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.

Forgive and forget? Or remember and retaliate?
2015-10-08

Cover of the novel Kamphoer

Fact and fiction came together at the Bloemfontein Campus recently to discuss the traumatic repercussions of the South African War. The event forms part of a three-year project – headed by Prof Pumla Gobodo-Madikizela (University of the Free State Trauma, Forgiveness, and Reconciliation Studies) – which investigates transgenerational trauma in the aftermath of the South African War.

The discussion explored the theme, ‘Working through the Past: Reflections on the novel Kamphoer’.

Together, Emeritus Prof Chris van der Merwe (University of Cape Town) and the author of the novel, Dr Francois Smith (University of the Free State, Department Afrikaans and Dutch, German and French), engaged in a thought-provoking, insightful conversation, tracing themes of trauma and issues of forgiveness presented in Kamphoer. Prof Van der Merwe and Dr Smith demonstrated how both fiction and historical fact can inform our present, and guide us into the future.

current issues of transgenerational trauma.

“On a societal level,” Prof Van der Merwe said, “we need to work through trauma by putting it into words, and putting it into a narrative.” When it comes to historical trauma, should we forgive and forget, though? Or rather remember and retaliate? Neither, proposed Prof Van der Merwe. “What I want to plead for is the difficult challenge: remember and forgive.” But Prof Van der Merwe also pointed out that, although forgiveness blesses both the giver and receiver, it is an ongoing process.

Dr Smith agreed wholeheartedly. “One of the discoveries of my book is that forgiving is a continuous process. It’s not something that gets completed at a particular stage in your life. By the same token, you can’t say that you are ever able to leave the past behind.” These issues of trauma, forgiveness, the past versus the present, remembering and forgetting are all integral questions confronting the main character of the novel, Susan Nel .

They are also questions we, as a nation, are currently confronted with, too.

“At this moment in our society,” Prof Van der Merwe said, “we have enough killers. We have a greater need now for caring nurturers.”
