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.

Change and growth at the University of the Free State
2011-07-04

“Come gather round people, wherever you roam. And admit that the waters around you have grown…”

These are the opening lines of Bob Dylan’s iconic single The times they are-a changing. They are also extremely apt words to describe the excitement about the winds of change and growth blowing across the University of the Free State, not only academically, but also physically.

Over the past few months there has been non-stop construction and growth of a physical nature, with several new buildings being erected and new sculptures rising up all over the Bloemfontein Campus.

The most visible and probably the most striking of all the new structures is the brand-new main entrance to the campus. This stunning new feature welcomes visitors to the campus in Nelson Mandela Drive, in the colours of each of the university’s seven faculties.

Once through this beautiful new gate, visitors have a choice of new and exciting features to explore on the campus.

The first is the brand new climbing wall, which is located against the West Block and Chemistry Buildings. This new addition to the campus is available for use by all enthusiasts of this exciting sport.

The Office of the Dean of Student Affairs manages the administration of the wall and students who want to climb can book at their office in the Student Centre at the Thakaneng Bridge. In order to ensure that students do not use the wall without permission, and to prevent accidents, the wall is covered by a tarpaulin, which is locked when the wall is not in use.

Next on the list of new developments is the high-performance gymnasium which is currently still under construction. With this project the university wants to create a work environment for its staff that will not only contribute to the cultivation of maximum work performance, but also to staff wellness.

The centre with its foyer and administrative offices will also consist of a health desk, university sports institute, sports sales, a spinning and aerobic centre, and dressing rooms. The total area will extend more than 2114 m².

Progress on other building projects, which commenced last year, is also very pleasing. One of the projects is a new Education Building which is being constructed opposite the UFS Sasol Library. Upon completion, this building will be used for the training of maths and science teachers in the Foundation Phase. It will include three classrooms for 100 students each and an auditorium for 225 students as well as an office block. The auditorium will also be used as a classroom. The building has been designed according to environmentally friendly principles to save water and use power effectively. Construction is going swimmingly and should be completed soon.

Planning for the construction of more student accommodation on the Bloemfontein Campus as well as the Qwaqwa Campus is also well underway. On the Qwaqwa Campus, a residence with 200 beds is being constructed. This also includes a computer laboratory. According to the planning, this residence is near completion. Furthermore, four residences will be constructed on the Bloemfontein Campus. These residences are in the planning phase.

In order to place technology within reach of Kovsie students and thereby empowering them, computer laboratories were installed at all residences. The computer laboratories will eventually make provision for approximately185 computers for student use. Proper security is also planned to safeguard the equipment.
A brand-new building for the Faculty of Health Sciences is also proceeding rapidly. This building will include a lecture hall for 200 students, five venues for 100 students each, as well as offices. Students from the School for Medicine and Occupational Therapy will make use of these facilities.

The new building for the Faculty of Economic and Management Sciences between the Flippie Groenewoud Building and the Wynand Mouton Theatre is also coming along nicely.

On the university’s Qwaqwa Campus a new Education building is being constructed. This building will include a lecturing hall with 100 seats, four 50-seat classrooms, six offices, ablution facilities, biology and science laboratory, as well as an information technology laboratory for 60 students.

In the meantime, existing buildings are being renovated on all the campuses. This includes, amongst others, improvements to the Architecture Building, the Biotechnology Building and the quarters for service workers on the Bloemfontein Campus. Other improvements that have already been completed include renovations to the Odeion’s foyer and the Callie Human Centre.

A special memorial park for women, residential accommodation within a sports environment, and a botanical garden are also among the beautiful, exciting new sites to be seen on the campus.

Coupled with all the beautiful sculptures, funded by the Lotto Sculpture project, our university’s campuses will soon be a more vibrant, beautiful attraction.
