While prior reviews have identified positive effects of social media interventions for health behavior change generally, it is unclear whether these effects persist in traditionally underrepresented populations that are at disproportionate risk of disease. The current meta-analysis examined the effectiveness of social media interventions for health behavior change among populations with health disparities. We analyzed 17 studies with a cumulative = 3,561. Social media interventions had a significant moderate-sized effect on behavior change among populations with health disparities ( = 0.303, 95% CI: 0.156, 0.460, < .001), and there was significant heterogeneity across the studies ( = 64.48, < .001, 75.19). Exploratory moderator analyses revealed larger effects in studies with smaller sample size ( < .05) and those using additional intervention channels, including e-mail and telephone ( < .05). Findings suggest that social media interventions may be a promising intervention tool for stimulating behavior change among populations with health disparities, but several gaps remain in the literature. Public health professionals and other health communicators should further explore ways to increase both the reach and impact of social media interventions among populations with health disparities.
虽然之前的综述已经确定了社交媒体干预措施对健康行为改变的积极影响，但尚不清楚这些影响是否会持续存在于那些疾病风险不成比例的代表性不足的人群中。本荟萃分析检查了社交媒体干预措施对健康差异人群健康行为改变的有效性。我们分析了 17 项研究，累计有 = 3561 人。社交媒体干预措施对健康差异人群的行为改变有显著的中等影响（ = 0.303，95%置信区间：0.156，0.460， < 0.001），且研究之间存在显著的异质性（ = 64.48， < 0.001，75.19）。探索性调节因素分析显示，样本量较小的研究（ < 0.05）和使用额外干预渠道（包括电子邮件和电话）的研究中，效果更大（ < 0.05）。研究结果表明，社交媒体干预措施可能是一种有前途的干预工具，可以促进健康差异人群的行为改变，但文献中仍存在一些空白。公共卫生专业人员和其他健康传播者应进一步探索增加健康差异人群社交媒体干预措施的覆盖面和影响力的方法。
