Vitamin D status and bone health in Inuit women 40 years of age and older
Bibliographic record
Abstract
Low serum 25-hydroxyvitamin D (25(OH)D) concentrations and calcium intakes and a high risk of fracture have been separately reported in Inuit women. We examined vitamin D status, nutrient intake, and forearm bone mineral density (fBMD) in Inuit women (n=419, aged 40-90 y) from Nunavut. Fasting serum was assayed for 25(OH)D, osteocalcin (OC) and parathyroid hormone (PTH). Vitamin D status was below optimal (⤠75 nmol/L) in 69.4% of pre- and 37.6% of postmenopausal women. Vitamin D and calcium intakes (per 1000 kcal) tended to increase with age. Low fBMD was observed in 33% of post- (T-score < -1.5) and 2% of premenopausal women (Z-score < -2). Predictors of fBMD included body mass index and OC, and age in the post- and PTH in the premenopausal group. Lower vitamin D status and dietary nutrient density among premenopausal women suggests a greater risk for osteoporosis with aging compared to the previous generation.

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.
