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 discontinues one Masters programme

2006-07-26

As from next year, the University of the Free State (UFS) will no longer offer one of its specialist master’s degrees in education – the M Ed in Education Management.

The other six M Ed programmes that are currently being offered at the UFS will continue as normal.

The decision to discontinue one of the M Ed programmes follows a national review of M Ed programmes in Educational Management and Leadership by the Higher Education Quality Committee (HEQC) of the Council on Higher Education (CHE).

Of the 23 tertiary institutions whose M Ed programmes in Educational Management and Leadership were reviewed by the HEQC, only 7 received full accreditation.

“The findings of the HEQC affect only one of our M Ed degree programmes, namely the M Ed in Educational Management,” said Prof Magda Fourie, Vice-Rector: Academic Planning at the UFS

“We will be paying full attention to the findings of the HEQC with a view to correcting some of the shortcomings that have been identified by the HEQC and will consider submitting a reviewed proposal for such a qualification in two years time,” she said.

According to Prof Fourie, the programme currently has 30 students enrolled. “These students – spread across their first and second years of the degree programme – will be allowed to complete their studies with the full support of the UFS and the School of Education,” said Prof Fourie.

“The qualification that has been awarded to students who have already completed their studies for this specific M Ed in Education Management degree programme remains a valid qualification and is not affected by the HEQC review,” said Prof Fourie.

She said the UFS welcomed the efforts of the HEQC to ensure that all academic programmes offered by higher education institutions meet certain standards.

“One of the primary problem areas in the M Ed in Educational Management offered by the UFS identified by the HEQC, was that the programme is too practice orientated and must be more theoretical to comply with the academic requirements of a master’s degree. This was a result of the fact that the programme was initially compiled in consultation with principals and the provincial Department of Education to address their needs,” said Prof Fourie.

“The UFS will in the mean time offer an advanced certificate in Educational Management and Leadership from next year. This is a new course that will stretch over a period of two years and will ensure that we can still address the needs of teachers and principals,” said Prof Fourie.

“The UFS remains committed to providing top quality degree programmes in all its six faculties and will continue to work with the HEQC in ensuring that this actually happens,” said Prof Fourie.
