Sedentary behavior is associated with musculoskeletal pain in adolescents: A cross sectional study

BackgroundHigh prevalence of back pain has been observed in adolescents. Sedentary behavior (SB) is considered a risk factor for musculoskeletal pain. The association between back pain and SB in the pediatric/adolescent population is not well established. ObjectiveTo investigate the association between SB and low back and neck pain in adolescents according to sex. MethodsThis is a cross-sectional study with children and adolescents aged 10-17 years, randomly recruited from public and private schools in Presidente Prudente, Brazil. All students enrolled in the selected schools were eligible to participate. SB was evaluated by adding the number of hours of use of screen devices, such as television, computer, video game, and smartphone/tablet. To assess neck and low back pain, the Nordic Musculoskeletal Questionnaire was used. Physical activity and socioeconomic status were assessed by the Baecke Questionnaire and the Brazilian Criteria for Economic Classification (ABEP), respectively. Odds ratio (OR) from Binary Logistic Regression in the unadjusted and adjusted model (physical activity, abdominal obesity, and socioeconomic status) showed the relationship between musculoskeletal pain and SB. ResultsA total of 1011 adolescents (557 girls) with a mean ± standard deviation age of 13.2±2.4 years were included. Moderate (OR = 1.80; 95%CI: 1.00, 3.23) and high (OR = 1.91; 95%CI: 1.02, 3.53) SB were associated with neck pain in girls. In boys, moderate SB (OR = 2.75; 95%CI: 1.31, 5.78) were associated with neck pain. Moderate (OR = 2.73; 95%CI: 1.45, 5.02) and high (OR = 2.49; 95%CI: 1.30, 4.76) SB were associated with low back pain only in girls. ConclusionModerate and high SB were associated with neck pain in girls and boys, while moderate and high SB were associated with low back pain only in girls.

Low-back pain in adolescents with an osteopathic component

Low-back pain (LBP) is a common symptom presenting in adolescents. Most back pain in adolescents is benign and musculoskeletal in nature, due to trauma or congenital anomalies. Other less common causes include infection, inflammatory conditions or neoplasm. A comprehensive history and physical focusing on posture, muscle tenderness, range of motion, muscle strength and neurological function is essential in understanding the cause of low-back pain. Identification of risk factors for low-back pain will help the clinician in managing their patient. Treatment includes rest, avoiding activities that cause pain, physical therapy, osteopathic manipulative treatment, limited use of non-steroidal anti-inflammatory drugs and family and patient education. Assessing for warning signs or red flags of serious causes of LBP is a fundamental part of the clinical assessment. Pain that awakens from sleep, pain lasting longer than 4 weeks, sudden onset pain, systemic findings such as fever or weight loss and abnormal neurological findings should warrant immediate evaluation as these may suggest serious infectious conditions, malignancy or fracture. This article presents a comprehensive review of the epidemiology, relevant anatomy, biomechanics, causes and major risk factors for adolescent low-back pain. A diagnostic algorithm utilizing a step-by-step approach is also introduced to aid the clinician in management of the patient. Finally, the article presents guidelines for management of the adolescent with low-back pain including conservative, pharmacologic, as well as the osteopathic approach to treatment. Evidence-based recommendations on osteopathic approach to treatment has been reviewed from meta-analysis data and randomized controlled trials.

Prevalence and Predictors of Scoliosis and Back Pain in 591 Adolescents: A Randomized, Stratified, Cross-Sectional Study in Riyadh, Saudi Arabia.

PurposeOwing to the difficulty of establishing a screening program for scoliosis and back pain, along with their disabling consequences and the lack of local prevalence rates, we sought to study the prevalence of scoliosis and back pain in adolescents in Saudi Arabia and the burden reported by the affected age group on the health system.Materials and methodsA school-based, cross-sectional pilot study covering all school districts in Riyadh, Saudi Arabia, was conducted. Students between 12 and 18 years of age were included. Students with any spinal or neurological disorders were excluded. Physical examinations to screen for scoliosis and student-filled questionnaires to assess back pain and health-related quality of life were performed.ResultsOf the 700 students, 591 met the inclusion criteria. High suspicion of adolescent idiopathic scoliosis (AIS) was considered in 174 students (29.44%). In addition, 45.42% of the students had a history of back pain. The Oswestry Disability Index showed that 87 students had disabilities. The average Scoliosis Research Society-22 score was 3 out of 5. A significant difference was found in the self-image and mental health domains for AIS (p = 0.04, p = 0.02, respectively). Age showed a significant increase in the odds ratio of a positive physical exam for every increase of one year in age (p < 0.01).ConclusionIdentifying the prevalence rates and early associated factors during adolescence would help lower the burden on the health system and benefit public health in general. A nationwide study is required to identify the relationship between scoliosis and back pain.

Effect of low back pain on clinical-functional factors and its associated potential risk of chronicity in adolescent dancers of classical ballet: cross-sectional study

BackgroundLow back pain (LBP) is a common symptom in classical ballet dancers, which can limit their daily activities and dance training routines. The purpose of the study was to verify the association and comparison of clinical-functional outcomes (spine flexibility and foot posture) between different levels of intensity low back pain in adolescents of classical ballet and the potential risk of chronicity using the STarT back tool.MethodsCross-sectional study. Participants: 78 adolescent girls who practice classical ballet were evaluated and divided into groups according to level of low back pain: mild (n = 21), moderate (n = 17), and high (n = 20), and a control group (n = 20). Main outcome measures: Pain, flexibility of the spine (thoracic and lumbosacral), risk of chronicity for low back pain, and foot posture were assessed using the visual analogue scale, clinical tests, STarT back screening tool (SBST) questionnaire, and foot posture index (FPI), respectively.ResultsDancers with high-intensity low back pain showed a potential risk of chronicity by the SBST. The spine pain intensity was not different considering thoracic and lumbosacral flexibility in the sagittal plane, but was different with greater supine FPI when compared to control dancers. Mild low back pain was associated with greater supine FPI. The SBST score was associated with higher exposure time–frequency and time of dancing.ConclusionAdolescents of classical ballet with high-intensity low back pain showed a potential risk of chronicity by the SBST. The level of intensity low back pain did not influence the clinical-functional aspects of spine flexibility in the sagittal plane, but the level of intensity moderate pain promoted changes in foot posture (more supinated). The potential risk of chronicity using the SBST was also associated with higher exposure time–frequency and time of dancing, in adolescents of classical ballet.

Treatment of Unspecific Back Pain in Children and Adolescents: Results of an Evidence-Based Interdisciplinary Guideline

Using a structured approach and expert consensus, we developed an evidence-based guideline on the treatment and prevention of non-specific back pain in children and adolescents. A comprehensive and systematic literature search identified relevant guidelines and studies. Based on the findings of this literature search, recommendations on treatment and prevention were formulated and voted on by experts in a structured consensus-building process. Physical therapy (particularly physical activity) and psychotherapy (particularly cognitive behavioral therapy) are recommended for treating pediatric non-specific back pain. Intensive interdisciplinary treatment programs should be provided for chronic and severe pain. Drug therapy should not be applied in children and adolescents. Further research on non-specific back pain in childhood and adolescence is strongly needed to reduce the imbalance between the high burden of non-specific back pain in childhood and adolescence and the low research activity in this field.

Etiology, Risk Factors, and Diagnosis of Back Pain in Children and Adolescents: Evidence- and Consensus-Based Interdisciplinary Recommendations.

Using a structured approach and expert consensus, we developed an evidence-based guideline on the diagnosis of back pain and the treatment of non-specific back pain in children and adolescents. The first part comprises etiology, risk factors, and diagnosis. The second part, published in the same issue, includes treatment and prevention. A comprehensive and systematic literature search was conducted to identify relevant guidelines and studies. Based on the findings of this literature search, recommendations on risk factors and diagnosis were formulated and voted on by experts in a structured consensus-building process. Notable red flags for specific back pain and evidence-based risk factors for non-specific back pain in children and adolescents were identified. Only three evidence-based recommendations could be formulated for causes, red flags, and risk factors for back pain, while two recommendations are based on expert consensus. Regarding diagnostics, eight expert consensus recommendations and one evidence-based recommendation could be provided. Despite the importance of adequate diagnosis for the treatment of back pain in children and adolescents, results of this work confirm the deficit in research investment in this area.

Lateral bending differentiates early-stage spondylolysis from nonspecific low back pain in adolescents

BackgroundEarly-stage spondylolysis (ESS) is one of the common causes of acute low back pain (LBP) in adolescents. Although accurate diagnosis of ESS is important for providing appropriate treatment, differentiating ESS from other low back disorders is difficult by physical signs alone. ObjectivesTo elucidate the most common characteristic, namely, motion-provoking LBP, in patients with ESS. DesignRetrospective comparative cohort study. MethodWe included and categorized adolescents (n = 112; age, <18 years) with acute LBP (<1 month) into the ESS (n = 71) and nonspecific LBP (NS-LBP) (n = 41) groups based on magnetic resonance imaging (MRI) findings. Patients were evaluated using a visual analog scale (VAS), Oswestry Disability Index (ODI), and degree of pain using a numerical rating scale (NRS) provoked by hyperextension, hyperflexion, right and left rotations, and lateral bending in standing position.; the value were compared between the 2 groups. A cut-off value of significance was obtained using receiver operating characteristic (ROC) analysis. ResultsThe mean scores for VAS and ODI and NRS of each test were as follows (ESS/NS-LBP): VAS, 6.5/6.0; ODI, 19.7/24.6; hyperextension, 4.1/4.1; hyperflexion, 2.4/3.0; rotation, 2.1/2.2; and lateral bending, 2.9/2.2. The ESS group had a significantly greater number of LBP cases provoked by lateral bending than the NS-LBP group. A cut-off lateral bending of 3.5 yielded a diagnosis of ESS. ConclusionsOur results indicate that lateral bending is the greatest motion-provoking characteristic of LBP in patients with ESS.

Prevalence and Characteristics of Back Pain in Children and Adolescents from the Region of Murcia (Spain): ISQUIOS Programme.

Puberty is a vulnerable period for musculoskeletal disorders due to the existence of a wide inter-individual variation in growth and development. The main objective of the present study was to describe the prevalence of back pain (BP) in the past year and month in school-aged children according to sex, age, maturity status, body mass index (BMI) and pain characteristics. This study involved 513 students aged between 9 and 16 years. Anthropometric measures were recorded to calculate the maturity stage of the students using a regression equation comprising measures for age, body mass, body height, sitting height and leg length. An ad hoc questionnaire composed of eight questions was used to describe BP prevalence in school-aged children. The results showed that the prevalence of BP in school-aged children was observed in 35.1% over the last year (45% boys and 55% girls), and 17.3% (40.4% boys and 59.6% girls, with an association found between female sex and BP) in the last month. The prevalence of back pain in the past year and month was higher the older the students were, or the more pubertal development they had experienced. The prevalence of BP in the last year was also higher in those with overweight or obesity. After adjustment for sex, there was an association between BP and older age and higher BMI in boys and an association between BP and higher pubertal development in girls. In summary, the present study showed that the prevalence of BP was related to the maturity stage and weight of the participants, with different prevalence patterns found according to sex.

Incidence and factors associated with low back pain in adolescents: A prospective study

BackgroundLow back pain (LBP) is a common complaint among children and adolescents and can negatively impact their physical and mental health. Although previous studies investigating the incidence of low back pain (LBP) in children and adolescents have been performed in high income countries, it is unclear whether countries such as Brazil would show similar incidence rates. ObjectiveTo determine the incidence and to identify predictors of new episodes of LBP in high school students. MethodsThis is a 1-year longitudinal study of high school students from public schools in the city of Bauru, Sao Paulo. Collected clinical data were: demographic and socioeconomic factors, information on the use of electronic devices, mental health status (the Strengths and Difficulties Questionnaires), level of habitual physical activity (Baecke Physical Activity Questionnaire), and incidence of LBP (measured with question about LBP in the past 12 months and the Nordic Musculoskeletal Questionnaire). Descriptive analysis and bivariate and multivariate logistic regressions were performed. ResultsThe cumulative incidence of new LBP episodes for the total cohort of 757 high school students was 18.9% (95% CI: 16.2, 21.8). The cumulative incidence was 14.8% (95% CI: 11.7, 18.5) for male students and 24.1% (95% CI: 19.8, 29.9) for female students. Being a female student (OR = 1.78; 95% CI: 1.23, 2.59), sitting posture while using tablet (OR = 4.34; 95% CI: 1.19, 16.60), daily time spent on tablet (OR = 3.21; 95% CI: 1.41, 7.30), daily time spent on mobile phone (OR =1.49; 95% CI: 1.11, 2.00), lying posture while using mobile phone (OR = 1.49; 95% CI: 1.05, 2.12), and mental health status (OR = 2.81; 95% CI: 1.76, 4.48) were identified as predictor variables. ConclusionOur findings showed that one in five high school students reported having a LBP episode over the last year. The predictors found to be associated with low back pain include those related to sex, time and posture while using electronic devices, and mental health status.

Association of sedentary behavior and early engagement in physical activity with low back pain in adolescents: a cross-sectional epidemiological study.

To investigate the association of sedentary behavior and physical activity from childhood to adolescence with prevalence of low back pain in adolescents. In addition, we also explored whether sleep quality influences this association. This is a cross-sectional epidemiological study. Participants (aged 10-17years) were recruited from public and private schools in Brazil. Sedentary behavior and previous and current engagement in physical activity were assessed through questionnaires. Low back pain and sleep quality were assessed by the Nordic questionnaire and Mini-Sleep Questionnaire, respectively. Sex, age, body mass index, abdominal obesity, socioeconomic status and sleep quality were used as potential confounders. Binary logistic regression models were used to generate values of odds ratio(OR) and 95% confidence intervals (95%CI). A total of 1,001 (44,5% boys; n = 446) were included. Overall prevalence of low back pain was 18%, with higher rates among inactive and sedentary participants. Physical inactivity from childhood to adolescence in combination with high sedentary behavior doubled the likelihood of having low back pain (OR = 2.40 [95%CI: 1.38-4.18]), independent of potential confounders. Sleep quality attenuates, but not eliminates, this association (OR = 2.19 [95%CI: 1.25-3.84]). Being inactive from childhood to adolescence in combination with high sedentary behavior is associated with low back pain in adolescents. Sleep quality seems to attenuate, but not eliminate, this association.

Prevalence of Back Pain and Idiopathic Scoliosis in Adolescents From the Semiarid Region of Brazil: A Cross-sectional Study

ObjectiveThe purpose of this study was to estimate the prevalence of adolescent idiopathic scoliosis (AIS), and back pain and its risk factors, in schoolchildren from the semiarid region of Brazil. MethodsA total of 520 adolescents aged 10 to 16 years old were assessed. The students were administered the self-reported Back Pain and Body Posture Evaluation Instrument questionnaire. The screening for AIS included measuring the angle of trunk rotation using a scoliometer in the Adams forward-bend test. Participants with an angle of trunk rotation ≥ 7° were referred for radiography. The prevalence ratio was estimated by multivariable analysis using a Poisson regression model (α = 0.05). ResultsAmong the participants, 3.1% (95% confidence interval, 3.2%-6.9%) had a confirmed AIS diagnosis: 1.9% girls and 1.1% boys. There was no difference between boys and girls in AIS prevalence. The prevalence of back pain in the previous 3 months was 63.7% (95% confidence interval, 59.5%-67.7%), at a moderate level (visual analog scale = 3.83; 95% confidence interval, 3.57-4.08). Multivariable analysis showed that back pain is associated with postural variables, sex, and age. ConclusionThe prevalence of AIS in the semiarid region of Brazil was 3.1%, and that of back pain was 63.7%. Only body mass index was different between adolescents with and without AIS, with those with AIS having a lower mean body mass index. Back pain was higher in girls and increased in older adolescents. Furthermore, behavioral and postural habits and hereditary factors were associated with an increased chance of back pain.

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

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. 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 6-19years; (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). A total of 2360 articles were identified, 25 of which were included in our systematic review. Of the 25studies, 19 were evaluated as having a low risk of bias. GRADE indicated that 20studies 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. 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.

Cross-National Trends of Chronic Back Pain in Adolescents: Results From the HBSC Study, 2001-2014

Chronic back pain is a common problem that negatively impacts the wellbeing of many adolescents. Prior research suggests that the prevalence of chronic back pain has increased over the last decades, but research on this issue is scarce, single country-based, and has yielded inconsistent results. This study aimed to examine trends in the prevalence of chronic back pain over time in adolescents aged 11, 13 and 15, using data from the Health Behavior in School-aged Children (HBSC) survey. We conducted a secondary analysis of data from 650,851 adolescents, retrieved from four waves (2001/02, 2005/06, 2009/10 and 2013/14) of HBSC data from 33 countries or regions. The prevalence of back pain was higher (1) in each successive survey over time (18.3% in 2001/02, 19.3% in 2005/06, 20.4% in 2009/10 and 21.6% in 2013/14), (2) in girls (21.9%) compared to boys (17.8%), and (3) in older adolescents compared to younger ones (14.5% in 11-year-olds, 19.6% in 13-year-olds and 25.5% in 15-year-olds). The increase in prevalence from 2001/02 to 2013/14 was more marked in older girls compared to younger girls, and in older boys compared to younger boys, and it ranged between 1% for 11-year-old boys and 7% for 15-year-old girls. More resources should be allocated to the prevention and treatment of chronic back pain in adolescents, especially for older girls. PerspectiveThe prevalence of chronic back pain in adolescents has increased from 2001-2002 to 2013-2014, especially in older adolescent girls. These findings underline the need of further research to understand the reason behind the increasing trend, and what programs are better suited to prevent chronic back pain among adolescents.

Back School Postural Education Program: Comparison of Two Types of Interventions in Improving Ergonomic Knowledge about Postures and Reducing Low Back Pain in Adolescents.

This study aimed to compare the impact of two Back School Postural Education Programs on improving ergonomic knowledge of postures adopted at school and home, as well as on reducing low back pain (LPB) in adolescents. The sample was constituted by 153 students, aged 10–16 years, with 96 (62.7%) girls, divided into 2 intervention groups (GA, GB). Two tests (theoretical and practical) and LBP questionnaire were applied 1 week before and 1 year after the end of the program. In GA, three sessions were performed for each class separately, on theoretical and practical issues, lasting 45 min and at intervals of 1 week, and in GB, only one theoretical session (90 min) was given to all students. Statistically differences on GA were obtained between the values 1 week before and after 1 year of evaluation in both theoretical and practical tests (p ≤ 0.001). In GB, only the values of the practical test present a statistical difference (p ≤ 0.001). GA obtained higher values on both tests after 1 year of follow-up compared with GB (p ≤ 0.001). The number of students with LBP decreased on GA (p ≤ 0.001). The program with longer duration, higher weekly frequency, and more practical and individualized character promotes better effects.

Transforaminal lumbar interbody fusion versus posterolateral fusion for the treatment of low-grade isthmic spondylolisthesis in adults

Background Isthmic spondylolisthesis means slippage of one vertebra relative to the next caudal vertebra as a result of an abnormality in the pars interarticularis. Isthmic spondylolisthesis has three subtypes: subtype A in which there is stress fracture of the pars (spondylolysis), subtype B in which the pars is elongated, and subtype C in which there is acute fracture of the pars. Isthmic spondylolisthesis is the most common cause of low back pain in adolescents. Spinal fusion is the mainstay of the surgical treatment of low-grade isthmic spondylolisthesis. Spinal fusion can be achieved by posterolateral fusion (PLF) or circumferential fusion. The three basic techniques for circumferential fusion include anterior lumbar interbody fusion, posterior lumbar interbody fusion, and transforaminal lumbar interbody fusion (TLIF). Patients and methods Fifty patients with low-grade isthmic spondylolisthesis managed with spinal fusion at the Zagazig University Hospital. Patients were divided into two groups: group I included patients managed by TLIF and group II included patients managed by PLF. The mean age of patients was 34.6 years (range: 26–43 years) in group I and 36.8 years (range: 28–46) in group II. Sex distribution was nine males and 16 females in group I and seven males and 18 females in group II. Exclusion criteria included patients with high-grade spondylolisthesis, traumatic spondylolisthesis, degenerative spondylolisthesis, neoplastic spondylolisthesis, patients with acute or chronic infection, and congenital malformation. Results No patients were dropped in the follow-up. In both groups, the mean visual analog scale (VAS) for back pain and leg pain and the Oswestry disability index (ODI) showed statistically significant difference between the values obtained preoperatively and the values obtained at the 1-year follow-up visit. In comparison between both groups for the change in the VAS for back and leg pain and ODI score, group I gave a significant difference regarding the change in the VAS for back pain compared to group II. However, the change in the VAS for leg pain and ODI was not statistically significant. Conclusion Both TLIF and PLF are effective options for the treatment of low-grade isthmic spondylolisthesis in adults. However, TLIF gives better clinical outcome, so it is considered a better option.

Inter-rater Reliability of the McKenzie Method of Mechanical Diagnosis and Therapy for the Provisional Classification of Low Back Pain in Adolescents and Young Adults

ABSTRACT Objective To investigate the inter-rater reliability of Mechanical Diagnosis and Therapy (MDT)-trained Diplomats in classifying adolescents and young adults with lumbar pain. Methods Forty-three participants (mean age 15 ± 2 years) with lumbar pain, with or without lower extremity symptoms, were assessed simultaneously by three MDT Diploma holders and classified into one of three groups: 1) Derangement, 2) Dysfunction, 3) Postural/OTHER. Inter-rater reliability was calculated using the Fleiss kappa statistics with 95% confidence intervals (CI). Analyses were repeated with the younger (11 to 15 years old) and older (16 to 21 years old) age groups. Results There was moderate reliability (Fleiss kappa = 0.50, 95% CI = 0.45 to 0.54) for the entire sample, which was statistically significant (p < 0.001). There was good reliability in older participants (Fleiss kappa = 0.63, 95% CI = 0.57 to 0.70), but poor reliability in younger participants (Fleiss kappa = 0.33, 95% CI = 0.27 to 0.39). There was 100% agreement in classifications among assessors for 70% of participants. Discussion The MDT system has moderate reliability when classifying lumbar pain in adolescents and young adults. Future reliability studies may include a balanced group for classifications or a second session.

Recurrent back pain in adolescents with different types of online behavior

Recurrent back pain in adolescents with different types of online behavior

Early life chronic inflammatory conditions predict low back pain in adolescence and young adulthood.

Associations between inflammatory conditions and low back pain (LBP) have been found frequently in older populations. However, the nature of these relationships in younger populations is unknown. This study aimed to investigate the associations between early life chronic or recurrent inflammatory conditions and impactful LBP in adolescence and young adulthood. In this longitudinal study, we used data from the Raine Study Gen2 participants at the 1, 2, 3, 5, 8, 10, 14, 17, 20 and 22-year follow-ups (N=2,868). Data were collected on inflammatory conditions from 1 to 22years of age and occurrences of impactful LBP from 14 to 22years of age. Longitudinal and cross-sectional associations between inflammatory conditions and impactful LBP occurrence were examined. Potential dose-response relationships between the number of inflammatory conditions and impactful LBP were also assessed. Logistic regression models were used in the analysis. Participants with respiratory or atopic conditions during childhood had increased odds of future impactful LBP in adolescence and young adulthood (odds ratio (OR) [95% confidence interval (CI)] = 1.29 [1.07, 1.54] and 1.23 [1.02, 1.49], respectively). There were cross-sectional associations between inflammatory conditions including respiratory, skin, musculoskeletal, autoimmune and atopic conditions, with impactful LBP. Participants with two illnesses and three or more illnesses had an increased odds (OR [95% CI] =1.68 [1.30, 2.18] and OR [95% CI] =2.12 [1.54, 2.89], respectively) of reporting impactful LBP. Overall, longitudinal and cross-sectional associations of respiratory and atopic conditions with impactful LBP in adolescence and young adulthood were identified. More evidence is needed to determine whether there is a causal relationship between chronic inflammatory conditions and impactful LBP. Low back pain (LBP) is a prominent and significant health problem and associations between inflammatory conditions and LBP have been found frequently in older populations. We found that children with respiratory or atopic conditions and those with several chronic inflammatory conditions are at increased odds of impactful LBP in adolescence and young adulthood. In clinical practice and future research, there is a need to consider comorbidities also in younger populations.

Low back pain in adolescents and association with sociodemographic factors, electronic devices, physical activity and mental health

ObjectivesTo determine the prevalence of low back pain and to analyze the association with the individual, sociodemographic variables, electronic devices, habitual practice of physical activity, and mental health problems. MethodsCross‐sectional study with 1,628 students in public schools in the city of Bauru, SP, Brazil. The following data were collected: 1. demographic and socioeconomic aspects; 2. Use of electronic devices; 3. habitual physical activity level (Baecke); 3. mental health (SDQ). 4. low back pain (Nordic Questionnaire). Descriptive analyzes and bivariate and multivariate logistic regression were used. ResultsThe overall prevalence of low back pain was 46.7% (95% CI: 44.27 to 49.11); men showed a prevalence of 42.0% (95% CI: 36.63 to 43.41) and women 58.0% (95% CI: 49.73 to 56.51), a statistically significant difference. The variables associated with pain in the low back region were: female gender (PR = 1.70), daily TV use for more than 3hours (PR = 1.17), use of laptop computer (PR = 1.40), use of the cell phone in the supine position (PR = 1.23), use of the cell phone in semi‐supine position (PR = 1.49), daily cell phone use for more than 3hours (PR = 1.36), use of tablet (PR = 1.67), daily tablet use for more than above 3hours (PR = 1.46), and clinically important mental health problems (PR = 2.62). ConclusionThere is a high prevalence of low back pain in high school students and striking association with female sex, electronic devices, and mental health problems.

Back Pain in Children and Adolescents.

Back pain has long been considered an uncommon complaint in the pediatric population. When present, teaching had been that pediatric back pain almost always has a diagnosable cause, many of which are progressive and potentially debilitating. Recent evidence has suggested that pediatric back pain is not only more common than once thought but also, within certain populations, benign and idiopathic. This, in turn, places an increasing amount of pressure on pediatricians to accurately assess and manage their patients presenting with complaints of back pain. The aim of this article is to serve as a review of the current literature on pediatric back pain. The article reviews the epidemiology, basic anatomy, and important elements of a history and examination, which should be considered when a child presents complaining of back pain. Last, a common differential diagnosis with evaluation and management is also given to help guide pediatricians through their medical decision making.
