GOTHENBURG, NETRALNEWS.COM - Teenagers who are overweight turns out to be 80 percent more likely to suffer a stroke as adults. Being overweight as a child does not cause a stroke in the future. But boys of normal weight at age eight can see the risks jump if they overeat during puberty.
In a warning to juvenile fast food lovers, a study has linked adolescent weight gain to high blood pressure in adulthood. Researchers at the University of Gothenburg in Sweden recommend it is high blood pressure, which is known to weaken blood vessels in the brain, which pose a risk of stroke.
Researchers found an eight-year-old boy, on average being overweight at age 20 had an 80 percent increased risk of stroke later in life. Any increase in the Body Mass Index (BMI) of two points, above the healthy range, increases the odds of 20 percent suffering from a stroke.
The study followed 37,669 men with an average of 38 years, of whom 918 had a stroke. "The rate of stroke has increased among young adults has even declined for older people. Although we do not know the reason for this increase, it happens along with the epidemic of obesity, "said author Dr. Jenny Kindblom, as quoted from Daily Mail.
Every five minutes someone in the UK has a stroke, which occurs when the blood supply to the brain is severed. Obesity increases the risk of ischemic stroke by blocking arteries with fat deposits that can cause blood clots, cutting off the blood supply to the brain. It can also cause hemorrhagic strokes, where weakened blood vessels that supply the brain bursts.
New studies show that this risk may begin in childhood, when 'seeds are sown' so high blood pressure damages blood vessels. Overweight children who become obese adults have a 70 percent higher risk of suffering a stroke, but it increases to 80 percent for those who start with a healthy weight. This shows rapid weight gain during puberty is more dangerous.
The researchers, whose study was published in the journal Neurology, measured male BMI at the age of eight and then 20 years of age. Researchers then followed their development for decades later.
Of the 1,800 who had normal weight at age eight and were overweight as young adults, 67 had stroke or 3.7 percent. There were 990 people who were overweight by the age of eight and 20, 36 of whom, or 3.6 percent, had a stroke.
The study also found that people with a high BMI increase from age eight to age 20 also tend to have high blood pressure as adults. People with high blood pressure tend to have a stroke.
Today's environment is very conducive to obesity can even improve the relationship we see between increased BMI and stroke risk," said Dr. Kindblom.
