青少年经常使用社交媒体,并且是面临性传播感染(STI)重大风险的一个群体。尽管有证据表明互联网可有效地用于支持健康的性行为,但这尚未延伸至社交网站。 为了确定通过脸书传递的性传播感染预防信息在预防2个月和6个月时性风险行为增加方面是否有效。 整群随机对照试验,2010年10月 - 2011年5月。 在多种环境(线上、通过报纸广告以及面对面)招募的个体(种子成员)被要求招募三名朋友,这些朋友进而再招募其他朋友,从种子成员开始延伸三轮。种子成员和各轮朋友被视为网络,并暴露于干预组或对照组条件下。 接触“Just/Us”(一个根据青少年意见开发的脸书页面),或接触“18 - 24新闻”(一个包含时事新闻的脸书页面)上的对照内容,为期2个月。 最近一次性行为中使用避孕套的情况以及使用避孕套的性行为比例。采用嵌套数据的重复测量来模拟接触“Just/Us”的主效应以及治疗与时间的交互作用。 1578名参与者报名,其中14%为拉丁裔,35%为非裔美国人;75%的参与者至少完成了一次研究随访。在2个月时观察到治疗与时间的效应,在使用避孕套方面(干预组68%对比对照组56%,p = 0.04)以及使用避孕套的性行为比例方面(干预组63%对比对照组57%,p = 0.03),干预参与降低了随着时间推移避孕套使用减少的趋势。在6个月时未观察到效应。 社交网站可能是有效的健康教育干预的场所。需要更多的工作来了解社交媒体的哪些元素具有吸引力,网络成员身份如何影响效果,以及将社交媒体与临床和社会服务相联系是否有益。 本研究在www.clinicaltrials.gov注册,注册号为NCT00725959。
Youth are using social media regularly and represent a group facing substantial risk for sexually transmitted infection (STI). Although there is evidence that the Internet can be used effectively in supporting healthy sexual behavior, this hasn't yet extended to social networking sites. To determine whether STI prevention messages delivered via Facebook are efficacious in preventing increases in sexual risk behavior at 2 and 6 months. Cluster RCT, October 2010–May 2011. Individuals (seeds) recruited in multiple settings (online, via newspaper ads and face-to-face) were asked to recruit three friends, who in turn recruited additional friends, extending three waves from the seed. Seeds and waves of friends were considered networks and exposed to either the intervention or control condition. Exposure to Just/Us, a Facebook page developed with youth input, or to control content on 18–24 News, a Facebook page with current events for 2 months. Condom use at last sex and proportion of sex acts protected by condoms. Repeated measures of nested data were used to model main effects of exposure to Just/Us and time by treatment interaction. 1578 participants enrolled, with 14% Latino and 35% African-American; 75% of participants completed at least one study follow-up. Time by treatment effects were observed at 2 months for condom use (intervention 68% vs control 56%, p=0.04) and proportion of sex acts protected by condoms (intervention 63% vs control 57%, p=0.03) where intervention participation reduced the tendency for condom use to decrease over time. No effects were seen at 6 months. Social networking sites may be venues for efficacious health education interventions. More work is needed to understand what elements of social media are compelling, how network membership influences effects, and whether linking social media to clinical and social services can be beneficial. This study is registered at www.clinicaltrials.gov NCT00725959.
