Title:Birth weight and age at menopause in Australian
female twin pairs: exploration of the fetal origin hypothesis
Author: S. Treloar, et al.
Address: Queensland, Australia

Summary: Researchers studied 323 Australian female twin pairs where both
co-twins had reached menopause naturally and reported on their weight at birth.
Regression analysis showed no linear association between the 2 variables. In
monozygotic pairs (n=168) this allowed for control of genetic effects as well as
gestation duration. No significant differences dependent on birth weight relative
to co-twin were found for age at natural menopause in either mono or dizygotic
twin pairs, even in pairs whose birth weights differed markedly. There was some
indication that twins with premature ovarian failure were heavier at birth than
twins with normal or later menopausal age. Researchers concluded that the
hypothesis that lower birth weight is associated with earlier menopause is not
supported by their study.
