Abstract

fetched live from OpenAlex

PURPOSE: This study describes trajectories of food bank (FB) use among new users in relation with change in food insecurity status. METHODS: The Pathways Study followed 1001 new FB users across four regions of Québec, Canada, over a two-year period, from September 2018 to January 2020. Participants reported past-month FB use in two consecutive interviews following a baseline assessment, leading to 24 consecutive measures of monthly FB use. Household food insecurity was measured using the Household Food Security Survey Module. Group-based trajectory analysis was used to identify trajectories of FB use. RESULTS: Six trajectories were identified, including chronic use (30 % of the sample), infrequent use (11 %), withdrawal after recruitment (22 %), fast withdrawal (14 %), slow withdrawal (15 %), and intermittent (8 %). Chronic FB usage was associated with lower education levels and rural residency, suggesting economic challenges and limited opportunities in such areas. About a third of FB users changed their status from food insecure at baseline to food secure at the end of follow-up. CONCLUSIONS: These findings challenge the perception of FB users as a homogenous group and emphasize the need for tailored approaches to address food insecurity.

Not 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.
