METABOLIC IMPACT OF SOCIAL TRANSITIONS IN CANADA: A PROSPECTIVE STUDY OF AGING WOMEN AND MEN IN THE CANADIAN LONGITUDINAL STUDY ON AGING (2011-2021)
Bibliographic record
Abstract
Objective: We aimed to prospectively examine alterations in different social connections and change in waist circumference (WC) among aging Canadians, by gender Design and method: A population-based prospective study of middle-age and older adults in the Canadian Longitudinal Study on Aging (CLSA, 2011-2021) assessed change in marital status, living arrangements, and social participation (waves 1 to 2) and change in waist circumference (WC) at wave 3 (adjusted for wave 2). Stratified, multivariable mixed regression, and predicted means (95% CI), estimated effects by (cis-)gender adjusting for 9 individual and 3 provincial covariables. Sample sizes varied: 13,941 participants for marital and living arrangement transitions and 13,921 for changes in social participation. Results: Overall, mean WC declined over the 6-year follow-up time. We found that alterations in different social connections were associated with subsequent WC changed in a gendered pattern. Among women, only decreased social participation was significantly associated with subsequent change in WC among women (+0.47 cm [0.11, 0.83]) compared to women with stable social participation; although increased social participation also signaled less decline in WC (+0.32 cm [-0.04, 0.68]). Among men, only becoming divorced was significantly associated with subsequent changes in WC (+1.45 cm [0.14, 2.75]), compared to remaining partnered; notably, men becoming widowed had a similar magnitude but a non-significant inverse association (-1.41 [-2.85, 0.03]). Results for changes in living arrangement and subsequent change in WC were null but directions differed by gender. Predicted mean WC at 6-year follow-up were seen for uncertain marital transitions among women (87.95 cm [86.95, 88.94]) and for becoming divorced among men (100.54 cm [99.17,101.91]), placing both in the ‘high risk’ category for diabetes and coronary heart disease. Results were robust to alternative model specification and to further adjustment of all baseline social ties. Conclusions: This study revealed unique gender-specific patterns of change in social connections linked to WC change. Decreased social participation increased mean WC among women, whereas becoming divorced increased WC among men in Canada. Findings underscore the importance of disaggregated data and the unique role of specific changes in social connections for future risk of cardiovascular disease.

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.
