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 approves a new Language Policy

2016-03-11

The Council of the University of the Free State (UFS) approved a new Language Policy with an overwhelming majority during its meeting held on the Qwaqwa Campus today (11 March 2016).

In the newly approved policy, the university commits to embed and enable a language-rich environment committed to multilingualism, with particular attention to Afrikaans, Sesotho, isiZulu, and other languages represented on the three campuses situated in Bloemfontein and Qwaqwa.

Based on the core values of inclusivity and multilingualism, the following principles in the newly approved policy were approved by the Council:

English will be the primary medium of instruction at undergraduate and postgraduate level on the three campuses situated in Bloemfontein and Qwaqwa.
Multilingualism will be supported among other activities by an expanded tutorial system especially designed for first-year students.
In particular professional programmes such as teacher education and the training of students in Theology who wish to enter the ministry in traditional Afrikaans speaking churches, where there is clear market need, the parallel medium English-Afrikaans and Sesotho/Zulu continues. This arrangement must not undermine the values of inclusivity and diversity endorse by the UFS.
The primary formal language of the university administration will be English with sufficient flexibility for the eventual practice of multilingualism across the university.
Formal student life interactions would be in English, while multilingualism is encouraged in all social interactions.

“This is a major step forward for the UFS. I commend Council for their constructive and positive manner in which the discussion took place,” says Judge Ian van der Merwe, Chairperson of the UFS Council.

The university furthermore committed in the newly approved policy to:

Ensuring that language is not a barrier to equity of access, opportunity and success in academic programmes or in access to university administration.
Promoting the provision of academic literacy, especially in English, for all undergraduate students.
Ensuring that language is not used or perceived as a tool for social exclusion of staff and/or students on any of its campuses.
Promoting a pragmatic learning and administrative environment committed to and accommodative of linguistic diversity within the regional, national and international environments in which the UFS operates.
Contributing to the development of Sesotho and isiZulu as higher education language within the context of the needs of the university’s different campuses.
The continuous development of Afrikaans as an academic language.
Recognising and promoting South African Sign Language and Braille.

Today’s approval of a new policy comes after a mandate was given to the university management on 5 June 2015 by Council to conduct a review of the institutional Language Policy through a comprehensive process of consultation with all university stakeholders. A Language Committee was subsequently established by the University Management Committee (UMC) to undertake a comprehensive review of the parallel-medium policy, which was approved by Council on 6 June 2003. The committee also had to make recommendations on the way forward with respect to the university's Language Policy. During its meeting on 4 December 2015, Council adopted guidelines from the report of the Language Committee regarding the development of a new policy for the university.

The newly approved Language Policy will be phased in as from January 2017 according to an Implementation Plan.
