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 Sasol Library will reopen tomorrow
2007-10-17

The University of the Free State’s (UFS) UFS Sasol Library will reopen again tomorrow (Thursday, 18 October 2007) after a limited fire broke out earlier this morning.

The fire broke out at 05:00 on a work site of a contractor that is carrying out maintenance on the library’s air conditioning system in the machinery room underneath the library.

Employees of the subcontractor were busy replacing the isolation of the air-conditioning when the fire broke out. An employee of the contractor died and one was seriously injured.

The contractor is working on the system at night in order to minimise disruption to library users. The building and books were not damaged.

“The UFS and the contractor exercised strict safety measures before the maintenance project commenced and regular safety training sessions are still presented to employees of the contractor working on the site. The latest training session was done on Monday, 15 October 2007,” said Ms Edma Pelzer, Director of Physical Resources at the UFS.

As a precautionary measure, the library will be closed for the rest of today because of the possible presence of fumes in the building as a result of the fire. A decision was taken to be cautious and to make sure that the air is clean before people are allowed in the library.

The Reitz Dining Hall of the Centenary Complex is available as a temporary study facility for students until 18:00 today. The library will be open again tomorrow (Thursday, 18 October 2007) during normal hours.

Ms Pelzer conveyed her sympathy to the next of kin of the person who died during the fire.
