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.

Ford foundation funds higher education redesign

2005-06-23

The Ford Foundation has pledged a grant of almost R280 000 for redesigning higher education delivery at three campuses in the Free State.

According to Prof Magda Fourie, Vice-Rector: Academic Planning at the University of the Free State (UFS), the three campuses that will be affected by the strategic reconfiguration of higher education delivery are the Qwaqwa campus at Phuthaditjhaba and the Vista campus of the UFS in Bloemfontein and the Welkom campus of the Central University of Technology (CUT).

Prof Fourie says the three campuses were all affected by the restructuring of higher education, in line with the National Plan for Higher Education.

The Qwaqwa campus of the UFS that was part of the former University of the North was incorporated into the UFS in January 2003. Likewise the Bloemfontein campus of the former Vista University was incorporated into the UFS in January 2004.

The Welkom campus of the CUT was also part of the former Vista University and was incorporated into the CUT in January 2004.

“These incorporations pose a challenge in that we have to think creatively about the best ways of using these three campuses to service the higher education, training, skills development and human resource needs of the Free State,” Prof Fourie said.

“The grant from the Ford Foundation will primarily be used to draw up strategic funding proposals for the three campuses. The Qwaqwa campus of the UFS is a priority to us given the poverty and unemployment in a largely rural area of the Free State,” said Prof Fourie.

“A detailed consultation process will be undertaken in the Qwaqwa campus sub-region which will hopefully result in a comprehensive and a coherent suite of higher education activities being established on this campus,” said Prof Fourie.

“It is envisaged that the Qwaqwa campus will become a centre of excellence in the area of rural development. This vision is based on a focused integration of the core functions of a university – teaching, research, and community service – around the issue of rural development,” said Prof Fourie.

Prof Fourie said that various educational offerings including among others short courses, bridging and foundation programmes, and degrees could be offered, with a particular focus on providing courses of relevance to students from the local rural community and students from elsewhere with an interest in focusing on rural development studies.

She said the redesign of the three affected campuses is being managed as a project of the Free State Higher Education Consortium (FSHEC) consisting of all the higher education institutions operating in the Free State.

“The aim of the project is to establish how the Qwaqwa and Vista campuses of the UFS and the Welkom campus of the CUT can be used effectively to meet regional education and training needs, to serve the strategic priorities of the two higher education institutions and contribute to the sustainable development and poverty alleviation of the region,” she said.

The planning for the Vista campus of the UFS is still in an early stage. “We are looking at the possibility of developing this campus into a hub of education and training opportunities for Bloemfontein and Free State region. Further plans will be communicated later in the year,” said Prof Fourie.
