SAT0087 ESTIMATED SLEEP DURATION AND CARDIOVASCULAR RISK IN RHEUMATOID ARTHRITIS: A CASE CONTROL STUDY

Background: Sleep is essential to human health and it is increasingly regarded as an important lifestyle behavior. The reduction in sleep duration have been linked to an increased risk of cardiovascular disease (CVD) and death in general population (1). Patients with rheumatoid arthritis (RA) have a higher risk of CVD and as in other pain conditions, commonly report poor sleep quality as well as feeling unrested and fatigued after sleep (2). This can be attributed to a lack of awareness of sleep hygiene. Objectives: To determine the prevalence of self-reported estimated duration of total daily sleep, daytime naps and quality of sleep of patients with RA and without rheumatic diseases and its association with cardiovascular risk factors. Methods: Observational, cross-sectional study. RA patients aged 40 to 75 years that fulfilled 2010 ACR/EULAR criteria and controls (without RA) were included. Sleep duration and quality, daytime naps and awareness of sleep hygiene were assessed with self-administered questionnaire. Descriptive analysis was done with frequencies (%), mean (SD), median (q25-q75). Comparisons with Chi-square, Mann-Whitney U test and Wilcoxon. Binary regression analysis was used to test association between estimated sleep duration ( Results: A total of 217 subjects were included. RA patients 93 (91.2%) vs 55 (47.8%) controls were female. Mean (SD) age was RA 56.68 (± 10.73) vs 57.27 (± 10.06) controls. Estimated sleep duration ( Conclusion: Patients with RA had a higher frequency of less estimated sleep time, this is associated with hypertension, risk of deaths and major cardiovascular events. Additionally, to inflammation and coexistence of CVD risk in RA. There was an absence of awareness of most of the individuals of sleep hygiene. Therefore, in clinical practice, assessment and education of sleep patterns may be of value in identifying higher risk individuals. An integrated care approach may contribute to the awareness of healthcare professionals to develop appropriate interventions. References: [1]Wang, C., et al (2019).
