Gender differences in the prevalence of low back pain associated with sports activities in children and adolescents: a six-year annual survey of a birth cohort in Niigata City, Japan

Frequency of back pain occurrence among high school youth including their physical activity

BACKGROUND

Back pain diseases are among frequently reported health problems. Unfortunately, more often this problem also affects young people, high school students. Lifestyle that people are representing nowadays has a negative impact on their spine. Development of technology and transportation eliminates daily basic physical activity such as taking a walk to the school. Prolonged and inappropriate sitting posture during classes and using the computer at home are predisposing factors for back pain occurrence. The aim of this paper was to analyze the frequency of back pain occurrence among high school youth and attempt to relate their occurrence frequency with sex, time spent in sitting position, anthropometric parameters and physical activity of examined students.

METHODS

The examined group initially counted 272 teenagers, but ultimately 218 were taken into account for the analysis and 54 questionnaires were filled in incorrectly and rejected. All of them were high school students. Customized survey consisting of general part and closed questions regarding physical activity (subjective experience of work load) was used as an examination tool.

RESULTS

Examined youth spent on average 10.04 hours daily in a sitting position. As much as 195 (89.45%) of examined teenagers declared to experience back pain at least once in their lives. The most of teenagers (117; 53.67%) indicated lumbar spine pain. Girls more often felt spine pain issues in comparison to boys. Short stature of teenagers was often related to back pain occurrence. No correlation between time spent in sitting position and frequency of skeleton axis pain occurrence was noted. Among group of boys a relation between more frequent physical activity and less often spine pain occurrence was observed.

CONCLUSIONS

Spine pain is an important health problem of examined youth, occurring more frequent among girls than boys. Body height correlate negatively with frequency of spine pain occurrence among youth. Despite spending more than 10 hours daily in sitting position by examined youth, it did not affect the frequency of back pain issues occurrence. Higher physical activity of examined boys was related to less often back pains.

Global, Regional, and National Burden of Spine Pain, 1990-2019: A Systematic Analysis of the Global Burden of Disease Study 2019

OBJECTIVE

To describe the global, regional, national, and temporal trends in neck pain (NP) and low back pain (LBP) from 1990 to 2019 and analyze associations with age, sex, and sociodemographic index (SDI).

DESIGN

Temporal trends analyses of the Global Burden of Disease 2019 data for global, regional, and national prevalence, incidence, and years lived with disabilities (YLDs) of NP and LBP from 1990 to 2019.

MAIN OUTCOME MEASURE(S)

The temporal trends in prevalence, incidence, and YLDs of NP and LBP, and associations with age, sex, and SDI.

RESULTS

Globally, the prevalence, incidence, and YLDs of NP and LBP significantly increased; however, the age-standardized rates of NP showed a stable trend, and those of LBP slightly decreased from 1990 to 2019. The burden of NP and LBP was higher in women than in men. Both NP and LBP exhibited similar age-related trends, with the total numbers and rates increasing with age and reaching their highest points in the middle- and old-aged groups, respectively, in 2019. Overall, the prevalence, incidence, and YLDs of NP and LBP were higher in regions with higher SDI over the 3 decades.

CONCLUSIONS

NP and LBP impose significant major public health burden globally. Although both conditions are more frequent in women and middle-aged groups and tend to be prevalent in countries with high SDI, they have distinct temporal and regional patterns. By comprehending temporospatial trends in the disease burden of NP and LBP, policymakers and health care professionals can make future interventions and policies to effectively manage these conditions worldwide as well as to achieve equity in prevention, diagnosis, and treatment.

The Effect of comprehensive rehabilitation on Lithuanian adolescent's nonspecific low back pain, depending on the duration: Nonrandomized single-arm trial

OBJECTIVE

To determine pain and functional changes during comprehensive rehabilitation (CR) in adolescents with nonspecific low back pain (NLBP), and to determine the optimal CR duration.

METHODS

The study included 106 adolescents (39 boys [36.8%], 67 girls [63.2%]), 14 to17 years old, with the following inclusion criteria: duration of NLBP for at least 12 weeks; conservative NLBP treatment was effectless; pain intensity using the visual analogue pain scale (VAS) ≤ 7 points; disrupted daily activities; ability to understand and answer the questions; written consent to participate voluntarily in the study. The pain was assessed using the VAS scale, functional changes were assessed using the Oswestry Disability Index (ODI), 12-Item Short Form Survey, Hospital Anxiety and Depression Scale (HAD), and physical functional capacity and proprioception (Proprio) were assessed using an isokinetic dynamometer. The participants performed a comprehensive pain rehabilitation program consisting of physiotherapy, TENS, magnetotherapy, lumbar massage, and relaxing vibroacoustic therapy. The active CR cycle lasted for 22 sessions (with intermediate measurements after 5 and 16 sessions), after which we performed passive observation for another half a year. Five measurements were performed.

RESULTS

Pain, functional assessment, and physical capacity were improved with CR. Statistically significant improvement became apparent after 5 CR sessions, but statistical and clinical significance became apparent after 16 CR sessions. In the distant period, after the completion of CR, neither statistical nor clinical changes occurred.

CONCLUSIONS

CR is effective in reducing pain, and improving functional state and physical capacity quickly and reliably in 16 CR sessions, which is sufficient to obtain clinically satisfactory CR results. Good results were achieved during CR and neither improved nor deteriorated spontaneously in the distant period. This study shows a possible mismatch between NLBP intensity and impaired functional state in adolescents.

Incidence, prevalence and risk factors for low back pain in adolescent athletes: a systematic review and meta-analysis

OBJECTIVE

To investigate the incidence, prevalence, risk factors and morphological presentations of low back pain (LBP) in adolescent athletes.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

Medline, Embase, CINAHL via EBSCO, Web of Science, Scopus.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Studies evaluating the incidence and/or prevalence of LBP in adolescent athletes across all sports.

RESULTS

There were 80 studies included. The pooled incidence estimate of LBP in adolescent athletes was 11% (95% CI 8% to 13%, I²=0%) for 2 years, 36.0% (95% CI 4% to 68%, I²=99.3%) for 12 months and 14% (95% CI 7% to 22%, I²=76%) for 6 months incidence estimates. The pooled prevalence estimate of LBP in adolescent athletes was 42% (95% CI 29% to 55%, I²=96.6%) for last 12 months, 46% (95% CI 41.0% to 52%, I²=56%) for last 3 months and 16% (95% CI 9% to 23%, I²=98.3%) for point prevalence. Potential risk factors were sport participation, sport volume/intensity, concurrent lower extremity pain, overweight/high body mass index, older adolescent age, female sex and family history of LBP. The most common morphology reported was spondylolysis. Methodological quality was deemed high in 73% of cross-sectional studies and in 30% of cohort studies. Common reasons for downgrading at quality assessment were use of non-validated survey instruments and imprecision or absence of LBP definition.

SUMMARY/CONCLUSION

LBP is common among adolescent athletes, although incidence and prevalence vary considerably due to differences in study methodology, definitions of LBP and data collection.

Association between Physical Fitness and Low Back Pain: The Pepe Cross-Sectional Study

Background: Recent studies have shown that the lifetime prevalence of low back pain (LBP) in schoolchildren aged 10–12 years is 73.6%, and that it appears to have an impact on people’s quality of life. A wide range of risk factors associated with LBP have been studied. However, inconsistent results have been reported. In recent decades, the physical fitness level of children and adolescents has worsened, and the current data on the relationship between muscular fitness and musculoskeletal pain are ambiguous. The purpose of the present study was to analyze the relationship between physical fitness and the occurrence and intensity of LBP. Methods: This cross-sectional study assessed 849 students, aged 10–12 years, from 10 primary schools (fifth and sixth grades) from Majorca (Spain). It was based on two different structured and self-administered questionnaires and a fitness test battery validated for child populations. Results: The results showed that higher levels of VO2Max correspond to less LBP intensity. Additionally, LBP was less prevalent among participants who self-reported more physical activity, and higher VO2Max and higher levels of flexibility were associated with the absence of LBP in bed. Conclusion: These results are of particular importance, as cardiorespiratory fitness is the parameter most closely related to health, and it seems to also be related to LBP-prevention.

Global, regional, and national neck pain burden in the general population, 1990–2019: An analysis of the global burden of disease study 2019

Background

This study describes the global epidemiology and trends associated with neck pain. Global Burden of Disease data collected between 1990 and 2019 were used to determine the global burden of neck pain in the general populations of 204 countries.

Methods

Global, regional, and national burdens of neck pain determined by prevalence, incidence, and years lived with a disability (YLD) from 1990 to 2019 were comprehensively analyzed according to age, gender, and socio-demographic index using the Global Burden of Disease Study 1990 and 2019 data provided by the Institute for Health Metrics and Evaluation.

Results

Globally, in 2019, the age-standardized rates for prevalence, incidence, and YLD of neck pain per 100,000 population was 2,696.5 (95% uncertainty interval [UI], 2,177.0 to 3,375.2), 579.1 (95% UI, 457.9 to 729.6), and 267.4 (95% UI, 175.5 to 383.5) per 100,000 population, respectively. Overall, there was no significant difference in prevalence, incidence, or YLD of neck pain between 1990 and 2019. The highest age-standardized YLD of neck pain per 100,000 population in 2019 was observed in high-income North America (479.1, 95% UI 323.0 to 677.6), Southeast Asia (416.1, 95% UI 273.7 to 596.5), and East Asia (356.4, 95% UI 233.2 to 513.2). High-income North America (17.0, 95% UI 9.0 to 25.4%) had the largest increases in YLD of neck pain per 100,000 population from 1990 to 2019. At the national level, the highest age-standardized YLD of neck pain was found in the Philippines (530.1, 95% UI 350.6 to 764.8) and the highest change age-standardized YLD between 1990 and 2019 was found in the United States (18.4, 95% UI 9.9 to 27.6%). Overall, the global burden of neck pain increased with age until the age of 70–74 years, and was higher in women than men. In general, positive associations between socio-demographic index and burden of neck pain were found.

Conclusions

Because neck pain is a major public health burden with a high prevalence, incidence, and YLD worldwide, it is important to update its epidemiological data and trends to cope with the future burden of neck pain.

Global, regional and national burden of low back pain 1990-2019: A systematic analysis of the Global Burden of Disease study 2019

BACKGROUND

To comprehensively analyze the global level and trends of prevalence, incidence and years lived with disability (YLDs) for low back pain (LBP) from 1990 to 2019 by age, sex and sociodemographic index (SDI).

METHODS

Publicly available modelled data and methods were obtained from the Global Burden of Diseases (GBD) study 2019, and used to evaluate the global burden of LBP through a systematic analysis.

RESULTS

Globally, the age-standardized prevalence, incidence and YLDs rate of LBP were slightly decreased from 1990 to 2019, but the number of the prevalent cases, incident cases and YLDs had substantially increased, and LBP remains the leading cause of YLDs in 2019 worldwide. The number of prevalent cases was increased with age and peaked at the age of 45-54 years for both sexes, and the global prevalence rate was higher in females than in males and increased with age, peaking at the 80-84 age group in both sexes in 2019. Overall, a positive association between the age-standardized YLD rate and SDI was observed over the past thirty years. At the national revel, the United States, Denmark and Switzerland had the three highest levels of age-standardized prevalence, while Zambia, Zimbabwe and Canada showed the highest increase in the age-standardized prevalence during 1990-2019.

CONCLUSIONS

LBP is a major public health issue globally, and its burden remains high. Increasing population awareness about its risk factors and preventive measures for LBP are needed to reduce the future burden of this condition.

THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE

Due to the high prevalence and heavy burden of LBP globally, it is important to update its epidemiological data. This systematic analysis provides researchers and healthcare policy makers with up-to-date, comprehensive and comparable information on global LBP burden, which is of clinical translational significance.

A Comparison between Different Types and Frequency of Physiotherapy Treatment for Children and Adolescents with Postural Problems and Low Back Pain

AIM

To examine the effect of a once-a-week group physiotherapy session in addition to a once-a-month individual physiotherapy treatment, in comparison to a monthly individual physiotherapy treatment.

METHODS

Fifty children and adolescents aged 10-18 years with poor back posture, some of whom had LBP, met individually with a physiotherapist once a month. The intervention group received an additional once-a-week group physiotherapy session for 12 weeks. Thorax curve angle, postural behavior, and low back pain (LBP) were measured before and after intervention.

RESULTS

The thorax curve angle decreased from 39.2 ± 9.3 to 28.2 ± 6.8 (p < 0.001) in the group + individual therapy group and from 38.9 ± 9.3 to 27.9 ± 7.8 in the individual therapy only group (p < 0.001). LBP decreased from 5.6 ± 2.2 to 1.6 ± 1.9 (p < 0.001) and from 5.5 ± 2.1 to 2.8 ± 2.0 (p < 0.001). A significantly greater improvement in postural behavior was found in the group + individual therapy group (p = 0.04). Moreover, attrition rates were lower in the experimental group.

CONCLUSION

A lower-frequency individual physiotherapy treatment for 12 weeks proved as beneficial as the same program with an additional higher-frequency group physiotherapy in improving thorax curve angle and LBP. However, the higher-frequency group physiotherapy in addition to the lower-frequency individual treatment was significantly more effective in improving postural behavior and adherence to treatment.

Motor performance and back pain in children and adolescents: A systematic review

BACKGROUND AND OBJECTIVE

Motor performance during childhood and adolescence is recognized as a relevant determinant of present and future health, but its effects on back pain (BP) remain unclear. In this systematic review, we aimed to identify the association between motor performance and BP in children and adolescents.

DATABASES AND DATA TREATMENT

A literature search was performed in the MEDLINE, Scopus, Embase, SPORTDiscus and CINAHL databases. We included cross-sectional, cohort, case-control and controlled clinical trials (data from control groups). The inclusion criteria were as follows: (a) participants aged 6-19 years; (b) assessment motor performance components; (c) assessment of BP and (d) reported measures of association. The risk of bias was assessed by the Downs and Black instrument and the quality of evidence by the grading of recommendations, assessment, development and evaluation (GRADE).

RESULTS

A total of 2360 articles were identified, 25 of which were included in our systematic review. Of the 25 studies, 19 were evaluated as having a low risk of bias. GRADE indicated that 20 studies presented low or very low quality. Most of the studies evaluated flexibility (n = 16), muscle endurance (n = 18) and muscle strength (n = 9). Aerobic capacity, balance and speed were also examined in some studies (n < 5). Overall, motor performance (flexibility, muscle endurance, muscle strength, aerobic capacity, balance and speed) was not associated with BP. Most of the results were inconsistent because of the lack of studies, risk of bias and low quality of evidence. Only trunk extensor muscle endurance was associated with decreased BP with moderate quality of the supporting evidence. Prospective studies with a low risk of bias are warranted to further clarify this relationship in childhood and adolescence and findings may support more targeted and effective health promotion interventions.

SIGNIFICANCE

This systematic review shows that motor performance (flexibility, muscle endurance, muscle strength, aerobic capacity, balance and speed) was not associated with BP in children and adolescents. Most of the results were inconsistent because of the lack of studies, risk of bias and low quality of evidence. Only trunk extensor muscle endurance was associated with decreased BP with moderate quality of supporting evidence.

Incidence of low back pain and potential risk factors among pharmacists: A population-based cohort study in Taiwan

Low back pain (LBP) is one of the most common symptoms of work-related musculoskeletal disorders in pharmacists. This can impede the physical functions of the body and lead to incapacitation, resulting in significant social and economic burden. This study aimed to investigate the incidence and risk factors that correlate with LBP in Taiwanese pharmacists.A retrospective cohort study was conducted among all registered pharmacists aged 20 to 40 years using the National Health Insurance Research Database (2000-2013) in Taiwan. The LBP diagnosis was confirmed with one episode of hospitalization or at least three claimed outpatient visits for LBP. Data on workplace characteristics as well as comorbidities were also collected for the analyses. A Cox proportional hazard regression was used to estimate the risk factors for LBP.The incidence rate of LBP among pharmacists was 16.60% in this study. Older pharmacists (28.49%; P < .01) and those who worked at district hospitals (23.51%; P < .01) showed a higher proportion of LBP. Furthermore, after adjustment for selected potential confounding factors, female pharmacists [adjusted hazard ratio (aHR): 1.12, 95% confidence interval (95% CI): 1.01-1.24, P = .0354] and pharmacists with diabetes (aHR: 1.55; 95% CI: 1.20-2.01; P = .0008) and gout (aHR: 1.70; 95% CI: 1.37-2.09; P < .0001) had significantly higher risks of LBP.In conclusion, age was positively correlated with LBP, and the workplace was an important factor in the development of LBP in pharmacists. We suggest that pharmacists who work in district hospitals should pay more attention to the development of LBP.

Musculoskeletal Pain and Non-Classroom Teaching in Times of the COVID-19 Pandemic: Analysis of the Impact on Students from Two Spanish Universities

The lockdown, due to the coronavirus, has led to a change in lifestyle and physical activity in Spanish university students. The objective of this study was to analyze the prevalence of musculoskeletal pain and changes in physical activity and self-perceived stress in the student bodies of two Spanish Universities during the lockdown. A cross-sectional study was carried out in a sample of 1198 students (70.6% women). The main instruments used for measuring were the Standardized Kuorinka Modified Nordic Questionnaire and the Perceived stress scale (the questionnaire regarding the practice of physical activity). A reduction in the prevalence of musculoskeletal pain (p < 0.001) was identified in the sample of men and women, an increase (12.5%) in the frequency of carrying out physical activity from moderate to frequent, and the preference for strength training (15.1%), especially among women, was identified. All of this may be taken into account by health institutions when implementing measures to encourage physical activity in both suitable amounts and types, which improves the quality of life of the students.

Motor performance and back pain in children and adolescents: a systematic review and meta-analysis protocol

BACKGROUND

The relationship between motor performance and back pain in children and adolescents remains unclear. This article describes the protocol for a systematic review to summarize the knowledge about the association between motor performance, such as agility, flexibility, balance, strength, muscle endurance, and cardiorespiratory fitness, and back pain. Thus, our aim is to identify the influence of motor performance on back pain among children and adolescents.

METHODS

Two independent researchers will search MEDLINE, Scopus, Embase, SPORTDiscus, and CINAHL databases, with no period or language restrictions. We will include cross-sectional, cohort, case-control, and controlled clinical trial studies based on the following criteria: (a) participants from 6 to 19 years of age, (b) assessment of motor performance, (c) assessment of back pain, and (d) report measures of associations between motor performance and back pain. Study quality and risk of bias will be assessed using an adapted version of the Downs and Black instrument. Grading of Recommendations, Assessment, Development, and Evaluations will be used to assess the strength of the body of evidence. Meta-analyses of association measures will be performed for each type of motor performance, separately for different study types. The results will be reported using forest to show the pooled effect of findings and funnel plots to assess precision of the data. If studies are not homogeneous, results from the meta-analyses will not be reported. Associations will then be synthesized descriptively using a pragmatic approach.

DISCUSSION

This systematic review will provide critical insights into the association between motor performance and back pain among children and adolescents; this information may help support clinical practice guidelines as well as public health programs.

Physical activity and low back pain in children and adolescents: a systematic review

INTRODUCTION

Due to a high prevalence of low back pain (LBP) among children and adolescents, it is significant to seek effective prevention and therapeutic procedures. One idea for the programmes is a potential relation between the occurrence of LBP and the level of physical activity. The aim of this review was to analyse the current knowledge regarding the association between physical activity and LBP among children and adolescents.

METHODS

Publications were retrieved by searching the following databases: PubMed, The Cochrane library, Web of Science, Medline and SportDiscus with Full Text (EBSCO). The search strategy included keywords related to physical activity and LBP. The studies included were assessed for methodological quality. PRISMA guidelines were followed for the systematic review.

RESULTS

The total sample size of the nine included studies consisted of 75,233 subjects, with an age range of 9-19 years. All the studies were assessed to be of high quality. One cohort study and five cross-sectional studies found the association between physical activity and LBP in children and adolescents. The remaining studies found no relationship between physical activity and LBP. These findings showed that both extremes of activity levels (i.e. being very low and very high physically active) are associated with LBP.

CONCLUSION

There is moderate evidence for the association between physical activity and LBP in children and adolescents. The results highlight the need for continued research. It seems that for clear evaluation of the analysed association the prospective cohort studies should be conducted.
