Quantification of body composition alterations and identification of nutritional risk factors
among Rheumatoid Arthritis (RA) patients are clinically important. The objective of the study
was to determine selected nutritional and anthropometric parameters of patients with early RA.
A case control study was carried out at the Rheumatology Clinic of Colombo South Teaching
Hospital among 100 early RA patients (disease duration of RA < 4 years) and age, gender and
functional status matched healthy controls (n=100). Height, Weight, Waist Circumference
(WC), Hip Circumference and Serum Haemoglobin (Hb) levels of patients and controls were
assessed. The data were analyzed using the SPSS statistical package (version 20). Ethical
approval was obtained from the Ethics Review Committees of the Faculty of Medical Sciences,
University of Sri Jayewardenepura and Colombo South Teaching Hospital. A majority of the
patients were female (84%). Female RA patients had significantly high values of BMI
(27.1±4.4 kg m-2, p=0.003), WC (97.6±11.9 cm, p=0.000) and waist to hip ratio (0.99±0.10,
p=0.005) compared to female healthy controls (BMI- 25.1±3.5 kg m-2 , WC- 89.6±9.7 cm, and
waist to hip ratio - 0.93±0.06). Serum Hb levels of male (12.45± 1.18 g dl -1) RA patients were
significantly low (p=0.001) compared to healthy males (14.6±2.0 g dl -1). Anaemia was
observed among 48 % of total early RA patients and 4% of healthy controls. A majority of RA
patients had anemia and anthropometric impairment compared to healthy controls even from
the early stage of the disease.
