Research unit contributes to global study

RESEARCHERS: The three researchers formed part of global study recently published in The Lancet RESEARCHERS: The three researchers formed part of global study recently published in The Lancet

Two Adjunct professors with the SA Medical Research Council/CPUT Cardiometabolic Health Research unit and one of its collaborators are amongst the researchers of a recently released global study published in The Lancet, which showed that more than one billion people in the world are now living with obesity.

Adjunct Prof Tandi E Matsha, founder and co-director of the unit and former Dean of the Faculty of Health and Wellness Sciences, Adjunct Prof Rajiv T Erasmus and Prof Andre Pascal Kengne, Director of the intermural SAMRC Noncommunicable Disease unit and a collaborator of the SAMRC/CPUT Cardiometabolic Health Research Unit are among the approximately 1500 researchers of the study titled Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults.

Researchers analysed weight and height measurements from over 220 million people aged five years or older, representing more than 190 countries.

According to a press release the analysis of global data estimates that among the world’s children and adolescents, the rate of obesity in 2022 was four times the rate in 1990. Among adults, the obesity rate more than doubled in women and nearly tripled in men. In total, 59 million children and adolescents and 879 million adults were living with obesity in 2022.

Between 1990 and 2022, the proportion of the world’s children and adolescents who were affected by underweight fell by around one fifth in girls and more than one third in boys. The proportion of the world’s adults who were affected by underweight more than halved over the same period.

Prof Glenda Davison, Head of the Department of Biomedical Sciences and Interim SARChi chair in cardiometabolic health, said she was proud to work with all three scientists.

“This type of collaboration, with world leaders, is a great achievement. The Lancet is a very high impact journal and is recognised as one of the premier journals in medical and health Science. What a fantastic achievement for our unit and for CPUT.”

*The study was conducted by the NCD Risk Factor Collaboration (NCD-RisC), in collaboration with the World Health Organization (WHO).
