In recent decades, advances in technology and medicine have increased the life expectancy and general health of people around the world. However, great inequalities in health and health care based on geography and wealth still exist. For example, all of the twenty countries with the lowest life expectancy in 2017 were located in Africa, while those with the highest life expectancy were found mostly in Europe and the wealthy countries of Asia. Rates of various diseases also differ depending on region and income, but some of the most common negative health conditions around the world include high blood pressure, sleep related conditions, migraines, and high cholesterol.
According to the most recent figures, the United States spends the highest percentage of its GDP on health among OECD countries. Health spending per capita in the U.S. amounted to around 9,800 U.S. dollars in 2016, compared to 5,450 dollars in Germany and 4,720 dollars in Canada. The United States is also the country that spends the most on diabetes health expenditure, by a large margin. Although obesity is a growing problem in many countries, the United States still reports the highest rates around the globe. However, rates of other common health risks are much higher in other countries. For example, the smoking population of men is highest in Indonesia and China, while Moldova and Lithuania are the countries with the highest per capita alcohol consumption.
