The number one scapegoat for chronic bronchitis is smoking, whether direct or indirect.
The fact is that millions of people who never smoked, stopped smoking, or were never heavily exposed to smoking can suffer from chronic bronchitis. Therefore, smoking cannot be the only factor.
A new study in the journal Chemosphere reveals everyday items found in all homes to be an even stronger factor than smoking.
In fact, if you’re exposed to these items regularly, you’re 82% more likely to develop chronic bronchitis.
The study investigated the connection between exposure to volatile organic compounds (VOCs – explained better below) and two lung diseases: chronic bronchitis and emphysema.
The scientists used data from the National Health and Nutrition Examination Survey 2011–2014, which included the full health records of the participants. It also included details of what was found in their urine, with these researchers being particularly interested in specific molecules that indicate that they had been exposed to VOCs.
The researchers tried to answer two main questions:
-
1. They examined how individuals with each VOC-related molecule measured in their urine compared to those without these molecules in terms of having chronic bronchitis or emphysema.
2. They looked at the combined effects of multiple VOCs on the risk of chronic bronchitis and emphysema.
Here’s a breakdown of the key findings:
-
1. Nine VOCs were individually linked to an increased risk of chronic bronchitis, and four VOCs were linked to emphysema.
2. Participants with higher levels of total combined VOCs in their urine were more likely to have both of these lung diseases.
3. When combined, the nine VOCs that were linked with chronic bronchitis increased participants’ risk of this lung disease by 82%.
4. MHBMA3, a metabolite of a VOC called 1,3-butadiene, was most strongly associated with chronic bronchitis.
5. AMCC, a metabolite of a VOC called methyl isocyanate, was most strongly associated with emphysema.
Therefore, exposure to VOCs, both individually and combined, is associated with an increased risk of chronic bronchitis and emphysema.
So, since 1,3-butadiene is such a massive risk factor for chronic bronchitis, what exactly is it? It has previously been labeled as a carcinogen, indicating it can increase the risk of cancer, so it’s surprising that it is still so widely used.
Its main use is in synthetic rubber products like tires, shoes, hoses, seals in appliances and plumbing fixtures, welcome mats, exercise mats, rubber flooring, tennis and other balls, seals in food containers and lids, toys like rubber ducks and squeaky toys, rubber bands, waterproof clothing, and so on.
If you think of how many of these products are inside your home, you can see why the researchers were concerned about the risk for chronic bronchitis.
