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.

Prof Riaan Luyt, professor in Chemistry and head of the Natural Sciences Programme at the Qwaqwa Campus of the University of the Free State, received an honorary medal from the Polymer Institute of the Slovak Academy of Sciences on Monday 29 September during a conference in the High Tatras mountains of Slovakia.

During the event Prof Luyt also presented a lecture entitled ‘Paraffin wax in polymer blends and composites: Is it worth investigating?’. In this lecture he gave an overview of the research that he and his group did over a period of 10 years in collaboration with scientists at this institute. The results of this research was published in eighteen international papers and one research book chapter.

Prof Luyt’s research at the Qwaqwa Campus involves polymer blends and composites, and he has already published 82 papers in international, peer reviewed journals, as well as two book chapters. At present his research group consists of nine doctoral and five master’s degree students, as well as a postdoctoral fellow. The postdoctoral fellow is from Nigeria, and one of the doctoral students is from Sudan.

Prof Luyt and his group collaborate formally internationally with groups in Kottayam (India), Modena (Italy), Budapest (Hungary) and Bratislava (Slovakia). He also collaborates informally with groups at the Universities of Pretoria and Stellenbosch, and with a group in Johor Bahru (Malaysia).

He previously received recognition for his research from the Faculty of Natural and Agricultural Sciences at the University of the Free State (Award for Outstanding Research in 2005) and from the Qwaqwa Campus of the UFS (Jubilee Medal and Certificate for Outstanding Research in 2007).
