POS1465-HPR THE RELATIONSHIP BETWEEN SEDENTARY BEHAVIOR AND SLEEP IN RHEUMATOID ARTHRITIS: A CROSS-SECTIONAL STUDY

Background: Rheumatoid arthritis (RA) is a chronic, autoimmune inflammatory condition that affects 0.5% of the adult population worldwide (1). Sedentary behavior (SB) any waking characterized by an energy expenditure ≤1.5 METs (metabolic equivalent) and sitting or reclining posture, e.g. computer use (2) has negative impact on health in RA (3). Sleep important behavior, but sleep quality issue for people living with (4, 5). Poor associated low levels physical activity (4) however association between SB who have not been examined previously. Objectives: The aim this study was to investigate relationship RA. Methods: A cross-sectional conducted. Patients were recruited from rheumatology clinics large acute public hospital serving mix urban rural populations. Inclusion criteria diagnosis rheumatologist according American College Rheumatology age ≥ 18 ≤ 80 years; ability mobilize independently aided stick; understand written spoken English. Demographic data age, gender, disease duration medication recorded. Pain fatigue measured Visual Analogue Scale (VAS), anxiety depression assessed using Hospital Anxiety Depression (HADS), Pittsburgh Quality Index. ActivPAL4™ monitor, over 7-day wear period. Descriptive statistics calculated describe participant characteristics. Relationships clinical characteristics Pearson’s correlation coefficients regression analyses. Results: N=76 participants enrolled valid provided N=72 participants. Mean 61.5years (SD10.6) majority 63% (n = 47) female. Participant mean 17.8years (SD10.9). time 533.7 (SD100.1) minutes (8.9 hours per day/59.9% hours). score 7.2 (SD5.0) (Table 1). Correlation analysis found no significant variables. Regression demonstrated positive statistical associations body mass index (p-value=0.03846, R 2 0.05143), pain VAS (p-value=0.009261, 0.07987), HADS (p-value 0.009721, 0.08097) HADSD 0.01932, 0.0643).
