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.

Institute for Reconciliation and Social Justice: cultivating humanity
2014-12-15

Directors of university centres focusing on Social Justice, Diversity and Transformation met at the UFS to establish the Directors' Forum. The forum discussed the state of higher education transformation in South Africa  The forum consists of (from the left) Mr Allan Zinn from the The Centre for the Advancement of Non-racialism and Democracy at the Nelson Mandela Metropolitan University, Profs Melissa Steyn from Wits University's Centre for Diversity Studies,  Andre Keet Director of the The Institute for Reconciliation and Social Justice at the University of the Free State; Rozena Maart  from The Centre for Critical Research on Race and Identity  at the University of KwaZulu Natal and Mr JC van der Merwe, researcher at the UFS Institute for Reconciliation and Social Justice

The Institute for Reconciliation and Social Justice at the University of the Free State (UFS) provides a critical space that brings different voices, ideas and practices together to advance the Human and Academic Projects of the university. Students, staff and community members meet here to find ways to engage with diverse views, realities and aspirations.

“We cultivate humanity so that reconciliation and social justice can be expressed in our everyday life and we work against disrespect and inequalities on our campuses and in our society,” says Prof André Keet, Director of the Institute for Reconciliation and Social Justice.

“Through our various critical conversations, public lectures, seminars and colloquia, fresh understandings and ideas come to the fore and new inclusive ways of doing life in a local and global multicultural society are invented,” Prof Keet says. A host of international experts formed part of the institute’s events during 2014.

Dr Charles Alexander (University of California), Prof Halleh Ghorashi (Vrije Universiteit Amsterdam), Prof Alex Hinton (Rutgers University), Dr Shirley Anne Tate (University of Leeds) and Prof Susan Spearey (Brock University) were but a few of the international experts contributing to the work of the institute during the last year.

“We play key roles in transformation debates within Higher Education South Africa (HESA) and ministerial processes,” Prof Keet says. “We promote, protect and monitor human rights across our campuses and are frequently requested to support the work of the South African Human Rights Commission and to provide advice to other state agencies.”

The institute prides itself on their leading-edge research on social cohesion, reconciliation, human rights and higher education transformation. In addition, staff of the institute teaches, on invitation, at various faculties, as well as at other national and international universities.

To further bolster their impact, the institute is launching three master’s and doctoral postgraduate programmes in January 2015.
