Obesity decreases life expectancy by up to 10 years
Last Thursday (14), the medical journal "The Lancet" published a alarming research, showing that in cases of severe obesity the life expectancy drops in up to 10 years. Thus, weight gain may result in the risk of death before age 70.
The researchers used the largest body of data on obesity and mortality ever performed, with more than 10.6 million participants from 239 studies performed between 1970 and 2015 in 32 countries in North America, Europe, Australia, New Zealand, and eastern and southern Asia.
The survey discarded smokers and former smokers with chronic illnesses and people who died in the first five
The sample was divided into categories, according to their BMI - Body Mass Index, and verified the numbers and causes of death of each group. If all overweight and obese had normal BMI levels, one in five premature deaths would be avoided in North America, one in six in Australia and New Zealand, one in seven in Europe, and one in every 20 in eastern Europe. Asia
The study found that the risk of death before age 70 increased from 19% in men of normal weight to 29.5% in moderately obese men. Among women, this risk increased from 11% to 14.6%.
The World Health Organization (WHO) standard, a BMI of 18.5 to 24.9 is considered normal, 25 to 29.9 excess of weight, 30 to 34.9 moderate obesity, 35 to 39.9 severe obesity, and over 40 morbid obesity. By 2014, more than 1.9 million adults worldwide were overweight, with more than 600 million obese.
Anyone who has never exercised is embarrassed to put on tennis for the first time and often ends up leaving physical activity aside. If you thought that way, you just got one more reason to change your mind immediately: even a person who does the first exercises after age 40 can reduce the risk of cardiovascular disease.
A group of scientists from the Department of Virology and Experimental Therapy of Fiocruz Pernambuco seems to have arrived to an important finding regarding the zika virus. They found a substance capable of blocking the production of zika virus in epithelial and neural cells. According to the experts the study may help produce drugs capable of preventing virus contamination.
