Stephens, Laurie S., "Implementation of Nutritional Screening in Adults (Ages 19-65) with Major Depressive Disorder: An Integrative Review" (2023). Doctoral Dissertations and Projects. 4881.
The World Health Organization estimates the total percentage of depression at 3.8% and projects it to be the leading cause of global disability by 2030 (WHO, 2023). The economic burden for adults with major depressive disorder in the United States is estimated at a staggering annual cost of 236 billion dollars (Greenberg et al., 2018). Nutritional psychiatry is a growing subspecialty focused upon how diet can improve mental health outcomes. The evidence shows a correlation between diet and depression, influencing questions on how this translates to current dietary recommendations and treatment. An integrative review of current literature was performed to explore the state of the science for major depressive disorder and the implementation of nutritional screening. Findings reflect a lack of both validated screening instruments and standardized nutritional guidelines for major depressive disorder in adults. Clinical barriers were identified through the integrative review with evidence-based practice recommendations.
