Antibiotics in later pregnancy ups a child’s asthma risk: study

But the increased chance only applies to children born vaginally, say Danish authors

Exposure to antibiotics during mid-to-late pregnancy increases a child’s asthma risk by up to 34% if they are born vaginally, a Danish study shows.

Researchers from Aarhus University followed up nearly 33,000 children at age 11 years to determine if antibiotic exposure during pregnancy was associated with childhood asthma.
