Before we start…

Please feel free to stand, and move and sit and stand and sit etc…

Too much sitting is bad for our health

http://sitlessmovemore.ca

Why all this interest in sitting?

It has personal relevance

Everyone sits Everyone has a sitting story … I get aches and pains when I sit too long (83 yr old women) … In my new job I am run off my feet – I’ve lost 8kg (51 yr old women) … Going back to work after paternity leave – sitting all day – I

felt so achy and flat (40 yr old man)

The landscape has changed

45 ± 14 kcal/day

27 ± 9 kcal/day

80 ± 28 kcal/day

54 ± 19 kcal/day

Not just about total sitting time

• More breaks associated with lower waist circumference1

Experimental evidence • Interrupting prolonged sitting associated with better

postprandial glucose & insulin response2

• One hour of exercise does not offset the negative effects on inactivity on insulin & lipids if the rest of the day is spent sitting3

Interventions

“The results suggest that simple interventions that can be implemented in the workplace and domestically to decrease passive sitting time and increase the number of breaks can also lead to substantial health improvements.”

“Workplaces are best placed to provide the supportive cultures often needed to sustain lifestyle change”

1. Understanding the problem

Thorp et al., IJBNPA, 2012

1. Understanding the problem

• Office workers spend a lot of work time sitting • A lot of this sitting time is unbroken (30mins+)

Thorp et al., IJBNPA, 2012

Proportion of prolonged (≥30 mins) sedentary time (%) at work

55.5% 21.5%

Sitting <30mins Sitting 30mins+

2. Review of previous strategies

5 key approaches (2010) 1. Increasing the number of breaks

from sitting 2. Postural changes 3. Ergonomic changes to individual

workspace 4. Altering the built design of the

broader workplace 5. Multiple strategies

Timeline of events • Oct: Ergotron offered a single trial sit-stand workstation

• Dec: CPRC purchased sit-stand workstations

• Jan – April: controlled clinical trial evaluating impact of workstation installation (Stand Up CPRC)1

• May – protocol of large trial modified to include workstations

• July – Sep: Pilot (Stand Up Comcare)2 + other formative research

• Jan – Jan 2013: WS vs. multicomponent (Stand Up UQ)3

• March: Recruitment for large trial begins (Stand Up Victoria)

• Oct 2013: Baseline recruitment for Stand Up Vic to be completed

Key message

Stand Up, Sit Less, Move More Aiming to: • Reduce total workplace sitting time (Sit Less) • Reduce the number of sitting bouts (Sit Less) • Reduce the length of the sitting bouts (Stand Up)

– particularly those 30mins+ • Increase standing and moving time (Move More) • Make changes throughout the day

• both in and out of the workplace

Achieve this via environmental & organizational & individual strategies

Stand Up Australia

Organizational strategies

1. Senior management consultation (~30-45mins) • Background & rationale • Identification of relevant OHS policies & organizational

structures, team champions & any additional resources

2. Representatives consultation workshop (~2-4hrs) • Participatory approach: reps from various levels • Identification of organizational-appropriate strategies to

support key message “Stand Up, Sit Less, Move More” • Manager emails, champion for change

• Installing workstations for all employees

Next question…

How much did the organisational & individual elements add to the change?

Qualitative feedback: participants

… just having the option to sit or stand was great … everyone now more aware of sitting/standing; everyone

still walking to colleagues to talk; there is more standing in meetings (when prompted) [Multicomponent participant]

…. The manager emails were very useful, bringing everyone

onto the same page and encourage to try things (tips of the week), reinforcing support; thinks if [manager] did that again it would help her group to get into better habits again [Multicomponent participant]

.

Stand Up UQ: since the research study

Study groups • Workstation only group purchased workstations • Multicomponent: looking to refurbish

UQ wide • Working with OHS: prolonged sitting as part of risk

assessment training • Enabling height adjustable desks to be an option as

part of a refurbishment / replacement • Gradual dissemination of practice

Enabling height adjustable desks to be an option as

Summary of finding (so far…)

Changing the individual physical environment …. but need support Key support elements • Information • Participatory approach • Champions for change • Visible support (e.g. signs, emails) • Individual coaching

Easy to start the change

• Become a champion • Online materials

• Juststand.org • Sedentary work practices toolkit (Comcare)

• Post signs • “This is a stand friendly workplace” • “We support standing meetings” • “Stand up for your health”

• Walking office tracks

Evaluate the impact make the business case for change

• Partner with research • Existing measures

• Absenteeism, productivity, engagement surveys • Technology

• Social media
