Problem: Body mass index (BMI) is a measure of body fat that is based on both height and weight. The World Health Organization and National Institutes for Health define a BMI of over 25.0 as overweight; this guideline is typically applied to adults in all age groups. However, a recent study has reported that individuals of ages 65 or older with the greatest mortality risk were those with BMI lower than 23.0, while those with BMI between 24.0 and 30.9 were at lower risk of mortality. These findings suggest that the ideal weight-for-height in older adults may not be the same as in younger adults. Looking for Assignment Help?
