目的：这项研究评估了位于南奥克兰社会经济贫困地区的Yendarra小学实施的健康食品政策是否改善了学生的口腔健康，方法是将相同地区类似学校的学生的龋齿水平与没有实施此类政策的学生进行比较。方法：获得2007至2014年间Yendarra学校儿童的乳牙和成人牙齿龋齿记录，并将其与该地区其他8所人口统计数据相似的公立学校的记录进行比较。年龄在8岁到11岁之间的儿童被选中。结果：在研究期间，共获得3813份参加牙科检查的儿童和感兴趣的学校的记录。在线性模型中，在调整混杂因素后，Yendarra学龄儿童的乳牙和成人龋齿的平均数量比其他学校的儿童低0.37颗(95%可信区间：0.09-0.65)。太平洋地区学生的龋齿数量(调整后的β系数：0.25；95%可信区间：0.03-0.46)高于毛利族学生。结论：南奥克兰最贫困地区的一所学校实施的这项限制含糖食物和饮料供应的营养政策，与周围学校的学生相比，对学生的口腔健康有显著的积极影响。我们建议这些政策是改善儿童口腔健康的有用手段。
Aim: The study assessed whether a healthy food policy implemented in one school, Yendarra Primary, situated in a socio-economically deprived area of South Auckland, had improved student oral health by comparing dental caries levels with students of similar schools in the same region with no such policy.Methods: Records of caries of the primary and adult teeth were obtained between 2007 and 2014 for children attending Yendarra, and were compared to those of eight other public schools in the area, with a similar demographic profile. Children were selected between the ages of 8 and 11 years. Linear regression models were used to estimate the strength of association between attending Yendarra school and dental caries.Results: During the study period, 3813 records were obtained of children who attended dental examinations and the schools of interest. In a linear model, mean number of carious primary and adult teeth were 0.37 lower (95% confidence interval: 0.09-0.65) in Yendarra school children, compared to those in other schools, after adjustment for confounders. Pacific students had higher numbers of carious teeth (adjusted beta coefficient: 0.25; 95% confidence interval: 0.03-0.46) than Maori.Conclusion: This nutrition policy, implemented in a school in the poorest region of South Auckland, which restricted sugary food and drink availability, was associated with a marked positive effect on the oral health of students, compared to students in surrounding schools. We recommend that such policies are a useful means of improving child oral health.
