Interpretive Summary:

Technical Abstract: Links between short sleep duration and obesity, type 2 diabetes, hypertension, and cardiovascular disease may be mechanistically mediated through changes in dietary intake. This review aims to provide an overview of recent epidemiologic studies on the relationships between habitual short sleep duration and dietary intake in adults. Studies have observed associations between short sleep and higher total energy intake and differences in dietary intake, most consistently higher fat intake, lower fruit intake, and lower quality diets. Evidence also suggests that short sleepers have irregular eating behavior deviating from the traditional 3 meals per day to fewer main meals and more frequent, smaller, energy dense and highly palatable snacks at night. While the impact of short sleep duration on dietary intake tends to be small, if chronically pursued it may contribute to an increased risk of obesity and related chronic disease. Taking into account these epidemiologic relationships and causal evidence between sleep loss and metabolism and cardiovascular function, health promotion strategies should emphasize improved sleep as an additional factor for health and weight management. Moreover, future sleep interventions in controlled studies and sleep extension trials in chronic short sleepers are imperative for establishing the causal relationship between short sleep duration and changes in dietary intake.
