Low back pain and physical activity--A 6.5 year follow-up among young adults in their transition from school to working life

Competences to self-manage low back pain among care-seeking adolescents from general practice - a qualitative study

BACKGROUND

There is limited knowledge about when and how adolescents with low back pain (LBP) interact with health care providers. This limits our understanding of how to best help these young patients. This study aimed to understand when and how care-seeking adolescents with LBP interact with health care providers and which health literacy competencies and strategies do they use to self-managing their LBP.

METHOD

Ten semi-structured interviews (duration 20-40 min) were conducted online among adolescents aged 15-18 with current or recent LBP (pain duration range; 9 months - 5 years). The interview guide was informed by literature on health literacy and self-management in patients. We conducted a semantic and latent thematic data analyses.

RESULTS

Three major themes emerged from the analysis: (1) Self-management, (2) Pain and Function, and (3) Communication. All adolescents were functionally limited by their pain but the main reason to consult a health care provider was an increase in pain intensity. Many were able to navigate the healthcare system, but experienced difficulties in communicating with health care providers, and many felt that they were not being taken seriously. Their first line self-management option was often over-the-counter pain medicine with limited effects. Most adolescents expressed a desire to self-manage their LBP but needed more guidance from health care providers.

CONCLUSION

Adolescents with LBP seek care when pain intensifies, but they lack self-management strategies. Many adolescents want to self-manage their LBP with guidance from health care providers, but insufficient communication is a barrier for collaboration on self-management.

Fear Avoidance Predicts Persistent Pain in Young Adults With Low Back Pain: A Prospective Study

OBJECTIVES

To (1) quantify relationships between low back pain (LBP) symptoms, physical activity, and psychosocial characteristics in young adults and (2) identify subclasses of young adults with distinct pain trajectories.

DESIGN

Prospective cohort study with 12-month follow-up.

METHODS

One hundred twenty adults (mean ± SD age, 20.8 ± 2.6 years; 99 women) participated. Participants completed a baseline survey that measured anxiety, depression, fear avoidance, quality of life, and history and impact of any LBP. Participants completed follow-up surveys every 3 months for 1 year. Subclasses based on pain trajectories over time were identified using latent class analysis, and predictors of class membership at baseline were assessed.

RESULTS

Individuals with LBP at baseline had lower physical quality-of-life scores than back-healthy participants (P = .01). Subclass 1 (25% of individuals with LBP) had persistent moderate-to-high pain intensity over the 1-year study period. Subclass 2 (75% of individuals with LBP) had significantly improving pain over the 1-year study period. Higher fear avoidance (physical activity subscale) and pain interference at baseline were associated with greater odds of membership in subclass 1 (odds ratio = 1.2; 95% confidence interval: 1.0, 1.3 and odds ratio = 1.4; 95% confidence interval: 1.1, 1.6, respectively).

CONCLUSION

Most young adults with LBP had symptoms that improved over time. Levels of fear avoidance and pain interference may help to identify individuals at risk of persistent pain early in the lifespan. J Orthop Sports Phys Ther 2021;51(8):383-391. Epub 15 May 2021. doi:10.2519/jospt.2021.9828.

Association between lifestyle and musculoskeletal pain: cross-sectional study among 10,000 adults from the general working population

BACKGROUND

Work-related musculoskeletal pain is a major cause of work disability and sickness absence. While pain is a multifactorial phenomenon being influenced by work as well as lifestyle, less is known about the association between specific lifestyle factors and the type of musculoskeletal pain. The aim of the study was to investigate if a dose-response association existed between lifestyle factors and musculoskeletal pain intensity in the low back and neck-shoulder.

METHODS

Currently employed wage earners (N = 10,427) replied in 2010 to questions about work environment, lifestyle and health. Logistic regression analyses adjusted for various confounders tested the association of alcohol intake, physical activity, fruit and vegetable intake, and smoking (explanatory variables) with low back pain and neck-shoulder pain intensity (outcomes variables, scale 0-9, where ≥4 is high pain).

RESULTS

The minimally adjusted model found that physical activity and fruit and vegetable intake were associated with lower risk of musculoskeletal pain, while smoking was associated with higher risk of musculoskeletal pain. In the fully adjusted model, physical activity ≥5 h per week was associated with lower risk of low back pain and neck-shoulder pain with risk ratios (RR) of 0.95 (95% CI 0.90-1.00) and 0.90 (95% CI 0.82-0.99), respectively. No association was found between alcohol intake and pain.

CONCLUSION

Being physically active associated with lower risk of having musculoskeletal pain, while smoking habits and healthy eating were associated with higher pain when adjusting for age and gender. Considering the continuously increasing retirement age in many societies, initiatives to promote healthy habits should still be a political priority to help the workers to stay healthy and cope to their work.

Rapid Assessment of Physical Activity and its Association Among Patients with Low Back Pain

Objective To evaluate the physical activity levels in individuals with low back pain (LBP) and its relationship with various demographic variables like age, gender, number of days off from work and nature of occupation. Methodology This was a cross-sectional study that was done in a private hospital in Jeddah, Saudi Arabia. Data was collected between the periods of 2017-2018. All patients who attended the orthopedic outpatient department (OPD) with LBP were included in this study and were requested to fill the Rapid Assessment of Physical Activity (RAPA) questionnaire. The gathered data were analyzed through the Statistical Package for Social Sciences (SPSS Inc., Chicago, IL), version 23. One-way analysis of variance (ANOVA) was used to compare the mean difference in RAPA scores between genders, age, occupation and number of leaves from their work.  Results Three hundred sixty patients visited the orthopedic OPD with the primary complaint of LBP, 318 (88.3%) were male whereas 42 (11.7%) were female. The study revealed that among these patients, 117 (32.5%) led sedentary while 176 (48.9%) led an underactive lifestyle. Furthermore, 246 (68.3%) patients did not do any activity that increases their muscle strength and flexibility. Conclusion The findings of this study revealed that low physical activity is prevalent in patients with LBP. Therefore, the importance of physical activity should be highlighted in order to prevent chronic diseases like LBP.

Risk factors for episodes of back pain in emerging adults. A systematic review

BACKGROUND AND OBJECTIVE

The transition from adolescence to adulthood is a sensitive period in life for health outcomes, including back pain. The objective was to synthesize evidence on risk factors for new episodes of back pain in emerging adults (18-29 years).

METHODS

The protocol was registered in PROSPERO (CRD42016046635). We searched Medline; EMBASE; AMED and other databases up to September 2018 for prospective cohort studies that estimated the association between risk factor(s) and self-reported back pain. Risk factors could be measured before or during the age range 18-29 years, and back pain could be measured during or after this age range, with at least 12 months between assessments. Risk factors assessed in ≥3 studies were summarized. Risk of bias was assessed using a 6-item checklist.

RESULTS

Forty-nine studies were included with more than 150 different risk factors studied. Nine studies had low risk of bias, 26 had moderate and 14 had high risk of bias. Age, sex, height, body mass index (BMI), smoking, physical activity level, a history of back pain, job satisfaction and structural imaging findings were investigated in three or more studies. History of back pain was the only risk factor consistently associated with back pain after adjustment (nine studies).

CONCLUSION

There is moderate quality evidence that a history of back pain is a risk factor for back pain. There are inconsistent associations for age, sex, height, BMI, smoking and activity level. No associations were found between job satisfaction and structural imaging findings and back pain.

SIGNIFICANCE

Emerging adulthood is a transitional period of life with changes in life style, potentially influencing future musculoskeletal health. This systematic review included 49 articles evaluating more than 150 potential risk factors for back pain, one of the most prevalent musculoskeletal disorders. No consistent results were found for life style factors such as physical activity level or BMI, both highlighted as important risk factors in previous literature. Importantly, a previous episode of back pain was a consistent risk factor for a new episode of back pain across several studies, and further investigation of risk factors for the first back pain episode is needed.

Poor prognosis of child and adolescent musculoskeletal pain: a systematic literature review

OBJECTIVES

To identify baseline patient characteristics that are (1) associated with a poor outcome on follow-up regardless of which treatment was provided (prognosis) or (2) associated with a successful outcome to a specific treatment (treatment effect modifiers).

DESIGN

Systematic literature review according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

DATA SOURCES

Medline, Embase, Cinahl, Web of Science, Cochrane, SportDiscus, OT Seeker and PsychInfo were searched for prospective cohort studies up to February 2019 without limitation in publication date.

ELIGIBILITY CRITERIA

Prospective cohort studies reporting either prognostic factors or treatment effect modifiers on persistent musculoskeletal pain in 0-year-old to 19-year-old children and adolescents. Pain caused by tumours, fractures, infections, systemic and neurological conditions were excluded.

OUTCOME MEASURES

Our primary outcome was musculoskeletal pain at follow-up and identification of any baseline characteristics that were associated with this outcome (prognostic factors). No secondary outcomes were declared.

METHOD

Two reviewers independently screened abstracts and titles. We included prospective cohort studies investigating the prognosis or treatment effect modifiers of 0-year-old to 19-year-old children and adolescents with self-reported musculoskeletal pain. Risk of bias assessment was conducted with the Quality in Prognostic Studies tool.

RESULTS

Twenty-six studies yielding a total of 111 unique prognostic factors were included. Female sex and psychological symptoms were the most frequent investigated prognostic factors. Increasing age, generalised pain, longer pain duration and smoking were other identified prognostic factors. No treatment effect modifiers were identified.

CONCLUSION

Several prognostic factors are associated with a poor prognosis in children and adolescents with musculoskeletal pain. These prognostic factors may help guide clinical practice and shared decision-making. None of the included studies was conducted within a general practice setting which highlights an area in need of research.

Million Visual Analogue Scale Questionnaire: Validation of the Persian Version

Study Design

Descriptive cross-sectional study.

Purpose

To validate the Persian version of the Million Visual Analogue Scale Questionnaire (MVAS), a self-administered low back pain (LBP) questionnaire.

Overview of Literature

The majority of LBP questionnaires translated into Persian evaluate the impact of LBP on daily living. The MVAS is one of the most commonly used self-administered LBP questionnaires, and was developed to assess a different direction and effect of activities of daily living on LBP intensity.

Methods

The questionnaire was translated into Persian with the forward-backward method and was administered to 150 patients randomly sampled from an occupational medicine clinic in Tehran in 2017.

Results

Cronbach’s alpha for all subscales ranged between 0.670 and 0.799. Confirmatory factor analysis showed adequate construct validity of the Persian version of the MVAS, with root mean square error of approximation 0.046, goodness of fit index 0.902, and comparative fit index 0.969. Other indexes were satisfactory.

Conclusions

The Persian MVAS is a valid and reliable instrument that can assess the effect of various daily activities on the intensity of LBP.

Influence of family history on prognosis of spinal pain and the role of leisure time physical activity and body mass index: a prospective study using family-linkage data from the Norwegian HUNT study

OBJECTIVES

To investigate the influence of parental chronic spinal pain on prognosis of chronic spinal pain in adult offspring, and whether offspring physical activity level and body mass index (BMI) modified this association.

DESIGN

Prospective cohort study.

SETTING

We used family-linked longitudinal data from the Norwegian HUNT study collected in HUNT2 (1995-1997) and HUNT3 (2006-2008).

PARTICIPANTS

A total of 1529 offspring who reported spinal pain in HUNT2 were linked with parental data and followed up in HUNT3.

OUTCOMES

We estimated relative risk (RR) with 95% CI for recovery from chronic spinal pain, and also from activity limiting spinal pain, in offspring related to chronic spinal pain in parents. We also investigated whether offspring leisure time physical activity and BMI modified these intergenerational associations in spinal pain.

RESULTS

A total of 540 (35%) offspring were defined as recovered after approximately 11 years of follow-up. Offspring with both parents reporting chronic spinal pain were less likely to recover from chronic spinal pain (RR 0.83, 95% CI 0.69 to 0.99) and activity limiting spinal pain (RR 0.71, 95% CI 0.54 to 0.94), compared with offspring of parents without chronic spinal pain. Analyses stratified by BMI and physical activity showed no strong evidence of effect modification on these associations. However, offspring who were overweight/obese and with both parents reporting chronic spinal pain had particularly low probability of recovery from activity limiting spinal pain, compared with those who were normal weight and had parents without chronic spinal pain (RR 0.57, 95% CI 0.39 to 0.84).

CONCLUSION

Offspring with chronic spinal pain are less likely to recover if they have parents with chronic spinal pain, particularly if offspring are overweight/obese.

Association between objectively measured physical activity and body mass index with low back pain: a large-scale cross-sectional study of Japanese men

BACKGROUND

The relationship between the combination of physical activity (PA) and body mass index (BMI) with low back pain (LBP) is unclear. The present study offers a cross-sectional assessment of how combinations of PA and BMI are related to LBP in Japanese men.

METHODS

Participants were 4022 Japanese men (mean age = 47) who underwent regular clinical examinations. PA was measured using a uniaxial accelerometer and divided into tertiles (PA_high, PA_middle, PA_low). A self-administered questionnaire was used to report on persistent LBP experience, drinking and smoking habits, and any existing lifestyle diseases. After covariance adjustment, a logistic regression model was used to assess how combinations of PA and BMI are related to persistent LBP.

RESULTS

428 of the participants had persistent LBP. A clear negative dose-response relationship was found between PA levels and persistent LBP (P for linearity = 0.012). Regarding BMI, odd ratios were shown to be higher in the overweight/obese category (BMI ≥ 25 kg/m²) than for the normal weight category (BMI < 25 kg/m²). When the PA_high was taken as the reference in the normal weight category, odds ratios for PA_low and PA_middle in the normal weight category were shown to be high. Moreover, in the overweight/obese category, odd ratios for every fitness level were also high as for the normal weight category.

CONCLUSION

The present study showed that both PA and BMI are related to persistent LBP. Also, the prevalence of persistent LBP became higher when PA_low and high BMI are combined rather than the group of PA_high and low BMI combination.

Participation in physical activity and back pain among an elderly population in South Asia

Introduction

Globally, chronic back pain is one of the most commonly encountered medical conditions among an elderly population with significant bearings on health, functional mobility and general well-being.

Objective

To estimate the burden of chronic back pain and its association with physical activity (PA) among population aged 50 years and above in Bangladesh, India, Nepal, Pakistan and Sri Lanka.

Methods

Cross-sectional data on 8502 men and women aged 50 years and above were collected from the World Health Survey (2002). Three forms of PA were considered – vigorous physical activity (VPA), moderate physical activity (MPA) and walking. Odds ratios (ORs) of the association between self-reported back pain and VPA, MPA and walking were calculated by using generalized estimating equations.

Results

The prevalence of back pain was, respectively, 64.8%, 19.8%, 69.5%, 40.6% and 36.2% in Bangladesh, India, Nepal, Pakistan and Sri Lanka. No significant association between back pain and VPA was observed among men in any of the countries. In India, Pakistan and Sri Lanka, the odds of suffering from back pain were, respectively, 29%, 2.5 times and 59% higher among women who almost never took MPA. In India, taking MPA for few days a week and almost never was associated with, respectively, 38% (OR=1.38; 95% confidence interval [CI]=1.017–1.876) and 56% (OR=1.564; 95% CI=1.003–2.438) higher odds of reporting back pain. Walking almost never was also associated with, respectively, 83% (OR=1.829; 95% CI=1.14–2.934) and 2.9 times (OR=2.854; 95% CI=1.419–5.738) higher odds of reporting back pain among men in Nepal and Pakistan, respectively.

Conclusion

Though the relationship was not consistent across sex and countries, results indicate that inadequate or nonparticipation can substantially increase the likelihood of suffering from back pain among an elderly population in this region. Further research is needed to better understand this relationship and the potential of exercised-based strategies to prevent and treat back pain among elderly persons.

Association between V̇O2max, handgrip strength, and musculoskeletal pain among construction and health care workers

Background

Construction and health care workers have a high prevalence of musculoskeletal disorders, and they are assumed to have physically demanding jobs. Profession- and gender-specific associations between individual capacity and musculoskeletal pain have not been sufficiently investigated. The main aim of this study was to examine the association between individual capacity (maximal oxygen uptake (V̇O_2max) and handgrip strength) and musculoskeletal pain among construction and health care workers.

Methods

This cross-sectional study examined 137 construction and health care workers (58 women and 79 men) with a mean age of 41.8 years (standard deviation 12). Aerobic capacity was indirectly assessed by the Åstrand cycle test, and strength was assessed by a handgrip test. Musculoskeletal pain was described by total pain, divided into neck, shoulder, and low back pain, during the last 12 months, and it was dichotomized in below or above 30 days. Logistic regression was used to analyse the associations between V̇O_2max, strength, and musculoskeletal pain in the total study sample and separately for construction and health care workers. Analyses were adjusted for age, gender, body mass index (BMI), and selected mechanical and psychosocial factors.

Results

Every second participant (51.8%) reported pain in either neck, shoulders or low back for more than 30 days during the last 12 months. Among the health care workers, a small but significant association was found between a high V̇O_2max, high handgrip strength, and a low level of musculoskeletal pain. No association was found for the construction workers.

Conclusions

An association between V̇O_2max, handgrip strength, and musculoskeletal pain was found for health care workers but not for construction workers. These results indicate that activities promoting individual capacity may reduce musculoskeletal pain for health care workers.
