A Nursing Student Asks the Instructor, "Our Textbook Discussed the Obesity

A nursing student asks the instructor, "Our textbook discussed the obesity paradox in older adults. I am not sure I understand; isn't obesity bad for everyone?" The best response by the instructor is:

A) "While there is evidence that obesity in younger people lessens life expectancy, it remains unclear whether overweight and obesity are predictors of mortality in older adults."
B) "Obesity is usually not a concern in older adults, as most older people tend to weigh less than they did when they were younger."
C) "Obesity is a concern in all age groups; however, over the past decade obesity in older adults has decreased."
D) "Obesity in older adults is less of a concern than we once thought; individuals over age 65 with a higher BMI have a lower mortality rate."
