Volunteers needed for study of long-term weight loss
STANFORD -- Although being overweight is associated with a higher
risk of heart attack, stroke and adult-onset diabetes, losing even a modest
amount of weight - say fifteen pounds - can reduce this risk by lowering
blood pressure and cholesterol levels. However, people often find that
maintaining even a modest weight loss is extremely difficult. This winter
and spring, Stanford researchers will examine two new behavioral approaches
to long-term weight loss.
"We are only beginning to learn what sorts of strategies can help people
maintain weight loss over the long haul," said Michaela Kiernan, PhD, research
associate at the Stanford Center for Research in Disease Prevention and
principal investigator of the Stanford Healthy Weight Project. "This study
answers a call from national experts in cardiovascular disease, nutrition
and obesity, who have identified research on behavioral approaches that
improve long-term weight loss as an area of critical priority," said Kiernan,
a specialist in behavioral aspects of nutrition, physical activity and
weight loss.
All study participants will be randomly assigned to one of three study
groups and asked to visit the clinic four times over the course of the
study. Two study groups will also attend behavioral weight-loss classes.
Participants in the "Smart Consumers" class will learn how to critically
evaluate information presented in the media on weight loss, such as the
pros and cons of eating Olestra and other fat substitutes. Participants
in the "Taste-Based Choices" class will learn how to reduce their feelings
of deprivation by improving the taste of low-fat foods and by choosing
which of their favorite high-fat foods to eat in moderation. The third
group of participants, the control group, will only make the clinic visits.
At the end of the study, the researchers will assess whether participants
kept off the weight they lost (expected to be approximately 15 pounds)
during the twelve months after the classes end.
Study participants in the behavioral weight-loss groups will attend
classes on either Tuesday or Thursday evenings from 5:30 to 7 p.m. Fourteen
classes will be held over a period of six months, beginning in early March.
Participants' weight, blood pressure, aerobic fitness and dietary habits
will be assessed during four clinic visits, and feedback will be provided.
All assessments, materials and classes are free of charge.
Kiernan's research is funded by a five-year First Independent Research
Support and Transition (FIRST) Award from the National Heart, Lung and
Blood Institute of the National Institutes of Health.
Healthy men and women who would like to lose 15 pounds and whose present
weight falls within the ranges in the chart below are encouraged to volunteer
for this project. Participants must be over age 25 and must not be diabetic.
Interested individuals will be screened over the telephone and asked to
fill out questionnaires on their dietary attitudes and habits to determine
whether they are eligible for participation. To obtain more information
or to volunteer, call Peggy Raymond, recruitment coordinator of the Stanford
Healthy Weight Project, at (650) 725-0916.
