Original title: Association between magnesium deficiency score and sleep quality in adults: A population-based cross-sectional study.

Under review. A person has not yet checked this summary against the paper. It is written from the PubMed abstract. Until a person checks it, search engines are asked not to list this page.

What the study found

Mixed

A higher magnesium depletion score went with more sleep trouble and sleep disorder, and with sleep apnea (OR = 3.01; 95 % CI 1.37-6.62). No link with restless legs, insomnia or insufficient sleep.
