Parity and age at menopause in a Danish sample.
A random sample of 151 Danish women who had undergone natural menopause reported the age at which this occurred and answered a questionnaire. A significant association was found between parity and age at menopause after correction for the effects of age at the first and last births, weight, smoking and occupation. However, there is no evidence that the age at menopause has fallen in recent decades, even though the average parity in developed populations has dropped dramatically over this period. It is therefore possible that potential fertility is a confounding variable in the relationship between parity and age at menopause.
