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.

SAFOS seeks to integrate folklore studies into education

The University of the Free State was proud to host the national conference of the Southern African Folklore Society which took place on 7-9 October 2015 on the Bloemfontein Campus. The focus of the conference was on how to integrate folklore studies into the 21st century.

Keynote speakers for the conference included Prof Antoinette Tidjani-Alou (Professor of French and Comparative Literature at University Abdou Moumouni), Prof Mogomme Alpheus Masoga (University of Venda), and Prof Mohlomi Moleleki (University of the Free State).

The speakers approached their subjects in great detail, tackling issues surrounding identity, social cohesion, and orality on the African context. One of the main co-ordinators of this event, Dr Elias Malete from the Department of African Languages at the UFS, highlighted one of the speaker’s topics, which focused on the importance of harnessing a collectivistic culture, as the African context does not entertain individualism. When asked about how such a conference fits into the UFS context, and where it could be applied, Malete mentioned the burning issue of the language policy review. He believes that: “The language should be inclusive, in as much as our theme says we cannot entertain individualistic approaches, but need to include everybody.” This is achieved through working with the Language Departments,” he said.

In particular, the topic presented by Prof Moleleki from the Department of African Languages, explored how the self-perception of an African, both as an integral member of his society as well as an independent individual, not only informs but also underpins his identity.

In all the topic discussed, the importance of coherence, transparency, and correctness was noted.
