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.

Food insecurity at university campuses under the spotlight
2015-08-20

 

"Food insecurity is   becoming an increasing problem at South African universities, much to the surprise of university managers." - Dr Louise van den Bergh, senior lecturer and researcher at our department of Nutrition and Dietetics

More than 70% of early university dropouts in the country were forced to abandon their tertiary studies because of food insecurity and financial need.

This was one of the conclusions drawn during the first higher education colloquium on food insecurity. The colloquium was hosted on by the University of the Free State (UFS) on the Bloemfontein Campus on 14 August 2015, where researchers from universities across the country shared their research about food insecurity on university campuses.

In South Africa, university campuses are not usually associated with food insecurity but, over the last few years, tertiary education has become more accessible to an increasing number of first-generation students and students from low-income households.

Some of the research indicated that students from lower-income households are often lacking financially, even with bursaries. The research has also shown that students frequently have to use part of their bursary money to support their families. This results in students not having enough money to buy food, which means they will do almost anything to get food.

A study by the UFS Department of Nutrition and Dietetics found that as many as 60% of our students are food insecure, and experience hunger frequently. This study was the first of its kind in South Africa. In 2011, the UFS launched the No Student Hungry Bursary Programme to provide food bursaries to food-insecure students.

At the opening of the colloquium, Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said by helping students with a basic commodity like food, you give them much more than food; you give them humanity and dignity.

Dr Louise van den Bergh, senior lecturer and researcher in the UFS Department of Nutrition and Dietetics, explains that the problem is considerably more complex than just providing for students financially.

Dr Van den Bergh says that funders need to reassess bursaries, keeping issues such as food insecurity in mind, and not focusing just on tuition.
