Digital citizen science for ethical surveillance of physical activity among youth: mobile ecological momentary assessments vs. retrospective recall
Physical inactivity is the fourth leading risk factor of mortality globally.
Hence, understanding the physical activity (PA) patterns of youth is essential
to manage and mitigate non-communicable diseases. As digital citizen science
approaches utilizing citizen-owned smartphones to ethically obtain PA big data
can transform PA surveillance, this study aims to understand the frequency of
PA reported by youth using smartphone-deployed retrospective validated surveys
compared to prospective time-triggered mobile ecological momentary assessments
(mEMAs). Using a digital citizen science methodology, this study recruited
youth citizen scientists (N = 808) in 2018 (August 31- December 31) in
Saskatchewan, Canada. Youth citizen scientists (age 13 to 21) reported their PA
using prospective mEMAs and retrospective surveys over an eight-day period. A
significant difference was found in reporting the frequency of PA
retrospectively vs. prospectively via mEMAs (p < 0.000). Ethnicity, parental
education, and strength training were associated with prospective PA frequency;
however, no associations were significant with retrospective PA frequency. With
access to ubiquitous digital devices growing worldwide, and youth having
particularly high digital literacy, digital citizen science for the ethical
surveillance of PA using mEMAs presents a promising approach for the management
and prevention of non-communicable diseases among youth

The role of physical activity (PA) in minimizing non-communicable diseases is well established. Measurement bias can be reduced via ecological momentary assessments (EMAs) deployed via citizen-owned smartphones. This study aims to engage citizen scientists to understand how PA reported digitally by retrospective and prospective measures varies within the same cohort. This study used the digital citizen science approach to collaborate with citizen scientists, aged 13–21 years over eight consecutive days via a custom-built app. Citizen scientists were recruited through schools in Regina, Saskatchewan, Canada in 2018 (August 31—December 31). Retrospective PA was assessed through a survey, which was adapted from three validated PA surveys to suit smartphone-based data collection, and prospective PA was assessed through time-triggered EMAs deployed consecutively every day, from day 1 to day 8, including weekdays and weekends. Data analyses included paired t-tests to understand the difference in PA reported retrospectively and prospectively, and linear regressions to assess contextual and demographic factors associated with PA reported retrospectively and prospectively. Findings showed a significant difference between PA reported retrospectively and prospectively (p = 0.001). Ethnicity (visible minorities: β = - 0.911, 95% C.I. = -1.677, -0.146), parental education (university: β = 0.978, 95% C.I. = 0.308, 1.649), and strength training (at least one day: β = 0.932, 95% C.I. = 0.108, 1.755) were associated with PA reported prospectively. In contrast, the number of active friends (at least one friend: β = 0.741, 95% C.I. = 0.026, 1.458) was associated with retrospective PA. Physical inactivity is the fourth leading cause of mortality globally, which requires accurate monitoring to inform population health interventions. In this digital age, where ubiquitous devices provide real-time engagement capabilities, digital citizen science can transform how we measure behaviours using citizen-owned ubiquitous digital tools to support prevention and treatment of non-communicable diseases.</div
