Infant body composition research revolutionised with new PEA POD® technology

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 Council adopts guidelines for the development of a new Language Policy

2015-12-04

The Council of the University of the Free State (UFS) adopted the following guidelines from the report by the Language Committee regarding the development of a new Language Policy for the UFS, based on the core values of inclusivity and multilingualism:

that English becomes the primary medium of instruction in undergraduate education and, as largely exists already, in postgraduate education.
that the UFS embeds and enables a language-rich environment committed to multilingualism, with particular attention to Afrikaans, Sesotho, isiZulu, and other languages represented on the three campuses.
that an expanded tutorial system be available to especially first-year students in Afrikaans, Sesotho, isiZulu and other languages, in order to facilitate the transition to English instruction.
that the parallel-medium policy continues in particular professional programmes, given the well-defined Afrikaans markets that, at the moment, still makes such language-specific graduate preparation relevant.
that the language of administration be English.
that the English-medium language policy be implemented with flexibility and understanding, rather than as a rigid rule disregarding the circumstances.

These guidelines were adopted at the Council meeting which took place on the Bloemfontein Campus on Friday 4 December 2015.

“This important and emotive matter was discussed in a high-quality, open debate and I am satisfied with the way the decision was reached,” says Judge Ian van der Merwe, Chairperson of the UFS Council.

The decision by Council comes after a mandate was given to the University Management on 4 June 2015 to conduct a review of the institutional Language Policy. A Language Committee was subsequently established by the University Management Committee (UMC) to undertake a comprehensive review of the existing parallel-medium policy and to make recommendations on the way forward with respect to the university's Language Policy.

The Language Committee conducted a comprehensive consultation process on the future of the Language Policy with all university stakeholders. This included multiple dialogue and submissions sessions, as well as an opinion poll on all three campuses.

Guided by the Council resolution of 4 December 2015, the UFS management will now proceed to design a Language Policy that would be presented to the UMC and Senate for voting purposes again, which vote would be formally presented to Council at one of its governance meetings in 2016. The Institutional Forum, a statutory body that represents all university stakeholders, would also advise Council at that stage, per its mandate, on the new Language Policy.

In the event that a new Language Policy is accepted by Council in 2016, the earliest possible date for implementation would be January 2017.
