Asthma In Childhood Can Trigger COPD Later: Lancet

While smoking remains the biggest risk factor for chronic obstructive pulmonary disease (COPD), childhood illnesses such as asthma, bronchitis, pneumonia, allergic rhinitis and eczema also amplify the disease, say researchers.

Three-quarters of COPD cases have their origins in poor lung function pathways beginning in childhood, according to a cohort study published in The Lancet Respiratory Medicine journal.

A second study in the journal suggests that there could be a window of opportunity during childhood to reduce the risk of poor lung function in later life.

“These findings highlight the importance of preventing both early life adverse exposures that could lead to poorer lung growth and adult risk factors contributing to accelerated lung decline,” says Professor Shyamali Dharmage from School of Population and Global Health, The University of Melbourne, Australia. COPD is expected to be the third-largest cause of death globally by 2030. “It is important that we identify its key causes so that this burden can be reduced,” Dharmage added.

Reduction of maternal smoke exposure and personal smoking and promotion of immunisation are identified as public health targets to prevent poor lung function pathways.

“Doctors and patients with asthma should be made aware of the potential long-term implications of non-optimal asthma control throughout life, and this should be investigated in future research,” the study authors noted. In the first study, 2,438 participants from the Tasmanian Longitudinal Health Study (Australia) were tracked from childhood to the age of 53.

In the second study, 2,632 participants were tracked from birth to 24 years old and their lung function was measured. In the second study, the authors found that around three-quarters of infants aged one to six months with poor lung function improved throughout their childhood, indicating a window of opportunity to increase lung function and potentially reduce risk of COPD in later life.

Asthma Ups The Chance Of Obesity: Study

The increase in the risk of obesity was even greater in people whose asthma began in adulthood.

While obesity is already known as a risk factor for developing asthma, a new research led by one of an Indian-origin has showed that people with the airway disease are also more likely to become obese.

The study indicates that those who develop asthma as adults and those who have non-allergic asthma are at the greatest risk of obesity.

The relationship between asthma and obesity is more complex than previously thought and more research is needed to better understand and tackle these two growing health challenges, the researchers said.

“We already know that obesity can be a trigger for asthma, perhaps via a physiological, metabolic or inflammatory change,” said Subhabrata Moitra, research student at the ISGlobal – the Barcelona Institute for Global Health in Spain.

However, the researchers do not know the reason why having asthma increases the risk of developing obesity or whether different asthma treatments have any effect on this risk.

The team included 8,618 people from 12 countries who were followed for 20 years.

They found that 10.2 per cent of people with asthma at the start of the study had become obese ten years on. Among people who did not have asthma, 7.7 per cent were obese ten years later.

The increase in the risk of obesity was even greater in people whose asthma began in adulthood. It was also greater in people who had asthma but did not suffer with allergies, the findings showed.

The results were presented at the European Respiratory Society International Congress in Paris. (IANS)
