Bone Mass Eight Years After Treatment for Adolescent‐Onset Anorexia Nervosa
Bibliographic record
Abstract
OBJECTIVE: This paper aims to study long-term bone mineral development in former patients with an onset of anorexia nervosa during childhood and adolescence. METHODS: Bone mineral density (BMD) in lumbar spine and total hip was measured in 39 female participants (mean age = 23.1 years, SD 3.5) an average of 8.1 (±3.3) years after treatment start. RESULTS: At follow-up, seven participants (17.9%) still suffered from an eating disorder. Mean BMD in the former patients was within the normal range in the hip but significantly reduced in the spine. Fourteen (36%) of the participants had osteopenia, and three (8%) had osteoporosis in the spine and/or hip. Amenorrhea for more than two years was associated with reduced BMD in the spine, whereas low weight at follow-up was associated with low BMD in both the spine and the hip. CONCLUSION: A large minority of these former patients had low bone mass in young adulthood. In accordance with other studies, our findings support the importance of weight restoration for future bone health in young patients with anorexia nervosa.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
