Study Finds Common Blood Fat Linked to Rheumatoid Arthritis in Women
Triglycerides — the most common type of fat in the blood — may be a potential modifiable risk factor for rheumatoid arthritis (RA) in women, according to a new study.
New Delhi: Triglycerides — the most common type of fat in the blood — may be a potential modifiable risk factor for rheumatoid arthritis (RA) in women, according to a new study.

Rheumatoid Arthritis: A Chronic Autoimmune Condition
Rheumatoid arthritis is a chronic autoimmune disease predominantly affecting women. It is characterized by joint inflammation, pain, swelling, and in severe cases, joint deformities and functional disability.
The Role of Triglycerides in Inflammation
Triglycerides are important indicators of lipid metabolism and are known to be associated with inflammation and metabolic disorders — both contributing factors in the development of rheumatoid arthritis. However, the direct link between triglyceride levels and RA in women had remained uncertain until now.
Study Analyzed Data From Over 10,000 Women
Researchers from Suining Municipal Hospital of Traditional Chinese Medicine in Sichuan, China, analyzed data from 10,728 female participants between 1999 and 2018. Among them, 639 women were diagnosed with rheumatoid arthritis.
High Triglyceride Levels Significantly Linked to RA
The study, published in BMC Women’s Health, found a significant positive association between higher triglyceride levels and the prevalence of RA in women. Notably, this correlation remained strong even after adjusting for other possible influencing factors.
Monitoring Triglycerides Could Help in RA Management
“Our findings suggest that monitoring triglyceride levels in women with rheumatoid arthritis could be valuable,” said Chang-Mei Zeng, lead author of the study. “Elevated triglycerides may serve as a modifiable risk factor for the disease.”
Lifestyle and Medical Interventions May Reduce Risk
Zeng emphasized that targeting triglyceride levels through lifestyle changes or pharmacological treatments may help reduce inflammation and improve outcomes for RA patients.
Importance of Understanding Sex-Specific Factors
The researchers highlighted that the disease progression in women is often more complex, potentially involving hormonal fluctuations, immune response variations, and metabolic dysregulation. This underscores the need for sex-specific risk factor analysis for effective disease prevention and management.
Future Research Needed
The team called for further studies to explore the role of triglycerides in the pathogenesis of RA and to identify possible intervention pathways to reduce its impact in women.
