Obesity May Leads to Reduced Cognitive Function

People who are overweight do not perform as well on tests of memory and visuospatial ability compared to those with an average weight.

Being obese in older age may lead to poor brain health as higher waist-hip ratio was associated with reduced cognitive function, according to a study.

The association could be explained by an increased secretion of inflammatory markers by belly fat, which has been previously associated with a higher risk of impaired cognition.

Previous studies showed that people who are overweight do not perform as well on tests of memory and visuospatial ability compared to those with an average weight.

For the study, the researchers recruited more than 200 participants who were 60 years and older and used Facebook for at least a year.

“While we have known for some time that obesity is associated with negative health consequences, our study adds to emerging evidence suggesting that obesity and where we deposit our excess weight could influence our brain health. This has significant public health implications,” said Conal Cunningham from Trinity College Dublin in Ireland.

For the study, published in the British Journal of Nutrition, the team analysed data from over 5,000 individuals.

These findings may have significant implications as the global prevalence of dementia is predicted to increase from 24.3 million in 2001 to 81.1 million by 2040.

Reducing obesity could offer a cost-effective public health strategy for the prevention of cognitive decline, the researchers noted. (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)
