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 .
Effects of socialization in the household on youth susceptibility to smoking: a secondary analysis of the 2004/05 Canadian Youth Smoking Survey.
OBJECTIVE To determine associations between younger youths ' susceptibility to smoking and four household variables related to tobacco socialization : parental and sibling smoking , restrictions on smoking in the home and exposure to smoking in vehicles . METHODS A secondary analysis of the 2004/05 Canadian Youth Smoking Survey used logistic regression to investigate the relationships between youth susceptibility to smoking , gender , and four household variables related to tobacco socialization . Susceptibility to smoking was operationalized by three levels of smoking experience and intention : non-susceptible non-smoker , susceptible non-smoker and experimenter/smoker . The national survey included 29 243 grade 5 to 9 students from r and omly sample d public and private schools in ten provinces . RESULTS For non-smokers , the odds of being susceptible to smoking increased with having a sibling who smokes , a lack of a total household smoking ban and riding in a vehicle with a smoker in the previous week , when adjusting for all other variables in the model . These variables also increased the odds of being an experimenter/smoker versus a susceptible non-smoker . Parent smoking status  was not significant in these models . CONCLUSION Denormalization messages , through enforced home and vehicle smoking bans , appear to support youth in maintaining a resolve to not smoke , regardless of parental smoking status
