Prevalence Of Chronic Low Back Pain Research Articles

Occupational low back pain among Japanese caregivers: A large-scale cross-sectional study.

Caregivers in Japan experience a high prevalence of low back pain (LBP), with age, sex, individual pain experiences, and central sensitization symptoms potentially influencing its chronic progression. To determine the prevalence of LBP among caregivers, as well as its relation to age and sex, and explore work status, psychological factors, and central sensitization symptoms as contributing factors to chronic LBP (CLBP). A large-scale cross-sectional survey was conducted among 1214 caregivers in 35 geriatric healthcare facilities. The survey assessed LBP and CLBP prevalence, work status, psychological factors, and central sensitization-related symptoms. Multivariate logistic regression analysis was used to identify factors influencing CLBP. Among 936 valid respondents, the LBP prevalence was 69.2%. No significant sex differences were found in the prevalence of LBP and CLBP. Old age, higher pain severity, and severe symptoms related to central sensitization increased the risk of CLBP. However, work status and psychological factors did not significantly contribute to CLBP. There is a high prevalence of LBP among caregivers, age and individual pain experience significantly impact CLBP. These findings emphasize the need for therapeutic strategies to manage pain intensity, especially in the acute phase, to prevent the progression to chronicity.

Trunk muscle dysfunction in patients with myotonic dystrophy type 2 and its contribution to chronic low back pain.

Myotonic dystrophy type 2 (MD2) presents with a varied manifestation. Even though the myopathy in these patients is more widespread, axial musculature involvement is one of the most prominent conditions. MD2 patients also often report chronic low back pain (CLBP). The purpose of this study was to evaluate trunk muscle function, including respiratory muscles, in patients with MD2 and to compare it with healthy controls, to determine the occurrence of CLBP in patients with MD2, and to assess whether trunk muscle dysfunction increases the risk of CLBP in these patients. We enrolled 40 MD2 patients (age range 23 to 76 years, 26 women). A comprehensive battery of tests was used to evaluate trunk muscle function. The tests consisted of quantitative muscle strength testing of low back extensor muscles and respiratory muscles and the assessment of trunk muscle endurance. A neurological evaluation contained procedures assessing the distribution of muscle weakness, myotonia, and pain, and used questionnaires focused on these items and on disability, depression, and physical activity. The results of this study suggest that patients with MD2 show significant dysfunction of the trunk muscles, including the respiratory muscles, expressed by decreased muscle strength and endurance. The prevalence of CLBP in patients with MD2 was 52.5%. Based on our analysis, the only independent significant risk factor for CLBP in these patients was maximal isometric lower back extensor strength in a prone position ≤ 15.8 kg (OR = 37.3). Other possible risk factors were severity of myotonia and reduced physical activity. Outcomes of this study highlighted the presence of axial muscle dysfunction, respiratory muscle weakness, and frequent occurrence of CLBP together with its risk factors in patients with MD2. We believe that the findings of this study may help in management and prevention programs for patients with MD2.

Identifying Risk Factors and Health Concerns Associated With Chronic Low Back Pain Among Northern Indians: A Community-based Study

BACKGROUND: Chronic low back pain (CLBP) is a common and significant cause of disability globally. In their lifetime, 70% to 80% of adults will have low back discomfort at some point. Even though CLBP is a very disabling disorder, information about its prevalence and associated factors is sparse in the literature OBJECTIVES: We aimed to determine the prevalence of CLBP and its risk factors among an adult population, as well as related health concerns and health-seeking behaviors. STUDY DESIGN: Cross-sectional study. SETTING: A tertiary care setting in Chandigarh, India from November 2017 through February 2020. METHODS: Adults of either gender who provided informed consent were included in the study. Sociodemographic and CLBP awareness data were collected using a standard questionnaire. Prevalence was expressed as proportion of sample, with 95% CI. For categorical and quantitative data, the chi squared and independent t test were utilized. Logistic regression was applied to identify significant risk variables and outcomes. A P value of <= 0.05 was considered significant. RESULTS: A total of 2,847 patients were enrolled, with a mean (SD) age of 38 (14) years; 61% of them were men. These patients had a CLBP lifetime prevalence of 16% (95% CI, 15-17; 457/2,847). In addition, 62% (285/457) of these patients visited their doctor/physician more than 10 times and 23% (103/457) sought the advice of 2 physicians to treat their CLBP. Increasing age (odds ratio[OR], 1.040, 95% CI, 1.032-1.049; P < 0.001), being underweight (OR, 3.315; 95% CI, 1.494-7.359; P < 0.003) and increasing pain frequency (OR, 1.616; 95% CI, 1.139–2.293; P < 0.007) were identified as potential CLBP risks. LIMITATIONS: The study was carried out in a single tertiary hospital in northern India; hence its results cannot be extrapolated. Also, we were unable to categorize CLBP based on how severe the symptoms were, such as complaint-only or debilitating. CONCLUSION: An effective, supervised program addressing the younger productive population to maintain a healthy weight, give up smoking, and encourage an active lifestyle should be implemented. KEY WORDS: Chronic low back pain, prevalence, health concerns, risk factors, public health

Low Back Pain and the Social Determinants of Health: A Systematic Review and Narrative Synthesis: A Critically Appraised Paper

Focused Clinical Question: In adult patients with persistent low back pain, what relationship do social determinants of health have on pain frequency or severity? Bottom Line: This systematic review identified several particular social risk factors (including education status, socioeconomic status, and occupational factors) that are consistently associated with adverse low back pain outcomes. In addition, the analysis of the population-representative (cross-sectional) studies demonstrated support for important associations between specific social determinants of health, such as low socioeconomic status/income status and employment status and chronic low back pain prevalence.

Chronic low back pain prevalence in Federal Highway Police Officers: A cross-sectional study.

Police officers are exposed to specific occupational tasks, which require lifting, trunk flexion and rotation, carrying weight, and frequent standing periods, which may be associated with an increased risk of experiencing low back pain (LBP). To describe the prevalence and intensity of chronic LBP (CLBP) in Brazilian Federal Highway Police officers (FHPO) from the Rio Grande do Sul state and evaluate its associated factors. A total of 208 FHPOs participated in this study. The participants answered an electronic questionnaire containing sociodemographic, behavioral, and occupational questions, and CLBP history. Data analysis comprises descriptive statistics and Poisson regression models. Most of the FHPO were male, aged 41 or more, lived with a partner and were physically active. Sixty-seven percent of FHPO had CLBP, and the median pain intensity was 3.0 (IQR = 0- 5). Participants who lived with a partner were less likely to report CLBP (PR = 0.80; 95% CI = 0.64; 0.99). On the other hand, those who worked as FHPO for more than 11 years were more likely to report CLPB (PR = 1.32; 95% CI = 1.06; 1.63), and high pain intensity (β= 0.95; 95% CI = 0.19; 1.71). The high CLBP prevalence among FHPO from Rio Grande do Sul state indicates a need to highlight the importance for police organizations to promote CLBP prevention and implement workplace management programs.

Prevalence of chronic low back pain and its associated factors in the general population of South Korea: a cross-sectional study using the National Health and Nutrition Examination Surveys

BackgroundMany factors associated with chronic low back pain (CLBP) have been proposed, including individual, psychosocial, and physical factors. However, these associated factors are still controversial.Purpose(1) To determine the prevalence of CLBP and (2) to analyze factors associated with CLBP in the general population using a nationally representative sample of South Koreans.Study designCross-sectional study.Patient sampleData from versions IV-1, -2, and -3 of the Korea National Health and Nutrition Examination Survey (KNHANES), which were performed in 2007, 2008, and 2009, respectively (n = 24,871).Outcome measuresMultiple logistic regression analysis was performed to determine the association between several factors (age, gender, alcohol consumption, household income, education level, mid-intensity physical activity, depressive symptoms, vitamin D level, and comorbidities [stroke, ischemic heart disease, knee osteoarthritis, asthma, COPD, cancer history]) and CLBP.MethodsCLBP status was surveyed using a self-reported questionnaire. Demographic, socioeconomic status, comorbidities, and other factors were evaluated from health questionnaires, health and physical examinations, and laboratory tests. To analyze the association between these factors and CLBP, we used multiple logistic regression analysis.ResultsData from 17,038 participants were included in the final analysis, including 2,693 with CLBP and 14,345 without. The prevalence of CLBP was 15.8% in South Korean subjects, with a prevalence of 11.8% in men and 24.5% in women. After regression analysis, we found advanced age, female gender, mid-intensity physical activity, depressive symptoms, stroke, ischemic heart disease, knee arthritis, asthma, COPD, and cancer history were positively associated with CLBP. In contrast, alcohol consumption ≥ 1 drink per month, increased household income, higher education level, and vitamin D insufficiency were negatively associated with CLBP.ConclusionsOur study showed that CLBP was most common in the elderly and women in the general South Korean population. Several individual, socioeconomic, lifestyle, and health-related factors were associated with CLBP. These results demonstrate the influence of these factors on CLBP in the general population and suggest that consideration of these factors may improve the management of CLBP.

Potential mechanisms underlying the accelerated cognitive decline in people with chronic low back pain: A scoping review.

A growing body of evidence has shown that people with chronic low back pain (CLBP) demonstrate significantly greater declines in multiple cognitive domains than people who do not have CLBP. Given the high prevalence of CLBP in the ever-growing aging population that may be more vulnerable to cognitive decline, it is important to understand the mechanisms underlying the accelerated cognitive decline observed in this population, so that proper preventive or treatment approaches can be developed and implemented. The current scoping review summarizes what is known regarding the potential mechanisms underlying suboptimal cognitive performance and cognitive decline in people with CLBP and discusses future research directions. Five potential mechanisms were identified based on the findings from 34 included studies: (1) altered activity in the cortex and neural networks; (2) grey matter atrophy; (3) microglial activation and neuroinflammation; (4) comorbidities associated with CLBP; and (5) gut microbiota dysbiosis. Future studies should deepen the understanding of mechanisms underlying this association so that proper prevention and treatment strategies can be developed.

Revisiting chronic low back pain: evidence that it is not non-specific.

There is a common symptom pattern with most chronic low back pain (CLBP), suggesting that there is a common underlying etiology, belying the term "nonspecific." Many studies of CLBP and its treatment have been conducted with the assumption of nonspecificity, and as a result, treatment has not been focused, thus there has not been a significant change in CLBP prevalence over the past several decades. It is the thesis of this study to show that there is an underlying, specific cause of CLBP and that the presumption that CLBP is nonspecific is misdirected. The lumbosacropelvic (LSP) region, including the sacroiliac joint (SIJ), is part of a neuromusculoskeletal (NMSK) feedback system, and it is proposed here that CLBP is the result of a change in the feedback (afferent) aspect in that system. The objectives of this study are to show that CLBP presents as a pattern of symptoms that actually represents the final common pathway for a dysfunctional LSP joint system. Rather than being "nonspecific," the majority of CLBP has an underlying cause that is quite specific and predictable. A total of 252 patients were seen for CLBP, 67% of whom were diagnosed with an SIJ dysfunction. The presence of pain was recorded from seven structures most closely associated with CLBP. The conditional probabilities of having each pain generator given a SIJ dysfunction and an SIJ dysfunction given the presence of the pain generator were estimated, and associations were analyzed utilizing chi-square tests. Phi coefficients and odds ratios were utilized to quantify the strength of the association. The multivariable logistic regression model was fit to relate thepresence or absence of the SIJ dysfunction to the seven pain generators. The associations between SIJ dysfunction and each pain generator were statistically significant. Phi coefficients indicated moderate strengths of these bivariate associations. Iliolumbar ligament (ILL) and psoas muscle (PSM) were significant predictors of SIJ dysfunction in the multivariable model. Seven pain generators had a strong association with SIJ dysfunction. This empirical clinical evidence supports our hypothesis that LSP system dysfunction, as evidenced by SIJ dysfunction, is a common source of symptom patterning associated with CLBP and is most likely the causal element. This is evidence that most CLBP is not "nonspecific" but rather the result of changes made by the NMSK control system for the LSP region.

Prevalence and biopsychosocial factors associated with chronic low back pain in urban and rural communities in Western Africa: a population-based door-to-door survey in Benin.

PurposeThis study aimed to assess the prevalence of chronic low back pain (CLBP) and related biopsychosocial factors in urban and rural communities in Benin. MethodsThis is a population-based observational cross-sectional survey. An interviewer-administered electronic questionnaire was used to collect information on demographic, socio-economic, behavioral, and psychological factors relating to CLBP risk factors and medical history of participants. The numeric pain rating scale and the Beck Depression Inventory were used to assess pain intensity and the level of depression, respectively. Bivariate analyses were performed to investigate the association between sociodemographic, behavioral, and psychological factors and CLBP. Sequential multiple regression analyses were subsequently performed to predict the occurrence of CLBP.ResultsA total of 4320 participants, with a mean age ± SD of 32.9 ± 13.1 years, of which 40.7% were females and 50.1% from an urban area, were enrolled in the study. We found a global prevalence rate of CLBP of 35.5% [95% CI 34.1–36.9%]. The prevalence in urban areas was 30.68% [95% CI 28.9–32.8%]) while 40.2% was found in rural areas [95% CI 38.1–42.2%]). Age (p < 0.001), level of education (p = 0.046), marital status (p < 0.001), working status (p < 0.003), tobacco use (p < 0.016) and regular physical activity (p < 0.011) were associated with CLBP. In urban areas, only the level of education was able to predict the prevalence of CLBP (R2 = 61%). In rural areas, CLBP was predicted by age, marital and working status (R2 = 89%).ConclusionsThis study showed a high prevalence of CLBP among urban and rural communities in Benin. Age, level of education, marital status, and working status were significantly associated with CLBP in Benin.

Does sleep quality modify the relationship between common mental disorders and chronic low back pain in adult women?

ObjectiveThis study explored the association between common mental disorders (CMD) and chronic low back pain (CLBP) in women, while considering poor sleep quality as a potential effect modifier of this relationship. MethodsA cross-sectional population-based study was conducted with a representative sample of 1068 women (age 20–69 years) living in the urban area of São Leopoldo, RS, Brazil. CLBP was defined as pain lasting for ≥3 months; CMD was assessed using the Self-Reporting Questionnaire (SRQ-20; score ≥8); poor sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI; score ≥5). Poisson regression with robust variance was used to estimate the prevalence ratios (PR) with 95% confidence intervals (CI). ResultsThe prevalence of CLBP, CMD, and poor sleep quality was 46.8% (95% CI: 43.8–49.8), 33.5% (95% CI: 30.3–36.3), and 42.3% (95% CI: 39.3–45.2), respectively. Poor sleep quality was a significant modifier of the association between CMD and CLBP. Among women with poor sleep quality, women with CMD had a 48% higher probability of having CLBP compared to women without CMD and after adjustment for confounders (PR = 1.48; 95% CI: 1.23–1.77; p < 0.001). The relationship between CMD and CLBP was not statistically significant in women with good sleep quality. ConclusionsThis study revealed a significant relationship between CMD and CLBP, wherein poor sleep quality acted as an effect modifier. Women with CMD and poor sleep quality were more vulnerable to CLBP.

Major dietary patterns in relation to chronic low back pain; a cross-sectional study from RaNCD cohort

BackgroundChronic low back pain (LBP) is the most common musculoskeletal pain that affects a person’s daily activities. This present study aimed at evaluating the relationship between major dietary pattern and Chronic LBP.MethodsThis cross-sectional analysis was examined 7686 Kurdish adults. The RaNCD cohort study physician diagnosed chronic LBP. Dietary patterns were derived using principal component analysis. The three identified dietary patterns derived were named: 1) the vegetarian diet included vegetables, whole grain, legumes, nuts, olive, vegetable oil, fruits, and fruit juice; 2) high protein diet related to higher adherence to red and white meat, legumes, nuts, and egg; and 3) energy-dense diet characterized with higher intake of salt, sweet, dessert, hydrogenated fat, soft drink, refined grain, tea, and coffee. Dietary pattern scores were divided into tertiles. Binary logistic regression in crude, adjusted odds ratios (OR) and 95% confidence intervals (CI) were used to determine this association.ResultsTwenty-two per cent of participants had chronic LBP. Higher adherence to high protein dietary pattern was inversely associated with chronic LBP in crude (OR: 0.79, 95% CI: 0.69–0.9) and adjusted model (for age, sex, smoking, drinking, diabetes, physical activity, body mass index, and waist circumference) (OR: 0.84, 95% CI: 0.72–0.97). In addition, after controlling for the mentioned potential confounders, participants in the highest category of energy dense diet were positively associated with chronic LBP compared with those in the lowest category (OR: 1.13, 95% CI: 1.01–1.32).ConclusionsHigher adherence to the high protein diet was inversely related to chronic LBP prevalence. In addition, we found that following energy dense diet was positively associated with chronic LBP.

A Scoping Review on the Epidemiology of Chronic Low Back Pain among Adults in Sub-Saharan Africa.

Background: The global burden of chronic low back pain (CLBP) is a major concern in public health. Several CLBP epidemiological studies have been conducted in high-income-countries (HICs) with little known in low-and-middle-income-countries (LMICs) due to other competing priorities of communicable diseases. The extrapolation of results of studies from HICs for use in LMICs is difficult due to differences in social norms, healthcare systems, and legislations, yet there is urgent need to address this growing burden. It is against this backdrop that we conducted this review to map the current evidence on the distribution of CLBP in Sub-Saharan Africa (SSA). Methods: A comprehensive literature search was conducted from the following databases: PubMed, Google Scholar, Science Direct databases, World Health Organizations library databases, EMBASE, EBSCOhost by searching the following databases within the platform; academic search complete, CINAHL with full text, health sources: nursing/academic and MEDLINE. The title, abstract and the full text screening phases were performed by two independent reviewers with the third reviewer employed to adjudicate discrepancies. The reference list of all included articles was also searched for eligible articles. This scoping review was reported in accordance with the PRISMA extension for scoping reviews (PRISMA-ScR): checklist and explanation, as well as guided by Arksey and O’Malley’s scoping review framework. A thematic content analysis was used to give a narrative account of the review. Results: The electronic search strategy retrieved 21,189 articles. Title/abstract and full text screening only identified 11 articles, which were included in this review. The prevalence of CLBP among the general population ranged from 18.1% to 28.2% and from 22.2% to 59.1% among LBP patients. The prevalence of occupation based CLBP ranged from 30.1% to 55.5%. Identified risk factors for CLBP are multifactorial and included biomechanical, psychological, socioeconomic and lifestyle factors, with psychosocial factors playing a significant role. Hypertension, diabetes mellitus, peptic ulcer disease were the most common comorbidities identified. CLBP disability was significantly associated with psychosocial factors. The management of CLBP in primary care follows the traditional biomedical paradigm and primarily involves pain medication and inconsistent with guidelines. Conclusions: There are limited epidemiological data on CLBP in SSA, however, this study concluded that the prevalence and risk factors of CLBP in SSA are comparable to reports in HICs. Considering the projected increase in the burden of CLBP in LMICs extensive research effort is needed to close this knowledge gap.

Management of chronic low back pain and the impact on patients' personal and professional lives: Results from an international patient survey.

ObjectiveThe objective of this study was to investigate the impact of chronic low back pain (CLBP) on patients’ personal and professional lives, and management strategies applied to treat CLBP.MethodsA 60‐question survey was developed, and respondents from 16 countries with a self‐reported physician's diagnosis of CLBP were recruited via an online market research survey panel. Respondents were stratified as having mild, moderate, or severe pain. Target sample sizes per country and for pain severity were set. Data were weighted according to the known population and prevalence of CLBP in each country and the number of respondents from that country.ResultsResults from 9642 CLBP patients indicated that almost a quarter of patients with severe CLBP report a psychological comorbidity. Prescription pain medications were more commonly used by patients with severe CLBP (56%) than those with mild (20%) or moderate (34%) CLBP. Among those with severe CLBP who had been prescribed pain medication, 58% were prescribed opioids, with 1 in 4 patients using opioids for more than 5 years. Patients were primarily managed by general practitioners/primary care physicians, physiotherapists, neurologists, or orthopedic surgeons. CLBP negatively impacted patients’ daily activities, social lives, and work productivity.ConclusionChronic low back pain has pronounced effects on patients’ personal relationships, ability to work, and daily living. Almost 1 in four patients with severe CLBP reported a psychological comorbidity. Adherence to guidelines appears inconsistent, which is noteworthy as a substantial subgroup of patients with severe CLBP had been prescribed opioid medication for more than 5 years. Improved education is required to support healthcare professionals (HCPs) in identifying and understanding the complex biopsychosocial needs of CLBP patients to optimize pain management and to encourage referral of CLBP patients to physiotherapists and psychologists.

Does the risk of chronic low back pain depend on age at menarche or menopause? A population-based cross-sectional and cohort study: the Trøndelag Health Study

ObjectiveIn most population-based studies of low back pain (LBP), women have a higher risk than men, possibly reflecting hormonal influences. The aim of this study was to explore associations between...

Mediational Analysis of Yoga's Effect on Chronic Low-Back Pain in Veterans: What Factors Really Matter?

Considerable evidence supports yoga as a treatment for chronic low-back pain (CLBP), yet more research is needed on the mechanisms of yoga. Yoga may be particularly helpful for military veteran populations, where there is a high prevalence of CLBP due to intensive training requirements. Our objective was to examine possible mechanisms by which yoga reduced disability in a clinical trial of yoga for veterans with CLBP. Using data from a prior randomized controlled trial, we used mediation analysis to examine factors that may mediate or influence the effects of yoga on disability over time. The 12-week yoga intervention study measured outcomes at baseline, 6 weeks, 12 weeks, and 6 months. Fatigue and pain were the variables that met all statistical criteria for mediation of the effect of yoga on disability. The total effect of yoga on disability was significant (β = -2.28; 95% CI -3.93 to -0.64), and this consisted of a direct effect of yoga (β = -1.40; 95% CI -3.02 to 0.25) and a statistically significant indirect effect (β = -0.88, 95% CI -1.91 to -0.15) that was mediated by pain and fatigue. The indirect effect accounted for 38% of yoga's effect on back-pain disability. Fatigue and pain were not significant as individual mediators. The other mediators-self-efficacy, spinal range of motion, grip strength, core strength, and balance-did not meet published criteria for mediation. Our results suggest that in veterans with CLBP, yoga may reduce pain and fatigue and contribute to reductions in disability. Although pain may be an expected precursor of disability, the finding that fatigue mediates the relationship between a mind-body intervention like yoga and disability appears novel. Fatigue should be measured more widely in yoga research and considered when designing interventions for specific populations such as military veterans with chronic pain.

Meloxicam efficacy and safety in treatment of pain syndromes of different localization according to domestic studies

More than 500 million people worldwide suffer from osteoarthritis (OA). Neck and low back pain (LBP) is one of the most common reasons for visiting a general practitioner to receive primary medical care in different countries. The prevalence of chronic LBP varies from 4% to 20%, and increases linearly from the third decade to 60 years, and stabilizes in the seventh decade of life. According to the latest published clinical guidelines of the Russian Association for the Study of Pain, nonsteroidal anti-inflammatory drugs (NSAIDs) are used in minimally effective doses and a short course to relieve acute musculoskeletal pain. The ratio of the NSAIDs activity associated with cyclooxygenase (COX) – COX-1 / COX-2 – inhibition allows us to evaluate their potential toxicity. The smaller this value, the more selective the drug is against COX-2, and the less toxic it is. Meloxicam belongs to the predominantly selective COX-2 inhibitors. In the Russian market, meloxicam of domestic production - Amelotex® is widely prescribed. Several studies have shown the high efficacy and safety of meloxicam in the treatment of pain syndromes with different localizations (LBP, neck pain of vertebrogenic nature, OA, etc.), it can be recommended for elderly patients, patients with comorbid diseases such as arterial hypertension (AH), diabetes mellitus, gastrointestinal tract pathology. Meloxicam has a good efficacy and safety profile, a pronounced symptom-modifying effect.

The prevalence and risk factors of chronic low back pain among adults in KwaZulu-Natal, South Africa: an observational cross-sectional hospital-based study

BackgroundGlobally, chronic low back pain (CLBP) is the leading cause of disability associated with economic costs. However, it has received little attention in low-and-middle-income countries. This study estimated the prevalence and risk factors of CLBP among adults presenting at selected hospitals in KwaZulu-Natal.MethodologyThis cross-sectional study was conducted among adults aged ≥18 years who attended the selected hospitals in KwaZulu-Natal during the study period. A self-administered questionnaire was used to collect data on socio-demographic, work-related factors, and information about CLBP. The SPSS version 24.0 (IBM SPSS Inc) was used for data analysis. Descriptive statistics were used for demographic characteristics of participants. CLBP risk factors were assessed using multivariate logistic regression analysis. A p-value of ≤0.05 was deemed statistically significant.ResultsA total of 678 adults participated in this study. The overall prevalence of CLBP was 18.1% (95% CI: 15.3 – 21.3) with females having a higher prevalence than males, 19.8% (95% CI: 16.0 – 24.1) and 15.85% (95% CI: 11.8 – 20.6), respectively. Using multivariate regression analysis, the following risk factors were identified: overweight (aOR: 3.7, 95% CI: 1.1 – 12.3, p = 0.032), no formal education (aOR: 6.1, 95% CI: 2.1 – 18.1, p = 0.001), lack of regular physical exercises (aOR: 2.2, 95% CI: 1.0 – 4.8, p = 0.044), smoking 1 to 10 (aOR: 4.5, 95% CI: 2.0 – 10.2, p < 0.001) and more than 11 cigarettes per day (aOR: 25.3, 95% CI: 10.4 – 61.2, p < 0.001), occasional and frequent consumption of alcohol, aOR: 2.5, 95% CI: 1.1 – 5.9, p < 0.001 and aOR: 11.3, 95% CI: 4.9 – 25.8, p < 0.001, respectively, a sedentary lifestyle (aOR: 31.8, 95% CI: 11.2 – 90.2, p < 0.001), manual work (aOR: 26.2, 95% CI: 10.1 – 68.4, p < 0.001) and a stooped sitting posture (aOR: 6.0, 95% CI: 2.0 – 17.6, p = 0.001).ConclusionThis study concluded that the prevalence of CLBP in KwaZulu-Natal is higher than in other regions, and that it is predicted by a lack of formal education, overweight, lack of regular physical exercises, smoking, alcohol consumption, sedentary lifestyle, manual work, and a stooped posture.

Successful Diagnosis of Sacroiliac Joint Dysfunction.

BackgroundSacroiliac joint (SIJ) pain is one of the most common causes of low back pain, accounting for 15 to 30% of all cases. Although SIJ dysfunction accounts for a large portion of chronic low back pain prevalence, it is often overlooked or under diagnosed and subsequently under treated. The purpose of this review was to establish a best practices model to effectively diagnose SIJ pain through detailed history, physical exam, review of imaging, and diagnostic block.MethodsA literature search was performed on the diagnosis of sacroiliac joint pain and sacroiliac joint dysfunction. The authors proposed diagnostic recommendations based upon the available literature and a detailed understanding of diagnosing SIJ pain.ResultsThe practitioner must focus on the history, location of pain, observed gait pattern, and perform key points of the physical exam including sacroiliac provocative maneuvers. If the patient exhibits at least three provocative maneuvers then the SIJ may be considered as a possible source of pain. Additionally, a thorough review of the imaging should be performed to rule out other etiologies of low back pain. In the absence of any pathognomonic tests or examination findings, diagnostic SIJ blocks have evolved as the diagnostic standard.ConclusionThe diagnosis of SIJ pain is a multifaceted process that involves a careful assessment including differentiating other pain generators in the region. This involves careful history taking, appropriate physical examination including provocative maneuvers and diagnostic injections. Once the diagnosis is confirmed, long-term solutions may be considered, including recent advances in sacral lateral branch denervation and sacroiliac joint fusion.

Associations between the number of children, age at childbirths and prevalence of chronic low back pain: the Nord-Tr\xf8ndelag Health Study

BackgroundAssociations between childbirths and subsequent risk of low back pain (LBP) have not been clarified. Changes in sex hormone levels or lumbar posture during pregnancy may have an impact on LBP later in life. The purpose of this study was to explore associations between the number of childbirths, age at childbirths and prevalence of chronic LBP in a general population of women.MethodsData were obtained from the Norwegian community-based Nord-Trøndelag Health Study, HUNT2 (1995–1997). Women aged 20–69 years indicated whether they suffered from chronic LBP, defined as LBP persisting at least 3 months continuously during last year. Information about LBP was collected from 3936 women who had experienced no childbirths, 3143 women who had delivered one child only and 20,584 women who had delivered 2 or more children. Of these, 7339 women reported chronic LBP. The 595 women who were pregnant when information was collected were considered separately, regardless of previous births, with 80 women reporting chronic LBP. Associations with prevalence of chronic LBP were examined by generalised linear modelling with adjustment for potential confounders in a cross-sectional design.ResultsWomen who had delivered one child only showed a higher prevalence of chronic LBP than women with no childbirths (prevalence ratio (PR) 1.11; 95% CI: 1.01–1.22). Among women with one or more childbirths, no overall change in prevalence could be demonstrated with an increasing number of children in analyses adjusted for age at first delivery. In women with at least two childbirths, an age less than 20 years at first childbirth was associated with an increased prevalence of chronic LBP (PR 1.36; 95% CI: 1.25–1.49; compared with age 25–29 years). No association was observed between age at last delivery and chronic LBP. The lowest prevalence of chronic LBP was found among women who were currently pregnant (PR 0.80; 95% CI: 0.63–1.00; compared with women with no childbirths).ConclusionsHaving experienced at least one childbirth seems to be associated with a higher prevalence of chronic LBP later in life. A young age at first childbirth is also associated with a long-lasting increased prevalence.

Lumbopelvic motor control function between patients with chronic low back pain and healthy controls: a useful distinguishing tool: The STROBE study.

Although lumbopelvic stability exercise improves lumbopelvic motor control function in patients with chronic low back pain (CLBP), the difference in lumbopelvic motor control function between the patients with CLBP and the healthy controls is unclear. The purpose of this study was to compare lumbopelvic motor control function between patients with CLBP and healthy controls and to determine the prevalence of CLBP according to core stability function.For this study, 278 participants were recruited, including patients with CLBP (n = 137) and healthy controls (n = 141). The participants performed a core stability function test and were classified to either the low or high core stability function group according to their core stability function for CLBP prevalence analysis.Lumbopelvic motor control was significantly higher in the healthy controls than in patients with CLBP. Of the patients in the low lumbopelvic motor control function group, 65.9% had CLBP, whereas 36.8% of the patients in the high lumbopelvic motor control function group had CLBP. Lumbopelvic motor control function demonstrated a significant difference between the patients with CLBP and the healthy controls. The lumbopelvic motor control function test was demonstrated to be an effective diagnostic tool for distinguishing CLBP. This information can be applied in assessments and interventions for CLBP in clinical settings.
