A new study by the Philadelphia Department of Health is one of a small but growing series of studies that point to the first signs of declining rates of obesity among children. Declines were seen citywide. Despite its own economic challenges, Philadelphia was able not only to achieve an overall decline in obesity but also to make the largest improvements among African American male and Hispanic female students.
Notably, the study doesn't credit one program or policy as the hero of this success story. Instead, it suggests that Philadelphia's comprehensive approach to obesity prevention - a combination of increased access to healthy food, nutrition education and exercise - may be responsible for the reversing obesity trend.
