Babies with adolescent fathers may have problems at birth, such as premature birth, low birth weight and even death, according to a new study by a Canadian research group.
The study was carried out on a batch of over 2.6 million births registered between 1995 and 2000. On the other side of the age spectrum, the researchers found that over 40 years of age were at risk for none of these problems.
In the study, besides the father's age, other factors such as age and mother's health were taken into account.
It has long been established that maternal age increases the risk of fetal death and a whole host of health problems in the newborn.
The study by the Canadian researchers was quite strict, being conducted on a number of 2,614,966 newborns, with married mothers and ages between 20 and 29 years, and multiple births were excluded.
For each of these births, the researchers had access to complete information about the father's age and ethnicity, prenatal care and birth weight. birth of the child.
Women around the age of 20 were most likely to be affected by fertility problems, which generally create problems at birth.
The researchers found that babies with teenage dads they were up to 15% more likely to be born prematurely, 13% more likely to be low birth weight and 22% more likely to die in the first month after birth.
Although the connection between babies with adolescent fathers and their problems at birth is clear, the causes are not so clear.
Given the results of other studies showing that sperm immaturity may contribute to the abnormal formation of placenta in the uterus, the researchers say that biologically it is plausible that the paternal age has an influence on birth.
However, social factors can also influence birth outcomes. Teenage tactics are more likely to come from low-income families and have a poor education, factors associated with poor prenatal care, drug use, cigarettes and alcohol.
