TUESDAY, June 29 (HealthDay News) -- A community-based diabetes
prevention program helps people lose weight and lower blood sugar
as effectively as individual counseling from health professionals,
finds a new study.
Participants in the Healthy Living Partnerships to Prevent
Diabetes study were divided into two groups. Those in the lifestyle
intervention program received six months of weekly group behavioral
weight loss sessions run by lay community health workers, followed
by monthly follow-up meetings, where they were encouraged to
improve their eating habits and exercise up to 180 minutes per
week. Participants in the usual care group received two visits with
a dietitian and a quarterly newsletter with tips for lifestyle
After 12 months, those in the lifestyle intervention group lost
an average of 7.3 percent of body weight and reduced their blood
glucose levels by an average of more than 4 mg/dl (from 105.8 to
101.2 mg/dl), compared with an average weight loss of 1.3 percent
and an average glucose level reduction of less than 2 mg/dl among
those in the control group.
The results were to be presented Tuesday at the American
Diabetes Association's Scientific Sessions in Orlando, Fla.
The lifestyle intervention program used in the study was modeled
after one used in a landmark U.S. government-funded Diabetes
"In the Diabetes Prevention Program, professional behavioral specialists worked with participants with pre-diabetes in one-on-one sessions. We trained some of our patients with diabetes to work as lay community health workers with groups of participants with pre-diabetes, so we really didn't expect to see quite as good a weight loss result as we did, but we were very pleased to see it," Dr. David Goff, lead author of the new study and chair of the epidemiology and prevention department at Wake Forest University School of Medicine, said in an ADA news release.
"Given that our weight loss results look as good as the DPP, this approach shows great promise for preventing diabetes. It's a very translatable intervention to deliver in public health settings. We think this approach could be replicated at diabetes care centers across the country," he added.
Pre-diabetes -- which occurs when blood glucose levels are
between 100 mg/dl and 125 mg/dl -- is defined as having blood sugar
that is higher than normal, but not high enough to be considered
type 2 diabetes. If blood sugar levels reach 126/dl, an individual
is considered to have diabetes.
