title: [Study on the risk factors and its interaction on Parkinson disease].
abstract: OBJECTIVE
  To explore the risk factors of Parkinson disease (PD), interaction between family history of PD and other risk factors, as well as the relative strength of genetic factors over the vulnerability of PD.
  
  
  METHODS
  One 1:1 matched case-control study including 157 pairs of cases and controls was conducted in Qilu Hospital of Shandong University.
  
  
  RESULTS
  Conditional logistic regression analysis showed that family history of PD, mental labor, insecticide, alcohol drinking and history of depression all had positive relationship, while smoking had a negative relationship with PD. The AP (AB)s of family history of PD and insecticide, alcohol drinking, history of depression were 55.2%, 34.0%, 41.4% and the RERIs were 8.96, 3.31, 7.85 respectively. The heritability of PD patients' first degree relatives was 36.86% +/- 5.76%, and second degree relatives was 20.66% +/- 6.81%.
  
  
  CONCLUSIONS
  Family history of PD had an additive model synergism on PD, coexisting with other risk factors. Genetic factors had a smaller action on PD than environmental factors.
