World caught in "syndemic" of chronic diseases and Covid-19, global study says
The world is caught in a perfect storm of rising rates of chronic disease, persistent infectious diseases and public health failures that have fuelled deaths in the Covid-19 pandemic, according to a major global study of human health.
The emergence and overlap of the coronavirus pandemic with a continued global rise in chronic conditions such as obesity and diabetes - with added environmental risks such as air pollution - have exacerbated the coronavirus death toll, it said.
The Global Burden of Disease (GBD) study is the most comprehensive of its kind.
Published in The Lancet medical journal, it analysed 286 causes of death, 369 diseases and injuries and 87 risk factors in 204 countries and territories to offer a view on the underlying health of the global population and the impact of Covid-19.
"Covid-19 is an acute-on-chronic health emergency," said Richard Horton, the Lancet's editor-in-chief.
He described the coronavirus pandemic combined with high global rates of obesity, diabetes and other chronic diseases as a "syndemic".
The study found that leading causes of ill health in people aged 50 and older worldwide were ischaemic heart disease, stroke, and diabetes.
In younger people - aged 10 to 49 - road injuries, HIV/AIDS, lower back pain and depressive disorders were dominant.
