Much like the rest of the country, the youth of the city of Somerville, Mass., faced an obesity epidemic.

  • By 2003, 44% of all youth were overweight or obese.
  • The rate of obesity was disproportionately high among racial and ethnic minorities.
  • Studies showed that overweight adolescents had a 70% chance of becoming overweight or obese adults.

The city needed proactive strategies to support obesity prevention for both youth and adults. Unfortunately, most previous solutions were not as comprehensive or collaborative as necessary.
