Dietary Magnesium Intake Is Associated With Self-Reported Short Sleep Duration but Not Self-Reported Sleep Disorder.

BACKGROUND

Sleep disturbances have become increasingly prevalent in modern society. Research suggests that a deficiency in magnesium (Mg) may contribute to sleep disturbances. This study aims to investigate the association between daily Mg intake and self-reported sleep duration and sleep disorders using data from the National Health and Nutrition Examination Survey (NHANES).

METHODS

The study dataset includes participants from five cycles (2009-2018) of NHANES. The associations between Mg intake and sleep duration are analyzed using weighted logistic regression.

RESULTS

Baseline characteristics of 21,840 participants were analyzed. Mg intake was independently associated with sleep duration (OR = 1.07, 95% CI (1.01-1.14), p = 0.024). Higher quartiles of Mg intake from food were associated with normal sleep duration. However, Mg intake from food in participants with self-reported sleep disorders did not differ from those without sleep disorders (OR = 0.96, 95% CI (0.90-1.03), p = 0.238). Among 3923 participants with Mg supplementation data, no significant differences were found between the top and bottom 50% Mg supplementary groups regarding sleep duration or disorders.

CONCLUSIONS

Dietary Mg intake is independently associated with self-reported short sleep duration but not with self-reported sleep disorders. Mg supplementation is not associated with either self-reported sleep duration or sleep disorders.
