A long-range health study in Framingham Massachusetts, which began
in 1948 and continues to this day involves checking the survivals
among the same 5,200 men and women every two years and carefully
determining the causes of any deaths occurring in the group. A rather
5 surprising conclusion that emerged in 1980 was that the lightest
men had the shortest life expectancy. While the only others for whom
weight seemed to have a significant negative effect on life expectancy
were those who weighed more than 25% above the national average.
Much the same was true of women, with those in the lightest and heaviest
10 groups dying earliest.
These results certainly cast considerable doubts on the validity of
the "Ideal Weights" tables in use since the forties which recommend
weight to height ratios well below the national average. Indeed,
15 they suggest that if any such ideal exists, it is slightly above
the average, whatever fashion may dictate.
