AB0519 PHYSICAL ACTIVITY AND OBESITY IN PATIENTS WITH ANKYLOSING SPONDYLITIS

Background:Ankylosing Spondylitis (AS) is associated with an increased cardiovascular risk. Obesity and limited activity in patients with AS may contribute to this cardiovascular risk.Objectives:We aimed to evaluate physical Activity and obesity in patients with AS.Methods:We conducted a cross-sectional observational study of 40 patients with AS, over a period of 3 months. We evaluated the level of physical activity using the IPAQ (International Physical Activity Questionnaire). We also measured body mass index (BMI), body fat percentage, waist circumference, hip circumference and their ratio in all patients.Results:The mean age of our population was 44±10 years. A male predominance was noted with a sex ratio =11.1. The mean ASDAS-CRP and BASDAI levels were 2.1±0.95 and 2.25±1.33. The mean of IPAQ was 3900 MET minutes per week, with a median of 3069 and extremes of 339 and 11000. 45.5% of patients had moderate physical activity and 20% had low activity.The mean BMI was 26.5 + 4.7 kg/m2. Twenty percent of patients were obese. The mean body fat percentage was 25% with a median of 23.7% and extremes of 8-46%. Forty-five percent of the patients had a high fat mass. The mean waist circumference was 95±13 cm, hip circumference 104±9.5 cm. The mean waist to hip ratio was 0.9±0.07. Thirty-seven percent of patients had a high waist to hip ratio. BMI and body fat percentage were negatively correlated with HDL level; (r=-0.365,p=0.024)and(r=-0.393,p=0.015) respectively.Conclusion:The majority of our patients have moderate or low levels of physical activity. The increase in BMI and fat mass appear to be associated with disturbance of the lipid balance, with low HDL values.Disclosure of Interests:None declared.
