Study Links PBDEs to Hormone Disruption in Male Sport-Fish Consumers
Sample size: 405
publication
Evidence: moderate
Author Information
Author(s): Dahl Richard
Hypothesis
Are PBDE exposures associated with changes in thyroid hormone levels in male sport-fish consumers?
Conclusion
The study found that PBDE exposure is associated with increased thyroglobulin antibodies and increased thyroxine in adult males.
Supporting Evidence
- PBDE concentrations were positively associated with increased T4 and reverse T3.
- An increase in thyroglobulin antibodies may indicate increased susceptibility to autoimmune thyroiditis.
- The study measured the effects of PBDEs on multiple hormones.
Takeaway
Men who eat a lot of fish from the Great Lakes may have higher levels of certain hormones because of chemicals called PBDEs found in the fish.
Methodology
The study analyzed PBDE exposure among 405 adult males who consumed sport fish, measuring hormone levels and other health data.
Limitations
The study's findings may not align with animal studies, suggesting further research is needed.
Participant Demographics
Adult males who consumed sport fish from the Great Lakes.
