Association between intergenerational violence exposure and maternal age of menopause.

OBJECTIVE

To investigate whether maternal violence exposure personally and through her child is associated with an earlier age of menopause, controlling for covariates.

METHODS

Analyses used merged data from two related sources. Although mothers (n = 1,466) were interviewed in 1995 and then 20 years later (2015-17), their children were interviewed in the National Longitudinal Study of Adolescent to Adult Health repeatedly (Waves 1-4, 1994/5 to 2008-2009). Mothers reported their own age of menopause, and mothers and adolescents each reported their own exposure to violence as children and adults.

RESULTS

A mother's own childhood physical abuse (b = -1.60, P < .05) and her child's sexual abuse (b = -1.39, P < .01) both were associated with an earlier age of menopause. Mothers who were physically abused in childhood and have a child who experienced regular sexual abuse reached menopause 8.78 years earlier than mothers without a history of personal abuse or abuse of their child.

CONCLUSIONS

Our study is the first to find that age of natural menopause is associated with intergenerational violence exposures.
