The smoking parents causes the birth of children with defects

One study found that smoking parents can contribute more to the birth of children with congenital heart defects than cases of maternal smoking during pregnancy.
The results of a scientific study conducted by scientists from the Changsha Central University in China showed that researchers were able, by meta-analysis, to detect a relationship between future parents' smoking and risk high to have children with congenital heart defects, In the structure of the heart or large blood vessels, this is a widespread cause of infant mortality.

The study conducted by Chinese researchers included 125 studies conducted from 1971 to 2018 in China and abroad. The results confirmed that men who become fathers after a period of time at the risk of "rewarding" their offspring with a congenital heart defect were observed in children whose mothers were exposed to second-hand smoke because of the fact that men smoked.

"Parent smoking is a major source of smoking for a passive pregnant woman, who is more dangerous for the fetus than for the woman herself," say the researchers.

The researchers' calculations showed that the risk factor for active and passive smoking was 2.18 and 2.56. Doctors therefore advise men who become parents to stop smoking to keep their offspring healthy.
