The aim of this study was to examine the trend of average frequency of toothbrushing per day according to the sociodemographic characteristics using the 5th, 6th, and 7th Korean National Health and Nutrition Examination Survey (KNHANES) data for 9 years; from 2010 to 2018. It intends to understand the state of toothbrushing practices in South Korea, and to provide basic data for promoting toothbrushing practices. Data from the 5th, 6th, and 7th KNHANESs conducted by the Korean Disease Control and Prevention Agency each year was analyzed using IBM SPSS version 26.0 (IBM Co., Armonk, NY, USA). Tableau version 2020.1 was used for the graphs and geographic information system (GIS). The significance level of α was set at 0.05 for testing. In all analyses, the complex sampling analysis method with stratification variables, cluster variables, and weights was applied, and the complex sample linear regression analysis. The average frequency of toothbrushing per day was higher in women for all the years; these women belonged to the age group under 65 and the employed group. The average frequency of toothbrushing per day was lower in the married, elementary school graduate, part-time job, and low-income groups for all years. The demographic and social factors affecting the number of toothbrushing practices per day were gender, education level, income level, and work type. After analyzing the average frequency of toothbrushing per day in each of the cities and provinces, Gangwon-do and Jeonbuk showed the highest increase in the frequency of toothbrushing in 2018 compared to 2010, whereas Incheon showed the lowest increase. From the above results, the average frequency of toothbrushing per day was lower in males, those with a low education level, the unemployed, and those in the rural area for a period of 9 years. Therefore, in-depth oral health promotion projects and national benefit policies should be considered for effective toothbrushing education by identifying individuals who do not brush their teeth.
本研究旨在利用韩国疾病控制与预防署（Korean Disease Control and Prevention Agency）于 2010 年至 2018 年进行的第 5、6 和 7 次韩国国民健康与营养调查（Korean National Health and Nutrition Examination Survey，KNHANES）数据，分析 9 年来每日平均刷牙频率随社会人口学特征的变化趋势。本研究旨在了解韩国的刷牙现状，为推广刷牙行为提供基础数据。本研究使用 IBM SPSS 版本 26.0（IBM Co.，Armonk，NY，USA）对第 5、6 和 7 次 KNHANES 的数据进行分析。Graph 和地理信息系统（GIS）使用 Tableau 版本 2020.1。采用具有分层变量、聚类变量和权重的复杂抽样分析方法进行统计分析，并进行复杂样本线性回归分析。所有年份中，女性每日平均刷牙频率均高于男性；这些女性属于 65 岁以下和就业人群。所有年份中，已婚、小学及以下学历、兼职和低收入群体的每日平均刷牙频率均较低。影响每日刷牙次数的人口统计学和社会因素包括性别、教育水平、收入水平和工作类型。在分析每个城市和省份的每日平均刷牙次数后发现，2018 年与 2010 年相比，江原道和全罗北道的刷牙频率增幅最高，而仁川市的增幅最低。从以上结果可以看出，9 年来，男性、受教育程度低、失业者和农村地区的人每日平均刷牙频率较低。因此，应考虑开展深入的口腔健康促进项目和国家福利政策，通过识别不刷牙的个体，开展有效的刷牙教育。
