Purpose

To determine whether there is an association between e-cigarette use and visual impairment in the United States adult population.

Design

Cross-sectional.

Methods

In this population survey study, we reviewed 1,173,646 adults ≥18 years of age from all 50 United States and 3 U.S. territories with self-reported responses to the Center for Disease Control and Prevention's 2016-2018 Behavioral Risk Factor Surveillance System (BRFSS) annual telephone survey. We reviewed e-cigarette use (current, former, or never), as assessed by the questions: “Have you ever used an e-cigarette or other electronic vaping product, even just one time, in your entire life?” and “Do you now use e-cigarettes or other electronic vaping products every day, some days, or not at all?” The primary outcome measure was visual impairment, defined as a binary outcome “yes” or “no” to the question, “Are you blind or do you have serious difficulty seeing, even when wearing glasses?”

Results

After excluding missing data, there were 1,173,646 participants. The adjusted odds ratio of visual impairment in current e-cigarette users compared with never e-cigarette users was 1.34 (95% confidence interval [CI] 1.20-1.48), and in former e-cigarette users was 1.14 (95% CI 1.06-1.22). In the subgroup of 662,033 never users of traditional cigarettes (weighted 59.6% of study population), the adjusted odds ratio of visual impairment in current e-cigarette users compared with never e-cigarette users was 1.96 (95% CI 1.48-2.61) and in former e-cigarette users was 1.02 (95% CI 0.89-1.18).

Conclusions

Current compared with never e-cigarette usage was associated with a higher odds of visual impairment in the BRFSS 2016-2018 population, independent of traditional cigarette use.

美国电子烟使用与视力障碍之间的关联

目的

确定美国成年人口中电子烟使用与视力障碍之间是否存在关联。

设计

横截面。

方法

在这项人口调查研究中，我们审查了来自所有 50 个美国和 3 个美国领土的 1,173,646 名 18 岁以上的成年人，他们对疾病控制和预防中心的 2016-2018 年行为风险因素监测系统 (BRFSS) 年度电话进行了自我报告的回应民意调查。我们审查了电子烟的使用情况（当前、以前或从未），通过以下问题评估：“您一生中是否曾经使用过电子烟或其他电子烟产品，甚至只使用过一次？” 和“您现在每天、某些天或根本不使用电子烟或其他电子烟产品吗？” 主要结果衡量标准是视力障碍，定义为“是”或“否”这个问题的二元结果，“你是盲人还是视力严重困难，即使戴着眼镜？”

结果

剔除缺失数据后，共有 1,173,646 名参与者。当前电子烟用户与从未电子烟用户相比，视力障碍的调整优势比为 1.34（95% 置信区间 [CI] 1.20-1.48），以前电子烟用户为 1.14（95% CI 1.06- 1.22)。在 662,033 名从不使用传统卷烟的亚组中（占研究人群的 59.6% 的权重），当前电子烟用户与从不电子烟用户相比，视力障碍的调整优势比为 1.96（95% CI 1.48-2.61）和在前电子烟使用者中为 1.02 (95% CI 0.89-1.18)。

结论

当前与从未使用过电子烟相比，BRFSS 2016-2018 人群中视力障碍的几率更高，与传统卷烟使用无关。
