“We uncovered that a considerable proportion of moms with younger youngsters may possibly frequently expose their youngsters to harmful family substances, perhaps mainly because they are unaware that these kinds of products may possibly be damaging,” stated Jiang, who is with Ohio State’s Crane Middle for Early Childhood Analysis and Plan.
The analyze was printed on line a short while ago in the journal Scientific Pediatrics.
The scientists utilized info on 190 people from the Youngsters in Columbus Analyze, a Crane Middle analysis task that adopted youngsters born into very low-cash flow people in Columbus for 5 yrs right after beginning.
When they to start with started off the analyze, moms were being requested about their use of family substances these kinds of as flooring and bathroom cleaners and solvents in the course of being pregnant.
