Pilot Study on The Nutritional Assessment and Intervention Kiosk: Utility and User-Centric Performance Evaluation in Combating Malnutrition

Abstract

Background: To combat double burden of malnutrition, Nutritional Assessment and Intervention Kiosk (NAIK) has been proposed as a potential solution. which provides personalized nutritional assessments and interventions, leveraging the latest digital health technologies. The present pilot study reports user-centric performance evaluation and utility of NAIK to determine its impact on managing malnutrition.

Methodology: The 406 samples were purposively selected to include children aged 2–5 years and their mothers living in urban slum areas of Gautam Budh Nagar District of Uttar Pradesh through the online-based NAIK. In order to evaluate the users' ability to utilize the developed system, the participants were tasked with completing a series of assigned usability tasks. The user-centric performance evaluation of the system was also evaluated.

Results: Out of total 406 sample, till the third visit 123 subjects (30.29%) were retained. A significant majority of respondents found NAIK platform easy to use but most users did feel the need for professional assistance. Overall, the assessments reveal that the NAIK platform is well-received by users. However, minor improvements could enhance clarity and reduce the learning curve for new users.

Conclusions: The positive user feedback on the usability of NAIK further supports its potential as a valuable tool for nutritional interventions in low-resource settings.
