Abstract

Background Self-reported short and/or long sleep duration have been associated with adverse cardiometabolic health outcomes in laboratory and epidemiologic studies, but interpretation of such data has been limited by methodological issues. Methods Adult respondents of the 2007-2008 US National Health and Nutrition Examination Survey (NHANES) were examined in a cross-sectional analysis (N=5,649). Self-reported sleep duration was categorized as very short (<5hrs), short (5-6hrs), normal (7-8hrs) or long (≥9hrs). Obesity, diabetes, hypertension, and hyperlipidemia were assessed by self-reported history and objectively. Statistical analyses included univariate comparisons across sleep duration categories for all variables. Binary logistic regression analyses, cardiometabolic factor as outcome and with sleep duration category as predictor, were assessed with and without covariates. Observed relationships were further assessed for dependence on race/ethnicity. Results In adjusted analyses, very short sleep was associated with self-reported hypertension (OR=2.02, 95%CI[1.45, 2.81], p<0.0001), self-reported hyperlipidemia (OR=1.96, 95%CI[1.43, 2.69], p<0.0001), objective hyperlipidemia (OR=1.41, 95%CI[1.04, 1.91], p=0.03), self-reported diabetes (OR=1.76, 95%CI[1.13, 2.74], p=0.01), and objective obesity (OR=1.53, 95%CI[1.13, 2.06], p=0.005). Regarding short sleep (5-6hrs), in adjusted analyses, elevated risk was seen for self-reported hypertension (OR=1.22, 95%CI[1.02, 1.45], p=0.03) self-reported obesity (OR=1.21, 95%CI[1.03, 1.43], p=0.02) and objective obesity (OR=1.17, 95%CI[1.00, 1.38], p<0.05). Regarding long sleep (≥9hrs), no elevated risk was found for any outcomes. Interactions with Race/Ethnicity were significant for all outcomes; race/ethnicity differences in patterns of risk varied by outcome studied. In particular, the relationship between very short sleep and obesity was strongest among Blacks/African-Americans and the relationship between short sleep and hypertension is strongest among non-Hispanic Whites, Blacks/African-Americans, and non-Mexican Hispanics/Latinos. Conclusions Short sleep duration is associated with self-reported and objectively-determined adverse cardiometabolic outcomes, even after adjustment for many covariates. Also, these patterns of risk depend on race/ethnicity.

TL;DR

In 2007–2008 NHANES adults, very short sleep (<5 h) was associated with several self-reported and objectively determined cardiometabolic risk factors after adjustment, while long sleep (≥9 h) showed no elevated risk. These patterns varied by race/ethnicity.

Key findings

  • Very short sleep (<5 h) was associated in adjusted analyses with self-reported hypertension (OR=2.02, 95%CI[1.45, 2.81]), self-reported hyperlipidemia (OR=1.96, 95%CI[1.43, 2.69]), objective hyperlipidemia (OR=1.41, 95%CI[1.04, 1.91]), self-reported diabetes (OR=1.76, 95%CI[1.13, 2.74]), and objective obesity (OR=1.53, 95%CI[1.13, 2.06]).
  • Short sleep (5–6 h) was associated in adjusted analyses with self-reported hypertension (OR=1.22, 95%CI[1.02, 1.45]), self-reported obesity (OR=1.21, 95%CI[1.03, 1.43]), and objective obesity (OR=1.17, 95%CI[1.00, 1.38]).
  • Long sleep (≥9 h) showed no elevated risk for any outcomes after adjustment; elevated risk was found only for objective diabetes in unadjusted analyses.
  • Race/ethnicity interactions were significant for self-reported and objective hypertension, hyperlipidemia, diabetes, and obesity (p-values from <0.0001 to 0.007); for example, the very-short-sleep–obesity relationship was strongest among Blacks/African-Americans, and the short-sleep–hypertension relationship was strongest among non-Hispanic Whites, Blacks/African-Americans, and non-Mexican Hispanics/Latinos.

Methods

  • Cross-sectional analysis of 2007–2008 US National Health and Nutrition Examination Survey (NHANES) adult respondents ages 18–80+ years with complete data (N=5,649), using census-weighted, nationally representative data.
  • Self-reported sleep duration was categorized as very short (<5 h), short (5–6 h), normal (7–8 h; reference), or long (≥9 h).
  • Outcomes were self-reported and objective hypertension, hyperlipidemia, diabetes, and obesity; analyses used chi-square tests and binary logistic regression with and without covariates, plus race/ethnicity interaction and stratified analyses in STATA/SE 12.

Limitations

  • The paper states that the cross-sectional design cannot infer causality; self-reported integer sleep duration may cause misclassification and attenuate associations; prospective diary and actigraphy would be better; extreme sleepers represent a small population subset; BMI does not capture central adiposity or some relevant factors, and residual confounding may exist.
  • The paper notes that race/ethnicity stratified analyses reduce statistical power, especially in less populous groups.
  • The text makes evident that self-reported versus objective outcome discrepancies may reflect recall bias, social desirability, state-dependent factors, or measurement error in the sleep duration item.

    Major

    The abstract says the association between short sleep and hypertension is strongest among non-Hispanic Whites, Blacks/African-Americans, and non-Mexican Hispanics/Latinos. The stratified results report no elevated outcomes among short sleepers in the first two groups and identify short-sleep hypertension among Mexican-Americans instead.

  • Objective-diabetes interaction is both significant and excluded

    Minor

    The results report a significant sleep-duration-by-race/ethnicity interaction for objective diabetes (p=0.0003), but the discussion says objective diabetes is the exception to race/ethnicity differences.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
