'I've learned a lot about myself this year': Young student women's perceptions of their cumulative use of digital fitness technologies across the Covid-19 pandemic.

Many young women turned to digital fitness technologies (DFT) to support their health and wellbeing during the covid-19 pandemic. The present study explores young student women's retrospective perceptions of their cumulative engagement with DFT, across periods of restriction and easing (March 2020-2021). Seventeen UK-based women (Age M = 20.29, SD = 1.72); Ethnicity White = 94.12% participated in one-on-one interviews using an adapted scroll-back technique. Data was analysed using narrative-informed reflexive thematic analysis. Three themes were developed: My lockdown #fitnesstransformation: DFT as information and inspiration, My unrealistic expectations: DFT as a source of comparison and concern and My new body positive and resilient self: DFT as a catalyst to self-development. Themes highlight how perceptions of DFT changed over time as a consequence of repeat engagement, sociocultural context and psychological meaning-making. Crucially, findings underscore the importance of examining the collective and cumulative effects of DFT engagement on health and wellbeing, both positive and negative.

'I'm a failure again, I can't do it': Attitudes towards, and experiences of, exercise participation in adults with class III obesity.

OBJECTIVES: Living within a larger body brings unique challenges to exercise participation, which are poorly understood. This qualitative study explored the attitudes towards, and experiences of, exercise participation in adults with class III obesity. DESIGN: Individual semi-structured qualitative interviews. METHODS: We recruited 30 adults with class III obesity (body mass index: 45.8 ± 8.6 kg/m2) from a specialist multidisciplinary weight management service. Participants took part in semi-structured interviews while participating in a 6-month home-based aerobic and resistance exercise intervention. Open-ended questions were used flexibly to explore their views and experiences of exercise, encompassing barriers, motives and perceived benefits. Transcripts were analysed using reflexive thematic analysis. RESULTS: Three themes were developed: (1) a web of barriers; (2) tailored exercise facilitates positive experiences; and (3) a desire to live a normal life. People with class III obesity perceived that they were unable to do exercise; a view that was attributed to perceived judgement, low physical function, pain during everyday activities and failed weight loss attempts. These complex physical and psychosocial barriers to exercise were described as contributing to exercise avoidance. High value was placed on tailored exercise that accommodates the unique needs of moving in a larger body. A desire to carry out everyday tasks underpinned motivations for exercise. CONCLUSIONS: Our findings suggest that multi-component obesity interventions should move away from generic exercise prescriptions designed to maximize energy expenditure, and instead move towards addressing the unique physical and psychosocial needs of people who have class III obesity with tailored person-centred and weight-neutral exercise prescriptions.

Digital Bodies: A controlled evaluation of a brief classroom-based intervention for reducing negative body image among adolescents in the digital age.

BACKGROUND: A growing body of research has linked social media use to negative body image. AIMS: The present research aimed to evaluate the efficacy of Digital Bodies, a brief classroom-based intervention that aims to improve adolescents' body image. METHODS: British adolescents (N = 290; Age M = 12.81; SD = 0.40; Range = 12-13; Female = 151) were cluster randomized to intervention or waiting list control groups. Measures of body satisfaction, appearance ideal internalization (thin and athletic ideal internalization) and self-objectification were completed at baseline (T1), 1-week post-intervention (T2) and 8-week follow-up (T3). RESULTS: Multi-level modelling showed adolescents in the intervention group reported improved body satisfaction at T2, in comparison to the control, and crucially this effect was sustained at T3. Additionally, girls reported less thin ideal internalization at T2 relative to the control, but this effect was not sustained at T3. No other intervention effects were found. CONCLUSIONS: Overall, the findings provide initial support for the efficacy of Digital Bodies as an intervention for improving adolescents' body satisfaction.

Detecting Mental Health Behaviors Using Mobile Interactions: Exploratory Study Focusing on Binge Eating.

BACKGROUND: Binge eating is a subjective loss of control while eating, which leads to the consumption of large amounts of food. It can cause significant emotional distress and is often accompanied by purging behaviors (eg, meal skipping, overexercising, or vomiting). OBJECTIVE: The aim of this study was to explore the potential of mobile sensing to detect indicators of binge-eating episodes, with a view toward informing the design of future context-aware mobile interventions. METHODS: This study was conducted in 2 stages. The first involved the development of the DeMMI (Detecting Mental health behaviors using Mobile Interactions) app. As part of this, we conducted a consultation session to explore whether the types of sensor data we were proposing to capture were useful and appropriate, as well as to gather feedback on some specific app features relating to self-reporting. The second stage involved conducting a 6-week period of data collection with 10 participants experiencing binge eating (logging both their mood and episodes of binge eating) and 10 comparison participants (logging only mood). An optional interview was conducted after the study, which discussed their experience using the app, and 8 participants (n=3, 38% binge eating and n=5, 63% comparisons) consented. RESULTS: The findings showed unique differences in the types of sensor data that were triangulated with the individuals' episodes (with nearby Bluetooth devices, screen and app use features, mobility features, and mood scores showing relevance). Participants had a largely positive opinion about the app, its unobtrusive role, and its ease of use. Interacting with the app increased participants' awareness of and reflection on their mood and phone usage patterns. Moreover, they expressed no privacy concerns as these were alleviated by the study information sheet. CONCLUSIONS: This study contributes a series of recommendations for future studies wishing to scale our approach and for the design of bespoke mobile interventions to support this population.

'When you think of exercising, you don't really want to think of puking, tears, and pain': Young adolescents' understanding of fitness and #fitspiration.

Adolescents access information about fitness, including content labelled as #fitspiration, through social media. A total of 77 adolescents (mean age = 12.49; standard deviation = 0.55; girls = 27) participated in semi-structured focus groups to explore their perspectives on #fitspiration and fitness more broadly. Through inductive thematic analysis, four themes were developed: (1) fitness enhances physical function and appearance, but these are not always linked; (2) fitness is transformative but requires hard work; (3) fitness should be an intrinsically motivated personal choice; and (4) pain in the pursuit of fitness. Findings highlight young adolescents' complex understandings of fitness negotiated through their critical interpretation of #fitspiration.

Body talk in the digital age: A controlled evaluation of a classroom-based intervention to reduce appearance commentary and improve body image.

This research evaluates the efficacy of a classroom-based intervention - Body Talk in the Digital Age (BTIDA) - in reducing adolescents' appearance commentary and improving body image. British adolescents (N = 314; Age Range = 12-14) were cluster randomised to intervention or waiting-list control groups. Measures of appearance commentary, appearance ideal internalisation, self-objectification and body satisfaction were completed at baseline (T1), then one-week (T2) and eight-week (T3) post-intervention. Multi-level modelling showed girls who received BTIDA reported less appearance commentary engagement and thin ideal internalisation at T2 and T3, than the control, supporting the partial efficacy of BTIDA for girls. No intervention effects were found among boys.

Understanding the Role of Healthy Eating and Fitness Mobile Apps in the Formation of Maladaptive Eating and Exercise Behaviors in Young People.

BACKGROUND: Healthy eating and fitness mobile apps are designed to promote healthier living. However, for young people, body dissatisfaction is commonplace, and these types of apps can become a source of maladaptive eating and exercise behaviors. Furthermore, such apps are designed to promote continuous engagement, potentially fostering compulsive behaviors. OBJECTIVE: The aim of this study was to identify potential risks around healthy eating and fitness app use and negative experience and behavior formation among young people and to inform the understanding around how current commercial healthy eating and fitness apps on the market may, or may not, be exasperating such behaviors. METHODS: Our research was conducted in 2 phases. Through a survey (n=106) and 2 workshops (n=8), we gained an understanding of young people's perceptions of healthy eating and fitness apps and any potential harm that their use might have; we then explored these further through interviews with experts (n=3) in eating disorder and body image. Using insights drawn from this initial phase, we then explored the degree to which leading apps are preventing, or indeed contributing to, the formation of maladaptive eating and exercise behaviors. We conducted a review of the top 100 healthy eating and fitness apps on the Google Play Store to find out whether or not apps on the market have the potential to elicit maladaptive eating and exercise behaviors. RESULTS: Participants were aged between 18 and 25 years and had current or past experience of using healthy eating and fitness apps. Almost half of our survey participants indicated that they had experienced some form of negative experiences and behaviors through their app use. Our findings indicate a wide range of concerns around the wider impact of healthy eating and fitness apps on individuals at risk of maladaptive eating and exercise behavior, including (1) guilt formation because of the nature of persuasive models, (2) social isolation as a result of personal regimens around diet and fitness goals, (3) fear of receiving negative responses when targets are not achieved, and (4) feelings of being controlled by the app. The app review identified logging functionalities available across the apps that are used to promote the sustained use of the app. However, a significant number of these functionalities were seen to have the potential to cause negative experiences and behaviors. CONCLUSIONS: In this study, we offer a set of responsibility guidelines for future researchers, designers, and developers of digital technologies aiming to support healthy eating and fitness behaviors. Our study highlights the necessity for careful considerations around the design of apps that promote weight loss or body modification through fitness training, especially when they are used by young people who are vulnerable to the development of poor body image and maladaptive eating and exercise behaviors.

Selfie-Objectification: Self-Objectification and Positive Feedback ("Likes") are Associated with Frequency of Posting Sexually Objectifying Self-Images on Social Media.

The present study is the first to examine the extent to which young adult women post objectifying self-images on social media, and whether the frequency of posting such content can be predicted by self-objectification and positive feedback (likes). Eighty-six young adult women from the UK (Age M = 19.88; SD = 1.34, Range = 18-24) completed self-report measures of self-objectification and social media use. The 20 most recent images they had posted on their personal Instagram accounts were downloaded (Image N = 1720) and content analysed for self-objectifying content. The analysis found that 29.77% of participants' Instagram images were objectified, though there were individual differences. Higher frequency of posting objectified self-images was associated with trait self-objectification and receiving more likes on this type of self-image, relative to non-objectified self-images. The implications of the novel findings for objectification theory are discussed within.

The impact of thin models in music videos on adolescent girls' body dissatisfaction.

Music videos are a particularly influential, new form of mass media for adolescents, which include the depiction of scantily clad female models whose bodies epitomise the ultra-thin sociocultural ideal for young women. The present study is the first exposure experiment that examines the impact of thin models in music videos on the body dissatisfaction of 16-19-year-old adolescent girls (n=87). First, participants completed measures of positive and negative affect, body image, and self-esteem. Under the guise of a memory experiment, they then either watched three music videos, listened to three songs (from the videos), or learned a list of words. Affect and body image were assessed afterwards. In contrast to the music listening and word-learning conditions, girls who watched the music videos reported significantly elevated scores on an adaptation of the Body Image States Scale after exposure, indicating increased body dissatisfaction. Self-esteem was not found to be a significant moderator of this relationship. Implications and future research are discussed.
