A US study, published in the journal Menopause, has found an association between reproductive years and ageing. Those with more than 40 reproductive years enjoyed increased odds of living into a 10th decade, scientists from the University of California, San Diego School of Medicine said. “Our study found that women who started menstruation at age 12 or older and experienced menopause – naturally or surgically – at 50 or older, [after] having more than 40 reproductive years, also had increased odds of living to 90 years old,” lead author Aladdin Shadyab said. The longitudinal study followed 16,000 women from racially and ethnically diverse backgrounds for 21 years. More than half – 55 per cent – survived to age 90. It was found women who started menstruation at a later age were also less likely to have certain health issues, like coronary heart disease. They were also less likely to be smokers or have a history of diabetes, the scientists noted. “Factors such as smoking can damage the cardiovascular system and ovaries, which can result in earlier menopause,” Shadyab said. “Women with later menopause and a longer reproductive lifespan may have decreased risk of cardiovascular diseases.” He said more studies were necessary to examine how lifestyle, genetics and environmental factors migh
