The aim of the current study was to determine: the prevalence of low back pain (LBP) and associated disability; the frequency of consultation to general practice; whether there were differences in management by age. We conducted a cross-sectional population study in Aberdeen city and Cheshire County, UK. Participants were 15,272 persons aged 25 years and older. The 1-month period prevalence of LBP was 28.5%. It peaked at age 41-50 years, but at ages over 80 years was reported by 1 in 4 persons. Older persons were more likely to consult, and the prevalence of severe LBP continued to increase with age. Management by general practitioners differed by age of the patient. Older persons (> 70 vs ≤ 40 years) were more likely to only have been prescribed painkillers (odds ratio [OR] 1.74, 95% confidence interval [CI] 1.28-2.35) or only pain killers with other medications (OR 1.45, 95% CI 1.07-1.98). They were less likely to be prescribed physiotherapy or exercise (OR 0.63, 95% CI 0.46-0.85) or to be referred to a specialist (OR 0.77, 95% CI 0.57-1.04). Older persons were more likely to have previously received exercise therapy for pain, were less likely to be enthusiastic about receiving it now (P<0.0001), and were less likely to think it would result in improved symptoms (P<0.0001). It is important that older persons, who have the highest prevalence of LBP with disability and are most likely to consult, are receiving optimal pharmacological and nonpharmacological management.
Prevalence of disabling and non-disabling back pain was 6 and 23%, respectively. While prevalence of non-disabling back pain did not vary significantly across age (χ²trend : 0.90; P = 0.34), the prevalence of disabling back pain increased with age (χ²trend : 4.02; P = 0.04). New-onset disabling and non-disabling back pain at follow-up was 15 and 5%, respectively. Risk factors found to predict back pain onset at follow-up were: poor self-rated health (RR 3.8; 95% CI 1.8, 8.0); depressive symptoms (RR 2.2; 95% CI 1.3, 3.7); use of health or social services (RR 1.7; 95% CI 1.1, 2.7); and previous back pain (RR 2.1; 95% CI 1.2-3.5). From these, poor self-rated health, previous back pain and depressive symptoms were found to be independent predictors of pain onset. Markers of social networks were not associated with the reporting of back pain onset. Conclusion. The risk of disabling back pain rises in older age. Older adults with poor self-rated health, depressive symptoms, increased use of health and social services and a previous episode of back pain are at greater risk of reporting future back pain onset.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
