Source of the data:
• The data shown in these maps were collected
through CDC’s Behavioral Risk Factor
Surveillance System (BRFSS). Each year,
state health departments use standard
procedures to collect data through a series of
telephone interviews with U.S. adults. Height
and weight data are self-reported.

38. What is causing America’s
obesity epidemic?

39. Issues related to America’s
obesity epidemic
• In New York City, lawmaker’s attempted to ban
sugary soft drinks larger than 16 ounces.
• School districts around the country are opposing
the federal government’s new federal healthy
lunch program, claiming that students will not eat
the “healthy” food.
• Airlines are considering charging higher prices to
overweight passengers.

40. It takes physical courage to
stand up to enemies. It takes
moral courage to stand up to
friends.

41. How should we combat the
obesity epidemic?
• Do you think government should try to regulate
body weight?
• Should laws prevent businesses from selling
food to obese people?
• Should laws protect obese people from
discrimination?
• Who should pay for medical costs related to
obesity?
• What do you think should be done to decrease
obesity in America?
