Background: Ankylosing spondylitis (AS) is a chronic inflammatory disease of the axial spine that can manifest with various clinical signs and symptoms. Chronic back pain and progressive spinal stiffness are the most common features of this disease. It is an autoimmune disease which also leads to the involvement of skeletal, cardiac, nervous tissues, and other systemic organs.
Aim and Objectives: This study was conducted to assess the correlation between the Bath AS Disease Activity Index (BASDAI) score/visual analog scale (VAS) and various age groups in the patients suffering with AS using standard questionnaire.
Materials and Methods: Forty-eight AS patients having BASDAI scores of ≥4 were included in this study. The height and weight were taken and responses to the standard questionnaire were recorded. BASDAI Score, body mass index (BMI), and VAS were computed. The patients with history of chronic diseases such as hyper/hypothyroidism, diabetes mellitus, and hypertension or the use of any medication such as α/β blockers, calcium channel blockers, and antiepileptics were excluded from the study.
Results: The patients were divided into six different age groups, i.e., 15–20 years, 21–25 years, 26–30 years, 31–35 years, 36–40 years, and 41–45 years. The mean ± SEM values of the BASDAI score in various age groups were 6.8 ± 0.34, 6.3 ± 0.33, 6.2 ± 0.26, 7.1 ± 0.41, 6.5 ± 0.30, and 5.8 ± 0.48, respectively. The mean ± SEM values of VAS are shown in relation to the various age groups, i.e., 15–20 years, 21–25 years, 26–30 years, 31–35 years, 36–40 years, and 41–45 years and the values were 6.88 ± 0.312, 6.58 ± 0.22, 6.55 ± 0.66, 6.00 ± 0.23, 6.72 ± 0.25, and 6.0 ± 0.50, respectively.
Conclusion: This study indicates that in the young age group, patients BASDAI score is higher and BMI is lower, and in the older age group, patients BASDAI score is lower and BMI is higher than each other indicating higher disease activity in the younger patients than older patients. An inverse correlation between VAS and age further substantiates our previous finding.
