“…After duplicate removal, 897 papers were screened at title/abstract level and 49 full-text articles were assessed for eligibility. In total, 10 articles were included, of which eight investigated the prospective association between physical behaviour and the risk of NP and/or LBP (Ariens et al, 2001;Ariens, Bongers, Hoogendoorn, Wal, & Mechelen, 2002;Hallman, Birk Jorgensen, & Holtermann, 2017;Hallman et al, 2016;Korshøj et al, 2018;Lunde, Koch, Knardahl, & Veiersted, 2017;Sitthipornvorakul, Janwantanakul, & Lohsoonthorn, 2015;Thiese, Hegmann, Garg, Porucznik, & Behrens, 2011), and two articles investigated the effect of physical behaviour on prognosis of LBP (Bousema, Verbunt, Seelen, Vlaeyen, & Knottnerus, 2007;Hendrick et al, 2013). Table 1 provides the main characteristics of the included articles.…”

Background and objective Clinical guidelines recommend physical activity to manage neck pain (NP) and low back pain (LBP). However, studies used to support these guidelines are based on self‐reports of physical behaviour, which are prone to bias and misclassification. This systematic review aimed to investigate associations between objectively measured physical behaviour and the risk or prognosis of NP and/or LBP. Databases and data treatment Literature searches were performed in MEDLINE, Embase and Scopus from their inception until 18 January 2019. We considered prospective cohort studies for eligibility. Article selection, data extraction and critical appraisal were carried out by independent reviewers. Results were stratified on activity/sedentariness. Results Ten articles out of 897 unique records identified met the inclusion criteria, of which eight studied working populations with mainly blue‐collar workers. The overall results indicate that increased sitting time at work reduces the risk of NP and LBP while increased physical activity during work and/or leisure increases the risk of these conditions among blue‐collar workers; however, associations were weak. Physical activity was not associated with prognosis of LBP (no studies investigated prognosis of NP). Most of the included articles have methodological shortcomings. Conclusions This review indicates that, among blue‐collar workers, increased sitting at work may protect against NP and LBP while increased physical activity during work and/or leisure may increase this risk. There was no evidence supporting physical activity as a prognostic factor for LBP. Findings should be interpreted with caution due to the weak associations and few available studies with methodological shortcomings. Significance Based on prospective cohort studies with objectively measured physical behaviour, this review questions the common notion that increased physical activity is associated with reduced risk or better prognosis of NP and/or LBP. We found that, among blue‐collar workers, increased sitting time at work reduces the risk of NP and LBP, whereas physical activity somewhat increases the risk. Despite methodological shortcomings, there was consistency in the direction of the results, although high‐quality articles reported the weakest associations.

“…Over 70% of physiotherapists considered the upright lordotic sitting posture as the optimal posture (82). Major stakeholders in the healthcare systems around the world commonly agree that prolonged sitting is associated with a higher prevalence of LBP (25,(83)(84)(85)(86)(87)(88). Sustained sitting for more than thirty minutes is considered a common aggravating factor for many people with LBP (81), although there is a lack of evidence in support of this concept (89)(90)(91).…”

Background. Musculoskeletal dysfunction is one of the most important occupational health issues. Prolonged sitting may be a risk factor for low back pain (LBP) associated with reduced muscle endurance, although many people with a sedentary lifestyle and sitting-type job report no pain and discomfort in the lumbar region. In the present study, endurance of the core muscles in individuals with sedentary jobs with nonspecific chronic LBP were compared with those without LBP. Objective. The present study compared core muscle endurance in individuals with sedentary jobs with and without nonspecific chronic low back pain. Methods. A total of 50 sedentary staffs were selected and divided into LBP and control group. Trunk muscle endurance was measured in seconds using the McGill's trunk flexor endurance test, the Sorenson's trunk extensor endurance test, and the right and left trunk flexor endurance test (Side-bridge test). Differences between the two groups were analyzed using multivariate general linear models in 2 ways ANOVA. Results. There were no significant between-group differences in the raw endurance of the extensor, flexor, right/ left flexor muscles (P ≥ 0.05). However, there were significant betweengroup differences in some self-reported physical fitness subscales (P < 0.05), duration of sitting at home (P = 0.035), frequency of assuming a slump sitting position (P = 0.049), and sitting with leaning back to the backrest (P = 0.02) at work. We developed uni-and multivariate general linear models, which showed adjustments to these parameters and unmasked fundamental between-group differences in extensor muscle endurance. Conclusions. Our finding does not support the popular opinion that daily sitting-while-at-work for long durations is necessarily associated with LBP. Instead, sitting posture, lower physical fitness levels, and shorter duration of sitting activities at home may be associated with reduced extensor muscle endurance in nonspecific chronic low back pain.

“…The disadvantage of prolonged sitting are increased intra-disc load, weakened posterior lumbar structures, and decreased metabolic exchange [ 25 ]. A previous study suggested that prolonged sitting is a risk factor for LBP [ 26 ]. However, the systematical study does not support the idea that prolonged sitting at work and during leisure time is related to LBP [ 6 ].…”

Study DesignA prospective cross-sectional study.PurposeTo evaluate the risk factors associated with the severity of pain intensity in patients with non-specific low back pain (NSLBP) in Southern China.Overview of LiteratureLow back pain (LBP) is the leading cause of activity limitation and work absence throughout the world, so a firm understanding of the risk factor associated with NSLBP can provide early and prompt interventions that are aimed at attaining long-term results.MethodsParticipants were recruited from January 2014 to January 2016 and were surveyed using a self-designed questionnaire. Anonymous assessments included Short Form 36-Item Health Survey (SF-36) and Visual Analogue Scale (VAS). The association between the severity of NSLBP and these potential risk factors were evaluated.Results A total of 1,046 NSLBP patients were enrolled. The patients with primary school education, high body mass index (BMI), those exposed to sustained durations of driving and sitting, smoking, recurrent LBP had increased VAS and Oswestry Disability Index (ODI) scores with lower SF-36 scores (p <0.01). Workers and drivers compared with waiters and patients who lifted >10 kg objects in a quarter of their work time for >10 years had higher VAS and ODI scores with lower SF-36 scores (p <0.01). Multiple logistic regression showed lower levels of education, LBP for 1–7 days, long-lasting LBP in last year, smoking, long duration driving, and higher BMI were associated with more severe VAS score.Conclusions The severity of NSLBP is associated with lower levels of education, poor standards of living, heavy physical labor, long duration driving, and sedentary lifestyle. Patients with recurrent NSLBP have more severe pain. Reducing rates of obesity, the duration of heavy physical work, driving or riding, and attenuating the prevalence of sedentary lifestyles and smoking may reduce the prevalence of NSLBP.
