Influence of short bouts of stair climbing on young adults during prolonged sitting on posture, discomfort, and musculoskeletal performance outcomes: a counterbalanced pilot randomised crossover trial.

Prolonged sitting is postulated to influence musculoskeletal performance (cervical flexor endurance, balance, and agility), discomfort and alter cervical spine angles during work-based computer use. Stair climbing breaks may be a great addition at typical and home offices however remain unexplored for its impact on musculoskeletal performance. In our counterbalanced pilot crossover trial, 24 adults were randomised to three interventions: (1) prolonged sitting, (2) interrupted by 2 min of self-paced, and (3) externally paced stair climbing for 2 h. Cervical spine angles were measured every 30 min while balance, agility, endurance, and discomfort were assessed before and after 120 min. Stair climbing interruptions have favourable effects on agility (F = 8.12, p = 0.009, ηp2 = 0.26) and musculoskeletal discomfort, but failed to improve other musculoskeletal outcomes associated with prolonged sitting. Brief stair climbing interruptions are effective in improving discomfort and agility while pragmatic trials are warranted for translated effects.

Stair climbing interventions are known for their cardiovascular benefits, however their impact on musculoskeletal performance remains unclear. In our randomised crossover pilot study, we explored the effects of stair climbing interruptions on cervical posture, endurance, agility, and balance during 120 min of prolonged sitting. Stair climbing interruptions were favourable in reducing time to complete agility tasks and neck/shoulder discomfort score compared to prolonged sitting. However other performance measures remained unaltered.

Breaking the Habit? Identifying Discrete Dimensions of Sitting Automaticity and Their Responsiveness to a Sitting-Reduction Intervention.

BACKGROUND: Growing evidence suggests that sitting is activated automatically on exposure to associated environments, yet no study has yet sought to identify in what ways sitting may be automatic. METHOD: This study used data from a 12-month sitting-reduction intervention trial to explore discrete dimensions of sitting automaticity, and how these dimensions may be affected by an intervention. One hundred ninety-four office workers reported sitting automaticity at baseline, and 3 months, 6 months, 9 months and 12 months after receiving one of two sitting-reduction intervention variants. RESULTS: Principal component analysis extracted two automaticity components, corresponding to a lack of awareness and a lack of control. Scores on both automaticity scales decreased over time post-intervention, indicating that sitting became more mindful, though lack of awareness scores were consistently higher than lack of control scores. CONCLUSION: Attempts to break office workers' sitting habits should seek to enhance conscious awareness of alternatives to sitting and afford office workers a greater sense of control over whether they sit or stand.

Self-reported behaviour change among multiple sclerosis community members and interested laypeople 6 months following participation in a free online course about multiple sclerosis.

ISSUE ADDRESSED: Evaluated the impact of the Understanding Multiple Sclerosis (MS) massive open online course, which was intended to increase understanding and awareness about MS, on self-reported health behaviour change 6 months after course completion. METHODS: Observational cohort study evaluating precourse(baseline) and postcourse (immediately postcourse and six-month follow-up) survey data. The main study outcomes were self-reported health behaviour change; change type; and measurable improvement. We also collected participant characteristic data (eg, age, physical activity). We compared participants who reported health behaviour change at follow-up to those who did not and compared those who improved to those who did not using χ2 and t tests. Participant characteristics, change types and change improvement were described descriptively. Consistency between changes reported immediately postcourse and at the 6-month follow-up was assessed using χ2 tests and textual analysis. RESULTS: N = 303 course completers were included in this study. The study cohort included MS community members (eg, people with MS, healthcare providers) and nonmembers. N = 127 (41.9%) reported behaviour change in ≥1 area at follow-up. Of these, 90 (70.9%) reported a measured change, and of these, 57 (63.3%) showed improvement. The most reported change types were knowledge, exercise/physical activity and diet. N = 81 (63.8% of those reporting a change) reported a change in both immediately and 6 months after course completion, with 72.0% of those that described both changes giving similar responses each time. CONCLUSION: Understanding MS encourages health behaviour change among course completers up to 6 months after course completion. SO WHAT?: An online education intervention can effectively encourage health behaviour change over a 6-month follow-up period, suggesting a transition from acute change to maintenance. The primary mechanisms underpinning this effect are information provision, including both scientific evidence and lived experience, and goal-setting activities and discussions.

Supporting engagement and retention of online and blended-learning students: A qualitative study from an Australian University.

Enrolment numbers in online higher education courses have continued to increase over the last decade. The challenges brought about by the COVID-19 pandemic have further accelerated the growth in online and blended course offerings. The development of institutional support services, however, does not reflect this growth. Many students are not equipped with the skills or given adequate support to engage and succeed in their courses, leading to student disengagement and attrition. This study investigated the perceptions of students in online and blended subjects, regarding both the academic and institutional support they were provided. The research team collected interview data from 41 online and blended-learning students and then analysed these data using an iterative thematic analysis approach. This article introduces the key findings with two models: one presenting support strategies at multiple levels within this university; the other presenting three key elements of subject-level teacher support, which were identified by the interviewees as the most significant, effective, and relevant support mechanism in this context. The findings will inform higher education institutions who aim to engage and support online and blended students better, through an improved understanding of how support is perceived by this student cohort. This study was conducted at one Australian university; however, the findings are relevant to higher education institutions in other countries that strive to bring about positive experiences and enhance retention rates for online and blended students.

Peer champions responses to nudge-based strategies designed to reduce prolonged sitting behaviour: Lessons learnt and implications from lived experiences of non-compliant participants.

Occupational sedentariness is problematic for office-based workers because of their prolonged sitting periods and the advent of technology which reduces work-based movement. A common workplace strategy to deal with this preventable health risk is to have workers engage in brief movement breaks throughout the workday. To date, the use of interventions underpinned by individual self-regulation has had less than optimal impact on changing workers sedentary work behaviours. An alternative design for workplace interventions is the use of nudge theory. Nudge theory incorporates strategies that are delivered at the point of choice designed to influence individual decision making regarding alternative behaviour options. In this study, desk-based workers were exposed to two nudge strategies which suggested alternative behaviours of regular standing and taking movement breaks during work periods to the default behaviours of prolonged sitting and sedentary work behaviour. A small group of women managers who served as peer champions (n = 6), withdrew early from the study, and then took part in an exit interview to gain an understanding of their experiences of being exposed to the two nudge strategies. Verbatim transcripts were analysed using inductive, reflexive thematic analysis. Two major themes with seven second order themes central to their experiences were extracted: facilitative behaviour and feelings (advocacy, acceptance & facilitative burden) and dysfunctional behaviours and feelings (dysfunctional behaviour & feelings, control, reactance & presenteeism). Participants initially perceived a positive exchange associated with exposure to nudge strategies. Yet, participants' emotional connection to their work roles and behaviour were perceived as a negative exchange. Participants cited numerous maladaptive feelings because of a perception of incongruency with the established work normative behaviour. These findings reveal that nudge strategies of reduced choice and social norms are viable, but perceptions of monitoring can moderate adherence.

An exploratory study regarding communication facilitators and barriers reported by a cohort of multiple sclerosis (MS) community members from the international massive open online course 'Understanding MS'.

BACKGROUND: Effective communication is essential for high-quality multiple sclerosis (MS)-related healthcare, but significant knowledge and practice gaps remain in this area. The aim of this study was to explore facilitators and barriers of communication about MS reported by members of the MS community. METHODS: We conducted an exploratory mixed method study analysing self-reported facilitators and barriers to communication among MS community members participating in a free international online course about MS (called Understanding MS) who commented on an optional discussion board. We quantitatively compared commenters with course participants who did not comment and, among commenters, compared health information consumers (people with MS, caregivers) and suppliers (healthcare providers, service providers, researchers) using chi square and t-tests. We evaluated free text discussion board responses for emergent themes, comparing and contrasting consumer and supplier responses. RESULTS: We found that the sociodemographic characteristics of commenters (n = 262) were similar to course participants overall including age, sex and MS community role. However, among commenters, consumers (n = 152) were about 9 years older than suppliers (n = 57) on average (mean age consumers 52.9 years; suppliers 44.0 years p<0.001), and were less likely to have a university degree (p = 0.004) or live in Australia (the course host country representing almost 60% of the cohort; p<0.001). Nonetheless, consumers and suppliers listed similar facilitators for communication about MS: honesty, kindness/empathy/compassion, openness, and effective listening. Consumers further prioritized clarity and patience. Consumers were also more likely to list barriers to communication, commonly listing the following barriers: encountering a lack of knowledge about MS, the invisible symptoms of MS, uncertainty about the appropriate amount of communication, and concern about being perceived as complaining and/or burdening others. Finally, consumers also discussed communication as a means to educate others about MS. CONCLUSIONS: Effective communication remains a challenge in the MS community, particularly between health information suppliers and health information consumers. The results of this exploratory study highlight areas that should be considered when developing communication strategies for MS community members. A larger confirmatory study of MS health information consumers and suppliers that uses focus groups and individual interviews could be conducted to further explore these emerging themes.

Self-reported behaviour change among multiple sclerosis community members and interested laypeople following participation in a free online course about multiple sclerosis.

ISSUE ADDRESSED: Evaluated the impact of Understanding Multiple Sclerosis (MS) massive open online course, which was intended to increase understanding and awareness about MS, on self-reported health behaviour change. METHODS: Observational cohort study evaluating pre- (baseline) and post-course (8-10-week follow-up) survey data. The main study outcomes were self-reported health behaviour change, change type and measurable improvement. We also collected participant characteristic data (eg, age, physical activity). We compared participants who reported health behaviour change at follow-up to those who did not and compared those who improved with those who did not using chi square and t tests. Participant characteristics, change types and change improvement were described descriptively. RESULTS: A total of N = 560 course completers were included in this study. The study cohort included MS community members (eg, people with MS, health care providers) and nonmembers. Two hundred and forty-seven (44.1%) reported behaviour change in ≥1 area at follow-up, 160 (64.8%) reported a measurable change and, of these, 109 (68.1%) showed improvement. Participants who reported a change and those who improved had significantly lower precourse health behaviours and characteristics (eg, quality of life, diet quality). The most reported change types were knowledge, exercise/physical activity, diet and care practice. CONCLUSION: Understanding MS encourages health behaviour change among course completers, primarily through the provision of information and goal-setting activities and discussions. SO WHAT?: An online education intervention can effectively encourage health behaviour change over an 8-10-week follow-up period. Information provision, including both scientific evidence and lived experience, and goal-setting activities and discussions are the primary mechanisms underpinning that change.

The curriculum took a back seat to huff and puff: Teaching high school health and physical education during Covid-19.

This study examined secondary (high) school teachers' experiences of online delivery of health and physical education (HPE) during Covid-19 suppression measures in one Australian state in 2020. Research has noted the use of blended learning and flipped classrooms in HPE, yet little is known about the delivery of fully online school HPE. Semi-structured interviews occurred with eight high school HPE specialist teachers, providing qualitative data for analysis. The analysis of teachers' experiences indicated that in most cases HPE did not happen; rather, physical activity provision was initiated, or HPE was marginalised to a movement break between subjects with perceived higher status and priority. Additionally, teachers found that providing HPE online was challenging, and struggled to connect with, engage and provide equitable opportunities for their students online. The results showed that the move to online provision of HPE resulted in diminished educative purpose.

Taking a Stand for Office-Based Workers' Mental Health: The Return of the Microbreak.

There is evidence that movement-based microbreaks can improve the cardiovascular health of desk-based employees, but their effect on mood states is yet to be investigated. As daily work tasks can potentially result in the loss of physical and psychological resources, the objective of this study was to measure the effect of movement microbreaks during formal work time on mood states. In a randomized-controlled pilot study with repeated measures (baseline, post-test, washout) of self-reported job stress and mood states (fatigue and vigor), police officers (N = 43) were exposed to movement microbreaks during work hours. A multivariate significant difference between groups was noted after the intervention period. Further analysis revealed that the experimental group reported a latent reduction in job-related stress after the 3-months washout period. Although the study was conducted with a small sample, our preliminary findings suggest that interrupting sedentary work with movement microbreaks may have beneficial effects on employee mental health. The implications of movement microbreaks for mitigating work-related stress of first responders, including police, is discussed, along with directives for future research.

How Did Parents View the Impact of the Curriculum-Based HealthLit4Kids Program Beyond the Classroom?

The HealthLit4Kids program aims to build health literacy in a participatory and contextually relevant way. Whole-of-school and curriculum strategies aim to empower and build capacity to make informed health choices amongst students, teachers, parents, and their local community. The aim of this study was to evaluate the HealthLit4Kids program from the perspective of parents, using a Self-Determination Theory framework. This is one component within a larger evaluation of the program. Parents at four Australian primary schools were interviewed post-program. Qualitative data collected through parent interviews were analyzed thematically to identify themes, and coding checks were completed by experienced qualitative researchers. The three key themes identified were student engagement, behaviour change, and parent engagement. Findings also indicated that parents placed a high value on effective communication from schools and raised a range of health areas such as food and nutrition, physical activity, and mental health with the interviewer. Parent opinions of the HealthLit4Kids program were positive, with many reporting a perceived increase in their children's ability to understand, communicate and act on health-related knowledge at home. The HealthLit4Kids program requires further research to determine its viability as an optimal pedagogical strategy for the health literacy development of primary school-aged children.

Blood Pressure Response to Interrupting Workplace Sitting Time With Non-Exercise Physical Activity: Results of a 12-Month Cohort Study.

OBJECTIVE: To evaluate the blood pressure (BP) effects of a yearlong e-health solution designed to interrupt prolonged occupational sitting time. METHODS: BP data of 228 desk-based employees (45.1 ±â€Š10.5 years) were analyzed at baseline, 3, 6, 9, and 12 months. RESULTS: Systolic BP significantly reduced from baseline for the first 9 months (1.0 to 3.4 mmHg; P < 0.01) while diastolic and mean arterial pressure decreased for the full 12-months (4 to 5 mmHg for diastolic pressure and 3.6 to 4.2 mmHg for MAP; all P < 0.01).Participants used the e-health solution 5.5 ±â€Š2.0 times/day in the first 3 months which reduced to 4.2 ±â€Š2.5 times/day by the end of the study (P < 0.05). CONCLUSIONS: An e-health solution designed to increase non-exercise physical activity by interrupting sitting time in the workplace is feasible and produced long-term reductions in blood pressure.

Is self-reporting workplace activity worthwhile? Validity and reliability of occupational sitting and physical activity questionnaire in desk-based workers.

BACKGROUND: With the advent of workplace health and wellbeing programs designed to address prolonged occupational sitting, tools to measure behaviour change within this environment should derive from empirical evidence. In this study we measured aspects of validity and reliability for the Occupational Sitting and Physical Activity Questionnaire that asks employees to recount the percentage of work time they spend in the seated, standing, and walking postures during a typical workday. METHODS: Three separate cohort samples (N = 236) were drawn from a population of government desk-based employees across several departmental agencies. These volunteers were part of a larger state-wide intervention study. Workplace sitting and physical activity behaviour was measured both subjectively against the International Physical Activity Questionnaire, and objectively against ActivPal accelerometers before the intervention began. Criterion validity and concurrent validity for each of the three posture categories were assessed using Spearman's rank correlation coefficients, and a bias comparison with 95 % limits of agreement. Test-retest reliability of the survey was reported with intraclass correlation coefficients. RESULTS: Criterion validity for this survey was strong for sitting and standing estimates, but weak for walking. Participants significantly overestimated the amount of walking they did at work. Concurrent validity was moderate for sitting and standing, but low for walking. Test-retest reliability of this survey proved to be questionable for our sample. CONCLUSIONS: Based on our findings we must caution occupational health and safety professionals about the use of employee self-report data to estimate workplace physical activity. While the survey produced accurate measurements for time spent sitting at work it was more difficult for employees to estimate their workplace physical activity.

Activity Behaviors of University Staff in the Workplace: A Pilot Study.

BACKGROUND: Sedentary behavior is related to metabolic syndrome and might have implications for the long-term health of workers in a low activity environment. The primary aim of this pilot study was to determine activity levels of adults working at a University during work hours. A secondary aim was to determine the relationship between actual and perceived activity levels. METHODS: Activity levels of university staff (n = 15, male = 7, age = 53 ± 7 years, BMI = 26.5 ± 2.5kg·m2) were monitored over 5 consecutive workdays using SenseWear accelerometers, then participants completed a questionnaire of their perception of workplace sedentary time. RESULTS: Each participant spent 71.5 ± 13.1% (358 ± 78 min) of their workday being sedentary (< 1.5 METs), 15.6 ± 9.0% involved in light activity (1.5-3 METs), 11.7 ± 10.0% in moderate activity (3-5 METs), and 1.1 ± 1.3% in vigorous activity (> 5 METs) (P < .0001). The mean difference between actual (SenseWear < 1.5 METs) and perceived sitting time was -2 ± 32%; however, perceived sedentary time was reported with a range of under-to-over estimation of -75% to 51%. CONCLUSION: This pilot study identifies long periods of low metabolic activity during the workday and poor perception of individual sedentary time. Interventions to reduce sedentary time in the workplace may be necessary to ensure that the work environment does not adversely affect long-term health.

The effect of an e-health intervention designed to reduce prolonged occupational sitting on mean arterial pressure.

OBJECTIVE: To evaluate the effect of a workplace health intervention designed to reduce prolonged occupational sitting on the mean arterial pressure (MAP) of desk-based employees. METHODS: This randomized controlled trial involved an experimental group who received an e-health intervention and a control group who did not. The 13-week intervention passively prompted participants to stand and engage in short bouts of office-based physical activity by interrupting prolonged occupational sitting time periodically throughout the workday. Mean arterial pressure was measured at pretest and posttest. RESULTS: Between pretest and posttest the experimental group significantly reduced their MAP, whereas MAP in the control group did not. CONCLUSIONS: A workplace e-health intervention designed to reduce prolonged occupational sitting was effective in decreasing MAP in desk-based employees.

Assessment of the impact of a workplace intervention to reduce prolonged occupational sitting time.

We aim to provide a better picture of the outcomes associated with implementing a nonpurposeful, physical activity, e-health intervention in a professional workplace. There is a need for health professionals to evaluate physical-activity-based workplace health interventions with a full range of measures. Using a social ecological model as a basis, we identify a range of subjective outcomes from 15 interviews of a cross section of participants. We document that not only did participants report a range of positive outcomes across multiple systems of influence, but they experienced some negative outcomes because of disruption to work flow and a changing of work habit. We conclude that using subjective evaluations provides a comprehensive picture of the factors that influence judgments of the efficacy of a workplace health intervention.

An e-health intervention designed to increase workday energy expenditure by reducing prolonged occupational sitting habits.

BACKGROUND: Desk-based employees face multiple workplace health hazards such as insufficient physical activity and prolonged sitting. OBJECTIVE: The objective of this study was to increase workday energy expenditure by interrupting prolonged occupational sitting time and introducing short-bursts of physical activity to employees' daily work habits. METHODS: Over a 13-week period participants (n=17) in the intervention group were regularly exposed to a passive prompt delivered through their desktop computer that required them to stand up and engage in a short-burst of physical activity, while the control group (n=17) was not exposed to this intervention. Instead, the control group continued with their normal work routine. All participants completed a pre- and post- intervention survey to estimate workplace daily energy expenditure (calories). RESULTS: There was a significant 2 (Group) × 2 (Test) interaction, F (1, 32)=9.26, p < 0.05. The intervention group increased the calories expended during the workday from pre-test (M=866.29 ± 151.40) to post-test (M=1054.10 ± 393.24), whereas the control group decreased calories expended during the workday from pre-test (M=982.55 ± 315.66) to post-test (M=892.21 ± 255.36). CONCLUSIONS: An e-health intervention using a passive prompt was an effective mechanism for increasing employee work-related energy expenditure. Engaging employees in regular short-bursts of physical activity during the workday resulted in reduced sitting time, which may have long-term effects on the improvement of employee health.
