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 Prestige Scholar shares her vision on crystallography with worldwide audience
2014-04-24

 
Dr Alice Brink
Dr Alice Brink, a Prestige Scholar and lecturer in the Department of Chemistry at the University of the Free State, was selected by UNESCO to participate, together with some 15 other young scientists from all over the world, in a round-table discussion at the Opening Ceremony of the International Year of Crystallography.

During this event, that took place in Paris, France, Dr Brink could, on stage, share her vision as one of the next generation of scientists.

“The 15 crystallographers consisted of eight young, established scientists and seven ‘young-young’ scientists who are starting their careers. We participated in a group discussion in order for the crystallographic community to better understand the challenges faced by young scientists across the globe.

“It was a great privilege to be invited to be part of this talented and diverse discussion group and to hear the challenges that are faced by young scientists from different parts of the world. It is also comforting to hear that scientific difficulties that are found in South Africa are commonly experienced in both First and Third World countries,” said Dr Brink.

“Crystallography has directly influenced the development of numerous scientific fields such as chemistry, physics, mathematics, medicine, engineering and material sciences. More inter-departmental collaboration would benefit greatly from crystallography, as this multi-faceted science provides foundation principles for applied research,” she said.

The United Nations declared 2014 as the International Year of Crystallography, and it was officially opened at the UNESCO Headquarters in Paris by the Secretary-General of the UN, Ban Ki-moon.

The ceremony was video-streamed live to more than 500 destinations all over the world.
