To study the impact of lifestyle factors on dental caries experiences in addition to the effect of demographic characteristics at the ages of 9, 15, and 21 years.
The data were obtained from the study 'Oral health in children and adolescents in the Netherlands'. Data were collected through questionnaires and a clinical oral examination. Because the DMFS count data were highly skewed with a peak at zero, the negative binomial hurdle model was used for the analyses. The first part of the hurdle predicted the probability of having caries experience or not, and the second part predicted the degree of caries experience.
For the 9- and 15-year-old age groups, the breakfast frequency per week was related with having caries experience, while the frequency of brushing teeth per day was related with the degree of caries experience. In addition, the number of food and drinks consumed per day was important for the younger age group. These relations were not found in the 21-year-olds age group.
Findings of this study suggest that components to promote structure and regularity, including having breakfast and the number of food and drink moments, may be important to include in programs to prevent dental caries in children.
研究生活方式因素以及9岁、15岁和21岁人群的人口统计学特征对龋齿经历的影响。
数据取自“荷兰儿童和青少年口腔健康”研究。通过问卷调查和临床口腔检查收集数据。由于DMFS计数数据严重偏态且峰值为零，因此采用负二项式障碍模型进行分析。障碍模型的第一部分预测有或无龋齿经历的概率，第二部分预测龋齿经历的程度。
对于9岁和15岁年龄组，每周吃早餐的频率与是否有龋齿经历有关，而每天刷牙的频率与龋齿经历的程度有关。此外，每天食用的食物和饮料数量对较年轻年龄组很重要。在21岁年龄组中未发现这些关系。
本研究结果表明，促进结构和规律性的因素，包括吃早餐以及饮食次数，可能是儿童龋齿预防项目中重要的组成部分。
