Lack of exercise increases heart risk among kids

London, May 13 (IANS) Children who are healthy but inactive can unwittingly risk invitation to future heart problems.

A team of Swedish and Danish researchers studied 223 children -- 123 boys and 100 girls, with an average age of 9.8 years, and assessed their physical activity levels over four days.

They found that children, who were physically more active, had a lower composite risk factor score for cardiovascular disease (CVD) than children with lower amounts of moderate to vigorous physical activity, reports the journal Acta Paediatrica.

'It is well known that physical inactivity in adults is associated with a wide range of diseases and all causes of death,' says lead author Tina Tanha from the Department of Clinical Sciences at Skane University Hospital, Malmo, Sweden.

'We believe that our study now demonstrates a clear clinical association between physical inactivity and multiple CVD risk factors in children,' according to a Skane University statement.

The children wore an accelerometer strapped to an elastic waist belt for four consecutive days to measure physical activity levels.

Children were included in the study only if they wore the belt for a minimum of eight hours a day for three days. They also underwent tests for various CVD risk factors, including blood pressure, resting heart rate, fitness and body fat.

Key findings were that the boys were significantly more physically active than the girls, with higher levels of general physical activity, moderate to vigorous physical activity and vigorous physical activity.

    Driving a $900,000 Porsche 918 Spyder to the future

    It’s more than just its inherent speed, or the whooshing noise that fills the cabin like a school choir jamming with James Hetfield. It’s what it represents in an industry full of skeptics. It’s a portal into the future – a time capsule left by some mad scientist born decades too soon. It’s something that shouldn’t exist. And yet it does.

    Arrest warrant sought for S. Korea ferry captain

    South Korean prosecutors sought arrest warrants Friday for the captain and two crew members of the ferry that capsized two days before with hundreds of children on board, a coastguard official said. The captain and most of his 28 crew managed to escape the ferry, and have been criticised for abandoning the ship when so many were still trapped on board. Tracking data from the Maritime Ministry showed the ferry made a sharp turn just before sending its first distress signal on Wednesday morning. Prosecutors said Friday that preliminary investigations showed that captain Lee Joon-Seok had handed the helm to his third officer before the ferry capsized.
