Field Application of Digital Technologies for Health Assessment in the 10,000 Families Study

Abstract

Background: We field tested new-to-market portable, digital applications to assess hearing, pulmonary, and cognitive function to determine the feasibility of implementing these applications across a range of age groups in the pilot phase of the 10,000 Families Study (10KFS), a new Minnesota family-based prospective cohort study.Methods: We followed manufacturer recommended protocols for audiometry (SHOEBOX Inc), spirometry (NuvoAir), and the digital clock drawing test (dCDT; Digital Cognition Technologies Inc).Results: These digital devices were low cost and readily implemented in a 2.5-hour health fair visit with minimal training (2-3 hours) of study staff. To date, we have performed these measurements on 197 eligible 10KFS participants during an inperson clinic visit. A total of 37 children (age 4-17 years), 107 adults (18-64 years), and 53 seniors (≥65 years) were eligible to undergo hearing and pulmonary assessments. Children were less likely to successfully complete the hearing test (76%) compared with adults (86%) and seniors (89%). However, successful completion of the pulmonary assessment was high across all groups: 100% of children and seniors and 98% of adults. The dCDT was performed among those over the age of 40, and completion rates were 92% for those aged 41-64 and 94% for those ≥65 years.Conclusions: Our field testing indicates these digital applications are easy and cost-effective to implement in epidemiologic studies.Impact: Digital applications provide exciting opportunities to collect data in population studies. Issues related to data privacy, data access, and reproducibility of measurements need to be addressed before deploying digital applications in epidemiologic studies.See all articles in this CEBP Focus section, "Modernizing Population Science."

Trends in Population-Based Studies: Molecular and Digital Epidemiology (Review)

“…To conduct large multicenter epidemiological studies, digital technologies are actively used to facilitate the processes of work planning, data remote collection and entry control, as well as subsequent result presentation and reuse [43][44][45][46].…”

Modernizing Population Sciences in the Digital Age

“…New field tools also abound, with real-time measurement of environmental exposures leveraging the use of smartphone apps and Fitbits in the Nurses' Health Study 3 (NHS3; ref. 6), and the use of digital applications in the field to assess physical and cognitive function in the 10,000 Families Study (7). Real-time mobile tools are also being deployed for intervention studies, such as text-based dietary interventions among colorectal cancer survivors (8) and the use of wearables (e.g., Fitbit) to promote physical activity (9, 10).…”
