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.

Fundraising campaign launched to help feed hungry students

The University of the Free State (UFS) received over R200 000 for its No Student Hungry (NSH) Programme at the NSH launch dinner on Friday 23 March 2012 in Bloemfontein.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS as well as founder of the NSH Programme donated R100 000 from the proceeds of his book We Need to Talk to this programme. Standard Bank also donated R30 000.

An additional amount of about R90 000 was raised by means of pledges made by guests and the auctioning of several items. These items were donated by local companies and university staff.

The No Student Hungry Programme (NSH) aims to raise funds to provide modest food bursaries for needy students and give them daily access to a balanced meal.
Prof. Jansen started the NSH programme in 2011 with the proceeds of his book, We Need to Talk.

The NSH funds more than 100 students in the hope of helping them to excel in their academic endeavours and, ultimately, to obtain their degrees.

In 2011, Prof. Jansen discovered that a significant number of students were studying without eating on a regular basis. These were often students with strong academic records but without adequate funding to sustain themselves with regular meals.

The project was established in January 2011 when the NSH Team started to develop the structure and processes of the programme. The first 100 students who were awarded the food bursaries started using their student cards for daily meals on campus on 1 April 2011.

“The No Student Hungry Campaign is not only about creating a university campus that cares. It is about creating a country where being human matters. Our students on the NSH project are amazing young people. They struggle to get by, but they have great potential and achieve good marks," Prof. Jansen said on Friday.

Prof. Jansen’s wife, Grace, and Dr Carin Buys, wife of Mr Rudi Buys, Dean of Student Affairs, volunteered to drive the programme and raise funds to address the problem. They are supported by various divisions within the university.

Students apply for the bursaries and are selected on the basis of their financial needs, good academic results, active participation in student life programmes and commitment to give something back to the community.

The raising of funds is a continuous process involving awareness campaigns, seeking of partnerships with companies and institutions and support from the general public, staff and individuals.

An agreement has been made with several food outlets/restaurants on campus who offer healthy, balanced meals to NSH students when they swipe their student cards that are funded by the programme.

At the end of the year the process is reviewed and students who still qualify are reinstated on the programme, whilst those whose circumstances have changed or are no longer in need of the bursaries, make way for new applications.

The NSH Team meets with students on a regular basis with the purpose of offering training, motivation and opportunities for personal growth and career development. Students are also expected to become involved in projects as a way of ploughing back into the community.

The goal is to expand the project annually as support for it grows.
Ms Nicky Abdinor, a clinical psychologist from Cape Town, who was born without arms and with shortened legs, provided an entertaining motivational speech at the launch. Ms Abdinor, founder of the Nicky's Drive organisation, also visited the UFS’ Unit for Students with disabilities where she delivered a talk on independence for people living with disabilities.
