Globally, increased blood pressure is the leading cause of deaths and disability. An estimated 18% of deaths (9.4 million) and 162 million years of life lost were attributed to increased blood pressure in 2010. One half of blood pressure related disease occurs in people with higher levels of blood pressure even within the normal range. Hypertension now disproportionately impacts low and middle-income countries.
High dietary salt is one of the major global health risks estimated to have caused over 3 million premature deaths, 61 million years of disability (DALYs) and 57 million years of life lost in 2010. Over 300 million people are estimated to have hypertension caused by high dietary salt. Apart from hypertension, high salt intake is associated with gastric cancer, recurrent kidney stones, osteoporosis, obesity, and kidney, heart and blood vessel damage. Adults should eat less than 5 g of salt (2000 mg sodium) a day. The WHO has indicated reducing dietary salt is a best way to to improve health.
The WHD was first inaugurated in May 2005 and has become an annual event ever since. The purpose of the WHD is to promote public awareness of hypertension and to encourage citizens of all countries to prevent and control this silent killer, the modern epidemic.
