Abstract：
This study aimed to explore seasonal variations in temporomandibular disorder (TMD) prevalence in South Korea, utilizing nationwide population-based big data. Data corresponding to the Korean Standard Classification of Diseases code of K07.6, which identifies TMD, were extracted from the Health Insurance Review and Assessment Service online platform for the period from 2010 to 2022. Additionally, we integrated these data with climate temperature records from the Korean Meteorological Administration. We subsequently conducted a statistical analysis of TMD patient data on a monthly and seasonal basis over the past 13 years to assess prevalence. Over the past 13 years, the number of TMD patients in Korea has steadily increased. The prevalence of TMD rose from 0.48% (224,708 out of a total population of 50,515,666) in 2010 to 0.94% (482,241 out of a total population of 51,439,038) in 2022, marking a 1.96-fold increase. Among children under 10 years of age, no significant differences were observed in TMD prevalence between boys and girls. However, a distinct female predominance emerged after the age of 10, with an average female-to-male ratio of 1.51:1. The peak prevalence of TMD occurred in individuals in their 20 s, followed by adolescents in their late 10 s. The majority of TMD patients were concentrated in Seoul and Gyeonggi province, with metropolitan areas accounting for 50% of the total patient count. Seasonally, TMD patient numbers showed no significant increase in winter compared with spring or summer. The temperature difference, defined as the absolute difference between the highest and lowest temperatures for each month, showed a positive correlation with TMD patient counts. A greater temperature difference was associated with higher patient counts. The strongest correlation between temperature differences and TMD patient numbers was observed in winter (r = 0.480, p < 0.01), followed by summer (r = 0.443, p < 0.01), and spring (r = 0.366, p < 0.05). Temperature differences demonstrated a significantly stronger correlation with the increase in the number of TMD patients than absolute climate temperatures. This aspect should be a key consideration when examining seasonal trends in TMD prevalence in South Korea.
摘要：
这项研究旨在探索韩国颞下颌关节紊乱病（TMD）患病率的季节性变化。利用全国人口大数据。对应于K07.6的韩国标准疾病分类代码的数据，该代码标识TMD，从2010年至2022年期间的健康保险审查和评估服务在线平台中提取。此外,我们将这些数据与韩国气象局的气候温度记录相结合。随后，我们对过去13年的每月和季节性TMD患者数据进行了统计分析，以评估患病率。在过去的13年里,韩国的TMD患者数量稳步增加。TMD的患病率从2010年的0.48％（占总人口50,515,666的224,708）上升到2022年的0.94％（占总人口51,439,038的482,241），增长了1.96倍。在10岁以下的儿童中，男孩和女孩的TMD患病率无显著差异.然而,10岁后出现明显的女性优势，平均男女比例为1.51:1。TMD的流行高峰发生在20多岁的个体中，其次是10多岁的青少年。大多数TMD患者集中在首尔和京处理过程中，大都市地区占患者总数的50%。季节性,与春季或夏季相比，冬季TMD患者人数没有显着增加。温差,定义为每个月最高和最低温度之间的绝对差，与TMD患者计数呈正相关。较大的温度差与较高的患者计数相关。在冬季观察到温度差异与TMD患者数量之间的最强相关性（r=0.480，p<0.01），其次是夏季(r=0.443，p<0.01)，和弹簧（r=0.366，p<0.05）。与绝对气候温度相比，温度差异与TMD患者人数增加的相关性显着增强。在研究韩国TMD患病率的季节性趋势时，这方面应该是一个关键的考虑因素。
