Korean society is afflicted with rapid aging. Aging is a risk factor for pain, and pain can reduce patients' quality of life. Thus, adequate management and monitoring of changing trends accompanying the demographic shift are highly valuable. However, this study was conducted because no studies have investigated the recent changes in the prevalence of pain.
The extent of the prevalence of pain was determined by questions related to quality of life based on the data derived from the Korea National Health and Nutrition Survey (KNHNS) from 2005 to 2016. The annual frequencies of the pain group and severe pain group were calculated using the survey questionnaire. Multiple logistic regression analysis was performed to determine possible differences in prevalence by year.
The prevalence of pain in all populations was 30.6% in 2005 and 18.9% in 2016. The average prevalence from 2005 to 2016 was 21.9%. A declining trend occurred over time with an odds ratio of 0.929 per year (95% CI: 0.921-0.938). The prevalence of severe pain was 2.35% in 2005 and 1.88% in 2016. Likewise, a decrease was observed over time, with an odds ratio of 0.920 per year at 95% CI 0.901-0.939. The decline in age-/sex-stratified analysis also showed a statistically significant trend in all groups.
The prevalence of pain in Korean society, based on the KNHNS, has declined since 2005. Such a trend was observed in all ages and sexs, and was most significant in the elderly.
韩国社会正面临快速老龄化。老龄化是疼痛的一个风险因素，而疼痛会降低患者的生活质量。因此，对伴随人口结构变化的趋势进行充分管理和监测具有很高的价值。然而，开展本研究是因为尚无研究调查疼痛患病率的近期变化情况。
基于2005年至2016年韩国国家健康与营养调查（KNHNS）的数据，通过与生活质量相关的问题来确定疼痛患病率的程度。使用调查问卷计算疼痛组和重度疼痛组的年度发生率。进行多因素逻辑回归分析以确定患病率随年份的可能差异。
2005年所有人群的疼痛患病率为30.6%，2016年为18.9%。2005年至2016年的平均患病率为21.9%。随着时间推移出现下降趋势，每年的优势比为0.929（95%置信区间：0.921 - 0.938）。2005年重度疼痛患病率为2.35%，2016年为1.88%。同样，随着时间观察到下降情况，95%置信区间为0.901 - 0.939时每年的优势比为0.920。年龄/性别分层分析中的下降在所有组中也显示出具有统计学意义的趋势。
基于KNHNS，韩国社会的疼痛患病率自2005年以来有所下降。这种趋势在所有年龄和性别中均有观察到，在老年人中最为显著。
