An American study published in the British Medical Journal reveals that parents over 45 give birth to babies with health problems.
Between 2007 and 2016, the researchers studied 40,529,905 births in the United States. They observed the age of the parents and the consequences for the health of the baby. The results of the study are published in the British Medical Journal. Conclusion Older parents give birth to poorer children.
The researchers took into consideration gestation time, baby's weight, Apgar score (assessment of the vitality of the child at birth), hospitalization rate in a neonatal unit, the need for antibiotics and the number of cesareans. Maternal side factors have also been studied: diabetes during pregnancy and the number of pre-eclampsia (syndrome responsible for preterm births and intrauterine growth retardation).
More Premature Babies
What risks? The health of the baby, on the one hand. The study points to an increased risk of preterm deliveries, lighter babies with a lower Apgar score than those born to younger parents.
Parents over the age of 45 have an additional 14% chance of giving birth to a premature baby. On the cesarean side, researchers found between 2007 and 2016 that children whose father was over 45 years of age had an additional 18% risk of not being born naturally, compared to children born to parents aged 25 to 34 years.
Surprisingly, the age of the father also affects the mother's pregnancy, according to the study published by the British Medical Journal. During pregnancy, diabetes is 34% riskier for women whose spouse (and father) is in the elderly group.
