The prevalence of coronary heart disease (CHD) risk factors in law enf
orcement personnel compared to that in the general population was stud
ied by determining the predicted 10-year risk for developing CHD (CHD1
0, expressed as %) in subjects from the Iowa Department of Public Safe
ty and comparing it to the average CHD10 for similarly aged subjects i
n the Framingham Heart Study cohort. The Iowa data included measures o
n 388 men from 30 to 64 years old, 246 of whom were measured in 1980-1
981 and again in 1992-1993. The CHD10 came from an algorithm developed
using the Framingham data; it included measures of age, gender choles
terol, HDL-C, systolic blood pressure, smoking habit, glucose level, a
nd left ventricular hypertrophy (EGG criteria). For this group, averag
e CHD10 was reported by age in five-year increments [Circulation 83:35
6, 1991]. The Iowa subjects (n = 388) did not show a statistically sig
nificant difference in CHD10 from the reference population (8.9% versu
s 7.9%). The change with age was very similar in the two groups; for I
owa (n = 388) the estimate was CHD10 = -16.5 + .59 (age); for Farmingh
am it was CHD10 = -17.5 + .60 (age). The change in individual risk fac
tors with time was also similar in both groups; the per year change in
CHD10 in the Iowa subjects, which was measured twice (n = 246, 0.63%)
, did not differ statistically from the 0.60% change predicted by the
Framingham model. These results suggest that, for The risk factors con
sidered here, the 10-year probability, of developing CHD among Iowa la
w enforcement personnel is similar to that found in the Framingham pop
ulation. (C) 1997 Wiley-Liss, Inc.
