination and implementation literature, there is a dearth of information on the sustainability of community-wide physical activity (PA) programs in general and of the '10,000 Steps' project in particular.
Strengths of this study include its contribution to a small available literature on the sustainability of community-wide physical activity (PA) programs in general and of '10,000 Steps' in particular.
The wide variability in physical activity classification was explained by ostensibly subtle differences between the 12 recommendations for thresholds related to activity volume (time or energy), distribution (e.g., number of days of the week), moderate intensity cut-point (e.g., 3 vs. 4 metabolic equivalents or METs), and duration (including bout length).
There was a wide variation in physical activity class (occupational, commuting, and leisure-time physical activities) with the highest MET.
This wide variation of physical activity prevalence may be due to different socio-demographic characteristics and lifestyle among the groups studied, as well as differences in the definition of physical inactivity and the tools used to measure physical activity.
To our knowledge, this is the largest study so far investigating the association between a wide range of physical activity and mammographic density in women, and also the first to use volumetric density as the outcome.
For example, the Canadian study assessed a wide variety of physical activity settings (recreational, household, occupational) and categorized results by setting type, whereas some other studies focused only on recreational or leisure-time activity and categorized results by intensity (mild, moderate, vigorous, total).
HEPA policies are embedded within a wider socio-economic context, and HEPA policies should therefore target wider determinants of physical activity and its impact on health.
