Nutritional assessment in rheumatoid arthritis

Area of Science:

• Rheumatology
• Nutritional Science
• Public Health

Background:

• Rheumatoid arthritis (RA) is a chronic inflammatory disease impacting joints and potentially leading to systemic complications.
• Nutritional status is crucial in managing RA, influencing disease activity, functional capacity, and overall patient outcomes.
• Assessing nutritional status in diverse RA patient populations is essential for targeted interventions.

Purpose of the Study:

• To evaluate the nutritional status of rheumatoid arthritis patients across different ethnic communities.
• To determine the prevalence of malnutrition using anthropometric measurements and serum albumin levels.
• To investigate the association between malnutrition and disease severity markers in RA patients.

Main Methods:

• Cross-sectional study involving 220 rheumatoid arthritis patients from three communities.
• Measurements included triceps skinfold (TSF) thickness, upper arm muscle circumference (UAMC), body mass index (BMI), percentage of ideal body weight (% IBW), and serum albumin.
• Malnutrition was defined by reduced anthropometric measurements and/or low serum albumin.

Main Results:

• Over 23% of patients (51/220) were identified as malnourished based on defined criteria.
• Malnourished patients demonstrated significantly higher mean erythrocyte sedimentation rates and more severe functional disability.
• Obesity (BMI > 30) was present in 10.5% of patients, with no significant differences in disease parameters compared to non-obese patients.

Conclusions:

• A significant proportion of rheumatoid arthritis patients exhibit malnutrition, correlating with increased disease activity and functional impairment.
• Nutritional assessment, incorporating anthropometric data and biochemical markers, is vital for identifying at-risk RA patients.
• Interventions addressing malnutrition may improve clinical outcomes and functional status in rheumatoid arthritis management.
