Out of the Mainstream: Low-Income, Lone Mothers’ Life Experiences and Perspectives on Heart Health
Bibliographic record
Abstract
Cardiovascular disease remains a health issue in North America, particularly for marginalized citizens. Although lifestyle issues and behavioral risk reduction continue to dominate prevention initiatives, an emerging literature suggests that contextual factors such as poverty and social exclusion also influence health. Using group and personal interviews (N = 38), this research explored the social and economic contexts shaping heart health-related experiences from the perspectives of low-income, lone mothers. The transcripts were analyzed using McKinlay and Marceau's upstream-midstream-downstream framework. The overriding pattern characterizing lone mothers' discussions was that the women felt out of the mainstream of everyday life. They lacked the resources and power to effect change, particularly regarding heart health behaviors that were not perceived to be a priority compared to more pressing survival issues. Results are discussed in terms of concepts from the population health and social determinants literature, concluding with policy implications for enhancing health while living in poverty.

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.
