Resumen
Objectives To examine the association between self-reported sleep duration and osteoporosis in a national sample of the U.S. elderly population.
Design Population-based cross-sectional study.
Setting Four-year National Health and Nutrition Examination Survey data from two survey cycles between 2005–06 and 2007–08.
Participants Men and women aged 50 and older with data in the surveys and medical examination data files (N = 5,288).
Measurements Osteoporosis 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.
Results Shorter sleep duration (<6 hours) 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).
Conclusion These results underscore the possible linkage between sleep and osteoporosis and the need for additional research on this topic.
