ObjectivesTo examine the association between self-reported sleep duration and osteoporosis in a national sample of the U.S. elderly population. DesignPopulation-based cross-sectional study. SettingFour-year National Health and Nutrition Examination Survey data from two survey cycles between 2005-06 and 2007-08. ParticipantsMen and women aged 50 and older with data in the surveys and medical examination data files (N=5,288). MeasurementsOsteoporosis diagnosis was based on bone mineral density measurement and self-report. Sleep duration was ascertained from the sleep survey. Simple and multiple logistic regression models were used to evaluate the association between these two factors. ResultsShorter sleep duration (<6hours) was found to be significantly associated with osteoporosis after adjusting for potential covariates (odds ratio (OR)=1.59, 95% confidence interval (CI)=1.07-2.37). After stratifying according to age group, this association remained significant (OR=1.80, 95% CI=1.20-2.68) only in the older age group (>65). ConclusionThese results underscore the possible linkage between sleep and osteoporosis and the need for additional research on this topic.
