The largest endeavors to improve health across Europe is the World Health Organization European Region. The goal is to improve the health of poor and disadvantaged populations by promoting healthy lifestyles including environmental, economic, social and providing health care. Overall health in Europe is very high compared to the rest of the world. The average life expectancy is around 78 in EU countries but there is a wide gap between Western and Eastern Europe. It is as low as 67 in Russia and 73 in the Balkan states. Europe is seeing an increase in the spread of HIV/AIDS in Eastern Europe because of a worsening socioeconomic situation. Cardiovascular disease, cancer and diabetes mellitus are more prevalent is Eastern Europe. The WHO claims that poverty is the most important factor bringing on ill health across Europe. Those at low socioeconomic status levels and many young people are also at risk because of their increased tobacco, alcohol and drug abuse. Health and illness prevention in Europe is largely funded by the governmental services including: regulating health care, insurance and social programs. The role of religion and traditional medicine, however, is often left unexamined in such reports.
