Abstract
Background
Higher-quality diets are associated with better sleep quality in observational studies. However, a better understanding of this association is needed given that dietary modifications could represent a novel and natural approach to achieve better sleep.
Objective
To examine how daytime dietary intakes influence sleep quality on the following night using multiple days of self-reported diet monitoring and objective sleep measured under free-living conditions.
Methods
Participants were younger US adults with average habitual sleep duration between 7 and 9 hours per night. Diet was assessed using the Automated Self-Administered 24-Hour Dietary Assessment Tool. Sleep was measured using wrist actigraphy. Sleep fragmentation index was used for objective assessment of sleep quality.
Results
Thirty-four participants (age: 28.3 ± 6.6 years, BMI: 24.1 ± 3.9 kg/m2, 82.3% males, 50.0% racial/ethnic minority) provided 201 paired diet-sleep data. Greater daytime intakes of fruits and vegetables (β-coefficient (SE) = −0.60 (0.29), P = .038) and carbohydrates (−0.02 (0.007), P = .022), but not added sugar (P = .54), were associated with lower sleep fragmentation index. Trends toward associations of higher intakes of red and processed meat (P = .10) with more disrupted sleep, as well as higher fiber (P = .08) and magnesium (P = .09) intakes with less disrupted sleep, were observed.
Conclusions
Higher daytime intakes of fruits and vegetables and carbohydrates that align with a healthy diet were associated with less disrupted nighttime sleep. A 5-cup increase (from no intake) in fruits and vegetables, meeting dietary recommendations, was associated with 16% better sleep quality. These findings suggest that diets rich in complex carbohydrates, fruits, and vegetables may promote better sleep health.
期刊介绍:
Sleep Health Journal of the National Sleep Foundation is a multidisciplinary journal that explores sleep''s role in population health and elucidates the social science perspective on sleep and health. Aligned with the National Sleep Foundation''s global authoritative, evidence-based voice for sleep health, the journal serves as the foremost publication for manuscripts that advance the sleep health of all members of society.The scope of the journal extends across diverse sleep-related fields, including anthropology, education, health services research, human development, international health, law, mental health, nursing, nutrition, psychology, public health, public policy, fatigue management, transportation, social work, and sociology. The journal welcomes original research articles, review articles, brief reports, special articles, letters to the editor, editorials, and commentaries.
