Nutrient Inadequacy in Korean Young Adults with Depression: A Case Control Study

Area of Science:

• Nutritional Science
• Psychiatry
• Public Health

Background:

• Diet is increasingly recognized as a modifiable factor influencing mental health.
• Understanding the relationship between nutrition and depression is crucial for developing targeted interventions.

Purpose of the Study:

• To investigate the association between dietary patterns and depression in young Korean adults.
• To identify specific nutrient deficiencies and inadequate food consumption in individuals with depression.

Main Methods:

• A case-control study involving young Korean adults diagnosed with depression (n=39) and matched controls (n=76).
• Dietary intake was assessed using food records and food frequency questionnaires.
• Nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were calculated to evaluate nutrient intake quality.

Main Results:

• The depression group consumed significantly less energy, protein, and various micronutrients compared to controls.
• Men with depression showed lower intake of mushrooms and meat; women consumed fewer grains.
• Both genders in the depression group exhibited lower NAR and MAR, indicating widespread nutrient inadequacy and improper consumption patterns.

Conclusions:

• Depressive symptoms in young Korean adults are associated with poor dietary intake and nutrient deficiencies.
• Improving the quantity and quality of meals is recommended for individuals experiencing depressive symptoms.
• Further research into specific dietary interventions for depression is warranted.
