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.

UFS DiMTEC will help compile national emergency management system

Preparedness and response are the two most important aspects of managing disaster when it strikes. Prof Andries Jordaan, Head of the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS) recently attended an incident command course in California in the US.

Learning from US disaster management systems
More than 20 specialists from 17 countries attended the course where participants were introduced to the National Incident Management System (NIMS) in the US. The system was implemented after lessons learned during 9/11. “According to the NIMS structure, all government organisations at all levels as well as emergency agencies had to standardise terminology and systems,” said Prof Jordaan.

The professor also had the opportunity to visit among others the Federal Emergency Management (FEMA) headquarters in California, some State Coordination Centres as well as several other disaster management centres. He also had the chance to shadow an Incident Management Team (IMT) during active operations.

Providing training for local disaster management
Insight gained during this course, as well as Prof Jordaan’s experience as senior officer in the South African National Defence Reserve Forces, provided him the necessary background to conduct training and give assistance in terms of disaster management.

Through DiMTEC Prof Jordaan will assist the National Disaster Management Centre with the implementation of a national emergency management system. He will also provide training for incident management teams.

“DiMTEC is currently also in the process of developing a Master module in disaster response. Command and control and Incident Command will form a sub-module in the disaster response module,” he said.

From South Africa, Prof Jordaan was joined on the course by General Elias Mpumelelo Mahlabane from the South African Police Services, who is responsible for disaster management in the SAPS. Savage Breytenbach, a trainer in rural fire fighting who assists Mangaung with command and control structures, also attended the course.
