Abstract
Recent reports have documented that bariatric surgery patients may be at greater risk for bone fractures after surgery. Little is known about the mechanisms responsible for this phenomena. An active lifestyle has been positively associated with bone health in free-living individuals. PURPOSE: The aims of this investigation were to examine bone mineral density (BMD) in patients who had metabolic surgery 9.3±3 yrs earlier and to explore the relationship between self-reported physical activity and bone health in this population. METHODS: Whole body DEXA scans were done using a GE iDXA scanner on 135 former bariatric surgery patients. Additional scans of the hip and lumbar regions were also completed. Patients were asked to report the typical number of weekly workouts (WO) that caused them to sweat or breathe hard. We classified them as either: sedentary (0 WO), irregular (1-2 WO) or active (3 or more WO). ANCOVA was used to compare between group differences, adjusting for age, sex, and ethnicity. RESULTS: 59% of patients reported participating in no activity, 18% were irregular and 23% were active. Total bone mineral density averaged 1.122±.13 g/cm2 in the no activity group which was less (p=.003) than the active group’s 1.195±.14 g/cm2. The no activity group’s greater trochanter density was 0.748±11 g/cm2 which was less (p=.01) than the active group’s 0.817±.14 g/cm2. The mean lumbar vertebrae (1-4) BMD averaged 1.162±.15 g/cm2 which was lower (p=.05) than the active group’s 1.231±.18 g/cm2. CONCLUSIONS: In summary, former metabolic surgery patients who reported vigorous 3 or more days week had significantly higher total bone mineral density in addition to hip and lumbar region compared to those who reported less activity. Appropriate interventions that promote active living after surgery represent a public health priority in this population.

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.
