Brief Summary
Ankylosing Spondylitis (AS) is a chronic inflammatory autoimmune disease. The aim of this study is to reveal the relationship between dietary intake, blood total antioxidant capacity and disease activity in individuals with AS. This study will include patients diagnosed with AS who applied to Ankara City Hospital Physical Therapy and Rehabilitation Hospital, and a control group that does not have AS. The sociodemographic characteristics and nutritional habits and 1-day physical activity status of individuals with AS and healthy persons will be recorded. Anthropometric measurements of all individuals (such as height length (cm) and body weight) will be taken. From the height and body weight measurements, the individuals body mass indexes will be calculated. All parts of the questionnaire for individuals included in the research will be filled in by the researcher through face-to-face interview technique. The disease activity score of the individuals in the case group will be evaluated by the physician. Serum biochemical parameters will be taken from the patient files. In the patient information system of the control group, above mentioned blood tests will be recorded from the examinations performed in the last 1 month. Serum total antioxidant and oxidant levels will be measured in a private laboratory with a tube (5 ml) of blood from all individuals. The parameters to be examined in blood samples are specific to the study and their cost will be covered by the researchers.

Outcome Measures
Primary Outcomes (3)
Dietary phytochemical index
Dietary phytochemical index is calculated from one day dietary record. Higher index is better.
Will be done only once on the first day after inclusion.
Total antioxidant and oxidant capacity
Higher total antioxidant capacity and lower oxidant capacity is better.
Blood samples will be obtained once on the first day after inclusion. Samples will be stored in -80 C medical refrigerator and analysis will be done after collection of all samples.
Ankylosing Spondylitis Disease Activity Score
Higher scores (\>2.1) mean active disease. Lower scores (\<1.3) mean inactive disease
Will be done only once on the first day after inclusion.
