London, Feb 25 : Obese teenagers run the same risk of premature death in adulthood as people who smoke more than 10 cigarettes a day, according to a new study.
The British Medical Journal study also found that people who are overweight have the same risk as less heavy smokers.
To reach the conclusion, Dr Martin Neovius at Karolinska Institute in Sweden, analysed the cause of death of over 45,000 men who underwent mandatory military conscription tests in Sweden.
All participants had their body mass index (BMI) measured and reported their smoking status at the age of 18 and were tracked down for an average of 38 years.
