Association between menopausal symptoms and workplace mistreatment in Japanese workers: A cross-sectional study

Objective: Workplace mistreatment impacts worker well-being, yet its association with menopausal symptom severity remains insufficiently understood. We hypothesized that higher symptom severity is associated with a higher likelihood of experiencing workplace mistreatment. Methods: This cross-sectional study included 16,764 Japanese female workers (aged 40–60 years). Menopause symptoms were measured using the Menopause Rating Scale; mistreatment was quantified using a seven-item. Robust Poisson regression estimated prevalence ratios (PRs) for these associations and trends. Results: Significant dose-response relationships were observed across overall MRS and all subscales (all P for trend < 0.001). Compared to the none group, adjusted PRs for mild, moderate, and severe symptoms were 1.56 (95% CI: 1.45-1.68), 2.08 (1.95-2.23), and 2.87 (2.68-3.09), respectively. Conclusions: The dose-response association highlights a vulnerability for symptomatic workers. Targeted organizational support will be essential to ensure workplace equity.
