Abstract

Introduction: This study aimed to examine the effects of age, period (historical events), and cohort (generational impact) (APC) on caries prevalence and mean DMFT among Singapore schoolchildren from 2007 to 2019.

Methods: Anonymised records of all 6-year-old primary 1 (P1), 11-year-old primary 6 (P6), and 14-year-old secondary 3 (S3) students before the start of each school year between 2007 and 2019 were extracted from the Integrated Dental Electronic Assessment System (IDEAS), categorised by school level, ethnicity, and sex. Poisson regression and partial least squares regressions were applied to estimate APC effects.

Results: In total, 502,339 P1, 535,579 P6, and 496,725 S3 records were included from 2007 to 2019, with 1,058,589 (69.0%) Chinese, 187,948 (12.2%) Malay, and 152,618 (9.9%) Indian students; 245,447 (48.8%) P1, 259,389 (48.4%) P6, and 243,941 (49.1%) S3 students were girls. Overall, the APC effects on caries prevalence and mean DMFT showed a strong age effect, with the lowest prevalence in the youngest P1 group and the highest in the oldest S3 group. Period and cohort effects were identified, with the prevalence decreasing among those born after 1995 and the lowest prevalence rate in 2013. Similarly, period and cohort effects on mean DMFT were also detected, with decreased mean DMFT after period 2009 and the highest mean DMFT (0.72 in P6 and 1.13 in S3) in cohort 1995.

Conclusion: Caries prevalence and DMFT increased with age. While both decreased in individuals born after 1995, mean DMFT began to rise again in those born after 2003.

2007-2019年新加坡150多万份学童龋齿记录：年龄段-队列效应分析。

简介：本研究旨在探讨年龄、时期（历史事件）和队列（代际影响）--APC 对 2007 年至 2019 年新加坡学龄儿童龋齿患病率和平均 DMFT 的影响：从综合牙科电子评估系统（IDEAS）中提取了2007至2019年间每学年开学前所有6岁小一（P1）、11岁小六（P6）和14岁中三（S3）学生的匿名记录，并按学校级别、种族和性别进行了分类。采用泊松回归和偏最小二乘法（PLS）回归估算APC效应：从2007年到2019年，共纳入了502339个小一学生、535579个小六学生和496725个中三学生的记录，其中有1058589个（69.0%）华裔学生、187948个（12.2%）马来裔学生和152618个（9.9%）印度裔学生；245447个（48.8%）小一学生、259389个（48.4%）小六学生和243941个（49.1%）中三学生是女生。总体而言，APC 对龋齿患病率和平均 DMFT 的影响显示出强烈的年龄效应，年龄最小的 P1 组患病率最低，年龄最大的 S3 组患病率最高。研究还发现了时期和队列效应，1995 年后出生的学生患病率下降，2013 年的患病率最低。同样，还发现了时期和队列对平均 DMFT 的影响，2009 年后平均 DMFT 下降，1995 年队列的平均 DMFT 最高（P6 为 0.72，S3 为 1.13）：结论：龋齿患病率和 DMFT 随年龄增长而增加。结论：龋齿患病率和 DMFT 随年龄的增长而增加，1995 年后出生的人的平均 DMFT 有所下降，而 2003 年后出生的人的平均 DMFT 开始回升。

期刊介绍： ''Caries Research'' publishes epidemiological, clinical and laboratory studies in dental caries, erosion and related dental diseases. Some studies build on the considerable advances already made in caries prevention, e.g. through fluoride application. Some aim to improve understanding of the increasingly important problem of dental erosion and the associated tooth wear process. Others monitor the changing pattern of caries in different populations, explore improved methods of diagnosis or evaluate methods of prevention or treatment. The broad coverage of current research has given the journal an international reputation as an indispensable source for both basic scientists and clinicians engaged in understanding, investigating and preventing dental disease.
