Although the association between elevated serum cholesterol levels
and cardiovascular risk has been known for many years, few studies, with
freely living individuals have used a full complirnent of intervention
strategies to attempt to alter practices associated with elevated serum
cholesterol. Two studies, (Study l, n=4; Study 2, n=8) with l2 middle age men (mean age = 47.3 years) and with elevated serum cholesterol (x= 238.7 mg/dl) are presented that use multiple measures of serum cholesterol
(using the Boehringer Mannheim Reflotron and finger stick technique). The
main intervention strategies included a combination of procedures using
education, frequent serum cholesterol feedback (two to three times per
week), and specific dietary feedback (one to two times per week). A less
intensive intervention that is similar to recent studies in the literature
was also implemented and assessed for half the subjects in Study The
results of the two studies indicated that within approkimately l4 weeks,
the combination of enhanced procedures reduced serum cholesterol by about
l4%, or about double that found in prior studies. The less intensive
intervention showed reductions of 9.1% The use of multiple measures also allowed for the study of intraindividual variability. issues pertaining to
maintenance of effect, cost—effectiveness, and generalizability are also discussed.
