Second-hand smoking dangerous, reveals study

A recent study has discovered a link between second-hand smoking and development of chronic kidney disease (CKD).

The study, published in the Clinical Journal of the American Society of Nephrology, found out that exposure to second-hand smoking increases the risk of various diseases and the researchers investigated the link between exposure to second-hand smoking and CKD.

The study included 131,196 never-smokers who participated in the Korean Genome and Epidemiology Study from 2001 to 2014. Participants were classified into 3 groups based on the frequency of second-hand smoke exposure as assessed with survey questionnaires: no-exposure, less than 3 days per week of exposure, and 3 or more days per week of exposure.

Participants with less than three days per week and those with three or more days per week of exposure had 1.48-times and 1.44-times higher odds of having CKD when compared with participants with no second-hand cigarette exposure

"Second-hand smoke exposure at home or in the workplace is still prevalent despite legislative actions prohibiting public smoking. This exposure was found to be clearly related with CKD, even with less-frequent amounts of second-hand smoke exposure," said Jung Tak Park, the lead researcher.
