A research study that looked at whether certain genetic variations in how our bodies use vitamin D might affect high blood pressure during pregnancy has been retracted (officially taken back) by the journal that published it. This means the researchers or journal found problems with the study that made its results unreliable. While the original research seemed interesting, readers should know that this particular study’s findings can no longer be trusted. This is a good reminder that science is always checking itself to make sure information is accurate.

The Quick Take

  • What they studied: Whether specific genetic differences in how people’s bodies handle vitamin D could predict who might develop high blood pressure while pregnant
  • Who participated: The study compared pregnant women who developed high blood pressure with pregnant women who did not, but specific details about participant numbers and characteristics are not available in this retraction notice
  • Key finding: This study’s results have been retracted and should not be used because the journal or authors identified significant problems with how the research was conducted or reported
  • What it means for you: If you read about this study elsewhere, you should disregard its findings. Do not make any health decisions based on this research. Talk to your doctor about managing blood pressure during pregnancy using current, reliable evidence

The Research Details

The original study was designed as a case-control study, which is a type of research where scientists compare two groups of people: those who experienced a health problem (in this case, high blood pressure during pregnancy) and those who did not. Researchers then look backward to see if there were differences between the groups that might explain why one group developed the condition. In this case, they were looking at genetic differences in the vitamin D receptor, which is a protein that helps our bodies use vitamin D. However, because this study has been retracted, we cannot rely on how it was actually conducted or what methods were used.

Understanding genetic factors that might increase pregnancy complications could help doctors identify women at higher risk and provide better care. However, the retraction means this particular research did not meet the standards needed to contribute reliable information to medical knowledge.

This study has been formally retracted, which is the most serious quality concern possible. A retraction means the journal and/or authors determined there were significant problems—such as errors in data collection, analysis, reporting, or ethical concerns—that made the results unreliable and potentially misleading. Readers should not cite, reference, or use this study’s findings for any purpose.

What the Results Show

Because this study has been retracted, its primary findings are no longer considered valid and should not be reported or discussed as if they represent reliable scientific evidence. The retraction indicates that problems were discovered that undermined the credibility of the results. These problems could have involved how data was collected, how it was analyzed, how results were reported, or other methodological issues.

No secondary findings from this retracted study should be considered reliable or used to inform health decisions or further research.

While other research has explored the relationship between vitamin D and pregnancy health, this particular study cannot be included in comparisons or reviews of the scientific literature because it has been formally retracted.

The most critical limitation is that this entire study has been retracted due to identified problems. This means the study cannot be considered a reliable source of information. Readers should look to other, non-retracted research for information about vitamin D, genetics, and pregnancy complications.

The Bottom Line

Do not use this study’s findings to make any health decisions. If you are pregnant or planning to become pregnant and have concerns about high blood pressure, speak with your healthcare provider about evidence-based screening and management strategies. Current medical guidance should be based on studies that have not been retracted.

Pregnant women and those planning pregnancy should be aware of this retraction if they encountered this study. Healthcare providers should ensure they are not using retracted research in clinical decision-making. Researchers should be aware of this retraction when reviewing the scientific literature on vitamin D and pregnancy.

Not applicable—this study’s findings should not be acted upon

Want to Apply This Research?

  • Do not track or monitor health decisions based on this retracted study. Instead, work with your healthcare provider to track evidence-based health metrics relevant to your pregnancy
  • No behavior changes should be made based on this retracted research. Continue following your doctor’s recommendations for prenatal care and vitamin D intake based on current, reliable medical guidance
  • Focus on monitoring strategies recommended by your healthcare provider based on current, non-retracted scientific evidence and clinical guidelines

This study has been formally retracted and its findings are no longer considered reliable. Do not use this research to make health decisions. If you are pregnant or planning pregnancy and have concerns about high blood pressure or vitamin D levels, consult with your healthcare provider for evidence-based guidance. This retraction notice is provided for informational purposes only and does not constitute medical advice. Always rely on current, non-retracted scientific evidence and your doctor’s recommendations for prenatal health decisions.
