Biomarkers such as levels of cholesterol in the blood plasma, triglycerides, glucose, urinary creatinine, and anthropometric measures such as the ratio of weight to height, body composition, and body mass index represent keys to monitoring human health and assessing risk for disease. For this reason, educators and counselors in medicine, nutrition, and public health employ many formulae and quantitative relationships that provide means to assess health status and plan corrective actions or therapies for their patients. This is true not only for patients with established heart disease, diabetes, or obesity, but also for individuals who are interested in preventative medicine or personal strategies for maintaining fitness and minimizing the effects of aging.
