Abstract

fetched live from OpenAlex

OBJECTIVE: A school environment that encourages students to opt for food with sound nutritional value is both essential and formative in ensuring that young people adopt healthy eating habits. The present study explored the associations between the socio-economic characteristics of the school environment and the school food environment. DESIGN: A cross-sectional survey was conducted in 2008-2009. Descriptive and bivariate analyses were performed on data from public primary and secondary schools. SETTING: Quebec, Canada. The school food offering was observed directly and systematically by trained research assistants. Interviews were conducted to fully describe food offerings in the schools and schools' child-care services. SUBJECTS: A two-stage stratified sampling was used to build a representative sample of 143 French-speaking public schools. The response rate was 66.2%. RESULTS: The primary and secondary schools in low-density areas were more likely to be located near diners (primary: P=0.018; secondary: P=0.007). The secondary schools in deprived areas were less likely to have a regular food committee (P=0.004), to seek student input on menu choices (P=0.001) or to have a long lunch period (P=0.010). The primary schools in deprived areas were less likely to have a food service (P=0.025) and their meal periods were shorter (P=0.033). CONCLUSIONS: The schools in areas with lower socio-economic status provided an environment less favourable for a healthy diet. From a public health perspective, the results of this analysis could assist policy makers and managers to identify actions to support the creation of favourable school environments.

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.
