However, the success of these PAs is largely restricted by ecological gaps in PA structure, defects of the management system, and is also negatively influenced by local development and urbanization driven by a growing economy.
Offering the telephone counselling calls when the patient is at home again, is in line with the ecological models of PA that suggest that behavioural settings and the broader social context also influence uptake and maintenance of PA behaviour.
This hypothesis relies on the assumption that breast cancer survivors are a somewhat heterogeneous group in terms of determinants (i.e., demographics, social-cognitive and ecological factors) of PA behaviour change.
The intervention components across all three phases of testing represent a socio-ecological approach to PA promotion in adults, with some small adaptations throughout the phases [ 18].
The project components, representing nine socio-ecological components for PA promotion, reflect the key intervention strategies applied in the pilot study in the city of Ghent and the dissemination and implementation study of '10,000 Steps' in the Flanders region [ 15, 19].
PA performed ecological niche models.
As a first step, we propose the designation of a "zone of interaction" (ZOI) around PAs that encompasses hydrologic, ecological, and socioeconomic interactions between a PA and the surrounding landscape.
The current study builds on a comprehensive socio-ecological model positing that PA behavior results from multiple influences [ 19].
Environmental influences on PA, founded in ecological and social cognitive perspectives, have not been examined among children living in colonias.
While earlier research on this topic focused mainly on the contribution of personal determinants of PA behavior, social ecological models have been of growing interest during the last decade.
