The relationship between insufficient sleep and self-rated health in a nationally representative sample

Reduced sleep has been found to be associated with increased risk of diabetes mellitus, hypertension, cardiovascular disease (CVD), and mortality. Self-rated health (SRH) has been shown to be a predictor of CVD and mortality. However, study of the association between insufficient sleep and SRH is limited. We examined participants 18 years of age (n=377, 160) from a representative, cross-sectional survey (2008 BRFSS). Self-reported insufficient sleep in the previous 30 days was categorized into six groups. The outcome was poor SRH. We calculated odds ratios ((OR) (95% confidence interval (CI)) of increasing categories of insufficient rest/sleep, taking zero days of insufficient sleep as the referent category. We found a positive association between increasing categories of insufficient sleep and poor SRH, independent of relevant covariates. In the multivariable-adjusted model, compared to 0 days insufficient sleep, the OR (95% CI) of poor SRH was 1.03 (0.97-1.10) for 1-6 days, 1.45 (1.34-1.57) for 7-13 days, 2.12 (1.97-2.27) for 14-20 days, 2.32 (2.09-2.58) for 21-29 days, and and 2.71 (2.53-2.90) for 30 days of insufficient sleep in the prior 30 days (P-trend 0.0001). In a nationally representative sample, increasing categories of insufficient sleep were associated with poor SRH.
