Teenage mothers are more likely to have an early menopause as well as a hysterectomy, according to a study.
It found 43 % of women who had a child while under 20 also went through the menopause by the age of 45. By comparison, 33 % of those who had a child later went on to have an early menopause.
Around half the women who had an early menopause also had a hysterectomy, compared with less than a quarter of those who were older at menopause.
The research was based on the health histories of more than 1,000 women in the Canadian-led International Mobility in Ageing Study.
Women from poorer countries including Brazil and Colombia also reported high rates of early natural menopause compared with those in wealthier nations such as Canada.
Those who experienced trauma in childhood were around 56 % more likely to have an early menopause.
Lead researcher Dr Catherine Pirkle, of the University of Hawaii at Manoa, said: ‘This work implies that early birth or a difficult childhood may be storing up problems which only come out half a lifetime later.’
The findings were presented at the World Congress of Menopause in Vancouver, Canada.
Professor Nick Panay, of Imperial College London, chairman of the World Congress on Menopause’s scientific programme committee, said: ‘The information from this study can be used to counsel women with early childbirth and difficult childhood about their potential risks.’
