Abstract
Background: Knee osteoarthritis (KOA) is a leading cause of pain, disability, and
reduced quality of life worldwide. Despite evidence supporting the benefits of physical activity (PA) in managing KOA, many patients remain inactive. Identifying predictors of PA among this population is essential for developing tailored interventions.
Aim: This study investigated the predictors of physical activity levels among patients with knee osteoarthritis attending the University of Benin Teaching Hospital (UBTH).
Methods: A cross-sectional study was conducted with 36 participants diagnosed with KOA. Respondents were selected using purposive sampling. Data were collected on socio-demographic (age, sex, education), clinical (pain severity, duration of symptoms, comorbidities), and psychological variables (kinesiophobia, anxiety, depression). Instruments included the International Physical Activity Questionnaire–Short Form (IPAQ-SF), Tampa Scale for Kinesiophobia (TSK), and the Hospital Anxiety and Depression Scale (HADS). Descriptive and inferential statistics were applied, including Chi-square tests and ordinal logistic regression, with significance set at p<0.05.
Results: About half of the respondents (50%) had moderate PA, while smaller
proportions had low (11.1%) or high (38.9%) PA levels. Most patients reported high kinesiophobia, and mild symptoms of anxiety and depression. Anxiety showed a significant association with PA (P < 0.001), whereas socio-demographic, clinical, and other psychological factors were not significantly related. Regression analysis showed that none of the variables independently predicted PA levels.
Conclusion: Most patients with KOA were moderately active despite reporting high levels of kinesiophobia. Anxiety was related to PA but was not an independent predictor. Overall, PA appears to be influenced by multiple interacting factors, highlighting the need for holistic management strategies that address both physical and psychological aspects.
