In Korea, the price of a pack of cigarettes increased 80% from US$2.2 to US$4 in 2015. The smoking rate decreased in 2015. However, it rebounded in the following year. To evaluate the characteristics associated with this rebound in smoking rate following the price increase. We analysed the KNHANES (Korean National Health and Nutrition Examination Survey) data of 44 015 participants to evaluate current smoking rate and the proportion of smokers planning to quit within 6 months from 2010 to 2016. We also performed focused analysis of 18 303 participants between 2014 and 2016 KNHANES to determine the current smoking rate according to their demographic and socio-economic characteristics. Individuals who were older, female, unemployed, had a low household income or a shorter total smoking period, or smoked less per day were more likely to stop or reduce smoking after the price increase. The current smoking rate increased to 18.8% in 2016 from 17.7% in 2015; this difference was significant in men, those in the lower-middle quartile of household income, those with a middle-school or college education, and those who were employed. The rebound in smoking after the price increase was significantly related to the individual's sex, income, education and employment status.
在韩国，2015 年香烟的价格从 2.2 美元上涨到 4 美元，涨幅达到 80%。2015 年的吸烟率有所下降。然而，这一趋势在次年出现了反弹。为了评估在价格上涨后吸烟率反弹的特征，我们分析了 44015 名参与者的 KNHANES（韩国国家健康和营养检查调查）数据，以评估 2010 年至 2016 年的当前吸烟率和计划在 6 个月内戒烟的吸烟者比例。我们还对 2014 年至 2016 年 KNHANES 的 18303 名参与者进行了重点分析，以根据他们的人口统计学和社会经济特征确定当前的吸烟率。在价格上涨后，年龄较大、女性、失业、家庭收入较低或总吸烟时间较短、每天吸烟量较少的人更有可能停止或减少吸烟。2016 年的当前吸烟率从 2015 年的 17.7%上升到 18.8%；这一差异在男性、家庭收入处于中下四分位的人群、中学或大学教育程度的人群以及就业人群中显著。价格上涨后吸烟的反弹与个人的性别、收入、教育和就业状况显著相关。
