Infant body composition research revolutionised with new PEA POD® technology

Prof Corinna Walsh says the PEA POD Infant Body Composition System works by directly measuring an infant’s body weight and volume, and then uses these measurements to calculate the body fat percentage, fat mass, and fat-free mass.

Nutritional and growth patterns during early life have been associated with health, development, and well-being throughout the life cycle. It is also associated with risks for developing obesity and non-communicable diseases, such as cardiometabolic diseases, later in life. These are the findings of Prof Corinna Walsh, Professor in the Department of Nutrition and Dietetics.

Maternal and child health

”In line with national priorities, a strong research focus area of the Faculty of Health Sciences and the School of Health and Rehabilitation Sciences is maternal and child health,” she says. She goes on to mention that the Department of Nutrition and Dietetics has established a reputable research programme. This programme focuses primarily on the nutritional status of pregnant women and how the early environment to which they are exposed during and after pregnancy affects short- and long-term health outcomes of the offspring.

“In our previous work, the assessment of birth outcomes of infants was, however, limited by the lack of equipment to analyse body composition. The research that we can conduct with the PEA POD® provides us with immense additional potential,” remarks Prof Walsh.

She explains, “The PEA POD Infant Body Composition System is an infant-sized air displacement plethysmography system. It works by directly measuring an infant’s body weight and volume, and then uses these measurements to calculate the body fat percentage, fat mass, and fat-free mass.

According to her, the assessment of body volume takes two minutes. “The PEA POD technique also does not require collection of any fluids and does not expose the infant to radiation. It can be performed as often as required without any risks and be used up to a maximum of 8-10 kg body weight, from birth to about eight months,” she says.

Advanced technology

In the context of research on infant body weight and composition, there is a need for accurate measurement techniques that can differentiate between fat mass and fat-free mass. Prof Walsh is of the opinion that traditional measures such as body mass index (BMI) and weight for length have limitations in this regard, as they do not provide a clear distinction between these components. Furthermore, BMI may not be reliable for assessing adiposity or obesity in paediatric populations, and it can vary significantly with age and gender.

Addressing these challenges, the PEA POD equipment offers advanced technology that allows for highly accurate quantification of infant body composition. This technological capability opens up opportunities to study the effects of early-life nutrition on growth and the developmental mechanisms that may lead to later comorbidities. So, when it comes to researching infant body weight and composition, the PEA POD equipment plays a crucial role in providing precise data and insights.

UFS finances are fundamentally sound

2007-12-01

The finances of the University of the Free State (UFS) remain fundamentally sound and a higher than expected surplus of about R26 million was achieved in the 2007 budget.

This announcement was made last week during the last meeting of the UFS Council by Prof. Frederick Fourie, Rector and Vice-Chancellor.

“Up to now, we could finance the considerable investments in the infrastructure from discretionary funds, in spite of the fact that Council granted us permission during 2005/06 to take up a loan of R50 million for this purpose,” said Prof. Fourie.

The higher than expected surplus of about R26 million will be used among other things for the financing of infrastructure in order to further postpone the taking up of a loan.

In support of the drive to reposition the UFS nationally as a university that is successfully integrating excellence and diversity, R5 million will be made available from the surplus for this purpose.

The Council also approved the following allocations for 2008 for the key strategic pillars of a good practice budget for the university:

Information sources: R21,1 million
IT infrastructure: R3,5 million
Replacing expensive equipment: R7,05 million
Research: R18,1 million
Capital expenditure: R28,2 million
Maintenance capital assets: R18,2 million
Reserves: R6,3 million
Personal computers for the computer laboratory: R3,5 million

For the Qwaqwa Campus R2,5 million has been set aside for these issues.

In terms of strategic priorities R8 million was allocated for the academic clusters, R2 million for equitability, diversity and redress and R6 million for equity.

The projected income for 2008 will be R849 million, while the projected expenditure, excluding transfers, will be R694 million.

“Council further approved that discretionary strategic funds be largely voted to the further upgrading of the physical infrastructure, especially the Chemistry Building, the computer laboratory building, examination venues and the Joolkol,” said Prof. Fourie.

According to Prof. Fourie, funds have been reserved for the development of the academic clusters, as well as the continuation and acceleration of the transformation programme of the UFS.

“We have also managed to revise the conditions of employment of contract appointments and align it with the latest labour practices. The phasing in of the fringe benefits of this specific group of staff members will commence in 2008,” said Prof. Fourie.

Given the dependence of the income of the UFS on student numbers, a task team was formed last year to investigate the continued financial sustainability of the UFS. The core of this task team’s recommendations is:

to increase the third income stream by using the academic clusters as the main strategy; and to apply strategies such as the recruitment and extension of the postgraduate and foreign student corps, increase the income from donations and fundraising, etc.
