Oaxaca of Juárez, July 28th. 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, whose results are collected by Medical Express. 
Researchers analyzed 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 The last ones appear more developed in the organizations of the women with more pregnancies in their reproductive history.
In their study, scientists checked for 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 authors Surprisingly, specialists have revealed that the epigenetic age of women who were pregnant during the research was lower than that. he should be.
In this sense, Christopher Kuzawa, author of the study, argues that "the state of pregnancy makes a young woman look temporarily". However, there is a "lasting and cumulative relationship between the number of pregnancies and a greater acceleration of biological age."
