A new study from the American journal Health Affairs published on Tuesday suggests new information on drug violence and its effect on male life expectancy.
The study says Mexico's drug violence was so bad, that at its peak, it apparently caused the nation's male life expectancy to drop by several months.
Drug violence has been increasing in Mexico. In the last decade, dozens of tunnels have been found along the 2,000 mile border with the US. In October, Mexican police found an 800-metre long tunnel -equipped with lighting, ventilation and a rail system for moving goods, authorities said- near the Tijuana border crossing with the US.
According to the authorities, violence and homicide rates have dramatically increased from 2005 to 2010. The study also stated that Mexican men’s life expectancy has decreased by about six-tenths of a year from 2000-2010.
"The unprecedented rise in homicides after 2005 led to a reversal in life expectancy increases among males and a slowdown among females in most states," according to the study, published by Jose Manuel Aburto of the European Doctoral School of Demography, UCLA's Hiram Beltran-Sanchez and two other authors.
Furthermore, the study suggests that the lowest life expectancy among men is clearly seen in Mexico’s top criminal states Chihuahua, Sinaloa, Durango, Guerrero and Nayarit.
"The mortality rate for male’s ages 20-39 in Chihuahua in the period 2005-10 reached unprecedented levels," the study noted.
"It was about 3.1 times higher than the mortality rate of US troops in Iraq between March 2003 and November 2006."
Guerrero is one of the most violent states of Mexico, where over a dozen drug gangs fight control over poppy production and other criminal activities.
