NEW YORK (Reuters Health) - A program designed to boost
physical activity levels in a low-income, multi-ethnic
community did just that, and led to real health benefits for
Compared with a "control" community, fewer participants in
the get-fit community gained weight and many lost weight,
reducing their risk of type 2 diabetes -- which largely results
from obesity. Residents in the intervention community also saw

years in a low-income, urban district in Norway with high rates
of heart disease, obesity and physical inactivity.
The program involved local political and lay leaders and

reduced by 50 percent. "Although there was an increase in mean
body mass in both districts, the increase in the intervention
district was only half of that seen in the control district,"
the team explains.

significant health effects on risk factors for type 2 diabetes
and cardiovascular disease," Jenum and her colleagues conclude.
