Abstract
This article provides recent estimates of the duration and quality of sleep of Canadian adults and of the percentage who adhere to sleep duration guidelines (7 to 9 hours per night at ages 18 to 64, and 7 to 8 hours per night at age 65 or older). The study is based on 10,976 respondents aged 18 to 79 from the 2007-to-2013 Canadian Health Measures Survey, a nationally representative, cross-sectional survey. Sleep duration and quality were self-reported. Mean sleep duration was 7.12 hours per night at ages 18 to 64 and 7.24 hours per night at ages 65 to 79. An estimated 65% of 18- to 64-year-olds and 54% of seniors slept the recommended number of hours per night. However, short sleep duration and poor sleep quality were relatively common. About a third slept fewer hours than recommended. At ages 18 to 64, an estimated 43% of men and 55% of women reported trouble going to sleep or staying asleep "sometimes/most of the time/all of the time"; the corresponding percentages at ages 65 to 79 were 40% and 59%.

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
