In California, 7.4 million adults and adolescents were obese in 2011-12. Moreover, obesity among California adults is increasing. The prevalence of adult obesity rose from 19 percent in 2001 to 25 percent in 2011-12. Obesity is a significant risk factor for type 2 diabetes, heart disease, stroke, and some cancers. Although the prevalence of obesity is high among all Californians, it disproportionately affects people of color and the poor. 

Physical activity and dietary behaviors, including levels of consumption of soda and fast food and of fruits and vegetables, are related to obesity. Obesity is also linked with environmental factors such as accessibility and affordability of fresh produce, neighborhood safety, park availability, and social cohesion. Policy and environmental changes that promote positive dietary and physical activity behaviors can address disparities in these areas and help prevent obesity. 

Key findings of this report include: 

• Obesity in California is widespread, but it varies  by county. 
• Obesity disproportionately affects vulnerable Californians.  
• Health behaviors are associated with the prevalence of obesity in California. 
• Obesity is higher among adults who lack access to affordable fruits and vegetables.  
• Neighborhood safety is linked with obesity and physical activity. 
• Social cohesion is linked with obesity and  physical activity.
