2015年，90%的美国年轻人使用社交媒体。数字和社交媒体是非常流行的模式，通过这些模式，年轻人探索身份形成，并通过扩展，学习和传播有关健康和风险行为的规范。目的：这项研究的目的是提供2014年至2016年社交媒体使用的最新估计，以及从一个国家收集的数据中社交媒体使用和数字技术使用的相关性。方法：在Truth Initiative Young Adult Cohort Study的第7波（2014年10月，N=1259）和第9波（2016年2月，N=989）中，年龄在18-24岁的年轻成年人参与者被问及11个社交媒体网站的使用频率和数字设备的访问，以及社会人口特征。定期使用被定义为至少每周使用一次给定的社交媒体网站。加权分析估计了每个社交媒体网站的使用率，定期使用特定网站之间的重叠，以及定期使用更多社交媒体网站的相关性。双变量分析确定了访问特定数字设备的社会人口统计学相关性。结果：在2014年，89.42%（加权n，1126/1298）的年轻人报告定期使用至少一个社交媒体网站。2016年，这一比例增加到97.5%（加权n，965/989）。在2016年社交媒体网站的常规用户中，排名前五的网站是Tumblr（85.5%），Vine（84.7%），Snapchat（81.7%），Instagram（80.7%）和LinkedIn（78.9%）。受访者平均定期使用7.6个社交媒体网站，其中85%的人定期使用6个或更多网站。总体而言，87%的年轻人报告访问或使用智能手机上网，74%的台式机或笔记本电脑上网，41%的平板电脑上网，29%的智能电视或视频游戏机上网，11%的手机没有上网，3%的人没有上网。访问所有的数字设备与互联网是较低的那些报告较低的主观财务状况，也有显着差异，在访问特定的数字设备与互联网的种族，民族，和education.Conclusions：高平均数的社交媒体网站经常使用和大量的重叠使用多个社交媒体网站反映了迅速变化的社交媒体环境。移动的设备是社交媒体的主要渠道，我们的研究强调了美国年轻人在种族/民族、教育和主观财务状况方面获得数字技术和互联网接入的差异。这项研究的结果可以指导未来通过互联网或社交媒体网站为年轻人提供的健康干预措施的制定和实施。
Background: In 2015, 90% of US young adults with Internet access used social media. Digital and social media are highly prevalent modalities through which young adults explore identity formation, and by extension, learn and transmit norms about health and risk behaviors during this developmental life stage.Objective: The purpose of this study was to provide updated estimates of social media use from 2014 to 2016 and correlates of social media use and access to digital technology in data collected from a national sample of US young adults in 2016.Methods: Young adult participants aged 18-24 years in Wave 7 (October 2014, N=1259) and Wave 9 (February 2016, N=989) of the Truth Initiative Young Adult Cohort Study were asked about use frequency for 11 social media sites and access to digital devices, in addition to sociodemographic characteristics. Regular use was defined as using a given social media site at least weekly. Weighted analyses estimated the prevalence of use of each social media site, overlap between regular use of specific sites, and correlates of using a greater number of social media sites regularly. Bivariate analyses identified sociodemographic correlates of access to specific digital devices.Results: In 2014, 89.42% (weighted n, 1126/1298) of young adults reported regular use of at least one social media site. This increased to 97.5% (weighted n, 965/989) of young adults in 2016. Among regular users of social media sites in 2016, the top five sites were Tumblr (85.5%), Vine (84.7%), Snapchat (81.7%), Instagram (80.7%), and LinkedIn (78.9%). Respondents reported regularly using an average of 7.6 social media sites, with 85% using 6 or more sites regularly. Overall, 87% of young adults reported access or use of a smartphone with Internet access, 74% a desktop or laptop computer with Internet access, 41% a tablet with Internet access, 29% a smart TV or video game console with Internet access, 11% a cell phone without Internet access, and 3% none of these. Access to all digital devices with Internet was lower in those reporting a lower subjective financial situation; there were also significant differences in access to specific digital devices with Internet by race, ethnicity, and education.Conclusions: The high mean number of social media sites used regularly and the substantial overlap in use of multiple social media sites reflect the rapidly changing social media environment. Mobile devices are a primary channel for social media, and our study highlights disparities in access to digital technologies with Internet access among US young adults by race/ethnicity,education, and subjective financial status. Findings from this study may guide the development and implementation of future health interventions for young adults delivered via the Internet or social media sites.
