Abstract

Abstract: Introduction: Sleep deprivation has been associated with numerous chronic diseases, which may be due to the effect of sleep on diet quality. While scientists have found that probable insomnia and/or insomnia symptoms may have a negative effect on diet quality, there is a need to explore this association in a more diverse population. Methods: Cross-sectional population based study using the National Health and Nutrition Examination Survey data from 2009-2014. This survey sample provides nationally representative data from non-institutionalized individuals in the United States. For this study, 16, 454 non-institutionalized U.S. adults representing an estimated 697 million individuals nationwide were selected based on the validity of their dietary and sleep data. The exposure was self-reported sleep duration described as usual sleep hours at night on weekdays/workdays. The outcome measure was the Healthy Eating Index-2010, a measure of diet quality that assesses compliance to the U.S. dietary recommendations. The HEI maximum score is 100, a higher score indicates higher compliance. Results: The average sleep among the study population was 6.9 hrs. Sleep hours were grouped into four categories. Sleep duration between 6 and 7.5 hrs per night served as the reference group. We examined the predictors of diet quality using a simple and multivariate regression and found that individuals that slept less than 4.5 hrs or less than 6 hrs, had 3.2 times and 2.81 times lower diet quality than the reference group. This effect was dimished, but significant after adjusting for age, gender, household-size, race/ethnicity, marital status, education, poverty income-ratio, physical activity, and thyroid diease, <4.5 hrs of sleep -1.71 (95%CI-3.23, -0.19) and 4.5-6 hrs of sleep -1.93 (95%CI-2.81, -1.05). Conclusion: This diverse sample showed a possible association between sleep debt and diet quality after adjusting for confounders. It is possible that the association between sleep and mortality is due to the effect of sleep debt on diet quality. The reverse could be not ruled out due to the study design. However, this information may render insight into the effects of sleep deprivation and how it is associated to other comorbidities. Support (If Any)
