Study after study has revealed that secondhand smoke is no joke. Everyone is negatively impacted by the inhalation of smoke, but pregnant women and children are the most vulnerable to its negative affects.

When it comes to children who suffer from asthma, increased symptoms and even death have been associated with exposure to secondhand smoke.

Now, new research conducted by Mayo Clinic Children's Research Center has found that kids with asthma are twice as likely to be hospitialized due to an asthma flare if they are exposed to secondhand smoke.

The study, published in the journal Annals of Allergy, Asthma, and Immunology, reviewed 25 previous studies that had mainly focused on smoking exposure in the home. Results from more than 430,000 kids (average age of 7) were examined.

Authors noted that the results are clear: If you're a parent and your child is substantially more likely to be hospitalized, you should take the initiative and quit smoking.

"The children are missing school if they are hospitalized, and the parents miss work," said senior author Avni Joshi, M.D., in the study's news release. "It is a big financial burden for the family, as well as for society. A child being hospitalized has a high risk of hospital-acquired infection, so I think this is fairly serious."
