A meta-analysis of the association between physical demands of domestic labor and back pain among women

BackgroundBack pain (BP) is among the most common musculoskeletal problems globally and is a leading contributor to disability among adults. Millions of women especially those in low-income settings, engage in strenuous domestic activities that may increase their risk of BP. The purpose of this meta-analysis was to estimate the association between physically demanding domestic labor (PDDL) which is characterized as intensity, frequency, duration of work and biomechanical risk factors of work and BP among women.MethodsFive databases were searched for records published from January 1991 to March 2020; and results from 11studies were included in the meta-analysis. A random effects model and the generic inverse-variance method was used to estimate the pooled odds ratio (OR), 95% confidence interval (CI), and the degree of heterogeneity among studies (I2). Stratified and sensitivity analyses were conducted to identify the influence of outliers and identify the sources of heterogeneity.ResultsExposure to high PDDL was significantly associated with BP (OR = 1.63; 95% CI 1.30, 2.04; I2 = 70%). The odds of back pain were highest among the following groups: women performing domestic labor in non-neutral postures (OR = 2.30; 95% CI = 1.75–3.04; I2 = 0%; N = 4 studies) and among women from low- and middle-income countries (OR = 1.98; 95% CI = 1.58–2.49; I2 = 29%; N = 5 studies). We found no evidence of publication bias (Egger’s test p-value = 0.15).ConclusionsPDDL may significantly increase a woman’s risk of experiencing BP, but larger prospective studies are needed to further investigate the association. Presenting data on how domestic work affects the musculoskeletal health of women will be important in designing future interventions (behavioral, infrastructural, and ergonomic) that can reduce the burdens from domestic labor.

The physician as a success determining factor in CT-guided pain therapy

BackgroundBack pain is a common problem and a burden for the patient. MR-morphologically proven pain-causing changes of the spine is often successfully treated utilizing CT-guided pain therapy. The CT-guided execution enables a controlled and reproducible therapy. Nevertheless, treatment results can differ even with the same patient; the physician is a possible influencing factor of the outcome. Accordingly, the present study analyzes the different behaviors and forms of communication of the treating physicians during the course of the intervention as factors influencing the outcome of treatment.Methods67 patients suffering from specific back pain were included in this study. 5 treating physicians (2 female, 3 male) of different age (29–63 years), and experience and a total of 244 CT-guided treatments were included in this study. In every case a psychologist observed the treatment based on a standardized observation protocol. Observed were both the verbal and non-verbal interactions as well as the reaction of patient and physician. The success of the therapy was measured in the course of the treatment using the visual analogue pain scale. The technical comparability of the performed CT-guided periradicular therapy was ensured by the distribution of the drug mixture.ResultsThe outcome is significantly better if the patient considers the treating physician to be competent (correlation coefficient: 0.24, p < 0.006) and feels understood (correlation coefficient: 0.29, p < 0.001). In addition, the outcome is better when the physician believes that the treatment brings a positive reduction of pain, underlining his belief with positive statements of affirmation before the intervention thus creating a positive atmosphere [correlation coefficient: 0.24 (p < 0.009)]. In contrast, the outcome is worse if the patient complains about pain during the intervention [average pain reduction M = 0.9 (pain group) vs. M = 2.0 (no-pain group)].ConclusionOur study shows that with comparable implementation of CT-guided periradicular therapy, the outcome of the patient with specific back pain can be significantly improved by certain behavioral patterns of the performing physician and this without side effects and without significant additional time expenditure. Our findings indicate that there is a non-negligible psychological factor linking confidence in therapy to actual therapy success.Trial Registration: The study was designed as an observational study, therefore a trial registration was not necessary.

Identifying community physical activity and health resources for treatment of back pain by utilizing members of a physical activity network

BackgroundBack pain is one of the leading causes of health care expenditure in the US and is linked to an increased body mass index. Many evidence-based modalities for the prevention and treatment of back pain closely mirror recommendations for weight loss and include physical activity and health maintenance activities (PAHM). The primary aim of this study was to ascertain community assets, and perceptions of the use of PAHM in the treatment of back pain by West Virginia Physical Activity Network (WVPAN) members.MethodsParticipants for the study were recruited from the West Virginia Physical Activity Network. This grassroots organization is filled with volunteers from various sectors who were recruited from various workshops, conferences, or coalition meetings over a period of several years. This network was purposely selected as the study population because of the statewide reach and their familiarity with resources in their local communities. A brief survey instrument was designed to gather their scaled perceptions about various treatment modalities related to back pain, and to gather their local knowledge related to specific providers in their communities. In addition, participants were given a free text box to list any local assets or resources for the nine treatments listed, and county of residence, and the nature of their connection to the physical activity network. Descriptive analyses were used to describe overall patterns of survey data. The qualitative data were compiled manually by the research team to show themes of specific treatments mentioned across different parts of the state.ResultsParticipants overwhelmingly supported physical therapy, flexibility training, yoga, and core strengthening as treatments for back pain. The majority of respondents were “undecided” about other treatments such as cognitive behavioral therapies and acupuncture.ConclusionsThe implementation of PAHM interventions in communities could help treat patients with back pain, and may reduce reliance on the pharmacological treatment for back pain. The current study’s data support the potential of such approaches in many West Virginia counties. Also, local resources, and context can be gleaned from community leader surveys utilizing previously developed infrastructure for PAHM promotion.

The Back-care Behavior Assessment Questionnaire (BABAQ) for schoolchildren: development and psychometric evaluation

BackgroundBack pain is an important public health problem and the leading cause of adult disability worldwide and is rising among schoolchildren populations. Despite numerous studies reporting on back care interventions in pediatric population; there is currently no existing theory-based instrument to assess impact and outcome of these programs. This paper reports on development and psychometric testing of a theory based back-care behavior instrument for use among elementary schoolchildren.MethodsThis was a three-phases study that included the following steps: a) a literature research to review existing instruments that assess healthy spine-related behavior in elementary schoolchildren; b) development of a new instrument namely the Back-care Behavior Assessment Questionnaire (BABAQ) based on the Social Cognitive Theory and existing instruments, and c) conducting a cross sectional study to test psychometric properties of the BABAQ by estimating the content validity ratio (CVR), the content validity index (CVI), performing confirmatory factor analysis (CFA), reliability analysis, and convergent validity as estimated by the Average Variance Extracted (AVE).ResultsFirst, a questionnaire (the BABAQ) was developed. It contained of 49 items tapping into 5 pre-defined constructs (skills, knowledge, self-efficacy, expectation beliefs, and behavior). Then, 610 fifth-grade female schoolchildren were entered into a cross sectional study and they completed the BABAQ. The CVR and the CVI of the questionnaire was found to be ≥0.54 and > 0.7, respectively. The CFA confirmed the five constructs and showed good fit for the data. The intraclass correlation (ICC) and the Cronbach’s alpha coefficients for the BABAQ were 0.84 (P < 0.001) and 0.93, respectively. The convergent validity as measured by the AVE also showed satisfactory results.ConclusionThe findings suggest that the Back-care Behavior Assessment Questionnaire (BABAQ) is a valid instrument for measuring healthy spine-related behaviors among schoolchildren.

Sick leave due to back pain, common mental disorders and disability pension: Common genetic liability.

Back pain and common mental disorders are often comorbid and known risk factors for future disability pension. However, the reason for the covariation is not known. The aim was to investigate the common genetic and environmental influences on the covariation between sick leave due to back pain, sick leave due to common mental disorders and disability pension. Register data from the Swedish Social Insurance Agency on sick leave due to back pain, common mental disorders and disability pension between 2005 and 2018, in a population-based sample of 56,686 working age twins was used to construct biometric twin models to calculate if the covariation between the traits were due to Additive (A) or Dominant (D) genetic factors, Common environmental factors (C) or unique Environmental factors (E), for women and men. The phenotypic correlations ranged between 0.17 and 0.25. A common factor common pathway AE model fitted best for both women and men. The latent underlying common factor, that explained the covariation was mostly explained by genetic factors (87% for women and 90% for men). Each trait was also influenced by its own unique genetic and unique environment factors. A higher heritability was found for disability pension than for sick leave. The covariation between sick leave due to back pain and common mental disorders, and disability pension were mostly explained by common genetic factors, while the unique variation in each trait was influenced by both genetic and environmental factors not shared within the twin pairs. A common genetic liability seems to be of importance in the comorbidity of sick leave due to back pain and common mental disorders and the transition to disability pension, both among women and men. However, the proportion in each trait that was explained by genetic factors was somewhat higher for men than for women in all traits. This may be of importance to consider in intervention or prevention efforts.

Prevalence of and factors associated with low Back pain, thoracic spine pain and neck pain in Bashkortostan, Russia: the Ural Eye and Medical Study

BackgroundBack pain and neck pain are leading causes of the burden of disease worldwide, while information about their prevalence in Russia is missing.MethodsThe population-based Ural Eye and Medical Study was conducted in a rural and urban region in Bashkortostan/Russia. As part of a detailed systematic examination, we assessed the prevalence of low back pain, thoracic spine pain and neck pain in an interview with standardized questions in 5397 study participants (mean age:58.6 ± 10.6 years;range:40–94 years).ResultsThe mean prevalence of low back pain, thoracic spine pain and neck pain was 2912/5397 (54.0%;95% confidence interval (CI):52.6,55.3), 1271/5397 (23.6%;95%CI:22.4,24.7), and 1570/5397 (29.1%;95%CI:27.9,30.3), respectively. A higher prevalence of low back pain was associated with females (P = 0.04;odds ratio (OR):1.14;95%CI:1.004,1.30), younger age (P < 0.001;OR:0.99;95%CI:0.98,0.99), higher body mass index (P = 0.002;OR:1.02;95%CI:1.01,1.03), lower frequency of vigorous activities during leisure time (P = 0.001;OR:0.79;95%CI:0.69,0.90), more time spent sitting and reclining (P = 0.03;OR:1.00;95%CI:1.00,1.00), higher serum concentration of high-density lipoproteins (P = 0.004;OR:1.10;95%CI:1.03,1.18), higher prothrombin index (P = 0.003;OR:1.01;95%CI:1.003,1.01), higher prevalence of a history of cardiovascular disease (P = 0.004;OR:1.23;95%CI:1.07,1.42), falls (P < 0.004;OR:1.71;95%CI:1.45,2.00), bone fractures (P = 0.01;OR:1.18;95% CI:1.03,1.34), unconsciousness (P < 0.001;OR:1.78;95%CI:1.40,2.25), osteoarthritis (P < 0.001;OR:2.76;95%CI:2.34,3.26), iron-deficiency anemia (P < 0.001;OR:1.87;95%CI:1.41,2.50), and thyroid disorder (P = 0.004;OR:1.37;95%CI:1.10,1.70), fewer days of vegetable intake (P < 0.001;OR:0.89;95%CI:0.85,0.93), smaller amounts of salt intake (P = 0.008;OR:0.97;95%CI:0.94,0.99), higher anxiety score (P < 0.001;OR:1.05;95%CI:1.03,1.06), and in women, history of menopause (P = 0.02;OR:1.36;95%CI:1.05,1.75). The prevalence of thoracic spine pain and neck pain showed similar associations.ConclusionsIn a Russian population, the prevalence of low back pain, thoracic spine pain and neck pain (54.0, 23.6 and 29.1%, respectively) were correlated with parameters such as the female sex, younger age, higher body mass index, higher anxiety score, higher prevalence of a history of cardiovascular disease, lower frequency of vigorous activities and more time spent sitting or reclining. These data may be of interest for assessing the burden of back and neck pain in Russia as part of the global burden of disease.

One-year evaluation of epiduroscopy in chronic back pain with and without radiculopathy: a retrospective study

BackgroundBack pain is a frequent complaint among the individuals in the society. It significantly affects the daily activities and the social and psychological life aspects leading to an economic health burden. Epiduroscopy is a relatively new minimally invasive technique that is used as a diagnostic and therapeutic tool in cases of chronic back pain.Aim of the studyTo evaluate the extent of long-term benefit of epiduroscopy in patients with refractory chronic back pain with/without radiculopathy.Materials and methodsRetrospective data of 148 patients with failed back surgery syndrome (FBSS) and/or symptomatic lumbosacral disc prolapse who underwent epiduroscopy were collected. A 50% reduction in the visual analog scale (VAS) score was set as the primary outcome. Pre- and post-procedure analgesic use, quality of sleep, and changes in the activities of daily livings (ADLs) after 1-year follow-up were reviewed. Incidence and types of complications were recorded.ResultsThe mean age of the studied sample was 56.6 years with a higher percentage of females (61.5%). Patients having radicular pain represented 45.1%. Disc prolapse was prevalent (61.5%) compared to patients with FBSS (38.5%). A reduction of 50% or more in VAS score was reached in 52.7% (p < 0.01). This reduction was more evident in younger patients (p = 0.004). There was an improvement in ADLs (p < 0.01), quality of sleep (p < 0.05), and analgesic intake (p < 0.05).ConclusionEpiduroscopy is a relatively recent, safe, and minimally invasive tool that showed effectiveness in the difficult to treat patients with back pain with/without radiculopathy especially in FBSS.

Association of back pain and pelvic tilt during gait in individuals with cerebral palsy

BackgroundBack pain prevalence may increase with lumbar lordosis during standing in individuals with cerebral palsy (CP). Multiple interventions undertaken in individuals with CP have been shown to increase anterior pelvic tilt. Research questionAre pelvic tilt and trunk tilt (proxy measurements for lumbar lordosis) during gait associated with back pain prevalence in ambulatory individuals with CP? MethodsA retrospective investigation was performed among all patients with cerebral palsy visiting a single clinical motion analysis laboratory over a 3.5 year period (January 2015 – May 2018) who also had complete pain questionnaire data. Back pain prevalence and its association with sagittal plane kinematic parameters (pelvic tilt and trunk tilt) were analyzed. ResultsAmong the 700 patients that met the inclusion criteria, 594 were children and 106 were adults. Back pain prevalence was 11.1% in children and 36.8% in adults. As pelvic tilt and age increased, back pain increased (odds ratio 95% confidence interval: 1.002–1.061 and 1.052–1.109, respectively). Walking with an assistive device was not associated with back pain, nor was trunk tilt. SignificanceBack pain was more common with increasing age in ambulatory individuals with CP. After controlling for assistive device use and age, there was a weak relationship between pelvic tilt and back pain. Future studies are needed to determine if this is this a causal relationship.

Factors associated with chronic and acute back pain in Wales, a cross-sectional study

BackgroundBack pain is one of the most common causes for disability in the working population. Some risk factors for back pain are well known, however little is known about factors uniquely associated with acute or chronic back pain.This study aimed to elucidate patterns uniquely associated with acute or chronic back pain.MethodsThis study performed secondary analysis of data from the Welsh Health Survey 2012, a nationwide cross-sectional survey.A multivariable analysis was carried out for risk factors found to be significantly associated with acute and chronic back pain.ResultsWe found that increased BMI (aOR 1.20, 95% Cis 1.08, 1.33; BMI > 30), mental health score below average (aOR 1.59, 95% CIs 1.47, 1.72), having a degree (aOR 1.28, 95% CIs 1.12, 1.47) and being older than 24 years (P < 0.001) were associated with increased prevalence of acute back pain.Higher prevalence of chronic back pain was seen in individuals characterised by increased deprivation (WIMD) (aOR 1.61, 95% CIs 1.32, 1.96); increased age (aOR 7.34, 95% CIs 5.25, 10.26; for 65+); being female (aOR = 1.43, 95% CIs 1.27, 1.61); lower educational attainment (aOR 0.44, 95% CIs 0.36, 0.55) higher BMI (aOR = 1.60 95% CIs 1.38, 1.85; BMI > 30); poorer mental health score (aOR = 3.11 95% CIs 2.76, 3.51), and a sedentary lifestyle (aOR = 0.58, 95% CIs 0.49, 0.69; 3–5 days of light exercise).ConclusionIncreased deprivation, female gender, and little exercise were uniquely associated with chronic back pain. These characteristics may help clinicians to intervene to prevent acute backpain resulting in chronic cases.

Determining the impact of a new physiotherapist-led primary care model for back pain: protocol for a pilot cluster randomized controlled trial

BackgroundBack pain is a leading contributor to disability, healthcare costs, and lost work. Family physicians are the most common first point of contact in the healthcare system for people with back pain, but physiotherapists (PTs) may be able to support the primary care team through evidence-based primary care. A cluster randomized trial is needed to determine the clinical, health system, and societal impact of a primary care model that integrates physiotherapists at the first visit for people with back pain. Prior to conducting a future fully powered cluster randomized trial, we need to demonstrate feasibility of the methods. Therefore, the purpose of this pilot study will be to:Determine feasibility of patient recruitment, assessment procedures, and retention.Determine the feasibility of training and implementation of a new PT-led primary care model for low back pain (LBP)Explore the perspectives of patients and healthcare providers (HCPs) related to their experiences and attitudes towards the new service delivery model, barriers/facilitators to implementation, perceived satisfaction, perceived value, and impact on clinic processes and patient outcomes.MethodsThis pilot cluster randomized controlled trial will enroll four sites and randomize them to implement a new PT-led primary care model for back pain or a usual physician-led primary care model. All adults booking a primary care visit for back pain will be invited to participate. Feasibility outcomes will include: recruitment and retention rates, completeness of assessment data, PT training participation and confidence after training, and PT treatment fidelity. Secondary outcomes will include the clinical, health system, cost, and process outcomes planned for the future fully powered cluster trial. Results will be analyzed and reported descriptively and qualitatively. To explore perspectives of both HCPs and patients, we will conduct semi-structured qualitative interviews with patients and focus groups with HCPs from participants in the PT-led primary care sites.DiscussionIf this pilot demonstrates feasibility, a fully powered trial will provide evidence that has the potential to transform primary care for back pain. The full trial will inform future service design, whether these models should be more widely implemented, and training agendas.Trial registrationClinicalTrials.gov, NCT03320148.

Back pain in pregnancy among office workers: risk factors and its impact on quality of life.

Background Back pain is a common presenting complaint during pregnancy and it is often being considered as part of the pregnancy process. The purpose of the study is to investigate the prevalence of back pain in pregnancy, risk factors and its impact on the quality of life in pregnant women. Materials and methods Three hundred and fifty-eight pregnant women who attended the antenatal clinic in Universiti Kebangsaan Malaysia (UKM) Medical Centre were recruited in this cross-sectional study from October 2011 until April 2012. The back pain was further classified into lumbar pain and posterior pelvic pain. The severity of back pain was assessed using visual analoque scale (VAS) and the functional limitation was assessed using the Oswestry Disability Questionnaire (ODQ). Result The prevalence of back pain in pregnancy was 84.6%. Occupation and previous history of back pain were associated with back pain in pregnancy. In terms of functional limitation disability, total ODQ score was statistically significant correlate with severity of pain (VAS score). Personal care, sitting, standing, sex life and social life were significantly affected. Conclusion The risk factors for back pain in pregnancy were type of occupation and history of back pain. The higher VAS score, the more ODQ will be affected. Personal care, sitting, standing, sex life and social life were significantly affected.

Rehabilitation access and effectiveness for persons with back pain: the protocol of a cohort study (REHAB-BP, DRKS00011554)

BackgroundBack pain is one of the most common chronic diseases in Germany and has a major impact on work ability and social participation. The German Pension Insurance (GPI) is the main provider of medical rehabilitation to improve work ability and prevent disability pensions in Germany. However, over half of the persons granted a disability pension have never used a medical rehabilitation service. Furthermore, evidence on the effects of medical rehabilitation in Germany is inconclusive. Consequently, this study has two aims: first, to determine barriers to using rehabilitation services, and second, to examine the effectiveness of medical rehabilitation in German residents with chronic back pain.MethodsIn 2017 a postal questionnaire will be sent to 45,000 persons aged 45 to 59 years whose pension insurance contributions are managed by the GPI North or the GPI Central Germany. In 2019 respondents who report back pain in the first survey (n = 5760 expected) will be sent a second questionnaire. Individuals will be eligible for the first survey if they are employed, have neither used nor applied for a rehabilitation programme during the last 4 years and neither received nor applied for a disability pension. The sample will be drawn randomly from the registers of the GPI North (n = 22,500) and the GPI Central Germany (n = 22,500) and stratified by sex and duration of sickness absence benefits. Barriers to rehabilitation services will be related to socio-demographic and social characteristics, pain and attitudes to pain, health and health behaviour, healthcare utilisation, experiences and cognitions about rehabilitation services and job conditions. Propensity score matched analyses will be used to examine the effectiveness of rehabilitation services. Data on use of medical rehabilitation will be extracted from administrative records. The primary outcome is pain disability. Secondary outcomes are pain intensity and days of disability, pain self-efficacy, fear avoidance beliefs, self-rated health, depression, healthcare utilisation, self-rated work ability and subjective prognosis of employability, sickness absence benefits, and disability pensions.DiscussionThis study identifies barriers to use of rehabilitation services and determines the effectiveness of medical rehabilitation for patients with chronic back pain.Trial registrationGerman Clinical Trials Register (DRKS00011554, January 26, 2017).

Mucin 1, a signal transduction membrane-bound mucin, is present in human disc tissue and is downregulated in vitro by exposure to IL-1\xdf or TNF-\u03b1

BackgroundBack pain and disc degeneration have a growing socioeconomic healthcare impact. Mucin 1 (MUC1) is a transmembrane glycoprotein whose extracellular and intracellular domains participate in cellular signaling. Little is currently known about the presence or role of MUC1 in human disc degeneration.MethodsIn this IRB-approved research study, 29 human disc specimens were analyzed for MUC1 immunohistochemical localization and gene expression, and annulus fibrosus (annulus) cells were also isolated and cultured in 3D. Microarray analysis assessed expression levels of MUC1 in healthy and degenerated disc tissue and in cells exposed to proinflammatory cytokines (IL-1ß or TNF-α).ResultsMUC1 was shown to be present in annulus cells at the protein level using immunochemistry, and its expression was significantly upregulated in annulus tissue from more degenerated grade V discs compared to healthier grade I-II discs (p = 0.02). A significant positive correlation was present between the percentage of MUC1-positive cells and disc grade (p = 0.009). MUC1 expression in annulus cells cultured in 3D was also analyzed following exposure to IL-1ß or TNF-α; exposure produced significant MUC1 downregulation (p = 0.0006).ConclusionsHere we present the first data for the constitutive presence of MUC1 in the human disc, and its altered expression during disc degeneration. MUC1 may have an important role in disc aging and degeneration by acting as a regulator in the hypoxic environment, helping disc cells to survive under hypoxic conditions by stabilization and by activation of HIF-1α as previously recognized in pancreatic cancer cells.

Is there an association between back pain and stress incontinence in adults with cystic fibrosis? A retrospective cross-sectional study

BackgroundBack pain and stress urinary incontinence (SUI) are common in adults with cystic fibrosis (CF). This study aimed to establish whether there is an association between back pain, lung function and stress urinary incontinence and its relative risk. MethodThis was a cross-sectional, retrospective analysis of the Manchester Musculoskeletal Screening Tool (MMST) data. It includes pain, (Short Form McGill Pain Questionnaire (SF-MPQ and VAS)) and International Consultation on Incontinence Short Form (ICIQ-UI-SF) measures. Associations were tested using Spearman's rank correlation coefficient. Relative risk of developing symptoms was calculated the sig level was p=0.05. ResultsICIQ-UI-SF was associated with back pain (SF-MPQ) (Rho=0.32, p<0.001) and pain (VAS) (Rho=0.23, p<0.01). RR of developing SUI with back pain was 2; RR of developing back pain with SUI was 1.3. ConclusionsAn association is indicated between back pain (SF-MPQ and VAS), and SUI in adults with CF. This information is important when developing management strategies in the CF population.

Mapping the association between back pain and type 2 diabetes: A cross-sectional and longitudinal study of adult Spanish twins.

BackgroundBack pain and type 2 diabetes often co-occur, resulting in greater impact on people’s health and complexity in their care. Plausible causal mechanisms for this association have been proposed, yet the nature of the link remains unclear. We therefore explored the direction of the association between type 2 diabetes and chronic back pain in twins, controlling for genetics and early environmental confounding.Methods2,096 and 1,098 twins were included in the cross-sectional and longitudinal analyses, respectively. Any or severe (≥ 9) low back pain (LBP), neck pain (NP), and spinal pain (concurrent LBP and NP) and type 2 diabetes were investigated. Sequential analyses were performed using logistic regression. Firstly, twins were analysed unpaired (adjusted age and gender): total sample analyses. Then, to control for genetic and shared environmental factors, a co-twin case-control analysis was performed including monozygotic and dizygotic twin pairs discordant for back pain (cross-sectional only).ResultsIn the cross-sectional total sample analyses, type 2 diabetes was associated with chronic spinal pain (OR 1.61; 95%CI 1.12 to 2.31), severe chronic spinal pain (OR 3.33; 95%CI 1.47 to 7.53), chronic NP (OR 1.37; 95%CI 1.01 to 1.85), severe chronic NP (OR 2.28; 95%CI 1.24 to 4.21), and severe chronic LBP (OR 1.63; 95%CI 1.00 to 2.64). After further adjustment for genetic and shared environmental factors, none of the associations remained significant. The longitudinal analyses indicated that the presence of type 2 diabetes did not increase the risk of future back pain, or vice-versa, after two to four years.ConclusionsChronic back pain (spinal pain, NP, or LBP) was associated with the prevalence of type 2 diabetes. Associations are stronger for severe cases of pain. Future research should investigate the temporal relationships between these conditions with longer follow up in twins.

Severity of back pain may influence choice and order of practitioner consultations across conventional, allied and complementary health care: a cross-sectional study of 1851 mid-age Australian women.

BackgroundBack pain is a common, disabling and costly disorder for which patients often consult with a wide range of health practitioners. Unfortunately, no research to date has directly examined the association between the severity of back pain and back pain sufferers’ choice of whom and in what order to consult different health practitioners.MethodsThis is a sub-study of the large nationally representative Australian Longitudinal Study on Women’s Health (ALSWH). The mid-age cohort women (born 1946-51, n = 13,715) of the ALSWH were recruited from the Australian national Medicare database in 1996. These women have been surveyed six time, with survey 6 being conducted in 2010 (n = 10,011). Mid-age women (n = 1851) who in 2010 had sought help from a health care practitioner for their back pain were mailed a self-report questionnaire targeting their previous 12 months of health services utilisation, health status and their levels of back pain intensity.ResultsA total of 1620 women were deemed eligible and 1310 (80.9 %) returned completed questionnaires. Mid-age women with back pain visited various conventional, allied health and CAM practitioners for care: 75.6 % consulted a CAM practitioner; 58.4 % consulted a medical doctor; and 54.2 % consulted an allied health practitioner. Women with the most severe back pain sought conventional care from a general practitioner, and those who consulted a general practitioner first had more severe back pain than those who consulted another practitioner first. Following the general practitioner visit, the women with more severe back pain were more likely to be referred to a conventional specialist, and those with less severe back pain were more likely to be referred to a physiotherapist.ConclusionsOur findings suggest that women with more severe back pain are likely to visit a conventional practitioner first, whereas women with less severe back pain are likely to explore a range of treatment options including CAM practitioners. The improvement of back pain over time following the various possible sequencing of consultations with different types of health practitioners is a topic with implications for ensuring safe and effective back pain care and worthy of further detailed investigation.

Tweeting back: predicting new cases of back pain with mass social media data.

Back pain is a global health problem. Recent research has shown that risk factors that are proximal to the onset of back pain might be important targets for preventive interventions. Rapid communication through social media might be useful for delivering timely interventions that target proximal risk factors. Identifying individuals who are likely to discuss back pain on Twitter could provide useful information to guide online interventions. We used a case-crossover study design for a sample of 742 028 tweets about back pain to quantify the risks associated with a new tweet about back pain. The odds of tweeting about back pain just after tweeting about selected physical, psychological, and general health factors were 1.83 (95% confidence interval [CI], 1.80-1.85), 1.85 (95% CI: 1.83-1.88), and 1.29 (95% CI, 1.27-1.30), respectively. These findings give directions for future research that could use social media for innovative public health interventions.

Is back pain during childhood or adolescence associated with muscle strength, muscle endurance or aerobic capacity: three systematic literature reviews with one meta-analysis.

BackgroundBack pain is a common condition during childhood and adolescence. The causes of back pain are largely unknown but it seems plausible that some physical factors such as back muscle strength, back muscle endurance and aerobic capacity may play a role in its development, in particular in the early years.ObjectivesThe objectives of this review were to investigate in childhood and adolescence 1) if muscular strength in trunk extension is associated with back pain, 2) if muscular endurance in trunk extension is associated with back pain and 3) if aerobic capacity is associated with back pain.DesignThree systematic critical literature reviews with one meta-analysis.MethodsSystematic searches were made in June 2014 in PubMed, Embase and SportDiscus including longitudinal, retrospective or cross-sectional studies on back pain for subjects <20 years. Articles were accepted if they were written in French or English. The review process followed the AMSTAR recommendations. The possibility of conducting a meta-analysis was assessed for each research question.ResultsFour articles were included for the first objective, four for the second and three for the last. None of the included articles found an association between back muscle strength in extension and back pain. For the second objective, a protective association between back muscle endurance in extension and back pain was found, later confirmed in a meta-analysis (OR = 0.75, 95 % CI 0.58-0.98). The association between aerobic capacity and back pain is not clear.ConclusionsHigh back muscle endurance in extension appears protective of back pain in youngsters, but the roles of high back muscle strength in extension and aerobic capacity are less clear.
