Pregnancies affect women’s life expectancy
A woman’s life expectancy appears to be linked to the birth of her last child. White blood cell telomeres are often longer in women who have had their last late child, which is an indicator of better long-term health and longevity.
In women, there appears to be a link between life expectancy and the birth of the last child, according to a new study by researchers at the North American Menopause Society. The study was published in the English language journal “Menopause”.
Influence of childbirth on women’s longevity?
The length of the leukocyte telomeres can provide important information about the longevity of women, and the researchers found in their study that maternal age at the time of the birth of the last child has a significant impact on telomere length and health. long term.
What are telomeres?
This is not the first time that a woman’s leukocyte telomeres have been linked to their lifespan. Telomeres repeat DNA-protein complexes that protect the ends of chromosomes and have been shown to be essential for maintaining genomic stability, the research group explains.
Telomeres have a significant impact on health
Previous studies have found a link between telomere length and various chronic diseases such as cardiovascular disease, type 2 diabetes, certain neurological diseases, and different types of cancer. This suggests the dramatic effects of telomere length on health.
Where does the evaluated data come from?
The current study analyzed data from more than 1,200 postmenopausal and postmenopausal women from the National Health and Nutrition Survey. In addition, unlike previous studies, this research looked at socio-demographic factors related to reproductive behavior and health decisions.
Longer telomeres thanks to the late birth of the last child
Research has confirmed that a mother’s age at last birth is positively associated with telomere length, meaning that women who have given birth to their last child later in life are likely to have telomeres. longer. These are considered a biomarker of long term health and longevity. Results were limited to women who had one or two live births or who were using oral contraceptives.
Further research is needed in the future to determine whether advancing maternal age leads to telomere lengthening at last birth, or whether telomere length is simply an indication of general health and condition. a woman’s ability to have a child at a later age. , explain the researchers. (as)
