Exposure to Traffic-Related Pollution Poses Threat of Asthma in Kids

For the study, the researchers analysed data from 1,522 Boston-area children born between 1999 and 2002.

Long-term exposure to traffic-related pollution may significantly increase the risk of asthma in early childhood, a study has warned.

The findings, published in the Journal of Allergy and Clinical Immunology, showed that living close to a major road was linked to childhood asthma at all ages examined.

“Children living less than 100 metres from a major road had nearly three times the odds of current asthma – children who either experience asthma symptoms or use its medications daily – by ages seven to 10, compared with children living more than 400 metres away from a major road,” said study co-author Mary Rice from the Beth Israel Deaconess Medical Center (BIDMC) in Boston, US.

For the study, the researchers analysed data from 1,522 Boston-area children born between 1999 and 2002.

The researchers used mapping technologies to determine the distance between each child’s home address and the nearest major roadway.

They also linked home addresses to census data and satellite-derived atmospheric data to calculate each participant’s daily exposure to fine particulate matter (PM) — tiny particles suspended in the air that when inhaled deposit in the terminal sacs of the lung.

Fine PM originates from fuel combustion, including traffic, power plants, and other pollution sources, the researcher said.

The research team also examined children’s daily exposure to soot, a component of fine PM also known as black carbon.

The researchers found that traffic-related pollutants appeared to increase asthma risk in childhood.

“Lifetime exposure to black carbon and fine PM were also linked to the asthma in early childhood (ages three to five years), but in mid-childhood (ages seven to 10 years), these pollutants were associated with asthma only among girls,” the researcher noted. (IANS)

High Costs Preventing People to Take Vital Asthma Medication

The results were published in the journal JACI : In Practice

Out-of-pocket costs are preventing many people from taking vital asthma medication, says a new study, calling for urgent interventions to promote discussions between patients and doctors about the cost of medicines to treat asthma.

The most commonly prescribed preventer treatments for asthma contain inhaled corticosteroids (ICS) which, if taken regularly, reduce the severity of the disease and the number of asthma-related deaths, said the researchers.

According to reports, at least one in every 10 asthma patient globally lives in India and the economic costs associated with asthma exceed those of TB and HIV/AIDS combined.

To reach this conclusion, researchers led by The George Institute for Global Health and the Woolcock Institute of Medical Research at UNSW Sydney, surveyed 1,400 people with asthma in Australia and found that half of the adults and one-third of the children in the study were either decreasing or skipping doses of asthma medicines to make them last longer.

“We know that preventer inhalers can be incredibly effective at controlling symptoms and preventing people from being hospitalised or even from dying of asthma, yet our study has found that out-of-pocket costs are preventing many from accessing medicines which can be life-saving,” said senior research fellow Tracey-Lea Laba of The George Institute.

The study found that young male adults were the most likely to under-use asthma treatments.

This was compounded by doctors being largely unaware that out-of-pocket costs were a significant concern for many of their patients, or that some preventers had lower out-of-pocket costs for patients than others.

According to fellow study author Professor Helen Reddel of the Woolcock Institute at UNSW Sydney, asthma is a long-term disease and one where people really need to keep the inflammation under control by taking a preventative medicine and not just relying on short-term symptom relief from a blue inhaler.

“We need doctors to talk to their patients to stress that this Band-Aid approach does not work, and can leave them hospitalised or even worse as a result,” said Reddel.
