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.

Qwaqwa Campus kicked off the 2017 graduations season of the University of the Free State in style when over 550 degrees and certificates were conferred in three sessions on 12 and 13 May 2017. These included five PhDs from the Faculty of Natural and Agricultural Sciences.

In his maiden speech delivered during the two ceremonies on Friday 12 May 2017, the newly-appointed Vice-Chancellor and Rector, Prof Francis Petersen, emphasised the interconnectedness of graduates with other stakeholders in their communities.

“Never forget the role played by other people who sacrificed a lot for you to be here today. Recognise the extra mile that someone was willing to go for you to graduate,” he said to an enthusiastic audience that included Grade 12 learners from neighbouring schools. 

Prof Petersen also reminded the graduates that not everybody had an opportunity to enter, enrol, and eventually graduate at a university. “You are part of the privileged few, and I am confident that the UFS has given you an equal opportunity to reach your full potential. You have had years of exposure to ideas and experiences on diversity. You now have the opportunity to show the world and to use what you have learnt beyond a classroom,” he added.

“Go out there and open doors for others as much as they were opened for you. I implore you to carry over your experiences of diversity and use them to build a better world. Go out there and build a better world, not only for yourself but for everyone in need. Expand your influence, reach out, and be accountable,” he said.

“South Africa needs your skills,
innovation, knowledge, expertise,
and creativity.”

Make your own unique contribution
The session held on Saturday 13 May 2017 saw the Principal of Motheo TVET College and Qwaqwa Campus alumnus, Dipiloane Phutsisi, having a heart to heart with the graduates from the Faculty of Education.

“Our contribution to the world as graduates will not be measured by the wealth we accumulate or the accolades we receive, but rather by the way in which we share our unique gifts with the world. And the only place to find those gifts is to look within yourself. As the class of 2017, make your own unique contribution,” she said.

“Your graduation takes place at a particularly challenging time in the history of our democracy. It happens at a time when our nation is engulfed by racial polarisation, anger, confusion about what democracy and freedom mean to us, and at a time when the pillars of morality are tested.”

“As you graduate, I wish to remind you that our country needs you more than ever before. South Africa needs your skills, innovation, knowledge, expertise, and creativity,” she said.

Three members of the current SRC were also among the graduates. They are the President, Njabulo Mwali (BSc Information Technology), Sports Affairs Officer, Ntokozo Thango (BA Sociology), and Student Development and Environmental Affairs Officer, Ntokozo Masiteng (BA Sociology).
