The Menstrual Cycle01:19

The Menstrual Cycle

849
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

Menses Phase01:18

Menses Phase

283
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...

Area of Science:

  • Reproductive Health
  • Occupational Health
  • Epidemiology

Background:

  • Shift work is increasingly recognized as a potential risk factor impacting women's reproductive health.
  • Existing evidence links shift work to menstrual disorders, reproductive disturbances, and adverse pregnancy outcomes.
  • A systematic examination of menstrual irregularities, dysmenorrhea, and early menopause in shift workers was previously lacking.

Purpose of the Study:

  • To investigate the association between shift work and key female menstrual characteristics.
  • Specifically examining irregular menstruation, dysmenorrhea, and the risk of early menopause.

Main Methods:

  • A comprehensive meta-analysis was conducted, searching four major databases (PubMed, Embase, Cochrane, Web of Science) up to December 2022.
  • Data from 21 studies involving 195,538 female participants were extracted and analyzed.
  • Statistical methods included calculating odds ratios (ORs), relative risks (RRs), and hazard ratios (HRs) with 95% confidence intervals (CIs), alongside heterogeneity and bias assessments.

Main Results:

  • The meta-analysis revealed a significant positive association between shift work and irregular menstruation (OR=1.30) and dysmenorrhea (OR=1.35).
  • Shift work was also linked to an increased risk of early menopause (HR=1.09) with no significant heterogeneity.
  • The 21 included studies were of high methodological quality.

Conclusions:

  • Shift workers demonstrate significantly higher odds of experiencing menstrual disorders, dysmenorrhea, and early menopause.
  • These findings underscore the importance of addressing occupational schedules to protect female reproductive health.
  • Implications exist for optimizing working hours and shift arrangements for female employees.
