Obesity and Sexuality Among Older Couples: Evidence From the National Social Life, Health, and Aging Project
Bibliographic record
Abstract
OBJECTIVE: We investigate whether obesity is associated with sexual activity, sexual frequency, and the range of sexual behaviors in heterosexual older couples. We assess to what extent associations between obesity and sexuality are explained by physical, psychological, and sexual health, and by relationship quality. METHOD: We use data from 1,698 older adults in 849 partnered dyads in the 2010-2011 wave of the National Social Life, Health, and Aging Project and conduct couple-level analysis featuring women's and men's characteristics. RESULTS: Women's obesity-particularly at severe levels-is negatively associated with coupled sexual activity, but the association is not mediated by hypothesized mediators. Men's obesity did not have any association with sexual activity. There was no significant difference between overweight and normal weight adults across all three sexuality measures. DISCUSSION: The growing number of older adults with high levels of body mass index, particularly women, may face certain difficulties in maintaining active sexual lives.

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.
