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.

Student receives international award in microbiology

2008-01-24

A postgraduate student at the University of the Free State (UFS) received an exceptional honour last month when he received the first prize for his presentation in the Biochemistry and Industrial Mycology session of the Asian Mycology Congress (AMC) held in Malaysia.

Desmond Ncango (24), a Ph.D. student from the Department of Microbial, Biochemical and Food Biotechnology received the first prize for his presentation on the inhibitory effects of non-steroidal anti inflammatory drugs (NSAIDs) such as aspirin on fungi.

This suggests that commonly used aspirin may be used as a cheap antifungal to combat yeast infections. Desmond also exposed novel lubricants that are used by yeasts for water-propelled movement. This may find application in nanotechnology in the lubrication of nanorobots, which are manmade miniature machines, invisible to the naked eye, which may in future be used to combat diseases such as cancer.

The conference, which was attended by more than 300 representatives from 27 countries, is a platform for mycologists (who are experts in fungi) around the world to come together and share their knowledge and research. “Many interested researchers listened to my presentation and were impressed by the novelty and scientific depth of my work,” said Desmond.

“The presentation was selected as the best because of its novelty, academic depth as well as applicability. The meticulous preparation and presentation style also contributed to the success,” said Prof. Lodewyk Kock, head of the Lipid Biotechnology Group at the department and main promoter of Desmond’s Ph.D. studies.

“I cannot really explain the feeling when my presentation was selected as the best as it was presented in a very difficult category and many senior researchers and professors also participated. I plan to use all the knowledge and skills I have learnt from Prof. Kock, who is my role model, especially to the benefit of disadvantage communities in South Africa. I want to follow an academic career at a tertiary institution when I have completed my Ph.D. studies,” said Desmond.

Desmond went to school in Botshabelo, Bloemfontein and completed his Grade 12 in 2000 with a distinction in Mathematics. He enrolled for a B.Sc. degree at the UFS, majoring in Microbiology and Physiology. After obtaining this qualification, he joined the postgraduate research group of Prof. Kock. He completed his M.Sc. degree with distinction last year and was privileged to have this research published in and on the cover of the Canadian Journal of Microbiology, a journal accredited by the Institute for Scientific Information (ISI).

He was one of six postgraduate students from the Lipid Biotechnology Group who attended the AMC conference in Malaysia. The students’ attendance was funded by the South African Fryer Oil Initiative (SAFOI), which is housed in the UFS Department of Microbial, Biochemical and Food Biotechnology. This initiative, steered by Prof. Kock, currently monitors edible oils in the food industry in South Africa and makes a quality seal available to the manufacturers and distributors of these edible oils.

“SAFOI’s income is used to fund my own research on various kinds of oils (including yeast oils) to enable postgraduate students to attend international congresses and to partially fund international scientific symposia and congresses,” said Prof. Kock.
