Nutritional Intervention for College Students with Depression
This pilot feasibility study examines whether an 8-week nutritional intervention is acceptable and practical for college students experiencing symptoms of depression. The study investigates how sleep, meal timing, and diet interact to influence mood and daily rhythms in a population vulnerable to circadian disruption. Findings will inform the design of larger clinical trials evaluating lifestyle-based interventions for depression.
Participants take part in a 10–12-week study that includes a 2-week baseline assessment followed by an 8-week dietary intervention. Participants are randomly assigned to follow either a Mediterranean diet alone or a Mediterranean diet combined with time-restricted eating. The Mediterranean diet emphasizes fruits, vegetables, whole grains, legumes, nuts, and healthy fats such as olive oil, while limiting red meat and highly processed foods. Study activities include completing questionnaires, wearing a sleep and activity monitoring device, and logging meals using a mobile app. The study includes four visits, two of which involve individualized dietary counseling delivered via telehealth, along with ongoing educational materials and optional additional support throughout the intervention period.
While direct benefits cannot be guaranteed, some participants may experience improvements in mood, sleep, or overall well-being. Participants will receive personalized dietary guidance from a registered dietitian and may receive up to $150 in compensation for completing study requirements.
Eligible participants are college students aged 18 years or older who are experiencing symptoms of depression.
