Prevalence of low back pain in different educational levels: a systematic review

Is educational attainment associated with the onset and outcomes of low back pain? a systematic review and meta-analysis

BACKGROUND

Low back pain (LBP) is the leading global cause of years lived with disability. Of the biopsychosocial domains of health, social determinants of LBP remain under-researched. Socioeconomic status (SES) may be associated with the onset of new LBP or outcomes of acute LBP, with educational attainment (EA) being a key component of SES. The association between EA and LBP has yet to be the subject of a dedicated review and meta-analysis.

PURPOSE

To review evidence of the association between EA and a) onset or b) outcomes of acute and subacute LBP in the adult general population and to conduct statistical pooling of data where possible.

METHODS

An electronic search was conducted in MEDLINE, Embase, CINAHL, and ProQuest from inception to 2nd November 2023 including reference lists to identify relevant prospective studies. Risk of bias (RoB) was assessed using the Quality in Prognostic Studies (QUIPS) tool. Where adequate data were available, estimates were pooled using a random-effects meta-analysis. Overall evidence for each outcome was graded using an adapted GRADE.

RESULTS

After screening 8498 studies, 29 were included in the review. Study confounding and attrition were common biases. Data from 19 studies were statistically pooled to explore EA as a predictor of new LBP onset or as prognostic for outcomes of acute or subacute LBP. Pooled results showed no association between EA and the onset of new LBP (OR: 0.927, 95%CI: 0.747 to 1.150; I2 = 0%). For predicting outcomes of acute LBP, compared to those with no more than secondary-level education, post-secondary education or higher was associated with better outcomes of pain (OR: 0.538, 95%CI: 0.432 to 0.671; I2 = 35%) or disability (OR: 0.565, 95%CI: 0.420 to 0.759; I2 = 44%). High heterogeneity (I2>80%) prevented meaningful pooling of estimates for subacute LBP outcomes.

CONCLUSION

We found no consistent evidence that lower EA increases the risk of LBP onset. Lower EA shows a consistent association with worse LBP outcomes measured at least 3 months later after acute onset with inconclusive findings in subacute LBP. Causation cannot be supported owing to study designs. High-quality research is needed on potential mechanisms to explain these effects.

The mediating role of depressive symptoms among Turkish population related to gender and low back pain: evidence from a national health survey

BACKGROUND

Low back pain (LBP), though non-life-threatening, burdens healthcare with treatment expenses and work hours lost. Globally, 70-84% experience it, with risk factors tied to societal structure, income, and living conditions, making it a leading cause of disability.

METHODS

This study utilized data from the 2019 Türkiye Health Survey, which consisted of 17,084 individuals aged 15 and above. Our study focused on investigating the factors related to low back pain through a cross-sectional analysis. To analyze these factors, we employed binary multivariate logistic regression. Additionally, we conducted post-hoc analyses to assess the potential mediating effect of depressive symptoms on the relationship between low back pain and gender.

RESULTS

We found that 31.9% of the population experienced low back pain, with women being 58% more likely [aOR = 1.58; 95% CI (1.45-1.73)] than men to report symptoms. Individuals aged 55 + years old had a 90% [aOR = 1.90; 95% CI (1.61-2.23)] chance of experiencing low back pain, indicating an age-related increase. In the general population, having depressive symptoms was 2.49 [95% CI (2.23-2.78)] times more likely associated with low back pain. Our mediation analysis showed that gender (i.e., women vs. men), indicated by direct effects with β-estimates e = 0.78, predicted the likelihood of low back pain. Additionally, the relationship between gender and low back pain, mediated through a history of depressive symptoms, had a significant total indirect effect (i.e., β-estimate given as e = 0.49). Specifically, a history of depressive symptoms accounted for 17.86% [95% CI (9.67-20.10)] of the association between women having a higher likelihood of low back pain compared to men.

CONCLUSION

We observed that a higher likelihood of low back pain associated with gender and aging. Additionally, BMI served as a significant predictor, particularly in adults. Depression mediated the association between gender and low back pain. Acknowledging these associations may help identify and address contributing factors to LBP, potentially increasing awareness and alleviating the burden. Policymakers and healthcare professionals may consider these findings when developing prevention and treatment programs for low back pain.

Pain and associated factors in German occupational therapists: a nationwide cross-sectional survey study

Background

Back pain is a common event in the general German population, but little is known about pain prevalence among occupational therapists (OT).

Objective

The aim of this study was to estimate the prevalence of pain and associated factors in German OTs.

Methods

We conducted a cross-sectional survey study. The prevalence of acute, chronic, and recurrent pain was calculated, and factors associated with chronic and recurrent pain were identified using multivariate logistic regression analysis.

Results

A total of 444 OTs (89.41% female) with a mean age of 37.78 (SD = 11.63) years were included into the final analysis. Prevalence of acute pain was 3.83% (95% confidence interval [95% CI]: 2.25%; 6.06%), of chronic pain 15.54% (95% CI: 12.30%; 19.25%), and of recurrent pain 43.02% (95% CI: 38.36%; 47.77%). The most frequently affected pain site was the lumbar spine. Significantly associated with chronic pain was the level of depression (adjusted odds ratio [AOR]: 1.05 [95% CI 1.00; 1.10]; p ≤ 0.042) of study participants. Recurrent pain was significantly associated with a standing working position, working in geriatrics, stress level, and the level of graduation in multivariate analysis.

Conclusion

This study estimated the prevalence of pain and identified factors associated with chronic and recurrent pain in participating OTs. To provide prevention measures and to identify more factors, further studies should be conducted.

Sociodemographic and Clinical Characteristics Associated With Worst Pain Intensity Among Cancer Patients

AIMS

Patients with cancer have pain due to their cancer, the cancer treatment and other causes, and the pain intensity varies considerably between individuals. Additional research is needed to understand the factors associated with worst pain intensity. Our study aim was to determine the association between worst pain intensity and sociodemographics and cancerspecific factors among patients with cancer.

DESIGN

A total of 1,280 patients with cancer recruited from multiple cancer centers over 25 years in the United States were asked to complete a questionnaire that collected respondents' demographic, chronic pain, and cancer-specific information.

SETTINGS

Worst, least, and current pain intensities were captured using a modified McGill Pain Questionnaire (pain intensity measured on 0-10 scale). A generalized linear regression analysis was utilized to assess the associations between significant bivariate predictors and worst pain intensity scores.Our study sample was non-Hispanic White (64.5%), non-Hispanic Black (28.3%), and Hispanic (7.2%). On average, participants were 59.4 (standard deviation = 14.4) years old. The average worst pain intensity score was 6.6 (standard deviation = 2.50). After controlling for selected covariates, being Hispanic (β = 0.6859), previous toothache pain (β = 0.0960), headache pain (β = 0.0549), and stomachache pain (β = 0.0577) were positively associated with worse cancer pain. Notably, year of enrollment was not statistically associated with pain.

CONCLUSIONS

Our study sample was non-Hispanic White (64.5%), non-Hispanic Black (28.3%), and Hispanic (7.2%). On average, participants were 59.4 (standard deviation = 14.4) years old. The average worst pain intensity score was 6.6 (standard deviation = 2.50). After controlling for selected covariates, being Hispanic (β = 0.6859), previous toothache pain (β = 0.0960), headache pain (β = 0.0549), and stomachache pain (β = 0.0577) were positively associated with worse cancer pain. Notably, year of enrollment was not statistically associated with pain. Findings identified being Hispanic and having previous severe toothache, stomachache, and headache pain as significant predictors of worst pain intensity among patients with cancer. After controlling for selected covariates, we did not note statistical differences in worst pain during a 25-year period. Therefore,studies focused on improving the management of pain among patients with cancer should target interventions for those with Hispanic heritage and those with past history of severe common pain.

Caring-Related Chronic Low Back Pain and Associated Factors among Mothers of Children with Cerebral Palsy

BACKGROUND

Literature indicated some risk factors for low back pain; however, there is insufficient knowledge on the effect of caring-related physical activities and individual characteristics on Chronic Low Back Pain (CLBP) in mothers of children with Cerebral Palsy (CP).

OBJECTIVE

The main aim of the current study was to determine the association between caring-related physical activities, Body Mass Index (BMI), education level, and CLBP in mothers of children with CP.

DESIGN

Case-control observational study. Setting. Pediatric rehabilitation clinics. Participants. Mothers of children with CP. Main Outcome Measures. Measures is comprised of a self-administered questionnaire that included the demographic characteristics items, pain visual analog scale, and three items of the job-related physical demands questionnaire. The logistic regression model served to assess the association.

RESULTS

The control group included 81 healthy mothers, with a mean (SD) age of 39 (8.45) years, and the case group contained 90 mothers who suffered from CLBP, with a mean (SD) age of 37 (8.64) years. Performing lifting movements (OR 13.73, β = 2.62, p < .001), BMI (OR 11.85, β = 2.47, p = .011), repetitive bending (OR 7.67, β = 2.04, p = .010), forward-flexion (OR 6.71, β = 1.91, p = .033), and level of education (OR .21, β = -1.53, p = .020), in descending order of odds ratios, were found to be significant predictors of the CLBP in mothers of children with CP.

CONCLUSION

Avoiding caring-related harmful physical activities, maintaining body weight within a healthy range, and increasing knowledge for accurate lifting/handling techniques can be helpful to prevent the CLBP in mothers of children with CP.

[Influence of Social Status on the Success of Rehabilitation among Patients with Chronic Low Back Pain - Results of a 2-year Follow-up after Inpatient Multidisciplinary Rehabilitation]

PURPOSE

Social inequality in medical rehabilitation is receiving increasing attention. The present study examined the impact of the social status on the long-term effectiveness of the pain competence and depression prevention training "Debora" among patients with chronic low back pain (CLBP) in an inpatient multidisciplinary rehabilitation.

METHODS

The control group study with cluster-block randomization investigated the long-term changes in pain self-efficacy, psychological burden, functional capacity, and subjective work ability among 394 patients with non-specific CLBP depending on the condition (control group, CG: pain competence training vs. intervention group, IG: additional depression prevention training) and the social status (lower, middle vs. upper class; according to Deck [1]). The data were collected at five sample points: pre (t₀), post (t₁), 6-(t₂), 12-(t₃) and 24-month follow-up (t₄). Multi- or univariate repeated-measures analyses of variance were conducted per protocol (pp). In a second step, results should be confirmed by multiple imputations (MI; N=1089).

RESULTS

In general, patients of the lower class showed significantly worse values in depressive symptoms, functional capacity, and subjective work ability compared to the upper class. In addition, positive long-term effects could not be found among patients of the lower class. In contrast, patients of the middle and upper class improved, especially in the IG. Furthermore, only the IG showed long-term improvements in subjective work capacity.

CONCLUSION

This study confirms the influence of the social status on the psychophysical health. Moreover, social inequality in long-term success of rehabilitation of CLBP was suggested, which could be mediated by health literacy. Therefore, these aspects should be taken into account already in the conception and especially in the application of psychological group trainings in inpatient rehabilitation.

The Economic and Social Burden of Low Back Pain in Spain: A National Assessment of the Economic and Social Impact of Low Back Pain in Spain

STUDY DESIGN

Economic evaluation of the costs of low back pain (LBP) in Spain from a societal perspective, including direct and indirect costs, based on a national representative sample of the general population, the National Health Survey of 2017 (NHS 2017).

OBJECTIVE

To estimate the costs attributable to LBP in Spain.

SUMMARY OF BACKGROUND DATA

LBP has a high prevalence and is associated with lower quality of life, functional status, and increased use of health services. Studies that assess the socio-economic burden of LBP from a general population perspective have not been published yet in Spain.

METHODS

Data from NHS 2017 were used. Direct costs (consultations-general practitioner, specialist and emergency departments-, diagnostic tests, hospitalizations, physiotherapy, psychologist, and medication consumption) and indirect costs (absenteeism and presenteeism) were assessed. Multivariate models were obtained to determine the independent attributable effect of LBP in each variable. Costs were determined through existing regional healthcare services public data.

RESULTS

Prevalence of LBP was 17.1% for men and 24.5% for women, and increased with age, low educational status, higher body mass index, and was associated with less physical activity, and lower self-perceived health. Multivariate analysis demonstrated that LBP was independently associated with a significant increase both in the utilization of all health services and on work day losses. Attributable costs of LBP were 8945.6 million euros, of which 74.5% implied indirect costs, representing overall 0.68% of Spanish Gross Domestic Product.

CONCLUSION

Spain is paying a heavy price for LBP, mostly associated with its significant impact on absenteeism and presenteeism, as well as a noteworthy effect on excess health services utilization. These findings underscore the need to address this considerable public health and social problem through interventions that address widely LBP and that have demonstrated to be cost-effective.

Challenges in postural orientations for workers away from work with low back pain

Abstract Introduction: Postural orientations are necessary in cases of low back pain, and challenges arise in chronic cases. Objective: To investigate the challenges in the postural orientation of workers in a situation of absence from work and with chronic low back pain. Methods: The study was divided into two steps. In the first stage, physiotherapists that were taking part in the “Low Back Pain Project” at the Reference Center for Worker’s Health in Santos-SP were invited, and a script was used to conduct individual interviews that were recorded for thematic content analysis. In the second stage, there was a selection of workers that were patients attended by the Physical Therapy sector, with chronic low back pain and in a situation of absence from work, and a Discussion Group was conducted with the patients and physical therapists, which was also recorded for content analysis. Results: In stage 1, three physiotherapists aged 26 to 33 years old participated. The statements revealed: intense work demands, little understanding of the patients’ difficulties, “stigmas” related to the situation of absence from work, among others. In stage 2, fourteen workers participated, aged between 47 and 50, of both sexes and different professions along with the three physiotherapists. The group evidenced: difficulties in daily living activities outside the therapeutic environment, disrespect to physical restrictions at work, fear of returning to work, among others. Conclusion: Challenges related to work organization aspects and psychosocial issues were found, and it is necessary to advance in the teaching-learning processes.
