Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: Epidemiological studies have found a high prevalence of obesity in patients with Psoriatic Arthritis (PsA). It was described the association between obesity and severity of psoriasis, but the relationship to the severity of PsA has been less studied.
Methods: PsA patients ≥18 years old according to CASPAR criteria, belonging to RAPSODIA (Registro de Artritis Psoriásica, IREP Argentina) cohort were included. Socio-demographic data, disease duration, type of onset and evolution of PsA, comorbidities, acute phase reactants and lipid profile were collected. Treatment data were collected through direct interview with the patient, complementing with medical history. 66 tender and 68 swollen joints count, enthesitis (MASES), presence of dactilitis, cutaneous (PASI) and nail involvement (PNSS) were evaluated. Disease activity (BASDAI), functional capacity (HAQ, BASFI), quality of life (DLQI, PsAQoL) questionnaires were completed. DAS28, DAPSA and MDA (Minimal Disease Activity) composite indexes were calculated. Visual analog scale (VAS) was used to grade severity of skin psoriasis, pain and patient and physician global assessment of disease activity. Height (cm), weight (kg) and blood pressure (mm Hg) were measured. BMI was calculated. Patients were classified according to WHO in normal (BMI 18.5-24.9), overweight (BMI 25-30) and obesity (BMI ≥30). Obesity was classified as grade I or mild (BMI 30-34.9), grade II or moderate (BMI 35-39.9) and grade III or severe (BMI ≥40). Statistical analysis: Descriptive statistics. T test and ANOVA. Chi2 and Fisher exact test. Multiple logistic regression (dependent variable: obesity). Univariate general linear model.
