0864 Race/ethnicity And Sex-dependent Effects Of Metabolic Burden Across Different Age-categories On Trends In Self-reported Sleep Duration: Findings From The National Health Interview Survey, 2004-2013

Introduction

We examined race and sex-dependent effects of metabolic burden across different age-categories on trends in self-reported sleep duration for the U.S. non-institutionalized civilian population.

Methods

We analyzed data from the National Health Interview Survey (NHIS) adults aged 18-85 from 2004 to 2013 (N=258,158). Metabolic burden was characterized by obesity (BMI>30), dyslipidemia, diabetes, and hypertension morbidity burden levels. Racial/ethnic categories included non-Hispanic Whites (NHW), Blacks/African Americans (AAs) and Hispanics. Sleep duration within a 24-hour period on average was categorized as short sleep (≤ 6hrs), adequate sleep (7-8 hrs.), and long sleep (≥ 9hrs). Age was categorized as 18 - <26, 26 - <65 and 65 - 85. Adjusted multinomial logistic regression models stratified by race, sex and age-categories examined effects of metabolic burden on trends in self-reported sleep duration.

Results

The prevalence of short sleep duration was relatively stable from 2004-2012 for NHW and all females. However, AA and Hispanic males showed consistent increase in the rates of short sleepers beginning in 2007 through 2013 especially for ages 18 - <26, and 26 - <65 (P <.001 for trend). For all racial/ethnic categories, compared to individuals aged 18 - <26, individuals aged 26 - <65 were more likely to report short sleep (aOR: 1.55, 95% CI: 1.50-1.61) and individuals aged 65 - 85 were more likely to be long sleepers (aOR: 1.95, 95% CI: 1.86-2.05). Interestingly, the rate of short sleep increased as the metabolic burden increased (P <.001 for trend). This trend was more pronounced among AA and Hispanic males aged 65 - 85 with ≥ 2 metabolic conditions who were more likely to report short sleep (aOR: 1.77, 95% CI: 1.44-2.19 and aOR: 1.45, 95% CI: 1.17-1.93 respectively), compared to NHW males.

Conclusion

Increased metabolic burden among minority populations and especially in the elderly male, affect sleep and may have consequences for treating these populations.
