This study aimed to estimate the prevalence of current smoking among medical students in mainland China through a systematic search across 6 electronic databases for English or Chinese studies published before May 25, 2018. A total of 79 studies were included; 26 had a high risk of bias. The overall pooled prevalence of current smoking was 10.93% (7460/68 253; 95% confidence interval = 0.09%, 13.08%, I = 98.6%). This study found a decreasing prevalence of current smoking over the period studied (survey year range of 1988-2014). More specifically, the current smoking prevalence in males decreased progressively across time, while the prevalence in females remained relatively constant. The overall prevalence in the west was higher than in the middle or east of mainland China ( P = .0061). The overall prevalence of current smoking increased with year in school ( P = .0028). The present study provides a comprehensive synthesis of current smoking prevalence among medical students in mainland China. Although there have been some improvements in the status of tobacco use among medical students, given the leading role of physicians in tobacco control, sustained efforts are needed to curb the tobacco epidemic among medical students.
本研究旨在通过对截至 2018 年 5 月 25 日之前发表的英文或中文研究进行系统检索，估算中国大陆医学生当前吸烟的流行率。共纳入 79 项研究；其中 26 项存在高偏倚风险。当前吸烟的总体合并流行率为 10.93%（7460/68253；95%置信区间=0.09%，13.08%，I=98.6%）。本研究发现，在所研究期间，当前吸烟的流行率呈下降趋势（调查年份范围为 1988 年至 2014 年）。具体而言，男性当前吸烟的流行率随时间逐渐降低，而女性的流行率则相对保持不变。中国大陆西部地区的总体流行率高于中部和东部（P=0.0061）。总体上，在校年份与当前吸烟的流行率呈正相关（P=0.0028）。本研究综合了中国大陆医学生当前吸烟的流行率。尽管医学生的烟草使用状况有所改善，但鉴于医生在烟草控制方面的主导作用，仍需要持续努力遏制医学生中的烟草流行。
