Fathers with professions, such as artists, photographers, mathematicians and office support workers, are at more at risk of having a baby with birth defects, suggest researchers at the University of North Carolina.
Researchers examined career histories of around 1,000 men who had fathered a child with birth defects born between 1997 and 2004, from the records of US National Birth Defects Prevention Study. Careers histories of these men were compared with 4,000 men with healthy babies, who had no congenital abnormalities. Thereafter, a mathematical model classified jobs into 63 groups based on assumed exposure to chemicals or other potential hazards.
Certain types of professionals seemed to have a link with increased risk of having a child with a birth defect. Paternal professions, such as mathematicians, physicists, computer scientists, hairdressers, groundsmen, make-up artists, drivers, crane operators and diggers, were more likely to have a baby with birth defect.
On the other hand, occupations such as architects, health care personnel and foundry workers did not seem to have a connection with birth defect in offspring.
