The Role of Diet in Sleep and Depression

Makena Dyer, B.Sc. and Joannie Dobbs, PhD, CNSHuman Nutrition, Food & Animal Sciences

University of Hawai‘i at MānoaPCCHA Annual Conference, October 13-15, 2014, Seattle, WA

Learning Objectives

• Describe the relationship between sleep difficulty and depression

• Discuss research relating essential nutrients to sleep difficulty and depression

• Identify biomarkers linked to sleep difficulty and depression

• Identify appropriate/helpful questions regarding a patient’s diet that could indicate a role in sleep and depression issues

The Partnerships in Mental Health

• Dr Alan Hawk, M.D.

– Psychiatrist for University Health Services at Mānoa triggered the initial exploration into the diet / mind relationship

The Partnerships in Mental Health

• Discussions with Dr. Hawk and Sue Myhre – nurse practitioner led to the development of a nutrition assessment tool. This tool incorporated many of the health conditions that are seen by multiple practitioners but could have a link to subclinical malnutrition.

The Role of Diet in Mental Health

Common Nutritional Issues in College Students

• Nutritional deficiencies– Iron– Potassium– Protein– Vitamin C

• Calorie restriction

DSM-5 Criteria for Insomnia • “Dissatisfaction with sleep quantity or quality”

– Difficulty falling asleep– Difficulty staying asleep– Waking up early

• Disrupts work and social functioning• Occurs at least 3 nights per week for at least 3 months• Occurs even if circumstances permit sleep• Not related to other medical conditions or psychiatric

drug use

Adapted from The Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition.: DSM-5 by American Psychiatric Association

Estimated Prevalence of Insomnia• Other diagnostic criteria for insomnia

– International Classification of Diseases-10

• Overall prevalence of 10-40% in the U.S.• Prevalence in younger adults (Kessler 2011)

– 23.9% of adults 18-29– 24.2% of adults 30-44

Is There a Connection to Nutrition?

Role of Nutrients in Sleep and Mood

• Nutrients are involved in biochemical processes

• Important process for sleep and mood is neurotransmitter synthesis

Neurotransmitters

Other Issues with Neurotransmitters and Diet

• Bioavailability is also important– Role of carbohydrates

Benton and Donohoe. Public Health Nutr. 1999; 2(3A): 403-9

↑ Carbohydrate intake

↑ Insulin release

↑ Tryptophan available relative to other amino acids

↑ Tryptophan delivery to the

brain via albumin transport proteins

Summary of Nutrients with Special Importance to Sleep and Depression





We Wanted to See if the Relationship Between Depression and Insomnia Could be Seen in the

NHANES Studies

National Health and Nutrition Examination Survey (NHANES)

• Nationwide study on health and nutrition

• 5,000 individuals each year from 15 counties

• Two-year studies since 1999

NHANES Mobile Exam Center

NHANES Datasets

Adapted from wwwn.cdc.gov

• NHANES 2005-2006– Demographics Data– Dietary Data– Examination Data– Laboratory Data– Questionnaire Data

Insomnia and Depression Research Objectives

• Compare nutritional statuses– Individuals with both insomnia and depression– Individuals with neither insomnia nor depression

• Determine what nutrients and biomarkers are most important to understanding these conditions

Study Sample

“Almost always” (16-30 times) in past month for one or more of the following:• Trouble falling asleep• Waking up during night• Waking up too early in the morning

Vozoris. J Hypertens. 2013; 31(4): 663-71

• May persist even with antidepressant use

• For females, antidepressant use with persistent symptoms is associated with lower intakes of certain nutrients

Summary of Nutrients with Special Importance to Sleep and Depression





Questions to Ask in Clinic

• Are you restricting calories?– Concerned about weight?

• What drives your food choices?– Avoiding certain foods can lead to essential

nutrient imbalances?• Vegan diet• “Clean” eating

Summary

• Insomnia and depression can be due to any of several factors

• Neurochemicals and antidepressants are just part of the picture

• Diet and nutrition may address factors not addressed by antidepressants
