Background:The associations of changes in noncombustible nicotine or tobacco product (NNTP) and combustible cigarette (CC) use habits with subsequent cardiovascular disease (CVD) risk are still unclear.Methods:The study population consisted of 5 159 538 adult men who underwent health screening examinations during both the first (2014–2015) and second (2018) health screening periods from the Korean National Health Insurance Service database. All participants were divided into continual CC-only smokers, CC and NNTP users, recent (<5 years) CC quitters without NNTP use, recent CC quitters with NNTP use, long-term (≥5 years) CC quitters without NNTP use, long-term CC quitters with NNTP use, and never smokers. Propensity score matching analysis was conducted to further compare CVD risk among CC quitters according to NNTP use. Starting from the second health screening date, participants were followed up until the date of CVD event, death, or December 31, 2019, whichever came earliest. Multivariable Cox proportional hazards regression was used to determine the adjusted hazard ratios (aHRs) and 95% CIs for CVD risk according to changes in NNTP and CC smoking habits.Results:Compared with continual CC-only smokers, CC and NNTP users (aHR, 0.83 [95% CI, 0.79–0.88]) and initial CC smokers who quit CCs and switched to NNTP use only (recent CC quitters with NNTP use, aHR, 0.81 [95% CI, 0.78–0.84]) had lower risk for CVD. After propensity score matching, recent CC quitters with NNTP use (aHR, 1.31 [95% CI, 1.01–1.70]) had higher risk for CVD than recent CC quitters without NNTP use. Similarly, compared with long-term CC quitters without NNTP use, long-term CC quitters with NNTP use (aHR, 1.70 [95% CI, 1.07–2.72]) had higher CVD risk.Conclusions:Switching to NNTP use among initial CC smokers was associated with lower CVD risk than continued CC smoking. On CC cessation, NNTP use was associated with higher CVD risk than CC quitting without NNTPs. Compared with CC smokers who quit without NNTP use, CC quitters who use NNTPs may be at higher future CVD risk.

韩国男性不可燃尼古丁或烟草制品和可燃卷烟使用习惯的变化与随后的短期心血管疾病风险的综合关联:一项全国性队列研究

背景:不可燃尼古丁或烟草制品 (NNTP) 和可燃香烟 (CC) 使用习惯的变化与随后的心血管疾病 (CVD) 风险之间的关联仍不清楚。方法:研究人群包括 5 159 538 名接受过健康检查的成年男性来自韩国国民健康保险服务数据库的第一次(2014-2015 年)和第二次(2018 年)健康检查期间的筛查检查。所有参与者分为持续仅使用 CC 吸烟者、CC 和 NNTP 使用者、近期(<5 年)未使用 NNTP 的 CC 戒烟者、近期使用 NNTP 的 CC 戒烟者、长期(≥5 年)未使用 NNTP 的 CC 戒烟者、长期-term CC 戒烟者使用 NNTP,从不吸烟。进行了倾向评分匹配分析,以根据 NNTP 的使用进一步比较 CC 戒烟者的 CVD 风险。从第二次健康筛查日期开始,参与者被随访至 CVD 事件、死亡日期或 2019 年 12 月 31 日,以较早者为准。根据 NNTP 和 CC 吸烟习惯的变化,使用多变量 Cox 比例风险回归确定 CVD 风险的调整风险比 (aHR) 和 95% CI。 0.83 [95% CI, 0.79–0.88]) 和最初戒烟并改用 NNTP 的 CC 吸烟者(最近使用 NNTP 的 CC 戒烟者,aHR,0.81 [95% CI,0.78–0.84])CVD 风险较低. 在倾向评分匹配后,近期使用 NNTP 的 CC 戒烟者(aHR,1.31 [95% CI,1.01-1.70])比近期未使用 NNTP 的 CC 戒烟者有更高的 CVD 风险。同样,与不使用 NNTP 的长期 CC 戒烟者相比,长期使用 NNTP 的 CC 戒烟者(aHR,1.70 [95% CI,1.07-2.72])具有更高的 CVD 风险。结论:与继续使用 CC 相比,初始 CC 吸烟者改用 NNTP 与更低的 CVD 风险相关。在停止 CC 时,与不使用 NNTP 的 CC 戒烟相比,使用 NNTP 与更高的 CVD 风险相关。与未使用 NNTP 就戒烟的 CC 吸烟者相比,使用 NNTP 的 CC 戒烟者未来可能面临更高的 CVD 风险。
