Since the late 1980s, the United States has witnessed a dramatic increase in average BMI levels and the proportion of individuals categorized as obese. Obesity is a major risk factor for a variety of illnesses, and an increase in obesity is, therefore, implicated in increased health-care costs in the United States. These ultimately translate to a major health and economic problem for the United States. The present analysis examines a pathway to increased levels of obesity as of yet almost entirely unexplored. Specifically, we examine the relationship between obesity and iron deficiency via analyses of blood samples. The current analysis employs public-use data files from the continuous National Health and Nutrition Examination Survey (NHANES) (1999-2006) survey to determine the relationship between obesity and an individual's iron blood content. Results suggest a negative relationship between levels of iron blood content and individual BMI after controlling for other individual characteristics. These results hold for nearly all eight panels tested in the ordinary least squares (OLS) regressions.
