FAITH LAPIDUS: Body mass index, or BMI, is a measure of a person's weight in relation to height. A person with a BMI of twenty-five to twenty-nine is considered overweight. The World Health Organization defines obesity as a body mass index of thirty or more.
Pacific island nations have an average BMI of around thirty-five -- the highest in the world. The study found that the United States had the single highest average among wealthy countries. American men and women had an average BMI of over twenty-eight. New Zealand was next. Japan had the lowest, at about twenty-two for women and twenty-four for men.
The report had some good news, however, about high blood pressure. The percentage of people with this major cause of heart attack and strokes has fallen since nineteen eighty. Dr. Ezzati credits improved testing and treatment in wealthy countries. He says a decrease in the use of salt and unhealthful fats probably also helped.
