The Association Between Age and Household Food Insecurity in Canada
Bibliographic record
Abstract
While there have been several studies documenting the lower risk of food insecurity among seniors, little is known about how food insecurity relates to age among Canadians under 65. This thesis aimed to i) determine how food insecurity varies by age group; and ii) characterize the association between sociodemographic characteristics and food insecurity among adolescents. Using data from the 2017-18 Canadian Community Health Survey, logistic regression analyses were conducted, adjusting for sociodemographic characteristics. Adolescents and middle-aged adults had higher odds of food insecurity than 55- to 64-year-olds, whereas seniors had lower odds. Income, homeownership and living arrangement were differently associated with food insecurity. Among adolescents, lower household income, renting, social assistance receipt, Black and Indigenous identity, single parenthood and more children were associated with moderate-severe food insecurity. Given the negative health implications of food insecurity, the elevated risk among adolescents indicates the need for policies that better protect them.

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.
