Vitamin D and Inflammation in Healthy Women
Author Information
Author(s): Catherine A. Peterson, Mary E. Heffernan
Primary Institution: University of Missouri-Columbia
Hypothesis
Serum 25(OH)D concentrations would be inversely correlated with circulating concentrations of inflammatory markers.
Conclusion
Serum 25(OH)D status is inversely related to TNF-α concentrations in healthy women.
Supporting Evidence
- Women with regular UVB exposure had significantly higher serum 25(OH)D concentrations.
- An inverse relationship was found between serum 25(OH)D and TNF-α concentrations.
- The relationship remained significant after controlling for potential covariates.
Takeaway
This study found that women with higher vitamin D levels had lower levels of a substance that causes inflammation in the body.
Methodology
An observational study measuring serum 25(OH)D and inflammatory markers in healthy women aged 25-82.
Potential Biases
Women who tan regularly may have different health behaviors compared to non-tanners.
Limitations
The sample size was small and women with high UVB exposure were harder to recruit.
Participant Demographics
Caucasian females aged 25-82 years.
