New Australian body size data study predicts 3kg weight gain every 10 years – we need to design for it

 

iMOVE Cooperative Research Centre

Australia’s first anthropometry dataset has revealed we are stacking on about 3kg every ten years – with big implications for transport design, including how big airline seats should be.

Anthropometry is the study of measuring human body sizes and shapes.

The ground-breaking study conducted by academics at the University of South Australia for partners Transport for NSW (TfNSW) and Department of Transport and Planning Victoria and funded by the iMOVE Cooperative Research Centre has produced a comprehensive anthropometric dataset for Australian adults aged 18-64 – the first time this has been done for the Australian population.

In developed countries, obesity and weight gain have risen among adults since the 1960s and children since the 1980s. For Australia, the new dataset suggests a continuing increase in weight for adults of between 1.5 and 3.5kg per decade.

“Overall, a likely scenario for Australia over the next 20 years is: no increase in stature, and a 2 to 3kg increase in weight per decade. A conservative scenario, which would lead to more accommodating designs, is an increase in stature of 10mm per decade, and an increase in weight of 3kg weight gain per decade,” the university researchers said in their final report released this week.

The researchers noted the relationship between bigger body sizes and airline seats, citing studies that found “changes in body shape dimensions over the past 30 years have rendered airline seating dimensions to be problematic, and unable to accommodate up to 68% of males and 22% of females”.

Historically, commercial airline seating was based on average passenger weight data from the 1950s to 1970s. But as the modern traveller becomes significantly heavier, airlines are facing challenges in accommodating an increasingly larger passenger base.

The weight gain trend has serious implications for aircraft design and fuel efficiency. Heavier planes require more fuel, which in turn drives up operational costs and environmental concerns. The issue has gathered significant media interest in recent weeks with US financial analysts saying United Airlines would save USD $80m a year if the average passenger lost about 4.5kg.

What about trains, buses, and other forms of transport?

The researchers said the new dataset can help industry deal with these issues. “Anticipating the changes in body size over decades is important if one wants to ensure that a design, equipment, or layout will remain fit for use by the intended users over its entire life span,” they said.

Ian Christensen, Managing Director of iMOVE CRC, commented on the study’s findings: 

“This research is not just about numbers on a scale. It’s about understanding the evolving needs of our population and ensuring our transport systems, both on the ground and in the air, are equipped to serve everyone comfortably and safely with human-centred design.

“The data from this study provides a roadmap for the future. It’s an opportunity for designers, policymakers, and industry leaders to come together and create transport solutions that are inclusive, sustainable, and forward-thinking.”

Christina Kirsch,  Senior Human Factors Specialist at TfNSW, said:

“Our objective is to gain data specific to the Australian population so we can design public transport that caters specifically to our shapes and sizes.

“These designs directly impact passenger comfort, safety, accessibility, and overall user experience. By incorporating anthropometric data into the design process, we can ensure that work and transport systems are more efficient, safe, and comfortable to use by our staff and customers.”

Introduction of New Clinical Care Standard by ACSQHC to Address Psychotropic Medicine Use in Cognitive Disability and Impairment

 

By Jeff Gibbs

The Australian Commission on Safety and Quality in Health Care (the Commission) has today announced the launch of a pivotal new national standard aimed at enhancing the care for individuals with cognitive disabilities or impairments. The introduction of the Psychotropic Medicines in Cognitive Disability or Impairment Clinical Care Standard is a critical advancement in promoting safer and more effective treatment protocols across the healthcare spectrum.

Background and Rationale for the New Standard

Advertisements

Recent decades have witnessed a 60% surge in the prescription of psychotropic medications across Australia. Despite a modest reduction in antipsychotic use among the elderly—prompted by heightened awareness of associated risks—the prescribing rates remain alarmingly high, particularly among vulnerable populations. Notably, older individuals and those residing in aged care facilities are disproportionately affected by the adverse effects of these medications, including cognitive decline, heightened risk of falls, strokes, and mortality. Additionally, approximately one-third of individuals with intellectual disabilities are prescribed psychotropic drugs, exposing them to potentially severe short and long-term side effects.

Scope and Impact of the Standard

The new Standard seeks to mitigate the inappropriate utilisation of psychotropic medications and emphasises patient safety. It priorities non-pharmacological interventions as the foremost approach for managing challenging behaviours such as aggression and agitation. Psychotropic medications are advised as a last-resort measure, following the ineffectiveness of alternative strategies or in situations posing significant risk to the individual or others.

The Standard advocates for tailored non-medication strategies that respect the individual’s needs and preferences, developed in consultation with their family and other authorised caregivers. This approach underscores the commitment to upholding the dignity and autonomy of individuals with cognitive impairments.

Expert Insights and Support

Key health experts have endorsed the significance of this new Standard. Conjoint Associate Professor Carolyn Hullick, Chief Medical Officer at the Commission, stresses the necessity for mindful prescribing practices given the limited benefits and substantial risks associated with psychotropic medications in this demographic. Professor Julian Trollor from the University of New South Wales and Juanita Breen from the University of Tasmania also highlight the importance of objective-driven prescribing, continuous monitoring, and the potential to reduce medication dosages in favour of non-pharmacological alternatives.

Implementation Across Settings

The Standard is applicable universally across various healthcare settings, including hospitals, aged care facilities, and community services, ensuring that individuals with cognitive disabilities receive consistent and coordinated care irrespective of the setting.

Professor Eddy Strivens emphasises the need for coordinated efforts and effective communication, particularly during care transitions, to maintain continuity and efficacy of treatment plans and to support decision-making processes that honour patient autonomy.

Collaborative Efforts for Enhanced Care

In a collective endeavour to address these issues, the Commission has collaborated with the Aged Care Quality and Safety Commission and the NDIS Quality and Safeguards Commission to issue a Joint Statement against the misuse of psychotropics in managing behaviours in disabled and elderly populations.

Conclusion

The introduction of the Psychotropic Medicines in Cognitive Disability or Impairment Clinical Care Standard marks a significant step forward in improving the quality of care and safety for Australians with cognitive disabilities or impairments. It aligns with ongoing efforts to reform health care, aged care, and disability support systems across the nation.

The complete Standard and accompanying resources are available on the Commission’s website here.

National Walk Safely to School Day Turns 25

 

As National Walk Safely to School Day approaches on Friday, 10 May 2024, primary school-aged children across Australia are encouraged to lace up their shoes for a walk towards a healthier future. Celebrating its 25th anniversary, this initiative, championed by the Pedestrian Council of Australia, highlights the myriad benefits of walking and other forms of active transportation, particularly to and from school.

This annual event not only emphasises physical health but also aims to improve road safety, reduce environmental impact, and promote the use of public transport to lessen car dependency near schools. Harold Scruby, Chairman and CEO of the Pedestrian Council of Australia, emphasises the importance of adult supervision for children under 10 when crossing the street, reinforcing the safety aspect of the campaign.

“Walk Safely to School Day is a great opportunity to teach our kids about the benefits of physical activity,” said Scruby. He also pointed to the worrying statistics of childhood obesity, which affects one in four children at critical levels across the nation, according to the latest ABS National Health Survey results from 2017-18. “The best form of physical activity for all Australians is walking regularly. Children need at least 60 minutes of physical activity a day,” he added.

The day is not just about walking; it also encourages schools and parent groups to host healthy breakfast events to start the day nutritiously. This initiative supports the dual goals of fostering healthful eating habits and providing social interaction within the school community.

As the event marks a significant milestone, schools across Australia are gearing up to participate more actively than ever. Parents, teachers, and caregivers are encouraged to get involved, not only to support their children but also to take part in making walking a regular part of their daily routine.

This initiative plays a crucial role in mitigating traffic congestion around school areas, promoting environmental stewardship, and fostering a sense of community. Everyone in the community is invited to support the initiative, helping to instil healthy habits in children that can lead to lifelong benefits.

For more information on how to participate in National Walk Safely to School Day, visit the Pedestrian Council of Australia’s website or contact your local school to see what activities are planned for the day. Join the movement on 10 May and help make a difference in the lives of young Australians.
