10 Interesting Stats On Asthma!
- Asthma is a chronic inflammatory disease of the airways. It is a respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing.
- The exact cause of asthma is unknown. Trigger and causes of asthma include allergies, tobacco smoke, environmental factors, obesity, genetics, and other factors.
- About 1 in 12 people (about 25 million) have asthma, and the numbers are increasing every year. Asthma rates are higher in children than adults: 1 in 10 children (10%) compared to 1 in 12 adults (8%) have asthma.
- About 1 in 2 people (about 12 million) with asthma have an asthma attack each year. More children (57%) than adults (51%) have an attack. About 1 in 5 children (20%) with asthma will have to visit emergency because of an asthma attack.
- Asthma rates are increasing. In 2001, rates of asthma were 1 in 14 people or 7% of the US population. Today, 1 in 12 people have asthma, 8% of the population.
- The greatest rise in asthma rates was among black children, almost a 50% increase.
- Asthma costs the US about $56 billion in medical costs, lost school and work days, and early deaths.
- Asthma costs the US about $3,300 per person each year in medical expenses.
- More than half (59%) of children and one-third (33%) of adults who had an asthma attack missed school or work because of asthma. On average, children miss 4 days of school and adults miss 5 days of work because of asthma.
- More than 9% of the population of Illinois have asthma, which is higher than other states.
Is There A Link Between Mold and Asthma?
Infants who are exposed to mold in their living environments have nearly a three times greater risk of becoming asthmatic than those who did not have extensive mold exposure in their first year of life. (Medical Evidence that Connects Mold Exposure to Illness Keeps Piling Up)
There have been four key studies that have researched the relationship between mold and asthma. The first study was conducted in Finland in 2001, followed by three other studies between 2012 and 2014 in the United States, Taiwan, and the United Kingdom.
Finish Mold and Asthma Study!
In a 2001 study, Dr. Maritta Kilpelainen at the University of Turku in Finland found a link between mold and illness. Her study surveyed 10,000 students about the dampness of their homes and asked them to report back on colds and other respiratory ailments.
The study made the following conclusions:
- Students who reported having visible mold in their homes were more than twice as likely as others to have asthma. Moldy homes were also linked to a nearly 50% increase in the odds of having at least four colds in a year.
- Students whose homes harbored visible mold or water damage were also at a somewhat higher risk for other infections such as bronchitis and pneumonia.
- Dampness in the home “at least maintains” asthma symptoms, and may also boost a person’s vulnerability to colds and other respiratory infections.
- Mold is an allergen, it is a known trigger of asthma attacks because it triggers inflammation in the upper respiratory tract and, therefore, makes people more susceptible to colds.
Cincinnati Mold and Asthma Study!
The 2001 Finnish study was partly conclusive because the survey showed a link between damp homes and respiratory conditions, including asthma.
Since there was no clear definitive cause and and effect, mold minimizers cite the 2001 study as an anecdotal association, a theory. The theory was put to a test in 2012 by researchers in Cincinnati whose study was more qualitative. Their conclusion: there is a strong indication that mold exposure in infancy causes asthma.
This study was based upon research on approximately 300 children whose ages ranged from one to seven. The researchers found that there are three mold species harmful to children: Aspergillus ochraceus, Aspergillus unguis and Penicillium variabile. These molds, common to water-damaged homes, cause children to develop asthma.
Tiina Reponen, co-author of the study, concluded:
While it is known that mold is a risk factor for asthma, this is the first study that quantitatively measured mold and after adjusting for commonly known risk factors, found an association with asthma. Previously, other studies had shown qualitative or anecdotal associations.
The key take away from this study is that expectant mothers and families with small children should not live in water damaged buildings.
Taiwan Mold and Asthma Study!
The 2014 study out of Taiwan: Current asthma in schoolchildren is related to fungal spores in classrooms, adds further proof that mold does cause asthma.
Researchers studied children, ages 6 to 15, in 44 schools, and made the following conclusion:
Classroom Aspergillus/Penicillium and basidiospores are significantly associated with childhood asthma and asthma with symptoms reduced on holidays or weekends (ASROH). Government health policy should explore environmental interventions for the elimination of fungal spores in classrooms to reduce the prevalence of childhood asthma.
UK Mold and Asthma Study!
Another study in 2014 made similar conclusions about mold and asthma. Dr. Richard Sharpe of the University of Exeter Medical School found that high levels of the fungal species Penicillium, Aspergillus, and Cladosporium poses a significant health risk to people with asthma, worsening the symptoms in both children and adults.
Sharpe and his team reviewed 17 studies that were done in eight different countries and concluded:
Cladosporium, Alternaria, Aspergillus, and Penicillium species were found to be present in higher concentrations in homes of asthmatic participants. Exposure to Penicillium, Aspergillus, and Cladosporium species were found to be associated with increased risk of reporting asthma symptoms by a limited number of studies. The presence of Cladosporium, Alternaria, Aspergillus, and Penicillium species increased the exacerbation of current asthma symptoms by 36% to 48% compared with those exposed to lower concentrations of these fungi, as shown by using random-effect estimates. Studies were of medium quality and showed medium-high heterogeneity, but evidence concerning the specific role of fungal species was limited. (Indoor fungal diversity and asthma: A meta-analysis and systematic review of risk factors)
Other conclusions from this study, included the following:
- Dampness and fungal contamination in the home has been consistently shown to increase the risk of asthma and the severity of its symptoms.
- Majority of the evidence reviewed focuses on the exacerbation of asthma symptoms, and few assess their role in the development of asthma.
- So far Aspergillus and Penicillium species have already been linked to an increase in the risk of asthma development in children, but we know little about the effects of the other species we considered.
- Dampness is one of the major factors affecting the growth of mold inside homes – a problem which has been on the rise as aging houses are sealed and retrofitted with new energy efficient technology. We currently know very little about how people’s living habits can contribute to indoor air quality, and ultimately affect their health. This study highlights the need for homes to have adequate heating, ventilation and home maintenance – all factors that will help to reduce the presence of mold and its effects on asthma symptoms.
The Impact of the NYCHA Ruling on the Issue of Mold and Asthma!
In 2013, the New York City Housing Authority (NYCHA) was sued by residents that accused the agency of violating the Americans With Disabilities Act by not properly addressing moisture problems that caused mold, exacerbating respiratory ailments of residents, particularly children.
A documentary produced by NBC Dateline, called Breathless, furthered the cause of the residents who argued that persistent moisture in their public housing was causing mold issues that led to asthma attacks in their children.
NYCHA settled out of court and agreed to the following:
- Address moisture as the root cause of mold.
- Respond to complaints promptly.
- Recognize mold and moisture as a health threat.
- Recognize asthma as a disability and to make accommodations for tenants with the condition.
This is a historic agreement because it recognizes the causal link between mold and asthma.
Mold Removal Can Improve Health!
It’s proof of common sense that you want to take care of mold in the home. It’s just proving that if you don’t do that, your kids are more likely to develop asthma. (Gary Steven, an allergist at the Allergy, Asthma & Sinus Center in Milwaukee)
Over the past ten years we have talked to hundreds of home and business owners about health symptoms and indoor mold growth. Our experience parallels that of Dr. Selikoff’s with asbestos. We have been in contact with too many individuals that exhibit a cluster of similar symptoms, with the only consistent connecting factor being mold exposure to disregard this data. (Do People Really Get Sick From a Little Mold in Their House?)
Asthma and rhinitis symptoms and the use of medications to treat them were reduced in patients who took part in a randomized controlled trial to see if removing visible household mold would relieve their symptoms.
After a year the intervention group (those whose mold was removed) reduced their use of medications by 22 percent while the controls reduced their medications by 16 percent.
The intervention group also reported about 24 percent net improvement in rhinitis and rhino conjunctivitis symptoms than the control group.
The intervention group also showed an improvement in wheezing that affected their activities like sleeping and speaking (31 percent vs. 7 percent improvement reported by the control group).
To Prevent Asthma, The Cause Must Be Addressed!
Most traditional treatments of asthma focus on medications as opposed to the root cause! (Sanjay Gupta, Mold and Asbestos Blogger)
There is both quantitative and qualitative evidence proving a link between mold and asthma.
Most asthma treatments use medications and inhalers. The problem is that none of the treatments actually address the root cause of asthma. Research and studies cited above and the NYCHA ruling demonstrate that mold contributes to asthma and could indeed be the cause.
If mold is the trigger, then obviously the cause should be addressed.
According to the stats cited earlier in this article, asthma costs the US about $3,300 per person each year in medical expenses. Considering that the cost of mold remediation averages $2,000 to $6,000, it makes long term economic sense to invest in mold remediation if you or someone in your family suffers from asthma.
Failure to address the cause not only negatively impacts the health of the sufferer, but has a significant economic cost from a health care standpoint and lost productivity.
If you or your children suffer from asthma, one of the most important steps that you can take to improving your condition is to determine if you have mold in your home.
