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 .
A controlled trial of a school-based environmental intervention to improve physical activity in Dutch children: JUMP-in, kids in motion.
Interventions to promote physical activity are important in preventing children from becoming overweight . Many projects have been developed but only a few showed ( moderate ) effects . JUMP-in is a systematic ally developed primary -school-based intervention that focuses on the use of theory , environmental changes , parental influences and cooperation with multi-level parties in intervention development . The effects of JUMP-in were evaluated with a quasi-experimental pre-test/post-test research design . In total , 510 children from Grade s 4 , 5 and 6 of four intervention schools and two control schools in Amsterdam were followed for an intervention period of one school year . Changes in physical activity as well as in the social cognitive determinants were assessed using self-reports . In addition , a process evaluation has been executed . The results show that JUMP-in was effective in influencing physical activity , especially among children from Grade 6 . Children in the control group decreased their level of physical activity considerably , while activity levels in intervention children from Grade 6 remained stable . The intervention effects could not be explained by changes in the measured social cognitive determinants . In contrast , process information illuminated differences in intervention effects between the participating schools . The results from the JUMP-in study show the importance of intervention design s that focus on a theory-based mix of relevant environmental and social cognitive factors
