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 .
1% or less: a community-based nutrition campaign.
OBJECTIVE The authors evaluated the effectiveness of a community education campaign to encourage a switch from high-fat ( whole and 2 % ) milk to low-fat ( 1 % , 1/2 % , and skim ) milk as a way to reduce consumption of saturated fat . METHODS Milk sales data were collected from supermarkets in the intervention and comparison communities for three one-month time periods : at baseline , immediately following the campaign , and six months after the campaign . In addition , trained volunteers conducted pre- and post-intervention telephone surveys . RESULTS Overall milk sales increased by 16 % in the intervention cities following the campaign and remained high at follow-up . Low-fat milk 's market share increased from 18 % of overall milk sales at baseline to 41 % of overall milk sales in the month following the end of the campaign , an increase in market share that was sustained at the six-month follow-up . In the post-intervention telephone survey , 38.2 % of those respondents who reported drinking high-fat milk at baseline reported having switched to low-fat milk . CONCLUSION A focused message communicated through paid advertising , public relations activities , and community-based education programs increased low-fat and overall milk consumption in one community
