This cross-sectional study aimed to assess risk of fall and its contributing factors among older adults with chronic low back pain (CLBP). A random sample composed of 135 older adults from outpatient clinics at Zagazig University Hospitals. Risk of fall was measured by Fall Risk Assessment Scale. Contributing factors were identified by investigating the relationship of risk of fall with older adults’ characteristics. Study results revealed that 51.9% and 38.5% of older adults were at severe and moderate risk of fall, respectively. Statistically significant relations were found between risk of fall and age, female gender, rural residence, illiteracy, not working, insufficient income, chronic diseases, medication use, CLBP intensity, and numbers of fall. High prevalence of severe risk of fall and many contributing factors were identified among older adults with CLBP. So, Continuous fall risk assessment in CLBP patients with special concern for contributing factors assessed in study is recommended.
