Scientists have established a direct relationship between the number of children that a woman has and the aging of her body. Data from Medical Express
Having many children accelerates the aging of cells of the female organism, according to a new study by scientists at Northwestern University (Illinois, USA), whose findings are collected by Medical Express.
Researchers badyzed data on key markers of cellular aging – telomere length and epigenetic age – in more than 3,000 women aged 20 to 22 years and found that they appeared to be more developed in women having more pregnancies in their reproductive history.
In their study, scientists verified changes in cells during pregnancy related to "adaptive changes in the mother's immune system."
Each pregnancy accelerates cellular aging in 5 months to 2 years, which clearly demonstrates that having more children, especially more than four or five, increases the risk of certain diseases According to the authors of the study, the specialists revealed that the epigenetic age of pregnant women during the survey was lower than what they should be
. Kuzawa, author of the study, argues that "the state of pregnancy makes the woman young and temporary. "However, there is" a lasting and cumulative relationship between the number of pregnancies and a greater acceleration of the biological age. "
