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 appoints Prof Francis Petersen as Vice-Chancellor and Rector

2016-12-02

Prof Francis Petersen

The Council of the University of the Free State (UFS) is pleased to announce that it has decided to appoint Prof Francis Petersen as Vice-Chancellor and Rector of the UFS.

Announcing the decision to appoint Prof Petersen today (Friday 2 December 2016) during the quarterly Council meeting on the Bloemfontein Campus, the Chairperson of the UFS Council, Judge Ian van der Merwe, said the university was fortunate to be able to appoint a candidate of such good quality to the position.

Prof Petersen, Deputy Vice-Chancellor: Institutional Innovation at the University of Cape Town (UCT), and Prof Lis Lange, Vice-Rector: Academic at the UFS, were in line for the position. The university’s Selection Committee expressed equal preference for both and the two candidates were therefore recommended to Council for the position.

“It has been a truly participatory and transparent selection process, which has assisted in the Council being able to make this decision. The higher-education sector has been through a difficult and challenging time during the past few months and the Council is thankful that a leader like Prof Petersen can head the university in 2017 and beyond,” said Judge Van der Merwe.

In his statement of intent, which was submitted earlier as part of the application for the post, Prof Petersen indicated that it is important to imagine the UFS’s location in South Africa and Africa, to realise the challenges within this context, now and in the future, so as to sharpen the university’s focus to become a more inclusive, academic excellent institution, embedded in a culture of innovation. “Therefore, the ideal of academic excellence must be supported by an institutional framework of diversity and inclusivity. The Academic Project should focus on a unique educational experience for every UFS student, the enhancement of student throughput-rate in academic programmes through dedicated academic support, graduate attributes, and curriculum change and renewal,” he said. He furthermore stated that research and innovation must focus on impact and international visibility. “It is thus not only the increase in research and innovation output, but the quality and impact thereof.”

Prof Petersen was previously the Dean of Engineering and the Built Environment at UCT. He brings to the position of Vice-Chancellor and Rector his extensive experience of management in both the industry and academic sectors. He has been the executive head of strategy at Anglo American Platinum and head of the Department of Chemical Engineering at the Cape Technikon (now Cape Peninsula University of Technology). He is a member of the UCT Council, non-executive director on the Board of Pragma Holdings, non-executive director on the Board of the Unlimited Group, and Chairman of the Board of Trustees of the Seedcap (Venture Capital) Trust. Among others, he previously served as member on the Board of the Council of Scientific and Industrial Research, the National Advisory Council on Innovation, and the Council of the Academy of Science of South Africa.

He graduated from Stellenbosch University with a BEng (Chem Eng), MEng (Metal Eng), and PhD (Eng) degrees and completed a short course on Financial Skills for Executive Management. He is a recipient of the Ernest Oppenheimer Memorial Trust Award for research excellence, and was visiting professor at the Cape Technikon and extraordinary professor in the Department of Chemical Engineering at Stellenbosch University. He is a regular reviewer of journals, and member of a range of editorial boards for international journals.

Prof Petersen is also a registered professional engineer with the Engineering Council of South Africa and a Fellow of both the South African Institute of Mining and Metallurgy, and the South African Academy of Engineers.

Prof Petersen succeeds Prof Jonathan Jansen, who stepped down as Vice-Chancellor and Rector of the UFS on 31 August 2016. An international executive search agency specialising in academic appointments has assisted the UFS Council in its search for top-quality candidates.
