Infant body composition research revolutionised with new PEA POD® technology

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.

Centre for Human Rights at UFS geared to make impact in the region

After approval by the Rectorate, Senate and Council of the University of the Free State (UFS), the Free State Centre for Human Rights (FSCHR) began operations on 1 January 2016 on the Bloemfontein Campus, under the leadership of Prof Leon Wessels, founding member of the South African Human Rights Commission (SAHRC) as the Acting Director of the centre.

Human rights remain, undoubtedly, the dominant moral and political language of our times and thus demands multi-layered scholarly engagement as it influences national and international relations, and sets standards for political and democratic practice.

Establishment of centre fulfilment of court order
Top on the centre’s agenda will be to resolve the debate with the SAHRC relating to the February 2011 post-Reitz agreement of the UFS, which was subsequently made an order of the Equality Court. This order compelled the UFS to establish such a centre. The FSCHR presents new opportunities for cooperation between the FSCHR, the SAHRC and other stakeholders to the benefit of the UFS and the broader community.

Three divisions of the centre to achieve its mandate
The centre consists of three inter-related divisions with the potential to stimulate critical scholarship in the field of human rights through its postgraduate and research division. This is reflected in the centre’s mission to deepen the study of human rights and further its praxes by developing novel methodologies in which traditional human rights issues can be complemented by interdisciplinary and multi-disciplinary approaches.

The Advocacy division of the centre will promote human rights among UFS staff and students, and the surrounding community. The aim is to establish a vibrant human rights culture in and across all campuses in which rights of all are respected and protected.

The Legal Services division will provide trustworthy legal services to individuals and groups whose fundamental rights have been abused, to improve the professional capacity of paralegals, students, counsellors, social workers, candidate attorneys and attorneys, equipping them to deal with cases of infringement of constitutional and human rights and to increase access to justice to rural and indigent communities in the Free State.

Centre key in positioning UFS as a regional leader in human rights issues
The centre, with its inter- and multi-disciplinary approach, has the potential to become one of the flagship projects of the UFS, and will strengthen both the Academic and Human Projects. A UFS human rights centre not only makes sound scholarly and practical sense, it also has limitless symbolic value. The location of one of UFS’s campuses within the city of Bloemfontein (the judicial capital of South Africa) and having partnered with the National University of Lesotho (NUL), is historically and geographically significant. This has a great impact on the UFS, the Free State province as a whole, and the Kingdom of Lesotho.

The FSCHR will be officially launched on 14 March 2017 with Professor Bongani Majola, newly elected chairperson of the SAHRC, as guest speaker.
