这项研究的目的是评估加拿大新斯科舍省实施省级学校营养政策前后儿童膳食摄入量和体重状况的人口水平趋势。2003年(n=15215)和2011年(5508)，即政策实施前后，作为人口层面研究的一部分，收集了自我报告的饮食行为和营养素摄入量以及测量的体重指数。我们使用随机效应回归方法来评估该政策对饮食和健康结果的影响。2011年，学生报告消费了更多的奶制品，而调整后的模型中蔬菜和水果的平均消费量没有差异。调整后的回归分析显示，含糖饮料的消费量在统计上有显著下降。尽管饮食能量摄入量在短期内显著减少，饮食质量有所提高，但超重和肥胖的患病率继续上升。这项人群层面的干预研究表明，学校营养政策对饮食质量、能量摄入和健康饮料消费产生了积极影响，需要采取更多学校以外的行动来遏制儿童肥胖率的上升。研究为学校营养政策(SNP)的作用提供了“真实世界”的证据。SNP的实施导致了含糖饮料(SSB)的摄入量减少。SNP的实施改善了膳食摄入量，减少了样本中的能量。
The objective of this study is to assess population-level trends in children's dietary intake and weight status before and after the implementation of a provincial school nutrition policy in the province of Nova Scotia, Canada. Self-reported dietary behavior and nutrient intake and measured body mass index were collected as part of a population-level study with grade 5 students in 2003 (n = 5215) and 2011 (5508), prior to and following implementation of the policy. We applied random effects regression methods to assess the effect of the policy on dietary and health outcomes. In 2011, students reported consuming more milk products, while there was no difference in mean consumption of vegetables and fruits in adjusted models. Adjusted regression analysis revealed a statistically significant decrease in sugar-sweetened beverage consumption. Despite significant temporal decreases in dietary energy intake and increases in diet quality, prevalence rates of overweight and obesity continued to increase. This population-level intervention research suggests a positive influence of school nutrition policies on diet quality, energy intake and healthy beverage consumption, and that more action beyond schools is needed to curb the increases in the prevalence of childhood obesity. Study provides “real world” evidence on the role of school nutrition policies (SNP). SNP implementation led to decreased intake of sugar-sweetened beverages (SSB). SNP implementation led to improved dietary intake and reduction in energy in sample.
