Children who grow up breathing their parents’ secondhand smoke are more likely to develop a heart rhythm disorder known as atrial fibrillation than the kids of nonsmokers, a recent study suggests.
Based on families in the decades-long Framingham study, researchers found that half of the children of smokers included in the analysis were exposed to at least a half pack, or 10 cigarettes, a day – and for every pack-a-day increase in smoke exposure, kids’ risk of developing atrial fibrillation in adulthood climbed by 18%.
A small part of the risk for adult atrial fibrillation was associated with the tendency of smokers’ children to become smokers themselves as adults, the study team notes in the Journal of the American College of Cardiology.
Smoking may have unintended and unanticipated downstream harms that have not previously been considered as part of the actual total negative consequences of smoking,” said Dr. Gregory Marcus, senior author of the study and an atrial fibrillation researcher at the University of California, San Francisco.
