How is the effect of weight on Survival after a stroke?
According to a new study, severely obese people can survive 62 percent more likely to have a stroke, compared with people of the same age with less weight. Increased excess weight and extra body fat, the probability of Survival of elderly people after a stroke?
The scientists from the University of California, Los Angeles (UCLA) found in their recent study, that an increased proportion of body fat increases the likelihood of Survival after a stroke. The results of the study will be presented at the annual meeting of the American Academy of Neurology in may in Philadelphia.
Protects fat from an untimely death by diseases?
In the current study there was for the first time, evidence that fat can protect against death due to a stroke, experts say. Previous studies had already shown that overweight older people have a lower risk of death due to heart and kidney diseases. Now, the new study shows similar effects for the Survival of a stroke. After it was found that more and more weight in people with kidney and heart diseases, the chances of Survival, wanted to investigate, the research team whether this also applies to the risk of death due to a stroke. The study involved more than 1,000 subjects participated in an average age of 71 years, who had suffered an acute ischemic stroke, the blood flow was blocked to a part of the brain, the scientists report to NBC News.
What is the BMI tells us about our weight?
Scientists have calculated the first of the so-called Body Mass Index (BMI) of the Participants on the basis of their body size and weight. People are considered overweight if they have a BMI of 25 to 29 a BMI over 29 obesity is even. The average BMI for the subjects was 27.5, reports the physicians. The Participants were then divided based on BMI into five categories: underweight, normal, overweight, obese and severely obese. Subsequently, the experts monitored the patients for a period of three months after their stroke, and measuring their degree of disability.
How much the weight affects the chance of Survival after a stroke?
The doctors found that people who were highly obese, had a 62 percent lower probability of dying from a stroke, heirs, compared with people with a normal weight. It has also been shown that obese people had a 46 percent lower risk of premature death. In people with Overweight the risk was still 15 percent lower, compared with people with a normal weight. If people were underweight, this has an impact also on the probability of dying after a stroke. Concerned had of dying a 67 percent higher risk, compared with people of normal weight.
Further research is required
The results were calculated after the researchers already other factors were taken into account, which could affect survival rates, such as high blood pressure, high cholesterol or Smoking. Of the 95 people who were severely obese, died in elf during the study. 19 of the 192 obese subjects died, 58 of 395 obese Participants died, 55 of 327 people with a normal weight died, and six of the 24 subjects with underweight died. But the question is: Why is the protection greater weight before death due to a stroke still? A possible explanation is that people who are overweight or obese, have a nutrient reserve, which can help you to survive in case of prolonged illness, according to the authors. Further research is needed to investigate the relationship between Body Mass Index and stroke in more detail. (as)
