Psychological stress in the workplace and menstrual function

Area of Science:

• Reproductive Health
• Occupational Health
• Endocrinology

Background:

• Psychological stress is a known factor influencing women's health.
• The impact of occupational stress on specific menstrual cycle parameters requires further investigation.

Purpose of the Study:

• To examine the relationship between psychological stress at work and menstrual function in premenopausal women.
• To assess the risk of anovulation, cycle variability, and specific cycle endpoints associated with stressful work environments.

Main Methods:

• Analysis of daily urine samples and diaries from 276 healthy, working, premenopausal women over five menstrual cycles.
• Measurement of estrogen and progesterone metabolites, with algorithms to determine ovulation and cycle characteristics.
• Logistic regression and repeated measures analyses to model the impact of stressful work (high demand, low control) on menstrual cycle parameters.

Main Results:

• No strong association was found between stressful work and increased risk of anovulation or cycle variability.
• Stressful work did not correlate with short luteal phase, long follicular phase, long menses, or long cycles.
• Women in stressful jobs showed a significantly increased risk (OR=2.24) of short cycle length (≤24 days).

Conclusions:

• Occupational psychological stress, characterized by high demand and low control, does not appear to increase anovulation or cycle variability.
• Stressful work environments are associated with a significantly higher risk of experiencing shorter menstrual cycles.
• Further research is warranted to understand the mechanisms linking occupational stress to shortened menstrual cycles.
