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.

Schae-Lee Olckers, a master’s student in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS), will be travelling to the US in a few weeks’ time. For the next two years she will be doing research at the Michigan State University (MSU) at its Department of Food Science, working on wheat quality and its baking properties.

Increase the nutritional value of maize
The title of her master’s research project is: “The influence of low and optimal nitrogen conditions on the nutritional value of quality protein maize”. She is focusing on the influence of environmental conditions on the nutritional value of maize.

New hybrids of maize production developed

Olckers said: “I chose to start my research on this specific topic in my honours year because maize is the main staple crop in South Africa, as well as in the rest of Africa. Therefore, micronutrient malnutrition is a major concern for developing countries as well as for poor people who rely on it as a major food source. I found it interesting that these breeding programmes that are being developed for new hybrids of maize for production are focusing on increasing the nutritional value of maize and can therefore help eliminate micronutrient malnutrition in some populations of poor communities,” she said.

Prof Perry Ng will be her research supervisor. He is an affiliated professor at UFS in the division of Plant Breeding. “I am very excited about the opportunity to travel and to gain experience working with a well-known cereal scientist. The work he does is also closely associated with my research,” said Olckers.

Her supervisors at UFS are Profs Garry Osthoff and Maryke Labuschagne from the Departments of Microbial Biochemical and Food Biotechnology and Plant Sciences respectively.
