Adherence
Environmental factors (physical, social, and policy) significantly influence nutrition and physical activity behaviors, but their impact is often weaker than or interacts with individual-level determinants such as motivation and self-efficacy.
To improve nutrition and physical activity, focus on modifying the environment (e.g., access to parks, healthy food availability, safety) alongside individual education. Recognize that environmental changes can support those with lower self-efficacy, but personal factors remain strong predictors of behavior.
Two recent exceptions in the physical activity literature reported quite similar patterns of findings – that selected personal, social, and physical environmental factors were all associated with leisure-time walking [47] and with exercising as recommended [56], with personal influences showing the strongest associations.
Why this rating
The paper is a commentary/review highlighting methodological challenges and patchy evidence, not a primary clinical trial.
