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.

The Faculty of Health Sciences of the University of the Free State (UFS) has, as part of its commitment to student and community development, established a student residence in the town of Trompsburg in the Kopanong Local municipality, Xhariep District municipality in the Southern Free State. The Faculty officially opened the Faculty of Health Sciences Rural Community Initiative on 14 and 15 June 2017. The memorial plaque was unveiled by Prof Gert van Zyl (Dean of the Faculty of Health Sciences) and Prof Francis Petersen (Rector and Vice-Chancellor of the University of the Free State)

The importance of the residence

The goal of the ‘Kopanang le fodise – Unite to heal’ programme is to develop a community-centered collaborative framework for sustainable, holistic healthcare and social development incorporated in the curricula of the Faculty.

Background of the project

During 2016 a total of 324 fourth-year students of the Faculty have each spend at least a week in interprofessional groups in primary healthcare facilities in the Kopanong municipality on a Community Based Education, Interprofessional Education (CBE-IPE) platform in Trompsburg and Springfontein.

To facilitate student rural placement the former Midway guesthouse currently includes seven (7) facilitator units with on suite bathrooms, two (2) fully equipped lecture facilities, a recreation room and a library with computers and internet access. The newly developed student residence has 10 apartments that can each accommodate six (6) individuals. A housemaster resides on the premises and acts as manager of the facility. All areas of the residence are Wifi covered and 24h security service is in place.
