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.

Dean of the Faculty of Law delivers farewell lecture
2013-12-04

Prof Johan Henning, Dean of the Faculty of Law at the University of the Free State (UFS), delivered his farewell lecture during an event attended by distinguished guests from law circles in Bloemfontein, staff from the faculty, as well as family and friends.

The topic of his farewell lecture was: From leonine to universal partnerships. This theme was also the focus of his inaugural lecture and his later research. “It was a privilege to have been part of the development of universal partnership law,” Prof Henning said.

During the event, Prof Henning was honoured by colleagues, as well as members of the law profession, for his contribution to the academy. Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, thanked Prof Henning for his part in preparing a new generation of academics for the future.

Prof Elizabeth Snyman-Van Deventer from the Department of Mercantile Law, described Prof Henning as someone with an excellent knowledge of history, especially with regard to the Anglo-Boer War and the World Wars. “He is also one of only a few academics of which four postgraduate students became professors. He has lots of empathy with other people and, despite his long list of academic achievements, he is a very humble man. Two of his outstanding characteristics are his humanity and his modesty,” said Prof Snyman-Van Deventer.

Judge Faan Hancke, former chairperson of the UFS Council and Judge of the Supreme Court, said Prof Henning is a multi-faceted person. “He is an incredible academic who has published widely and is the author of several textbooks. He is also editor of a number of journals and serves on the editorial board of several publications. I have great admiration for his academic excellence and his absolute knowledge of partnership law. He is the best in South Africa and is also highly regarded internationally in this aspect of the law (he was, among others, director of the Centre for Comparative Partnership and Company Law at the Institute of Advanced Legal Studies of the University of London). He is the ideal academic, who has achieved the highest rating in his specialist field of Mercantile Law in South Africa, namely a B1 received in 2012, and he is an excellent dean,” Judge Hancke said.

Prof Henning has a long association with the UFS. In 1968 he reported as a first-year student. Later, in 1974, he was appointed in the Department of Mercantile Law on a temporary basis. In 1998 he was appointed as Dean of the Faculty of Law. Some of the highlights in his career include his appointment as African representative of CIDOEC, Jesus College, Cambridge, and becoming the first South African being awarded an honorary fellowship to the Society of Advanced Legal Studies in Brittain, as well as the American Order of the Coif.

Prof Henning will continue his partnership with the university in 2014, acting as dean and continuing his research.
