After a study involving more than 3,000 women, the researchers concluded that the main cause of aging women is to have children. Each pregnancy can reach 2 years.
Illustrative photo. Research conducted by scientists at Northwestern University (Illinois, USA), published by Medical Express, argues that having children accelerates the aging of cells of the female organism .
After analyzing data from the leading markers of cellular aging (telomere length and epigenetic age) in more than 3,000 women between 20 and 22 years of age and found that they appear more developed in women's bodies with more of pregnancies in her reproductive history, published by RT.
Changes in cells during pregnancy related to "adaptive changes in the immune system of a mother" were confirmed.
Specifically, each pregnancy accelerates cellular aging between 5 months and 2 years. This is an obvious proof that having children, especially more than four or five, increases the risk of suffering from certain diseases and reduces life expectancy.
Another striking aspect of the research is that the epigenetic age of pregnant women during the survey was lower than it should be.
That is, a pregnancy state makes a woman look younger, temporarily, but nevertheless the relationship between the number of pregnancies and the greatest acceleration of biological age of the woman is more sustainable and cumulative, according to Christopher Kuzawa, author of the study.
