Bone mineral density is associated with composite dietary antioxidant index among US adults: results from NHANES
Authors' conclusion
CDAI serves as a comprehensive tool for evaluating the overall antioxidant capacity of antioxidants in diets. Additionally, our study shows a positive correlation between CDAI and BMD, which indicates that the combined intake of dietary antioxidants may help reduce the risk of osteoporosis in adults.
Study context
- Population
- US adults aged ≥20 years, NHANES (2005–2010, 2013–2014, 2017–2018); mean age 50.73 ± 16.65 years
- Participants
- 10,584 adults
- Exposure
- Quartiles of composite dietary antioxidant index vs first quartile
- Outcome
- Femoral BMD
Main finding
As reported in the abstract
Femoral BMD by CDAI quartile
- Second to fourth quartiles of composite dietary antioxidant index (CDAI) exhibited higher femoral bone mineral density (BMD) compared to the first quartile, after multivariate adjustment
- Positive correlation between CDAI and femoral BMD
- Multivariate linear regression
Observational data: associations, not effects.
Further findings
Individual dietary antioxidant intakes and femoral BMD
- Higher intakes of vitamin C, vitamin E, selenium, zinc and carotenoids associated with higher femoral BMD
