“…The prevalence rate of NLBP in our study was 13.1%, which is consistent with the findings of 10.0–49.0% in literature according to the definition of NLBP [5, 11–13, 36]. The validated pre-scoring system we developed based on ten factors had a high discriminative power at the bootstrap-corrected AUC of 0.861 and was strongly supported by the external validation (AUC of 0.821).…”

Background Nonspecific Low Back Pain (NLBP) is a common disease with a low cure rate and significant impact on the population. This study aimed to develop and validate a pre-scoring system for identifying the risk of suffering from NLBP among the general population in Guangzhou. Methods A total of 1439 eligible subjects were surveyed in Guangzhou by stratified random sampling and was divided randomly into the development dataset (69.6%) and validation dataset (30.4%) subsequently. Based on the development dataset, potential associated factors (average exercise times weekly, the intensity of daily work, etc.) with NLBP were tested by the sequential logistic regression, and a pre-scoring system was formulated with Sullivan’s method and graded afterward. The internal validity of the system was assessed by AUC and calibration plot, and the external validation was performed in the validation dataset. Results The prevalence rates of NLBP in the development dataset and the validation dataset were 12.97 and 13.27%, respectively. Age, BMI, average exercise times weekly, gender, educational level, the intensity of daily work, place of residence, monthly income, overall evaluation of health condition and physiology health were identified as significant factors. The total risk score ranged from 0 to 38, which was split into three risk grades: low risk (0 to 18), intermediate risk (19 to 22) and high risk (23 to 38). The pre-scoring system had an adequate calibration and a good discriminating ability with bootstrap-corrected AUC equaling 0.861 in the development dataset and 0.821 in the validation dataset. Conclusions A pre-scoring system that could help clinicians to assess the risk of NLBP in the general population was validated. Further validation of the system in a new population or prospective cohort study is suggested.

“…Participants were classified as having radiating LBP (pain that radiates below the knee) or non-specific LBP if they reported that their pain had lasted 7 days or more during the previous 12 months. Similar procedures have been applied also previously (Shiri et al, 2010b(Shiri et al, , 2013).…”

Background: Low back pain (LBP) is a prevalent problem and tends to be socio-economically patterned. Relatively little is known about life-course socio-economic circumstances as determinants of different types of LBP. Our aim was to examine whether childhood and adult socio-economic position and social mobility are associated with radiating and non-specific LBP and sciatica. Method: Data were derived from the Young Finns Study (n = 2231). Childhood socio-economic position was based on parental education, occupational class and family income at baseline in 1980. Data on own education and LBP outcomes were collected at the end of follow-up in 2007. Social mobility was based on parental and own education. Covariates were composed of age, parental body mass index and smoking. Results: Both childhood and own socio-economic position remained associated with radiating LBP and sciatica after adjustments. However, the associations varied by socio-economic indicator and gender. Stable lower socio-economic position and downward mobility were associated with radiating LBP. Conclusion: Childhood socio-economic circumstances affect the risk of radiating LBP and sciatica in adulthood. To prevent low back disorders, early socio-economic circumstances need to be considered alongside own socio-economic position.

“…It is a common symptom – reported prevalence rates ranging from 1% to 43% (Konstantinou and Dunn, 2008) – and may be accompanied by clinical findings suggestive of a herniated disc or nerve root irritation (Ropper and Zafonte, 2015) in “clinically verified sciatica”. In two Finnish cohort studies, the prevalence of lumbar radicular pain lasting longer than seven days during the past 12 months among participants who had previously been free from the symptom was 9% and 12% (Miranda et al, 2002; Shiri et al, 2010c), and that of lumbar radicular pain lasting longer than 30 days 3.0% and 3.4% (Miranda et al, 2002; Shiri et al, 2010c). The risk of lumbar radicular pain increased with age and did not differ between men and women (Miranda et al, 2002; Shiri et al, 2010c).…”

Background and objective: The role of leisure-time physical activity in sciatica is uncertain. This study aimed to assess the association of leisure-time physical activity with lumbar radicular pain and sciatica. Databases and data treatment: Literature searches were conducted in PubMed, Embase, Web of Science, Scopus, Google Scholar and ResearchGate databases from 1964 through August 2015. A randomeffects meta-analysis was performed, and heterogeneity and small-study bias were assessed. Results: Ten cohort (N = 82,024 participants), four case-control (N = 9350) and four cross-sectional (N = 10,046) studies qualified for meta-analysis. In comparison with no regular physical activity, high level of physical activity (≥4 times/week) was inversely associated with new onset of lumbar radicular pain or sciatica in a meta-analysis of prospective cohort studies [risk ratio (RR) = 0.88, 95% CI 0.78-0.99, I 2 = 0%, 7 studies, N = 78,065]. The association for moderate level of physical activity (1-3 times/week) was weaker (RR = 0.93, CI 0.82-1.05, I 2 = 0%, 6 studies, N = 69,049), and there was no association with physical activity for at least once/week (RR = 0.99, CI 0.86-1.13, 9 studies, N = 73,008). In contrast, a meta-analysis of cross-sectional studies showed a higher prevalence of lumbar radicular pain or sciatica in participants who exercised at least once/week [prevalence ratio (PR) = 1.29, CI 1.09-1.53, I 2 = 0%, 4 studies, N = 10,046], or 1-3 times/ week (PR = 1.34, CI 1.02-1.77, I 2 = 0%, N = 7631) than among inactive participants. There was no evidence of small-study bias. Conclusions: This meta-analysis suggests that moderate to high level of leisure physical activity may have a moderate protective effect against development of lumbar radicular pain. However, a large reduction in risk (>30%) seems unlikely. What does this review add: Leisure-time physical activity may reduce the risk of developing lumbar radicular pain.
