Objective:
The aim of the study was to examine the relationship between heavy menstrual bleeding (HMB) and presenteeism in female workers.
Methods:
A cross-sectional study was conducted using data from 19,451 Japanese women aged 20-60 years who worked at least 30 hours per week. HMB was assessed using the SAMANTA questionnaire, and presenteeism was measured using WFun. Covariates were made for age, menstrual irregularity, education, marital status, income, occupation, and firm size. Statistical analyses were performed using Poisson regression.
Results:
HMB was identified in 47.1% of participants. The prevalence ratio for heavy menstrual bleeding was 1.38 (1.31-1.47) and 1.35 (1.28-1.44) for the age-adjusted and multivariable models, respectively. Higher SAMANTA scores were significantly associated with increased presenteeism (score 3: prevalence ratio 1.26, 95% CI: 1.18-1.34; score 7: prevalence ratio 1.55, 95% CI: 1.44-1.67).
Conclusions:
HMB significantly affects presenteeism in female workers. These findings highlight the need for workplace interventions to improve women's health and organizational productivity.

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
