Abstract

IMPORTANCE

As society is increasingly becoming more networked, researchers are beginning to explore how social media can be used to study person-to-person communication about health and health care use. Twitter is an online messaging platform used by more than 300 million people who have generated several billion Tweets, yet little work has focused on the potential applications of these data for studying public attitudes and behaviors associated with cardiovascular health.

OBJECTIVE

To describe the volume and content of Tweets associated with cardiovascular disease as well as the characteristics of Twitter users.

DESIGN, SETTING, AND PARTICIPANTS: We used Twitter to access a random sample of approximately 10 billion English-language Tweets originating from US counties from July 23, 2009, to February 5, 2015, associated with cardiovascular disease. We characterized each Tweet relative to estimated user demographics. A random subset of 2500 Tweets was hand-coded for content and modifiers.

MAIN OUTCOMES AND MEASURES

The volume of Tweets about cardiovascular disease and the content of these Tweets.

RESULTS

Of 550 338 Tweets associated with cardiovascular disease, the terms diabetes (n = 239 989) and myocardial infarction (n = 269 907) were used more frequently than heart failure (n = 9414). Users who Tweeted about cardiovascular disease were more likely to be older than the general population of Twitter users (mean age, 28.7 vs 25.4 years; P < .01) and less likely to be male (59 082 of 124 896 [47.3%] vs 8433 of 17 270 [48.8%]; P < .01). Most Tweets (2338 of 2500 [93.5%]) were associated with a health topic; common themes of Tweets included risk factors (1048 of 2500 [41.9%]), awareness (585 of 2500 [23.4%]), and management (541 of 2500 [21.6%]) of cardiovascular disease.

CONCLUSIONS AND RELEVANCE

Twitter offers promise for studying public communication about cardiovascular disease.

摘要

重要性

随着社会日益网络化，研究人员开始探索如何利用社交媒体来研究关于健康和医疗保健使用的人际交流。推特是一个在线消息平台，有超过3亿人使用，他们发布了数十亿条推文，但很少有工作聚焦于这些数据在研究与心血管健康相关的公众态度和行为方面的潜在应用。

目的

描述与心血管疾病相关的推文数量和内容，以及推特用户的特征。

设计、背景和参与者：我们利用推特获取了2009年7月23日至2015年2月5日期间源自美国各县、与心血管疾病相关的约100亿条英语推文的随机样本。我们根据估计的用户人口统计学特征对每条推文进行了描述。对2500条推文的随机子集进行了内容和修饰词的人工编码。

主要结果和测量指标

关于心血管疾病的推文数量以及这些推文的内容。

结果

在与心血管疾病相关的550338条推文中，“糖尿病”（n = 239989）和“心肌梗死”（n = 269907）这两个词的使用频率高于“心力衰竭”（n = 9414）。发布关于心血管疾病推文的用户比推特用户总体更可能年龄较大（平均年龄，28.7岁对25.4岁；P < 0.01），且男性可能性较小（124896人中的59082人[47.3%]对17270人中的8433人[48.8%]；P < 0.01）。大多数推文（2500条中的2338条[93.5%]）与健康主题相关；推文的常见主题包括心血管疾病的危险因素（2500条中的1048条[41.9%]）、认知（2500条中的585条[23.4%]）和管理（2500条中的541条[21.6%]）。
