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.

The right attitude, a special group of players, and pride to represent their residence. According to Stephen Botha, Vishuis rugby captain, these were the ingredients for his team’s Varsity Cup success as they claimed a fifth national title.

The residence on the Bloemfontein Campus of the University of the Free State (UFS) was crowned Koshuis Champions of the Varsity Cup for a second consecutive year. In a repeat of last year’s final, they beat Patria from Pukke (25-10) on 17 April 2017 in Pretoria.
    
University continues national supremacy
Abraham Fischer not only staked its claim again as the most successful residence rugby team in South Africa, but also continued the supremacy of the UFS. The university has been national champions seven out of the ten years of the tournament. Armentum and Legatum were also champions.

“I always say that whoever wins the final of the residence league here, will probably win the Varsity Cup,” Botha says.

Team prepared for finals rugby
He attributes the success to his team’s positive attitude. “Even when we were doing fitness, the guys never complained and never asked how much more we have to do. They just did it."

“I always say that whoever
wins the final of the residence
league here, will probably win
the Varsity Cup,” Botha says.

Vishuis never seemed under too much pressure in the final. Their forwards laid a solid foundation, having the upper hand in the scrums, line-outs, and driving mauls. Although Vishuis is renowned for running rugby, Botha says his team prepared for finals rugby. “We decided to stick to the basics and not to play too risky.”

However, they lost their last league match against Sonop from Tukkies (21-23). Botha agrees that it might have been the right thing before the final. “Like I always say: ‘Every setback is a set up for a great comeback’”.

•    Vishuis centre Wian van der Watt was chosen as the Koshuis Player of the Tournament, while two Shimla flankers, Daniel Maartens and Phumzile Maqondwana, were included in the Varsity Cup Dream Team.
