Objective: To investigate how dieting is portrayed on TikTok and the potential implications for public health considering the effect of diet culture on eating disorders amongst young people. Design: A cross-sectional descriptive content analysis of 250 videos from the five most popular diet-related hashtags. A codebook was developed to analyse the content of the videos and collect the engagement for each video (likes, comments and shares). Setting: TikTok website. Participants: There were no participants in this study. Results: More than half of the videos portrayed ‘body checking’, a potentially harmful practice for body image. Of the videos that represented body image, almost half represented body image negatively. However, most videos promoted the idea of ‘healthy eating’, and only 6·4 % displayed disordered eating behaviours. Over half of the videos provided dietary advice, and of those videos, most content creators claimed to be experts (64 %). Claiming expertise was not significantly associated with engagement; however, the use of humour was significantly associated with engagement. Additionally, males were more likely than females to disclose their goals of the diet. Conclusions: Overall, it appears that TikTok is commonly used to share nutrition tips and personal experiences around dieting and eating in general, often employing humour as an effective technique. The popularity of the platform and rapid dissemination of information would be a useful tool for health professionals, especially those working with eating disorders, to utilise.

Despite the medical and surgical improvements of paediatric burn injuries, burn injuries can be a painful and traumatic experience for the child and their family. It is therefore important to explore the experiences of caregivers who support their child throughout the burn journey. Thus, the purpose of this study was to explore the traumatic nature of paediatric burns on the family from a caregiver's perspective. This study used a descriptive qualitative approach to conduct online semi-structured interviews with caregivers (18 years and older) of children (aged four to 17 years) that had previously been admitted with an unintentional acute burn injury to a paediatric burns unit in Western Australia. Interviews explored the child's and caregiver's experiences throughout the burn journey from the perspective of the caregiver and were digitally recorded and transcribed verbatim. Transcripts were analysed using Braun and Clarke's six stages of reflexive thematic analysis. Eleven mothers participated in the interviews and identified a range of poor psychological and psychosocial outcomes that themselves and their child experienced. Three overarching themes were elaborated from the interviews: Child and caregiver mental health difficulties during and after the burn (including medical trauma, mental health outcomes and caregiver guilt); Lifestyle and physical changes following the burn (including disruptions to routine, appearance concerns and puberty); and factors supporting or inhibiting the recovery journey (including personality factors, coping strategies, family dynamics and support). This study has presented the difficulties that children, young people, and their family face throughout a paediatric burn injury, which makes the implementation of timely and effective family centred interventions imperative. Meeting the needs and supporting these families with their mental health throughout this traumatic recovery journey, can ensure positive psychosocial outcomes and adaptive coping strategies are adopted early on.

The social media application TikTok allows users to view and upload short-form videos. Recent evidence suggests it has significant potential for both industry and health promoters to influence public health behaviours. This protocol describes a standardised, replicable process for investigations that can be tailored to various areas of research interest, allowing comparison of content and features across public health topics. The first 50 appearing videos in each of five relevant hashtags are sampled for analysis. Utilising a codebook with detailed definitions, engagement metadata and content variables applicable to any content area is captured, including an assessment of the video’s overall sentiment (positive, negative, neutral). Additional specific coding variables can be developed to provide targeted information about videos posted within selected hashtags. A descriptive, cross-sectional content analysis is applied to the generic and specific data collected for a research topic area. This flexible protocol can be replicated for any health-related topic and may have a wider application on other platforms or to assess changes in content and sentiment over time. This protocol was developed by a collaborative team of child health and development researchers for application to a series of topics. Findings will be used to inform health promotion messaging and counter-advertising.

Background Food marketing exposure has the potential to influence children’s dietary behaviours and health status, however, few studies have identified how ‘obesogenic’ the outdoor food marketing environment is along public transport (bus and/or train) or walking routes that children take to school. Methods Audits of all outdoor advertisements present along likely train, bus and walking routes to 24 secondary schools (ie, 3 routes per school, 72 routes total) were conducted in Perth, Western Australia (WA). The size, content, type and setting of each advertisement were recorded in accordance with the International Network for Food and Obesity/non-communicable diseases Research, Monitoring and Action Support protocol for monitoring outdoor advertising. Results Of the 4016 total advertisements observed, almost half were for food (n=1754, 44%) and of these, 80% (n=1397) advertised discretionary (non-core) foods, and 8% (n=138) advertised healthy (core) foods. On average, commuting to school by train, bus and walking exposed Perth schoolchildren to 37.1, 22 and 4.5 discretionary (non-core) food ads per one-way trip to school, respectively. Conclusions Children living in Perth, WA experience a high level of exposure to unhealthy outdoor food advertisements during the school commute. Policies which restrict the placement and content of outdoor advertising, could be a useful strategy in the fight against childhood obesity.

Background: Experiencing a traumatic event can significantly impact mental and emotional well-being. Social media platforms offer spaces for sharing stories, seeking support, and accessing psychoeducation. TikTok (ByteDance), a rapidly growing social media platform, is increasingly used for advice, validation, and information, although the content of this requires further study. Research is particularly needed to better understand TikTok content relating to trauma and the potential implications for young viewers, considering the distressing nature of the subject and the possibility of users experiencing vicarious trauma through exposure to these videos. Objective: This study aims to explore the content of trauma-related videos on TikTok, focusing on hashtags related to trauma. Specifically, this study analyzes how TikTok videos present information, advice, stories, and support relating to trauma. Methods: A quantitative cross-sectional descriptive content analysis was performed on TikTok in December 2022. A total of 5 hashtags related to trauma were selected: #trauma, #traumatized, #traumatok, #traumatic, and #traumabond, with the top 50 videos from each hashtag analyzed (total N=250 videos). A standardized codebook was developed inductively to analyze the content of the videos, while an existing generic codebook was used to collect the video features (eg, age of people in the video) and metadata (likes, comments, and shares) for each video. Results: A total of 2 major content themes were identified, which were instructional videos (54/250, 21.6%) and videos disclosing personal stories (168/250, 67.3%). The videos garnered significant engagement, with a total of 296.6 million likes, 2.3 million comments, and 4.6 million shares, indicating that users find this content engaging and useful. Alarmingly, only 3.7% (9/250) of videos included a trigger warning, despite many featuring highly distressing stories that young people and those with trauma may be exposed to. Conclusions: The study highlights the potential risks of vicarious trauma due to trauma dumping without trigger warnings on TikTok, and the need for further research to assess the accuracy of advice and information in these videos. However, it also underscores the platform’s potential to foster social connections, provide validation, and reduce stigma around mental health issues. Public health professionals should leverage social media to disseminate accurate mental health information, while promoting user education and content moderation to mitigate potential harms. People often use social media, such as TikTok to share advice, stories, and support around mental health, including their experiences with trauma. Out of 250 videos, most were either giving advice (54/250, 21.6%) or sharing personal experiences (168/250, 67.3%). The study found many videos lacked warnings about upsetting content, which could potentially harm young viewers or people suffering from trauma. While TikTok can help people feel connected and reduce the stigma around mental health, it is important to seek support from professionals when needed.
