A conference on obesity (肥胖症) was recently held in Vienna. Two thousand experts from more than fifty countries attended the conference. According to statistics, 1.2 billion people worldwide are overweight, and 250 million are too fat. Obesity is rapidly becoming a new cause of suffering.
Professor Friedrich Hopichler of Salzberg said: "We are living in the new age but with the metabolism (新陈代谢) of a stone-age man. I have just been to the United States. It is really terrible. A pizza (比萨饼) shop is appearing on every comer. We have been occupied by fast food and Coca-Cola-ization."
Many of the experts stressed that obesity was a potential killer. Hopichler said: "Eighty percent of all diabetics (糖尿病人) are too fat, also fifty percent of all patients with high blood pressure and fifty percent with fatty tissue complaints. Ten percent more weight means thirteen percent more risk of heart disease. Reducing one"s weight by ten percent leads to thirteen percent lower blood pressure."
Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs. "The health insurance pays for surgery (such as reducing the size of the stomach) when the body-mass index (身体质量指数) is more than 40. That is equivalent to a weight of 116 kilograms for a height of 1.60 meters. One should start earlier. "
Toplak said that prevention should begin in school. "Child obesity has a close relation with the time which children spend in front of TV sets. "
