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 shines in MBA survey
According to a recent survey published in the Financial Mail, the MBA programme presented by the School of Management at the University of the Free State (UFS) was rated jointly second best in the country by its graduates in terms of quality and standard.
The UFS MBA Programme was also rated fourth best by its graduates in terms of relevance to their business.

“I am overwhelmed and very proud that the School of Management, although we are a young school and have only been in existence for 7 (seven) years, has been rated so high by our graduandi. The School contributes in a very special way to much-needed business training in central South Africa,” said Prof Helena van Zyl, Director of the UFS School of Management.

“According to the survey, we have the lowest acceptance rate of applicants for the MBA programme, with only 33 students being accepted out of every 100 who apply. In general, we do not compromise on quality – as stated by our slogan: Be worth more. Given the quality of the programme, our MBA is very affordable – it offers real value for money,” said Prof van Zyl.

According to Prof van Zyl, the School of Management has had an increase the past 6 (six) months in enquiries from prospective students from Gauteng who are interested in studying the MBA programme. “They are even prepared to travel to Bloemfontein to attend classes,” she said.

This year Financial Mail moved away from an overall MBA ranking to a detailed consideration of subject area strengths for each business school in South Africa. The subject Strategy offered at the UFS School of Management was rated second in the country while the subject Economics also received the same rating.

“The School of Management is the flagship of the Faculty of Economic and Management Sciences. It gives the UFS and this faculty a standing in corporate South Africa. This is largely due to Prof Helena van Zyl’s strategy to position the school and making it visible on a national level,” said Prof Tienie Crous, Dean: Faculty of Economic and Management Sciences at the UFS.

According to Prof Crous, the UFS School of Management provides students with opportunities to obtain first-hand experience of how big and successful companies are managed. “For instance, our MBA students undertake an overseas study tour every year. This year they visited amongst others the headquarters of Airbus in Toulouse, France and next year they will be visiting the headquarters of Toyota and Yamaha in Japan,” said Prof Crous.
