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.
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.
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 β coefficient: 0.25; 95% confidence interval: 0.03-0.46) than Māori.
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.
本研究通过比较位于南奥克兰社会经济贫困地区的延达拉小学实施健康食品政策后学生的龋齿水平与该地区其他未实施此类政策的类似学校的学生，评估该政策是否改善了学生的口腔健康。
获取了2007年至2014年间延达拉小学儿童的乳牙和恒牙龋齿记录，并与该地区其他八所人口统计学特征相似的公立学校的记录进行比较。选取年龄在8至11岁之间的儿童。使用线性回归模型估计就读于延达拉学校与龋齿之间的关联强度。
在研究期间，获得了3813份参加牙科检查的儿童和相关学校的记录。在一个线性模型中，在对混杂因素进行调整后，延达拉学校儿童的乳牙和恒牙龋齿平均数量比其他学校的儿童低0.37（95%置信区间：0.09 - 0.65）。太平洋岛裔学生的龋齿数量（调整后的β系数：0.25；95%置信区间：0.03 - 0.46）高于毛利学生。
在南奥克兰最贫困地区的一所学校实施的这项限制含糖食品和饮料供应的营养政策，与周边学校的学生相比，对学生的口腔健康产生了显著的积极影响。我们建议此类政策是改善儿童口腔健康的有效手段。
