Sexuality and Cognitive Status: A U.S. Nationally Representative Study of Home‐Dwelling Older Adults
Bibliographic record
Abstract
OBJECTIVES: To determine patterns and prevalence of sexual behavior, problems, and attitudes in individuals with different cognitive status. DESIGN: We used data from the National Social Life, Health, and Aging Project to describe the relationship between sexual behavior, function, and cognitive status (normal, mild cognitive impairment, dementia), classified using an adapted Montreal Cognitive Assessment (MoCA) (0-30 points). SETTING: U.S. home-dwelling older adults. PARTICIPANTS: Nationally representative probability sample of 3,196 adults (1,682 women, 1,514 men) aged 62 to 91 (mean 72). MEASUREMENTS: Cognitive status and sexual activity, problems, and attitudes. RESULTS: The weighted response rate was 74%. Mean MoCA score was 22.7. Of partnered people with dementia, 59% of men and 51% of women were sexually active, including 41% of those aged 80 to 91; 46% of all men (95% confidence interval (CI)=37.8-53.2%) and 18% of all women (95% CI=13.6-21.5%) with dementia were sexually active. The rate of sexual function problems was high across gender and cognitive groups (77%). Having sex primarily out of obligation was similar across cognitive groups for women (12%) and higher in men with dementia (17%) than other men (2-5%; P <.001). The majority of people were having sex less often than they would like. Few men (17%) or women (1%) with dementia talked with a doctor about sex. CONCLUSION: Many home-dwelling men and women with dementia are sexually active. Although the rate of sexual function problems was uniformly high, people with lower cognitive function infrequently discussed sex with a physician.

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.
