title: [Study on undernutrition and overweight coexisting within the same household].
abstract: OBJECTIVE
  To describe the phenomenon of undernutrition and overweight coexisting within the same household on the level of household among 9 provinces in 2000. To explore the likely factors related to the phenomenon.
  
  
  METHODS
  This is a cross sectional study. All households were categorized as four types: undernutrition, overweight, undernutrition/overweight and normal. Multinomial logistic regression was used to test the statistical significance of the association of undernutrition/overweight with sociodemographic factors while controlling for confounders.
  
  
  RESULTS
  In 9 provinces of China, 6.9% of all households were found to have undernutrition and overweight members within the same household. The undernutrition/overweight households were more likely to be urban residence, have a motor vehical,own a washing machine, household head have a low energy occupation and more likely to consume a higher percentage of energy from animal fat. There were no significant differences between undernutrition/overweight and overweight households. There were 34.9% undernutrition/overweight households of all undernutrition households and 13.2% of all overweight households.
  
  
  CONCLUSIONS
  It's essential to explore the phenomenon. The results will suggest the nutrition intervention to consider both undernutrition and chronic disease.
