Fish Intake Linked to JIA?
Overview
A study presented at EULAR 2024 examined the association between maternal fish consumption and the risk of juvenile idiopathic arthritis (JIA) in children. Results indicated that high intake of lean and semi-oily fish was associated with JIA, while no significant links were found with oily fish or dietary mercury exposure.
Background
Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory joint disease in children. This study investigates the association between maternal diet during pregnancy and the risk of JIA.
Data Highlights
The study analyzed data from 73,819 mother-child pairs, identifying 218 cases of JIA. High fish consumption was defined as exceeding the 90th percentile for various fish categories, with high mercury intake classified as more than 20 μg per week.
Key Findings
- High consumption of lean and semi-oily fish during pregnancy was associated with increased odds of JIA in children.
- No significant association was found between total fish consumption or high mercury intake and JIA.
- The effect estimates for fish consumption were smaller compared to previous studies, such as a Swedish study from 2019.
- The study utilized data from the Norwegian Mother, Father, and Child Cohort Study, recruiting participants from 1999 to 2008.
- Maternal fish consumption was assessed using a food frequency questionnaire covering the first half of pregnancy.
Clinical Implications
The study's findings should be interpreted with caution, and healthcare providers should consider the complexities of dietary recommendations for pregnant women.
Conclusion
The study suggests an association between maternal fish intake and JIA risk, but causation cannot be established.
