View abstract on PubMed
Summary
This summary is machine-generated.Higher serum folate levels are linked to an increased risk of developing allergic diseases in adults. Vitamin D levels showed no association with incident mouse sensitization in this study.
Area Of Science
- Allergy and Immunology
- Nutritional Science
- Occupational Health
Background
- Allergic diseases are a growing concern, with folic acid and vitamin D suspected as contributing factors.
- Previous research has not prospectively examined the link between these nutrients and adult-onset allergies.
Purpose Of The Study
- To investigate the association between serum folate and vitamin D levels and the development of new allergies in adult workers.
- Specifically, the study focused on incident mouse sensitization among new employees at a mouse research facility.
Main Methods
- A nested case-control study was conducted with new employees at The Jackson Laboratory.
- Serum folate and vitamin D levels were measured at baseline, and participants underwent allergen skin testing and questionnaires every six months.
- Multivariate analyses controlled for various potential confounders, including atopy, employment type, age, sex, smoking, and exposure levels.
Main Results
- Higher serum folate levels (intermediate and highest tertiles) were significantly associated with an increased odds of incident mouse sensitization.
- The odds ratios for incident sensitization were 10.5 and 5.6 for the intermediate and highest folate tertiles, respectively.
- Serum vitamin D levels did not demonstrate a significant association with incident mouse sensitization.
Conclusions
- Elevated serum folate levels may play a role in increasing the risk of developing allergic diseases in adulthood.
- These findings highlight the potential impact of nutritional status on adult-onset allergies and warrant further investigation.
