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.

Law students rated among the top in the world

UFS Law students rated among the top in the world

A team of eight students from the Faculty of Law at the University of the Free State (UFS) has put the university among the top universities in the world when it was ranked 46th out of 177 universities that recently took part in the Willem C. Vis International Commercial Arbitration Moot competition in Vienna, Austria.

Universities from more than 55 countries took part in the competition and 1 800 arguments were delivered over a period of seven days. The UFS team competed against countries such as Switzerland, Russia, Lapland and France.

The team did exceptionally well in all the arguments and was complimented on oral performance and litigation skills. “In the final round, one of the arbitrators, who is a practising international trade lawyer and arbitrator, said that the team’s oral arguments were of exactly the same standard as that of practising international trade lawyers in real arbitrations,” said Prof. Elizabeth Snyman-Van Deventer, coach of the team and lecturer at the Department of Mercantile Law.

To put the cherry on top, one of the team members, Deman Smit, received an individual oralist award and an honourable mention as one of the best speakers. His score of 138 out of 150 placed him within three (3) points of the international individual winner.

The Dean of the Faculty of Law, Prof. Johan Henning said: “The fact that Deman missed out on receiving the top speaker award by a couple of points is a striking example of the world class students this faculty is delivering. It also shows that the faculty needs not to stand back for law faculties such as those of Harvard, Freiburg, Munchen, Stanford and Sorbonne.”

The Willem C. Vis International Commercial Arbitration Moot is an annual competition organised by the Institute of International Commercial Law at the Pace University School of Law in New York, United States of America. The goal of the competition is to foster the study of international commercial law and to train students in methods of alternative dispute resolution.

“The Faculty of Law also sees this competition as part of our development strategy to develop skilled arbitrators for commercial disputes. There is a need in Africa for commercial lawyers to facilitate international trade. This programme is also in line with the development strategies of the African Union,” said Prof. Snyman-Van Deventer.

The UFS team comprised of: Dee Leboela, Smit, Lucien Companie, Vicky Olivier, Sunette Visser, Qaqamba Vellem, Hanno Bekker and Lucy Nthotso.
