Several specific population interventions that achieved a Class I or IIa recommendation with grade A or B evidence were identified , providing a set of specific evidence -based strategies that deserve close attention and prioritization for wider implementation .
Effective interventions included specific approaches in all 6 domains evaluated for improving diet , increasing activity , and reducing tobacco use .
The writing group also identified several specific interventions in each of these domains for which current evidence was less robust , as well as other inconsistencies and evidence gaps , informing the need for further rigorous and interdisciplinary approaches to evaluate population programs and policies .
This systematic review identified and grade d the evidence for a range of population -based strategies to promote lifestyle change .
BACKGROUND Poor lifestyle behaviors , including suboptimal diet , physical inactivity , and tobacco use , are leading causes of preventable diseases globally .
Although even modest population shifts in risk substantially alter health outcomes , the optimal population -level approaches to improve lifestyle are not well established .
Promoting healthy eating and physical activity short-term effects of a mass media campaign.
BACKGROUND Soaring obesity levels present a severe health risk in the United States , especially in low-income minority population s. INTERVENTION High-frequency paid television and radio advertising , as well as bus and streetcar signage . SETTING / PARTICIPANTS A mass media campaign in New Orleans to promote walking and fruit and vegetable consumption in a low-income , predominantly African-American urban population . Messages tailored with consideration of the African-American majority . DESIGN R and om-digit-dial telephone surveys using cross-sectional representative sample s at baseline in 2004 and following the onset of the campaign in 2005 . MEASURES Survey items on campaign message recall ; attitudes toward walking , snack food avoidance , and fruit and vegetable consumption ; and behaviors related to fruit and vegetable consumption , snack food consumption , and utilitarian and leisure walking . RESULTS From baseline , there were significant increases in message recall measures , positive attitudes toward fruit and vegetable consumption , and positive attitudes toward walking . Behaviors did not change significantly . In 2005 , message recall measures were associated with positive levels of each of the outcome variables . CONCLUSIONS Over 5 months , the media campaign appeared to have stimulated improvements in attitudes toward healthy diet and walking behaviors addressed by the campaign . These findings encourage the continuation of the media campaign , with future evaluation to consider whether the behavioral measures change
