Abstract
Background: Sarcopenia and obesity both negatively impact health including cognitive function. Their coexistence, however, can pose an even higher threat likely surpassing their individual effects. We assessed the relationship of sarcopenic obesity with performance on global- and subdomain-specific tests of cognition. Patients and methods: The study was a cross-sectional analysis of data from a series of community-based aging and memory studies. The sample consisted of a total of 353 participants with an average age of 69 years with a clinic visit and valid cognitive (eg, Montreal Cognitive Assessment, animal naming), functional (eg, grip strength, chair stands), and body composition (eg, muscle mass, body mass index, percent body fat) measurements. Results: Sarcopenic obesity was associated with the lowest performance on global cognition (Est. Definition1 =−2.85±1.38, p =0.039), followed by sarcopenia (Est. Definition1 =−1.88±0.79, p =0.017) and obesity (Est. Definition1 =−1.10±0.81, p =0.175) adjusted for sociodemographic factors. The latter, however, did not differ significantly from the comparison group consisting of older adults with neither sarcopenia nor obesity. Subdomain-specific analyses revealed executive function (Est. Definition1 =−1.22±0.46 for sarcopenic obesity; Est. Definition1 =−0.76±0.26 for sarcopenia; Est. Definition1 =−0.52±0.27 for obesity all at p 0.05) and orientation (Est. Definition1 =0.59±0.26 for sarcopenic obesity; Est. Definition1 =−0.36±0.15 for sarcopenia; Est. Definition1 =−0.29±0.15 all but obesity significant at p <0.05) as the individual cognitive skills likely to be impacted. Potential age-specific and depression effects are discussed. Conclusion: Sarcopenia alone and in combination with sarcopenic obesity can be used in clinical practice as indicators of probable cognitive impairment. At-risk older adults may benefit from programs addressing loss of cognitive function by maintaining/improving strength and preventing obesity.

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
