Abstract
This study examines how child, maternal, family, and health-related determinants contribute to variations in the uptake of paid maternal leave. We used data from the Quebec Longitudinal Study of Child Development, a representative cohort of infants born in 2020–2021 (N = 3456). Mothers were interviewed at 5 and 17 months postpartum, and three groups of leave were derived: no leave taking (n = 299), maternity leave with non-shared weeks of parental leave (n = 1927), and maternity leave with shared weeks of parental leave (n = 1150). Multivariate multinomial regression models using survey-weighted data yielded odds ratios. Low educational attainment, immigration background, poverty, cannabis use, and perinatal preventive services usage increased the odds of taking no leave, while being a first-time mother and a single parent, drinking alcohol during pregnancy, and accessing preventive withdrawal were associated with a decreased likelihood of not taking leave. Maternal age, lower educational attainment, and poverty were associated with increased odds, while immigration background and cannabis use were associated with decreased odds of taking maternity leave with non-shared (vs. shared) parental benefits. Mothers with no leave taking are more likely to experience increased socioeconomic hardship. Citizenship-based rather than employment-based parental leave policy could promote early-life equity across families from diverse backgrounds.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
