"My feeling is that your neighbors do influence your health," Inagami said. "Who you know and where you go shopping is related to your level of obesity."
Inagami and her colleagues examined census figures from 2000 and linked them to 2,144 Los Angeles County residents who were surveyed about their eating and health habits from 2000 to 2002. The researchers report their findings in the July issue of the American Journal of Preventive Medicine.
