Childhood exposure to secondhand smoke can lead to COPD in future

In fact, childhood exposure to secondhand smoke increased the risk of death from COPD as an adult

According to an American Cancer Society report published on Thursday childhood exposure to secondhand smoke can be linked to various kinds of lung disease decades later. This comes as no surprise as we have been repeatedly warning people of the dangers of secondhand smoke. To come to this conclusion researchers for 22 years, have been following more than 70,000 adults who have never smoked. At the beginning of the study, they were asked whether they lived in a household with a smoker while they were children. Those who did were 31 percent more likely to die of chronic obstructive pulmonary disease (COPD). This is the first study to find a correlation between the two. Exposure to such heavy toxins at a nascent age turns to be deadly for the little ones and its implications can be carried well into the adulthood.

“We know that children exposed to secondhand smoke are more likely to have lung problems, asthma,” said Ryan Diver, the director of data analysis at the American Cancer Society and lead author of the study to a section of the media. The surgeon general defines secondhand smoke as both the smoke from the burning cigarette and the smoke exhaled by smokers. “Whether you are young or old, healthy or sick, secondhand smoke is dangerous,” the report said, “no amount of secondhand smoke is safe.”

“There is evidence that secondhand smoke is even more detrimental than smoking. A lot of cigarettes have filters. So (secondhand smoke) can be more detrimental in that regard,” said Geetha Raghuveer, a pediatric cardiologist at the University of Missouri at Kansas City School of Medicine.

“We need to be aware of the effects of secondhand smoke; they appear to be long-lasting. We need to continue to reduce our exposure of it,” Diver said.

Michael Eriksen, a former director of the Centers for Disease Control and Prevention’s Office on Smoking and Health who was not part of the study, said the most important finding was that “childhood exposure to secondhand smoke increased the risk of death from COPD as an adult. That hasn’t been established before.” Most of the research on secondhand smoke looks at the immediate effects on children or adults.

The COPD mortality increase found in the study may amount to about seven additional deaths per year for every 100,000 participants. The study found slight increases in other health risks. The good news is that the study, while finding increased risk of death from one lung disease, did not find an association with cancer or heart disease, Eriksen said.

“For parents, the implication is don’t smoke at home and don’t smoke around your kids,” Eriksen said.
