INDDEX24 Dietary Assessment Platform

  1. 1. INDDEX24 Dietary Assessment Platform Winnie Bell Senior Technical Advisor, Intake Center for Dietary Assessment FHI Solutions 28 July 2022
  2. 2. Traditional pen-and paper 24-hour dietary recalls • Time consuming, error prone, expensive • Limited investment in research infrastructure and dietary reference data o Comprehensive food lists o Food composition databases o Standard recipes o Conversion factors • Lack of centralized hub resulting in inefficiencies as each study “reinvents the wheel” • Cleaning and processing data is time intensive resulting in delayed policy and programmatic action
  3. 3. INDDEX Integrated Platform Developed by the INDDEX Project, Tufts University
  4. 4. Global Food Matters Database  Designed to enable sharing of dietary reference data among users to increase efficiencies for dietary surveys  Centralized, publicly accessible repository of dietary reference data (food list, recipes, conversion factors etc.)  Users can copy existing workspaces and/or download data to their computer in a formatted Excel template  Food, recipe, and ingredient names can be translated in up to four languages for a given workspace  Data are seamlessly linked to the INDDEX24 Mobile App, allowing for customization and easy updates to dietary reference data Developed by the INDDEX Project, Tufts University
  5. 5. INDDEX24 Mobile App  Quantitative multi-pass 24-hr dietary recall app that works on any Android device (e.g., tablet)  Interviewer administered and designed to work fully offline with data uploaded to cloud with WiFi connection  Can be used in up to four languages per survey  Allows data to be collected consistently across a survey through use of probes and standardardized approach  Customizable food and recipe list via linkage with the Global Food Matters Database Developed by the INDDEX Project, Tufts University

  7. 7. Benefits of Using INDDEX24 • Reduced total costs: INDDEX24 costs less than paper per respondent • Further cost/time savings: Leveraging existing dietary reference data in FMDB will save money and time • Lower respondent burden: Equal or lower average time per interview when using INDDEX24 compared to paper • Shorter survey cycle: Less total time required from survey preparation to policy • Data quality: Accuracy of results as good as or better than pen-and- paper data collection • Improved user experience: Enumerators and respondents overall preferred INDDEX24 To date INDDEX24 has been used in 10 studies in six countries in Sub-Saharan Africa and Southeast Asia
  8. 8. INDDEX24 Summary • INDDEX24 Dietary Assessment Platform is a multicomponent system designed to overcome key bottlenecks • INDDEX24 has been rigorously tested and adopted by a variety of users • The Global Food Matters Database can help increase efficiencies related to survey preparation and processing • Sign up for access to the Global Food Matters Database: https://inddex.nutrition.tufts.edu/global-food-matters • Contact us for more information about using INDDEX24: INDDEX24@FHISolutions.org

  14. 14. Becoming an INDDEX24 User ~ From preparation through data collection ~ 1) Set-up a Global FMDB workspace and begin preparing dietary reference data (Time: 1-6 months) 2) Set-up a CommCare project space and develop other modules for survey (Time: 1-2 months) 3) Prepare the INDDEX24 mobile app for the field (e.g., context specific modifications, translations etc.) (Time: 1-2 months) 4) Field test INDDEX24 and the food list, recipes, probes, and conversion methods (Time: 1-2 weeks) 5) Make any necessary revisions or additions to the food list and other dietary reference data (Time: 1-2 weeks) 6) Train supervisors and enumerators on how to use INDDEX24 (Time: 1-3 weeks) 7) Data collection (Time: Varies based on survey and context) 8) Monitor data as it is collected and make updates to food list and dietary reference data through FMDB as needed 9) After data collection, use Analytical Reports to produce data that has been converted and matched to FCT, with preliminary analysis
