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 academics serve high in ranks of Cereal Science institutions
2017-10-10

Description: Cereal Science Tags: Cereal Science

Dr Angie van Biljon, Senior Lecturer in the Department of Plant Sciences at the University of the Free State (UFS), was elected as president of Cereal Science and Technology South Africa (CST-SA) at their bi-annual general meeting, in Pretoria.

Prof Maryke Labuschagne, Professor in Plant Breeding at the UFS and official representative of South Africa in the American Association for Cereal Chemists International from 2007, was re-elected as the South African representative to the American Association for Cereal Chemists. She attends the annual conference in the US as well as the International Association for Cereal Science and Technology (the European counterpart of AACC) regularly. “I use these conferences to report on the research done by the research team at the UFS on gluten protein, baking quality and nutritional value of cereals,” she said.

Prof. Labuschagne was also involved in a training course for the baking industry. 

Both Dr Van Biljon and Prof Labuschagne are involved in research on wheat gluten proteins, which is critical to the baking industry. CST-SA is a platform to disseminate this and other research, not only locally but also internationally. The aim of this society is to advance cereal science and technology both in the public sector and in the industry of Southern Africa.

CST-SA creates an opportunity for staff and
students working on cereals to interact
with the industry. This prevents research
from being just academic and creates
an opportunity to bring the research and the
industry together.

Wheat research not just academic
According to Prof Labuschagne CST-SA creates an opportunity for staff and students working on cereals to interact with the industry. This prevents research from being just academic and creates an opportunity to bring the research and the industry together. This has been very useful for students at the university working on cereals, as they have made presentations at the “New Voices” symposium, a forum for postgraduate students to present their research.

“Through CST-SA we have also, through the years, presented our research on an international level at the annual meetings of the American Association for Cereal Chemists and the International Association for Cereal Science and Technology,,” said Prof Labuschagne.

The science of cereals
CST-SA is an association of organisations and individuals, from both the private and public sectors, who are actively involved in the science and technology of cereals. Its aim is to promote the dissemination of knowledge and information on cereal science and technology through meetings, publications, workshops and other means. CST-SA also organises training courses for the industry. In the past years there was a course for the baking industry and one for the milling industry and also the “New Voices” symposium”.
