The following is a summary of “Associations Between Sleep Duration and Various Metabolic Health Indices Among Adults in the United States: A Multivariate Analysis of Variance (MANOVA) Using National Health and Nutrition Examination Survey (NHANES) 2021 to 2023 Dataset,” published in the January 2025 issue of Primary Care by Feng et al.
Researchers conducted a retrospective study on sleep duration and metabolic health. Both short and long sleep were linked to systolic blood pressure (SBP), diastolic blood pressure (DBP), larger waist circumference, and high-density lipoprotein (HDL).
They analyzed NHANES 2021–2023 data using MANOVA and Bonferroni-adjusted ANOVAs to assess sleep duration (≤5 h, 5–7 h, 7–9 h, >9 h) and metabolic health indices.
The results showed significant group differences between sleep duration and metabolic health indices (Wilks’ Lambda (Λ) = .98, F (3, 5095) = 4.26, P < .001). Sleep deprivation and short sleep were linked to higher DBP (Ps < .01), waist circumference (Ps < .001), and lower HDL (Ps < .05). Long sleep was associated with lower HDL (P < .01) and total cholesterol (P < .01).
Investigators highlighted the detrimental effects of sleep deprivation and short sleep on metabolic health, including elevated BP, waist circumference, and lowered HDL cholesterol. Long sleep was also associated with reduced HDL levels.
