Although there are many good reasons for proposing the action against obesity in youth, a new study now that the extra weight may increase later in puberty, the risk of multiple sclerosis (MS).
Report of the 10th November edition of Neurology, Harvard researchers found that obesity is age 18 and more than double the risk of a woman developing MS in adulthood compared with their colleagues more easily.
"This is a study shows that obesity leads to a further more a result of unhealthy and obesity in adolescence may a crucial role in determining the risk of MS," said Kassandra Munger, author of the study, a research fellow at the School of Public Health at Harvard University in Boston.
Multiple sclerosis is a chronic central nervous system, according to the National Multiple Sclerosis Society. Although nobody is sure what to believe, the exact cause of the disease, scientists, it is an autoimmune disease. This means that the body's immune system mistakenly attacks its own cells. In the case of MS, the immune system destroys myelin, a fatty substance that covers nerve fibers in the MS Society.
The study included more than 238,000 women in the Nurses Health Study and the Nurses' Health Study II between 1976 and 2002. The women were between 25 and 55 at baseline.
Body Mass Index (BMI) was calculated from information on the women who were what their size and weight than they were 18 and inclusion. A BMI from 18.5 to 24.9 is considered normal, according to the U.S. Centers for Disease Control and Prevention, while 25 to 29.9 is overweight and over 30 is obese.
The women were also invited to identify pictures of nine body silhouettes ranging in size from very thin to very obese to see, and the figure most closely conform to 5, 10 and 20
Women who were overweight at the age of 18 years were 2.25 times more likely to develop multiple sclerosis, the study found. Obesity appears to increase the risk slightly, but not at a level that was statistically significant, "said Munger.
The shape of a large body of 20 years increases the risk for multiple sclerosis by 96 percent, according to researchers. A large body size at age of 5 or 10 is not associated with an increased risk of MS, provided that the woman had lost weight, 20 years.
Although this study was not designed to find the reason for the increase, Munger said that low vitamin D was suspected to play a role in the development of MS, and that obese people are less May the blood level of vitamin D. A Another way to beat Munger, is that fat tissue secretes a large amount of chemicals affect the immune system.
"We're starting to references to things that may predispose a person to get MS," said Dr. John Richert, Executive Vice President for Research and clinical programs at the National Multiple Sclerosis Society. "Until recently we have in the States as a condition for the beginning can not be controlled to be seen, though still mostly in this way, perhaps there are situations in which people can take to reduce your risk a little bit . If all the input data [this study and others is] right, not smoking and maintaining an ideal weight can reduce the risk of multiple sclerosis.
But the current study, added: "As with so many interesting observations, the study raises more questions than answers."
Munger said that the study was conducted only among women, although the results may not apply to men. And besides, he said, the participants were almost all white, so it is not known whether this association would be valid for other races.
