Adult patients with AS diagnosis, fulfilling ASAS and modified New York criteria, treated for \u22653 months upon study inclusion according to clinical practice were included. The primary outcome was \u201cdisease control\u201d assessed by the percentage of patients in remission and low disease activity (BASDAI and ASDAS-CRP scores). HS was evaluated using the ASAS health index (ASAS-HI). Patients' responses and characteristics were analyzed by gender.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We analyzed 313 patients with AS, 237 (75.7%) males and 76 (24.3%) females.

According to ASDAS-CRP, 57.5% of patients were adequately controlled (ASDAS-ID +ASDAS-LDA); 138 (58.2%) males and 42 (55.3%) females. The mean (SD) ASDAS-CRP was 1.9 (1.1); being 1.9 (1.0) in males and 2.0 (1.1) in females. Overall, the impact of AS on HS was low to moderate [mean (SD) ASAS-HI 5.8 (4.4)]; being 5.5 (4.4) for males and 6.8 (4.2) for females (<jats:italic>p<\/jats:italic> = 0.02).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study showed a higher proportion of females with AS and active disease using the BASDAI definition.
