One in five adults and one in 10 children and teenagers are projected to be obese by December 2023 in 10 high-burden African countries if no robust measures are taken to reverse the trends, a new World Health Organization (WHO) analysis shows.
The WHO analysis finds that the prevalence of obesity among adults in the 10 high-burden countries will range from 13.6% to 31%, while in children and adolescents it will range from 5% to 16.5%. Africa also faces a growing problem of overweight in children. In 2019, the continent was home to 24% of the world’s overweight children aged under 5.
Being overweight has been associated with severe disease and the need for hospitalization with COVID-19.
Being obese or overweight raises the risk of suffering cardiovascular diseases, diabetes, muscle and skeletal disorders as well some types of cancer. Among children, being overweight is associated with a higher chance of obesity, premature death and disability in adulthood.
While no data is available yet for Africa, a study published by the Journal of Infection and Public Health found that of the 2.5 million COVID-19 deaths reported globally by the end of February 2021, 2.2 million were in countries where more than half the population is classified as overweight.
World Obesity Day, which will be marked on 4 March, has the theme “Everybody Needs to Act”.
“Africa is facing a growing problem of obesity and overweight, and the trends are rising. This is a ticking time bomb. If unchecked, millions of people, including children, risk living shorter lives under the burden of poor health,” said Dr Matshidiso Moeti, WHO Regional Director for Africa.
She added, “But we can resolve the crisis, because many of the causes of obesity and overweight are preventable and reversible.”
To combat obesity and overweight, WHO recommends a range of priority measures including government regulations such as mandatory limits on food sugar content; fiscal policies, for example, taxing sugar-sweetened beverages; food marketing regulations such as obligatory nutrient declaration by manufacturers; promoting healthier foods for older infants and young children; creating facilities for safe, active transport and recreation as well as reinforcing public health services.
Lowering the risk of overweight and obesity includes adopting a healthy diet such as reducing the number of calories consumed in fats and sugars, undertaking regular physical activity as well as government policies that help people opt for healthier lifestyles and diets, for instance, by ensuring that healthy foods are accessible and affordable.
