In an effort to tackle childhood obesity, the Safeway Foundation recently awarded the University of California, Berkeley School of Public Health a grant to promote research aimed at bridging health care facilities and the community. The School will use its grant of $71,000 to launch a referral system to guide at-risk children to health resources, such as sports clubs, in San Francisco. The money is part of a more than $3 million initiative by the foundation and its partners to help launch grass-roots projects that jumpstart physical exercise and health-consciousness efforts among children.
