Influence of Menopause Transition and Physical Activity on Stress Perception
Bibliographic record
Abstract
PURPOSE: The transition to menopause is a natural process and a period of significant physical, hormonal and psychological changes that create sources of stress with which women must cope. Lifestyle factors, such as time spent engaging in physical activity of various intensities, may play a role in moderating the psychological impact of menopause. The purpose of this study was to investigate the following two objectives: 1) the longitudinal effect of the transition to menopause on perceived stress, and 2) the association between the volume/intensity of physical activity and stress perceptions during the menopause transition. METHODS: This secondary analysis was performed on on the results obtained of a 5-year observational, longitudinal study on the effects of menopausal transition on body composition and cardiometabolic risk factors. The sample at baseline (year 1) consisted of 102 premenopausal women (age, 49.9 ± 1.9 y; body mass index, 23.3 ± 2.2 kg/m2). Time spent in physical activity of varying intensities (sedentary, light, moderate, vigorous) was determined using accelerometer measurement over a 7-day period. Stress perception was assessed with Cohen’s Stress Perception Scale consisting of 14 self-reported items. RESULTS: Linear mixed model regression analyses revealed no significant effect of time, menopausal status (MS) or interaction between time and MS on women’s stress perception (ps > .05). There were no significant associations between volume of physical activity and stress perception across time and MS. Yearly trends in the data were observed: at year 2 (where the majority of women were perimenopause), time spent in sedentary behavior was associated with higher levels of stress (r = 0.24, p < .05). CONCLUSIONS: These results suggest that the change in menopause status had no effect on stress perceptions. Although our analysis revealed no influence of physical activity on stress in this sample of healthy mid-life women, strategies to diminish sedentary time early in the transition to menopause may be worthy of exploration. Additional lifestyle, emotional and psychosocial risk factors of stress should be examined.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
