Secondhand Smoke Raises Kindergartners' Blood Pressure
Time Magazine has posted an article that discusses a recent study that explored how secondhand smoking affects children. Dr. Giacomo Simonetti, an assistant professor at the Children's Hospital of University of Bern, conducted a study on the effects of parental smoking children. Going into the study he and his team already knew that about half of adults who had hypertension also had high blood pressure as children, and he and his team decided to research how high blood pressure as children turned into hypertension in adulthood.
The research showed that secondhand smoke in preschool age children significantly raised the probability of high blood pressure, even after factors like height and weight were adjusted. Preschoolers exposed to cigarette smoke had a 21% greater risk of high blood pressure compared to children not exposed to the smoke.
That's particularly concerning among five- and six-year olds, since their elevated blood pressure at such a young age primes them for maintaining this hazardous state into adulthood, and for chronic disease as well. “We know that blood pressure during childhood determines blood pressure in adulthood, so if a child has high blood pressure, it is likely to remain high in adulthood,” says Simonetti.
