Understanding Australian adolescent girls’ use of digital technologies for healthy lifestyle purposes: a mixed-methods study

Abstract

Background Little is known about girls’ use of a broad range of digital technologies to support a healthy lifestyle, particularly during the later adolescent years when they are expected to take greater responsibility for individually managing their health and wellbeing. The present study was designed to gain an in-depth understanding of adolescent girls’, 15 to 17 years of age, use of a broad range of digital technologies to support multiple healthy lifestyle purposes. Methods This study used a mixed-methods sequential research design (i.e. quantitative and qualitative data in two consecutive phases). A quantitative online survey was conducted to determine the use of digital technologies for healthy lifestyle purposes. Qualitative semi-structured interviews were conducted with a subset of survey respondents to explore factors influencing their technology use and preferences. Results Descriptive analysis of survey data (online survey, n = 336) demonstrated the popularity of social media and online video sharing platforms, with evidence that the use of digital technologies does not occur in isolation and girls draw on several resources simultaneously to achieve their desired healthy lifestyle outcomes. Thematic analysis of interview data (semi-structured interviews, n = 29) revealed seven interrelated themes around factors influencing girls’ use of, and satisfaction with, different digital technologies: accessibility, social connectivity, credibility, relatability, inspiration, safety, and customisability. Conclusions The findings reiterate that one size doesn’t fit all girls, and often one size might not even fit one girl, and thus highlight the challenge of catering to such varied use cases. Overall, it appears that current digital technology offerings meet the needs and preferences of adolescent girls for healthy lifestyle purposes, however there may be benefit in allowing greater customisation of use, and consumer driven tailoring of content, according to personal preferences and changing circumstances.

‘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

“…Participants described using different elements of DFT for different reasons at different times across the pandemic, with varying levels of intensity and consistency. While consistent long-term use is often the aim of DFT providers, as evidenced in this study and others, consistent use of specific content, products or services over time is rare (Honary et al, 2019;Parker et al, 2022). Participants cited multiple intersecting reasons for disengaging with DFT -both in general and from specific types -including feeling bad about oneself and one's body because of their DFT use, goals being met (e.g.…”

“…The social ecology theory also suggests that digital technologies located in the exosystem is a proximal factor influencing health behaviors of young people [ 12 ]. Digital technologies such as smartphone applications and mass media constitute a context for the daily interaction of adolescents that can promote both health-compromising and health-enhancing behaviors [ 17 ]. In HPM, Pender emphasizes that the use of technological advances is effective to achieve healthy life behaviors and positive health outcomes [ 18 ].…”

A New Materialist Analysis of Health and Fitness Social Media, Gender and Body Disaffection: ‘You Shouldn’t Compare Yourself to Anyone… but Everyone Does’

“…Digital technologies, particularly social media, are now recognised as having pedagogical capacities [2], with a growing body of work examining how young people now learn about their health through these networking platforms, particularly those that are image based [3][4][5][6][7]. Furthermore, studies are beginning to reveal the ways in which these platforms may be contributing to the growth of body imagerelated conditions [8][9][10]. These body concerns have worsened following the effects of COVID-19 lockdowns and the intensification of social media and fitness app usage during that time [10].…”
