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.

An exceptional year at Kovsies — one of the most successful years in academic achievement
2014-12-04

 

The University of the Free State (UFS) had an exceptional year, with many staff members and students performing both nationally and internationally. Considerable progress has also been made in improving the academic standards of the university.

“So far, this has been one of the most successful years in academic achievement. The UFS now has the highest academic pass rate in years, partly as a result of the admission standards which were raised four years ago.

“We now also have the highest rate of research publications, one of the highest publication figures for scholarly books in history, three Mandela Rhodes scholars and several international communication awards”, says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

“The university now attracts top professors from all over the country and other parts of the world and for the first time in many years, two researchers received A-ratings from the National Research Foundation (NRF). This is the first time in the history of the UFS that two A-ratings were awarded simultaneously. The most researchers ever were rated by the NRF this year. After the constant turmoil of a few years ago, Kovsies has now become one of the most stable campuses in South Africa,” Prof Jansen says.

The impartial findings of a recent survey of UFS stakeholders showed that our values are endorsed by 92%; 86% agrees with our vision; 81% agree with our goals; 77% agree with our transformation; 78% believe that we are inclusive; and 78% applauded our overall reputation index. “These figures are very different from a few years ago when the university experienced a crisis,” he says.
 
According to Prof Jansen, the UFS’s financial situation is one of the most stable of all universities in South Africa, with a strong balance sheet and growing financial reserves – way better than before. This is exactly the reason why the UFS received confirmation from the Independent Regulatory Board of Auditors (IRBA) this year that we complied with international standards of reporting for the financial year which ended on 31 December 2013.

“I am also pleased to report that the crisis in the delivery of health services in the Free State province has been resolved due to collaboration between the UFS Management (including the Dean: Health Sciences and Head of the School of Medicine), the Department of Health and the Premier, Mr Ace Magashule. Although the loss of skilled personnel is still a concern, the Dean and Head of the School of Medicine are recreating the Health Services Platform at Universitas Hospital. However, the academic training of no undergraduate medical student or any student in the Health Sciences was influenced by the crisis in the Universitas and Pelonomi Hospitals”, he says.

The UFS is regarded around the world as a model of transformation and reconciliation in the student body. The recent SRC elections are only the most visible example of how far we have come in terms of leadership diversity. “Not a week goes by in which other universities, nationally and abroad, do not come to Kovsies to consult with us on how they can learn from us and deepen their own transformations, especially among students”, Prof Jansen says.

“The UFS will continue its model of inclusive transformation which provides opportunities for study and for employment for all South Africans, including international students and colleagues. We remain committed to our parallel-medium instruction in which Afrikaans remains a language of instruction; we are in fact the only medical school in the country that offers education and training in Afrikaans and not only English. We provide bursaries and overseas study opportunities to all our students, irrespective of race. And our ‘future professors’ programme is richly diverse as we seek the academic stars of the future. But we remain steadfast in our goal of making the UFS a top world university in its academic ambitions and its human commitments,” Prof Jansen says.
