Hypothesis
This study aimed to clarify the relationship between sagittal spinal alignment and sleep disturbance.
Conclusion
Kyphosis in community-dwelling adults was found to be associated with sleep disturbance.
Supporting Evidence
- The percentage of sleep disturbance was 8.9% for non-kyphosis, 9.1% for moderate kyphosis, and 20.0% for severe kyphosis.
- Adjusted odds ratios were 1.16 for moderate kyphosis and 2.86 for severe kyphosis compared to non-kyphosis.
- Kyphosis is associated with sleep disturbances, particularly as its severity increases.
Takeaway
Older people with a curved spine (kyphosis) might have trouble sleeping well. The worse the curve, the more likely they are to have sleep problems.
Methodology
Data were drawn from the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) in 2010, assessing sleep disturbance through a self-administered questionnaire and measuring sagittal vertical axis (SVA) via radiographs.
Potential Biases
Some confounding factors, such as napping habits, may be intermediate factors rather than independent confounders.
Limitations
The study's radiological evaluation was limited to standing X-rays and did not assess spinal alignment during sleep, and self-reported sleep duration may not accurately reflect sleep disorders.
Participant Demographics
The mean age of participants was 69.7 years, with 61.7% being female.
Statistical Information
P-Value
1.16 for moderate kyphosis and 2.86 for severe kyphosis compared to non-kyphosis.
Confidence Interval
95% CI 0.65-2.05 for moderate kyphosis and 95% CI 1.13-7.26 for severe kyphosis.
Statistical Significance
