In Japan, the "Food Education Basic Law" (The Basic Law on Shokuiku, food education) was enacted in 2005. The comprehensive food education programs, namely Shokuiku, aim to improve dietary practices to reduce lifestyle-related diseases. Dental caries is one of the diseases associated with inappropriate dietary habits. Thus, food education may influence the prevalence of dental caries. However, there are no data regarding the association between public based-food education and dental caries. The aim of the present study was to investigate the relationship between knowledge about comprehensive food education (Shokuiku) and dental caries experience in Japanese university students. A total of 2,184 students (1,240 men, 944 women), aged 18-20 years, were examined. They had attended the Shokuiku program while in junior/senior high school. The numbers of teeth present, and decayed, missing and filled teeth (DMFT) (dental caries experience) were recorded. Additional information was collected via a questionnaire regarding knowledge about food education, dietary habits and oral health behavior. Of the students, 315 men (20.7%) and 345 women (52.8%) reported that they know and can explain the meaning and content of the word "Shokuiku". After adjusting for potential confounding factors, subjects who did not have knowledge about Shokuiku had higher adjusted odds ratio (OR) for dental caries experience (DMFT >0) than those who had (adjusted OR, 1.23; 95% CI, 1.02-1.48; p<0.05). These observations revealed that having knowledge about comprehensive food education in university students correlates with low prevalence of dental caries.
在日本，《食品教育基本法》（《食育基本法》）于2005年颁布。全面的食品教育项目，即食育，旨在改善饮食习惯以减少与生活方式相关的疾病。龋齿是与不良饮食习惯相关的疾病之一。因此，食品教育可能会影响龋齿的患病率。然而，目前尚无关于基于公众的食品教育与龋齿之间关联的数据。本研究的目的是调查日本大学生对全面食品教育（食育）的了解与龋齿经历之间的关系。共检查了2184名年龄在18 - 20岁的学生（1240名男性，944名女性）。他们在初中/高中时参加过食育项目。记录了现存牙齿数量以及龋、失、补牙数（DMFT）（龋齿经历）。通过问卷调查收集了关于食品教育知识、饮食习惯和口腔健康行为的其他信息。在这些学生中，315名男性（20.7%）和345名女性（52.8%）表示他们知道并能解释“食育”一词的含义和内容。在对潜在混杂因素进行调整后，对食育不了解的受试者患龋齿经历（DMFT >0）的调整后优势比（OR）高于了解食育的受试者（调整后OR，1.23；95%置信区间，1.02 - 1.48；p<0.05）。这些观察结果表明，大学生对全面食品教育的了解与龋齿的低患病率相关。
