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.

Twee broers lewer intreerede
2004-06-10

‘n Unieke geleentheid sal homself môre, 9 Junie 2004, voordoen wanneer twee broers - proff Francois en Janse Tolmie - tydens dieselfde geleentheid hul intreeredes aan die Universiteit van die Vrystaat (UV) sal lewer.

Prof Francois Tolmie is verbonde aan die UV se Departement Nuwe Testament en die onderwerp van sy lesing is Die impak van die metodologie op die verstaan van die Nuwe Testament. Prof Janse Tolmie, sy jonger broer, is verbonde aan die UV se Departement Rekenaarwetenskap en Informatika en die onderwerp van sy lesing is Die rol van inligtingstegnologie in kennisbestuur.

Hoewel die studievelde vér verwyderd staan, klop die twee broers se missies wat betref die terugploeg van die verworwe vakkennis ten bate van die gemeenskap. Prof Francois Tolmie is nóú betrokke by dowes en Prof Janse Tolmie tap weer kunsmatige intelligensie ten bate van die mediese wetenskap en geestesgesondheid.

Prof Francois Tolmie verwerf die grade BA, BA Honneurs (Grieks), MA (Grieks), B Th en M Th almal cum laude aan die UV. In 1992 verwerf hy 'n D Th (Nuwe Testament) en in 2004 'n Ph D (Grieks) aan dieselfde universiteit. Na sy militêre diens as kapelaan in Walvisbaai aanvaar hy 'n beroep na die NG-gemeente Walvisbaai. Hy begin sy akademiese loopbaan op 1 April 1990 as senior lektor in die Departement Nuwe Testament en word in 1999 tot medeprofessor en in 2003 tot professor bevorder.

Sy navorsingspesialiteit is die Johannesevangelie en die Brief aan die Galasiërs. Hy is tesourier van die Nuwe Testamentiese Werksgemeenskap van Suid-Afrika, lid van die Society of Biblical Literature en die Studiorum Novi Testamenti Societas, redakteur van Acta Theologica en assistent-redakteur van Neotestamentica. Hy het reeds 34 artikels in geakkrediteerde tydskrifte gepubliseer, asook drie populêr-wetenskaplike boeke en talle bydraes in populêr-wetenskaplike boeke. Hy het twee akademiese boeke in die buiteland gepubliseer - onderskeidelik in Nederland en in die VSA. Later vanjaar verskyn 'n derde akademiese boek in Duitsland. Hy is ook een van die vertalers van die Afrikaanse Bybel vir Dowes.

Prof Janse Tolmie verwerf die grade B Sc, B Sc (Hons) en M Sc (Cum Laude) in Rekenaarwetenskap aan die UV.

Hy is vanaf 1989 betrokke by die UV en was ook ’n dosent aan die Militêre Akademie in Saldanhabaai in 1990/91 en het klas gegee by DePaul Universiteit in Chicago in 2002.

In 1992 is hy vir ses maande gesekondeer na ’n patologiese firma, Van Drimmelen en Vennote, in Johannesburg vir die ontwikkeling van kennisgebaseerde sagteware. Met hierdie projek word hy een van slegs ’n handjievol navorsers in die wêreld wat daarin kon slaag om ’n mediese kundigheidstelsel te ontwikkel wat werklik gebruik word.

Hy verwerf sy Ph D in 1994 en in 1994/95 doen hy navorsing aan die Besigheidskool van Carleton Universiteit in Ottawa, Kanada. Hy word in 1997 bevorder tot mede-professor en in 2003 tot volprofessor. Vanaf 2003 tree hy op as departementele voorsitter van die UV se Departement Rekenaarwetenskap en Informatika.

Hy het meer as 30 publikasies al die lig laat sien, insluitend verskeie internasionale kongresbydraes en artikels in geakkrediteerde joernale. Hy was ook vir 2 siklusse geëvalueer by die NRF. Sy portfolio sluit in die ontwikkeling van sagteware of prototipes vir groot maatskappye soos Van Drimmelen en Vennote en Bayer Diagnostics (VSA). Sy privaatbesigheid fokus op die ontwikkeling van nismarksagteware vir tersiêre instellings. Die sagteware word tans gebruik deur afdelings aan verskeie universiteite in Suid-Afrika.

Die geleentheid vind om 19:00 in die CR Swart-ouditorium op die kampus plaas.
