The number of women and 90 years, the United States live, dramatically increased in the last century. is currently estimated at 1.3 million, it is expected that this demographic 2050. A new study by researchers found to quadruple at the University of California, San Diego Medical that women who later in life menstruation and experience menopause can start have increased nine decades, the chances of survival.
The study, published online on July 27, 2016 The menopause is the first association of reproductive factors with survival to a certain age, to evaluate old as 90 years.
"To achieve longevity, a global public health goal is many of us wondering," how to live longer? "Our study found that women who first menstruation at age 12 or older, of course, experienced menopause or surgically, 50 years or older and the Age 40 years reproduction was the chance of life greatly increased to 90 years," said Aladino Shadyab, PhD, department of family medicine and public Health at the University of California at San Diego School of medicine.
Of the 16,000 participants in the race and ethnic group survived 55 percent by the age of 90. The participants in the Women's Health Initiative (WHI), a national longitudinal research menopausal woman and were followed for 21 years.
"Our team found that women who started at a later age were menstruating less likely to have health problems such as coronary heart disease, and those who experience menopause later in life, his overall health rather in very good condition, which is a may be a possible explanation for our results, "said Shadyab.
The women, menstruation and menopause experienced started at a later age were also less likely to have a history of diabetes or smoking have.
"Factors such as smoking, can damage the cardiovascular system and the ovaries, which can lead to earlier menopause. Women with menopause later and longer life reproduction may have a lower risk of cardiovascular disease," Shadyab said.
Shadyab whose grandfather lived until the age of 102 years and awakened his passion for the study of aging, said further studies to examine how lifestyle, genetics and environmental factors, the relationship between life needed reproduction and persistence explain.
"This study is just the beginning to analyze the factors that can predict the likelihood of a woman to survive into old age," Shadyab said. "With my grandfather as inspiration, I am very happy to take these results and continue to contribute to the science behind longevity".
