Obesity is a complex problem requiring large-scale, population-based solutions. Public policy
strategies have been identified as critical tools in obesity prevention efforts as they can benefit all
who are exposed rather than simply changing individual behaviors one at a time. This paper
reviews the peer-reviewed scientific U.S.-based literature published between January 2012 and
March 2013 to examine the influence of state laws and local policies on changes to school and
other environments, individual activity and nutrition-related behaviors, and obesity and weight
outcomes. Virtually all recent studies have focused on policies directed at the school environment
and, across-the board, the evidence was mixed. Most studies were cross-sectional, focused on
policy implementation in schools and other settings rather than impacts on individual behaviors or
obesity. Opportunities exist for impact studies focusing on a broader spectrum of policies as well
as for continued policy actions at all levels of government
