AB1356-HPR PHYSICAL ACTIVITY BEFORE, DURING AND AFTER PREGNANCY IN WOMEN WITH SPONDYLOARTHRITIS – DATA FROM REVNATUS

Background There are no known studies on physical activity (PA) in pregnancy for women with spondyloarthritis (SpA). PA is an essential and well-documented part of treatment for SpA [1]. The Norwegian Mother and Child Cohort Study (MoBa) found that established regular exercise routines pre-pregnancy was the strongest correlate of regular exercise during pregnancy [2]. A Swedish study of patients with SpA has shown that only 7 out of 10 patients with SpA meet the World Health Organization (WHO) recommendations of PA [3]. In MoBa 46.4% were regular exercisers (≥ 3 times a week) before pregnancy, while 25% were non-exercisers (≤ 3 times a month). At pregnancy week 17, 28% were regular exercisers, and 41% were non-exercisers.By pregnancy week 30, only 20% were still regular exercisers and 53% were non-exercisers [2]. Objectives To describe the level of PA before, during and after pregnancy for Norwegian women with SpA. Methods Women with SpA (ICD-10 M45, M46.1, M46.8 and M46.9) enrolled in the Norwegian nationwide quality register RevNatus that have self-report their level of PA, are included. Data from seven time points are presented. Results BASDAI - Bath Ankylosing Spondylitis Disease Activity Index, BMI body mass index, VAS visual analogue scale Conclusion During pregnancy, the percentage of women with SpA in the non-exercising group are increasing. The percentage of regular exercisers is lower 12 months after delivery than pre-pregnancy. Throughout the seven time points, 68 91% of the women with SpA do not fulfil the WHO recommendations for PA. PA should be an integral part of standard care throughout the course of disease for people with SpA and healthcare providers should take responsibility for promoting it and make necessary referrals to ensure that people with SPA receive appropriate PA-interventions [1].
