“A new study reported that children exposed to their parents’ smoking may have a higher risk of developing heart disease in adulthood than those whose parents didn’t smoke. Findings from the study are published in the Journal Circulation.
The research included childhood exposure to parental smoking in 1980 and 1983 and testing with carotid ultrasound data in adulthood was collected 2-25 years later. Blood cotinine levels were collected and frozen in 1980. In households where the parents did not smoke, the cotinine levels were less. Carotid plaques, a major cause of stroke in adulthood was nearly double when one or two parents smoked.
It is clear that parents who smoke expose their children to the risk of possible early strokes. Considering that the study only went 25 years from childhood, I would suspect that the incidence of stroke will significantly increase as more years are studied in these families.
