Assessment of the prevalence and associated factors of lower back pain (LBP) among three different professionals in Bangladesh: Findings from a face-to-face survey.

OBJECTIVES: This study aims to evaluate the prevalence and associated factors of lower back pain (LBP) among farmers, rickshaw pullers and office workers in Bangladesh, while also investigating potential contributors within these occupational groups. DESIGN: This cross-sectional study aimed to determine the prevalence of LBP, associated factors and management procedures among farmers, rickshaw pullers and office workers in Bangladesh through face-to-face interviews. SETTING: The study was conducted in different parts of the Bogura district in Bangladesh. PARTICIPANTS: A total of 396 participants were included in the final analysis, all the participants were men and adult in age. MAIN OUTCOME MEASUREMENTS: Data were collected using a semi-structured questionnaire based on previous research. Bivariate and multivariable logistic regression analyses were performed to identify significant associations. RESULTS: The prevalence of LBP was found to be 42.7% among the participants. Farmers and rickshaw pullers had approximately four-times and three-times higher odds of experiencing LBP compared with office workers. Other significant factors associated with LBP included living in a nuclear family, having a normal body weight, lacking professional training, having a chronic disease, having a family history of LBP and experiencing numbness in the legs or feet. The majority of respondents sought medical attention and took medication for their LBP. CONCLUSION: The study underscores occupational differences in LBP prevalence, emphasising the necessity for tailored interventions and occupational health policies. Identifying specific risk factors and management practices in these professions can aid in developing effective prevention strategies and enhancing healthcare services.

Serum 25-Hydroxyvitamin D Status and Vitamin D Supplements Use Are Not Associated with Low Back Pain in the Large UK Biobank Cohort.

Longitudinal studies assessing the association of vitamin D deficiency, defined by serum 25-hydroxyvitamin D levels < 30 nmol/L, and vitamin D supplement (VDS) use with low back pain (LBP) are sparse. This investigation assessed the cross-sectional and longitudinal association of vitamin D status and VDS use with LBP among 135,934 participants from the UK Biobank cohort. Approximately 21.6% of the participants had vitamin D deficiency, while only 4% regularly took VDS. In the month before study enrollment, 3.8% of the population reported experiencing LBP. An additional 3.3% of the population were diagnosed with LBP by their general practitioners for the first time during a median follow-up of 8.5 years. Vitamin D deficiency and VDS use were cross-sectionally associated with LBP in age- and sex-adjusted models, but these associations were not evident in comprehensively adjusted models. In longitudinal analyses, both vitamin D deficiency and VDS use were not associated with LBP in any model after correction for multiple testing. In conclusion, not unexpectedly due to the fact that LBP is multifactorial, our findings provide no evidence for the role of the vitamin D status in the etiology of LBP.

An investigation into the frequency and risk factors of low back pain following surgical treatment of isolated calcaneal fractures.

OBJECTIVE: This study aimed to determine the frequency of low back pain after calcaneal fractures treated with open reduction internal fixation (ORIF) and the risk factors that cause this condition. METHODS: Thirty-one patients (27 males and 4 females) who underwent surgery for a unilateral calcaneal fracture between 2016 and 2020 and had no complaints of low back pain before fracture surgery were included in the study. The patients were divided into 2 groups: those who developed low back pain after the operation and those who did not. Patients were evaluated with the Life Quality Short Form SF-36, the Oswestry Disability Index (ODI), and American Orthopedic Foot-Ankle Association Score (AOFAS). Sanders' fracture type, joint range of motion (ROM) measurements of injured and uninjured limbs, maximal isometric muscle strength measurements, balance on 1 leg with pedobarographic measurements, and walking time were evaluated. The obtained data were compared among the 2 groups. RESULTS: Low back pain was observed in 71% of the patients and was detected after an average of 6 months from the operation. In ODI, 59.1% of the patients reported that low back pain limited their lives slightly. Patients with low back pain have lower AOFAS scores and worse SF-36 physical functionality than those without low back pain (P < .001, P=.016). Balance time on 1 foot in pedobarographic measurements, foot in ROM, ankle in ankle active, passive plantar flexion, inversion, active hip, passive internal, external rotation, muscle is the foot eversion force. In these measurements, the values of the injured side are intact. It was statistically significantly lower than the other side (interaction P < .1). CONCLUSION: Low back pain may occur after unilateral calcaneal fractures treated by ORIF. This may be caused by decreased angles of ankle dorsi and plantar flexion, foot inversion, hip abduction, and internal and external rotation. In the rehabilitation program, not only the ankle region but also the hip joint of the affected side should be included, and the kinetic chain that describes the interaction mechanism of the human body should not be forgotten. LEVEL OF EVIDENCE: Level IV, Prognostic Study.

Association of depressive symptoms with risk of incidence low back pain in middle-aged and older Chinese adults.

BACKGROUND: Elevated Depressive symptoms (DS) and low back pain (LBP) pose significant and growing public health challenges, and China is no exception. This study innovatively examined the relationship between specific DS and distinct patterns of DS and incident LBP. METHODS: This study extracted data from 4713 participants aged 45+ years from the China and Health Retirement Longitudinal Study (CHARLS), followed-up for incidence LBP (June 2011-September 2020). DS was assessed by the 10-item Center for Epidemiological Studies Depression Scale (CESD-10). The incident LBP was determined by self-reported. Latent class analysis (LCA) was employed to categorize patterns of DS. Cox proportional hazards regression models were used to examine the association between DS and incident LBP. RESULTS: Over the 9.25-year follow-up period, 2234 incident LBP cases were identified. There was a significant independent association between positive DS and incident LBP with an HR of 1.73 (95 % CI = 1.55-1.94). Of the 10-item DS, difficulty concentrating (adjusted HR = 1.16, 95 % CI = 1.03-1.31), effortfulness (adjusted HR = 1.32, 95 % CI = 1.18-1.49), hopelessness (adjusted HR = 1.13, 95 % CI = 1.02-1.25), restless sleep (adjusted HR = 1.17, 95 % CI = 1.06-1.30), and loneliness (adjusted HR = 1.18, 95 % CI = 1.02-1.36), each independently associated with incident LBP. Regarding patterns of DS, compared to the "healthy" pattern of DS, four patterns showed significant association with incident LBP, especially the cumulative pattern of DS. LIMITATIONS: DS and LBP were assessed based on self-reported. CONCLUSIONS: In middle-aged and older Chinese adults, 5 specific DS (difficulty concentrating, effortfulness, hopelessness, restless sleep, and loneliness) and distinct patterns of DS indicate varied risks of developing LBP.

Global, Regional, and National Change Patterns in the Incidence of Low Back Pain From 1990 to 2019 and Its Predicted Level in the Next Decade.

Objectives: To analyze and describe the spatiotemporal trends of Low back pain (LBP) burdens from 1990 to 2019 and anticipate the following decade's incidence. Methods: Using data from the Global Burden of Disease (GBD) 2019 Study, we described net drifts, local drifts, age effects, and period cohort effects in incidence and forecasted incidence rates and cases by sex from 2020 to 2029 using the Nordpred R package. Results: LBP remained the leading cause of the musculoskeletal disease burden globally and across all socio-demographic index (SDI) regions. China is the top country. For recent periods, high-SDI countries faced unfavorable or worsening risks. The relative risk of incidence showed improving trends over time and in successively younger birth cohorts amongst low-middle-, middle- and high-middle-SDI countries. Additionally, the age-standardized incidence rates (ASIR) of LBP in both sexes globally showed a decreasing trend, but the incident cases would increase from 223 to 253 million overall in the next decade. Conclusion: As the population ages, incident cases will rise but ASIR will fall. To minimise LBP, public awareness and disease prevention and control are needed.

Association between chiropractic spinal manipulation and cauda equina syndrome in adults with low back pain: Retrospective cohort study of US academic health centers.

BACKGROUND: Cauda equina syndrome (CES) is a lumbosacral surgical emergency that has been associated with chiropractic spinal manipulation (CSM) in case reports. However, identifying if there is a potential causal effect is complicated by the heightened incidence of CES among those with low back pain (LBP). The study hypothesis was that there would be no increase in the risk of CES in adults with LBP following CSM compared to a propensity-matched cohort following physical therapy (PT) evaluation without spinal manipulation over a three-month follow-up period. METHODS: A query of a United States network (TriNetX, Inc.) was conducted, searching health records of more than 107 million patients attending academic health centers, yielding data ranging from 20 years prior to the search date (July 30, 2023). Patients aged 18 or older with LBP were included, excluding those with pre-existing CES, incontinence, or serious pathology that may cause CES. Patients were divided into two cohorts: (1) LBP patients receiving CSM or (2) LBP patients receiving PT evaluation without spinal manipulation. Propensity score matching controlled for confounding variables associated with CES. RESULTS: 67,220 patients per cohort (mean age 51 years) remained after propensity matching. CES incidence was 0.07% (95% confidence intervals [CI]: 0.05-0.09%) in the CSM cohort compared to 0.11% (95% CI: 0.09-0.14%) in the PT evaluation cohort, yielding a risk ratio and 95% CI of 0.60 (0.42-0.86; p = .0052). Both cohorts showed a higher rate of CES during the first two weeks of follow-up. CONCLUSIONS: These findings suggest that CSM is not a risk factor for CES. Considering prior epidemiologic evidence, patients with LBP may have an elevated risk of CES independent of treatment. These findings warrant further corroboration. In the meantime, clinicians should be vigilant to identify LBP patients with CES and promptly refer them for surgical evaluation.

Evaluation of three decades of the burden of low back pain in China before COVID-19: Estimates from the Global Burden of Disease Database 2019.

Background: Low back pain (LBP) is reported as an urgent public-health concern globally because it occurs in all age groups and is now the leading cause of disability, with health systems unable to cope with this burden. We present China's burden of LBP by estimating its prevalence and years lived with disability (YLDs) from 1990 to 2019. Methods: We obtained the data relating to LBP from the Global Burden of Disease Database (GBD) 2019. Then we calculated years lived with disability caused by LBP by multiplying the prevalence of LBP sequelae by their corresponding disability weights. We performed an analysis of the age-, sex-, and province-specific prevalence and YLDs of 33 provinces/regions in China, as well as their relationship with the sociodemographic index (SDI). Results: China has the largest numbers of people with LBP (91.3 million) and YLDs (8.6 million) globally, and LBP is the leading cause of YLDs. The age-standardised prevalence was 7.25% in 1990, and this decreased to 5.13% in 2019. The age-standardised YLD rate was 579/100 000 in 2019, having decreased by 28.97%. Both measurements increased with age, being higher in women and varying across the 33 provinces/regions. For the 5-to-14-year age group, the prevalence (4.50%) and YLD rate (4.51%) increased in 2019 from 1990 (3.21% and 3.21%, respectively) when compared to the elderly group. Age-standardised YLD rates experienced decreases with increasing SDI, while there was an increasing tendency as SDI increased further; the changes for women were more obvious. Conclusions: Over the three decades considered, China has continued to have the largest number of people with LBP in the world, even though the age-standardised prevalence has decreased. YLDs were found to decrease as SDI increased, but they subsequently increased again. LBP still presents a burden, particularly for children and postmenopausal women.

The key determinants of low back pain among lifestyle behaviors in adolescents: A cross-sectional study from Saudi Arabia.

Establishing preventive measures and treatment strategies for adolescents with low back pain (LBP) may be greatly enhanced by fully grasping the complex interaction between LBP and lifestyle behaviors. The key objective of this study was to explore the possible associations between lifestyle behaviors and LBP among adolescents in Saudi Arabia. A cross-sectional study was conducted among high school students from 5 major regions in Saudi Arabia. Participants were enlisted for the research project between May and November 2021. To evaluate the presence/severity of LBP, physical activity, sedentary duration, sleep quality, nutrition, health responsibility, interpersonal relationships, spiritual growth, and stress management, a well-established web-based survey was employed. A total of 2000 students participated, with 57.9% reporting LBP. Students with LBP had lower scores on overall health-promoting lifestyle behaviors and all subscales, including physical activity, compared to those without LBP. Linear regression analysis revealed significant associations between sedentary duration and global sleep quality with pain severity among students with LBP. This study highlights the association between lifestyle behaviors and LBP among adolescents in Saudi Arabia. Promoting physical activity, reducing sedentary behavior, and improving sleep quality may be crucial in preventing and managing LBP in this population. Comprehensive strategies targeting lifestyle behaviors should be implemented to improve the well-being of adolescents and reduce the burden of LBP. Further research is needed to better understand the underlying mechanisms and develop effective preventive and treatment strategies for LBP among adolescents.

Smoking and BMI mediate the causal effect of education on lower back pain: observational and Mendelian randomization analyses.

Objective: Low back pain (LBP) has been associated with education in previous observational studies, but the causality remains unclear. This study aims to assess the impact of education on LBP and to explore mediation by multiple lifestyle factors. Design: Univariable Mendelian randomization (MR) was performed to examine the overall effect of education on LBP. Subsequently, multivariable MR was conducted to assess both the direct effect of education on LBP and the influence of potential mediators. Indirect effects were estimated using either the coefficient product method or the difference method, and the proportion of mediation was calculated by dividing the indirect effect by the total effect. The observational study utilized data from the NHANES database collected between 1999 and 2004, and included 15,580 participants aged 20 years and above. Results: Increasing education by 4.2 years leads to a 48% reduction in the risk of LBP (OR=0.52; 95% CI: 0.46 to 0.59). Compared to individuals with less than a high school education, those with education beyond high school have a 28% lower risk of LBP (OR=0.72; 95% CI: 0.63 to 0.83). In the MR study, smoking accounts for 12.8% (95% CI: 1.04% to 20.8%) of the total effect, while BMI accounts for 5.9% (95% CI: 2.99% to 8.55%). The combined mediation effect of smoking and BMI is 27.6% (95% CI: 23.99% to 32.7%). In the NHANES study, only smoking exhibits a mediating effect, accounting for 34.3% (95% CI: 21.07% to 41.65%) of the effect, while BMI does not demonstrate a mediating role. Conclusions: Higher levels of education provide a protective effect against the risk of LBP. Additionally, implementing interventions to reduce smoking and promote weight loss among individuals with lower levels of education can also decrease this risk.

Low back pain, pelvic pain, and associated factors in type 1 diabetic pregnant women.

INTRODUCTION: Pregnancy and diabetes mellitus promote several musculoskeletal changes predisposing this population to complaints of Lower Back (LB) and Pelvic Pain (PP). OBJECTIVE: To assess the frequency of LB and PP and associated factors in type 1 Diabetic (DM1) pregnant women. METHOD: An observational analytical cross-sectional study. Thirty-six pregnant women with DM1 were evaluated through a postural assessment with a focus on pelvic positioning and what patients reported. The associated factors were assessed using the State-Trait Anxiety Inventory (STAI), the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and the Female Sexual Function Index (FSFI). RESULTS: The frequency of LB and PP was 55.6 % and 30.6 %, respectively. The presence of anxiety was not associated with a higher prevalence of pain. The incidence of sexual dysfunctions was higher in the GD. DM1 duration had a mean of 14.9 years (± 8.2 SD) in the GD and 9.0 years (± 6.9 SD) in the GSD, which was statistically significant (p ≤ 0.050). In the multiple binary regression analysis for the occurrence of pain, the independent factor was DM1 duration ≥ 17 years (OR = 11.2; 95 % CI = 1.02‒124.75). The association between DM1 duration ≥ 17 years and being overweight showed a probability of 95 % for the studied population in the analysis of the probabilities of occurrence of the pain event. CONCLUSION: There was a high frequency of LB and PP related to pregnancy in DM1 pregnant women in the second trimester of pregnancy. The incidence of sexual dysfunction and DM1 duration ≥ 17 years increases the chance that DM1 pregnant women will experience pain. There was no association between anxiety. urinary incontinence and pain in DM1 pregnant women.

Subgroup characteristics in care workers with low back pain: cluster analysis-based severity of central sensitivity syndromes and low back pain.

PURPOSE: This multicentre, collaborative, cross-sectional study aimed to explore the characteristics of subgroups based on central sensitivity syndromes (CSSs) and low back pain (LBP) severity. Furthermore, we investigated the relationship between the classified subgroups and work status among the care workers. PATIENTS AND METHODS: In 660 care workers, we assessed LBP intensity, pain duration, pain sites, CSS (using the central sensitization inventory-9), psychological factors (using the pain catastrophizing scale and pain self-efficacy questionnaire), and work status (interference, amount of assistance, frequency of assistance, and work environment). We used hierarchical clustering analysis to divide the participants into subgroups based on CSS and LBP severity. We further performed multiple comparison analyzes and adjusted the residuals (chi-square test) to reveal differences between clusters. RESULTS: Care workers with LBP were divided into four subgroups (Cluster 1: no CSS and mild LBP, Cluster 2: mild CSS and severe LBP, Cluster 3: mild CSS and mild LBP, Cluster 4: severe CSS and moderate LBP). Cluster 4 tended to have a higher number of pain sites, severe pain catastrophizing, and poor pain self-efficacy. In addition, Cluster 4 showed a higher frequency of assistance and an inadequate working environment and equipment. By contrast, Cluster 2 tended to have low pain self-efficacy. In addition, Cluster 2 experienced the highest work-related interference compared with any of the subgroups. CONCLUSION: Our findings suggested that the severe LBP and severe CSS subgroups had common and different characteristics concerning psychological factors and work status, including interference with work. Our results may help to improve the management of care workers with LBP.

Reconsidering high intensity zones: its role in intervertebral disk degeneration and low back pain.

PURPOSE: High intensity zones (HIZ) in the lumbar intervertebral disk (IVD) can be associated with degenerative changes which may ultimately manifest as low back pain (LBP). However, the relationship between the prevalence of HIZ and lumbar degenerative parameters is still unclear. The purpose of this study was to determine the prevalence of HIZ in the lumbar spine, analyze the independent relationship between HIZ and lumbar degenerative parameters measured on MRI and X-ray and determine the association between HIZ and the presence of LBP. METHODS: A retrospective review of MRI data, X-ray data, and radiology reports for 136 consecutively recruited patients, above 18-years-age and with both lumbar MRI and X-ray scans was conducted. 57 patients with HIZ were identified. Patients without HIZ (n = 79) made up the control group. RESULTS: HIZ was prevalent in 41.9% of patients and in 11.0% of all lumbar IVDs. The odds of developing HIZ were 6.4 (Exp(B) 6.4, 95%CI [3.157-12.988]) and 3.0 (Exp(B) 3.0, 95%CI [1.603, 5.674]) times higher in IVDs with disk bulge/protrusion and nucleus degeneration, respectively. Odds of HIZ was also increased in disks with larger IVD angle (Exp(B) 1.1, 95%CI [1.034, 1.169]). The odds of patients presenting to imaging with LBP was 3.0 (OR 3.0, 95%CI [1.478-6.338]) times higher in the HIZ compared to the control group. CONCLUSIONS: HIZ was prevalent in 41.9% of participants that were recruited in this study. Nucleus degeneration, disk bulge/protrusion and increased IVD angle were found to be independently associated with HIZ and since there is an increased likelihood of LBP, we posit that HIZ is likely a symptomatic and clinically meaningful diagnostic tool in the assessment of LBP.

The Incidence of Pelvic and Low Back Pain in Patients with Pelvic Organ Prolapse.

INTRODUCTION AND HYPOTHESIS: To define the prevalence and incidence of pelvic/low back pain in patients with pelvic organ prolapse (POP). METHODS: Patients presenting for POP to three urogynecology centers in the US, UK, and Chile were enrolled in an IRB-approved cross-sectional study assessing pain, GU, GI and sexual function symptoms. For prevalence, symptoms were noted as present if the participant recorded the symptom and reported the degree of bother as "somewhat," "a moderate amount," or "a lot." For incidence, participants were queried if the symptom's onset concurred with the POP. We also queried if they perceived the symptom was worsened by their POP. RESULTS: Two hundred five participants were recruited: 100 from the US, 46 from the UK, and 59 from Chile. One US participant was excluded due a missing examination. The prevalence of pelvic pain was 42%. Seventy-three percent of these participants reported the onset of pelvic pain coinciding with prolapse onset, and 81% endorsed worsening pelvic pain with POP. The prevalence of low back pain was 46%, with 30% reporting the onset coincided with the onset of POP and 44% responded that prolapse worsened their pain. CONCLUSION: A higher proportion of participants than expected endorsed pelvic/low back pain. Among patients with pelvic pain, the majority experienced symptom onset with POP onset and a worsening of pain with POP. While roughly half of participants reported low back pain; a minority correlated this to their POP. These findings highlight a high incidence of pelvic pain, challenging the perception of POP as a painless condition.

Identifying latent subgroups in the older population seeking primary health care for a new episode of back pain - findings from the BACE-N cohort.

BACKGROUND: Back pain is the number one condition contributing to years lived with disability worldwide, and one of the most common reasons for seeking primary care. Research on this condition in the ageing population is sparse. Further, the heterogeneity of patients with back pain complicates the management in clinical care. It is possible that subgrouping people with similar characteristics would improve management. This paper aimed to identify latent classes based on demographics, pain characteristics, psychosocial behavior, and beliefs and attitudes about back pain, among older patients seeking primary care with a new episode of back pain, and to examine if there were differences regarding the classes' first point-of-contact. METHODS: The study was part of the international BACE (Back complaints in elders) consortium and included 435 patients aged ≥ 55 years seeking primary care (general practitioners, physiotherapists, and chiropractors) in Norway from April 2015 to March 2020. A latent class analysis was performed to identify latent classes. The classes were described in terms of baseline characteristics and first point-of-contact in primary care. RESULTS: Four latent classes were identified. The mean age was similar across groups, as were high expectations towards improvement. Class 1 (n = 169, 39%), the "positive" class, had more positive attitudes and beliefs, less pain catastrophizing and shorter duration of current pain episode. Class 2 (n = 31, 7%), the "fearful" class, exhibited the most fear avoidance behavior, and had higher mean pain intensity. Class 3 (n = 33, 8%), the "distressed" class, had the highest scores on depression, disability, and catastrophizing. Finally, class 4 (n = 202, 46%), the "hopeful" class, showed the highest expectations for recovery, although having high pain intensity. The identified four classes showed high internal homogeneity, sufficient between-group heterogeneity and were considered clinically meaningful. The distribution of first point-of-contact was similar across classes, except for the positive class where significantly more patients visited chiropractors compared to general practitioners and physiotherapists. CONCLUSIONS: The identified classes may contribute to targeting clinical management of these patients. Longitudinal research on these latent classes is needed to explore whether the latent classes have prognostic value. Validation studies are needed to evaluate external validity.

Post-Operative Complications Associated with Long-Term NSAID or Long-Term Opioid Use Prior to Lumbar Spinal Fusion Surgery.

OBJECTIVE: Lower back pain (LBP) has been implicated as a significant cause of chronic pain in the United States, often requiring analgesic use. In this study, we investigate the trends in long-term preoperative NSAID (LTN) and Opioid (LTO) use in patients with low back pain in the United States, and the resultant postoperative complications following lumbar fusion. METHODS: In this retrospective cohort study of patients with lumbar pathologies, multivariate population-based regression models were developed using the 2010-2017 National Readmission Database. Short-term complications (30-, 90-day) and long-term complications (180-, 300-day) were analyzed at readmission. RESULTS: Of patients diagnosed with LBP (N = 1427,190) we found a rise in LTO users and a fall in LTN users following 2015. We identified 654,264 individuals who received a lumbar spine fusion, of which 22,975 were LTN users and 11,213 were LTO users. LTO users had significantly higher total inpatient charges (p-value<0.0001) and LOS (p-value<0.0001), while LTN users had lower rates of acute infection (OR: 0.993, 95% CI: 0.987-0.999, p = 0.017) and acute posthemorrhagic anemia (OR: 0.957, 95% CI: 0.935-0.979, p < 0.001) at primary admission. Readmission analysis showed that LTN use had significantly lower odds of readmission compared to LTO use at all time points (p < 0.01 for all). LTN use had significantly higher odds of hardware failure (OR: 1.134, 95% CI: 1.039-1.237, p = 0.005) within 300-days of receiving a lumbar fusion. CONCLUSIONS: LTO users had significantly higher readmission rates compared to LTN. In addition, we found that LTN use was associated with significantly higher odds of hardware failure at long-term follow-up in patients receiving lumbar fusion surgery.

Acceptability, values, and preferences of older people for chronic low back pain management; a qualitative evidence synthesis.

BACKGROUND: Chronic primary low back pain (CPLBP) and other musculoskeletal conditions represent a sizable attribution to the global burden of disability, with rates greatest in older age. There are multiple and varied interventions for CPLBP, delivered by a wide range of health and care workers. However, it is not known if these are acceptable to or align with the values and preferences of care recipients. The objective of this synthesis was to understand the key factors influencing the acceptability of, and values and preferences for, interventions/care for CPLBP from the perspective of people over 60 and their caregivers. METHODS: We searched MEDLINE, CINAHL and OpenAlex, for eligible studies from inception until April 2022. We included studies that used qualitative methods for data collection and analysis; explored the perceptions and experiences of older people and their caregivers about interventions to treat CPLBP; from any setting globally. We conducted a best fit framework synthesis using a framework developed specifically for this review. We assessed our certainty in the findings using GRADE-CERQual. RESULTS: All 22 included studies represented older people's experiences and had representation across a range of geographies and economic contexts. No studies were identified on caregivers. Older people living with CPLBP express values and preferences for their care that relate to therapeutic encounters and the importance of therapeutic alliance, irrespective of the type of treatment, choice of intervention, and intervention delivery modalities. Older people with CPLBP value therapeutic encounters that validate, legitimise, and respect their pain experience, consider their context holistically, prioritise their needs and preferences, adopt a person-centred and tailored approach to care, and are supported by interprofessional communication. Older people valued care that provided benefit to them, included interventions beyond analgesic medicines alone and was financially and geographically accessible. CONCLUSIONS: These findings provide critical context to the implementation of clinical guidelines into practice, particularly related to how care providers interact with older people and how components of care are delivered, their location and their cost. Further research is needed focusing on low- and middle-income settings, vulnerable populations, and caregivers.

Prevalence of low back pain and disability among secondary school teacher in the eastern province of the Kingdom of Saudi Arabia: a cross-sectional analytical study.

Introduction: Lower back pain is common worldwide and affects over 600,000 people annually, including teachers. The study aimed to investigate the prevalence of low back pain and disability among secondary school teachers in the Eastern Province of the Kingdom of Saudi Arabia. Materials and methods: This cross-sectional study included secondary school teachers in the eastern province of Saudi Arabia. 34 schools were selected using a multistage stratified sampling approach. Teachers were allotted randomly and proportionally to each school. Data was collected by anonymous questionnaire having three elements: sociodemographic and health-related questions, the Standardized Nordic Questionnaire, and the Oswestry Low Back Pain Disability Questionnaire. The anthropometric data was also included. Both unadjusted and adjusted logistic regression analyses were performed. Results: A total of 601 teachers participated in the study with 62.56% reported low back pain. The overall mean age was 40.31 ± 8.13 years. The male-to-female ratio was similar. Back pain was significantly higher among females than males (73.36 and 51.52%, respectively). Additionally, back pain will significantly increase when stress levels and the number of classes increases. A positive correlation was found between age with low back pain (p = 0.001).There was minimal disability in 64.63% of the 376 teachers who reported low back pain, moderate disability in 29.79%, and severe disability in 4.79%, and only three (0.8%) were considered crippled. Females were more frequently seen in moderate and crippled categories, and perceived stress levels generally increased mean disability scores. Age and female gender were revealed to be significant predictors of low back pain by logistic regression (adjusted odds ratio [OR] = 1.04, 95% confidence interval [CI] = 1.02-1.07) and (adjusted OR = 2.11, 95% CI = 1.45-3.05), respectively. The number of classes per week was also a significant predictor. Conclusion: This study adds to the epidemiological evidence that reveals a high prevalence of low back pain and disability among teachers. Identified risk factors in this study may also reinforce the importance of setting different interventions and preventive measures to reduce lower back pain risk.

Causal associations between gut microbiota with intervertebral disk degeneration, low back pain, and sciatica: a Mendelian randomization study.

PURPOSE: Although studies have suggested that gut microbiota may be associated with intervertebral disk disease, their causal relationship is unclear. This study aimed to investigate the causal relationship between the gut microbiota and its metabolic pathways with the risk of intervertebral disk degeneration (IVDD), low back pain (LBP), and sciatica. METHODS: Genetic variation data for 211 gut microbiota taxa at the phylum to genus level were obtained from the MiBioGen consortium. Genetic variation data for 105 taxa at the species level and 205 metabolic pathways were obtained from the Dutch Microbiome Project. Genetic variation data for disease outcomes were obtained from the FinnGen consortium. The causal relationships between the gut microbiota and its metabolic pathways and the risk of IVDD, LBP, and sciatica were evaluated via Mendelian randomization (MR). The robustness of the results was assessed through sensitivity analysis. RESULTS: Inverse variance weighting identified 46 taxa and 33 metabolic pathways that were causally related to IVDD, LBP, and sciatica. After correction by weighted median and MR-PRESSO, 15 taxa and nine pathways remained stable. After FDR correction, only the effect of the genus_Eubacterium coprostanoligenes group on IVDD remained stable. Sensitivity analyses showed no evidence of horizontal pleiotropy, heterogeneity, or reverse causation. CONCLUSION: Some microbial taxa and their metabolic pathways are causally related to IVDD, LBP, and sciatica and may serve as potential intervention targets. This study provides new insights into the mechanisms of gut microbiota-mediated development of intervertebral disk disease.

Association between different composite dietary antioxidant indexes and low back pain in American women adults: a cross-sectional study from NHANES.

BACKGROUND: Low back pain is the leading cause of productivity loss, imposes a significant economic burden on the patients and society. Oxidative stress is considered a critical factor in the complex pathophysiological process and pathogenic mechanism of low back pain. Adjustment dietary pattern can effectively increase antioxidant biomarkers levels within the body to reduce oxidative stress. The composite dietary antioxidant index (CDAI) serves a reliable scoring system for quantifying the potential dietary antioxidant capacity of daily diets. OBJECTIVE: We aim to investigate the potential association between CDAI and low back pain, in order to enhance the management of low back pain through dietary guidance. METHODS: This study included 17,682 participants from the National Health and Nutrition Examination Survey (NHANES) 1999-2000, 2001-2002, 2003-2004 and 2009-2010. The weighted logistic regression model was used to investigate the association between CDAI and low back pain, while restricted cubic spline (RCS) was employed to examine non-linear trend and cutoffs. RESULTS: After adjusting for all confounders, the results showed that there was no significant association between CDAI and low back pain. However, individuals in the highest quartile of CDAI exhibited an 11.7% less likelihood of experiencing a low back pain than those in the lowest quartile (OR = 0.883; 95% CI [0.787,0.991], P = 0.034), and the trend test was also significant (P for trend < 0.001). RCS indicated a linear relationship between CDAI and low back pain (P for non-linear = 0.876). Gender subgroup analysis showed that this negative association was significant in the female population (OR = 0.983; 95% CI [0.968, 0.998], P = 0.027), and females in the highest quartile of CDAI were 19.7% less likely to suffer low back pain than those in the lowest quartile (OR = 0.803; 95% CI [0.682,0.945], P = 0.008). Additionally, the changes in zinc (OR = 1.009; 95% CI [1.002, 1.016], P = 0.015) and selenium (OR = 0.379; 95% CI [0.164, 0.875], P = 0.023) per milligram were independently associated with low back pain. CONCLUSION: The fully adjusted model showed no significant association between CDAI and low back pain, but it was significant in quartiles. Meanwhile, subgroup analysis by gender revealed a negative association between CDAI and low back pain in the female population. Additionally, the findings of this study also suggested that the antioxidant diets should be studied in a dietary pattern context.
