Lower Back Pain as an Occupational Hazard Among Ugandan Health Workers

Low back pain among the working-age population: from the global burden of disease study 2021

BACKGROUND

The burden of low back pain in the global working-age population (WAP) is substantial and exhibits unique characteristics. This study aimed to evaluate global, regional, and national trends in low back pain prevalence among the WAP over a 32-year period.

METHODS

We utilized data from the 2021 Global Burden of Disease (GBD) study to evaluate the global impact of low back pain in the WAP from 1990 to 2021. A secondary analysis focused on temporal trends and a decomposition analysis of low back pain.

RESULTS

From 1990 to 2021, there was a continuous decrease in the rate of low back pain among the global WAP. The age-standardized incidence rate (ASIR) decreased from 4,111 (95% uncertainty interval [UI]: 2,682-5,619) to 3,676 (95% UI: 2,563-5,021), with an annual average percentage change (AAPC) of -0.36. The age-standardized prevalence rate (ASPR) decreased from 9,731 (95% UI: 7,061-12,970) to 8,632 (95% UI: 6,296-11,517), with an AAPC of -0.39. The age-standardized disability-adjusted life years (DALYs) rate (ASDR) decreased from 1,108 (95% UI: 686-1,650) to 982 (95% UI: 608-1,460), with an AAPC of -0.39. However, the number of low back pain cases in the global WAP continued to increase. Regions with a middle Socio-demographic Index (SDI), South Asia, China, and India carried a heavier burden of low back pain in the WAP. The burden was also greater among females, with the gender gap continuing to widen. Decomposition analysis revealed that population growth and population aging were the predominant driving factors.

CONCLUSIONS

Despite the overall reduction in the ASIR, ASPR, and ASDR of low back pain among WAP, it remained a leading cause of disability worldwide. More attention needs to be paid to the low back pain burden among WAP in middle-SDI regions, countries with a large population base, and females. Significant gender and regional disparities persist within WAP, highlighting the necessity for targeted preventive and therapeutic interventions to alleviate the burden of low back pain and reduce the risks of disability.

Prevalence, predisposing factors, and turnover intention related to low back pain among health workers in Accra, Ghana

BACKGROUND

Globally, low back pain (LBP) is responsible for disability among 60.1 million people. Health workers face a higher likelihood of being exposed to LBP compared to employees in the construction and manufacturing sectors. Data on LBP among hospital workers in Ghana are however limited. This study examined the prevalence, predisposing factors and turnover intention related to LBP among health workers in the Greater Accra region of Ghana.

METHODS

A multi-centred facility-based cross-sectional study was conducted in the Greater Accra region from January 30 -May 31, 2023. A multi-stage sampling technique was adopted, and the study participants were selected through proportion-to-size simple random sampling. STATA 15 software was used for analysis. Logistic regression analysis was used to determine the factors associated with LBP at a p < 0.05.

RESULTS

A survey was conducted among 607 health workers in 10 public and private hospitals. The prevalence of LBP was 81.6% [95% CI: (78.2%-84.6%)]. Advanced age [AOR = 1.07 (1.00, 1.16)], working for more than 5 days in a week [AOR = 8.14 (2.65, 25.02)], working overtime [AOR = 2.00 (1.16, 3.46)], rarely involved in transferring patients [AOR = 3.22 (1.08, 9.60)], most of the time involved in transferring patients [AOR = 6.95 (2.07, 23.26)], awkward posture during work [(AOR = 2.36 (1.31, 4.25)], perceived understaffing [(AOR = 1.84 (95% CI = 1.04-3.27)], sleep duration ≥ 8 [AOR = 0.54 (0.31, 0.97)] and sitting intermittently at work [AOR = 0.31 (0.12, 0.80)] were factors significantly associated with LBP. A substantial number, 123 (24.9%), occasionally had intention of leaving their jobs.

CONCLUSION

The study revealed a high proportion of low back pain (LBP), and turnover intention attributed to LBP. Moreover, organizational and occupational factors were found to be significantly associated with LBP. These findings underscore the importance of targeted interventions aimed at reducing the burden of LBP within these specific areas.

Lower back pain amongst medical trainees in clinical rotations: implications for choosing future career regarding medical practice

Background

Low back pain (LBP) is an increasing concern amongst medical students. There is a dearth of publications regarding how the occurrence of LBP impact medical trainees' career decisions.

Objective

To determine: (i) the point and annual prevalence of LBP amongst Ugandan medical students, (ii) its associated factors, and (iii) whether the experience of LBP during clinical rotations influence medical students' career choices regarding medical practice.

Methods

A multi-center cross-sectional study of 387 randomly selected clinical-phase students was conducted in three Ugandan medical schools, during 17th January to 10th March 2023. Proportions of participants with current and 12-months history of LBP were computed as well as odds for career prospects. We performed binary logistic regression models to determine factors associated with LBP at 95% confidence interval regarding p < 0.05 as statistically significant.

Results

The response rate was 100%. Participants' mean age was 24.7 ± 3.2 years of which 66.2% (256/387) were males. The point and annual prevalence of LBP was 52.5% (203/387) and 66.1% (256/387) respectively. Age [OR 1.23, 95% CI (1.03-1.47), p = 0.02], time spent sitting per day [OR 1.08, 95% CI (1.06-1.3), p < 0.01], perceived influence of LBP on future medical career [OR 4.75, 95% CI (1.87-12.06), p < 0.01] were the significant predictors of LBP. LBP interrupted the students' learning for at least 6.8 ± 12.8 h in 42.4% of participants. Nearly half of participants affirmed that their LBP experience would influence their career prospects. Based on their LBP experiences, trainees ruled out surgery 51.5% (172/334), obstetrics/gynecology 29.6% (99/334), paediatrics 18.3% (61/334), and internal medicine 17.7% (59/334) as their future career specialties. The proportion of trainees that would not consider surgical as opposed to medical disciplines were 81.1% vs. 36.0%, respectively, (p < 0.001).

Conclusion

The high prevalence of low back pain among medical students impacts their choices of future medical career with an aversion towards specialization in surgical disciplines. This has far-reaching implications on the disparities in specialist physician health workforce in Low-middle-income countries.

HIF-1α protects nucleus pulposus cells from oxidative stress-induced mitochondrial impairment through PDK-1

The pathogenesis of intervertebral disc degeneration (IVDD) involves complex signaling networks and various effector molecules, and our understanding of the pathogenesis of IVDD is limited. Hypoxia inducible factor-1α (HIF-1α) is closely related to IVDD, and there is excessive oxidative stress concurrent with IVDD. In this study, we found that HIF-1α could protect nucleus pulposus cells from excessive oxidative stress by reversing the imbalance between oxidants and antioxidants and thus mitigating the oxidative stress-induced mitochondrial impairment. With further exploration, we found that pyruvate dehydrogenase kinase 1 (PDK-1) was involved in the protective effect of HIF-1α on nucleus pulposus cells under oxidative stress. We suggested that HIF-1α could preserve the mitochondrial integrity and activate glycolysis in nucleus pulposus cells via PDK-1, and the addition of DCA, a PDK-1 inhibitor, could blunt the protective effect of HIF-1α. In addition, the HIF-1α/PDK-1 regulatory axis was also confirmed in vivo through HIF-1α knockout mice model. Therefore, we propose that HIF-1α protects nucleus pulposus cells from excessive oxidative stress by maintaining the mitochondrial integrity and glycolysis via PDK-1, thus enriching the insight into the protective mechanism of HIF-1α against IVDD, and providing a novel therapeutic target for the treatment of IVDD.

The prevalence of occupational-related low back pain among working populations in sub-saharan Africa: a systematic review and meta-analysis

INTRODUCTION

Work-related musculoskeletal disorders represent a major public health problem, contributing significantly to the global burden of disability-adjusted life years and affecting the quality of life of all population groups. The main problem in most musculoskeletal disorders is low back pain. Therefore, our study aims to identify the overall prevalence of work-related low back pain among the working population in sub-Saharan Africa.

METHODS

Research published between 2010 and 2023 in English, conducted in Sub-Saharan Africa was included in this systematic review and meta-analysis. Using Boolean logic operators and targeted keywords, we searched for publications on a number of electronic databases (Web of Science, PubMed, Google Scholar, African Journals Online (AJOL), and Science Direct). The Joanna Briggs Institute Critical Appraisal techniques were utilized to conduct a quality assessment of the papers and ascertain their relevance to the study. The degree of heterogeneity among the included studies, the 95% confidence interval, and the pooled prevalence were estimated using a random effects model. Sensitivity studies were carried out to determine the causes of heterogeneity and the impact of outliers.

RESULTS

In this study, a total of 970 articles were retrieved, and 35 studies were included in the systematic review and meta-analysis. The overall estimated pooled prevalence of low back pain among the working population in sub-Saharan Africa was (55.05% [95% CI: 49.34, 60.76]). Based on a sub-group analysis by countries, the higher pooled prevalence of low back pain was found in Uganda at (61.48% [95% CI: 40.39, 82.57]), while the lower pooled prevalence of low back pain was in Ghana at (34.48% [95% CI: 17.96, 51.01]).

CONCLUSIONS

This systematic review and meta-analysis found that 55.05% of the included study participants experienced low back pain in the previous years. Therefore, it is recommended that policymakers incorporate and enhance strategies for the prevention and management of low back pain within the health system management guidelines of each country.

Low back pain in medical workers and its influencing factors

PURPOSE

To investigate the prevalence of occupational lower back pain (OLBP) among medical workers and identify the contributing factors.

METHODS

An electronic questionnaire was distributed to medical workers at Yuebei People's Hospital to gather information on various factors, including gender, age, body mass index (BMI), length of employment, job role, education level, professional title, marital status, fertility status, frequency of night shift, weight lifting daily, duration of daily standing at work, frequency of bending, work-related stress, experience with low back protection training, and frequency of waist exercises. Univariate and multivariate logistic regression analyses were conducted to identify the factors associated with OLBP in medical workers.

RESULTS

Out of the 98 medical workers surveyed, 67 experienced OLBP (68.37%). The results of multivariate logistic regression analysis revealed that working for more than 5 years, holding a nursing position, and lacking training in low back protection were significant risk factors for developing OLBP in medical workers (all P<0.05).

CONCLUSION

OLBP is a prevalent issue among medical workers, and various factors such as length of employment, job role, and training in low back protection can influence its occurrence.

Low back pain prevention behaviors and beliefs among the Polish population in a cross-sectional survey

Background

Low back pain (LBP) is one of the most common problems of public health and creates a burden globally. The aim was to assess the Polish population's back pain prevention behaviors and beliefs and to examine how these health behaviors and beliefs vary across sociodemographic factors and physical activity.

Methods

A cross-sectional survey was carried out among 208 randomly selected patients of the public general practitioner clinic. The differences in LBP-related beliefs and attitudes were determined due to participants' status of requiring or non-requiring LBP treatment.

Results

More than half of the respondents did not engage in behaviors that protect against back pain. Individuals with higher education levels and those who exercised at least once a week were significantly more likely to adopt behaviors to protect their backs. Less than half of the participants reported having a workplace that was adequately prepared to protect against back pain, and only 35.1% of the participants reported receiving instruction while taking up work on how to avoid back pain while working. According to respondents' opinions, preventive actions are necessary to protect against back pain. Inappropriate exercises and stress can be contributors to back pain, with these opinions reported more often by women and participants with higher education levels. Participants who received treatment for LBP showed a significantly higher expression of behaviors to protect against back pain compared to participants who did not require treatment. However, there were no significant differences in participants' beliefs about back pain prevention between the group requiring LBP treatment and the group not requiring LBP treatment.

Conclusion

The study provides valuable insights into the association between LBP treatment, back pain prevention behaviors, and beliefs, suggesting potential avenues for future research and intervention development. By addressing workplace ergonomics and promoting a culture of back health, it may be possible to reduce the burden of LBP in Poland.

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.

Regulating inflammation and apoptosis: A smart microgel gene delivery system for repairing degenerative nucleus pulposus

The progression of intervertebral disc degeneration (IDD) is attributed to the gradual exacerbation of cellular apoptosis and impaired extracellular matrix (ECM) synthesis, both of which are induced by progressive inflammation. Therefore, it is crucial to address the inflammatory microenvironment and rectify the excessive apoptosis of nucleus pulposus cells (NPCs) to achieve intervertebral disc (IVD) regeneration. In this study, we devised a smart microgel gene delivery system that incorporates functionalized gene nanoparticles (NPs) for the purpose of IVD regeneration. siGrem1 was loaded into the NPs to enhance their antiapoptotic ability and protective effects. Furthermore, the encapsulation of HADA further endows the NPs (referred to as HSGN) with targeted delivery and anti-inflammatory effects, as well as reactive oxygen species (ROS) scavenging capacities. To create an microenvironment-responsive microgel system, phenylboronic acid-functionalized microspheres (referred to as M.S.) were fabricated and dynamically loaded with the HSGN. This microgel system (MHSGN), which is highly biocompatible, enables the sustained release of siGrem1, effectively modulating inflammation, scavenging ROS, and alleviating apoptosis in NPCs. These multifunctional capabilities promote the restoration of metabolic homeostasis within the nucleus pulposus ECM, ultimately leading to delayed IDD.

Review of the Current Situation of Postoperative Pain and Causes of Inadequate Pain Management in Africa

Postoperative pain is one of the most prevalent complications following surgery, and more than 47% of surgical patients endure postoperative discomfort worldwide. In Africa, due to resource shortages and other issues, postoperative pain is substantially more common when compared to developed countries. Severe postoperative pain has many negative effects, including possibly death, which can burden both individuals and society as a whole. Therefore, effectively controlling postoperative pain is becoming increasingly important. To enhance the effectiveness of future pain management, a thorough analysis of the current reasons for inadequate postoperative pain management is necessary. In this article, the present situations of occurring postoperative pain, children's postoperative pain, and pain management in Africa are reviewed, based on relevant and recent literature. In particular, the reasons for inadequate postoperative pain management in Africa are detailed in this article from five perspectives: the inadequate assessment of postoperative pain, the knowledge gap among medical professionals, the patients' misconceptions, the scarcity of resources, and the lack of medications. Additionally, we offer appropriate solutions following various factors.

Musculoskeletal Pain in the Neck and Lower Back Regions among PHC Workers: Association between Workload, Mental Disorders, and Strategies to Manage Pain

Scientific evidence indicates that workers in the health sector are commonly exposed to work-related musculoskeletal pain.

OBJECTIVES

We aimed to identify the relationship between the presence and intensity of musculoskeletal pain in the neck and lumbar regions reported by Primary Health Care (PHC) workers with workloads and occupational risks, analyze musculoskeletal pain in the presence and absence of self-reported mental disorders based on a medical diagnosis, and identify workers' strategies to manage pain.

METHOD

This cross-sectional study addressed 338 health professionals working in PHC outpatient services in the extreme South of Brazil. One questionnaire addressed sociodemographic questions concerning occupation, occupational risks, and mental disorders. The Nordic Musculoskeletal Questionnaire was used to assess self-reported musculoskeletal pain. The National Aeronautics and Space Administration Task Load Index (NASA-TLX) measured the workload. A descriptive and inferential analysis was performed using SPSS version 21.0.

RESULTS

Most (55.3%) participants reported neck and (64.5%) lower back pain in the previous 12 months, and 22.5% and 30.5% reported intense neck and lower back pain, respectively, in the previous 12 months. The results showed different independent associations with increased musculoskeletal pain among health workers. Dentists presented the highest prevalence of neck pain, while female workers presented the highest prevalence of lower back pain. Furthermore, the perception of ergonomic risk and virtually all self-reported mental disorders (except panic syndrome for neck pain) were associated with pain in the neck and lower back regions and a higher frustration level (mental demand). Additionally, professionals with graduate degrees, nurses, and professionals working the longest in PHC services reported seeking complementary therapies more frequently, while physicians and those with self-reported mental disorders self-medicated more frequently.
