A new web app that connects children’s daily activities and health

Researchers studying how children’s daily activities are related to their health have shown how redistributing their day’s time from one activity to another affects their health and academic performance. I developed a web app that shows users what The new app and the data used to develop it are described in a paper published this week in an open access journal. pro swan By Dorothea Dumuid and colleagues at the University of South Australia.

How we use our time can affect our health, well-being and productivity, but the relationship between how we use our time and outcomes can be difficult to interpret for both medical professionals and the general public.

In the new study, researchers used data from 1,685 children aged 11 to 12 enrolled in the Australian Child Health Checkpoint Study. Time spent in daily activities was derived from a self-reported 24-hour recall tool that reminds children of the activities they performed the previous day to her 5-minute granularity. Data were also available on each participant’s body fat percentage, psychosocial health, and academic performance. After adjusting for age, socioeconomics, and adolescent status, they found that people’s use of time correlated with body fat percentage (F=2.66, p<0.001) and psychosocial health (F=4.02, p<0.001). , and was significantly associated with academic achievement. (F=2.76, p<0.001).

To convey the strength of these associations in a comprehensible and interactive way, the authors developed a Healthy-Day-App that allows users to enter their initial time allotment and display how their time use changes. I have developed a web app called associated with the result. For example, redistributing her 60 minutes from screen time to physical activity reduces her body fat by 4.2% on average (-0.8). [95% CI -1.0 to -0.5] in percentage), 2.5% improvement in psychosocial health (+1.9 [1.4 to 2.5] PedsQL Psychosocial Health Score) and 0.9% higher academic performance (+4.5 [1.8 to 7.2] NAPLAN writing score). However, benefits may diminish when physical activity time is redistributed from other activities.

The authors state that the Healthy-Day-App is the first to allow customized estimation of the impact of time allocation, and will be used not only by researchers, but also by public health advocates, healthcare professionals, and fitness practitioners. It has the potential to enable better engagement and understanding of data. Professionals, policy makers, and the general public.

The author adds: “Sleep, exercise, screen time, homework – there are only 24 hours in a day, so there are many competing demands on children’s time. We can compare how the use of OFF is estimated to affect the health and well-being of children.”
