Associations of dietary oxidative balance score with femur osteoporosis in postmenopausal women: data from the National Health and Nutrition Examination Survey
Authors' conclusion
The present study indicated that postmenopausal women with a higher DOBS have a lower risk of femur osteoporosis.
Study context
- Population
- American postmenopausal women, NHANES
- Participants
- 3,043 women
- Exposure
- Highest vs first tertile of dietary oxidative balance score
- Outcome
- Risk of femur osteoporosis
Methodological detailsNHANES data, weighted multivariate linear regression, weighted logistic regression, smooth curve fitting, weighted generalized additive model
- NHANES data
- Weighted multivariate linear regression
- Weighted logistic regression
- Smooth curve fitting
- Weighted generalized additive model
Main finding
As reported in the abstract
Osteoporosis risk
Highest tertile of DOBS vs First tertile of DOBSOdds ratio (95% CI)
Age <70
0.418(0.334–0.522)
Age ≥70
0.632(0.506–0.790)
Observational data: associations, not effects.
Further findings
Femur BMD
- Positive correlation between dietary oxidative balance score (DOBS) and femur BMD after adjusting for all covariates
Smooth curve fitting (SCF) and generalized additive model (GAM) models
- Similar trends observed
