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.

Africa and her diaspora grace the Africa Century International Writers’ Conference

2012-10-30

30 October 2012

Programme (Pdf format)

The Africa Century International African Writers’ Conference, organised by the wRite associates, in partnership with the Department of Arts and Culture, the University of the Free State (UFS) and the SABC, will take place on the Bloemfontein Campus of the UFS from 7 to 10 November 2012.This four-day conference will culminate in the 2012 South African Literary Awards ceremony where winners will be honoured.

The conference is dedicated to the memory and contribution of its special advisor and inspiration, Zwelakhe Sisulu, who passed away in October 2012.

The conference has attracted an array of scholars and artists from around the continent. The African diaspora will be one of the main features of the programme. Keynote addresses, the presentation of papers, dance, visual art, comedy, disc jockeying will all feature the Diaspora.

“This event will also mark the 21st anniversary of the then-OAU (now-AU) declared International African Writers’ Day (i.e. 7th November). The theme of this is: From Resistance to Creative Mediation: Celebrating a Century of Writing and Literary Intellectuals’ Influence On The Liberation Struggles & Political Impact on Literary Discourse and Development”, said Raks Morakabe Seakhoa, Managing Director of the wRite associates and Project Director of the South African Literary Awards and the Africa Century International African Writers Conference.

The patrons of the Africa Century International African Writers’ Conference include; Prof. Kgositsile Keorapetse, Prof. Chinua Achebe, Dr Nadine Gordimer, DrWanguiwaGoro and Dr Hugh Masekela.

“This prospective historical gathering of authors, literary scholars and historians will, as the then-OAU’s Conference of African Ministers of Education and Culture (meeting in Coutonou, Benin, in 1991) resolved, ‘…afford the African people a moment of pause within which to reflect on the contribution of African Writers to the development of the Continent’ ”,Seakhoa added.

He said, “We are delighted at the growth of the prestigious South African Literary Awards, as they are now spreading their wings to inaugurate the Africa Century International African Writers’ Conference and opening up to the continent and Diaspora’s writers.”

Other highlights of this four-day programme include:

An evening with the National Poet Laureate: poetry reading by Prof. Keorapetse Kgositsile and guest poets
Nobel Laureate, Nadine Gordimer discusses her latest work, ‘No Time Like The Present’
Poetry, comedy and performances
Creative writing skills development programme, facilitated by: Prof.KeorapetseKgositsile, Mr Walter Chakela and Dr Oswald Mtshali
Tsebo-Lethabo Primary and High Schools programme
Books, art & crafts and clothing exhibitions and more
