If you’ve worried that your pregnancy may have caused ADHD in your child, take a breath of relief. A new study of nearly 13,000 ADHD children finds that low-birth weight, fetal distress, and post-term pregnancy are not factors for ADHD.
And although boys are often diagnosed 2 to 1 over girls (often greater), the researchers say that the risk factors were similar between boys and girls.
Published in December’s online issue of Pediatrics, the study finds that ADHD is very heritable; it is often passed genetically.
Oddly, the researchers did find a correlation to to ADHD when a mother had a urinary tract infection during pregnancy. Other correlations were found if the mother was younger, single, or smoked during pregnancy.
ADHD was more prevalent in mothers who had induced labor. This correlation lacked explanation.
