Medical journals increasingly promote published content through social media platforms such as Twitter. However, gastroenterology journals still rank below average in social media engagement.
We aimed to determine the engagement patterns of publications in gastroenterology journals on Twitter and evaluate the impact of tweets on citations.
This was a retrospective cohort study comparing the 3-year citations of all full-length articles published in five major gastroenterology journals from January 1, 2012, to December 31, 2012, tweeted by official journal accounts with those that were not. Multivariate analysis using linear regression was performed to control for journal impact factor, time since publication, article type, frequency of reposting by other users ("retweets"), and media addition to tweets. Secondary analyses were performed to assess the associations between article type or subtopic and the likelihood of social media promotion/engagement.
A total of 1666 articles were reviewed, with 477 tweeted by the official journal account. Tweeting an article independently predicted increased citations after controlling for potential confounders (β coefficient=13.09; P=.007). There was significant association between article type and number of retweets on analysis of variance (ANOVA) (P<.001), with guidelines/technical reviews (mean difference 1.04, 95% CI 0.22-1.87; P<.001) and meta-analyses/systemic reviews (mean difference 1.03, 95% CI 0.35-1.70; P<.001) being retweeted more than basic science articles. The manuscript subtopics most frequently promoted included motility/functional bowel disease (odds ratio [OR] 3.84, 95% CI 1.93-7.64; P<.001) and education (OR 4.69, 95% CI 1.62-13.58; P=.004), while basic science papers were less likely tweeted (OR 0.154, 95% CI 0.07-0.34; P<.001).
Tweeting of gastroenterology journal articles independently predicted higher 3-year citations. Wider adoption of social media to increase reach and measure uptake of published research should be considered.
医学期刊越来越多地通过 Twitter 等社交媒体平台来宣传已发表的内容。然而，胃肠病学期刊在社交媒体参与度方面仍排名较低。
我们旨在确定胃肠病学期刊在 Twitter 上发表的出版物的参与模式，并评估推文对引文的影响。
这是一项回顾性队列研究，比较了 2012 年 1 月 1 日至 12 月 31 日期间在五本主要胃肠病学期刊上发表的所有全长文章的 3 年引文，这些文章由官方期刊账户发布，未发布推文的文章作为对照组。使用线性回归的多变量分析来控制期刊影响因素、发表时间、文章类型、其他用户（“转发”）重新发布的频率以及推文的媒体附加内容。进行二次分析以评估文章类型或子主题与社交媒体推广/参与的可能性之间的关联。
共审查了 1666 篇文章，其中 477 篇由官方期刊账户发布。在控制潜在混杂因素后，发布文章可独立预测引文增加（β系数=13.09；P=.007）。方差分析（ANOVA）显示文章类型与转发数量之间存在显著关联（P<.001），指南/技术评论（平均差异 1.04，95%CI 0.22-1.87；P<.001）和荟萃分析/系统评价（平均差异 1.03，95%CI 0.35-1.70；P<.001）比基础科学文章被转发的次数更多。最常被宣传的手稿子主题包括运动/功能性肠病（优势比[OR]3.84，95%CI 1.93-7.64；P<.001）和教育（OR 4.69，95%CI 1.62-13.58；P=.004），而基础科学论文发布的推文较少（OR 0.154，95%CI 0.07-0.34；P<.001）。
胃肠病学期刊文章的发布推文可独立预测更高的 3 年引文。应考虑更广泛地采用社交媒体来增加发表研究的传播范围并衡量其接受程度。
