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 tightens links with Netherlands’ Dronten University
2007-08-10

 

The University of the Free State (UFS) and CAH Dronten Professional Agricultural University, the Netherlands are expanding and strengthening the relationship between the two institutions. The focus of the cooperation will initially be within the Departments of Agricultural Economics and Animal, Wildlife and Grassland Sciences.

Prof. Herman van Schalkwyk, Dean of the Faculty of Natural and Agricultural Sciences, visited Dronten recently to investigate the possibility and feasibility of a more formal linkage between the two institutions. That was followed by a visit from Dr Will Beckering to the UFS where a letter of undertaking was signed, paving the way for the establishment of a memorandum of understanding and implementation agreements.

Both the institutions share an interest in the training of emerging farmers; the carrying out of an agricultural skills development project; short-term visits of staff for consultations and lecturing; formulating and implementing projects on capacity development to broaden access to professional education; exchange of students for study programmes, placement projects; curricular development, more especially the possibilities of developing a joint master’s degree programme; and identifying the possibilities of the use of e-learning in joint educational programmes.
