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.

UFS application figures show a good upward trend
2008-10-23

Applications for admission to the University of the Free State (UFS) are showing an upward trend. In comparison with the same time last year, the total application figure has increased from 6 273 to 7 507 – a growth of 19,7%.

So far, applications for postgraduate studies are showing the biggest growth with 1 342 applications received. During the same time last year, 594 applications for postgraduate studies were received – an increase of 126%.

Prospective students have until 30 November 2008 to apply for admission. “This applies to first-time entering first-year students and senior students who have interrupted their studies for at least one year,” said Mr Vernon Collett, Registrar: Student Academic Services, at the UFS.

According to Mr Collett students whose applications for admission are received after 30 November 2008 and until 13 January 2009 will be accepted subject to the availability of place on the programme they applied for.

Applications from prospective students who wrote the Senior Certificate (prior to 2008) and who are in the possession of a conditional exemption will only be accepted until 5 January 2009.

Prospective students who want to apply must pay a non-refundable fee of R140.
The signed application form must be accompanied by a certified copy of the prospective student’s identity document or passport, a proof of payment of the application fee as well as a certified copy of their Statement of Results of their Senior Certificate.

Prospective students who are in Grade 12 this year will receive a National Senior Certificate. A certified copy of their Statement of Results must be faxed to the UFS not later than 7 January 2009.

The application form of a minor must be signed by his/her parent or guardian and the field of study should be clearly indicated.

First-time entering first-year students from the Faculties of Economic and Management Sciences and the Humanities (including Education) will be welcomed by the Acting Rector, Prof. Teuns Verschoor, on Friday, 9 January 2009 at 09:00 in the Callie Human Centre on the Main Campus.

The welcoming of students from the Faculties of Health Sciences, Natural and Agricultural Sciences, Law and Theology will take place on Saturday, 10 January 2009 at 09:00 in the Callie Human Centre.

The registration of first-time entering first-year students will commence on 13 January 2009 and that of senior students on 19 January 2009 at the Callie Human Centre according to a programme.

Students who applied for admission after 30 November 2008 and are accepted can register from 4 February 2009.

Lectures will commence on 2 February 2009 and the registration process will end on 10 February 2009. This is applicable to all students – undergraduate as well as postgraduates

Prospective students who want to apply for admission or who have any enquiries can call 051 401 3000 or visit the UFS web site at www.ufs.ac.za.
