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.

Department of English changed to empower students

A new curriculum, exciting third-year seminars, and a transition to continuous assessment. These are some of the changes made by the Department of English at the University of the Free State (UFS) over the past few years. The department, which also boasts four National Research Foundation (NRF) researchers, did this to tailor the curriculum towards the needs of its students and to foster a better culture of engagement.

According to Prof Helene Strauss, Head of the Department, the advantages of these changes are clear. “Staff have noted a significant improvement in both the basic writing and critical deliberation skills of our students, and in the responsibility they are taking for their own learning.” The new curriculum empowers students to take a position in relation to the knowledge they encounter in the classroom, thereby strengthening their own critical voice.

Taking continuous responsibility

One of the most significant changes for students was the fact that they have to take responsibility all the time. Prof Strauss says continuous assessment changed “last-minute cramming to near-daily, student-centred activities of reading, writing, and critical discovery.”

Because students have to prepare for lectures and reflect on materials, they are in a better position to internalise difficult debates and critical concepts. “Rather than telling students what to think, we help them develop flexible, critical tools to make sense of a changing world.”

Third-year seminars are another way of including forms of instruction that concentrate on the links between education and democracy, but still improve students’ ability to speak and write English accurately. Every semester, students can choose seminars from a range of topics such as ‘Witchcraft’ (Prof Margaret Raftery) and ‘The Art of Dying’ (Dr Mariza Brooks).

Research and associates around the world

Dr Marthinus Conradie, Dr Rodwell Makombe, Prof Irikidzayi Manase, and Prof Strauss are all NRF-rated researchers in the department.

The department also has affiliated research associates from countries including Zimbabwe, the USA, and Canada. Dr Kudzayi Ngara currently holds a competitive NRF grant for a project on Southern African urbanity, and Dr Philip Aghoghovwia recently received the prestigious African Humanities Programme Fellowship.

Under the guidance of Dr Ngara, the department has been able to roll out a new Honours programme on the Qwaqwa Campus. The campus now also offers students the opportunity to pursue MA and PhD studies.

Other highlights:
• Hosted the international Institute of the Association for Cultural Studies in 2015.
• Books published: Dr Susan Brokensha (with Burgert Senekal). Surfers van die Tsunami: Navorsing en Inligtingstegnologie binne die Geesteswetenskappe (SUN MeDIA, 2014); Prof Iri Manase. White Narratives: The depiction of post-2000 land invasions in Zimbabwe (UNISA Press, 2016); as well as co-edited volumes with Cambridge Scholars Publishing (Dr Oliver Nyambi) and Routledge (Prof Helene Strauss).
• Publications include three special journal issues (of ISI journals Critical Arts: South-North Cultural and Media Studies; Safundi: The Journal of South African and American Studies; Interventions: International Journal of Postcolonial Studies).
