Longer Exposure to Honking Traffic Makes You Obese

For the study, the researchers involved 3,796 adults and examined body mass index (BMI), waist circumference, body fat, central obesity and overweight

Are you obese or overweight? Blame long term exposure to blaring horns and other noise from road traffic, said researchers.

The study showed that a 10 decibel (dB) increase in mean noise level was associated with a 17 per cent increase in obesity.

“Our analysis shows that people exposed to the highest levels of traffic noise are at greater risk of being obese” said Maria Foraster, lead researcher from the Barcelona Institute for Global Health in Spain.

It could be because noise generates stress and affects our sleep. It alters hormone levels and increases blood pressure.

Moreover, among other effects, sleep disturbance deregulates glucose metabolism and alters the appetite, the researchers explained in the paper published in the journal Environment International.

“In the long term, these effects could give rise to chronic physiological alterations, which would explain the proven association between persistent exposure to traffic-related noise and cardiovascular disease or the more recently discovered associations with diabetes and obesity,” Foraster said.

“Our findings suggest that reducing traffic-related noise could also be a way of combating the obesity epidemic,” he noted.

For the study, the researchers involved 3,796 adults and examined body mass index (BMI), waist circumference, body fat, central obesity and overweight.

They also analysed exposure to noise generated by aircraft and railway traffic and found no significant associations except in the case of long-term exposure to railway noise, which was associated with a higher risk of overweight but not of obesity. (IANS)

Obesity Spikes up Asthma Risk in Children

"Addressing childhood obesity should be a priority to help improve the quality of life of children and help reduce paediatric asthma," Finkel noted

Parents, please take note. Obese children are at an increased risk of asthma, a new study has found.

The findings suggest that the incidence of an asthma diagnosis among children with obesity was significantly higher than in those in a normal weight range and that 23 to 27 per cent of new asthma cases were directly attributable to obesity.

“Paediatric asthma is among the most prevalent childhood conditions and comes at a high cost to patients, families and the greater health system,” said co-author Terri Finkel from Nemours Children’s Hospital in Orlando.

“There are few preventable risk factors to reduce the incidence of asthma, but our data show that reducing the onset of childhood obesity could significantly lower the public health burden of asthma,” Finkel added.

For the study published in the journal Paediatrics, the research team analysed medical records of more than 500,000 children.

The researchers reviewed de-identified data of patients aged two to 17 without a history of asthma, receiving care from six paediatric academic medical centres between 2009 and 2015.

Overweight or obese patients were matched with normal weight patients of the same age, gender, race, ethnicity, insurance type and location of care.

The researchers found that obesity among children with asthma appears to increase disease severity. Being overweight was identified as a modest risk factor for asthma, and the association was diminished when the most stringent definition of asthma was used.

“Addressing childhood obesity should be a priority to help improve the quality of life of children and help reduce paediatric asthma,” Finkel noted. (IANS)
