Abstract
BACKGROUND: Osteoporosis is a bone disease that predisposes to fractures. Sufficient intake of calcium and vitamin D is recommended for prevention and treatment. DATA AND METHODS: Based on 28,406 respondents aged 50 or older to the 2009 Canadian Community Health Survey (CCHS)--Healthy Aging, the population who reported being diagnosed with osteoporosis is profiled. Analysis of calcium and vitamin D intake is based on 10,879 respondents aged 50 or older to the 2004 CCHS--Nutrition. Frequencies, averages and cross-tabulations were produced to estimate the prevalence of diagnosed osteoporosis, dietary intake of calcium and vitamin D, the use of supplements, and total calcium and vitamin D intake. Associations between a diagnosis of osteoporosis and socio-economic, dietary and lifestyle factors were examined with multiple logistic regression. RESULTS: In 2009, 19.2% of women and 3.4% of men aged 50 or older reported having been diagnosed with osteoporosis; the 2004 rates were similar. Age, sex and household income were associated with the probability of reporting osteoporosis. In 2004, based on dietary and supplement intake, 45% to 69% of the population aged 50 or older had inadequate intake of calcium, and 54% to 66% had inadequate intake of vitamin D. INTERPRETATION: A large percentage of people aged 50 or older, particularly women, have osteoporosis. The prevalence of inadequate intake of calcium and vitamin D is relatively high.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
