Teen health app loses momentum when summer camp ends, pilot finds

A small Louisiana pilot found that an app, Fitbit trackers and personalised support helped teenagers stay active during a structured summer camp, but engagement fell sharply once it ended.

Summer holidays can make it harder for teenagers to keep regular routines, and a pilot study from Louisiana suggests that technology may help bridge that gap, at least for a while. Researchers from Pennington Biomedical Research Centre, FMOL Health | Our Lady of the Lake Children’s Health and Louisiana State University tested a programme that paired an in-person camp with a mobile app, Fitbit activity trackers and personalised support designed to encourage healthier behaviour in adolescents.

The study, published in Frontiers in Physiology, followed 25 young people aged 11 to 14. One group joined a 10-day summer camp that was followed by six weeks of technology-based support, while a comparison group took part in a virtual coding programme. During the camp, participants in the intervention group averaged 121 minutes a day of moderate-to-vigorous physical activity, a level of movement that met and exceeded common youth health targets, according to the researchers.

The programme centred on ProudMe Tech, an app that included an AI-assisted chatbot and behaviour-tracking features, alongside wearable devices and parent involvement after the camp ended. Researchers reported 851 app entries over the eight-week pilot, suggesting that the tools were usable within the highly structured camp setting. The team also said the hybrid format appeared to be acceptable to families, although the study was small and designed as a feasibility test rather than a definitive proof that the model prevents obesity.

Where the intervention struggled was after the camp finished. Engagement with the app fell during the six-week follow-up period, underscoring a familiar problem in digital health: it is often easier to maintain participation when young people are supported by face-to-face activities, routine and peer contact. Amanda Staiano of Pennington Biomedical said the findings were useful for shaping future programmes because summer break removes the structure of the school day and can lead to more sedentary time and less consistent eating and activity patterns.

The authors say larger randomised trials will be needed before anyone can judge whether this kind of summer programme meaningfully affects obesity-related outcomes. Their broader conclusion is in line with earlier research suggesting that mobile technology can help adolescents self-monitor behaviour and stay connected to health goals, but that lasting gains often depend on stronger in-person support, longer programmes and more family involvement.
