The occupation of future fathers may be associated to a higher risk of birth defects in their infants. A study published online in Occupational and Environmental Medicine has revealed that the risk of birth defects in their offspring is higher if the father has a certain type of job.
Even though earlier studies have associated certain occupations with a higher birth defect risk in infants, they did not link certain birth defects to certain occupations, they rather placed the defects and occupations under one umbrella in order to achieve a larger sample size, leaving the results somewhat obscure.
The new study results were based on data that included the occupation of around 1,000 fathers from the ongoing US National Birth Defects Prevention Study, which investigates various potential risk factors for major birth defects in a large population sample. All men became to father to a child between 1997 and 2004 that had one or more birth defects, including defects amongst stillborn, aborted and live born babies. The team also surveyed slightly more than 4,000 parents of children with no congenial abnormalities telephone interviews.
