BACKGROUND The purpose of this study was to confirm that inequalities in community-level social economic status (SES) do actually impact the incidence of ischemic heart disease (IHD) using the Korean population-based cohort study of the National Health Insurance Service-National Sample Cohort (NHIS-NSC) database. METHODS This study used the NHIS-NSC database, a population-based cohort database established by the NHIS in South Korea. Community-level SES was classified into three categories, i.e. low, moderate, and high, according to the rank. The outcome measure of interest was IHD, which was defined according to the International Classification of Disease, 10th Revision (ICD-10) codes. RESULTS In the low community-level SES group, the incidence of IHD was 3.56 per 1000 person years (cumulative incidence rate, 1.78%), and in the high community level SES group, it was 3.13 per 1000 person years (cumulative incidence rate, 1.57%). Multivariate analysis showed that the incidence of IHD was higher in the low community-level SES group (p = 0.029). The log-rank test showed that the cumulative incidence of IHD was higher in the low community level SES group than the high community-level SES group (adjusted hazard ratio, 1.16; 95% CI, 1.01-1.32). CONCLUSIONS People living in areas with low community-level SES show an increased incidence of IHD. Therefore, intervention in active, health-risk behavior corrections at the local level will be required to reduce the incidence of IHD.

缺血性心脏病发病率的社区级社会经济不平等:一项全国性队列研究。

背景技术本研究的目的是使用韩国国民健康保险服务机构(National Sample)的队列研究来证实社区层面的社会经济地位(SES)的不平等确实确实影响了缺血性心脏病(IHD)的发病率。同类群组(NHIS-NSC)数据库。方法本研究使用了NHIS-NSC数据库,这是由NHIS在韩国建立的基于人群的队列数据库。根据等级,社区级别的SES分为三类,即低,中和高。感兴趣的结局指标是IHD,它是根据《国际疾病分类,第10版》(ICD-10)代码定义的。结果在低社区水平的SES组中,IHD的发生率为每1000人年3.56(累计发生率1.78%),在社区较高的SES组中,这一比例为每1000人年3.13(累计发生率1.57%)。多因素分析表明,在社区水平较低的SES组中,IHD的发生率较高(p = 0.029)。对数秩检验表明,低社区水平SES组中IHD的累积发生率高于高社区水平SES组(调整后的危险比,1.16; 95%CI,1.01-1.32)。结论生活在社区级SES较低的地区的人显示IHD发生率增加。因此,将需要在当地进行积极,健康风险行为纠正的干预措施,以减少IHD的发生。029)。对数秩检验表明,低社区水平SES组中IHD的累积发生率高于高社区水平SES组(调整后的危险比,1.16; 95%CI,1.01-1.32)。结论生活在社区级SES较低的地区的人显示IHD发生率增加。因此,将需要在当地进行积极,健康风险行为纠正的干预措施,以减少IHD的发生。029)。对数秩检验表明,低社区水平SES组中IHD的累积发生率高于高社区水平SES组(调整后的危险比,1.16; 95%CI,1.01-1.32)。结论生活在社区级SES较低的地区的人显示IHD发生率增加。因此,将需要在当地进行积极,健康风险行为纠正的干预措施,以减少IHD的发生。
