To analyze the prevalence and years lived with disability (YLD) from dental caries among children and adolescents and the time trends over the past two decades in Sichuan province, the largest province in west China.
Based on the Global Burden of Disease Study 2015 (GBD2015), which systematically assessed the epidemiological characteristics of major diseases and their transitions by country and region from 1990 to 2015, we extracted the estimated results for China. We then used the Bayesian meta-regression method to estimate the sex- and age-specific prevalences and YLDs from dental caries among children and adolescents under 15 years old in Sichuan province and compared them with global and national indicators for the same period.
In 2015, there were almost 6 million cases of dental caries in children and adolescents (aged < 15 years) in Sichuan province, accounting for 6% of the total cases in China. For children under 5 years, the prevalence of deciduous caries was 55.9%, and the YLDs value was 10.8 per 100,000, while it was 24.3% and 5.1 per 100,000 respectively among 5- to 14-year-olds; for those aged 5 to 14 years, the prevalence of permanent caries was 21.5%, and the YLDs value was 11.5 per 100,000. From 1990 to 2015, the prevalence of dental caries for children under 5 years increased substantially, by 16.2%, and the YLDs increased by 8.7%. Among those aged 5 to 14 years, the prevalence increased and the YLDs decreased.
Dental caries remains a huge health burden in Western China. In contrast to the global and national data, the trend has increased rapidly over the past 25 years in this region. This work provides suggestions for the prevention and control for oral health in China with the policy of two-child.
分析中国西部最大省份四川省儿童和青少年龋齿的患病率及伤残调整生命年（YLD），以及过去二十年的时间趋势。
基于《2015年全球疾病负担研究》（GBD2015），该研究系统评估了1990年至2015年按国家和地区划分的主要疾病的流行病学特征及其转变情况，我们提取了中国的估计结果。然后，我们使用贝叶斯元回归方法来估计四川省15岁以下儿童和青少年龋齿的性别和年龄特异性患病率及YLD，并将其与同期的全球和国家指标进行比较。
2015年，四川省儿童和青少年（年龄<15岁）中龋齿病例近600万例，占中国总病例数的6%。5岁以下儿童乳牙龋齿患病率为55.9%，YLD值为每10万人10.8，而5至14岁儿童分别为24.3%和每10万人5.1；5至14岁儿童恒牙龋齿患病率为21.5%，YLD值为每10万人11.5。1990年至2015年，5岁以下儿童龋齿患病率大幅上升，上升了16.2%，YLD上升了8.7%。5至14岁儿童中，患病率上升而YLD下降。
龋齿在中国西部仍然是一个巨大的健康负担。与全球和国家数据相比，该地区在过去25年中这一趋势迅速上升。这项工作为中国二孩政策下的口腔健康预防和控制提供了建议。
