Premature Birth Linked to Asthma

Children born very early - before 32 weeks gestation - had approximately three times the risk of developing asthma/wheezing disorders compared with babies born at term

Is your kid suffering from asthma and wheezing disorders? The reason may be the child’s premature birth, research showed.

The risk of developing these conditions increases as the degree of prematurity increases, the study showed.

The findings are based on a systematic review of 30 studies that investigated the association between pre-term birth and asthma/wheezing disorders among 1.5 million children.

Worldwide, more than 11 percent of babies are born premature.

Across the studies that ranged a time span from 1995 to present, 13.7 percent of premature babies developed asthma or wheezing disorders compared with 8.3 percent of babies born at term, representing a 70 percent increased risk.

“Children born very early – before 32 weeks gestation – had approximately three times the risk of developing asthma/wheezing disorders compared with babies born at term,” the study showed.

“As asthma is a chronic condition, our findings underscore the need to improve our understanding of the mechanisms underlying the association between preterm birth and asthma/wheezing disorders in order to develop preventive and therapeutic interventions,” said Aziz Sheikh of Brigham and Women’s Hospital (BWH) in Boston, US.

Car Pollution: The Cause of Asthma Among Over 350,000 Children in India

South Korea (31 per cent) had the highest proportion of traffic pollution-attributable childhood asthma incidence. The UK ranked 24th of the 194 countries, the US 25th, China 19th, and India 58th

Traffic pollution caused asthma among 350,000 children in India, the second largest after China, in 2015, finds a Lancet study that analysed 194 countries.

The study, published in the Lancet Planetary Health, found that the largest number of cases (760,000) of traffic pollution-related asthma were in China.

It could be because China has the second largest population of children and the third highest concentration of nitrogen dioxide (NO2), which is an indicator of traffic pollution.

India had the next largest number of cases (350,000) due to its large population of children, said researchers from the George Washington University in the US. The US (240,000), Indonesia (160,000) and Brazil (140,000) had the next largest burdens.

“Our findings suggest millions of new cases of paediatric asthma could be prevented in cities around the world by reducing air pollution,” said Susan C. Anenberg, Associate Professor at the George Washington University in the US.

Globally, the study suggests there are 170 new cases of traffic pollution-related asthma per 100,000 children every year, and 13 per cent of childhood asthma cases diagnosed each year are linked to traffic pollution.

South Korea (31 per cent) had the highest proportion of traffic pollution-attributable childhood asthma incidence. The UK ranked 24th of the 194 countries, the US 25th, China 19th, and India 58th.

India ranks below other countries for this metric because although levels of other pollutants (particularly PM2.5) in the country are among the highest in the world, NO2 levels (between 2010 and 2012) in Indian cities appear to be lower than or comparable with European and US cities, the researchers said.

“Improving access to cleaner forms of transportation, like electric public transport and active commuting by cycling and walking, would not only lower NO2 levels but would also reduce asthma, enhance physical fitness and cut greenhouse gas emissions,” Anenberg said. (IANS)
