Poor Aerobic Fitness Increases Risk of Diabetes in Kids

Their aerobic fitness was determined by measuring peak oxygen uptake during a maximal exercise test

Lack of exercise, particularly poor aerobic fitness, in children increases their risk for developing Type-2 diabetes and cardiovascular disease, says a new study.

Children with poor aerobic fitness in proportion to their total body mass were found to have a significantly higher risk of Type-2 diabetes and cardiovascular disease than their peers having better aerobic fitness.

“Measures of aerobic fitness that are based on total body mass are better at predicting the risk of Type-2 diabetes and cardiovascular disease than measures that are based on skeletal muscle mass,” said Andrew Agbaje, lead researcher from the University of Eastern Finland.

“However, they exaggerate the role of aerobic fitness in children’s health,” he added.

For the study, researchers determined threshold values of aerobic fitness for 352 children, aged between 9 and 11 who are at an increased risk of Type-2 diabetes and cardiovascular disease.

Their aerobic fitness was determined by measuring peak oxygen uptake during a maximal exercise test.

The team also calculated variables indicative of the risk of Type-2 diabetes and cardiovascular disease, such as waist circumference, blood levels of insulin, glucose, HDL cholesterol, and triglycerides as well as blood pressure.

The study, published in the journal Scandinavian Journal of Medicine & Science in Sports, found that the traditional way of expressing aerobic fitness in proportion to total body mass overestimates the role of aerobic fitness in identifying children at an increased risk of these diseases.

“We should be cautious when interpreting aerobic fitness measures that are proportioned to total body mass in order to correctly identify children who truly need health and lifestyle intervention,” Agbaje noted. (IANS)

Nose of Kids Hold Clues to Serious Lung Infections

Experts say this breaks with traditional thinking that symptoms predict whether either a virus or bacteria is causing the illness and could impact a decision of whether or not to use antibiotics

Tiny organisms in a child’s nose could offer clues to improving the diagnosis and treatment of severe lung infections, a new study suggests.

The study found that the composition of the microbiome — bacteria and viruses found in vast numbers in the body — was altered in the noses of children with respiratory infections, compared with his healthy peers.

This difference predicted how much time children had to spend in hospital and helped spot those likely to recover naturally, potentially reducing the need for antibiotics, said researchers from the University of Edinburgh.

“Our findings show, for the first time, the total microbial community in the respiratory tract — rather than a single virus or a bacteria — is a vital indicator of respiratory health. This could impact how doctors diagnose LRTIs and use precious antibiotics to fight infections,” said lead author Debby Bogaert, Professor at the varsity.

Lower respiratory tract infections (LRTIs), including pneumonia and bronchiolitis, are a leading cause of death. Symptoms include, shortness of breath, weakness and fever.

It was found that the microbiome in the back of the nose and throat was related to that seen in the lungs, making it easier to understand and diagnose infections.

For the study, published in The Lancet Respiratory Medicine, the researchers studied more than 150 children under the age of six, hospitalised with LRTI. They compared them with 300 healthy children.

Children with LRTI had a different microbiome profile — including the types and amounts of individual viral and bacterial organisms — compared with the healthy children.

These profiles could identify 92 per cent of children as being healthy or ill when combined with factors like the child’s age. This was true no matter what symptoms the child had.
