er menarche và later menopause are more likely bự reach age 90 than those whose reproductive milestones come at earlier ages, suggests a mới ra study .“ People have always wondered whether the timing of reproductive events affect longevity, but no study bự date has evaluated that relationship, ” said lead author Aladdin Shadyab, of the University of California, San Diego School of Medicine .The research đội used dữ liệu collected from 16,251 participants in the Women’s Health Initiative, starting between 1993 và 1998 và continuing until August năm trước .All the women were born before September 1924 ; 8,892, or 55 %, survived lớn age 90 .Women who were at least 12 years old at menarche were about 9 % more likely bự reach age 90 than those who were younger .And women who were at least 50 when their periods stopped were about đôi mươi % more likely bự reach age 90 than women who entered menopause before age 40. This was true whether menopause was natural or surgical .A longer reproductive lifespan was also tied phệ longevity. Women who menstruated for more than 40 years were 13 % more likely lớn reach age 90 than those who had less than 33 reproductive years, the authors reported in a paper released July 27 by the journal Menopause .Shadyab & colleagues can’t say why later periods & later menopause are tied Khủng longer life, but the links could be related bự lifestyle factors & genetics .“ It is possible that those who begin menstruating later & those who experience menopause at older ages are in better health long term, ” Shadyab told Reuters Health .There could also be genes that affect both the start of periods và menopause & a woman’s length of life, he added .“ Further studies are needed phệ determine why reproductive factors predict living mập age 90 in women, ” he said .Dr. JoAnn Pinkerton of the University of Virginia in Charlottesville, who is executive director of The North American Menopause Society, agrees that lifestyle factors & genetics are likely behind the liên kết between later reproductive milestones & longevity .Pinkerton, who was not involved in the study, said research suggests that hormones that may protect women’s hearts are lost during menopause .Also, she said some behaviors, such as smoking, have an impact on overall health & on the timing of menopause .SOURCE : bit.ly/1Pc1GwHMenopause năm nay .Our Standards : The Thomson Reuters Trust Principles .
