Adherence to the MIND dietary pattern and sleep quality, sleep related outcomes and mental health in male adults: A cross-sectional study
This 2022 study examined the newly proposed hybrid diet, the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) dietary pattern, on its connection with sleep quality and sleep-related outcomes. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), while day-time sleepiness and insomnia were tested through standard questionnaires. Mental health was also evaluated using the 21-item depression, anxiety, and stress scale (DASS-21). As for diet, dietary information was collected through a food frequency questionnaire, which was used to calculate a MIND score (indicates adherence to the MIND dietary pattern). The subjects were 400 male health professionals with an average age of 48 years. While adherence to the MIND diet was not found to be associated with depression, anxiety, or stress, individuals with the greatest adherence to the MIND diet were less likely to have lower sleep quality, compared to those least adherent to the MIND diet. Conforming to the MIND dietary pattern also appeared to be linked with lower odds of daytime sleepiness. With regards to insomnia, following the MIND diet did not strongly correlate with the severity of the sleep disorder, but higher adherence was associated with lower odds of insomnia.
