Kids’ kidneys and smoke

HHS HealthBeat: Say no to smoking.

Smoking and Your Health

From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

Smoking can damage adults’ kidneys – and a study of teens finds even secondhand smoke can damage theirs. At Johns Hopkins Bloomberg School of Public Health, Ana Navas-Acien analyzed data on about 7,500 12- to 17-year-olds. She looked at whether they said they smoked, and at blood chemicals that indicated how much tobacco they had been exposed to – theirs or second-hand. And she looked at their kidney function.

Navas-Acien says smokers had worse kidney health, but even second-hand smoke seemed to have an effect:

“Increasing levels of second-hand smoke exposure were related to worse kidney health.”

She says teens shouldn’t smoke, and can ask adults not to smoke around them.

The study in the journal Pediatrics was supported by the National Institutes of Health.
