The prevalence and seriousness of childhood obesity has prompted calls for broad public health solutions that reach beyond clinic settings. Schools are ideal settings for population-based interventions to address obesity.<\/jats:p>\n               <jats:p>OBJECTIVE. The purpose of this work was to examine the effects of a multicomponent, School Nutrition Policy Initiative on the prevention of overweight (85.0th to 94.9th percentile) and obesity (&amp;gt;95.0th percentile) among children in grades 4 through 6 over a 2-year period.<\/jats:p>\n               <jats:p>METHODS. Participants were 1349 students in grades 4 through 6 from 10 schools in a US city in the Mid-Atlantic region with \u226550% of students eligible for free or reduced-price meals. Schools were matched on school size and type of food service and randomly assigned to intervention or control. Students were assessed at baseline and again after 2 years. The School Nutrition Policy Initiative included the following components: school self-assessment, nutrition education, nutrition policy, social marketing, and parent outreach.<\/jats:p>\n               <jats:p>RESULTS. The incidences of overweight and obesity after 2 years were primary outcomes. The prevalence and remission of overweight and obesity, BMI z score, total energy and fat intake, fruit and vegetable consumption, body dissatisfaction, and hours of activity and inactivity were secondary outcomes. The intervention resulted in a 50% reduction in the incidence of overweight. Significantly fewer children in the intervention schools (7.5%) than in the control schools (14.9%) became overweight after 2 years. The prevalence of overweight was lower in the intervention schools. No differences were observed in the incidence or prevalence of obesity or in the remission of overweight or obesity at 2 years.<\/jats:p>\n               <jats:p>CONCLUSION. A multicomponent school-based intervention can be effective in preventing the development of overweight among children in grades 4 through 6 in urban public schools with a high proportion of children eligible for free and reduced-priced school meals.<\/jats:p>","DOI":"10.1542\/peds.2007-1365","type":"journal-article","created":{"date-parts":[[2008,4,1]],"date-time":"2008-04-01T20:25:58Z","timestamp":1207081558000},"page":"e794-e802","source":"Crossref","is-referenced-by-count":331,"title":["A Policy-Based School Intervention to Prevent Overweight and Obesity"],"prefix":"10.1542","volume":"121","author":[{"given":"Gary D.","family":"Foster","sequence":"first","affiliation":[{"name":"Center for Obesity Research and Education, Temple University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandy","family":"Sherman","sequence":"additional","affiliation":[{"name":"The Food Trust, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelley E.","family":"Borradaile","sequence":"additional","affiliation":[{"name":"Center for Obesity Research and Education, Temple University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen M.","family":"Grundy","sequence":"additional","affiliation":[{"name":"Department of Clinical Developmental Psychology, Bryn Mawr College, Bryn Mawr, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie S.","family":"Vander Veur","sequence":"additional","affiliation":[{"name":"Center for Obesity Research and Education, Temple University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joan","family":"Nachmani","sequence":"additional","affiliation":[{"name":"Department of Health, Physical Education, Safety and Sports Administration, School District of Philadelphia, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allison","family":"Karpyn","sequence":"additional","affiliation":[{"name":"The Food Trust, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiriki","family":"Kumanyika","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Epidemiology, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justine","family":"Shults","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Epidemiology, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2008,4,1]]},"reference":[{"key":"2021120902122040600_R1","doi-asserted-by":"crossref","unstructured":"Koplan JP, Liverman CT, Kraak VI, eds.
