Abstract
BACKGROUND Lumbar intervertebral disc height loss has been associated with spinal height change (SHC) and low back pain (LBP), including stenosis. Non-invasive methods to improve disc height loss require forms of lying down, which are unconducive to computer work. OBJECTIVE Intermittent vertical traction (VT) integrated with seated computer work may provide ergonomic alternatives for increasing SHC to promote LBP relief. The primary aim was to develop and introduce a safe VT prototype and dosage to induce and measure SHC. Prototype comfort and LBP ratings were exploratory secondary aims. METHODS Forty-one participants were stadiometry-measured for pre- and post-intervention SHC from seated VT at 35% body weight removed, supine lying (SL), and sitting at a computer (SIT) without VT. Pain ratings were recorded for those self-reporting LBP. VT prototype evaluations were compiled from a 3-question, 7-point Likert-style survey. RESULTS SHC increased by 3.9 ± 3.4 mm in VT, 1.7 ± 3.4 mm in SIT, and 4.3 ± 3.1 mm in SL (P< 0.000). Post hoc findings were significant between VT and SIT (P< 0.000), and SL and SIT (P< 0.000). VT and SL LBP ratings both decreased, but not SIT. CONCLUSION Intermittent seated VT is a promising alternative for postural relief during seated computer work, producing SHC similar to lying down without compromising workflow.

Feasibility of a theory-based intervention to reduce sedentary behaviour among contact centre staff: the SUH stepped-wedge cluster RCT. PUBLIC HEALTH RESEARCH 2022.

Abstract
Background
Sedentary behaviour is linked to increased risk of type 2 diabetes, cardiovascular disease, musculoskeletal issues and poor mental well-being. Contact (call) centres are associated with higher levels of sedentary behaviour than other office-based workplaces. Stand Up for Health is an adaptive intervention designed to reduce sedentary behaviour in contact centres.
Objectives
The objectives were to test the acceptability and feasibility of implementing the intervention; to assess the feasibility of the study design and methods; to scope the feasibility of a future health economic evaluation; and to consider the impact of COVID-19 on the intervention. All sites received no intervention for between 3 and 12 months after the start of the study, as a waiting list control.
Design
This was a cluster-randomised stepped-wedge feasibility design.
Setting
The trial was set in 11 contact centres across the UK.
Participants
Eleven contact centres and staff.
Intervention
Stand Up for Health involved two workshops with staff in which staff developed activities for their context and culture. Activities ranged from using standing desks to individual goal-setting, group walks and changes to workplace policies and procedures.
Main outcome measures
The primary outcome was accelerometer-measured sedentary time. The secondary outcomes were subjectively measured sedentary time, overall sedentary behaviour, physical activity, productivity, mental well-being and musculoskeletal health.
Results
Stand Up for Health was implemented in 7 out of 11 centres and was acceptable, feasible and sustainable (objective 1). The COVID-19 pandemic affected the delivery of the intervention, involvement of contact centres, data collection and analysis. Organisational factors were deemed most important to the success of Stand Up for Health but also the most challenging to change. There were also difficulties with the stepped-wedge design, specifically maintaining contact centre interest (objective 2). Feasible methods for estimating cost-efficiency from an NHS and a Personal Social Services perspective were identified, assuming that alternative feasible effectiveness methodology can be applied. Detailed activity-based costing of direct intervention costs was achieved and, therefore, deemed feasible (objective 3). There was significantly more sedentary time spent in the workplace by the centres that received the intervention than those that did not (mean difference 84.06 minutes, 95% confidence interval 4.07 to 164.1 minutes). The other objective outcomes also tended to favour the control group.
Limitations
There were significant issues with the stepped-wedge design, including difficulties in maintaining centre interest and scheduling data collection. Collection of accelerometer data was not feasible during the pandemic.
Conclusions
Stand Up for Health is an adaptive, feasible and sustainable intervention. However, the stepped-wedge study design was not feasible. The effectiveness of Stand Up for Health was not demonstrated and clinically important reductions in sedentary behaviour may not be seen in a larger study. However, it may still be worthwhile conducting an effectiveness study of Stand Up for Health incorporating activities more relevant to hybrid workplaces.
Future work
Future work could include developing hybrid (office and/or home working) activities for Stand Up for Health; undertaking a larger effectiveness study and follow-up economic analysis (subject to its success); and exploring organisational features of contact centres that affect the implementation of interventions such as Stand Up for Health.
Trial registration
This trial is registered as ISRCTN11580369.

Abstract
ABSTRACT The increase in the use of technology for prolonged periods, both inside and outside of work, is associated with a sedentary lifestyle, a risk factor for several health problems. Change in this behavior can be promoted with the use of technologies. We aim to develop an interactive responsive website to promote behavioral changes in computer users. From a literature review, modifiable risk factors associated with health problems in computer users were identified. Messages were created to increase knowledge and promote behavioral changes in users. These messages include recommendations regarding breaks, adjustments in the workplace, physical exercise, hydration, among others. The messages are personalized, and the user includes personal information and current lifestyle habits. All this information was implemented in an interactive responsive website developed in JavaScript language and Node.js engine. The responsive website was developed, including the proposed features, and is available online. Future studies can evaluate the effectiveness of the responsive website in promoting behavioral changes among computer users, improving their health and quality of life.

Abstract
RESUMO O crescimento do uso da tecnologia fez com que os trabalhadores passassem a usar o computador por longos períodos, dentro e fora do trabalho. O uso prolongado de computadores está associado a um estilo de vida sedentário, sendo um fator de risco para diversos problemas de saúde. Porém, a transformação deste comportamento pode ser promovida por meio de tecnologias, como um site responsivo interativo que visa promover mudanças comportamentais em usuários de computador. A partir de um levantamento bibliográfico, foram identificados fatores de risco modificáveis associados aos problemas de saúde nessa população. Em seguida, foram criadas mensagens para ampliar o conhecimento e promover mudanças comportamentais nos usuários. Essas mensagens incluem recomendações a respeito de pausas, ajustes no posto de trabalho, exercícios físicos, hidratação, dentre outras. As mensagens podem ser personalizadas, bastando que, para isso, o usuário inclua informações pessoais e hábitos de vida atuais. Todas as informações foram implementadas em um site responsivo interativo desenvolvido em linguagem JavaScript e motor Node.js. O site responsivo foi desenvolvido, incluindo as funcionalidades propostas, e está disponível online. Em estudos futuros, poderá ser testada a efetividade do site para promover mudanças comportamentais nos usuários de computador, melhorando sua saúde e qualidade de vida.

Abstract
BACKGROUND There is strong evidence showing that sedentary behaviour time increase the risk to develop several chronic diseases and to premature death. The economic consequences of this risk have never been evaluated in France. The aim of this study was to estimate the economic burden of prolonged sedentary behaviour in France. METHODS Based on individual sedentary behaviour time, relative risk to develop cardiovascular disease, colon cancer, breast cancer and all-causes of premature mortality were identified. From relative risk and prevalence of sedentary behaviour time, a population attributable fraction approach was used to estimate the yearly number of cases for each disease. Data from the National Health Insurance were used to calculate the annual average costs per case for each disease. Disease-specific and total healthcare costs attributable to prolonged sedentary behaviour time were calculated. Indirect costs from productivity loss due to morbidity and premature mortality were estimated using a friction cost approach. RESULTS In France, 51 193 premature deaths/year appear related to a prolonged daily sedentary behaviour time. Each year prolonged sedentary behaviour cost 494 million € for the national health insurance. Yearly productivity loss due to premature mortality attributable to prolonged sedentary behaviour cost 507 million € and yearly productivity loss due to morbidity cost between 43 and 147 million €. CONCLUSION Significant saving and many deaths could be avoided by reducing prolonged sedentary behaviour prevalence in France. To address this issue, strong responses should be implemented to tackle sedentary behaviour, complementary to physical activity promotion.

Abstract
BACKGROUND Contact centre staff spend up to 95 % of their day seated, which can lead to a range of negative health outcomes. The aim of this study was to develop a programme theory for a complex intervention to reduce sedentary behaviour in contact centres. METHODS The 6SQuID model was used. A literature review, and focus groups at one contact centre were used to: understand the problem (step 1); identify modifiable factors (step 2); and develop a theory of change (step 3). A workshop shaped a theory of action (step 4), and the programme theory was refined after testing activities over 6 months (step 5). The intervention is currently undergoing further evaluation and feasibility testing in a larger scale stepped wedge randomised controlled study in 11 contact centres (Step 6). RESULTS Step 1: Limited opportunity to sit less, and move more at work was identified as the main problem. Step 2: Modifiable factors were identified at four levels of the centre. Step 3: A theory of change was developed around cultural norms and individual behaviour change. Step 4: Actions were developed to 'activate' the theory of change. Step 5: Activities were implemented, and adapted over 6 months and the programme theory was refined. CONCLUSION The programme theory behind this intervention is robust, evidence based, adaptive and transferable.

Abstract
Nowadays, the percentage of time that the population spends sitting has increased substantially due to the use of computers as the main tool for work or leisure and the increase in jobs with a high office workload. As a consequence, it is common to suffer musculoskeletal pain, mainly in the back, which can lead to both temporary and chronic damage. This pain is related to holding a posture during a prolonged period of sitting, usually in front of a computer. This work presents a IoT posture monitoring system while sitting. The system consists of a device equipped with Force Sensitive Resistors (FSR) that, placed on a chair seat, detects the points where the user exerts pressure when sitting. The system is complemented with a Machine Learning model based on Artificial Neural Networks, which was trained to recognize the neutral correct posture as well as the six most frequent postures that involve risk of damage to the locomotor system. In this study, data was collected from 12 participants for each of the seven positions considered, using the developed sensing device. Several neural network models were trained and evaluated in order to improve the classification effectiveness. Hold-Out technique was used to guide the training and evaluation process. The results achieved a mean accuracy of 81% by means of a model consisting of two hidden layers of 128 neurons each. These results demonstrate that is feasible to distinguish different sitting postures using few sensors allocated in the surface of a seat, which implies lower costs and less complexity of the system.

Abstract
Anthropometry is critical for product and workplace design. Highly prevalent, office work is associated with sedentarism and physical discomfort due to prolonged sitting. Dynamic seating (alternating across sitting, perching, and standing) has been suggested as an alternative to overcome those problems. The current study tested a large sample of anthropometric data for mismatch levels against national and international office furniture standards using dynamic seating as a framework with traditional and perching mismatch equations, applied to three recommended dynamic seating components. Dimensions present in the standards used did not match the majority of the sample. For sitting, seat width and depth individually presented the lowest levels of match, as well as under cumulative fit of all office furniture dimensions. However, these were alleviated when incorporating adjustability. Perching was shown to be generally impeded given commercially-available chair height options. Limitations in state-of-the-art perching equations are discussed, and two new models are proposed as design alternatives. Further research should focus on testing the criteria presented in this research through discomfort and objective measures.

Abstract
BACKGROUND Sedentary behaviour (SB) has been identified as an important mortality risk factor. Health organizations have recognised SB as a public health challenge with major health, social, and economic consequences. Researchers have alerted the need to develop specific strategies, to monitor, prevent, and reduce SB. However, there is no systematic analysis of the SB changes in European Union adults. We aimed to examine SB changes between 2002 and 2017 in the European Union (EU) adult population. METHODS SB prevalence (>4h30mins of sitting time/day) of 96,004 adults as a whole sample and country-by-country was analysed in 2002, 2005, 2013, and 2017 of the Sport and Physical Activity EU Special Eurobarometers' data. The SB question of a modified version of the International Physical Activity Questionnaire was considered. SB prevalence between countries and within years was analysed with a χ2 test, and SB between genders was analysed with the Z-Score test for two population proportions. RESULTS An association between the SB prevalence and the years was found (p < 0.001), with increases for the whole sample (2002: 49.3%, 48.5-50.0 95% confidence interval (CI); 2017: 54.5%, 53.9-55.0 95% CI) and men (2002: 51.2%, 50.0-52.4 95% CI; 2017: 55.8%, 55.0-56.7 95% CI) and women (2002: 47.6%, 46.6-48.7 95% CI; 2017: 53.4%, 52.6-54.1 95% CI) separately. The adjusted standardised residuals showed an increase in the observed prevalence versus the expected during 2013 and 2017 for the whole sample and women and during 2017 for men. For all years, differences were observed in the SB prevalence between countries for the whole sample, and men and women separately (p < 0.001). Besides, the SB prevalence was always higher in men versus women in the overall EU sample (p < 0.001). CONCLUSIONS SB prevalence increased between 2002 and 2017 for the EU as a whole and for both sexes separately. Additionally, differences in SB prevalence were observed for all years between EU countries in the whole sample and both sexes separately. Lastly, SB was consistently higher in men than women. These findings reveal a limited impact of current policies and interventions to tackle SB at the EU population level.

Abstract
The aim of this study was to investigate facilitating and hindering factors when implementing a physical activity (PA)-promoting program among office workers moving to a flex office, by conducting a process evaluation. Additionally, we evaluated self-reported and perceived PA behaviors. With a mixed methods design, analyses were based upon data from interviews with 70 employees and repeated questionnaires from 152 employees. The PA-promoting program was fully implemented and supported by management. There was a strong health promoting culture, encouraging PA in the organization already at the start of the study. The lecture and the office design were rated as the most motivating program components. The use of stairs, breaks during meetings and social acceptance for standing and walking at work increased. Employees described a strive for variation, and how managers, the office environment, productivity and ergonomic aspects influenced sedentary behavior (SB) and PA. The need for the PA-promoting program was questioned, and the timing of the program was debated. To conclude, a strong organizational health culture combined with a facilitating physical environment can create sustainable positive PA behaviors in office settings. A thorough understanding of organizational needs and a participatory process are needed to tailor organizational interventions to decrease SB.

Abstract
The relationships between sedentary lifestyle, sitting behaviour, and low back pain (LBP) remain controversial. In this study, we investigated the relationship between back pain and occupational sitting habits in 64 call-centre employees. A textile pressure mat was used to evaluate and parameterise sitting behaviour over a total of 400 h, while pain questionnaires evaluated acute and chronic LBP. Seventy-five percent of the participants reported some level of either chronic or acute back pain. Individuals with chronic LBP demonstrated a possible trend (t-test not significant) towards more static sitting behaviour compared to their pain-free counterparts. Furthermore, a greater association was found between sitting behaviour and chronic LBP than for acute pain/disability, which is plausibly due to a greater awareness of pain-free sitting positions in individuals with chronic pain compared to those affected by acute pain.

Sedentary and Physical Activity Behavior in "Blue-Collar" Workers: A Systematic Review of Accelerometer Studies. J Phys Act Health 2019; 16:1060-1069. [PMID: 31469366 DOI: 10.1123/jpah.2018-0607] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Revised: 07/10/2019] [Accepted: 07/14/2019] [Indexed: 11/18/2022]
Abstract
BACKGROUND This systematic review assessed evidence on the accelerometer-measured sedentary and physical activity (PA) behavior of nonoffice workers in "blue-collar" industries. METHODS The databases CINAHL, Embase, MEDLINE, PubMed, and Scopus were searched up to April 6, 2018. Eligibility criteria were accelerometer-measured sedentary, sitting, and/or PA behaviors in "blue-collar" workers (≥10 participants; agricultural, construction, cleaning, manufacturing, mining, postal, or transport industries). Data on participants' characteristics, study protocols, and measured behaviors during work and/or nonwork time were extracted. Methodologic quality was assessed using a 12-item checklist. RESULTS Twenty studies (representing 11 data sets), all from developed world economies, met inclusion criteria. The mean quality score for selected studies was 9.5 (SD 0.8) out of a maximum of 12. Data were analyzed using a range of analytical techniques (eg, accelerometer counts or pattern recognition algorithms). "Blue-collar" workers were more sedentary and less active during nonwork compared with work time (eg, sitting 5.7 vs 3.2 h/d; moderate to vigorous PA 0.5 vs 0.7 h/d). Drivers were the most sedentary (work time 5.1 h/d; nonwork time 8.2 h/d). CONCLUSIONS High levels of sedentary time and insufficient PA to offset risk are health issues for "blue-collar" workers. To better inform interventions, research groups need to adopt common measurement and reporting methodologies.

In-Depth Investigation into the Transient Humidity Response at the Body-Seat Interface on Initial Contact Using a Dual Temperature and Humidity Sensor. SENSORS 2019; 19:s19061471. [PMID: 30917555 PMCID: PMC6471173 DOI: 10.3390/s19061471] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Revised: 02/20/2019] [Accepted: 03/21/2019] [Indexed: 12/04/2022]
Abstract
Relative humidity (RH) at the body-seat interface is considered an important factor in both sitting comfort and generation of health concerns such as skin lesions. Technical difficulties appear to have limited research aimed at the detailed and simultaneous exploration of RH and temperature changes at the body-seat interface; using RH sensors without the capability to record temperature where RH is recorded. To explore the causes of a spike in RH consistently produced on first contact between body and seat surface, we report data from the first use of dual temperature and RH (HTU21D) sensors in this interface. Following evaluation of sensor performance, the effect of local thermal changes on RH was investigated. The expected strong negative correlation between temperature and RH (R2 = −0.94) supported the importance of considering both parameters when studying impact of sitting on skin health. The influence of sensor movement speed (higher velocity approach: 0.32 cm/s ± 0.01 cm/s; lower velocity approach: 0.17 cm/s ± 0.01 cm/s) into a static RH region associated with a higher local temperature were compared with data gathered by altering the rate of a person sitting. In all cases, the faster sitting down (or equivalent) generated larger RH outcomes: e.g., in human sitting 53.7% ± 3.3% RH (left mid-thigh), 56.4% ± 5.1% RH (right mid-thigh) and 53.2% ± 2.7% RH (Coccyx). Differences in size of RH change were seen across the measurement locations used to study the body-seat interface. The initial sitting contact induces a transient RH response (duration ≤ 40 s) that does not accurately reflect the microenvironment at the body-seat interface. It is likely that any movement during sitting would result in similar artefact formation. As a result, caution should be taken when investigating RH performance at any enclosed interface when the surfaces may have different temperatures and movement may occur.

Gallagher KM, Payne M, Daniels B, Caldwell AR, Ganio MS. Walking breaks can reduce prolonged standing induced low back pain. Hum Mov Sci 2019; 66:31-37. [PMID: 30913414 DOI: 10.1016/j.humov.2019.03.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Revised: 03/15/2019] [Accepted: 03/17/2019] [Indexed: 11/28/2022]
Abstract
Standing is commonly recommended to reduce sedentary behavior in the workplace; however, constrained prolonged standing has also been linked to musculoskeletal symptoms, such as low back pain (LBP). Light physical activity breaks, such as walking, may change lumbar spine posture enough to reduce LBP during standing. This study assessed the effectiveness of inserting 5-minute walking breaks every 25 min for reducing prolonged standing-induced LBP development. Nineteen participants completed two bouts of standing lasting 2 h - one with a 5-minute walking break every 25 min and one with no breaks. Pain measures were completed throughout the trial to categorize participants as pain developers (PDs) or non-pain developers (non-PDs). Lumbar region kinematics angle and range of motion were measured continuously. In standing, 58% (11/19) of participants were PDs, compared to just 26% when walking breaks were inserted. Seventy-three percent (8/11) were categorized as non-PDs with walking breaks. Median lumbar flexion increased during walking compared to standing. Lumbar region range of motion in the coronal and transverse planes also increased during walking. The intermittent lumbar flexion may help decrease LBP during prolonged standing. These results demonstrate that walking breaks may help promote lumbar movement and reduce prolonged standing-induced LBP.

Abstract
BACKGROUND Call agents spend ~ 90% of their working day seated, which may negatively impact health, productivity, and wellbeing. This study aimed to explore the acceptability and feasibility of a multi-component workplace intervention targeting increased activity and decreased prolonged sitting in the contact centre setting prior to a full-scale effectiveness trial. METHODS An 8-week non-randomised pre-post feasibility study was conducted. Using a mixed methods approach, focus groups and interviews were thematically analysed to explore the acceptability and feasibility of key study phases, and provide context to agents' process evaluation and survey responses. The multi-component intervention, conducted in a single call centre, included height-adjustable workstations, emails, education and training sessions, and support from team leaders and a workplace champion. RESULTS Six (of 20) team leaders were recruited, with 17 of 84 call agents (78% female, 39.3 ± 11.9 years) completing baseline assessments and 13 completing follow-up. High workload influenced recruitment. Call agents perceived assessments as acceptable, though strategies are needed to enhance fidelity. Education sessions, height-adjustable workstations and emails were perceived as the most effective components; however, height-adjustable hot-desks were not perceived as feasible in this setting. CONCLUSIONS This study has identified unique, pragmatic considerations for conducting a multi-level, multi-component PA and SB intervention and associated evaluation in highly sedentary call agents in the challenging contact centre setting. The intervention was largely perceived positively, with call agents and team leaders describing numerous perceived positive effects on behavioural, health and work-related outcomes. Findings will be of value to researchers attempting to intervene in contact centres and will be used by the current authors to design a subsequent trial.

A global systematic scoping review of studies analysing indicators, development, and content of national-level physical activity and sedentary behaviour policies. Int J Behav Nutr Phys Act 2018; 15:123. [PMID: 30486826 PMCID: PMC6263060 DOI: 10.1186/s12966-018-0742-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2018] [Accepted: 10/25/2018] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND National policy approaches to physical activity (PA) promotion and sedentary behaviour (SB) reduction are needed to address rising rates of non-communicable diseases. Understanding the policy process and impact through robust research and evaluation is crucial for facilitating successful reforms in national health policy. This scoping review, therefore, aimed to map the evidence on indicators, development, and content of national PA and/or SB policies globally. METHODS A systematic search of academic and grey literature was conducted through six bibliographic databases, Google, and websites of three large organisations for PA promotion. RESULTS Out of 24,872 screened documents, 203 publications from 163 studies were selected. The selected studies investigated PA/SB policies in 168 countries worldwide, and we provided summary results for each of the countries. Overall, 69, 29, and 2% of the analyses of national PA/SB policies were conducted for high-, middle-, and low-income countries, respectively. Twenty-two percent of the studies mentioned SB policies as part of their analysis, with only one study focusing solely on assessing SB policies. Operational definitions of policy were found in only 13% of publications. Only 15% of the studies used a conceptual or theoretical framework. A large variety of methods were used for data collection and analysis of PA/SB policy. CONCLUSIONS We found that PA policy research is much more developed than it was considered several years ago. Research around SB policies is still in its infancy, but it seems to have experienced some positive progress in the last few years. Three key issues were identified that should be addressed in further research: [i] there is a lack of PA/SB policy research in low- and middle-income countries, which is an important limitation of the current body of evidence; [ii] the definition of policy varied significantly across studies, and most studies did not rely on any theoretical framework, which may impede cross-study comparisons; and [iii] studies have used a variety of methods to analyse policy, which may also cause problems with comparability. Future PA/SB policy research should aim towards a clearer conceptualisation of policy, greater reliance on existing theoretical frameworks, and the use and further development of standardised methods for PA/SB policy analysis.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:E1484.

Abstract
Contact centre call agents are highly sedentary at work, which can negatively affect cardio-metabolic health. This qualitative cross-sectional study explored factors influencing call agents' workplace physical activity (PA) and sedentary behaviour (SB), and perspectives on strategies to help agents move more and sit less at work. Semi-structured interviews and focus groups with call agents (n = 20), team leaders (n = 11) and senior staff (n = 12) across four contact centres were guided by the socio-ecological model and analysed thematically. Agents offered insights into the impact of high occupational sitting and low PA on their physical and mental health, and factors influencing their motivation to move more and sit less at work. Team leaders, although pivotal in influencing behaviours, identified their own workload, and agents' requirement to meet targets, as factors influencing their ability to promote agents to move more and sit less at work. Further, senior team leaders offered a broad organisational perspective on influential factors, including business needs and the importance of return on investment from PA and SB interventions. Unique factors, including continuous monitoring of productivity metrics and personal time, a physical connection to their workstation, and low autonomy over their working practices, seemed to limit call agents' opportunity to move more and sit less at work. Proposed strategies included acknowledgement of PA and SB within policy and job roles, height-adjustable workstations, education and training sessions and greater interpersonal support. Additionally, measuring the impact of interventions was perceived to be key for developing a business case and enhancing organisational buy-in. Multi-level interventions embedded into current working practices appear important for the multiple stakeholders, while addressing concerns regarding productivity.

Abstract
OBJECTIVE Occupational sitting time in white-collar workers represents a prominent contributor to overall daily sitting time, which is associated with various health risks. Workplace interventions intending to reduce sitting time during work typically focus on replacing sitting with standing. The aim was to investigate and compare actual and desired proportions of time spent sitting, standing, walking, and doing physically demanding tasks at work reported by desk-based workers. Cross-sectional data were collected from German desk-based workers (n = 614; 53.3% men; 40.9 ± 13.5 years). All were interviewed about their self-reported actual and desired level of sitting, standing, walking and physically demanding tasks at work. RESULTS Desk-based workers reported to sit 73.0%, stand 10.2%, walk 12.9% and do physically demanding tasks 3.9% of their working hours. However, the individuals desire to sit, stand, walk and do physically demand tasks significantly different [53.8% sit, 15.8% stand, 22.8% walk, physically demanding tasks (7.7%), p < 0.001]. The present data revealed greatest mismatch between the desk-based workers' actual and desired time for sitting and walking. Health promotion programs should offer not only options for more standing but also opportunities for more walking within the workplace setting to better match workers' desires.
