Abstract

<jats:title>Abstract</jats:title> <jats:bold>Background: </jats:bold>We<jats:bold> </jats:bold>investigated the association of dietary patterns and sleep duration by controlling mental health status (MHS) using a joint modeling approach.<jats:bold>Methods and materials: </jats:bold>The population based cohort study was conducted within the framework of the Isfahan Cohort Study (ICS), including 1383 participants, aged ≥ 35 years were followed from 2007 to 2013. A validated food frequency questionnaire was applied to obtain dietary patterns. Anthropometric measurements, blood pressure, fasting serum lipids and blood sugars were evaluated in both phases of the study. A random effect joint negative binomial and ordinal model were used to estimate diets effect on sleep duration and MHS.<jats:bold>Results: </jats:bold>Three dietary patterns were identified: Healthy, Iranian and Western dietary patterns. After adjustment for potential confounders, the higher scores of Western diet were associated with sleep hours (OR=1.08 and 95% CI: 1.02‒1.12), the higher scores of the Western diet during the 5 year follow-up was associated with greater sleep duration. Sleep duration and MHS were adversely associated (-0.097 and 95% CI: -0.09‒-0.05)<jats:bold>Conclusion: </jats:bold>Joint modeling by MHS, sleep duration was positively affected only by western diet. Iranian and healthy diet weren't associated by sleep hours.
