(TELEGRAPH) — People living in the tropics are likely to die more than seven years younger than those in other regions, according to the first findings of a new global research project.

The “State of the Tropics” study, run by 13 institutions across 12 countries, reported that people living in the world’s tropical zones in 2010 had an average life expectancy of 64.4 years.

This was 7.7 years less than those living in non-tropical areas, according to the broad-ranging research project, which was initiated by Australia’s James Cook University (JCU).
