WEIGHT LOSS STRATEGIES
WORK IN PEOPLE WITH PRE-DIABETES

Adults with pre-diabetes can lose up to 3 percent of their body weight using
diet, exercise and behavioral strategies, according to a systematic review
of studies that analyzed weight-loss strategies for pre-diabetics.
Weight loss is recognized as one of the better ways to keep pre-diabetes from
turning into full-blown diabetes, experts say.
In their examination of nine studies that included a total of 5,168 participants,
Susan L. Norris, M.D., M.P.H., of the Centers for Disease Control and Prevention
and colleagues found that pre-diabetics using weight-loss interventions could
drop between 2 and 3 kilograms, or four to six pounds, in one to two years.
The review is published in the American Journal of Preventive Medicine.
“Although the weight loss demonstrated in this review is small, even
modest loss in general populations may have health benefits,” Norris
says.
People with pre-diabetes
have impaired glucose tolerance that doesn’t
quite rise to the level of a diabetes diagnosis, although the pre-diabetes
condition can be “an important risk factor for the development of type
2 diabetes,” Norris says. Pre-diabetes affects almost 12 million overweight
people ages 45 to 74 in the United States.
Norris and colleagues
examined nine studies on weight-loss interventions among overweight and obese
people with
pre-diabetes. All of the studies were randomized
control trials, the “gold standard” of medical research.
Of the five studies that examined how these interventions affected the development
of diabetes, three showed a significant decrease in the incidence of the disease,
the researchers found.
Overall, the interventions decreased blood sugar levels, blood pressure and
cholesterol levels slightly among pre-diabetics, although not significantly
more than in those who did not participate in the interventions.
Pre-diabetics who had frequent contacts with the health care workers providing
the diet or exercise advice and who kept up with the intervention were most
likely to lose weight, Norris and colleagues conclude.
The study was supported by the Centers for Disease Control and Prevention.
