Deciphering the relationship between age, body mass index, and knee osteoarthritis: a data-driven approach

Background Objectives were to assess the correlation between Western Ontario and McMaster university osteoarthritis index (WOMAC) score, age, and body mass index (BMI) in patients with osteoarthritis knee (OA).

Methods In this cross-sectional study, diagnosed cases of OA using the EULAR diagnostic criteria 2010 were enrolled. The WOMAC score was used to quantify pain, stiffness, and function in individuals with OA knee. Age, gender, and BMI were also recorded.

Results A total of 108 knee osteoarthritis patients were enrolled in the study, including 40 men and 68 women. The mean age of the patients was 55.92 years, and their average BMI was 27.24 kg/m2. The range of the WOMAC score was 3-12, with a mean of 29.3±1.03. The mean WOMAC scores for pain, stiffness, and functional disability score were 4.574 (1-4), 2.60 (0.12), and 22.20 (0.72) respectively.

Conclusions Functional status was compared in patients with OA knee, and there was a statistically significant relationship between the age of the patients and the degree of functional impairment caused by the OA knee. Additionally, it was shown that there was a significant negative correlation between age, BMI, and total WOMAC score.
