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.

Community service must heal our campus

Community service and community service learning at the University of the Free State must be put in the forefront of healing our divided campus and our divided country.
This was the message from the Acting Rector Prof Teuns Verschoor when he opened the Community Service Summit that was held in Thaba Nchu on 9 and 10 October 2008.
“The importance of community service is that it heals those who help others because the needs of others are more important than our own needs when we render service to those who are worse off than ourselves,” prof Teuns said.

He said community service has already helped to change the UFS in terms of the academic experience of students and staff and in terms of the perceptions that various communities hold about the UFS.

The summit was attended by more than 35 representatives from different Faculties and departments of the university, representatives from the communities in the Motheo and Xhariep District Municipalities as well as the project managers of Lebone Land and the Bloemfontein Life Change Centre.

Several issues pertaining to the Community Service Policy of the UFS, as well as other related issues were discussed which will culminate in a Statement of Intent that will be handed to the Executive Management of the UFS. This is being done in response to the challenge of the acting rector that the Summit will make a meaningful input in the repositioning process of the UFS.

One delegate described her participation in the Summit as a life changing experience. “This articulation of her experience has captured the views of a lot of the delegates. It shows that there is a big need to cement the importance, commitment to and implementation of Community Service and Community Service Learning at the University of the Free State. With the support of our partners we are determined to make a difference in the lives of the people of the Free State and beyond,” said Rev Kiepie Jaftha, Chief Director Community Service at the university.
