The College Alumni Health Study has examined host and environmental ch
aracteristics in youth and adult life as they relate to subsequent dev
elopment of specific chronic diseases. Campus archives have provided p
hysical, psychological, acid social data on some 57 500 men and women
who were born between 1896 and 1934, and who entered Harvard College o
r the University of Pennsylvania between 1916 and 1950, generally at a
ge 17-20 years, These college data have been studied subsequently to a
ssess whether characteristics in youth predisposed students to chronic
diseases (nonfatal and fatal) later in life. Follow-up questionnaires
, mailed to alumni, generally aged 35-85 years, in the 1960s, 1970s, 1
980s, and 1990s have provided mid-life information on the health statu
s and health habits of survivors, and official death certificates have
provided data on decedents. This information has been studied, in fas
hion similar to the college data, for personal characteristics and way
s of living that influenced health and longevity of these middle-aged
and elderly men. Longitudinal observations continue today, in search o
f causes of specific chronic diseases.
