问题     A long-range health study in Framingham, Massachusetts, which began in 1948 and continues to this day, involves checking those who remain alive among the same 5,200 men and women every two years and care- fully determining the cause of any deaths occurring in the group. A rather astonishing conclusion that became known in 1980 was that the lightest men had the shortest life expectancy while the only others for whom weight seemed to have a significant opposite effect on life expectancy were those who weighed more than 25 percent above the national average. Much the same was true of women, with those in the lightest and heaviest groups dying earliest. These results certainly threw many doubts on the validity of the "Ideal Weights’ tables in use since the 40th which speak in favor of weight to height ratios well below the national average. Indeed, they suggest that if any such ideal exists, it is slightly above the average, whatever fashion may be.
选项 A、The Framingham Health Study
B、5,200 Men and Women Can’t be Wrong
C、Fashion is Wrong about Weight
D、Weight and life Expectancy: Unexpected Proof
