Further research is needed to harness the potential positive health impact of social media influencers, while mitigating against harmful effects.Ĭopyright © 2023 The Authors. We conclude that social media influencers have both negative and positive impacts on health outcomes, with negative impacts seen consistently in studies of body image dissatisfaction. Most of the published studies are of poor methodological quality with poor generalisability and statistical weaknesses. Public health campaigns harnessing influencers to promote hygiene habits in the context of COVID-19 and influenza showed some positive changes in health behaviours. Anxiety caused by viewing idealised portrayals of motherhood was the same whether or not the portrayal was by an influencer. Exposure to idealised influencer body imagery had statistically significant negative impacts on body image and mood. When an unhealthy food is marketed by an influencer of unhealthy appearance, this led to an increased preference for healthy snacks. Influencer marketing of unhealthy foods had a statistically significant effect on increasing children's immediate energy intake, but no effect was found for influencer promotion of vegetables. We identified twelve studies across four areas that met the inclusion criteria: children's dietary behaviour (n = 5), body image dissatisfaction (n = 4), influenza and COVID-19 (n = 2), and social comparison and anxiety (n = 1). But remember, it depends on the quality of content the child is watching. We assessed quality using a critical appraisal checklist for quasi-experimental studies. A positive media impact on teenagers can also positively influence their behavior and attitude, which can be observed in the following ways (1) (2). We used narrative synthesis to summarise the characteristics and main findings of studies within each of four main topic areas. We included interventional study designs which examined the effect of social media influencer as the primary or only exposure on a quantified health outcome. Two reviewers independently screened titles and abstracts. A systematic search of six databases (Medline, Embase, PsycINFO, CINAHL, Science Citation Index and Sociology Collection) was conducted in October 2021, with an update search in January 2023. Among US-based 13- to 17-year-olds, 94 use one or more SMPs (AP-NORC, 2017b). (Hanna, aged 17) Social media is intertwined with daily lifefor school-aged teens in developed countries, interacting with and through social media platforms (SMPs) is just part of the routine. The aim of this research was to systematically synthesise evidence on the impact of social media influencers on health outcomes. Social media really impacts my life a lot, from morning to night. The risks might be related to how much social media teens use. A fast emerging area of public health interest is the potential role of social media influencers in spreading health information and affecting health behaviour. However, social media use can also negatively affect teens, distracting them, disrupting their sleep, and exposing them to bullying, rumor spreading, unrealistic views of other people's lives and peer pressure.
