Indoor Tracking to Understand Physical Activity and Sedentary Behaviour: Exploratory Study in UK Office Buildings.

ABSTRACT: Little is known of the patterns of physical activity, standing and sitting by office workers. However, insight into these behaviours is of growing interest, notably in regard to public health priorities to reduce non-communicable disease risk factors associated with high levels of sitting time and low levels of physical activity. With the advent and increasing availability of indoor tracking systems it is now becoming possible to build detailed pictures of the usage of indoor spaces. This paper reports initial results of indoor tracking used in conjunction with the ActivPAL activity monitoring device. In this paper we give an overview of the usage of the tracking system and its installation and illustrate some of the resultant data. We also provide preliminary results that investigate the relationship between location, light physical activity and sitting in a small sample of office workers (n=33) from two separate office environments in order to demonstrate the relevance and explanatory power of the technique.

Project description:BackgroundOffice workers spend a significant part of their workday sitting. Interventions that aim to reduce sedentary behaviour and increase physical activity might be more effective if greater attention is paid to individual perspectives that influence behavioural choices, including beliefs and values. This study aimed to gain insight into office workers' perspectives on physical activity and sedentary behaviour.MethodsSixteen Dutch office workers (50% female) from different professions participated in semi-structured face-to-face interviews in March 2019. To facilitate the interviews, participants received a sensitizing booklet one week before the interview. The booklet aimed to trigger them to reflect on their physical activity and sedentary behaviour and on their values in life. All interviews were audiotaped, transcribed verbatim and coded following codebook thematic analysis.ResultsSix themes were identified: 1) beliefs about health effects are specific regarding physical activity, but superficial regarding sedentary behaviour; 2) in addition to 'health' as a value, other values are also given priority; 3) motivations to engage in physical activity mainly stem from prioritizing the value 'health', reflected by a desire to both achieve positive short/mid-term outcomes and to prevent long-term negative outcomes; 4) attitudes towards physical inactivity and sedentary behaviour are diverse and depend on individual values and previous experiences; 5) perceived barriers depend on internal and external factors; 6) supporting factors are related to support and information in the social and physical environment.ConclusionsThe great value that office workers attach to health is reflected in their motivations and attitudes regarding physical activity. Increasing office workers' knowledge of the health risks of prolonged sitting may therefore increase their motivation to sit less. Although 'health' is considered important, other values, including social and work-related values, are sometimes prioritized. We conclude that interventions that aim to reduce sedentary behaviour and increase physical activity among office workers could be improved by informing about health effects of sedentary behaviour and short/mid-term benefits of physical activity, including mental health benefits. Moreover, interventions could frame physical activity as congruent with values and support value-congruent choices. Finally, the work environment could support physical activity and interruption of sedentary behaviour.

Project description:BackgroundThe COVID-19 pandemic has affected the physical behaviours of office workers worldwide, but studies comparing physical behaviours between countries with similar restrictions policies are rare. This study aimed to document and compare the 24-hour time-use compositions of physical behaviours among Brazilian and Swedish office workers on working and non-working days during the pandemic.MethodsPhysical behaviours were monitored over 7 days using thigh-worn accelerometers in 73 Brazilian and 202 Swedish workers. Daily time-use compositions were exhaustively described in terms of sedentary behaviour (SED) in short (< 30 min) and long (≥30 min) bouts, light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and time-in-bed. We examined differences between countries using MANOVA on data processed according to compositional data analysis. As Swedish workers had the possibility to do hybrid work, we conducted a set of sensitivity analyses including only data from days when Swedish workers worked from home.ResultsDuring working days, Brazilian office workers spent more time SED in short (294 min) and long (478 min) bouts and less time in LPA (156 min) and MVPA (50 min) than Swedish workers (274, 367, 256 and 85 min, respectively). Time spent in bed was similar in both groups. Similar differences between Brazilians and Swedes were observed on non-working days, while workers were, in general, less sedentary, more active and spent more time-in-bed than during working days. The MANOVA showed that Brazilians and Swedes differed significantly in behaviours during working (p < 0.001, ηp2 = 0.36) and non-working days (p < 0.001, ηp2 = 0.20). Brazilian workers spent significantly more time in SED relative to being active, less time in short relative to long bouts in SED, and more time in LPA relative to MVPA, both during workdays and non-workdays. Sensitivity analyses only on data from days when participants worked from home showed similar results.ConclusionsDuring the COVID-19 pandemic Brazilian office workers were more sedentary and less active than Swedish workers, both during working and non-working days. Whether this relates to the perception or interpretation of restrictions being different or to differences present even before the pandemic is not clear, and we encourage further research to resolve this important issue.

Project description:BackgroundInterventions to increase physical activity or reduce sedentary behaviour within the workplace setting have shown mixed effects. This cluster randomised controlled trial assessed whether multi-component interventions, focusing on changes at the individual, environmental, and organisational levels, either increased physical activity or reduced sedentary behaviour, compared to a passive control group.MethodsTeams of office-workers from two companies participated in one of two interventions (iPA: targeting physical activity; or iSED: targeting sedentary behaviour), or wait-list control group (C). Exclusion criterion was very high physical activity level (MVPA ≥30 min/day in ≥10 min bouts every day). Randomisation occurred at the level of workplace cluster, and groups were randomly allocated (1:1) with stratification for company and cluster size. Personnel involved in data collection and processing were blinded to group allocation. Both interventions included five sessions of cognitive behavioural therapy counselling for 6 months. iPA included counselling focused on physical activity, access to a gym, and encouragement to exercise, and go for lunch walks. iSED included counselling on sedentary behaviour and encouragement to reduce sitting and increase engagement in standing- and walking-meetings. At baseline and the 6-month mark accelerometers were worn on the hip and thigh for 7 days. The primary outcomes were group differences in time spent in moderate-to-vigorous intensity physical activity (%MVPA) and in sedentary behaviour (%), analysed using Bayesian multilevel modelling for those with complete data.ResultsTwo-hundred and sixty three office workers (73% women, mean age 42 ± 9 years, education 15 ± 2 years) were randomised into 23 cluster teams (iPA n = 84, 8 clusters; iSED n = 87, 7 clusters; C n = 92, 7 clusters). No significant group differences (posterior mean ratios: 95% credible interval) were found after the intervention for %MVPA or for %Sedentary. %MVPA: iPA vs C (0·04: - 0·80-0·82); iSED vs C (0·47: - 0·41-1·32); iPA vs iSED (0·43: - 0·42-1·27). %Sedentary: iPA vs C (1·16: - 1·66-4·02); iSED vs C (- 0·44: - 3·50-2·64); iPA vs iSED (- 1·60: - 4·72-1·47).ConclusionsThe multi-component interventions focusing on either physical activity or sedentary behaviour were unsuccessful at increasing device-measured physical activity or reducing sedentary behaviour compared to a control group.Trial registrationISRCTN, ISRCTN92968402 .
