This ecologic study compared school-level oral health outcomes in schools participating in Ontario's "Healthy Schools" program and nonparticipating schools in York Region, Ontario in 2007-2008 and examined the effect of neighbourhood socio-economic factors.
School-aggregated data were obtained for all 243 elementary schools. York Region Public Health Unit provided oral health data from school dental screenings. We obtained information about schools participating in the Ontario's "Healthy Schools" program from publicly accessible websites. Neighbourhood socio-economic data based on school postcodes were extracted from Statistics Canada (2006) census databases. School oral health outcomes included the percentage of children in each school requiring preventive care, non-urgent dental treatment, urgent dental treatment and children with > or = two decayed teeth.
One hundred and six elementary schools (42%) participated in Ontario's "Healthy Schools" program in 2007-2008. Schools participating in the "Healthy Schools" program had a significantly lower percentage of children with > or = two decayed teeth (p < 0.001) and children requiring urgent dental treatment (p = 0.004) than non-participating schools. School participation/neighbourhood socio-economic factors interactions showed that a significantly lower percentage of children in low-income "Healthy Schools" had preventive and urgent dental treatment needs and > or = two decayed teeth than in low-income non-participating schools (p < 0.001).
Schools participating in Ontario's "Healthy Schools" program had better school oral health outcomes than non-participating schools. School neighbourhood socio-economic factors affected school oral health outcomes, which could suggest that schools situated in poorer neighbourhoods may benefit more from health promotion activities than schools situated in more affluent neighbourhoods.
本生态研究比较了 2007-2008 年安大略省“健康学校”计划参与学校和安大略省约克区非参与学校的学校口腔健康结果，并考察了邻里社会经济因素的影响。
获取了所有 243 所小学的学校汇总数据。约克区公共卫生局提供了学校牙科筛查的口腔健康数据。我们从公开网站获取了有关安大略省“健康学校”计划参与学校的信息。基于学校邮政编码的邻里社会经济数据从加拿大统计局（2006 年）人口普查数据库中提取。学校口腔健康结果包括每所学校需要预防保健、非紧急牙科治疗、紧急牙科治疗以及有≥2 颗龋齿的儿童的百分比。
2007-2008 年，有 106 所小学（42%）参与了安大略省的“健康学校”计划。参与“健康学校”计划的学校有≥2 颗龋齿的儿童比例（p<0.001）和需要紧急牙科治疗的儿童比例（p=0.004）明显低于非参与学校。学校参与/邻里社会经济因素的相互作用表明，低收入“健康学校”中需要预防和紧急牙科治疗以及≥2 颗龋齿的儿童比例明显低于低收入非参与学校（p<0.001）。
参与安大略省“健康学校”计划的学校的学校口腔健康结果优于非参与学校。学校邻里社会经济因素影响学校口腔健康结果，这表明位于较贫困社区的学校可能比位于较富裕社区的学校从健康促进活动中获益更多。
