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 .
Short-term impact of a university based smoke free campaign.
STUDY OBJECTIVE : The aim of this study was to evaluate the impact of a smoke free programme implemented at the University of Geneva , Switzerl and , in 1996 . This programme included a prohibition to smoke in university buildings everywhere except in limited areas , and a smoking cessation counselling service . METHODS : Surveys were conducted before and four months after the programme was implemented , in representative sample s of programme participants ( n = 833 ) and university members not exposed to the programme ( n = 1023 ) . RESULTS : In retrospective assessment s , participants reported being less bothered by environmental tobacco smoke after programme implementation , but no between group difference was detected in prospect i ve assessment s. Relationships between smokers and non-smokers improved moderately in the intervention group and remained unchanged in the comparison group ( between group p = 0.001 ) . Proportions of smokers who attempted to quit smoking in the past four months increased from 2.0 % to 3.8 % in the intervention group and remained unchanged at 3.5 % in the comparison group ( between group difference : p = 0.048 ) . No impact on smoking prevalence ( 25 % ) was detected . The programme was appreciated by university members , although some of its modalities were criticised . CONCLUSION : A regulation prohibiting smoking everywhere but in limited areas of university buildings was acceptable and reduced the perception of bother by environmental tobacco smoke . It did not , however , influence smoking habits or attitudes toward smoking
