, Denmark has a life expectancy of 80.6 years at birth (78.6 for men, 82.5 for women), up from 76.9 years in 2000. This ranks it 27th among 193 nations, behind the other Nordic countries. The ''National Institute of Public Health'' of the University of Southern Denmark has calculated 19 major risk factors among Danes that contribute to a lowering of the life expectancy; this includes smoking, alcohol, drug abuse and physical inactivity. Although the obesity rate is lower than in North America and most other European countries, the large number of Danes becoming overweight is an increasing problem and results in an annual additional consumption in the health care system of DKK 1,625 million. In a 2012 study, Denmark had the highest cancer rate of all countries listed by the World Cancer Research Fund International; researchers suggest the reasons are better reporting, but also lifestyle factors like heavy alcohol consumption, smoking and physical inactivity.
