According to a new study conducted by scientists at Northwestern University (Illinois, USA), having many children accelerates the aging of cells of the female body, the results of which are collected by Medical Express.
data on the main 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 the bodies of women with more pregnancies in their body. 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 between 5 months to 2 years which provides clear evidence that having more children, especially more than four or five, increases the risk of suffering from certain diseases and reduces life expectancy, say the Study authors.
Surprisingly, specialists revealed that the epigenetic age of women who were pregnant during the survey was lower than what it should be. 19659002] In this sense, Christopher Kuzawa, author of the study, argues that "the state of pregnancy look young temporarily to a woman." However, there is "a lasting and cumulative relationship between the number of pregnancies and greater access leration of biological age. "
