Abstract

Abstract Background The separate relationship between dietary food intake and psychiatric illnesses on individuals' sleep has been discovered in previous investigations. However, it is yet unknown how these variables combine to affect the quantity and quality of sleep.Objective The purpose of the present cross-sectional study was to assess the possible interaction between Dietary Approaches to Stop Hypertension (DASH) and Modified Mediterranean (mMED) dietary patterns (DPs) and psychological ailments (PAs) on sleep quality and duration among Iranian adults, Yazd, Iran.Methods and Materials: Baseline data from a large Iranian cohort study (Yazd Health Study: YaHS-TAMYZ) were used in the current investigation. A validated food frequency questionnaire was utilized to obtain participants' dietary consumption. The adherence level of a priori DPs was calculated according to the earlier scientific literature. The depression, anxiety, and stress scale-21 (DASS-21) questionnaire was employed to assess PAs. To gather information regarding the individuals' sleep quality and duration, a nocturnal sleep questionnaire and short version of the Pittsburgh questionnaire were utilized. Finally, the multivariable adjusted binary logistic regression test was used to examine the interaction between DPs and PAs on sleep quality and duration.Results Participants with the greatest adherence to the mMED DP and with severe depression had significantly lower odds of "low sleep quality" than those without depression signs and the lowest imitation of the diet (P for interaction: 0.039).Conclusion A Mediterranean-like diet might help those with severe depression among people with severe depression. Prospective investigations are needed to confirm this finding. Keywords: Mediterranean; Dietary Approaches To Stop Hypertension; Diet; Depression; Anxiety; Stress; Psychological Well-Being; Sleep
