: Patient assistance with severe eating disorders (EDs) is covered in hospital institutions by the specialized service offered. To a lesser extent, these types of pathologies are treated from health prevention, and there are hardly any experiences of health promotion in EDs through social networks. The main objective of this study was to evaluate the effectiveness of the messages about ED spread on TikTok, particularly those disseminated by international hospitals. For this, a systematic review of the scientiﬁc literature has been conducted


Micro-Video
Nowadays, the industry of broadcasting short videos on the internet is living in its "golden age" and plays a key role in communication via social media [1]. With regard to TikTok, the increase in the use of this social media platform since its creation in 2016 has made it rank sixth in the world ranking of mobile applications in 2022 according to the Digital 2023 Report study published by WeareSocial and Meltwater [2]. In addition, the same study reflects the rise of TikTok to first place among social network applications by the average time of use per month per user throughout 2022. TikTok is the social media platform that allows users to create "micro-videos" (15" to 60") with music, filters and other elements that make them engage and currently maintains the fastest rate of expansion among social media [3]. Based on the report referred, which was published in 2023, the number of active TikTok users amounts to over one million monthly active users. These figures, according to the Digital 2023 Report, are lower than for Facebook, YouTube, WhatsApp, Instagram and WeChat but higher than the other platforms. In the XII Study of Social Media developed by IAB Spain [4], the significant increase in the introduction of TikTok in Spain is highlighted. Thus, video consumption has increased exponentially: Almost 9 out of 10 Spanish internet users are consumers of this type of If we look at mental illnesses, the Global Web Index 2021 study [19] warns of a clear correlation between the consumption of social media in particular and online news outlets with these pathologies, explaining the increase in prevalence to a large extent to situations of confinement and isolation of the population due to the pandemic. Social media influences the way in which social relationships are produced, as well as the configuration of personalities [20]. According to data published in 2021 by the Spanish Ministry of Health, the overall prevalence of mental health problems in Spain is 27.4% (30.2% in the case of women) with unemployed people being especially sensitive-a situation that has worsened during the pandemic.
As highlighted by the Eating Disorders Coalition (EDC) [21], eating disorders (EDs) are the second leading cause of death among mental illnesses after opium addiction. They argue that EDs can be successfully treated, but only a third of sufferers receive adequate healthcare, and at least 1 person dies every 62 min as a direct consequence of an eating disorder.
Galmiche et al. [22] draw attention to the growing prevalence of eating disorders. In their study carried out between 2000 and 2018, an overall increase of 3.5% in this type of disorder was recorded in the period between 2000 and 2006 and 7.8% between 2013 and 2018. For these researchers, the results represent a real health challenge.
The non-profit organisation Associació contra l'Anorèxia i la Bulímia (ACAB), which is driven by family members and specialists from the Hospital Clínic de Barcelona, warns that during confinement, the number of consultations on EDs have tripled.
Among the different types of EDs that are defined in the Diagnostic and Statistical Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) [23], anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder, unspecified eating disorder, non-nutritive substance intake, rumination disorder, among others, the first two are the most common according to the Spanish Society of Family and Community Medicine (SEMFYC). Among the characteristics of AN, Buitrago et al. [24] emphasise "the refusal to maintain a minimally normal body weight, fear of gaining weight and an altered perception of body shape or size". In the case of BN, the specialists describe "repeated episodes of excessive food intake and an exaggerated preoccupation with body weight control, leading the sufferer to adopt extreme compensatory measures".
In social networks where the ideal of beauty associated with thinness is widespread, unhealthy measures related to diet or disordered eating attitudes are promoted in order to achieve a change in body image associated with greater personal satisfaction, which is something unrealistic or unattainable [25]. The growing number of cases of inappropriate eating habits promoted by social media in an increasingly younger population in certain countries or geographical areas is a fact, as demonstrated by studies and reports on the subject endorsed or conducted by the World Health Organization and independent research [26,27]. Statistical studies reflect how EDs and TikTok have a common target audience, adolescents and young women, whose numbers doubled during the period of confinement due to the COVID-19 pandemic [28]. The topic of anorexia, as the most prevalent eating disorder, is "very common" on TikTok, as corroborated by these researchers who note that "while most "pro-ana" (pro-anorexia) videos, where users exchanged advice on how to pathologically lose weight, have been censored by the application, other "anti-proana" (anti-pro-anorexia) videos, officially aimed at raising awareness of the consequences of anorexia, have become increasingly popular" [29]. In one way or another, this content remains on the social media, which, according to Logrieco et al. [28], even in cases where it criticises and attacks pro-anorexia behaviours, this content pushes at-risk users to emulate behaviours that are harmful to their health, as both EDs and self-harming behaviours are present in the application, although in disguise. The authors believe that this type of content is shown to teenagers who are uncomfortable with their image and lack self-confidence, making it very easy to find messages that can be psychologically and physically harmful to the most fragile people.

Materials and Methods
Firstly, the methodological triangulation developed began with a systematic review of scientific literature related to hospital communication on aspects related to eating disorders via TikTok. Communication research on the social media platform TikTok is relatively recent considering that the history of this communication channel is about seven years old. Despite the large number of publications found, this is reduced if we limit the study to health communication via TikTok and, even more so, if we concentrate this activity on the field of hospital care and eating disorders as mental health disorders. The advances in research found in studies on EDs and their relationship with communication via social media have served, to a large extent, as a reference in the development of this article.
With the aim of presenting valid proposals that can be used by hospital institutions to offer prevention messages to the population or help patients with EDs and their families through micro-videos whose impact on society is increasing, two methodological tools have been used: Fanpagekarma and analisa.io. Data collection took place during the last quarter of 2021 for further analysis in 2022.
Since 2021, Fanpagekarma has offered the possibility of quantitatively analysing and comparing accounts on TikTok: rates of evolution, activity and interaction on the network, among other aspects. This tool was used to record the degree of interaction of hospital accounts with their followers, number of "likes", as well as other information about the corporate account (country, year in which it started its activity on TikTok and number of videos broadcast) ( Table 1). In addition, a qualitative content analysis of the videos was carried out in which different categories were determined into which these messages could be categorised following the classification made by Rando-Cueto et al. [18] in a previous study: information about the hospital; health information; health promotion; citizen service information; sale of products and services; recognition; social media and nonhealth information. An additional category was added to these: recruitment/employment of professionals since two hospitals use this social media to recruit staff [ Figure 1].
The interest of this methodological action lies in gathering objective data with which to evaluate the communicative activity of hospitals on TikTok, particularly in the field of prevention and health promotion, in order to assess the effect it has on the population.   countries where any of these languages are spoken, as well as from countries where the mother tongue is not European, but which have appeared in the search process.
On the other hand, the tool analisa.io was used to evaluate the sample of profiles of a total of 40 tiktokers. For the identification and selection of the sample, a search was developed in TikTok by hashtags using those published by Logrieco et al. [28]; Sukunesan et al. [33] and Maliguetti et al. [34] in previous studies on ED communication on social media. Other terms that were identified in the scientific literature analysed were added to these terms, as well as in the Eating Attitudes Test-26, a clinical test considered by the scientific community as a validated questionnaire for the detection of EDs [35]. In total, a list of 30 terms was compiled 1 .
These profiles were classified into three groups: A. Patients diagnosed with ED or presenting as such; B. Patients with ED who claim to be in the process of recovery from eating disorders according to their testimony and C. People who consider themselves to have the authority to advise or "guide" patients with the aforementioned disorders. The information collected was cross-checked with the data obtained by dividing the sample into influencers or "opinion leaders" in the online environment who have "a certain credibility on a specific topic and whose presence and influence in social media makes them an ideal prescriber" [36] and non-influencers. In this way, it was determined which groups have the largest number of followers.
In turn, the accounts and comments of three followers of each of the 40 selected tiktokers were analysed in order to expand the number of profiles analysed to a total of 160. The first three followers who had reacted and/or engaged in conversation with the original emisor and whose comments were understandable and related to the initial message were collected.
Based on the design of a codebook used to examine tweets from pro-ED profiles on Twitter [37], this was adapted for the analysis of profile videos on TikTok. In addition, quantitative information was recorded for these profiles: year of start of activity, gender, place of recording, objective description of the image and qualitative information following the classification of emotions made by Maliguetti et al. [34] for the description of tiktokers appearing in the videos. The set of 120 registered followers and their comments was reached using the methodological analysis technique "Snowball Sample" [38,39].

Results
Eighteen accounts of private health administrations were analysed, to which three ministries of public health were added in order to include the activity of public institutions in the health sector. All of them started their activity on TikTok in 2019 and have a number of followers which, except in the case of the account of the Orden Hospitalaria San Juan de Dios in Quito, exceeds half a thousand, with the Phyathai Hospital in Thailand and Klinikum Dortmund in Germany reaching around 80,000 and Sikarin Hospital in Thailand exceeding 100,000. Table 1 shows the TikTok accounts analysed, as well as their predominant content (ordered by prevalence), according to the classification previously referred to by the authors Rando-Cueto et al. [18] to which the term recruitment/employment has been added due to its appearance in the records analysed. In this way, the messages have been classified into the following contents: information on hospital activity (Hospital Information); information on health-related issues (Health Information); information on aspects not related to the hospital or health (Non-health Information); Testimonies; preventive measures (Prevention); Recruitment and Sale-of health products or services. Table 1 also shows other channels used by the healthcare institutions analysed (websites and social media) as a sample of their communication activity.
The number of followers does not always correspond to greater interaction from the receptors, with the Scandinavia Hospital Centre in Russia standing out in this respect. Nevertheless, the percentage of interaction is outstanding and is related to the number of followers and the number of "likes". For the calculation of this index, only the number of "likes" given to the publicly disseminated videos was considered in relation to the number of followers of the accounts. Neither the number of comments nor the number of videos shared have been accounted for so as not to duplicate the counting of interaction actions.
Considering the year in which the TikTok activity began, as well as the number of videos disseminated (an average of 64 videos per hospital in two years), the engagement figures of the followers of the hospital accounts that interact with the health institution stand out.
The content shown in the published videos is largely related to health prevention: 12 of the 21 accounts analysed ( Figure 1). The interaction achieved by these profiles based on the number of likes (no. likes/no. followers ×100) is significant compared to the feedback they receive through other communication channels. Figure 2 shows the percentage of the interaction of the five hospital TikTok accounts with the highest number of likes for videos published with healthcare content related to improving the quality of life and well-being of patients, avoiding pathologies or reducing their side effects: prevention and healthcare promotion. For Health Ministries, it should be pointed out that in the three selected accounts, prevention is the predominant content. The Spanish Ministry of Health only broadcasts one video with an image and voice-over; despite its exceptional activity, it does have an outstanding rate of interaction (33.85% of the followers of the @ministeriodesanidad account on TikTok liked-as of 30 September 2021-the video broadcast in 2020).
Regarding the analysis of the profiles selected after the search by hashtags, it should be noted that 100% of the accounts analysed, both those selected in a first filter and those of their followers, correspond to videos of young and adolescent females from 13 years of age (as identified in the network).
Although there are accounts and hashtags-such as #proana, #ana, #anorexia, #thinspiration, etc.-that the social media platform itself blocks and links to platforms that help patients and families, as well as offering guidelines to follow and "help materials" for recovery from this type of disorder, other similar terms related to eating disorders are very popular, and the algorithms used on the social media platform identify them as suitable for dissemination.
As mentioned above, in the classification, we divided the profiles found into groups according to whether or not they are people with an ED who recognise their disorder but who are not in the recovery phase (ED: 47.5%); people in recovery from a diagnosed eating disorder or who identify themselves as such (ED Recovery: 40%) and people who in this article are called "guides" and who are those who offer advice, recommendations, warnings or indications about how to act, generally taking on the role of specialists in the field Testimonies are also frequent either from professionals or from patients and relatives, as well as information about the hospital itself and health information. Despite the fact that the hospitals under analysis are privately managed and administered, only one video from one of the accounts shows a product for sale. On the other hand, although only two hospitals use social media to recruit professionals, this communication action is significant due to its exceptional nature.
For Health Ministries, it should be pointed out that in the three selected accounts, prevention is the predominant content. The Spanish Ministry of Health only broadcasts one video with an image and voice-over; despite its exceptional activity, it does have an outstanding rate of interaction (33.85% of the followers of the @ministeriodesanidad account on TikTok liked-as of 30 September 2021-the video broadcast in 2020).

As mentioned above, in the classification, we divided the profiles found into groups according to whether or not they are people with an ED who recognise their disorder but who are not in the recovery phase (ED: 47.5%); people in recovery from a diagnosed eating disorder or who identify themselves as such (ED Recovery: 40%) and people who in this article are called "guides" and who are those who offer advice, recommendations, warnings or indications about how to act, generally taking on the role of specialists in the field ("guides": 12.5%).
Of the 40 accounts chosen in a first analysis, more than half (27,67.5%) correspond to influencer profiles with more than 100,000 followers (Table 2), with the profiles of @clau-diap_psicologia and @victoriagarrick4 standing out with nearly 11 million and 59 million likes, respectively. Both belong to the "Guide" type (C) according to the classification despite this being the least represented group overall.  If we look at the emotions expressed according to the categories "happiness", "neutral", "fear", "disgust", "anger", "contempt" and "sadness" established by Maliguetti et al. [34], according to the analysis of images, the results are not conclusive. Some 17.5% of the accounts only show videos of the abdomen without faces either dancing or posing, so these profiles would be classified in the "neutral" category or would not be classified at all. As far as the "happiness" category is concerned, 37.5% of the profiles broadcast moments of happiness. However, it is difficult to determine whether these instances-seconds in which the videos are broadcasted-last over time. Nevertheless, it is notable that in 45% of the cases analysed, negative emotions of sadness, disgust, contempt, fear or anger are expressed towards the same person shown in the publication, as the image is accompanied by text-comments or terms-in this sense. Most of the videos in which these types of feelings are shared appear poorly lit or with black and white images with texts about calories consumed or pejorative terms.
In 120 profiles of selected followers, empathy with the tiktoker is the predominant manifestation ( Table 3) with messages of encouragement and positive reinforcement standing out in 21.67% of cases; of positive identification (about the achievements made in the face of an eating disorder), 14.17%; of negative identification (revealing being in the same situation of despair, depression, incomprehension, etc.), 39.17%; as well as messages of encouragement and positive identification (revealing being in the same situation of despair, depression, incomprehension, etc), 39.17%; as well as consultations for weight loss and advice for weight loss, 25%. Some of the accounts selected, two in the cases analysed, are "secret accounts", as these are called, and create a more closed community in which messages of identification predominate.
Among the messages in which they share negative feelings, those in which they directly ask for help to overcome a mental disorder stand out, as well as those in which they offer advice that threatens their health, such as actions that encourage vomiting, weight loss or disguising their deteriorating physical condition in front of others.

The publication of written or audiovisual testimonies does not infringe on the privacy of minors, firstly, because the messages analysed are public, and the domains of the selected tiktokers refer to profiles not individuals. The limitations of this study are related to the enormous number of messages that proliferate on social media about the cult of image and the care of physical and psychological state, which can be confused with those that contain harmful content or that could harm those who suffer from an eating disorder.

In this way, specialised healthcare institutions can play a fundamental role in terms of hospital communication through one of the social media platforms that has grown the most in recent years and has provoked the most interaction among one of the populations most affected by mental disorders. Planning and specialisation when developing health promotion and prevention content via TikTok could change the perception that many adolescents and young women have of their bodies and the way they take care of them, which leads to behaviour that is harmful to themselves, and at the same time, so can greater control of the accounts that incite this type of action, as well as a greater definition of the algorithms that promote their traffic on the network. Without questioning the professionalism of those who have been called "guides" in this study, it will be necessary to pay attention to those who issued judgments or advice masking unhealthy lifestyles with positive messages from idealized figures. It is considered vital that society in general and specialised care centres in particular become more aware of the existence and increasing number of people with EDs as a mental health disorder. The potential of social media platforms, such as TikTok, and their capacity to influence precisely the portion of the public most affected by or vulnerable to eating disorders is a reason for communication strategies aimed at the prevention of these disorders to be drawn up. The importance of this activity being supervised or directed by health and communication specialists who validate the quality of the content of the messages is fundamental in order to give the videos well-founded credibility.

From the results obtained, firstly, there is a notable lack of hospital accounts on TikTok, particularly in the case of Spain where none were found to the date of this study, although there are health-related profiles of healthcare professionals or those who identify themselves as such at an individual level. Despite this, most of the specialised healthcare entities that have been analysed at an international level obtain high performance in terms of the number of followers, likes, number of videos published and engagement, with health content related to prevention and health promotion being the predominant one.
On the other hand, the scientific literature has contrasted the increase in the use of the social media platform TikTok since its creation, especially among the young population. At the same time, this public group has been identified as the group most affected by the increase in mental health pathologies during the years of the COVID-19 pandemic.
According to the research, eating disorders, one of the most prevalent mental disorders among women, adolescents and young people, have found the "micro-videos" that are disseminated on social media platforms such as TikTok to be a favourable environment for their propagation. Although social media itself blocks access to certain content related to EDs, it is easy to find and interact with profiles that either promote this type of disorder (which could lead to self-harm or encouragement to suicide) or explicitly reject it. In most cases, this set of profiles becomes influencers, promoters of behaviour. The empathy generated by tiktokers can lead to the creation of communities that feed off each other mainly through their identification and encouragement of negative feelings (rejection of their own body, depression, anger, anguish, etc.) and, to a lesser extent, through their positive reinforcement.
In addition to these groups, there are profiles in which someone who is not identified as a specialist in the field advises and "guides" possible patients diagnosed with EDs or people at risk of suffering from an ED. These types of messages are confused among the huge amount of videos on image worship and supposedly healthy lifestyles.
Finally, thanks to the characteristics of social networks as communication channels and the possibility of collecting data from the interlocutors who participate in them, health institutions can obtain valuable information from their users, which they can use to improve the healthcare provided to citizens. For all of the above reasons, we consider it essential to encourage research into health communication via social networks, such as TikTok, due to the specific characteristics described above and, in particular, on eating disorders due to their prevalence and consequences among certain social groups.
