Obesity Alone Does not Increase Death Risk: Study

Earlier, a study, published in The Lancet Diabetes and Endocrinology journal, found that women with metabolically healthy obesity were at 39 per cent higher risk of cardiovascular disease

Patients who have metabolically healthy obesity but are free from other metabolic risk factors do not have an increased rate of mortality, a new study has found.

Metabolically healthy obesity is a debatable medical condition characterized by obesity which does not produce metabolic complications.

The study, published in the journal Clinical Obesity, showed that unlike dyslipidemia, hypertension and diabetes — each one of which is related to high mortality risk — obesity alone does not pose any threat to life.

“We are showing that individuals with metabolically healthy obesity are actually not at an elevated mortality rate,” said lead author Jennifer Kuk, Associate Professor at the York University in Canada.

“We found that a person of normal weight with no other metabolic risk factors is just as likely to die as the person with obesity and no other risk factors,” Kuk added.

For the study, the research team followed 54,089 men and women from five cohort studies who were categorized as having obesity alone or clustered with a metabolic factor, or elevated glucose, blood pressure or lipids alone or clustered with obesity or another metabolic factor.

The researchers looked at how many people within each group died as compared to those within the normal weight population with no metabolic risk factors.

They found that one out of 20 individuals with obesity had no other metabolic abnormalities.

“This is in contrast with most of the literature and we think this is because most studies have defined metabolic healthy obesity as having up to one metabolic risk factor,” said Kuk.

“This is clearly problematic, as hypertension alone increases your mortality risk and past literature would have called these patients with obesity and hypertension, ‘healthy’. This is likely why most studies have reported that ‘healthy’ obesity is still related with higher mortality risk,” Kuk noted.

Obesity Spikes up Asthma Risk in Children

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)
