Food insecurity and levels of marginalization: food accessibility, consumption and concern in Mexico.

Background: Food insecurity continues to be a problem throughout the world. When estimating food insecurity, few studies analyze the contexts where the phenomenon takes place. By bearing in mind levels of marginalization in four states of Mexico, this paper answers two questions: (I) What problems are experienced with access to food, and how these difficulties affect the amount of food consumed in households? and (II) How do households experience the concern of running out of food?

Methods: Our qualitative study draws data from urban and semi-urban areas of four Mexican states: Mexico City, Tamaulipas, the State of Mexico, and Oaxaca.
