Resource Profile: AT PreNUDGE Observation Nutrition Sugar Salty Frequency

Records self-reported consumption frequency of sugary, fatty, and salty foods and energy-dense drinks, based on ATHIS 2025 question DH6. Coded using SNOMED CT 364395008 'Dietary intake (observable entity)' as the observation concept; update if a more specific LOINC code is identified for this measurement.

Usages:

• Examples for this Profile: Observation/nutrition-sugarsalty-daily-example, Observation/nutrition-sugarsalty-not-stated-example and Observation/nutrition-sugarsalty-rare-example
