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 seals cooperation with National Institute for Higher Education

A formal memorandum of understanding was recently signed between the University of the Free State (UFS) and the National Institute for Higher Education in the Northern Cape (NIHE).

The memorandum was signed to give both institutions a clear understanding of the way in which collaborative programmes should be implemented.

“Although the UFS has been presenting two bachelors degree courses (i.e. B Soc Sc in Human and Societal Dynamics and B Com in General Management) and the Career Preparation Programme at the NIHE since 2003, the cooperative agreement was never formalised,” explained Prof Magda Fourie, Vice-Rector: Academic Planning at the UFS, during the signing ceremony.

These academic programmes, presented by facilitators living in Kimberley and lecturers from the UFS, serve 270 students and the entry requirements of the programmes are determined by the UFS.

Prof Fourie said the UFS had a history of a relationship with the NIHE. The partnership should be seen as an example of how two institutions of higher learning can work together to serve the needs of the students in the region.

“The memorandum of understanding is part of the UFS’s commitment to and engagement with the central region. As the NIHE is currently operating in a policy vacuum, the memorandum is underpinned by certain principles aimed at providing some parameters within which the relationship is established and developed,” she said.

Dr Kopano Taole, acting head of the NIHE, added to this by saying that the understanding of where the NIHE wants to take the partnership is now reflected in the memorandum of understanding.

“The memorandum is the culmination of many years of hard work and of helping the people of the region. The continued input and guidance of the UFS is of tremendous help to us and through this we gained a greater sense of what the NIHE can grow to be,” he said.

The NIHE is a joint initiative of the BHP Billiton Development Trust (BBDT) and the Northern Cape Provincial Government and was established in June 2004. The National Plan for Higher Eduation (NPHE 2001) proposed the establishment of the NIHE in the Northern Cape to serve as the administrative and governance hub for ensuring the coherent provision of higher education through programme collaboration between the higher education institutions operating in the Northern Cape.
