Washington, D.C.—More than 1.9 billion people worldwide were overweight in 2010, a 25 percent increase since 2002, a new Worldwatch analysis shows. A survey of statistics in 177 countries shows 38 percent of adults – those 15 years or older – are now overweight. The trend is strongly correlated to rising income and to an increase in preventable health problems, writes Richard H. Weil in the latest Vital Signs Online release from the Worldwatch Institute.
