RESUMO
INTRODUCTION: Image-based social media Instagram, Pinterest, Tumblr, and Flickr have become sources of health-related information and tools for health communication. No known systematic review exists that summarizes the existing research and its health implications. METHODS: We searched EBSCOhost Academic Search Complete, PubMed, and Web of Science in January 2016, April 2017, and November 2017, with the following keywords: Pinterest, Instagram, Tumblr, or Flickr. Only public health-related, peer-reviewed research articles were included (excluding surveys of self-reported social media use). RESULTS: Sixty-six research articles were included. All 12 experimental studies used Instagram. Of the 54 observational studies, 38 studied Instagram; 12, Pinterest; 7, Tumblr; and 6, Flickr; some studies investigated more than 1 platform. More than half of the included articles were related to mental health and substance abuse (n = 39, 59%). Other topics included chronic diseases, infectious diseases, surgery, injury prevention, pharmacovigilance, sexual and reproductive health, and adolescent psychology with functional magnetic resonance imaging. DISCUSSION: Public health-oriented research on Instagram, Pinterest, Tumblr, and Flickr is increasing. Most observational studies investigated questions ranging from public perception of diseases or interventions (vaccination) and undesirable media exposure ("echo chamber," distorted body image, underage substance use, and pro-suicide messages) to information dissemination and online engagement (likes and comments). A few studies attempted to use image-based social media as intervention tools, but the results were mainly exploratory. CONCLUSION: More research is needed to study how social media users discuss health through sharing images online, and how public health professionals can communicate effectively using image-sharing social media.
RESUMO
CONTEXT: Communal blogs facilitate online narratives by providing opportunities for individuals to co-construct meaning and to engage in discussion about lived health experiences. OBJECTIVE: To examine the role of health as a connective narrative among individuals organizing collectively in an online community. The "We are the 99 percent" Tumblr blog emerged as a spontaneous community platform of the Occupy Wall Street movement in the US. DESIGN: Researchers conducted a qualitative content analysis of a total of 2003 blog posts. MAIN OUTCOME MEASURES: Data analysis included a process of data reduction, display, and conclusion drawing and verification. RESULTS: Bloggers discussed medical crises and the role of injury and illness in maintaining financial solvency. The difficulty of obtaining health care and the lack of accessible quality care emerged as themes. In particular, unemployment and underemployment limited access to health insurance coverage. The bloggers expressed dissatisfaction with the health care system and the impact of financial status on health. These challenges were exacerbated for marginalized populations, such as women and veterans. CONCLUSION: Findings offer implications for the value of online narrative to improve health care initiatives and to provide insight to integrated health care systems, including health care practitioners, nonprofit organizations, hospitals, and policy makers. Results suggest opportunities to address the health care gaps of marginalized populations and to develop public health policy.
