Document Summary
Bmi = weight (kg) / height 2 (meters) Used to determine overweight and obesity in the population. Could also use a table that already has calculations done. Obesity: obesity class i: 30. 0-34. 9, obesity class ii: 35. 0-39. 9. Extreme obesity: obesity class iii: >40. Above 25 risk increases and above 30 risk for mortality increases. Prevalence of overweight and obesity in us adults: 1980: 47%; 32% overweight, 15% obese, 1990: 56%; 33% overweight, 23% obese, 2000: 64%; 33% overweight, 31% obese, 2010: 70%; 34% overweight, 36% obese. Prevalence of overweight and obesity in us children and adolescents (6-19: 2010: 33% (15% overweight, 18% obese) Obesity costs: overall medical care costs billion/year. Effects: can"t fit in seats (car, planes, etc. , seat belt wont fit, steering wheel gets in the way, difficulty getting up and down the stairs, fitness levels decline. Become more sedentary, which then leads them to gain more weight, and will then become even more sedentary: slower response speed.
