Increasing evidence indicates that cigarette smoking is a strong predictor of electronic cigarettes (e-cigarettes) use, particularly in adolescents, yet the effects has not be systematically reviewed and quantified. Relevant studies were retrieved by searching three databases up to June 2015. The meta-analysis results were presented as pooled odds ratios (ORs) with 95% confidence intervals (CIs) calculated by a random-effects model. Current smokers were more likely to use e-cigarette currently (OR: 14.89, 95% CI: 7.70-28.78) and the probability was greater in adolescents than in adults (39.13 vs. 7.51). The probability of ever e-cigarettes use was significantly increased in smokers (OR: 14.67, 95% CI: 11.04-19.49). Compared with ever smokers and adults, the probabilities were much greater in current smokers (16.10 vs. 9.47) and adolescents (15.19 vs. 14.30), respectively. Cigarette smoking increases the probability of e-cigarettes use, especially in current smokers and adolescents.
越来越多的证据表明，吸烟是使用电子烟的一个强有力的预测因素，尤其是在青少年中，但尚未对其影响进行系统的综述和量化。通过检索截至2015年6月的三个数据库获取相关研究。荟萃分析结果以合并比值比（OR）表示，并采用随机效应模型计算95%置信区间（CI）。当前吸烟者目前更有可能使用电子烟（OR：14.89，95%CI：7.70 - 28.78），且青少年的可能性大于成年人（39.13对7.51）。曾经吸烟的人使用电子烟的概率显著增加（OR：14.67，95%CI：11.04 - 19.49）。与曾经吸烟者和成年人相比，当前吸烟者（16.10对9.47）和青少年（15.19对14.30）的概率分别要高得多。吸烟会增加使用电子烟的概率，尤其是在当前吸烟者和青少年中。
