More pregnancy speed up aging in women

Pregnant women's experiences of discrimination and acculturation can impact the brain circuitry of their infants, independent of general stress and depression, according to a recent study by Yale and Columbia University. The research, published in Neuropsychopharmacology, examined 165 pregnant individuals and conducted magnetic resonance imaging (MRI) on 38 infants after birth. The findings suggest that discrimination and acculturation have distinct effects on brain connectivity, particularly weakening connectivity between the amygdala and prefrontal cortex in infants whose parents experienced discrimination during pregnancy.

The number of times a woman becomes pregnant may lead to her more aging, according to a latest study by a group of scientists. They said that it was not quite a surprise that women age according to the number of pregnancy.

Scientific Reports published the study. The researchers noted that pregnancy-related aging would only be apparent after menopause. This time may be after long years of delivering babies.

The lead authors noted that they hypothesised that the hormones that change in the course of Menopause are actually buffering any negative effects of having multiple children. Once a woman reaches, the protective effect is no longer there and the body would not be able to compensate for them, they added.

The researchers analysed data of more than 4,400 women from the United States who were part of a federal health and nutrition survey. They analysed biological aging based on nine biomarkers. These biomarkers were designed to assess metabolic health, liver function, red blood cell disorders, kidney and anemia. They also checked inflammation and immune function.
