Awareness of Omega-3 Fatty Acids and Possible Health Effects among Young Adults
Bibliographic record
Abstract
Purpose: To assess awareness of omega-3 fatty acids (FAs) and their possible health effects among young adults. Methods: An online survey was deployed to young adults. Questionnaire development involved identification of topic areas by content experts and adaptation of questions from previous consumer surveys. Focus groups and cognitive interviews ensured face validity, feasibility, and clarity of survey questions. Degrees of awareness and self-reported consumption were assessed by descriptive statistics and associations by Cochran’s Q tests, Pearson’s χ2tests, Z-tests, and logistic regression. Results: Of the 834 survey completers (aged 18–25 years), more respondents recognized the abbreviations EPA (∼51%) and DHA (∼66%) relative to ALA (∼40%; P ≤ 0.01). Most respondents (∼83%) recognized that EPA and DHA have been linked to heart and brain health. Respondents who used academic/reputable sources, healthcare professionals, and/or social media to obtain nutritional information were more likely to report awareness of these health effects (P ≤ 0.01). Finally, 48% of respondents reported purchasing or consuming omega-3 foods, while 21% reported taking omega-3 supplements. Conclusions: This baseline survey suggests a high level of awareness of some aspects of omega-3 fats and health in a sample of young adults, and social media has become a prominent source of nutrition and health information.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
