BMI is a less effective predictor of morbidity and mortality in older than younger adults/ Why is BMI a less reliable tool in older adults?
What will be an ideal response?
Ans: The BMI is calculated using height and weight. Getting an accurate height may be more difficult in older adults who have compressed vertebrae or kyphosis which has reduced normal height. On average, older adults have lost muscle tissue which has been replaced with fat tissue and BMIs were developed with measurements of younger adults. Dehydration can introduce further errors into the interpretation of a BMI in an older individual. Thus, less weight may be due to less muscle and body water.
