Low back pain (LBP) is a prevalent disease that affects all ages and is a symptom that induces immobility. Patients’ beliefs may influence LBP management, and adjusting detrimental beliefs is required to improve treatment outcomes. Our aim was to evaluate the prevalence of LBP within the Saudi population and beliefs regarding LBP, physical activity, rest, imaging, and medication. People with LBP were targeted with a questionnaire containing sections on demographic information and the validated Back Beliefs Questionnaire (BBQ), in addition to questions regarding imaging, physical activity, rest and medication. A total of 651 responses were received, 559 of them (86%) experienced LBP. The most common age group was those aged 18–21 (n = 221), 80% from females. The average BBQ score was 27.8 (SD = 5.58). The majority of the respondents held the following beliefs, which are contrary to the best available evidence: back pain must be rested (77.1%) and X-rays or scans are required to gain the best medical care for LBP (73.2%). The Saudi population holds unhelpful beliefs that may affect their quality of life. Healthcare professionals working with patients with LBP have an important role in changing detrimental beliefs and behaviors about the condition.

Background: The population sector of elders is progressively increasing, and it is estimated that it will reach almost one third of the total population in 2025. Large number of elders is suffering from knee osteoarthritis (OA) as the most prevalent rheumatic diseases worldwide. Recently there is a growing concern among researchers and health professionals regarding the impact of knee OA on elders and their quality of life (QOL). Objectives: To explore the impact of knee OA on QOL among Saudi elders aged between 60-70 years and to define which of the Short from survey (SF-36) domain (s) and which component, physical or mental, are mostly affected by this knee OA. In addition to study the presence of correlation between scores of SF-36 domains and components and the following factors; patient's age, gender, weight, height, body mass index (BMI), disease duration and severity, educational level, stability of the income source, income, housing type, housing ownership, and care giver. Subjects and Methods: This study was carried out during (December/ 2010 - March/ 2011). One hundred and twenty Saudi elders, (58, 48.3% male), aged between 60-70 years with mean± SD (64.5 ± 3.03) participated in this comparative study. Half of them had severe knee OA, as defined by knee society score (KSS), they were recruited from King Saud Medical City. The other half were without knee OA, were recruited from Prince Salman Social Center and the Saudi association for the Cooperative Retirees. Arabic version of Short Form -36 questionnaire was used to measure participants QOL domains scores as well as the overall scores of the physical and mental components of the questionnaire. Data collected were statistically treated and presented in tables. Results: Current study showed a better significant scores for Saudi elders without knee OA on all SF-36 domains (p = 0.0001). Calculating the patients' domain's scores as percentage from the maximum domain's scores which showed that, the mental health component of elders patients was more affected than physical health component and that role limitation due to emotional problems domain (RLEP) was the most affected domain (22.7%). Physical component showed positive correlation with income (r= 0.320, P= 0.013). While mental component showed negative correlation with disease duration (r = -0.341, P=0.008). Conclusion: Knee OA has negative impact on Saudi elders' QOL. Mental health component was more affected than physical health component. Consequently RLEP domain was the most affected domain. Patients' QOL was positively correlated to income and negatively correlated to disease duration.
