Obesity is a growing problem, affecting over 10% of men and 15% of women worldwide in 2011. Restricting fast food advertising on television could reduce childhood obesity by 18% according to US researchers. Mexico has high obesity rates, with every seventh adult classified as obese, second only to the US among developed nations. Children of obese mothers may be at higher risk of autism or developmental delays according to a study from the University of California, Davis. Experts argue that obesity should be treated through medical means like other chronic diseases, and significant measures are needed to address its rising economic and health impacts.
