(Caracas, July 29, News24) .- Sometimes there are women who have had many children and who are young but little deteriorated and the reason is that When you have a lot of children, it accelerates the aging of body cells according to a new study from the University of Northwestern (Illinois, USA), whose results were presented by the publication Medical Express.
Researchers analyzed data on key markers of cell 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 her reproductive history.
Through the study, scientists verified changes in cells during pregnancy related to "adaptive changes in the immune system of a mother".
Each pregnancy accelerates cellular aging between 5 months and 2 years, which clearly shows that having more children, especially more than four or five, increases the risk of suffering from certain diseases and reduces life expectancy. the authors of the study.
Surprisingly, scholars revealed that the epigenetic age of women who were pregnant during the survey was less than what it should be.
Thus, Christopher Kuzawa, author of the study, argues that "the state of pregnancy temporarily makes a young woman look". However, there is a "lasting and cumulative relationship between the number of pregnancies and a greater acceleration of biological age."
