Since October 2001, more than 2 million Americans have served in the US wars in Afghanistan and Iraq, and nearly half of these veterans have been deployed more than once (1). Most are adults younger than age 35 when they return home from service. Upon return, veterans can choose to remain active, be inactive while serving in a component such as the Reserves or National Guard, or be separated from service. In the general population, the transition from adolescence to young adulthood is a time of increased risk for behavioral chronic disease risk factors such as excess weight gain and tobacco use escalation. However, few studies have examined the health behaviors of young veterans, and, perhaps as a result, few programs, interventions, and policies are designed to promote healthful behaviors for recently returned veterans. There are a variety of reasons as to why veterans are at increased risk for chronic disease risk behavior. We will also highlight opportunities to develop innovative strategies to promote healthful behaviors among veterans of the wars in Iraq and Afghanistan.
