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.

Researcher in Otorhinolaryngology advocates education in deafness and hearing loss

The annual International Day of Persons with Disabilities falls on 3 December. Statistics reveal that 7.5% of the South African population suffer from some form of physical disability.

More than 17 million people in South Africa are dealing with depression, substance abuse, anxiety, bipolar disorder, and schizophrenia - illnesses that round out the top five mental health diagnoses, according to the Mental Health Federation of South Africa. The South African Federation for Mental Health is the umbrella body for 17 mental health societies and numerous member organisations throughout the country.

On disability, world-renowned author Helen Keller, who was both deaf and blind, once said that the problems that come with being deaf are deeper and more complex than those of blindness, and is a much worse misfortune. For it means the loss of the most vital stimulus - the sound of the voice that brings language, sets thoughts astir, and keeps us in the intellectual company of man.

According to Dr Magteld Smith, lecturer and researcher in the Department of Otorhinolaryngology at the University of the Free State (UFS), hearing loss of any degree at any age can have far-reaching psychological and sociological implications which affect an individual’s day-to-day functioning, and might prevent him or her from reaching their full potential. She says that even though advancements have been made in aiding deaf persons, there’s still considerable room for improvement. She’s making it her mission to bring about changing the stigmatisation around deafness, and the different choices of rehabilitation.

Dr Smith was born with bilateral (both ears) severe hearing loss, and became profoundly deaf, receiving a cochlear implant in 2008. Not letting this hinder her quality of life, she matriculated in 1985 at a School for the Deaf in Worcester. Today she is the only deaf medical-social researcher in South Africa.

Her research focuses on all aspects of deafness and hearing loss. Through first-hand experience, she knows that a loss of hearing can be traumatic as it requires adjustments in many areas of life which affect a person’s entire development. However, she has not let her deafness become a stumbling block. She has become the first deaf South African to obtain two Master’s degrees and a PhD, together with various other achievements.

Her work is aimed at informing and educating people in the medical profession, parents with children, and persons with various degrees and types of hearing loss about the complexities of deafness and hearing loss. She believes that, with the technological advancements that have been made in the world, deaf people can become self-sufficient and independent world changers with much to contribute to humanity.
