For women , climacteric is a natural part of getting old , but it may also hurry up the aging physical process , a new subject observe .
Researchers analyze information from more than 3,100 women who had go throughmenopause . The woman give lineage samples so that the researchers could determine each woman ’s " biological age " — that is , the years of their cells , rather than their chronological age . The researchers determined the jail cell ' biologic age by looking at desoxyribonucleic acid methylation , which is a biomarker colligate to aging .
The scientists found that among the woman who were the same chronological age , those who went through change of life earlier in living were biologically older than those who went through menopause later in aliveness . [ 5 Key Nutrients Women Need As They Age ]
On average , they found that menopause rush up cellular aging by 6 percent , said study researcher Steve Horvath , a professor of human genetics and biostatistics at the University of California , Los Angeles ' David Geffen School of Medicine . This means that if two women are 50 years honest-to-god but one womanhood went through climacteric at age 42 and the other belong through menopause at long time 50 , the woman who die through climacteric at 42 would actually be a yr older , biologically , than the other woman , Horvath said .
The women in the study who ’d hadsurgery to get rid of their ovaries(which induces menopause ) before long time 50 were also biologically elder than other fair sex in the study , according to an analytic thinking of their blood cells .
" Our study powerfully suggest that the hormonal change that accompany menopause accelerate biologic ageing in woman , " the research worker wrote in the study , published today ( July 25 ) in the daybook Proceedings of the National Academy of Sciences .
The findings could mean that cleaning lady who go through change of life comparatively early in life history may be at increased risk for eld - relate diseases , or early death , the researcher tell .
But future studies may reveal whethertreatments for menopause symptoms , such as hormone replacement therapy , could neutralize this effect , the investigator say .
Another finding from the newfangled cogitation was that the women who undergo hormone replacement therapy for menopause tended to be biologically younger than other cleaning woman , according to an analysis of buttock - cell sample distribution .
" The big question is , ' Which menopausal hormone therapy offer the strongest anti - aging essence while limiting health risks ? ' " Horvathsaid in a statement .
However , because the unexampled discipline was conducted at a single point in time , it can not confirm that menopause is indeed the cause of the accelerated aging . To corroborate the solvent , future studies will have to count at the biologic age of women ’s cells before and after they go through climacteric , the researchers said .
A separate discipline by the same radical of investigator receive that sleep problems in postmenopausal women were also linked to biologic ripening . In that study , fair sex withsymptoms of insomnia — such as restless eternal rest , difficulty pass asleep and waking up often in the nighttime — tend to be biologically one-time than woman without those symptoms . Menopause is linked with insomnia symptoms — in some cases , because hot flashes and hormonal changes may involve woman ’s slumber .
" Not getting restorative sleep may do more than just affect our functioning the next day ; it might also mold the pace at which our biological clock check mark , " read field of study researcher Judith Carroll , an assistant prof of psychiatry at UCLA ’s Semel Institute for Neuroscience and Human Behavior .
The second study is also published today , in the diary Biological Psychiatry .
