Summary
Parity, or the number of children born, is linked to the age of natural menopause in women. Potential fertility may influence this relationship, despite declining birth rates.
Area of Science:
- Reproductive Endocrinology
- Epidemiology
Background:
- Menopause marks the cessation of menstruation, a natural biological process.
- Factors influencing age at menopause are crucial for understanding women's health and reproductive lifespans.
Purpose of the Study:
- To investigate the association between parity and age at natural menopause.
- To explore potential confounding variables in this relationship.
Main Methods:
- A random sample of 151 Danish women reporting natural menopause age.
- Data collected via questionnaire, including parity and other lifestyle factors.
- Statistical analysis to correct for covariates like birth timing, weight, smoking, and occupation.
Main Results:
- A significant association was identified between parity and age at menopause.
- No evidence of a decline in age at menopause despite reduced average parity in recent decades.
- Potential fertility suggested as a confounding variable.
Conclusions:
- Parity is a significant factor associated with age at natural menopause.
- The lack of a declining trend in menopause age warrants further investigation into confounding factors like potential fertility.
