Prof Atangana — Prof Abdon Atangana, a professor of Applied Mathematics at the University of the Free State (UFS), is the highest-ranked UFS scientist included in Stanford University’s World’s Top 2% Scientists list.

A professor of Applied Mathematics at the University of the Free State (UFS) is again the highest-ranked scientist from the institution included in Stanford University’s annual ranking of the top 2% of scientists in the world.

Prof Abdon Atangana from the UFS’s Institute for Groundwater is ranked number one in applied mathematics, mathematical physics, mathematics, and statistics in the world, and number 260 in all of science, technology, and engineering in the Stanford University World’s Top 2% Scientists list. He is also ranked highest (5 620) of all the UFS scientists included in the career-long data set.

‘Africans in Africa can impact the world’

“The ranking provides us with the impact of our outputs, and it shows that Africans can contribute to the development of science, technology, engineering, and mathematics while still in Africa,” Prof Atangana said. “This also shows that Africans in Africa can have impact on the world. My motivation is to tell the next generation that Africans do not always need to graduate from the top universities of the global North to make a global impact.

“We must work hard to make our African universities reach the same level of those from the global North, such that a student from the global North will wish to enroll in our universities. The development of our continent does not rest on sport, music, and so forth alone, but on science, technology, engineering, and mathematics. Having the best scientists, mathematicians, and engineers in the world in Africa should be the strive of all Africans.”

Three of the UFS’s SARChI Research Chairs have also been included in this list: Prof Hendrik Swart, Chair: Solid-state Luminescent and Advanced Materials (Applied Physics, ranked 40 269 in the single-year dataset); Prof Melanie Walker, Chair: Higher Education and Human Development (ranked 68 337); and Prof Maryke Labuschagne, Chair: Disease Resistance and Quality in Field Crops (Plant Sciences, 165 780).

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.

Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.

Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.

Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.

Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.

The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.

A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.

The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.

When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.

Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.

At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.

The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
