The Ecological Model

1. What are the basic principles of the ecological model in health promotion and public health?

There are four basic principles of the ecological model in health promotion and public health:
(a) theoretical propositions for the interrelationships between persons and settings: The base of the theory is that the way in which goals are structured determines how individuals interact, which in turn creates outcomes.
(b)constructionist premises, the social construction of ecological knowledge - This component recognizes the social construction of ecological knowledge. The social environment comprises the relationships, the culture and the society with whom the individual interacts.
(c) collaborative style: These components relate to how researchers and participants can

In the context of physical activity, ecological models have provided a framework to various institution. For example, American, European, and Canadian frameworks, policy statements, and action plans have adhered to the notion that the enhancement of population health demands action that focuses simultaneously on the personal and on the environmental determinants of health: The United States Physical Activity Plan, 2010(http://www.physicalactivityplan.org/); The Integrated Pan-Canadian Active Living Strategy (69); Healthy People 2010 (83); The WHO Global Strategy on Diet, and Physical Activity and Health.
To help us understand a specific problem in a setting or context. For instance, at least three groups of authors have proposed that scholars apply the ecological approach to understand and promote physical activity.
Models are used to inform intervention development, implementation and evaluation.
For example, planning models such as the PRECEDE-PROCEED model and Intervention Mapping explicitly integrate concepts emerging from an ecological perspective into their conceptual
