New research predicts a rise in life expectancy worldwide over the next three decades, particularly in Africa. Meanwhile, obesity and other factors are also set to play a larger role in poor health.

Global life expectancy is set to increase by almost five years by 2025, new research has found, but factors like obesity and high blood pressure mean people will spend more years in poor health.

The findings were part of the Global Burden of Diseases, Injuries and Risk Factors Study 2021, which was published in the medical journal *The Lancet *on Thursday.

“Future trends may be quite different than past trends because of factors such as climate change and increasing obesity and addiction,” said Liane Ong, lead research scientist at the Institute for Health Metrics and Evaluation (IHMEE) at the University of Washington, which led the study.
