Abstract
OBJECTIVES: To analyze if socioeconomic characteristics as lower education and lower family income are associated factors with the combination of pain catastrophizing and kinesiophobia in patients with knee osteoarthritis (KOA). METHODS: This cross-sectional study included 140 participants aged 40 years or older with KOA grades II and III. Based on the Pain Catastrophizing Scale (PCS) and the Tampa Scale of Kinesiophobia (TSK), four groups were identified: non-catastrophic/non-kinesiophobic (NC/NK), non-catastrophic/non-kinesiophobic (NC/K), catastrophic/non-kinesiophobic (C/NK), and catastrophic/kinesiophobic (C/K). Pain intensity was measured using the visual analog scale (VAS). The 30-s chair stand test was performed to access physical function. Sociodemographic characteristics included age, sex, years of formal education (0 to 11 and > 11), and family income (up to 2 minimum wages and > 2). Multinomial regression analysis adjusted for age, radiographic severity, physical function, and pain intensity was used to determine the association between lower education and lower family income with the combination of pain catastrophizing and kinesiophobia. RESULTS: Only lower education was independently associated with the combination of pain catastrophizing and kinesiophobia (OR = 3.96 CI 95% 1.01-15.51). CONCLUSIONS: Lower education but not lower family income was an important associated factor with the combination of pain catastrophizing and kinesiophobia in individuals with knee osteoarthritis. Thus, physician and physical therapist must pay attention on this important socioeconomic characteristic while conducting the treatment, since specific strategies of approach could be necessary for those patients. Key points • Lower education is an important associated factor with the combination of pain catastrophizing and kinesiophobia in individuals with knee osteoarthritis. • Physician and physical therapist must pay attention on patients schooling while conducting the treatment.
