Over the past two decades, Americans' omega-3 FA intake has been decreasing while the U.S. rate of depression diagnoses and antidepressant prescriptions have been increasing. The purpose of this thesis was to examine the relationship between dietary omega-3 FA intake and depression scores using a sample data set of U.S. adult survey participants in the 2009-2010 National Health and Nutrition Examination Survey (NHANES). Specifically, this study examined the relationship between depression scores and dietary EPA, dietary DHA and total 30-day supplementation of polyunsaturated fatty acids. Results showed that there was a statistically significant relationship between each independent variable and total depression scores; furthermore, indicating that as dietary EPA, DHA and 30-day PUFA intakes increase, depression scores decrease. Although results were statistically significant, the R 2 values suggest low predictive power; thus, results are not generalizable to the entire population.
