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.

Another boost for sport at the UFS

2005-10-13

A contract formalizing the appointment of Sports Plan (Pty) Ltd was signed by Prof Verschoor and Mr Morne du Plessis in the historic Main Building of the UFS Bloemfontein campus.

The University of the Free State (UFS) has officially appointed Sports Plan (Pty) Ltd, which has former Springbok rugby captain Morné du Plessis as managing director, to manage its Centre for Exercise and Sport Science Services (CESSS) on the Bloemfontein campus.

According to Prof Teuns Verschoor, Vice-Rector: Academic Operations, the appointment of Sports Plan (Pty) Ltd is another step in the implementation of the UFS’s wide-ranging sport strategy to improve sport facilities and elevate formerly marginalized sports such as soccer, hockey, netball, tennis etc.

Sports Plan (Pty) Ltd is the manager of the Sports Science Institute of South Africa and coordinates and manages the national basketball high-performance programme of SA Basketball, as well as the Boxing Academy on behalf of Boxing South Africa.

“It is also actively involved with the sports plans of several tertiary institutions like that of the University of Johannesburg and the University of Stellenbosch,” said Prof Verschoor.

“Sports Plan (Pty) Ltd was also appointed by the Ministry of Sport and Recreation to manage the allocation of sports codes to high-performance centres and to oversee the allocation of monies received from the National Lottery to these centres – this includes the CESSS at the UFS,” Prof Verschoor added.

In unfolding its national sports plan, the Ministry of Sport and Recreation has already identified the UFS-based CESSS as the high-performance testing centre for the national basketball teams whilst the national boxing teams are also earmarked to be trained at the UFS.

“We are glad to be associated with a company of this stature and look forward to work with them in the further development of sports at the UFS,” said Prof Verschoor.

According to Prof Verschoor, the CESSS will act as a centralised body that is responsible for the coordination and management of joint initiatives between professional service providers, research projects and KovsieSport.

“The centre will also coordinate and manage joint initiatives between various academic programmes in different academic subject fields such as sports medicine, bio kinetics, physiotherapy, dietetics, etc. ,” said Prof Verschoor.

These initiatives will help the UFS to become a centre and catalyst of sports development, to become internationally recognised in the field of exercise and sports science research and to become a centre for high quality sports performance enhancement.

Some of the objectives of the CESSS are:

To provide sports science services like to athletes, students, the general public and other stakeholders including certain national sport teams.
To provide the necessary teaching and training facilities and internship opportunities for UFS students in sports related fields of study will also be provided by the centre like human movement science.
To present skills-transfer programmes directed at the broader community like development of skills in various sporting codes.
To continue and extend the current chronic risk reversal programmes presented by the Department of Human Movement Science such as obesity management, cardiac rehabilitation and other lifestyle related conditions.

The centre was founded in 2003 and was until now managed by Dr Louis Holtzhausen, from Kovsie Health and a consultant, Dr Gary Vorster.

A contract formalizing the appointment of Sports Plan (Pty) Ltd was signed today by Prof Verschoor and Mr Morne du Plessis in the historic Main Building of the UFS Bloemfontein campus.

The manager of the centre appointed by Sports Plan (Pty) Ltd is Mr Charles Store, an alumnus of the UFS, previously employed at the Sports Science Institute in Cape Town and by the SANDF at 3 Military Hospital, Bloemfontein.
