A group of scientists at Northwestern University (USA) discovered signs of accelerated aging in women who have several children. This is written by CBS Denver.

The study involved hundreds of women between the ages of 20 to 22 years. Of these, 102 had two children and 28 - three. 507 participants were never pregnant, and the rest had only one child.

Specialists studied biological markers of aging and established the presence of cell changes after the birth of a child equivalent to 0.5-2 years.

In particular, telomeres "aged" by 0.34-3.67 years, and epigenetic age increased by 0.29-0.63 years.

At the same time pregnancy at an early age reduced telomeres more strongly, especially strongly - if it was a question of adolescence.

It was also noted that during the pregnancy epigenetic status of the cells did not reveal signs of aging.

Scientists explained this by the existence of physiological and immunological changes that occur during the development of the fetus. In particular - an increase in the level of estrogen and changes in the composition of immune cells.

Estrogen can reduce the level of oxidative stress and protect telomeres from damage.

Earlier it was reported that related sugar consumption with the development of senile dementia.
