title: [Prevalence of self-reported food allergy and food intolerance and their associated factors in 3 - 12 year-old children in 9 areas in China].
abstract: OBJECTIVE
  To measure the prevalence and the associated factors of food allergy and food intolerance in 3 - 12 year-old children in 9 areas in China.
  
  
  METHODS
  1792 children selected by multistage cluster sampling method from 7 cities and 2 rural areas, from November 2011 to April 2012, with a face-to-face survey to children and their parents, and the logistic regression was used to analyze the associated factors of food allergy and food intolerance of children.
  
  
  RESULTS
  The prevalence of self-reported food allergy and food intolerance were 8. 4% and 7. 7%, respectively. The common foods led to food allergy reported by children's parents were seafood, fish, egg, fruit and milk. The parental allergy was risk factors of food allergy of children (OR = 4. 49 (95% CI 2. 52 - 8. 01), P <0. 01). The picky eating was risk factor of food intolerance of children(OR = 2. 40(95% CI 1. 43 - 4. 02), P < 0. 01). And the education of mother was protective factor of food intolerance of children (the mother with college degree and above relative to with middle school degree and below (OR = 0. 40 (95% CI 0. 20 - 0. 80), P = 0. 01).
  
  
  CONCLUSIONS
  Children' s food allergy and food intolerance were associated with genetic factors and environmental factors included parental education and family economic status. Variable foods were necessary for children' s growth and development, therefore, it is demanded to conduct intervention studies based on the associated factors.
