@article{Rösler_Gasparatos_Hermanussen_Scheffler_2022, title={Practicability and user-friendliness of height measurements by proof of concept APP using Augmented Reality, in 22 healthy children}, volume={2}, url={https://human-biology-and-public-health.org/index.php/hbph/article/view/48}, DOI={10.52905/hbph2022.2.48}, abstractNote={<p><strong>Background:</strong> Child growth is a dynamic process. When measured at short intervals, children’s growth shows characteristic patterns that can be of great importance for clinical purposes.</p> <p><strong>Objective:</strong> To study whether measuring height on a daily basis using an APP is practicable and user-friendly.</p> <p><strong>Methods:</strong> Recruitment took place via Snowball Sampling. Thirteen out of 14 contacted families signed up for a study period of 12 weeks with altogether 22 healthy children aged 3 to 13 years (response rate 93%). The study started with a visit to the family home for the setup of the measurement site, conventional height measuring and initial training of the new measurement process. Follow-up appointments were made at four, eight and 12 weeks. The children’s height was measured at daily intervals at their family homes over a period of three months.</p> <p><strong>Results:</strong> The parents altogether recorded 1704 height measurements and meticulously documented practicability and problems when using the device.</p> <p>A 93% response rate in recruitment was achieved by maintaining a high motivation within the families. Contact with the principal investigator was permanently available, including open communication, personal training and attendance during the appointments at the family homes.</p> <p><strong>Conclusion:</strong> Measuring height by photographic display is interesting for children and parents and can be used for height measurements at home. A positive response rate of 13 out of 14 families with altogether 22 children highlights feasible recruitment and the high convenience and user-friendliness of daily APP-supported height measurements. Daily APP measurements appear to be a promising new tool for longitudinal growth studies.</p>}, journal={Human Biology and Public Health}, author={Rösler, Antonia and Gasparatos, Nikolaos and Hermanussen, Michael and Scheffler, Christiane}, year={2022}, month={Dec.} }
