What is the formula for adjusted body weight?

The formula for adjusted body weight is designed to provide a more accurate representation of a person's ideal weight, particularly in clinical settings. In the correct choice, the computation takes the difference between current body weight (CBW) and ideal body weight (IBW), multiplies it by a percentage factor, and then adds the ideal body weight back into the equation.

Using the factor of 0.25 suggests a moderate adjustment that reflects the proportion of excess weight accounted for to determine a healthier weight range, particularly useful in cases of obesity or when patients have higher body fat percentages. By adding the ideal body weight instead of the current body weight, the formula emphasizes a target weight that may improve health outcomes without overestimating the weight for individuals with excess weight.

This approach is especially relevant in gerontological nutrition because it accounts for the variations in body composition that occur with aging. It provides healthcare professionals with a practical way to assess nutritional needs and develop appropriate dietary strategies.

In contrast, the other choices either use an incorrect factor for adjustment or misplace the ideal body weight in the final equation, which would distort the intended calculation needed to value the adjusted body weight effectively.
