Narrator: This is Science Today. There are many factors that cause childhood obesity. According to Patricia Crawford, co-director of the Center for Weight and Health at the University of California, Berkeley, changes in school curriculum play a role in this nationwide epidemic.
Crawford: The P.E. programs have really changed. There's has been such a push on academics, for good reason, but that comes at an expense. Home economics was certainly a course that was taken by many students learning more about nutrition and foods in the past and that has been moved aside for more emphasis on academics.
Narrator: Crawford warns if childhood obesity isn't addressed, it could boost the already high cost of healthcare.
Crawford: There are not enough endocrinologists to handle the number of diabetes we're going to see. There are not enough heart specialists to handle the number of problems that we're going to see. So, prevention is key and it must occur now to reverse this epidemic.
