Rationale: The aging effect of altered body composition would be a decrease in total body water. Edema is not a normal assessment finding in the absence of other pathophysiologic cause. A normal change in aging includes a decrease in muscle mass; therefore bilateral atrophy in biceps and triceps, as well as the deltoid muscle, would be a normal change. Increase in abdominal fat mass is a normal sign of aging. Decrease in bone mineral loss is common in elderly and often presents as Kyphosis or loss of height from vertebral compression.
