Researchers at Columbia University’s Mailman School of Public Health and City University of New York have found that people who travel for business two weeks or more a month experience more symptoms of anxiety, depression and issues with sleeping than those who travel one to six nights a month. 

“Although business travel can be seen as a job benefit, there is a growing literature showing that extensive business travel is associated with risk of chronic diseases,” said Andrew Rundle, Associate Professor of Epidemiology at the Mailman School of Public Health.

Obesity linked to gene mutations

A new study, led by Imperial College London, has identified mutations in a gene related to obesity. This study could open new treatment possibilities in the fight against obesity. 

Published in Nature Genetics, the study focused on children suffering from obesity in Pakistan, where genetic links to obesity had been previously identified by the team in about 30 per cent of cases.

Just one cigarette can lead to addiction

A new study of 215,000 residents in the UK, Australia and New Zealand has found that two-thirds of those that try just one cigarette will later become addicted. The findings, which were published in the journal Nicotine & Tobacco Research, discovered that 60.3 per cent of people had tried cigarettes and of those 68.9 per cent went on to develop a smoking addiction.

The study’s authors believe that this is the first time that such a large study has been carried out regarding the effect of smoking just one cigarette.
