And according to what the British Daily Mail reported, these features have long been associated with longevity and health, with short telomeres often found in people exposed to disease, and researchers studied more than 1,200 women either after menopause or underwent this process from different backgrounds and socio-economic situations, a previous study found On a small scale the presence of longer telomeres in older mothers, but this was observational and had significant limitations.

For example, it could not be ruled out that mothers who had babies later in life had longer telomeres because they were wealthier. Many well-off women are late in starting their family to pursue a profession, while less well-off people tend to get pregnant earlier in life. .

The researchers took into account socioeconomic status in their study. Lead author Chase Latour, an epidemiologist at the University of North Carolina, said: “Women who deliver their last child later in life are likely to have longer telomeres, which are a biological marker of long-term health and longevity. “.

Mother-infant interactions play an important role in a child’s development – anxious or depressed mothers are less able to regulate a baby’s negative mood.

According to experts, 10-20% of women experience mood disorders such as mild depression, irritability, and mood changes during and after pregnancy, as blood tests have shown that those who gave birth to their last child in their teens or twenties had shorter telomeres than those who founded or added a family to. Later.

The researchers say it is possible that birth later in life may affect telomere length and thus increase life span, but this is thought unlikely.

“More research is needed to determine whether an older mother’s age at the last birth prolongs telomeres or whether telomere length acts as a public health proxy and corresponds to a woman’s ability to conceive a child at a later age,” says Dr. Stephanie Faubion. North American Menopause Society (NAMS).
