BMJ:女性第-作者在高影响力医学期刊的论文发表情况研究

2016-03-07 MedSci MedSci原创

目的:为了评估1994-2014年女性为原始研究的第一作者发表在高影响力综合医学期刊上的数量变化,并调查不同期刊间的差距。

目的:为了评估1994-2014年女性为原始研究的第一作者发表在高影响力综合医学期刊上的数量变化,并调查不同期刊间的差距。


这是一个观察性研究。研究样本为1994年到2014年每隔一个月出版在《内科学年鉴》(Annals of Internal Medicine),《内科学档案》(Archives of Internal Medicine),《英国医学杂志》(BMJ)、《美国医学会杂志》(JAMA)、《新英格兰杂志》(NEJM)上的原始研究。主要暴露因素为时间和出版的期刊。

主要结局测量:女性为第一作者的数量和调整时间和期刊后的数量,使用多变量逻辑回归模型计算作者数量,研究类型和专业/主题,研究进行的地点,出版期刊和时间,研究类型,地点之间的相互关系。使用模型估算的数据计算6个期刊调整的风险比,使用95%可信区间和P值来描述相关性。

结局:在3860篇文献中,考虑第一作者性别的文章有3758篇,其中1273(34%)篇第一作者为女性。调整后,女性第一作者从1994年的27%显著增加到2014年的37%(P < 0.001)。NEJM似乎有不同的模式,女性第一作者数量减少;BMJ最近几年数量似乎也下降了,但BMJ拥有最高的女性第一作者比例。比较所有6个期刊,研究期间NEJM上的女性第一作者明显要少 (调整后的优势比为0.68,95%CI 0.53到0.89),女性第一作者更有可能出现在BMJ上 (1.30,1.01,1.66)。

结论:2014年女性为原始研究的第一作者发表在高影响力综合医学期刊上的数量较20年前显著增高,在近几年趋于平衡,并在几个期刊中有下降趋势。这些结果,以及在不同期刊间的重要差异,表明了女性为研究代表人发表高影响力期刊的的名额不够, 这仍是一个重要的问题。需要对潜在的原因进行调查,帮助确定经验和策略来提高女性在决定未来的临床策略和实践标准上的贡献和影响力。

心血管病是当今威胁女性生命和健康的主要疾病。中国的女性死因排序中,因心脏病死亡已超过了脑卒中和肿瘤,成为首位死亡原因。发达国家的男性冠心病患者的病死率已呈下降趋势。   但多年以来,女性的心血管病的研究和预防工作一直受到相对的忽视,女性的猝死发生率有逐渐升高的趋势。根据美国的资料,女性的猝死率从1989年的38%升至1999年的47%,女性在到达医院前猝死者多于男性(52%比42%)
