Habitual Sleep Duration, Daytime Napping, and Dietary Intake: A Mendelian Randomization Study.

ABSTRACT:

Background

Chronic inadequate sleep and frequent daytime napping may inflict deleterious health effects including weight gain, cardiometabolic and psychiatric diseases, and cancer. It is plausible that these relations may be partly influenced by the consumption of suboptimal diets.

Objectives

The study aimed to identify potential causal links of genetically proxied longer habitual sleep duration and more frequent daytime napping on 61 dietary variables derived from an FFQ. In addition, the study aimed to assess potential bidirectional causal links between habitual sleep duration or daytime napping and macronutrient composition.

Methods

Genetic variants robustly associated with habitual sleep duration and daytime napping from published genome-wide association analyses
