Insulin resistance contributes to the development of cardiovascular disease and type 2 diabetes mellitus. Smoking leads to an increase in triglyceride levels, which, in turn, increases insulin resistance. Although the number of e-cigarette users has increased in recent years, few studies have investigated the association between ecigarette use and insulin resistance. Therefore, this study aimed to determine the association between e-cigarette use and insulin resistance using the triglyceride-glucose (TyG) index in Korean adults.
This study included 4,404 healthy adults aged ≥20 years who participated in the Korea National Health and Nutrition Examination Survey between 2019 and 2020. Participants were categorized as never-smokers or ecigarette users, and the TyG index was categorized into low- and high-TyG index groups according to the median value (9.22). A logistic regression analysis was performed to determine the association between e-cigarette smoking and insulin resistance.
E-cigarette users had a higher TyG index than never smokers (e-cigarette: mean=3.95; never: mean=9.18; P<0.001). The e-cigarette users had a higher risk of being in the high TyG index group than never-smokers (odds ratio [OR], 1.38; 95% confidence interval [CI], 1.03-1.84). In the subgroup analysis stratified by sex, age, and body mass index, a higher OR for a high TyG index was observed in men (OR, 1.46; 95% CI, 1.03-2.08) and individuals aged 60 years or older (OR, 3.74; 95% CI, 1.14-12.30).
Our findings suggest that e-cigarette use is significantly associated with insulin resistance.
胰岛素抵抗会促使心血管疾病和2型糖尿病的发展。吸烟会导致甘油三酯水平升高，进而增加胰岛素抵抗。尽管近年来电子烟使用者的数量有所增加，但很少有研究调查电子烟使用与胰岛素抵抗之间的关联。因此，本研究旨在利用甘油三酯-葡萄糖（TyG）指数确定韩国成年人中电子烟使用与胰岛素抵抗之间的关联。
本研究纳入了2019年至2020年期间参加韩国国民健康与营养检查调查的4404名年龄≥20岁的健康成年人。参与者被分为从不吸烟者或电子烟使用者，TyG指数根据中位数（9.22）分为低TyG指数组和高TyG指数组。进行逻辑回归分析以确定电子烟吸烟与胰岛素抵抗之间的关联。
电子烟使用者的TyG指数高于从不吸烟者（电子烟：平均值 = 3.95；从不吸烟者：平均值 = 9.18；P < 0.001）。与从不吸烟者相比，电子烟使用者处于高TyG指数组的风险更高（优势比[OR]，1.38；95%置信区间[CI]，1.03 - 1.84）。在按性别、年龄和体重指数分层的亚组分析中，男性（OR，1.46；95% CI，1.03 - 2.08）和60岁及以上的个体（OR，3.74；95% CI，1.14 - 12.30）的高TyG指数的OR更高。
我们的研究结果表明，电子烟使用与胰岛素抵抗显著相关。
