title: [Synergistic effect of diabetes family history and abnormal waist-to-hip ratio on the incidence of type 2 diabetes].
abstract: OBJECTIVE
  To explore the synergistic effect between diabetes family history and abnormal waist-to-hip ratio (WHR) on the incidence of type 2 diabetes.
  
  
  METHODS
  Population-based case-control study was conducted. The interaction between diabetes family history and abnormal WHR was analysed by an additive model.
  
  
  RESULTS
  After adjusting confounding factors by multiple logistic regression analysis, the synergy index was 5.63, the attributable risk was 1.49, and the attributable interaction percent was 52.9%.
  
  
  CONCLUSIONS
  There was a synergistic effect between diabetes family history and abnormal WHR on the incidence of type 2 diabetes.
